Warn about Changes

Hi,
I have a few questions on "Warn About Changes" feature in 12i.
1. When the Warn about changes message will be thrown ?
2. In my page, im using the ViewObject (OAViewObjectImpl type) and setting its row attribute programmatically. But still not getting the Warn about Changes message as VO should be dirty in this case. How to overcome this ?
3. In my another page, im using ViewObject (extends OAPlsqlViewObjectImpl class). This triggers the Warn About Changes on setting the Row attributes programmatically. But for some of attributes, i want to suppress the message on page rendering and enable it on user action. is there any way to do it ?
4. Also if i want to throw the same type of message using JavaScript, please help me with the approach of catching the event and throwing the message.
Thanks in Advance !!!
Best Regards,
Senthil.

Hi,
1. When the Warn about changes message will be thrown ?
Answer: warn about changes will be thrown whenever there are changes in the Application State.
2. In my page, im using the ViewObject (OAViewObjectImpl type) and setting its row attribute programmatically. But still not getting the Warn about Changes message as VO should be dirty in this case. How to overcome this ?
Answer: Have you set the warn about changes property to "true" on the pagelayout region???
4. Also if i want to throw the same type of message using JavaScript, please help me with the approach of catching the event and throwing the message.
Answer: you can check if (vo.isdirty()) then you can throw a message.
Thanks,

About the warning about changes message.

Hi all,
There is a messageChoice on the page,and the messageChoice must fire an action.But if the action is fired,then I click on the other tab or link, warning about changes message will not occur and directly farward to the other page.Is that possible that popup the warning about changes message after the messageChoice's event was fired ?
Thanks,

Hi,
this question is hard to understand. I don't see a messageChoice component in ADF Faces, can you give more details to your usecase and the components involved

But if i add new line and try to click on other main tab i am not getting alert pop up message (warning message).
Can anyone tell me how to resolve this issue?

Hi Babu
Handeling of warn about changes is covered in the OAF development guide under Save Model("Warn About Changes")

Warn About Changes and page flow

Hi, in dev guide, it is said:
For any single page, or first page in a navigation flow where the retainAM URL parameter value is set to Y (and the pages share the same root UI application module) as you navigate between each page, set the Warn About Changes property to True on the pageLayout region.
in other word, if pages in page flow are in the same AM, after changing am in the first page, anytime leave the following page to click the home link(oracle branding), the WarnAboutChanges msg should be alerted?
But,
Now I have two pages, using the same AM, set the two pages' property "Warn About Changes" to true.
And I want to implement this: after inputing some words, and click a sunmitButton forward to pageB(add retainAM = Y in setForwardURL in code), then in pageB don't do anything, but click home link, WarnAboutChanges message does not alert.
Could anyone help to explain this?
And how to implement the page flow warnAboutChanges?
And how root application module to set if different pages in different AMs?
PreThanks to you very much!

But,
Now I have two pages, using the same AM, set the two pages' property "Warn About Changes" to true.
And I want to implement this: after inputing some words, and click a sunmitButton forward to pageB(add retainAM = Y in setForwardURL in code), then in pageB don't do anything, but click home link, WarnAboutChanges message does not alert.
Could anyone help to explain this?
I asked u previously also read dev guide properly, here it what dev guide say:
"By default, the Warn About Changes property is set to True for each of the items in this list except for the
OASubmitButtonBean whose default value is False (a ccording to the UI guidelines, the "Warn About
Changes" check should be performed for all submit button instances except for Cancel, Apply and Submit
buttons). If you want to explicitly enable the check for a submit button, set this property to True. Note that can
also set it programmatically by calling OASubmitButtonBean.setWarnAboutChanges(pageContext,
Boolean.TRUE) in processRequest()."
I hope this answers ur question.
And how to implement the page flow warnAboutChanges?
Read "Save Model ('Warn About Changes')" in dev guide :).And how root application module to set if different pages in different AMs?
You can nest differnt AMs in on AM in AM wizard.--Mukul

Printable Page - Warn About Changes issue

Hi,
I am implementing Printable Page functionality by giving TargetFrame = _blank. And also I am setting Warn About Changes property to True. (pageLayoutRN's WarnAboutChanges is also set to True)
But after making some changes in the page and If I click the Printable Page button, the Save Model warning is not coming.
Any solution ?
SenthilKumar J

