Refresh Discoverer with database changes

Hi,
New to Oracle.
Is there a way to refresh any custom/complex folders created using the Discoverer Admin with the latest database table information, like if the table name was re-named or column was re-named without having to do this manually?
Like if the table was re-named from ITEMS to A_ITEMS.
Thanks.

Hi,
Right-Click the folder and select "Refresh"(This applies only if the column names or
where condition is changed in the query).
But if the table name is changed, you have to change manually in the Admin folder.
Thanks

Installing Discoverer with Database Version Oracle 10g Express Edition

Hello,
Is it possilbe to install Discoverer with database version Oracle 10g Express Edition? I have Oracle Fusion Middleware 11.1.1.1.0 on my Windows XP machine as well. If so, can someone please provide me a link to the Discoverer download.
Regards,
Kelly

Note that the Personal Edition of the database is 'the most powerful' version, in that it contains all features and options of the Enterprise Edition (expect RAC and Enterprise Manager packs)
As such, the Personal Edition, at a mere USD$400-500 is one of the most cost effective for-fee products that Oracle has in it's inventory. It is targeted at the developer. And it comes with the complete set of Sample Data, whereas XE has a very limited subset (since it does not support all functionality).
Express Edition is indeed free, but it is not supported, and can not be patched. OTOH it does have a lighter footprint.
Again, I am not sure whether Disco 11g is compatible with Express Edition. (It's on my schedule for December ...)

How to Synchronize an association with Database Changes

Hi,
I was wondering if someone has any ideas about how to manage FK changes with the BC associations. In general my questions center around tooling support for re-factoring associations and syncing them with db changes. I have read the following but all these discuss entity attribute related changes which are simple to manage.
http://download.oracle.com/docs/cd/E14571_01/web.1111/b31974/bcentities.htm#ADFFD169
http://jdeveloperfaq.blogspot.com/2010/02/faq-15-how-to-synchronize-adf-entity.html
Re: How to manage ADF BC components in the case of datamodel changes
I have 4 use cases.
Case 1: When an association is added to the db, how does one bring it to the BC layer.
Case 2: Deletion of an association from db is easy to manage because once it exists in bc layer, it can be treated as a valid one at the model later regardless of its existence on the db.
Case 3: When an association is modeled in BC layer and a corresponding FK does not exist in DB. How does one turn that association into a physical FK in the db if one wants to install a FK. What is the naming convention for installing such a db FK constraint that can sync easily with tooling. I understand that it is not necessary to have a physical FK as the BC layer will take care of enforcing the relationship. But my requirement is that first the modeling at bc layer can go on and then the constraint can be implemented at a later date.
Case 4: When a FK is renamed in db how does one reconcile that with a previously created association at the model layer based on an old fk with a different name.
Thanks,

The synchronize with DB will pick up new FK defined in the DB and will suggest to add them to your ADF BC layer.
You can also generate DB objects from your ADF BC layer.
Drag your ADF BC into an ADF BC diagram, select all of them, right click and select Generate Business Object->Database Objects
This will create the objects in the DB - note though that this will override your DB objects.

How to perform up high availability upgrade with database changes?

Hi,
Can someone point me to pertinent documentation for performing live upgrades? Specifically I'm looking for best practice for setting up and attaining High Availability especially during application upgrades which have db changes.
Thanks in advance,
Rich

Hi,
For internal clients, yes, your requirement can be met by setting the autodiscover site affinity by using the “AutoDiscoverSiteScope” parameter in Set-ClientAccessServer command:
https://technet.microsoft.com/zh-cn/library/bb125157(v=exchg.150).aspx
For external clients, I am afraid “No” because the “autodiscover.domain.com” only points to one CAS server.

