Hi
Is there anyway I can obtain DatabaseMetaData from a (OracleJDBC)RowSet instance ?

Which JDBC drivers support which versions of Oracle database?
JDBC 7.3.4 drivers can talk to RDBMS 7.3.4.
JDBC 8.0.4 drivers can talk to RDBMS 8.0.4 and 7.3.4.
JDBC 8.0.5 drivers can talk to RDBMS 8.0.5, 8.0.4 and 7.3.4.
JDBC 8.0.6 drivers can talk to RDBMS 8.0.6, 8.0.5, 8.0.4 and 7.3.4.
JDBC 8.1.5 drivers can talk to RDBMS 8.1.5, 8.0.6, 8.0.5, 8.0.4 and 7.3.4.
JDBC 8.1.6 drivers can talk to RDBMS 8.1.6, 8.1.5, 8.0.6, 8.0.5, 8.0.4 and 7.3.4.
JDBC 8.1.7 drivers can talk to RDBMS 9.0.1, 8.1.7, 8.1.6, 8.1.5, 8.0.6, 8.0.5, 8.0.4 and 7.3.4. Note that there is a known bug (#1725012) when using JDBC 8.1.7 thin driver to connect to a 9.0.1 RDBMS - applying the JDBC patch solves this known bug.
JDBC 9.0.1 drivers can talk to RDBMS 9.0.1, 8.1.7, 8.1.6, 8.1.5, 8.0.6, 8.0.5, 8.0.4 and 7.3.4.

Can not query from v$instance and v$session from within Pro*C program

Hi there,
We have Oracle 10.2.0.1 enterprise edition running on Linux (Red Hat 4 ES)
Our Pro*C developer tries to query the version from v$instance view and is getting errors when compiling his Pro*C programs.
The related Oracle user account has the SELECT ANY DICTIONARY privilege, so if he tries from the sqlplus, he has no problem querying the v$instance or v$session views. His problem is when he is trying to compile his Pro*C program against the very same Oracle account.
Any help/input is greatly appreciated.

How to make upgrade from application server and not from central instance?

Hello SAP Gurus!
I have SAP ECC release 6.0, and I´m gonna make upgrade to enhancement package 6.06, do you know if Can I make upgrade from application server, but not from central instance?
Thanks.

Hi Victor,
Upgrade process has to execute from the server where message server is running.
So I guess it is not possible to initiate the SAP upgrade from application server.

Error reading job logs of Apps server from Central Instance

Dear Gurus,
We have newly installed system with one CI ( cluster environment) and 2 application Instances.
Systems are recently installed by other team. I am looking into support part after handover.
We have noticed below error while reading failed background job logs from our CI. If suppose any job is failing, we can read respective job log from that application instance but it throws error while reading job log from CI to either of application instance.
I checked /sapmnt/SID/global is shared among all 3 servers and i am successfully able to "Touch a" from applications instances.
Even though i have given "777" permissions to all folders like /sapmnt/SID , /sapmnt/SID/global , /sapmnt/SID/global/400JOB*
I am not able to read job log from CI , for same failed job I can read job log from respective application instance.
Error log :
Error reading job log JOBLGX00080700X39290
Message no. BT167
Diagnosis
The background processing system was unable to read the job log named in the message.
This message suggests that there is a problem with the TEMSE storage system of the SAP system. The TEMSE storage system is a repository for temporary objects, such as job logs and spool requests. Job logs are always stored in the TEMSE as operating system files.
This error occurs if the TEMSE system is not able to find or access the file that contains the text of the job log that you requested. Possible causes for the loss or unavailability of the job log include the following:
Someone deleted the required TEMSE file (from the operating system, not from within the SAP system).
A CRON (or equivalent scheduler) job has deleted the TEMSE file.
The file system in which the TEMSE stores its files is not mounted or is not accessible (NFS problem, disk failure, or similar problem).
The TEMSE reorganize or consistency check functions were used within the SAP system and deleted the job log.
SM21 logs :
Error 2 for write/read access to a file. File = /usr/sap/SID/SYS/global
BP_JOBLOG_SHOW: Failed to display jobs. Reason:
> Error reading job log JOBLGX00080700X39290
Strange this is I can check failed job log on one application instance frfom other application instance but not from CI.
Kindly throw some lights where to check.
Regards,

Hi Shravan,
I guess it is related to permission to /sapmnt/SID/global folder. Please ensure owner is sidadm:sapsys in all the systems viz CI, App servers etc.
Check the mounting options are correctly set with read/write mode.
Hope this helps.

Deepak Kori

Hi,
You have 2 options: use Discoverer Administrator to export/import the workbook; or use Discoverer Desktop to save the workbook to the local drive.
You cannot save a workbook to the local drive using Discoverer Plus.

