JPA and indexed collections

Just out of interest, why doesn't JPA support indexed collections? Using ordered lists, if I wanted to insert an object at a particular point, I'd have to do something like this:
myObject.getOrderedList().add(2, childObject);
int i = 0;
for (ChildObject o : myObject.getOrderedList())
o.setIndex(i);
i++;
is that right? If there were indexed lists, I could just do this:
myObject.getIndexedList().add(2, childObject);
Or is there a simpler way to implement ordered lists in JPA?

Best practice for PK and indexes?

Dear All,
What is the best practice for making Primary Key and indexes? Should we keep them in the same tablespace as table or should we create a seperate tableapce for all indexes and Primary Key? Please note I am talking about a table that has 21milion rows at the moment and increasing 10k to 20k rows daily. This table is also heavily involved in daily reports and causing slow performance. Currently the complete table with all associated objects such as indexes and PK is stored in one seperate tablespace. If my way is right then please advise me how can I improve the performance of retrival or DML operation on this table?
Thanks in advance..
Zia Shareef

Well, thanks for valueable advices... I am using Oracle 8i and let me tell you exact problem...
My billing database has two major tables having almost 21 millions rows each... one has collection data and other one for invoices... many reports are showing the data with the joining of Customer + Collection + Invoices tables.
There are 5 common fields in between invoices(reading) and collection tables
YEAR, MONTH, AREA_CODE, CONS_CODE, BILL_TYPE(adtl)
My one of batch process has following update and it is VERY VERY SLOW:
UPDATE reading r
SET bamount (SELECT sum(camount)
FROM collection cl
WHERE r.ryear = cl.byear
AND r.rmonth = cl.bmonth
AND r.area_code = cl.area_code
AND r.cons_code = cl.cons_code
AND r.adtl = cl.adtl)
WHERE area_code = 1
tentatively area_code(1) is having 20,000 consumers
each consuemr may have 72 invoices and against these invoices it may have 200 rows in collection tables (system have provision to record partial payment against one invoice)
NOTE: Please note presently my process is based on cursors so the above query runs for one consumer at one time but just for giving an idea I have made it for whole area.
Mr. Yingkuan, can you please tell me how can I check that the table' statistics is not current and how can I make it current. Is it really effect performance?

Hashmap, Lists and Indexing

Ive had this design problem come up twice already (in the last 3 weeks)
so i figured its time to consult the sages.
Though I know how to use a hashmap in
code I dont really know anything technical about them (or any other map
or hash---). I dont really have a grasp when to use them over ArrayList
or LinkedList aside from obvious key/value situations.
I see them used almost everywhere (I use them almost nowhere). I hear they are faster than get() methods in Lists (which I use always).
Anyway, this is my requirement:
I have an object that has a unique index (ordering value).
this index isnt the position that the object has in the list its just some number or numbers that are sortable and unique (and usually not
consequtive).
Example:
13
105
106
418
2107
(not 1, 2, 3, 4, 5)
I could have from 0-30,000+ of these objects. Right now im using a LinkedList because from what I understand they are better for random insertion (which there will be a lot of).
Because I dont have technical knowledge of Hashmaps i dont
use them - but I thought the index numbers would make good keys (theyre guarenteed to be unique).
Heres the problem. When I grab a random object I (as a requirement)
need to be able to get the previous/next object. Using the example above: if im at object indexed 105 id need to know that object indexed
13 is the previous entry in the collection.
I did research this and the Hashmap API specifically says:
"This class makes no guarantees as to the order of the map; in particular, it does not guarantee that the order will remain constant over time."
So Hashmap is unuseable for my purposes right?
Right now i am using a binary search with a comparator to always
insert objects into the LinkedList sorted ascendingly by that index number. I am using the same binary search and comparator to then retrieve an object quickly. To grab the previous object I get the object
in the previous element and grab its index number.
So my question is: are my assertions correct? is my linkedlist with a
binary search for keeping it sorted and quickly accessible an ok method?
thanks for any input!

Thanks. The indices are unique.
How do you get the previous entry in a TreeMap
(because you wont
have the key)?I think you would have to maintain a copy of the keys in an ArrayList and use Collections.sort() every time a new key is added/removed. Use the ArrayList to randomly pick a key and its adjacent keys which you would then in turn use to retrieve the object from a Map (because order here don't matter anymore).

