Enhancement Request: Recalculate Sequence Numbers

Hi
Wherever apex has sequence numbers (for branchs, items, regions etc.), please could we have the ability to recalculate them based on increments of ten so for example items as follows:
P_ITEM1 - sequence = 1
P_ITEM1 - sequence = 11
P_ITEM1 - sequence = 12
P_ITEM1 - sequence = 100
P_ITEM1 - sequence = 120
Would become:
P_ITEM1 - sequence = 10
P_ITEM1 - sequence = 20
P_ITEM1 - sequence = 30
P_ITEM1 - sequence = 40
P_ITEM1 - sequence = 50
The option to exclude items with a sequence number of 999 from the recalculation would also be handy. This can become a bit of a pain when a page has been updated many times and you end up with bunching of sequence number so that if something has to be inserted between them, you have to edit a number of items or whatever to make that happen.
If you could do a page-wide or application-wide recalculation - t'would also be cool.
If this feature is available already, please point me to it.
Cheers
Ben

The Cleanup feature Paul mentioned is new in 4.0 but fyi in any version component sequence numbers accept non-integer values so you can always insert something anywhere without a need to resequence...Thanks! I never knew that! Oh yes. And they can be negative too. We have some very esoteric looking sequences...
Actually the decimals are pretty useful for things like conditional display of regions. If you've got 3 related but mutually exclusive regions, numbering them 20.1, 20.2, and 20.3 indicates the relationship between them. Which brings me to another enhancement request: regions to have separate name and title properties (like pages do), so that where such regions have to have the same title shown to users, it's a lot easier for developers to tell them apart.

