Hi Basis Expert,
I need your inputs for one of this query
The query is. Can we do oracle 11g software installation in parallel to SAP upgrade when the system is in Downtime phase.
The idea is running SAP upgrade and in parallel running oracle 11g software installation. So that we can reduced the time.
Please share your valuable inputs.
Regards,
Anil Shenoy.
yes, of course.
using different environment during the installation of the new engine, you could install the new oracle home 11 also tomorrow (including the SBP).
infact, before the ./RUNINSTALLER you have to set the environment
setenv ORACLE_HOME /oracle/SID/112_64
setenv ORACLE_HOME_SRC /oracle/SID/102_64
setenv ORACLE_HOME_TGT /oracle/SID/11202
setenv LIBPATH $ORACLE_HOME/lib:$LIBPATH
setenv PATH /oracle/SID/112_64/bin: $PATH

YES, is it possible, BUT.....
1) the machine has already the oracle 11 prerequisite? (run the RUNINSTALLER_CHECK and check it out, may could be necessary a restart of the SO for the kernel parameter or the SO packages)
2) remeber that you can install the oracle 11 software compoent (and the SBP) ALSO NOW (if the runinstaller_check ends OK)
I don't get the point of installing the 11G software during downtime. You can savely install and apply the SBP while your SAP system is up and running, the only downtime is required during the actual upgrade procedure with DBUA. And for that I would strongly recommend you to not run it at the same time you do another upgrade.

No, it is not supported. All the database configurations will be changed collected during the prepare phase which will throw unexpected problems.

Hello Anil,
yes you can do that.
Starting with Oracle 11.2.0.2 - Oracle has introduced the Out-of-place patch set upgrade / installation - so the "old" ORACLE_HOME is not touched. You can even install the new oracle software before the SAP upgrade - it is completely isolated.
