Today I’ve came across strange error related to srvctl add service.
$ srvctl add service -d db -s SERVICE_NAME -preferred INST1,INST2
PRCR-1006 : Failed to add resource ora.db.db_service.svc for SERVICE_NAME
PRCT-1011 : Failed to run "osdbagrp". Detailed error:
Hey. Hypothetical situation. You have freshly installed OS Linux, and you wanna install Oracle GRID+RDBMS there. But you have another server with has already installed Oracle. All you need it’s just copy Oracle homes, and do couple steps.
Today I’ve stumbled upon on ORA-15196: invalid ASM block header during making backup through RMAN.
The new paradigm of manipulate cluster resources in 12c little bit annoying me.
crsctl start resource ora.DATA.ACFS.advm
CRS-4995: The command 'start resource' is invalid in crsctl. Use srvctl for this command.
You might wonder how CSSD, which is required to start the clustered ASM instance, can be started if voting disks are stored in ASM? This sound like a chicken-and-egg problem. Without access to the voting disks there is no CSS, hence the node can’t join the cluster. But without begin part of the cluster, CSSD can’t start the ASM instance. To solve this problem the ASM disk headers have metadata since 11.2. You can use kfed to read the headers of ASM disks containing a voting disk. The kfdhdb.vfstart and kfdhdb.vfend fields tell CSS where to find the voting file. This does not require the ASM instance to be up. Once the voting disks are located, CSS can access them and joins the cluster.

ONE MORE THING
If you’ve got more than one node, and in some reason you have different patch levels between nodes.
For example after unseccessful patching action. You need to use clscfg -localpatch for patching OLR, and ater that clscfg -patch for patching OCR.
Some day ago I’m stumbled upon problem while has upgraded 12c cluster. In our lab we have next plan for upgrade.
1. Install new GI soft without configuring.
2. Configure new GI.
So, after executed config.sh we need to execute rootupgrade.sh and here we stumbled upon problem.
