Importing Statistics - Oracle 11g upgrade

Hi,
We are in the middle for planning for migration of oracle 9.2.0.8 database hosted in HP-UX to oracle 11gR2 to Linix. The database size is 1 TB ( 400GB of table data & 600GB of index data).
Please let us know whether we can use the option of import/export the statistics from the Oraclr 9i to oradle 11g database. The database is highly OLTP/Batch. Will it be any Query performance problem due to the statistics import from oracle 9i to oracle 11g.
Any suggestion are welcome and let me know if you need any more information.
thanks,
Mahesh

Hello,
Please let us know whether we can use the option of import/export the statistics from the Oraclr 9i to oradle 11g databaseIf I were you, when the data are imported to the 11g Database I would refresh the Statistics by using the dbms_stats Package.
Then, you can test the most common queries on the new Database. If some perfomance troubles appear, you can use classical tools (Statspack, Explain Plan, TKPROF,...) or some useful tools you have in 11g as SQL Tuning Advisor or SQL Access Advisor :

http://download.oracle.com/docs/cd/E11882_01/server.112/e16638/advisor.htm#PFGRF008
Hope this help.
Best regards,

Oracle 11g upgrade: How to update stale statistics for sys and sysman?

Hi,
I am in the process of testing Oracle 11g upgrade from Oracle 10.2.0.3. I have run utlu111i.sql on the 10g database.
The utility utlu111i.sql reports about the stale statistics for SYS and SYSMAN components.
I executed dbms_stats.gather_dictionary_stats; dbms_stats.gather_schema_stats('SYS'); and dbms_stats.gather_schema_stats('SYSMAN');
After that the utlu111i.sql still reports the stale statistics for sys and sysman. Does anyone know how to get rid off this warning successfully?
Thanks,
Sreekanth

Does anyone know how to get rid off this warning successfully?Just ignore the warnings. Check The Utlu111i.Sql Pre-Upgrade Script Reports Stale Sys Statistics - 803774.1 from Metalink.

Oracle 11g upgrade issue

Dear Friends,
We are running oracle 10.2.0.4 and HP-UX 11i v3. We have upgraded oracle 11g. Upgrade has completed successfully and after that We have installed the Oracle 11g client.
Now we are trying to execute command sqlplus "/ as sysdba" but it is giving the error message as below.
jkepdvr:oraepd 1> sqlplus "/ as sysdba"
/usr/lib/hpux64/dld.so: Unable to find library 'libsqlplus.so'.
Killed
Regards
Ganesh Datt Tiwari

Hi Ganesh,
Are you able to execute the same command with the ora<sid> user . If
yes then could you please check if the environment variables for the
<sid> adm has been set properly .
Please refer the below notes -:
Note 96858: Environment variables (UNIX)
Note 602843 : Environment settings for R/3/Oracle on UNIX
If the issue is not solved please provide these outputs
Log in as <SID>adm user and please provide me the output of the
following -:
whoami
env > environment_var_SID_ADM.txt
Again log in as ORA<SID> user and do the same -:
whoami
env > environment_var_ORA_SID.txt
Please upload both the files to the message-:
environment_var_SID_ADM.txt
environment_var_ORA_SID.txt
These files would be located in the present working directory from
where the env command was executed.
The permission of sqlplus -:
ls -lrt $ORACLE_HOME/bin/sqlplus
With the <SID>adm user , check the following command -:
ls -alt $ORACLE_HOME/lib
Do you encounter any permission issue ?
Please upload the output of the following commands executed as <sid>adm
to this message:
- cat /etc/group
- cat /etc/passwd
- ls -ltr $ORACLE_HOME/bin/oracle
- ldd /usr/sap/PRD/SYS/exe/run/dboraslib.so
I hope it helps.