I guess then it explains the issue. Save model gets invoked only on the following scenario:
# Selecting a tab, horizontal navigation or side navigation menu entry
# Selecting a global button (implies retainAM=N)
# Selecting a breadcrumb link.
# Selecting a link with URL parameter retainAM=Y and the Warn About Changes property set to True (note that this applies only to declaratively defined links; this does not apply to menu links)
# Selecting an image which does not post your changes. For example, selecting an LOV icon or a long tip window will not trigger the save model warning. However, if the user selects on an image that navigates to Yahoo, for example, the warning is displayed.
# Selecting a link that performs a form submit and has the Warn About Changes property set to True.

Urgent: Getting warn while changing a field value...How to disable this?

Hi All,
I have one customizated PG which is getting different parameter value from a seeded PG.
Now in Seeded PG there is multiple line (multiple line requisition) with Qualtity & Price field. We have added one link for each line. This link is custom one. Now what we are facing is whenever user change the vakue in Quantity or Price User getting "The changes you made to this page have not been saved. If you continue, the changes will be discarded. Do you wish to continue." warning. Due to this the current change is not reflecting in next PG that is custom PG.
I have tried to make false of the property of "Warn About Changes" of that field. Though m not able to turn of that warning. Could you please let me know what can be done to turn of this waring?
Thanks

Hi,
Here is the code I m using now...But m getting null pointer exception when I M clicking the last line of the multiple line requisition.
String reqLine = pageContext.getParameter("RequisitionLineId");
if(pageContext.isLoggingEnabled(1))
pageContext.writeDiagnostics(this, "processFormRequest reqLine from parameter " + reqLine, 1);
ChangeOrderAMImpl am = (ChangeOrderAMImpl)pageContext.getApplicationModule(webBean);
ChangeOrderLinesVOImpl vo = am.getChangeOrderLinesVO();
//Debashree
int length = vo.getRowCount();
if(pageContext.isLoggingEnabled(1))
pageContext.writeDiagnostics(this, " row.length " + length, 1);
//Debashree
ChangeOrderLinesVORowImpl row = (ChangeOrderLinesVORowImpl)vo.first();
String strQuantity = null;
String strUnitPrc = null;
do

Getconf returns compiler flags that the compiler warns about

I have Workshop 12u1 installed on my Solaris 10u8 machine (x86_64). I'm up to date with patches as of a couple weeks ago.
I'm well aware that the Workshop suite has deprecated flags like -xarch=generic64, -xarch=amd64a, etc.
However, when I run "getconf" on my Solaris 10 system, some of the conf settings still return those older flags that the compiler now warns about. That causes a lot of warning chatter when building certain applications (e.g. perl 5.10.1) that are smart enough to use "getconf" to try determine what flags to use in certain situations. Using getconf to find the right flags is even mentioned in the standards(5) page, but following its advice results in deprecation warnings from the compiler. Not good.
If you run the following code you'll see what I mean:
for f in `man getconf | egrep 'XBS'`; do echo "Checking $f"; getconf "$f"; doneIs this something that I (as a sysadmin for the system) should be able to configure, or is it something that would need to be patched to fix? The man pages for getconf, sysconf, and confstr aren't clear where the values are actually coming from.
So, how should this be fixed?
Thanks,
Tim

