Hello, I am trying to apply the Patch 12311357 on my standalone grid infrastructure and single instance. But the thing is when trying to apply the PSU, it says: Cann't open /a01/app/oracle/product/11.2. 0/db_1/css/admin/init.cssd at /a01/app/oracle/product/11.2.0/db_1/OPatch/crs/auto_patch.pl line 3161. It seems like the PSU considers that is a cluster database. In all the readme document it doesn't mention single instance database. 3 weeks ago, I succesfully applied it in RAC 4 nodes, without issues. I wonder if someone tried it on a single instance? tahnk you