How to port a Sebel BI Dashboard from one instance to other instance

Hi,
I am in search of find a way to port the Oracle Sebel BI Dash board from one instance to other. When we complete the Dash board in a test instance how can we port it into to production.. is there any way to port the bash board are we need to develop it again in the production.
Thanks
Abdul Hafeez Shaik

Identify the "class=MyStyle" string in the MTML code, and use the Multi-File Find and Replace feature to step through each topic and change the specific instances to "class=MyOtherStyle." (I doubt that you'll want to "Replace All".)
Sorry, there's no silver bullet!
Good luck,
Leon

Need to access the xxi schema in Test Instance How can I create a DB Link please share your ideas and advice me
Advance Thanks
ATIt's still not at all clear, but let me outline what I think you are after
Given a database, ORCL_A
In database ORCL_A we have a schema, HALFTRACK
User HALFTRACK has a table, MYSTUFF
Given a database, ORCL_B
In database ORCL_B we have a user GREENBRASS
User GREENBRASS needs to be able to query the table HALFTRACK.MYSTUFF.
In database ORCL_B, as user GREENBRASS
create database link mylink
connect to halftrack identified by halftracks_pswd
using ORCL_A;
select * from mytable@mylink;The db link defines a connection specification to ORCL_A, using the credentials of a user on ORCL_A. The target of the USING clause in the link definition must be an entry in the tnsames.ora file on the server hosting database ORCL_B.
When querying through the link, database ORCL_B is simply acting as a client to ORCL_A, no different that a sqlplus session on ORACL_B's server. As far as ORCL_A is concerned, ORCL_B is just another client requesting a connection, connecting with the credentials defined in the link definition.

NullPointerException was thrown while extracting a value from an instance

Dear all,
We have got a null point exception during commit call. According to the stack trace shown below, it seems that it is a problem due to instance variable accessor. As we know toplink use reflection to access the instance variable value. I am curious whether the exception we got is related to any class-loader setting. Thanks a lot.

How to import data from one instance to other

Hello all,
I want to modify the data in one dev instance from production instace ,but in same table can any help me out with command how to retreive the data from other instance
example:
I want to change the email address of a person in per_all_people_f table in development instance which has the accurate data in production instance ,I am using the update statement how should I relate them and how to change the value?

You can create one dblink in dev db to Production db with the user/schema the live table belongs. Then you can accesss the live table in dev db.
eg.
Run in Dev db
create database link "live_db.WORLD"
connect to live_user
identified by <pwd>
using 'live_tns_name';
select * from live_table@live_db;
Now the remore live table is available in dev db just as if a local table.
You can play with its data.
But remember to remove the dblink after your work is done.
drop database link live_db; does the work
cheers...

Preserve data from one instance of a workflow to another

Hi all,
I have a quite general question which has been bothering me for a while. It has to do with preserving data between instances of a workflow.
What I need is to preserve some data from one instance of a workflow (as a task in the WF) and then stall the WF for some time - actually it must be stalled until another workflow finishes (this second WF should batch a number of tasks which should be sent (together with all the data) in a form to a different user).
However when this second WF finishes it must thus send a "continue message" to all the instances of the first so that they can continue from their previous states.
I hope you can understand the scenario, otherwise I'll try to elaborate further.
If you could have some hints for what activities in the Workbench I should use and some pointers for pitfalls I would be very greatful.
Thanks in advance
Sincerely
Kim Christensen

Can't you just add your other workflow (child) as as step in the main workflow and set the Invocation Policy to "Wait for Response". This will ensure the main workflow will wait for the end of the child workflow.

Log messages from multiple instances in single file.

Hi!
I have a requirement that i need to log messages from muliple instances of the same object in a file. The new file will be created every day. Likewise, multiple objects might have various instances each.
One class
->multiple instances
-> log message stored in single file.
Note :
I am using the Message driven bean. I need to log from the bean class. JDK 1.3
If u could help me out that would be great.

As long as they are all from the same OS program (a single Java VM), that's OK - you can use Log4j, and use a rotating file logger.
If you point two different virtual machine processes at the same file, one may have it open when the other is trying to rotate it, and your rotation may fail (at best) and/or you may lose the old log (the worst case).
If you need to collect log messages from multiple processes (or even multiple machines), use a syslog-based logger (Log4j has a SyslogAppender) or use Log4j's SocketAppender to write to a log4j-builtin log listener (SocketNode).

Custom Field values are not saved. when MPP imported from another instance.

Hello Mate-
Currently I am merging one small instance (I2) of PWA in our corporate instance(I1). as the corporate instance is huge, we are doing manual merge of groups, securities, users, custom fields etc. also downloading the MPP as xml from I2 and then planned
to publish from I1.
There are few project level custom fields which are being used in MPP. and those fields may have formulas too.
I created same custom field in crporate environment(I1) but while trying to open the projects in our corporate environment(I1), the project custom fields are gone.
Could you please guide me here, I am lost. I can not do a data base migration ans it would override all data from I1 instance so need to do it manually.
Many thanks
Deb
Dev EPM Consultant

Hi
You may not be able to do this as the custom field GUID's are different in both the instance.
You may write a macro to copy the custom field data from one to another one

Dear Experts,
Do you have any idea how to move G/L account balance from one instance SAP to other instance SAP ?
We found that we can use IDoc message type FIDCMT IDoc type FIDCMT01 , but actually we just need to transfer the daily balance nor per transaction?
Please advise should you have any suggestion or other IDoc that can be implemented to this case.
Thank you.

Any ideas, hints, workarounds?
Thanks

Copy Custom toolbar from one instance to another in Project server 2007

Hi,
I am currently using project server 2007. We have a number of instances in our Project server enivoronment. Is it possible to copy customized toolbar from one instance to another? If yes, how?
Thanks in advance

Hi Khaldun,
As per my reply in your previous post, here is a link explaining how to use the organizer:

Basically, just copy the toolbar from the global source instance into a blank project file. Then do the same operation from the blank file containing your toolbar into the destination global model, still using the organizer.
Hope this helps.