OWB 10gR2 - some enhancement requests

Hi, I've been working with OWB 10gR2 for approximately a week now, and I've come across a few (minor) bugs, as well as a list of enhancements that I think would make the tool better. I'd like to surface these in this forum so they can be either disagreed with or have workarounds suggested, as well as getting this list in front of Oracle. Also I'm new to the tool, so maybe there are ways to accomplish what I want.
p.s. as a side note - please don't take these as criticisms of the tool. I'm actually very impressed with OWB 10gR2, but just want to surface some ideas that I think would make the tool better.
Thanks,
Scott
---Bugs:
1.     If I enter a quote character in one of the business description fields (i.e. for a cube or dimension), it causes the DDL scripts to blow up. It probably mentions the list of valid characters in the users guide somewhere - but if a character isn't legal, it should be flagged when I try to enter it originally not when deploying
2.     I can enter illegal strings in an expression operator that fail validation there, but the whole map still passes validation. For instance, I put in an expression (for a varchar2 field) using a single quote at the start, but mistakenly with a double quote at the end. I didnt bother to validate this within the expression. The whole map validated fine, but (of course) blew up with the illegal syntax when generating the code.
3.     I get the following error when trying to browse a cube (ROLAP, not MOLAP) through OWB, but I'm able to pull the cube up fine using either the excel add-in or biBeans: CubeDV_OLAPSchemaConnectionException_ENT_06952???
---Enhancement Requests:
1.     Add a deploy button in control center next to the to default actions and reset actions buttons
2.     Allow an option to have dimensions and cube defaults set to either deploy all, deploy data only, deploy catalog only, deploy aggregations (for cubes). Also, why is the default set to deploy data only? Does deploying the CMW2 metadata involve huge performance impacts or something? It seems like the CMW2 is almost free so it should be turned on by default. Its a pain to use the dimension wizard, but then have to go in to each dimension afterwards to set this option.
3.     When using configure on dims and cubes in control center, the first time the configuration properties dialog pops up, everything is fine. However, when you try to configure the 2nd object, the background focus switches from control center back to design center. This makes navigation very slow if you have lots of items to change. I've noticed this behavior in a few other places as well.
4.     Some dialogs do not have maximize buttons (i.e. dimension wizard dialogs), and default to a very small size. It is possible to have size of dialogs dynamically scaled to screen resolutions, and attempt to size columns so they fit properly. Or better yet, have each dialog remember how large it was last time, and automatically open up to that size?
5.     When generating the autobind relational table while creating a dimension, it seems to be randomizing the order of the attributes within a level (although it does sort the top level attributes first, followed by lower level attributes), at least when using the dimension wizard. It would be nice if the attributes in the relational table came out sorted in the same order as they are specified in the attributes tab.
6.     When using a unmapped display set there doesnt seem to be a way to refresh the set (i.e. remove the items that have since been mapped) unless you select all and then unmapped again. Would be nice if you could simply choose unmapped again and have it refresh the object
7.     While doing a mapping, right click on canvas allows option to generate. Would be nice to also add the validate option to this menu
8.     Validating mappings takes a decent amount of time would be nice if a busy icon was displayed to let user know that OWB hasnt locked up.
9.     default size of job details dialog is too small, and even if I maximize I still have to go through and manually adjust the size of each pane. Similar to enhancement #4
10.     Horizontal size of operators in mapping seems to be determined by the length of the operator name, instead of tying directly to the icon. Looks strange. Very minor
11.     When displaying dimension objects in a mapping:
a.     For the surrogate key columns add an icon to indicate this attribute is a surrogate key. Likewise, since its not legal to map anything to this column, remove the little arrow next to it (the one that turns gray when something is mapped to a column), or perhaps don't even show this column at all.
b.     For the business key columns add some type of icon to show which attributes represent the business natural key (or make color different, etc.)
12.     Similar to #11, for the cube operator in a mapping:
a.     For the surrogate key columns if they cant be mapped to, then dont show them
b.     For the business key columns add some type of icon to show which attributes represent the business natural key
c.     Separate the measure columns from the dimension columns
13.     For the Aggregation operator can you move the <None> default operator to the top of the list. At the bottom, it means you always have to scroll to use the most common operations (which are at the top of the list), i.e. sum and avg, etc.
14.     In the log on prompt, if I choose SQL*Net connection, every time I start it up it defaults to the details being shown (even when I chose no detail last time), with cursor in the host box. I should be able to have the details hidden, and this dialog should ALWAYS default to having the active cursor in the password box on startup
15.     When printing in a mapping, the page setup print dialog is very slow. Also, the print setup dialog shows margins, but you cant adjust them. It would be nice if this could be changed here
16.     Add a print preview icon to all of the toolbars. Printer icon is there, print preview should also be.
17.     In the dimension attributes, we need a way to tag an attribute as being the insert record date or the update record date. The corresponding MERGE SQL should be updated to use these attributes.
18.     It would be nice if the mapping canvas defaulted to an unlimited sizei.e. when I want to add new operators and the screen is already full, I either need to shrink the zoom factor down to the point where I cant read the icons anymore, or I have to pick up the new operator and drag at the bottom / right side until it scrolls enough to drop it where I want. If the canvas had an unlimited size, I could simple use the scroll bars to scroll to where I want.
19.     Scroll wheel functionality to zoom in / out (and have it zoom in around the currently selected object)
20.     Option to have operations automatically resize when longer attribute names are added to them (can workaround by mimimizing and then maximizing, but would be better to have the operators automatically adjust size to fit)
21.     Ability to sort output attributes in an operator (just like table column sort functionality). If I create a new operator, it would be nice to group it with related operators instead of always having it at bottom.
22.     re: column sort functionality drag and drop instead of up/down arrows would be nice
23.     It would be nice if, when adding output attributes to (for example) the expression operator, it would choose the default data type the same way the dimension attribute wizard works (i.e. if it sees ind in name, automatically choose char(1)
24.     Change the zoom in button so that it zooms in on the currently selected operator i.e. if I click on a particular table and then hit the zoom in button, it should keep the table I selected centered
25.     When in a mapping, clicking on a line should highlight the attributes on both the source and target operators (to allow easier visual ID of where data is coming from / going to)
26.     AWM has a feature where table attributes can be sorted so that mappings between them don't have "crossed" lines. Similar functionality in OWB would be very appreciated. It may be harder to automate this, but even manual drag and drop of attributes within an operator would be nice.

if you could copy/paste this whole thing into the submission form (see feedback option under the numbers menu). The more people that request these features, the more likely we are to see them in an update or the next version.

