Code changes during database upgrade

Hi,
We are planning to upgrade from 10gR2 to 11gR2 on AIX plateform. Do we need any mandatory changes in existing codes (at sql level or plsql level)so that the the behaviour and the performance of the system remain same after upgrade? Thanks.

Going from 10g to 11g,
I had to make no changes in standard SQL and PL/SQL.
Good upgrade compatibility.
Going from 11g to 10g can cause problems for some things,
like use of PIVOT clause in 11g, not supported in 10g.
But I am wiith the other user, build test box and test away!!

ABAP Code Changes During Upgrade from 4.7C to ECC6

Hi all,
I'm in process of collecting information for our next upgrade.
We are on 4.7C and are planning to upgrade to ECC6. We wanted to know what changes shall be required on ABAP side during this upgrade. e.g. certain ABAP commands which are obselete, few tables , few fucntional modules being obselete.
Any specific functional areas/transcation codes being obselete which in turn would make Uer Exit redudant etc.....
Could somebody please help me out with some info regarding this upgrade? Some links or any hint you can give would help me a lot. (Whether technical or functional..all very welcome!).
Thanks in advance

Hi ,
I too got an error of this type .
The resolution is as follows :
login as user SAP<SID> in the oracle database .
SQL> drop tabel <tablename>;
Restart the upgrade from PARMVNT_SHD phase.

Screen changes during an upgrade

Hi,
Is there any way we can find out the obsolete screens and the screen changes from lower version to higher version during an upgrade.
Thank You.
Regards,
Soumya

Hi
While doing Upgrade You have to aware of all related program like BDC's , Screens related errors and all dictionary related problems.
Some function modules may become obsolete, and some screens will change
and some new fields will be added in the new versions etc.
Also take care of SPAU and SPDD tcodes.
You should be able to know about Unicode concept in sap.
check this
http://www.thespot4sap.com/upgrade_guide_v2.pdf#search=%22upGRADE%20STEPS%20-%20SAP%22
also chk these 2 notes in service.sap.com
Technical Upgrade is only a version upgrade without any functionality changes.
The objects that are needed to be upgraded are:
Includes
Function Groups / Function Modules
Programs / Reports
OSS Notes
SAP Repository Objects
SAP Data Dictionary Objects
Domains, Data Elements
Tables, Structures and Views
Module Pools, Sub Routine pools
BDC Programs
Print Programs
SAP Scripts, Screens
User Exits

Archivelog mode during Database upgrade

I have database that needs to be upgraded (from 8.1.7 to 10.2.0.4) and this database runs in ARCHIVELOG MODE. My question should I turn archivelog mode off during upgrade? Do you see any benefits or issues with that?

Better option to put database in no archivelog mode. Take a backup and then put database in noarchivelog mode.
Log_archive_format will be different in 10g so while enable you may need to change this parameter.

Error while running cr9idata.pl during database upgrade to 11.2.0.2

I am updating the R12 database (11.1.0.7) to 11.2.0.2 following document, <Interoperability Notes EBS R12 with Database 11gR2, 1058763.1>.
In the step 7, to create nls/data/9idata directory...
When I ran the perl script, I get the error as below.
$ perl cr9idata.pl
perl: symbol lookup error: /d01/oracle/SID/db/tech_st/11.2.0/perl/lib/5.10.0/x86_64-linux-thread-multi/auto/Cwd/Cwd.so: undefined symbol: Perl_Istack_sp_ptr
Then, when I tried to check with sqlplus, I now have the error as below.
SQL> connect user/password AS SYSDBA
ERROR:
ORA-12162: TNS:net service name is incorrectly specified
SQL> exit
Then, when I checked some relevant environment, I noticed TNS_ADMIN is empty.
$ echo $ORA_NLS10
/d01/oracle/SID/db/tech_st/11.2.0/nls/data/9idata
$ echo $TNS_ADMIN
$ echo $LD_LIBRARY_PATH
/d01/oracle/SID/db/tech_st/11.2.0/lib
However, if I run the old environment file in old ORACLE_HOME, then the TNS_ADMIN points to the old one (/d01/oracle/SID/db/tech_st/11.1.0/network/admin/SID_host).
And I believe this is not valid...
At the same time, when I check the tnsnames.ora, there are only example/default files under <samples> directory.
$ cd /d01/oracle/SID/db/tech_st/11.2.0/network/admin/
$ ls
samples shrept.lst
How should this be handled to proceed to the next step?
Should I define TNS_ADMIN with the old path...???