How to use the database change notification event with an AppModule Child ?

hi,
I try to do the same stuff that this "How To" : [http://niallcblogs.blogspot.com/2009/06/auto-refreshing-adf-chart-objects-in.html].
This example works fine, but I want an Application Module Root which contains the Application Module which contains the VO where there is the method processDatabaseChangeNotification.
I have trying all the configuration possible of AppModuleRoot and AppModuleChild: Shared/Local, Local/Shared and even Local/Local ... but nothing works ...
Can you tell me if possible, and if so ... how?
thanks !
(I use jdev11g)

I don't find my reponse in the documentation....
I have an AM Child in an AM Root like that :
<AppModuleUsage
Name="AppModuleChild"
FullName="model.AppModuleChild"
ConfigurationName="model.AppModuleChildShared"
SharedScope="2" />
My AM Root is Shared in the file "DataBinding.cpx" :
<BC4JDataControl id="AppModuleRootDataControl" Package="model"
FactoryClass="oracle.adf.model.bc4j.DataControlFactoryImpl"
SupportsTransactions="true" SupportsFindMode="true"
SupportsRangesize="true" SupportsResetState="true"
SupportsSortCollection="true"
Configuration="AppModuleRootShared" syncMode="Immediate"
xmlns="http://xmlns.oracle.com/adfm/datacontrol"/>
... and the database change event notification don't work... I don't understand !

Firefox always hangs. Spinning Beach Ball appears. Must Force Quit repeatedly. Have re-installed and refreshed with no change. How to fix?

Every time firefox is launched, the spinning beach ball appears, sometimes immediately, sometimes within a minute or two, every time. Must force quit. I have re-installed Firefox and also have refreshed with no change. Unless this is fixed, Firefox is unusable. I am running OSX 10.9.5 on a 17" MacBook Pro.
I cannot access any information through Firefox, because t always hangs.

Could you test in Firefox's Safe Mode? That's a standard diagnostic tool to deactivate extensions and some advanced features of Firefox. More info: [[Troubleshoot Firefox issues using Safe Mode]].
''If Firefox is not running:'' Hold down the option key when starting Firefox.
''If Firefox is running:'' You can restart Firefox in Safe Mode using either:
* "3-bar" menu button > "?" button > Restart with Add-ons Disabled
* Help menu > Restart with Add-ons Disabled
and OK the restart.
''Both scenarios:'' A small dialog should appear. Click "Start in Safe Mode" (''not'' Refresh).
Any less crashy?

Hi Paulbin,
Do you want to supply a function-pointer to a DLL so it can call[back] your VI? Here's how it can be done with .NET, though, that solution requires a C compiler. A single "VI_to_function-reference" utility could handle all cases where the callback passes no parameters. Maybe someday somebody will share that dll.
Did you know that LabVIEW can use Events for some COM-signals change? See pic. (Note: DTR is not listed - - )
Another question is another function's prototype is WORD SetTestType(WORD comHandle, bool type1, bool type2, bool type3), I tried to use a boolean control and a Boolean to (0,1) node in labVIEW to pass parameters to CLF, I config the bool input value as U8(according to C++ bool type) and U32(according to WIN32 BOOL type), it dose not help, when I execute the VI, LabVIEW will be disappeare, it seems to be closed, I must start it again.
Could someone has similar experience on this points?
It's easy to crash LabVIEW misusing CLF - maybe there's another reason for the crash besides bool mis-match(?) Do you know which "Calling convention" is required? What type is comHandle? (where does comHandle come from?)
Cheers!