Enhancement requests do seem to be worthwhile in the end...

Having requested the continuous/shuffle music video playback several times in the last 18 months or so, and urged people to do so via...
http://www.apple.com/feedback/appletv.html
...it has finally been implemented and I'm chuffed to bits.
Well done Apple, this is a superb enhancement though why so long to implement ?
Personally I feel this was a huge oversight for AppleTV ever since it was realeased, and seriously hindered both use of AppleTV as a media extender and obviated the point of buying music videos unless you watch them on portable devices which I don't.
I had become increasingly negative about the prospect of ever seeing this feature
appear - this cat doesn't wear a hat so I'll have to eat something else instead!
I am now likely to spend a fair amount on music videos at iTunes Store having vowed not to do so again as having to select each one manually to play was tedious to say the least.
Really baffles me how Apple have missed the opportunity for revenue from music video sales via AppleTV, particularly when iPods had the shuffle feature.
As I commented a few weeks ago I think perhaps priorities since 2.0 update have been to get the store up and running properly before implementing enhancement requests or new features.
Very pleased Apple have finally implemented this extremely useful feature, it may not be pointless in using the link above, it just takes time.
So the next thing we should do is think of things to officially lobby for in future updates.
My top 3 would be:
1 - Allowing connection via USB to rescue data from AppleTV for users who've had hard drive accidents/msihaps and haven't backed up recently - fact of life it happens even if you're careful! Files with DRM are safe from unauthorised use and those without DRM are no less secure than they were before anyway. This could even be done by only allowing AppleTV to dump media to an external USB device instead of allowing an external connection to AppleTV itself, and could be controlled from say a backup menu option. Alternatively full manual bidirectional drag and drop of media via iTunes to/from AppleTV could be implemented with a mode to prevent a new sync library connection wiping existing content.
What's in it for Apple? Huge boost in consumer confidence that Apple allow them to easily recover their personal files in the event of a problem - there should be no need to hack or dismantle AppleTV just to get at your data. Just think of all those people saying thank heaven I had an appleTV as my Macbook died and I'd forgotten to backup those wedding photos etc. We see examples of frustrated users almost daily with this problem.
2 - Additional codec support - it's all very well saying h264 is the best thing since sliced bread and the current Apple/Apple Store standard, but the limited video codec support is probably the biggest hindrance to AppleTV becoming an extremely popular media device. It has the slickest interface of commercial products but many prospective customers have files in long established older formats that are incompatible without prior time consuming and quality degrading transcoding. Locking down AppleTV in this way alienates many potential users. The argument about the source of files in other formats may have some validity, but it is not Apple's job to infer that a user's file is of dubious origin simply for not being in h264 format. I am not condoning filesharing/torrents etc merely saying that most people have older files in older formats they want to use without conversion. Many DVD players allow playback of DivX (never use it myself), and if there's a licensing issue offer playback as a per device plugin option paid for by the user in the same way the QT MPEG2 pluging is offered.
What's in it for Apple? Happy customers who would simply use something else like a PS3 to view their files and not buy AppleTV. New customers who would not have purchased otherwise. Happy customers who no longer need to trasncode files to watch. You'd be happy with being able to use older files, but would also get the benefit of using iTunes Store for new things.
The overhwelming thing would be a sense of 'fair play' gained by the consumer. For me personally since 2.0+ the device's overwhelming iTunes Store based menu design sticks in the craw and has relegated MY content to the bottom of menus. Give us the best of both worlds - an iTunes Store top level section for purchases and separate simple top level sections for combined personal/purchased media as in software 1.0/1.1. In essence declutter the menu system for playback lumping all the purchasing/preview/search options together.
3 - Tricky. Most useful would be an AppleTV SDK and 3rd party plugins/apps via iTunes paid and/or free similar to the iPhone model - I can live without widgets/visualisers/social networking plugins etc but they would be valuable to many users. As far as I know the iPhone Apps have been a huge success - no reason why not on AppleTV too, though commiting to this pathway would probably be very expensive in terms of developing a secure/sandboxed environment for running apps/plugins unless they could port the iPhone software fairly simply.
Anyhow, once again delighted Apple have added the music video feature - I will start buying music videos from iTunes music store again. Bad for my wallet but good for Apple and AppleTV. Perhaps I should be thankful and consider how much I've saved not buying music videos in the last 18 months or so.....
What would you like to see? Some things will be impossible/hardware limited, others quite feasible.
Discuss, but also use the formal feedback link to give enhancements any chance to appear!
Let's all help make AppleTV a success, and hopefully the media extender to beat!