Since I'm running regular old Solaris 10, rather than OpenSolaris, I'm skeptical how much help the OpenSolaris developers are truly going to be. I can certainly give it a go, but even if they fix it in OpenSolaris, it might be a very long time before that fix filters into Solaris.Actually, it goes the other way. New features and modification go into the internal Solaris development workspace before they migrate to Open Solaris. The Solaris Express and final releases and Open Solaris releases come from the same source base. Whether a feature or update goes into a Solaris 10 patch depends partly on demand, especially demand from customers with service contracts.
I'm also a little puzzled about the "backwards compatibility" thinking of the compiler developers. In some areas (e.g. C++ and the standard library), what's shipped with the compiler is years and years behind what's current, apparently in the name of "backward compatibility". Yet where compiler flags are concerned, the developers seem to be much more cavalier about deprecating things and making changes that break backward compatibility.We try very hard not to break code or makefiles. Sun (and now Oracle) makes its money from enterprise users. Their code bases last for a long time, and changes are expensive. Changing a line in a makefile or source code file can mean having to re-certify the application.
The change from -xarch to -m specifying the memory model was more abrupt than we would have liked, and in hindsight, was probably not handled very well. We were running into combinatorial explosion of -xarch sub-options due to the increasing number of architectures that the compiler supports. Some option combinations quietly resulted in behavior that you didn't expect. (For example, the combination "*-fast -xarch=v9*"did not give the same result as "*-xarch=v9 -fast*".) Separating memory model from the other considerations made the options easier and more reliable to use.
Don't get me wrong -- I'm all for forward progress with the tool-chain -- I think that the C++ standard library and the defaults should all be brought up to what's current in the industry. Sun Studio 12 update 1 has direct support for Apache stdcxx (if installed in a standard location) in addition to libCstd and STLport. The Apache library will be in the next Open Solaris. When it will be available in a Solaris 10 update has not yet been decided.
I also think adding support for -m32/-m64 was a good move. It just seems to me that if the developers are going to deprecate a large number of flags that the compiler accepts, they should also make certain that the rest of the operating system can handle that change. To me, that means that they need to work with the developers of getconf/confstr() to make certain it knows how to check the compiler version before it emits a particular flag.Only a few options have been deprecated. It's just that they are probably the ones you used most. :-(
More than one compiler version can be installed on a system, and compilers can be installed anywhere. Programmers in medium to large shops typically run compilers installed on a remote server, although they might have other compilers installed locally. If getconf had to guess what compiler you were using, it would often guess wrong. If you have suggestions on how to match up getconf behavior with the compiler you want to use, please post them in an Open Solaris forum.

Warning about improper connections contains no "I understand the risks" options, I can't proceed

I installing Thunderbird on Windows 8.1. I am trying to add 3 accounts. When adding the second account Thunderbird warned about insecure transmission of password. I clicked the "I understand the risks". No problem. When I tried to add my third account, I received the warning again only this time there was no "I understand the risks" option. I can't click 'Done', If I change the setting TB can't find the servers. I am stuck and unable to add my last account.
I have TB installed on my laptop running Windows 7 and had no problems. I am using the same settings as in my version of TB on my laptop. The version of TB is 24.4 on both machines. Of course, the version of TB was younger when I installed on the laptop.
Thanks, in advance, for any advice.
Bill Halteman

I'm stuck too, and don't know what to do.
I am running windows 7.
There is excellent documentation of this problem here - https://bugzilla.mozilla.org/show_bug.cgi?id=812750
Problematically, the warning directs me t FAQ, but when I do a search what I find is that everyone is having the same problem.
Further, my existing accounts now show Connection security - None and Authentication as Password, transmitted insecurely. I suspect I am lucky that my existing accounts still work.

So my airport extreme recently had some nat/dns issue and in the airport utility displayed a warning about it and to correct it. I wasn't sure what to do so i pressed the resolve icon and now my guest network is not working.

Anytime you change networking hardware, it is always a good idea to perform a complete power recycle of your networking components.
I would recommend that you do the following as a minimum:
Power-down the modem, AirPort base station, and computer(s).
Disconnect the AirPort base station from the Internet broadband modem.
While all of the devices are powered-down, perform a "factory default" reset on the base station. This will get it back to its "out-of-the-box" configuration and make setting it up much easier, especially if you use the "Assist me" process within the AirPort Utility. (ref: Resetting an AirPort Base Station or Time Capsule)
After the base station resets, go ahead and power it back down.
Reconnect the AirPort base station to the Internet broadband modem. For the Extreme and Time Capsule, be sure to connect the cable to the base station's WAN (circle-of-dots) port.
Power-up the modem; wait at least 10-15 minutes to allow it adequate time to initialize.
Power-up the AirPort base station; wait at least 5-10 minutes. Note: The AirPort's status light may continue to flash amber after it has intialized. That is because, there may be some additional configuration items necessary, like setting up wireless security, before the overall setup is completed to get a green status.
Power-up your computer(s).
In this basic configuration, the AirPort base station will broadcast an unsecured wireless network with a Network Name (SSID) of Apple Network NNNNNN. Network clients, connected to the base station either by wire or wireless, should now be able to access the Internet through the ISP's modem. Once Internet connectivity has been verified, you can use the AirPort Utility to configure the base station for wireless security and any other desired options. Please post back your results.