Cube refresh fails with an error below

Hi,
We are experiencing this problem below during planning application database refresh. We have been refreshing the database everyday, but all of a sudden the below error is appearing in log. The error is something like below:
Cube refresh failed with error: java.rmi.UnmarshalException: error unmarshalling return; nested exception is:
java.io.EOFException
When the database refresh is done from workspace manually, the database refresh is happening successfully. But when triggered from unix script, its throwing the above error.
Is it related to some provisioning related issue for which user has been removed from MSAD?? Please help me out on this.
Thanks,

Using Database Change Notification instead of After Insert Trigger

Hello guys! I have an after insert trigger that calls a procedure, which in turn is doing an update or insert on another table. Due to mutating table errors I declared the trigger and procedure as autonomously transactional. The problem is, that old values of my main tables are inserted into the subtable since the after insert/update trigger is fired before the commit.
My question is how can I solve that and how could I use the change notification package to call my procedure? I now that this notification is only started after a DML/DDL action has been commited on a table.
If you could show me how to carry out the following code with a Database Change Notification I'd be delighted. Furthermore I need to know if it suffices to set up this notification only once or for each client seperately?
Many thanks for your help and expertise!

Sebastian

USER UNABLE TO REFRESH DISCOVERER REPORT IN DISCOVERER DESKTOP 10g

Dear All,
HELP!!!
A new user is unable to refresh discoverer Reports in Desktop. All priviledges have been granted to username in Disco Admin and Usre is able to log into oracle Apps.
On the PC the user logged into someone else can log into Discoverer Desktop and run/refresh discoverer reports without any issues. Hence Ithink neither the PC nor the Discoverer installation is the problem.
Can anyone help? What setup/profile needs to be completed in order for the user to be able to run Disco reports.
Pls note that the following has been completed:
1. Business Areas Assigned to user and his responsibilities.
2. Desktop/Plus Privileges assigned.
3. Allow administration - DISABLED - NOT TICKED
Many thx
DI

Does this person just need to run reports? Or does this person also need to create reports? If the person just needs to run reports, try using Viewer for that person, rather than Desktop. This may be something that you need to log a service request with Oracle to get resolved. Pretty strange that can bring items into a new worksheet, but it won't run. Maybe there is an Oracle applications security issue (since logging in as another person does work)? You may be beating your brains out trying to find a Discoverer problem when it might be an application security problem. Though this is a wild guess on my part.

Help required to fit custom SQL in mapping.xml file for complex queries.
Thanks,
Arun Jadhav.

"Execuite Custom SQL" in DB adapter and you'l get it.
But in this case you'll have to implement your own polling strategy (if you need one).
If you want to use one of the predefined polling strategy you should use "Poll for New or Changed records" and import all the tables you use and connect them in wizard.

Installing EM Grid Control 10.2.0.3 with Database 10.2.0.3 On RHEL4 U3 & U4

Note: This is not an official document, it discusses Oracle Enterprise Manager Grid Control (EMGC) installation on Redhat Linux Update 3 & Update 4 with new database NOT with an existing database. Both OS Updates were installed with FULL PACKAGE INSTALLATION option. Oracle Universal Installer creates the database automatically before creating the EMGC repository.
•     For Linux the base version of the EMGC is 10.2.0.1 and for Windows platform it is 10.2.0.2.
•     The database release is 10.1.0.4 with EMGC 10.2.0.1.
•     When installed it creates three Oracle Homes: 1) db10g (database), 2) oms10g (Oracle Management Service), and 3) agent10g.
Course of Action:
To get to Oracle EMGC 10.2.0.3:
•     Install EMGC 10.2.0.1
 Upgrade Oracle Home oms10g to 10.2.0.3.
 Upgrade Oracle Home agent10g to 10.2.0.3.
To get to Oracle Database 10g 10.2.0.3:
•     Oracle Database 10g 10.1.0.4 will get installed by the OUI automatically
 Upgrade Oracle Database 10g to 10.2.0.1 in new Oracle DB Home.
 Upgrade new Oracle DB Home to 10.2.0.3.
====================================
Installing EM Grid Control 10.2.0.1:
====================================
To install EMGC 10.2.0.1 download all the three files: Linux_Grid_Control_full_102010_disk1.zip, Linux_Grid_Control_full_102010_disk2.zip, Linux_Grid_Control_full_102010_disk3.zip from http://www.oracle.com/technology/software/products/oem/htdocs/linuxsoft.html.
If you have unzipped all the downloaded zip files in separate directories then the very first error message slammed at your face after starting the installation will be something like “OUI-10133: Invalid Staging Area. There Area No Top Level Components”. All you have to do is to unzip all the three files in the single directory (Metalink 395030.1).
After unzipping all the files in the same directory follow the steps that are given on the follow URL.
http://www.oracle.com/technology/obe/obe10gemgc_10202/install/install.htm
BUT the problem is that you will be punched with few other error messages during the installation that will terminate the installation. The WORKAROUND is given below.
There are three stages of the installation by OUI:
1.     Installation of EM Repository Database 10.2.0.1.
2.     Installation of EM Grid Console 10.2.0.1.
3.     Installation of Agent 10.2.0.1.
The first stage completes without any problem and on the OUI you will see: Oracle Enterprise Manager Repository Database 10.2.0.1.0 installed. While installing the Grid Console, during copying files for "Oracle Application Server 10g 10.1.2.0.2" at 90% OUI will pop up an error message "An error occurred during runtime." You will see lines similar to the following lines in the installation log files.