Hi;
Please DO NOT use your old oracle_home, as note mention The ORACLE_HOME environment variable points to the new 11.2.0 Oracle home.
Please set below wiht new ORACLE_HOME than try steo 7
- The ORACLE_HOME environment variable points to the new 11.2.0 Oracle home.
- The PATH environment variable includes $ORACLE_HOME/bin and the directory where the new perl executable is located (usually $ORACLE_HOME/perl/bin).
- The LD_LIBRARY_PATH environment variable includes $ORACLE_HOME/lib.
- The PERL5LIB environment variable points to the directories where the new perl libraries are located (usually $ORACLE_HOME/perl/lib/[perl version] and $ORACLE_HOME/perl/lib/site_perl/[perl version])

PERFSTAT schema not upgraded during database upgrade

Hi,
I am currently working in 9i to 10.2.04 upgrades and I am seeing that the perfstat schema is not upgraded properly and I am getting error after upgrade. As temporary solution I am dropping perfstat and configuring statspack again. But for production systems I need the data, Is it possible to fix this perfstat schema error after upgradation.
Thanks
Tamil

After upgrading from 9i to 10.2.0.4 when I take a snapshot I am getting error. And also same for purging.. I am posting here a sample error
SQL> exec statspack.snap
BEGIN statspack.snap; END;
ERROR at line 1:

Upgrade from JDK 1.2.2 to JDK 1.4.2. Any code changes required?

Hi,
We are in the processes of upgrading the JDK versions on servers to JDK 1.4.2 to support other software upgrades.
The JDK versions on each of the servers are at different versions. On one of the servers, the version of JDK is currently at JDK 1.2.2_10. Can somebody please advise me if there would be any code changes required to support this upgrade (such as some methods being depreciated)?
We are also evaluating if we need to upgrade to JDK 1.4.5. In such a case, would there be any code changes required to upgrade from JDK 1.4.1_x to JDK 1.4.5. I assume there wouldn't be any changes for this minor upgrade but just want to confirm.
I would really appreciate an early reply.
Thanks in advance.
Regards,
Vamshi

"1.4.5" - you meant "1.5" ? :)
About deprecations -- you will be warned by the compiler. E.g. "assert", "enum" are keywords and cannot be used as method names.
The rest depends on your application. The more complex it is, the more differences can be encountered. You certainly need to run a test cycle for it with the new platform.
From my experience, I can list some issues that I have read about or have experienced myself:
1) serialization: the algorithm used to calculate the serialVersionUID had some changes between Java versions, due to compiler-added extra methods.
If you don't have serialized instances, or your serialVersionUID is specified explicitly, you are safe.
2) class loading order can be different in different platforms
Once ago I have seen a paper from BEA Systems highlighting some open topics that can arise when migrating between different vendor's JVMs. Probably, it is the one:
http://edocs.bea.com/jrockit/geninfo/devapps/codeprac.html
In my friend's case, there was some class-initialization logic, that behaved differently when class loading order changed.
3) Swing applications can sometimes behave slightly different.
E.g., I observed some changes in focus handling, although minor ones. Fixed with several lines of code.
4) Some libraries can depend on particular J2SE version. E.g. J2EE ones.
E.g. I was not able to run J2EE 1.4 thick client application with JRE 1.5. The j2ee library used by the app either had some dependencies on sun.* classes, or on some protocols (not sure, I don't remember it well).
5) Regression bugs are sometimes encountered. I.e. something that worked, does not work now.
Summary: You need testing.

Group ID Changed During Mac OS X 10.5 Upgrade

I have just discovered that my Group ID was changed during the upgrade from Mac OS X 10.4.10 to Mac OS X 10.5.
Prior to upgrading, my User ID was mcc and my Group ID was admin. After upgrading, my User ID remains mcc but my Group ID has been changed to mcc.
Ownership of files in my home directory hierarchy were changed to mcc:mcc. Ownership of files in other directories were not changed and retain the old mcc:admin ownership.
Under "classic" Unix ownerhip rules, I still own the files. However, there seems to be change in ownership policy under Mac OS X 10.5. I cannot make any changes to the files because they are in the "admin" group.
This change has a significant impact on the value of Time Machine as it prevents it from being used to restore system files that have been corrupted. Why is Time Machine backing up all files when there is no mechanism for restoring files other than those in the user's home directory hierarchy?

Given the above, I would expect to be able to modify, change, or delete any file with ownership set to mcc:admin without using sudo.
Agreed.
Actually, the more interesting question is why was group mcc created.
Yes, perhaps for backwards compatibility if you did an upgrade...
I don't recall it as existing in earlier releases of Mac OS X.
Because I think the opposite is true. Tiger, at least, always created a group for each user, with the same name and with gid=uid. It is Leopard that uses the staff group instead of a unique group per user.