Can you help me about change data captures in 10.2.0.3

Hi,
I made research about Change Data Capture and I try to implement it between two databases for two small tables in 10g release 2.MY CDC implementation uses archive logs to replicate data.
Change Data Capture Mode Asynchronous autolog archive mode..It works correctly( except for ddl).Now I have some questions about CDC implementation for large tables.
I have one senario to implement but I do not find exactly how can I do it correctly.
I have one table (name test) that consists of 100 000 000 rows , everyday 1 000 000 transections occurs on this table and I archive the old
data more than one year manually.This table is in the source db.I want to replicate this table by using Change Data Capture to other stage database.
There are some questions about my senario in the following.
1.How can I make the first load operations? (test table has 100 000 000 rows in the source db)
2.In CDC, it uses change table (name test_ch) it consists of extra rows related to opearations for stage table.But, I need the orjinal table (name test) for applicaton works in stage database.How can I move the data from change table (test_ch) to orjinal table (name test) in stage database? (I don't prefer to use view for test table)
3.How can I remove some data from change table(name test_ch) in stage db?It cause problem or not?
4.There is a way to replicate ddl operations between two database?
5. How can I find the last applied log on stage db in CDC?How can I find archive gap between source db and stage db?
6.How can I make the maintanence of change tables in stage db?

Asynchronous CDC uses Streams to generate the change records. Basically, it is a pre-packaged DML Handler that converts the changes into inserts into the change table. You indicated that you want the changes to be written to the original table, which is the default behavior of Streams replication. That is why I recommended that you use Streams directly.

Yes, it is possible to capture changes from a production redo/archive log at another database. This capability is called "downstream" capture in the Streams manuals. You can configure this capability using the MAINTAIN_* procedures in DBMS_STREAMS_ADM package (where * is one of TABLES, SCHEMAS, or GLOBAL depending on the granularity of change capture).

A couple of tips for using these procedures for downstream capture:
 1) Don't forget to set up log shipping to the downstream capture database. Log shipping is setup exactly the same way for Streams as for Data Guard. Instructions can be found in the Streams Replication Administrator's Guide. This configuration has probably already been done as part of your initial CDC setup.
 2) Run the command at the database that will perform the downstream capture. This database can also be the destination (or target) database where the changes are to be applied.
 3) Explicitly define the parameters capture_queue_name and apply_queue_name to be the same queue name. Example:
 capture_queue_name=>'STRMADMIN.STREAMS_QUEUE'
 apply_queue_name=>'STRMADMIN.STREAMS_QUEUE'

Can I stop Windows 7 from warning about security on every linked PDF?

I am working on a project for which I have created one central document (an index) and 120 linked documents. Each document, on every page, has links to the next alphabetical document and back to the central index. This project will be distributed on disc to people with unknown computer platforms.
I am a Mac user, and this works well on my iMac using Adobe Reader. It also works on my ancient Windows XP machine. A tech friend has looked the project over, and he says that on Windows 7 (used by more than half of computer users), every time a document links to a new document, Windows 7 throws up a warning about PDF security hazards. With a large number of documents to open, this could be tiresome.
Is there a way to stop Windows 7 from warning about security on every linked PDF?
This tech person recommends joining all the PDFs into one file (around 50 MB by his estimate), which would require relinking every current link.
Acrobat offers to do the same with its Portfolio, but I'm not fond of the graphic styles offered, and I worry that one large file might be a challenge for older machines.
Any suggestions?

Can you get a screen shot of this error message or at least the exact wording? I suspect the error message is being displayed by Reader/Acrobat and not Windows.

Warning about low disk space on drive E

Hi,
I'm running Windows 7 on a HP Pavilion Elite HPE. My main drive i s C and there is also D (Factory image) and then the HP(E: ) one which is giving the warning about low disk space. When I look at what there is in drive E there is a folder called "my name"-PC with a lot of "Backup Set" folders/files in it, and then there is a folder called WindowsImageBackup and subfolder "my name"-PC.
I know I have to clean out these folders but I ma very insecure as to what I can delete.
I'd be very thankful if you could give me some advice in this matter!
This question was solved.
View Solution.

