Last updated on JULY 05, 2017

Applies to:

Oracle Data Provider for .NET - Version: 11.1.0.6.20 and later   [Release: and later ]
Oracle Provider for OLE DB - Version: 11.1.0.6.20 and later ]
Microsoft Windows (32-bit)

Symptoms

After applying RDBMS patchset 11.1.0.7 over an 11.1.0.6.20 ODAC install removes / deletes some folders from the ODAC Home (i.e. folders which are not on the exclude list in instclient.bat).

The major directories which disappears are :
jre
lib
Network
OPatch
oui
relnotes

Changes

The 11g ODAC does a non-standard Instant Client installation with subdirectories. Which when applying the 11.1.0.7 RDBMS patchsets, it is looking for the standard instant client installation.