Additional Patch R12 database upgrade

Hi,
I am upgrading my ebs db 10.2.0.4 to 11.2.0.3.
Please suggest the way to approach for additional patch ->13001379
a)I hv unziped patch
b)In README, -> Prerequisites -> 7. cp kutable.xsl rdbms/xml/xsl/.
As per the readme my understanding is - > I hv to copy the file from dir: /13001379/files/rdbms/xml/xsl/kutable.xsl to $ORACLE11g_HOME/rdbms/xml/xsl/ (file already here->update the file)
Then do -> opatch apply
Post step: Will happen during database upgrade
c)If I am wrong, please correct me.
Thanks,
Salim

Database upgrade to 10.2.0.4 error - oracle RAC status showing Invalid

Hi all,
I am getting this error during database upgrade to 10.2.0.4 error - "oracle real application clusters status invalid. "
I am getting the above error after running catupgrd
and checking the status SELECT COMP_NAME, VERSION, STATUS FROM SYS.DBA_REGISTRY;
This is not a RAC database and this is the only components which shows INVALID.
Is it normal? Please advice me the action/steps to take to rectify ASAP as it is urgent ... Thanks & Regards, Deepak Gupta

Probably database was 9i and it was upgraded to 10g?
It can be normal situation.
Please check metalink note 312071.1
If database is not rac, then simply ignore this status as workaround is quite difficult and definetely it's not worth to go for it.

During R12 upgrade adworker for patch u6678700.drv fails for afopp002.sql

Hi Experts,
During R12.1.1 upgrade from 11.5.10.2 adworker for patch u6678700.drv fails for afopp002.sql
The exact error being faced is
sqlplus -s APPS/***** @/u03/oracle/CRP1PROD/apps/apps_st/appl/fnd/12.0.0/patch/115/sql/afopp002.sql &un_fnd &pw_fnd
Connected.
declare
ERROR at line 1:
ORA-20000: Oracle Error Mkr1= -24018 - ORA-24018: STOP_QUEUE on
APPLSYS.FND_CP_GSM_OPP_AQ failed, outstanding transactions found
ORA-06512: at line 15
I even tried restarting the worker,bounced the database and even tried running u03/oracle/CRP1PROD/apps/apps_st/appl/fnd/12.0.0/patch/115/sql/afopp002.sql manually which hangs for indefinitely.
Any suggestion.

Hi Srini,
Let me walk you through briefly regarding the upgrade process:
Initially the existing instance was 11.5.10.2 with 9.2.0.6 database.Last year the database was upgraded to 11.2.0.1 and configured with 11.5.10.2
However the 11g database upgrade steps specifically for EBS 11i(interoperatibility notes for 11i with 11g database) was not followed properly.
And one of the major key issue identified was the 11g Example CD was not installed on top of 11g software during database upgrade.Which is the pre-req for 11g upgrade in EBS
And as per my experience it creates issues during R12 upgrade (patch u6678700) and giving errors pertaining to oracle text error.
SR was raised for the same and was suggested, since there is no other option kindly install the Oracle 11g software and on top of that 11g Example CD and map the 11g database and go ahead with the R12 upgrade.
Now coming back to the core issue being faced, Pre-req followed properly.No errors in alert logs.
Can missing the Example CD installtion be the issue?

Aman Vats

Best practice to secure database during patching/upgrade-Vault disabled

I have a highly confidential system and to protect the data in the DB, I intend to use Oracle Vault. In my company, we have centralized services and therefore, the oracle Unix owner and sysdba are owned by this group, not the application dba that "knows" the system (me).
The problem I have is what would be the best way to protect my data from the sysdba user during the window that Vault is disabled?
I thougth maybe I could un-mount and file protect the tablespace from the Unix oracle user during the upgrade process, but the tablespace could be outdated when I remount it after the patch. I am not sure how I might patch it seperatley. I am thinking I might export and drop the schema during the patching, then load it back in when vault is enabled again. This will work for a year or so, but I envision the databases getting too large to do this efficiently.
Does anyone have any thoughts on how I might protect the data in this scenario?
Edited by: user4714217 on Oct 20, 2008 11:06 AM for clarity

Hi,
I did not understood your question properly, but the thing which I understood is like you do not want any other user to access the database when your security vault is disabled.
At that time you can
1) Start the database in restrict mode (only a sysdba can do it).
2) Change the password/lock the user till the time your patching activity is going (any user with dba role can do it, so might be not so useful)

Change DB name/ instance name during an UPGRADE ?

Is it possible to change the database name and the instance name during an UPGRADE (from 9i to 10g for instance) ? If is possible, how ?
Thanks,
D.

Two Options:
1. Change the name in 9i, then Upgrade to 10g
2. Upgrade to 10g, then change the name in 10g
There is no automatic way to do it during upgrade.