Problem:
There is a bug which is still being worked on by the DEV : Bug 5203165 : Abstract: CANNOT EXECUTE ../oms10g/bin/OracleAs_Relink_Patch.sh AT INSTALL
Note that this is an unpublished bug, not viewable via Metalink. The bug apparently occurs only on RHEL4 (32bit) Update 2 and Update 3 (I faced the same thing in Update 4 as well).
Workaround:
•     Leave the error message as it is and change the execution permission of the script OracleAS_Relink_Patch.sh.
$ chmod +x /u01/app/oracle/product/10.2.0/oms10g/bin/OracleAS_Relink_Patch.sh
•     Now press Retry on the error message pop up window. The installation will resume.
On the same stage while linking at 90% one another error message will pop up “Error in invoking target 'install' of makefile '/u01/app/oracle/product/10.2.0/oms10g/sqlplus/lib/ins_sqlplus.mk'”.
Problem:
Hitting bug : 5203194 :Abstract: RELINK FAILS ON 10.2 GC INSTALL -LIBCLNTSH.SO: UNDEFINED REFERENCE TO NNFGTABLE
Bug is not published in Metalink. As per the description: Installing 10.2.0.2 Grid Control on RHEL4 Update 2 or Update 3 (I faced the same thing in Update 4 as well). This generates an error in the linking phase. The error is generated while attempting to relink sqlplus.
Workaround:
•     Stop installation of all components.
•     Restart the installation and pick the option to resume the installation.
•     This allows the installation to complete.
If by any chance you press continue instead of stopping the installation you should get ready for the garbage OUI is going to throw at you:
Error in invoking target 'install' of makefile '/u01/app/oracle/product/10.2.0/oms10g/network/lib/ins_net_client.mk'

