Purpose

This note will provide what needs to check when dbca doesn't show ASM diskgroup information when creating a database using dbca in 11gR2 single instance environment.


From 11gR2 onward, dbca checks ASM instance liveness by looking at the status of ora.asm resource. If ora.asm is in "OFFLINE" or "UNKNOWN" for any reason or has not been added as resource for HAS ( High-Availability Service), dbca doesn't show ASM diskgroup information even though ASM instance is up and running.


Symptoms

1. After ASM is selected for database files, ASM diskgroup is not shown in dbca screen.

2. v$asm_diskgroup shows a proper informtion using sqlplus after connecting to ASM instance.

3. The following message is seen in dbca trace file located in $ORACLE_BASE/cfgtoollogs/dbca/trace.log_Ora<Home_Name>  

3-1. ASM resource ( ora.asm ) has been added to HAS resource but the status is "OFFLINE" or "UNKNOWN".
