opatch prereq CheckConflict fails with Exception occured : PatchObject constructor:Input file does not exist (Doc ID 788181.1)

Last updated on SEPTEMBER 20, 2018

Applies to:

Oracle Database - Enterprise Edition - Version to [Release 12.1]
Oracle Universal Installer - Version and later
Information in this document applies to any platform.


Following error is reported while checking for conflict among patches which are to be applied (where one of the patches is a napply patch)

For example, which checking for conflict between two patches Patch 608154 and Patch 5892355

Patch 6081547 and Patch 5892355 are taken here as an example only, to explain the issue and they should not be applied to the Oracle Home unless it was advised by Oracle.

Would like to know whether there is any potential conflict between patches before they are applied.

For example, while checking for conflict between two patches 6081547 (napply patch) and 5892355

When Patch 6081547 was unzipped, four other patch directories are created and 6081547 is not present, even though the fix for concerned bug is included in the napply patch.

$ cd $ORACLE_HOME/patches/6081547