Hi,
Try following the JPA tutorials for WebLogic, JPA using EclipseLink or Hibernate will be the same if you stick to the specification. WebLogic 10.3.4.0 ships with a Java EE 6 compliant JPA 2.0 implementation in EclipseLink - you may want to give that a try.
http://wiki.eclipse.org/EclipseLink/Examples/JPA/WebLogic_Web_Tutorial
http://wiki.eclipse.org/EclipseLink/Examples/Distributed
I also have a JBoss 6 tutorial for getting JPA working as well.
BTW, your persistence unit is currently application managed - try switching to container managed - then most of your jar dependencies will go away as everything is already setup for you to do dependency injection via the container.

thank you

UCM Indexer - Collection Rebuild Cycle errorring out

We are trying to run the indexer on a huge set of jpg files. The current count is around 2 Million. After we start the collection rebuild cycle, we get following errors. Can someone advise how to fix this? The first two errors are repetitive and ultimately indexing is aborted when we get the last error.

Some possible debugging ideas. (in no particular order)
1. Run IdcAnalyze (see the Trouble shooting guide in the documentation for details on how to run it). It is used to look at the existing file system, DB, and index. It can offer options (in the form of a batch file you can choose to execute) to fix issues.
2. Examine the files and CS settings to see what it is doing. In specific since this example is purely JPG files (non text non full text indexed) does this CS involve an IBR? The inbound Refinery settings may be off and keeping things from progressing to indexing. Conversion happens before indexing.
While debugging do set Verbose logging on sections (at least these sections but you can do more if you like) system,index* (the * is a wild card to allow for all index tracing sections)

For and Build collect

Hi
My office DB is on Oracle version 10.2.0.3.0. Could you please advise if it is possible to use Bulk collect when fetching record from Cursor using For loop?
Thanks in advance,
Tinku

Hi Tinku,
Several people are suggested you regarding bulk bind and for all. It is required for your requirement. They said 100% correct. But still you want to know the bulk collect..Just have a look the below code. just for your knowledge sake I am giving.
BULK BINDS
There are two type of bulk binds are there which are FORALL and BULK COLLECT
FORALL : It sends the all DML operations to SQL Engine at a time from PL/SQL engine
Bulk Collect : It retrieve entire result set from SQL Engine to PL/SQL Engine at time.
By using the bulk binds we can increase the performance. Using BULK binds will decrease the number of context switches between PLSQL and the SQL engine
create or replace procedure bulkbind is
   type vdeptno is table of number index by binary_integer;
   type vdname is table of varchar2(40) index by binary_integer;
   type vloc is table of varchar2(40) index by binary_integer;
   ldeptno vdeptno ;
   ldname vdname;
   lloc vloc;
   cursor dept_cur is select deptno, dname, loc from dept;
begin
    open dept_cur ;
    loop
      fetch dept_cur bulk collect into ldeptno, ldname, lloc limit 5;
      forall i in 1..ldeptno.count
       insert into tempdept values(ldeptno(i), ldname(i), lloc(i));
      exit when dept_cur%notfound;
    end loop;
end;

What is the difference between Topic Keywords and Index File Keywords?

What is the difference between Topic Keywords and Index File Keywords? Any advantages to using one over the other? Do they appear differently in the generated index?
RH9.0.2.271
I'm using Webhelp

Hi there
When you create a RoboHelp project you end up with many different ancillary files that are used to store different bits of information. Many of these files bear the name you assigned to the project at the time you created it. The index file has the project name and it ends with a .HHK file extension. (HHK meaning HTML Help Keywords)
Generally, unless you change RoboHelp's settings, you add keywords to this file and associate topics to the keywords via the Index pod. At the time you compile a CHM or generate other types of output, the file is consulted and the index is built.
As I said earlier, the default is to add keywords to the Index file until you configure RoboHelp to add the keywords to the topics themselves. Once you change this, any keyword added will become a META tag in the topic code. If your keyword is BOFFO, the META tag would look like this:
<meta name="MS-HKWD" content="BOFFO" />
When the help is compiled or generated, the Index (.HHK) file is consulted as normal, but any topics containing keywords added in this manner are also added to the Index you end up with. From the appearance perspective, the end user woudn't know the difference or be able to tell. Heck, if all you ever did was interact with the Index pod, you, as an author wouldn't know either. Well, other than the fact that the icons appear differently.
Operationally, keywords added to the topics themselves may hold an advantage in that if you were to import these topics into other projects, the Index keywords would already be present.
Hopefully this helps... Rick

