Hello, On one of our servers we are trying to upgrade to patch set 10.2.0.4. When installing the patch set 10.2.0.4 the following message is displayed. OUI-10091: There are no patches that need to be applied I checked the database version by querying v$version. This shows Code (Text): Oracle Database 10g Enterprise Edition Release 10.2.0.3.0 - 64bi PL/SQL Release 10.2.0.3.0 - Production CORE 10.2.0.3.0 Production TNS for Solaris: Version 10.2.0.3.0 - Production NLSRTL Version 10.2.0.3.0 - Production The inventory log shows the following: So apparently the Patchset has not been applied but it still keeps showing that there are no patches that need to be applied. So any suggestions of where to look for?
