I was getting error “shmget: [EEXIST][17]: key 52b14804: shared memory already exists” in online log and I notice OS physical memory and kernel parameters (shmmax) have much more available memory. But Informix instance unable to allocate new shared memory virtual segment during run-time from OS kernel. I notice there is no AF file (Assert Failed) generated.
I have raised a case to IBM Informix and confirm it was encountering IDS bug with product defect number idsdb00206627.

PRCR-1079 : Failed to start resource ora.mydb.db
CRS-2640: Required resource ‘ora.ARC2_DG.dg’ is missing.
How to remove the ASM resource from CRS start/stop dependency?
Applies to:
Oracle 11gR2 RAC
Scenario:
(2 node RAC with 11gR2 in RHEL 5.3 x86_64)
I was having 2 ASM diskgroup (ARC1_DG & ARC2_DG) assigned for archive logs and standby Dataguard when first RAC .
Due to some reason that management want to merge these 2 diskgroups into one (ARC1_DG).
I confimed that ARC2_DG was not contain any file and diskgroup ARC2_DG dropped successfully.