Upgrading EM Grid Control 10.2.0.1 to 10.2.0.3:
====================================
I hope after installing EMGC 10.2.0.1 you are still intending to upgrade it..... :-D Now for that download GridControl_10.2.0.3_Linux.zip from http://www.oracle.com/technology/software/products/oem/htdocs/linuxsoft.html and follow the README.txt file included with the upgrade patch. Before starting the upgrade you will probably have to apply a patch (4329444) on the existing database (10.1.0.4). Anyway, its one of the prereq that you have to complete.
For upgrade follow the steps given on the following URL.
http://www.oracle.com/technology/obe/obe10gemgc_10203/patching/patching.htm
•     Keep one thing in mind that you will have to apply the above mentioned patch twice. Once for oms10g home and once for agent10g home.
•     Stop all the EMGC related services.
•     When applying the patch to a particular home change the ORACLE_HOME to that home. E.g. when applying the patch on the oms10g home:
ORACLE_HOME=$ORACLE_BASE/product/10.2.0/oms10g
and for agent10g home:
ORACLE_HOME=$ORACLE_BASE/product/10.2.0/agent10g
====================================
Upgrading Database from 10.1.0.4 to 10.2.0.1:
====================================
Download the file 10201_database_linux32.zip from http://www.oracle.com/technology/software/products/database/oracle10g/htdocs/10201linuxsoft.html.
•     Shutdown all the EMGC related services, the listener, and the database.
•     Start the installation of 10.2.0.1.
•     Since 10.2.0.1 is a base release that is why you cannot install it in the existing Oracle Home i.e. in db10g. You have to define a separate Oracle Home for the new installation say db10gR2.
•     During the installation it will ask you to upgrade the existing database 10.1.0.4 to 10.2.0.1, click YES.
•     Hopefully the installation will go just fine.
====================================
Upgrading Database from 10.2.0.1 to 10.2.0.3:
====================================
Download the file p5337014_10203_LINUX.zip from http://metalink.oracle.com.
•     Shutdown all the EMGC related services, the listener, and the database.
•     Start the installation of 10.2.0.3.
•     During installation it will ask for the Oracle Home, give the new Oracle Database Home i.e. db10gR2 and proceed.
•     Hopefully the installation will go just fine.
•     Start the database, listener, and all the EM GC related services:
o     $ORACLE_HOME/../oms10g/bin/emctl start em
o     $ORACLE_HOME/../agent10g/bin/emctl start agent
o     $ORACLE_HOME/../oms10g/opmn/bin/opmnctl startall
•     Try accessing the EMGC through the browser http://xyz.abc.com:4889/em
•     You will see two Oracle databases in the EMGC, the old one, 10.1.0.4 and the new one 10.2.0.3. Don’t worry it will not bother you at all. It will only occupy a GB or so. Though, you can remove it through OUI.
Congratulations!!!! you have now Enterprise Manager Grid Control 10.2.0.3 with Database 10.2.0.3 on RHEL 4 Update 3.
You can repeat the same exercise for RHEL4 Update 4 as well, but during pre-installation checks you will get 1 warning that:
Checking for compat-libstdc++-296-2.96-132.7.2; found Not found. Failed <<<<
Checking for libstdc++devel-3.4.3-22.1; found Not found. Failed <<<<
Checking for openmotif-21-2.1.30-11; found openmotif-2.2.3-10.RHEL4.5. Failed <<<<
Actually, these packages are already there in the OS but the higher versions. It is evident from the above messages that first it “founds” the package but due to the version conflict it says that “Not found”. All you have to do is click on the check box next to warning, it will change to User Verified or something. Now press Next and follow the same steps that we followed for Update 3.

The quicker way is to use sofware only method to install 10204 oms and dirctly use 10203 datbase directly as a oms repository.

Best practice for tracking database changes...?

Dear Oracle gurus,
I'm still relatively new to database administrating, and recently I ran into a situation which I'm not sure if there's some text-book scenario analysis or practice.
I find it hard to track all the database changes across different servers. Our company develop software that uses the Oracle database, so we have development and test servers set up here and there, with really minimal control on them. Problem arises when we make rapid design changes to our system, which required multiple and rapid changes to the databases. I find it really hard to keep track of everything, because sometimes I can't patch some server because of people still using it for development/testing/investigation/etc.
So, is there some kind of good practices for tracking database changes (which we even write patches for), monitoring schema modifications, or maybe even versioning database objects? I've tried to find some information but I think I did not look in the right places or ask the right questions.
Any help is appreciated.
Best regards,
Peter Tung

The first thing I would start with is:
Find a version control system that will allow you to store files and version them (PVCS for example). You could for example, store all the sql scripts. Whenever a change is needed, the user could check the program out from the version control tool and make changes and check it back in. Besides sql scripts, you could also store binary files or any type of source code files in a version control system. This would at least put some things in order. In a version control system, you could associate a number or a string with all the files within a patch.
