I am running a 10gR2 rac database on 11gR2 grid.
I like to switch from a rac to a standalone database including downgrading the license to standard edition one. Actually SE1 is not an install option for 10g.
Would it be enough to reconfigure the 2nd rac node ?
I have started to migrate 11.2.0.3 database from Enterprise to Standard edition with expdp/impdp (RHEL box). I've managed to transfer database without any problem (ok i had little difficulties with bitmap indexes but never mind).
But now i do not have all public synonyms in place as i already knew. So i have to create sql script and i have found several good ones. My question is do i need to recreate all public synonyms or there is a exceptions in my case because i now have Standard Edition database (old one was Enterprise)?
I am running oracle 11.2.0.2 on AIX 5.3 and when I issue the rman command below to a target DB running 10.2.0.4 I get this error.
$ rman catalog=rman/rman@prod target=sys/sys@prod

What I was trying to do is duplicate my 10.2.0.4 DB and overwrite my 11.2.0.2 DB. Is there a way to downgrade my 11.2.0.2 DB. my 11Gr2 DB I have already set the compatibility parameter to *compatible='11.2.0.2' My 11gr2 is a test DB I don't have a valid backup..
I am checking out licenses. We all know that EE is much more expensive than SE. But many customers do have EE installed - unsure if they need all the features at all. After several years of production, a downgrade is considered 'risky' and we continue to pay the full EE.
How can we check and be sure that a downgrade to SE would not be any problem?
Some checks include:
* partitioning used in user schemas? --> no downgrade to EE
* bitmap indexes in user schemas? --> no downgrade to EE
How can we complete this list, or is there some script to make this easy?
I want to downgrade my database from Oracle 11g (11.2.0.1.0) to Oracle 9i (9.2.0.1.0).
I've done trial of taking export of higher version(Oracle11g) through lower version(Oracle9i) exp utility and trying to import same exp.dmp files into lower version(Oracle9i), but not succeeded and getting some parameter related error.
On Oracle9i database client- Here i'm connecting to Oracle11g via use of 'wbdata.wbh-db1' service

am trying to downgrade my oracle database 10g release 10.2.0.2.0 to 10.2.0.1.0the reason for this is that i had to copy /oracle_home/bin utilities from 10.2.0.1 to 10.2.0.2 because of this most utilities like rman,dbca were not working.
i think i need to downgrade my oracle database 10g release to 10.2.0.1.0 right?i read some oracle documentations of database downgrade instruciting me to
>take full backup of oracle DB
>ORACLE_HOME/bin/emctl stop dbconsole
SQL> STARTUP DOWNGRADE
DROP USER sysman CASCADE;
>SQL> SPOOL downgrade.log

We have Forms application created in Oracle Forms Builder version 9.0.4.0.19. We have done modification in some forms and few forms created using Oracle Forms Builder 10g version 10.1.2.0.2.
Now we need to convert those forms which are around 5 or 6 in number to Oracle Forms 9.
I wanted to downgrade our 2 node RAC 11.2.0.3 to previous version11.2.0.2 on our test environment, so i could prepare to upgrade production later.
I followed oracle documentation and issued
'/u01/app/11.2.0.3/grid/crs/install/rootcrs.pl -downgrade -oldcrshome /u01/app/11.2.0/grid -version 11.2.0.2.0'
and both nodes and manually removed file in upgraded oracle home (rm -r u01/app/11.2.0.3).
This seems to have caused havoc and ASM and srvctl are no working. lsinvemntory lsinventory still poitns to removed oracle 11.2.0.3
I tried to set
export ORACLE_HOME=$ORACLE_HOME
.oraenv
+ASM1
srvctl config ##n
srvctl config