to be honest, adding playlists (or whatever it is) for just music videos is of no use to me.
it is playlists for tv shows that i need. ie the capability of playing episode 1 to 5 of a particular season back to back.
Funny isn't it, how we all do things differently, have different preferences, enhancement wishes etc.
For me it's not really a big chore to watch an episode then to manually start the next assuming I or Mrs AC are still awake!
For episodes of short duration say 5-15 minutes I appreciate this could get annoying, and for longer episodes I suppose we are used to Play All type options on DVDs.
If these are iTunes TV Shows you're stuck at the moment, but if they're say 'home recordings converted for AppleTV' you could theoretically get round it by setting their types to Music Video. Clumsy but it should work.
I'm sure you can see the benefit of playlists/shuffling for music videos that may be 3-4 minutes each on average. I rediscovered dozens of iTunes Store music video purchases last night and thought 'yes, this is one of the big reasons why I bought AppleTV initially' - it did not say anywhere that AppleTV could not do this somewhat logical task - assumptions are dangerous though and invariably you only find out the full capabilities of products when using them.
additional codec support ? i would say there is no chance of this. x264 is pretty standard theses days (if you discount the pirate industry). x264 is even used for HD TV in the UK.
I agree, there's more chance of Tony Blair making a comeback!
Piracy is rife and I do not support it.
My views on fair use of media you personally own are quite different.
It's not the codec/container that's the issue it's how the material was acquired in the first place - it may simply be your home videos, digitised off-air recordings etc that is in a 'legacy' format that you don't want to transcode. We know from the modders that most other SD formats are playable on the current hardware so that's not the issue.
Take say an Elgato EyeTV device - I can record anything off-air, edit and transcode for AppleTV or just transcode unedited automatically. How much more sensible it woudl be if AppleTv simply supported the MPEG-2 transport stream playback rather than wasting time and computing/power resources doing the transcode.
I have some some standard video-CDs I made on a PC in the late 1990's, how nice it would be to be able to play the MPEG-1 content back without fiddling - it's not as though converting to h264 will do anything for the quality!

Enhancement Request: Viewlink based on an Association

Hi,
one highly repetitive task is creating associations and then creating a view link which in 99% of cases is an exact representation of the association. An enhancement that I would find useful is a create Viewlink from association context menu. Ie. right click on an Association and select "New View Link from Association". All of the relations from the association would then populate the view link properties.
I know that these can be generated from PK/FK relations but the business components from tables doesn't allow you to specify Association, View Link names or their location, resulting in a big bucket of ADF objects all in one level (this is is probably another enhancement request).
regards,
Brenden

does anyone else feel this would be of benefit?
After months and months spent solidly developing in JDeveloper this is the single most repetitive (and trivial) task i have had to do.

Finding missed sequence numbers and rows from a fact table

Finding missed sequence numbers and rows from a fact table
Hi
I am working on an OLAP date cube with the following schema:
As you can see there is a fact transaction with two dimensions called cardNumber and Sequence. Card dimension contains about three million card numbers.
Sequence dimension contains a sequence number from 0 to 255. Fact transaction contains about 400 million transactions of those cards.
Each transaction has a sequence number in 0 to 255 ranges. If sequence number of transactions of a card reaches to 255 the next transaction would get 0 as a sequence number.
For example if a card has 1000 transactions then sequence numbers are as follows;
Transaction 1 to transaction 256 with sequences from 0 to 255
Transaction 257 to transaction 512 with sequences from 0 to 255
Transaction 513 to transaction 768 with sequences from 0 to 255
Transaction 769 to transaction 1000 with sequences from 0 to 231
The problem is that:
Sometimes there are several missed transactions. For example instead of sequence from 0 to 255, sequences are from 0 to 150 and then from 160 to 255. Here 10 transactions have been missed.
How can I find all missed transactions of all cards with a MDX QUERY?
I really appreciate for helps

