I installed GI 188.8.131.52. In order not run setup with unpatched GI, I used "software only" installation. Then I installed GI PSU with "OPatch auto". PSU was installed with messages indicating failing of stop|start clusterware (file 'crsctl' was not found). Is it normal behaviour ?Yes. Oracle uses different versions of binaries for standalone server and for cluster. crsctl is missing until you configure GI.
Then I used asmca, but it failed because GI was not configured. In GI documentation written how to configure GI for cluster (crs/config/config.sh), but no info for standalone server. Should I reinstall GI using "standalone server" installation and only after this install PSU ?You can configure GI with following command as root :
$GRID_HOME/perl/bin/perl -I$GRID_HOME/perl/lib -I$GRID_HOME/crs/install $GRID_HOME/crs/install/roothas.pl