Oracle 11g upgrade in AIX 6.1 with HACMP

Hi Friends,
As i have two Power Servers running in AIX 6.1 with oracle 10g in HACMP in which SAP application is running.
The one is standalone Database and other is central Instance.
I have done the 11g upgrades successfully in my DEV and QAS servers which are non-cluster Environment.
Now i want to do the same upgrade in PRD which is in HACMP.
Please let me know what are the areas should i concentrate specially for cluster environment servers.
Thanks,

03113 end-of-file on communication channel | Oracle 11g Upgrade

Hi,
Whilst upgrading our DEV system from 10.2.0.4 to 11.2.0.1 using DBUA
with a powershell script , the upgraded failed with the error "ORA-
03113 end-of-file on communication channel" during the "Upgrading
Oracle Server" section.
The oracle 11g service is created but it cannot start.
The oradim.log reports
03113 end-of-file on communication channel also.
The alert log just show the database tries to start and reports the parameters from the pfile it's using but then stops without any error message.
All the pre-upgrade tasks are done and there was no errors. This is on Windows 64bit 2003.
The server is vmware , not sure if this could be an issue.
It was possible to roll back using the dbua script and bring the system back up with 10g.
Anyone come across a similar issue ?
Thanks
Jim

ORA-3113 are well known output from a connection to database lost of a reason.
Oracle says this reconnect and try again as solution.
If you got the same error on the same place /job, investigate the script/job.

Oracle 11g upgrade issues

Hello :
We recently migrated our database from 9.2.07 (RBO) to 11.2.0.1 (CBO) ( Solaris 10 Sparc 64 bit ). Ever since the migration happened we are experiencing the following issues:
1. Execution plans are very costly. ( Please note that we moved from RBO to CBO )
2. High Gets / Reads
3. High CPU Utilization
4. High waits on 'DB FILE SEQUENTIAL READ'
5. This situation is vitually killing all our applications performance.
I know that oracle 11g explicitly does not support RULE based optimizer , but is there any parameters that can force it go the RBO way.
I would really appreciate your help.

Oracle 11g upgrade prerequisite fails for all the values

Hi,
We have planned Oracle upgrade from 10.2.0.4 to 11.2.0.2. We have
followed the upgrade guide Database Upgrade Guide "Upgrade to Oracle Database 11g Release 2 (11.2): UNIX". Our OS versionis HP-UX ia64 B.11.31. According to the upgrade guide we have set all the environment vairables. And started the Oracle 11.2.0.2 software installation prerequisite with the command " ./RUNINSTALLER -check " The result of the prerequisite check was giving the all the parameters are failed. But the parameters like Physical memory, orasid user also showing failed eventhough we are having 16 GB of physical memory & we logged on
with orasid it self and all the parameters are showing failed.
We have check the Oracle metalink note#169706.1, According to the note we have valid version of HP-UX 11.31 and some patches are already installed and some of them are not installed. But the prerequisite check showing all the patches are in failed state irrespective of some installed patches.

Hi Prabhakar,
>> DBUA was disconnected with error Ora 1092 Oracle instance terminated.
But, as far as I understand that you didn't completed DB upgrade succesfully. Under this circumstance, you shouldn't change ORACLE_HOME variable to 11.2.0.2. I suggest you that complete Oracle upgrade (restart DBUA) and do not execute upgrade procedures, manually.

Error 1114 on XP+SP2, Oracle 11g

My environment:
Server: Linux, Oracle Enterprise 5.3. Oracle 11g, upgrade to 11.07 by a package download from web site, name as p6890831_111070_Linux-x86-64.zip.
Client: XP+SP2, 11.06, upgrade to 11.07 b a package download from web site, name as p6890831_111070_Win32. I don't know the original zip name, just can see the folder name from our file server.
There are 6 clients at our lab, all them are OK, until I install a new OS(English) XP+SP2 in D disk at 2 clients. Both the two clients fail to create an ODBC connection now, but others still are OK (the left 4 clients OS is same with the 2 clients, that's say, XP(En)+SP2). I still can connect to my Oracle Serve by SQL Developer at the 2 client now, just ODBC driver doesn't work.
I can see an ODBC Driver from Control Panel->Administrative Tools->Data Sources(ODBC), as the following,
Oracle in OraOdac11g_home1 11.01.00.07
but when I try to add a DSN, I can see an error said,
The setup routines for the Oracle in instantclient11_1 ODBC driver could not be loaded due to system error code 126.
When Connect to Oracle from my application software, I can see a messag said
Error Cannot Load Resource File sqresus.dll, after click OK button, another error message pop up,
ERROR[IM003] Specified driver could not be loaded due to system error 1114 (Oracle in OraOdac11g_home1).
I have download the latest ODBC Driver from web site, but these files date and size in the package are same with existing. Anyway, I install it, then I can see a new ODBC driver from Data Sources(ODBC), name as
Oracle in instantclient11_1 11.01.00.07
after restart, I try to create a DSN, still failed.
By checking HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBCINST.INI\, I can see both driver and setup value are
"D:\\app\\Administrator\\product\\11.1.0\\client_1\\SQORA32.DLL"
it is my installation path, and I can see the DLL under the directory.
By the way, current PATH is
PATH=D:\app\Administrator\product\11.1.0\client_1;D:\app\Administrator\product\11.1.0\client_1\bin;D:\WINDOWS\system32;D:\WINDOWS;D:\WINDOWS\System32\Wbem;%ORACLE_HOME%\bin;%ORACLE_HOME%\bin
anyone can give me a kindly help?
Thanks in advance.