Thank you Liao
I need to find missed numbers, In this scenario I want the query to tell the missed numbers are: 151,152,153,154,155,156,157,158,159
Relative transactions are also missed, so I think it is impossible to get them by your MDX query
Suppose this:
date
time
sequence
20140701
23:22:00
149
20140701
23:44:00
150
20140702
8:30:00
160
20140702
9:30:00
161
20140702
11:30:00
162
20140702
11:45:00
163
As you can see the sequence number of the last transaction at the 20140701 is 150
We expecting that the first transaction of the next day should be 151 but it is 160. Those 10 transactions are totally missed and we just need to
find missed sequence numbers

Enhancement Requests for AWM10g

Hi, before I start in on the enhancement requests I want to say that I am pretty impressed with AWM10g. Definitely a huge step forward in creating AWs. Having said that, I think there are a few enhancements that could be done to the tool to make it even more user friendl.
Note that these are in no particular order, just ones I came up with while using the tool. I'll add any others that I come across.
Please don't take this as nit-picking - just trying to help make it better.
Thanks!
Scott
1. On dimension hierarchy types, instead of "value based" call it a "parent / child based" (thats what everyone knows it as)
2. When creating levels, allow more than one level to be created at a time (currently it closes the dialog after each level is created, forcing you to go back and choose "create levels" over and over again). This may be as simple as having a "Save and create another" button or something.
3. When typing names in the "system name" boxes, it would be nice if we could simply type the descriptions using spaces, and have the system name automatically replace with an underscore. Right now its a bit tedious to remember to type all names using underscores.
4. In "mapping" view, move HELP, APPLY, and REVERT buttons off of bottom status bar and up to the top toolbar. There is lots of unused space at the top, creating a second bar at bottom just eats up screen real estate
5. On "create dimension" dialog, no need for an entirely separate tab for "implmentation details" (that only has two values - generate unique keys or use the existing keys). Put this on the front tab so users don't have to keep selecting over to it (unless of course there are additional values that can show up there?)
6. Mapping dimensions with multiple hierarchy - seems odd that we have to remap shared levels. Is it possible to make this where you would map all the values in the first hierarchy, and then only map the "missing" levels in the second hierarchy? Seems like an opportunity for hosing things up
7. Drag and drop ordering when setting up the dimensions in a cube would be nice. Interface is the same as prior version of AWM (pretty clunky)
8. Bug - when typing in any "name" field, if you highlight the entire field and delete all characters, under the "description" fields only a single character gets deleted.
9. When there are multiple hierarchies for a given dimension, some sort of visual indicator of which one is set as default (without having to drill into details of each one)
10. Its difficult (impossible?) to resize panes (for instance, when doing the mapping). Seems like sometimes I click on something by accident (other than the < and > arrows) that resizes the panes, and then I can't figure out how to get them back (other than exiting and restarting)
11. When writing template out to same name as one that exists, AWM2 is not giving a "do you want to overwrite" prompt
12. Some sort of clear visual indicator or message when a dimension is not completely "mapped". I had a dimension where I mistakenly forgot to map the leaf level dimension member. I didn't find out about it until I ran a load and the load blew up.
13. On the XML logging at the end of a load process, the dialog box isn't big enough to show entire error messages if they occur. Since I haven't found a way to actually write the output to a txt file, this makes it hard to debug what is wrong with a solve.