File History in Windows 7 is an extensive image backup of your drive which will steadily increase over time and needs to be cleared and suggest that you turn the feature off. It is not very efficient.
If you wish to delete this Windows Image Backup file, you should disable the automatic backup feature of Windows.
Click on Start button > Control Panel > System and Maintenance> Backup and Restore.
In the left pane, click on "Turn Off Schedule".
From there you can delete the backup files on your E drive.
I also suggest as an alternative, use Macrium Reflect Free every so often as it is more efficient and reliable. It will make a complete image back up of your entire hard drive to an external hard drive. Don't forget to create a rescue disk.
Go to this site and do a Custom Install:

I personally use the Professional Edition which gives me more flexibility and features.

Question about changing a Snow Leopard Server network settings

We have an Xserve running Mac OS X Server 10.6.8, the primary services running on it are afp, smb, dhcp, dns, jabber and the calendar sever.
Right now we have a router connecting two networks together, 192.168.0.0/24 and 192.168.1.0/24. The Xserve has a static IP address in the 192.168.0.0/24 range.
In order to combine two phone systems into one I am required to combine the above networks, this will involve removing the router and changing the subnet mask on every device from 255.255.255.0 to 255.255.254.0, any device that is currently part of the 192.168.1.0/24 network will also need to have it's router setting changed from 192.168.1.1 to 192.168.0.1. That part should all be easy.
However, this is my first experience expanding a network past a standard class C and am wondering if there is anything I need to watch for on my Snow Leopard Sever.
Specifically I wonder about dhcp settings, right now there are two dhcp servers, the Xserve which provides dhcp for 192.168.0.0/24 and the router that provides dhcp for 192.168.1.0/24. Once the router is removed the Xserve will need to provide dhcp for the entire network.
Looking at the Xserve dhcp configuration right now I have one subnet defined providing addresses 192.168.0.5 to 192.168.0.125.
Can I simply click the + to add another subnet and add for instance a range of 192.168.1.5 to 192.168.1.125?
Will it simply give out all of the ip addresses in the first range and then start with the 2nd? Or do I need to find a single range of ip addresses large enough to meet my needs? (e.g. 192.168.1.5 to 192.168.1.225 or something).
Is there anythign else to watch for after making this type of network setting change?
Thanks in advance.

Thank you for your very detailed reply.
I understand the problems that can arise using 192.168.0.x and 192.168.1.x and if this were a new project I would definitely switch to something else, however in this case we have been using these ip ranges for years (they were in use here long before I started) and I don't want to have to redo all of my dns settings at the same time I make these other changes so I'm going to stick with the same ip's we are using at least for now. Anyone here needing vpn access has already dealt with this issue but we have very few vpn users so it has not been a major problem for us to date.
My biggest question is about increasing the size of the dhcp pool. For instance, after I change all the network settings and set up a /23 network is it possible to have a single dhcp pool that includes some ip's in the 192.168.0.x range and others in the 192.168.1.x range? I guess what I am asking is when I am in Server Admin and click on DHCP one of the tabs across the top is "Subnets". Right now there is a single "subnet" configured that provides addresses from 192.168.0.5 to 192.168.0.125.
Ideally I would like one dhcp pool that provides ip's in the range of 192.168.0.5 to 192.168.0.125 and then if all of those are used up, moves to 192.168.1.5 to 192.168.1.125. Can I do that by simply adding another "Subnet" so there are two? Or do I have to find one larger single range? (e.g. 192.168.1.5 to 192.168.1.225?) You may have already answered this indicating I have to have a single larger range but I just want to be sure.
The parts about changing subnet masks, and routers and all that I think I have a pretty good understanding of.
Your last paragraph is something I have been worried about, I do have a feeling that after making this change there will probably be unforseen issues that will need to be resolved, I'm just hoping it is not too many. For the scope of this thread I will just focus on issues that may arise with the Snow Leopard Server however.
Again, thank you for your help.