My environment:
Server: Linux, Oracle Enterprise 5.3. Oracle 11g, upgrade to 11.07 by a package download from web site, name as p6890831_111070_Linux-x86-64.zip.
Client: XP+SP2, 11.06, upgrade to 11.07 b a package download from web site, name as p6890831_111070_Win32. I don't know the original zip name, just can see the folder name from our file server.
There are 6 clients at our lab, all them are OK, until I install a new OS(English) XP+SP2 in D disk at 2 clients. Both the two clients fail to create an ODBC connection now, but others still are OK (the left 4 clients OS is same with the 2 clients, that's say, XP(En)+SP2). I still can connect to my Oracle Serve by SQL Developer at the 2 client now, just ODBC driver doesn't work.
I can see an ODBC Driver from Control Panel->Administrative Tools->Data Sources(ODBC), as the following,
Oracle in OraOdac11g_home1 11.01.00.07
but when I try to add a DSN, I can see an error said,
The setup routines for the Oracle in instantclient11_1 ODBC driver could not be loaded due to system error code 126.
When Connect to Oracle from my application software, I can see a messag said
Error Cannot Load Resource File sqresus.dll, after click OK button, another error message pop up,
ERROR[IM003] Specified driver could not be loaded due to system error 1114 (Oracle in OraOdac11g_home1).

Oracle 8i*/9i* to Oracle 11g

Hi Experts,
I have few exp dumps from earlier version of oracle 8i & 9i, now i wanted to import in oracle 11g.
So will you please tell me how to do or please provide some URLs/Docs to refer ?
I have read MOS Doc 132904.1 do from where i can get earlier exp/imp client and how to use on oracle 11g DB server ?
Thank you

When importing older dump files you don't have to use an old client. You can just use the imp client that came with your database.
imp help=y
will help you with some of the syntax.

Oracle 11G - Oracle AWR export import Query Statistics.

I have Oracle 11G, i have seen the sql statements through Historical AWR option from Top Activites in performance tab. Can i export all AWR query statistics from production machine so that i can analyze all logs after importing it.
How can i know all statistical sql ( information ) and performace of production machine ?
any help ?

Hello,
have you checked the DBA_HIST* objects to see what / how was imported?
If the awr export dosn't get the contents of the rolling buffer, then you won't see any session statistics that are only there. If you want to get the contents of the rolling buffer you have to dump the contents of it with :
oradebug setmypid
oradebug dump ashdump 10
and load it into your "test" database.
But before doing this I suggest you read the related metalink documentation if any!!!

DB Upgrade from Oracle 8i to Oracle 11g express edition

Hello,
As per the requirement i have to upgrade some of our application from oracle 8i to oracle 11g express edition on window base platform.
I am using import/export utility to migrate data from oracle 8i database to newly installed oracle 11g XE database. after importing i have tested my application in testing environment. It is working fine.Now I have to do this in production env. before proceeding with it.
please someone let me know what all things i have to keep in mind before execute in prod env. Like all risk,databse backup recovery, or any guidelines need to follow while upgrading lower version of oracle to 11g XE version.
waiting for your valuable inputs.

You might want to consider what other programs interacts with the database; can they still connect to a much newer db server version? Any integrations that need a dry run before going in production? Any other "ad hoc" applications, like excel, running against the db? (you could use listener.log to find out what connects to the db, but a year worth of history might be needed)
Do you have any scripts or other "loosly coupled" stuff that needs review?
Read the New features guides released between versions - there are five or six of them.
Check out the Database Upgrade forum (you could look at this as an upgrade in general from 8.1.x to 11.2), {forum:id=583}. Search the forum for previous related topics and ideas.