Anthony - thanks! In the meantime, I've come up with a few more requests / suggestions (and will probably have a few more yet to come...)
Thanks again!
Scott
1) Rather than just showing the "working" bar while a load / solve is going on, would it be possible to replace this with some sort of functionality that queries against the OLAPSYS.xml_load_log table? And perhaps allow the user to click "refresh" or have it auto-refresh at a certain number of minutes so that users can actually see the progress being made?
2) Since CATALOG view is no longer available, remove the options to have AWM write the log files

Enhancement request: Remote interface java file generation

Problem:
In release 9.0.3, If you want to write a method that is suppossed to be exposed in the remote interface, you have to first right click on the ejb-jar.xml's appropriate EJB name node and then add the method, specify the argument types (say about 25 in number in a small width textbox), return type, etc and check the check box 'Expose in remote interface'. Then only remote interface's java source gets updated and only after doing all this can you actually sit down to write the business logic in that method. If you first code the method and then try to add the same, it gives an error saying "duplicate method exists"
Suggestion:
The similiar feature in release 9.0.2 was much better and flexible as it allowed the generation of remote interface source after coding the actual method in the EJB source. You can first write the method and then expose it in the interface by just choosing it from a method browser and opting for exposing it in the remote interface. You donot have to write the name and number of arguments like we have to currently do in the 9.0.3 release.
(1) Actually, all public methods in the EJB source should by default be exposed in the remote interface because EJB are supposed to be used by other EJBs and JSPs only and all methods that are public but not exposed in the remote interface should actually be private or protected.
(2) Leave it up to the developer to edit the remote interface
(3) When the EJB source file is changed (public methods changed) compiled the remote interface should also be updated automatically. Why? already you have provision to change the remote interface source, so just dump all the public methods in the remote interface source when the EJB source is compiled.
(4) Ditto for EJB Homes
(5) Actually whenever the developer changes and compiles the EJB source, the remote and home source should automatically be updated AND COMPILED. (Refer: Pramati Studio 3.0 SP3 :- URL: www.pramati.com )
I was very happy with the earlier option. If anybody other then the JDeveloper Team finds this interesting, please respond. A suite like developer should be more User-friendly.
And yes expect more like this from me in the future

Hi Raghu,
Thanks for the quick response. This flexiblity in Remote interface generation and choice of methods in it at any given point in the development cycle is very much desired feature.
The other thing I would like to suggest is you look at another enhancement request in my name regarding batch updates of the "web.xml" file. You will find the thread updated today i.e. on 15th September with a reply
I will shortly post one more for lack of modularity in EJB components descriptors.
My Company Four Soft Pvt. Ltd. (www.four-soft.com) is Oracle's development partner and we use and support Oracle products. They are good but naturally we would like them to be better and more User-friendly.
Thanks once again.

LR3 Web Gallery Sequence Numbering bug?

Anyone else getting this problem with sequence numbering in the web HTML templates? Basically, as you jump through photos the photo number is always stuck on #1, never changes when you go to the next photo - should go 1, 2, 3, 4, 5...
I just sent a bug report but, wondering if anyone else found a fix for this yet.
This is in LR3 on Mac - really trying to do this on TTG Highslide gallery but, same problem occurs in default Lightroom HTML gallery.
Thanks.
******BUG******
Concise problem statement:
Steps to reproduce bug:
1. Go to Web Module
2. Choose default HTML Gallery
3. Under Image Info set Caption to Sequence
Results:
Sequence caption always shows 1/total images.
i.e. 1/10, 1/10, 1/10, 1/10
Expected results:
Sequence should increment current image number / total images as you click through images.
i.e. 1/10, 2/10, 3/10, 4/10

Yeah, still have the numbering problem using the Image Info sequence outputs.
But, if you use the standard Lightroom Flash Gallery it has it's own sequence numbering output (that does not use Image Info captions) and it does work correctly. These show up as 1/9, 2/9, 3/9 etc. on each photo down by the back/next buttons.
Also, the Cell Numbering does work when using the Lightroom HTML Gallery - though, those numbers only appear on the index page not on individual photos.
But, haven't seen a good work-around yet for sequence numbering in Image Info area. Only option there seems to be typing numbers manually into the caption. Or, if you need the caption for other info maybe use one of the IPTC fields like Headline to type in your numbers. You can then do a Custom Setting in web module to have those text fields show up with your photos.
Really hoping we will see a LR 3.1 sometime soon with a fix - should be an easy correction for Adobe.

Sequence numbers not generated sequentially?