Different b/w index rebuild and index rebuild online

hi..guys could u plz tel me difference between index rebuild and index rebuild online

There is no difference in both the commands. Both will rebuild the index structure from the scratch.But in the first case with only Rebuild, as long as the index, its temporary segment is not prepared and merged together, index is not available for the other users for use. The Online clause makes the index available for others even while being rebuild.
Rebuilding index online has the same concept of creating them online to some extent,

DB02 view is empty on Table and Index analyses DB2 9.7 after system copy

Dear All,
I did the Quality refresh by System copy export/import method. ECC6 on HP-UX DB29.7.
After Import Runstats status n Db02 for Table and Index analysis was empty and all value showing '-1'. Eventhough
a) all standard backgrnd job scheduled in sm36
b) Automatic runstats are enabled in db2 parameters
c) Reorgchk all scheduled periodically from db13 and already ran twice.
4) 'reorgchk update statistics on table all' was also ran on db2 level.
but Run stats staus in db02 was not getting updated. Its empty.
Please suggest.
Regards
Vinay

Hi Deepak,
Yes, that is possible (but only offline backup). But for the new features like reclaimable tablespace (to lower the high watermark)
it's better to export/import with systemcopy.
Also with systemcopy you can use index compression.
After backup and restore you can have also reclaimable tablespace, but you have to create new tablespaces
and then work with db6conv and online table move to move one tablespace online to the new one.
Best regards,
Joachim

Ceartion of User Defined Field in EXCHANGE RATE AND INDEXES

Hi Experts,
I want to create User Defined Field in EXCHANGE RATE AND INDEXES.But while creating the UDF from User Defined Field-Management unable to find the table for it.Write now My Client are using SAP B1 2007 Ptach-08.Is there any way out to create user defined field in EXCHANGE RATE AND INDEXES.
Plz help me out on this issue.
with regards,
Pankaj K and Kamlesh N

Pankaj,
When you do the Manage User Fields area to define a UDF, all the possible areas where UDF's can be created in B1 is listed. You would be able to create UDF's only on these.

Table files and Index files 2GB on Windows 2003 Server SP2 32-bit

I'm new to Oracle and I've ran into the problem where my Table files and Index files are > 2GB. I have an Oracle instance running version 10.2.0.3.0. I have a number of tables file and index files that have a current files size of 1.99GB. My Oracle crashes about three times a week because of a "Write Fault/Failure. I've detemined that the RDBM is trying to write a index or table files > 2GB. When this occurs it crashes.
I've been reading the Oracle knowledge base that it suggest that there is a fix or release of Oracle 10g to resolve this problem. However, I've been unable to locate any fix or release to address my issue. Does such a fix or release exist? How do I address this issue? I'm from the world of MS SQL and IBM DB2 and we don't have this issue. I am running and NTFS files system. Could this be issue be related to an Windows Fix?
Surely Oracle can handel databases > 2GB.
Thanks in advance for any help.

After reading your response it appears that my real problem has to do with checking pointing. I've included below a copy of the error message:

when running index.php from Netbeans.
Somehow, my settings are not correctly configured anymore.
Here are my screenshots from Dreamweaver > manage sites.
I believe that this is a rather simple fix that I am somehow not seeing.
Maybe some can spot some mistake.
I appreciate your help and explanation.

Hi Sudarshan.
You have been very kind and very clear in your explanation.
One of the very best that I have ever communicated with on this forum !
I have checked many, many things.
I wanted to make certain that I killed apache and restarted it.
I do not think it is RUNNING at all.
1.
myNameMacBookPro:~ myName$ pwd
/Users/myName
2.
myNameMacBookPro:~ myName$ ps -ax | grep http
1892 ttys000    0:00.00 grep http
3.
myNameMacBookPro: myName$ hostname
local
4.
myNameMacBookPro:etc myName$ cd apache2
reginaMacBookPro:apache2 myName$ ls
extra            httpd.conf.pre-update    mime.types        other
httpd.conf        magic            original        users
5.
myNameMacBookPro:apache2 myName$ sudo nano httpd.conf
myNameMacBookPro:apache2 myName$ sudo apachectl -k restart
Syntax error on line 1 of /private/etc/apache2/users/myNameBU.conf:

