    R12 preinstall cleanup




      We are upgrading oracle applications from to R12.1.3 in RHEL6.

      As part of upgrade, we applied

      1) Critical pre-upgrade patches for Financials in preinstall mode.

      This created preinstall directory under $APPL_TOP/admin/$TWO_TASK


      To merge the pre-install patches:

      • Review the contents of the $APPL_TOP/admin/$TWO_TASK/preinstall directory and ensure that only the patch drivers of the desired pre-install patches are present in the directory.
      • Merge the patch drivers present in the $APPL_TOP/admin/$TWO_TASK/preinstall directory with the Release 12.1 upgrade driver $AU_TOP/patch/115/driver/u6678700.drv.

        • Change directory to $AU_TOP/patch/115/driver. For example:

          cd $AU_TOP/patch/115/driver

        • Perform the merge using the following command:

          admrgpch -d . -preinstall -master u6678700.drv

          Note: By default, the merged driver is created in the specified destination directory with the name u_merged.drv.


      2) Now,

      Before applying 7303029:12.1.0 in "preinstall" mode -



      If you have applied any other patch previously in preinstall mode and do not

      intend to merge it with 12.1.1 upgrade driver u6678700.drv, clean-up the

      directory $APPL_TOP/admin/$TWO_TASK/preinstall after taking the backup of

      current directory.



      Can anyone clarify the above contradict statement?

      As per Pre-install Patches Report, we need to merge the preinstall directory along with main driver but as per patch 7303029, preinstall directory should be clean-up.

      Should we need to rename preinstall directory created by preinstall patches or not?


      Gone through below link.  But still expecting more clarity on this.

          Hi All,


          Raised an SR and got confirmation.


          We should not get confused on the Below statement.


          We should apply all Critical pre-upgrade patches for Financials in preinstall mode and 7303029:12.1.0 in "preinstall" mode and then merge those with main driver.

          Clean up of preinstall directory only requires when there is any other patch applied in preinstall mode( which is not part of upgrade ), only those needs to get cleaned up.