Our situation: We have encountered an issue with our database, where it appears that a sequence has generated a number out of sequence, that is, to fill in a gap left previously. That is, in the affected table, we have records like:
Seq No Date (DD/MM/YY)
1 29/12/08
2 29/12/08
3 4/1/09
4 29/12/08
The code that actually updates the database is from a third party, so I am unable to prove the following, but the vendor assures me that:
1. The sequence numbers are generated using "select message_number.nextval from dual".
2. The Date column is not modified after the record is created. ( Nor is it supposed to be )
The sequence is created by "CREATE SEQUENCE MESSAGE_NUMBER START WITH 10000000 INCREMENT BY 1 MINVALUE 10000000 CACHE 20 NOCYCLE NOORDER"
This was detected only yesterday, after the event, and is very uncommon ( I have not found another instance, but there are over 7,000,000 records, so I haven't performed an exhaustive search). We are relying on the sequence numbers always being generated sequentially, as in each message_number.nextval is greater than the previous one.
I don't think that the date change was due to a user accidentaly changing the date. Related records to '3' are also dated 4/1/09, there is no facility for a user to change the date outside of accessing the database directly, and even the developers do not have write access to this database.
My questions:
1. Is this normal behaviour for a sequence? To go back and fill in a gap like this? If so we'll have to change one of the assumptions of one of our modules.
2. Should the sequence be defined with 'ORDER' rather than 'NOORDER' to stop this?
3. Could this be a bug in the sequence number generation? We are using Oracle 9.2.0.1.0.
4. Is this situation "impossible", and therefore there is a bug in the vendor library that we need to track down.
Thanks for your help,
Wayne.

Our situation: We have encountered an issue with our database, where it appears that a sequence has generated a number out of sequence, that is, to fill in a gap left previously. That is, in the affected table, we have records like:
Seq No Date (DD/MM/YY)
1 29/12/08
2 29/12/08
3 4/1/09
4 29/12/08
The code that actually updates the database is from a third party, so I am unable to prove the following, but the vendor assures me that:
1. The sequence numbers are generated using "select message_number.nextval from dual".
2. The Date column is not modified after the record is created. ( Nor is it supposed to be )There might be a delay between fetching the sequence and storing the sysdate? value in the database.
maybe some user prepared a new record. Then went to some new years eve party and when he came back at the begining of next year he commited the data (record send to database, database is adding date column by some trigger...).

The sequence is created by "CREATE SEQUENCE MESSAGE_NUMBER START WITH 10000000 INCREMENT BY 1 MINVALUE 10000000 CACHE 20 NOCYCLE NOORDER"
This was detected only yesterday, after the event, and is very uncommon ( I have not found another instance, but there are over 7,000,000 records, so I haven't performed an exhaustive search). We are relying on the sequence numbers always being generated sequentially, as in each message_number.nextval is greater than the previous one.

However it is possible to fetch and cache values from a sequence for later usage. Especially in a RAC environment you can get sequence values that are not in order of time.

3. Could this be a bug in the sequence number generation? We are using Oracle 9.2.0.1.0.Extremly unlikely, but you can always check Metalink.
4. Is this situation "impossible", and therefore there is a bug in the vendor library that we need to track down.You can create such situations programatically. Whether it is a bug depends on the specifications for the software.

Page item sequence numbers

Maybe this one is for a future improvement...
After reordering page items using the drag and drop feature the items all have a sequence number one greater than it's predecessor.
This makes it hard to put a new item in between existing ones. Generating sequence numbers 5 or 10 apart would make this a bit easier.

hi,
i dont know whether you have tried this before...
10
10.1
10.2
10.3
20
20.1
20.2
30
this is acceptable in apex item sequence number for inserting new items .
Thanks

Documents Sequence numbering for each Branch (Branch as segment)

dear Brother's
can help me in this case
Documents Sequence numbering for each Branch (Branch as segment)
Each branch have an own sequence
I implement oracle Business suite ERP for Five Branch ( KSA,INDIA,DUBIA ,JORDAN ,SYRIA )
I want to segregate sequence numbering for each branch, sequence for (
Sales order, invoice, purchase order, Invoice)
Is there a possibility to link sequence with any segment I define it in COA like Branch
Note: I work in single Operating Unit

Hi,
You might be able to adapt this solution to work for your case: https://acrobat.com/#d=*2slxPLc6c-H0U449vA4jQ. It's more about page numbers for different Master Pages, but you may be able to tie it to the different data nodes.