httpd not running, trying to start
myNameMacBookPro:apache2 myName$
6.
The above code may be a hint at part of the problem.
I created myNameBU.conf as a backup when I was editing the file.
QUESTION. Why is /private/etc/apache2/users/myNameBU.conf:
being referenced above ?
7.
I scanned my ports from preferences and found these two which I believe are what you stated they should be.
port 80 is html
port 8080 is html-alt
8.
I have modified this line and tried it both ways restarting apachectl each time.
AllowOverride None
AllowOverride All
9.
And here is a part of my httpd.conf.
excerpts.
httpd.conf
# User/Group: The name (or #number) of the user/group to run httpd as.
# It is usually good practice to create a dedicated user and group for
# running httpd, as with most system services.
User _www

# DocumentRoot: The directory out of which you will serve your
# documents. By default, all requests are taken from this directory, but
# symbolic links and aliases may be used to point to other locations.
DocumentRoot "/Library/WebServer/Documents"
# Each directory to which Apache has access can be configured with respect
# to which services and features are allowed and/or disabled in that
# directory (and its subdirectories).
# First, we configure the "default" to be a very restrictive set of
# features.
<Directory />
    Options FollowSymLinks
    AllowOverride None

    Deny from all
</Directory>

I took a look at this too.
usr/bin
#path to httpd binary including options if necessary
HTTPD = "usr/sgin/httpd"
# pick up any environmental variables if test - f /usr/sbin/envvars; then ./usr/sbin/envvars
fi
STATUSURL = "http://localhost:80/server-status

Just a reminder.
I started writing .php scripts with Netbeans IDE.
The programs ran: I got output in the brower. Things worked just fine !
I started writing .php scripts with DreamweaverCC.
The programs NEVER ran.
I have always gotten 'Unable to Connect"
Firefox/Safari can't establish a connection to the server at localhost.'
12.
QUESTION.
At one point I was on the phone with a member of the Adobe Technical Support Team.
They connect to my desktop (only) remotely. I am very cautious about this.
Could something have been inadvertently changed when they did this ?
They do need to connect through a PORT - yes ?
This is very frustrating and I am loosing days of work.
I want to get back to Web Development
I love Adobe products but this should not be such a huge obstacle.
When I called Technical support (after much troubleshooting individually and on this forum)
the fellow told me that the ONLY support FTP - not LOCALHOST.
This makes no sense. People develop 'locally' then put it ftp it in the production stage.
Again, I appreciate your assistance.

Conforming and Indexing Errors, Media Pending, Audio won't play in timeline

I'm working on a desktop PC which is running Windows 7 Professional 64-bit and Adobe Premiere Pro (version CS5.5). It's currently utilizing a second gen. 3.4Ghz i7 2600 processor, 16GB of 1600Mhz RAM, 64GB solid-state drive and a ASUS P8Z68-V Intel Z68 Motherboard with onboard audio (Realtek ALC892 chipset) and onboard video. My problem is this:
The conforming and indexing of all of my imported media never seems to finish regardless of how many times I reopen the project file and wait for it. On the lower right-hand portion of the screen, next to the conforming/indexing progress bar, is a little red "X". When clicked, it pops up with a list of errors that read: "An unexpected error occurred while performing a conform action on the following file...". As a result, my audio channels have no waveform and during playback there are no audible tones or levels. On some video clips there's just text that reads "Media Pending". This only appears to happen with project files that I saved on external hard drives, and I suspect it has something to do with the Media Cache Files folder and how Premiere Pro locates these conform/index files. I've also encountered this problem in CS3 and CS4.
I have a few questions:
1) How do I avoid error messages in regards to indexing and conforming
2) How do you know when indexing/conforming has completed itself? (there doesn't seem to be a progress log or a list of commands/executions)
3) Indexing and conforming appears to be an automatic process, but is there a way to do it manually?
4) What's the best way to setup your media cache files when you click EDIT > PREFERENCES > MEDIA?
5) If I have approximately 1 hour of footage, what's an average wait time for conforming/indexing? What about 5 hours of footage? 10?
6) Adobe recommends not editing until the conforming and indexing has completed itself-- how important is this?
7) Sometimes it appears as though the conforming and indexing has finished, but then I still have problems with playback. Do I have to reopen the project for it to continue with the conforming/indexing progress? I've already determined that the video file I'm working with is intact and free of any corruption.
I'm fine with having to wait for a project to conform and index, but it never seems to complete itself! Any help regarding this matter would be greatly appreciated.