Enhancement Request - comments

I've recently demonstrated the SQL Workshop within HTMLDB to a number of users of varying experience, and the response has been very positive indeed. However, a common complaint was that there is very little table and column specific (i.e. metadata) available through the object browser and the query builder. One way that this type of information might be held is through table and column comments (e.g. user_tab_comments and user_col_comments) however comments are not displayed in the object browser or query builder.
Also, Although there's a table comment report in the utilities in the SQL Workshop, there is no easy (i.e. other than writing SQL) way of putting comments on tables, columns etc.
Thus the main enhancement request is for comments on tables and columns displayed in the object browser and the query builder, and a follow up would be for the GUI to provide a method of maintaining that information.
Alternatively, if a some links (i.e. on the table and individual columns) could be added to the object browser/query builder which linked to a customisable application (something akin to the security models), then metadata could be served through a custom built application. This would, IMHO, be the best approach - in fact the display of column and table comments could be the default, but allow an over-ride for a custom app.

Simon,
Thanks for this feedback. We will take it into consideration.

Archive log missing on standby: FAL[client]: Failed to request gap sequence

My current environment is Oracle 10.2.0.4 with ASM 10.2.0.4 on a 2 node RAC in production and a standby that is the same setup. I'm also running on Oracle Linux 5. Almost daily now an archivelog doesnt make it to the standby and oracle doesnt seem to resolve the gap sequence from the primary. If I stop and restart recovery it gets the logfile and continues recovery just fine. I have checked my fal_client and fal_server settings and they look good. The logs after this error do continue to get written to the standby but the standby wont continue recovery until I stop and restart recovery and it fetches this missing log.
The only thing I know thats happening is that the firewall people are disconnecting any connections that are inactive for 60 minutes and recently did an upgrade that they are claiming didnt change anything:) I dont know if this is causing this problem or not. Any thoughts on what might be happening?

It's the network that's messing up; unlikely due to firewall timeout as it waits for 60 minutes and you are switching every 15 minutes. There may be some other network glitch that needs rectified.
In any case - arch file missing/ corrupt / halfway through - FAL setting should have refetched the problematic archive log automatically.
As many had suggested already, the best way to resolve RFS issues I believe is to use real-time apply by configuring standby redo logs. It's very easy to configure it and you can opt for real-time apply even in max-performance mode that you are using right now.
Even though you are maintaining (I guess) 1-1 between primary & standby instances, you can provide both primary instances in fal_server (like fal_server=string1,string2). See if that helps.
lastly, check if you are having simiar issue at other times as well that might be getting rectified automatically as expected.

Enhancement request for more fine-grained templates

JHeadstart version : 10.1.2.0
I like to have the possibility to define templates on the level of table rows. If I am correct, currently the 'lowest' level of a .jtt template is the $FORM_ITEMS$ token. According to the userguide this token "is used to indicate the place where a form must be generated". My question is now: How can I influence this generation process? For example, I want to embed text-items within <c:if's in order to conditionally set a text-item attribute. Am I right to conclude that on this "deeper" level of a jsp (for instance table-row level), it is not possible to define templates?
If so, I want to request an enhancement for a further 'fine-graining' of the templating technique.
Thanks and greetings, Erik

Erik,
Yes, this is not possible in he current release.
Your enhancement request has already been implemented for the JDev10.1.3/Faces release. We will the support two kinds of tokens, one that outputs all items as it is today ($FORM_ITEMS$ or $TABLE_ITEMS$), and one token that refers to an individual item. This reference can be bpoth on index number and name:
FORM_ITEM_1 or
FORM_ITEM_DepartmentName
This will allow you to layout the items exactly as you want.
Note that in the 10.1.3 release, we will also support item-level templates where you can add code to conditonally render items.

JHeadstart Team.