Harm filled in pretty much all the salient details, but I'll do another pass here.
1) How do I avoid error messages in regards to indexing and conforming
Two parts here. One, conforming only happens for certain media files, ie the ones where performance is critical and we can't depend on extracting the audio fast enough for realtime playback. That's basically anything in an .mpeg wrapper, or AVCHD material. So if you edit XDCAM HD/EX or P2, or RED, or even AVIs or QT, those formats don't require audio conforming.
If you're stuck editing AVCHD or MPEG2, then it needs to conform. But, that being said, you shouldn't be getting errors in the first place. I think it's related to your external drives. More below...
2) How do you know when indexing/conforming has completed itself? (there doesn't seem to be a progress log or a list of commands/executions)
Nope, you have a progress status bar indicating which file it's working on. If there's an error, it shows up in the events panel.
3) Indexing and conforming appears to be an automatic process, but is there a way to do it manually?
No.
4) What's the best way to setup your media cache files when you click EDIT > PREFERENCES > MEDIA?
While some people like having the check box for having the conform files beside the media, I hate it. Yes, it means that if you move the project to a different system & reopen, it means that you potentially can avoid recreating CFA files, but I find the drive littering not worth it. I much prefer having setting the Media prefs to point to a specific media drive. Usually a raid, if available. Definitely not an external drive that you disconnect & walk away with. If you don't have a permanent raid on your system, then preferably a dedicated internal drive for media (think along the lines as your Photoshop 'scratch disk'). Failing that, leave it on your C: drive, although with a 64 Gig SSD, you probably don't have much room for transient temporaries.
5) If I have approximately 1 hour of footage, what's an average wait time for conforming/indexing? What about 5 hours of footage? 10?
Like Harm said. Totally dependant on the media container & the speed of your drive i/o. The conforming is iterating through the entire file & pulling audio data, so it's not CPU intensive, it's all i/o.
6) Adobe recommends not editing until the conforming and indexing has completed itself-- how important is this?
If you're trying to play/scrub while conforming, it's going to be pokey. Esp. if you're trying to access the file that's actively being conformd. As I just said, we're hitting the files for all the audio. The i/o is being saturated already, so unless you have a stellar raid, you don't have much headroom.
7) Sometimes it appears as though the conforming and indexing has finished, but then I still have problems with playback. Do I have to reopen the project for it to continue with the conforming/indexing progress? I've already determined that the video file I'm working with is intact and free of any corruption.
You should be good to go. Sounds like there's something else at play here.
Okay, back to what I think is wrong: you don't mention what kind of external drives you're using. You're making a bad assumption that blowing away conformed files & doing a reconform is buggy - I doubt it, as that's the same process that happened when you initially brought in the files. I've blown away my media cache folder multiple times and have never seen failures on reconform. So it's got to be one of two things: either a read error from the source when attempting to pull the audio, or a write error to the destination. Now I don't know where you currently are pointing the media cache directory, or what your source drive is, so I can only speculate.
My suggestion is to do some elimination. Copy one of the files that failed on you to your C drive, & target your media cache directory also to C:. Pick a new project, import your copied file, confirm that it conforms correctly & behaves. Then, try to use the same clip from your external drive, keeping the media cache to C:. If that's still good, then try targeting another (local/internal) drive as your media cache target; close/restart, then import the clip from C:, and then import the clip from your external drive. This troubleshooting should give us something.
PS, if you're trying to edit from external USB drives, good luck. I find it a major PITA that I avoid as much as possible. Firewire isn't much better. I know some people do it successfully, but I think it's a road fraught with peril. These devices are generally not designed for heavy duty I/O and a flaky connection or drive is nothing but pain.
Cheers

Report to find all table and index sizes

Hi all,
Good day..
Is there any report.sql or so to find out the sizes of all the tables and indexes in a database.
thanks,
baskar.l

1.To get table size
What will be the table size if?
<or>
break on report
