On a grid infra-structure (18.104.22.168.0) cluster (SRVR1Rr – 2r -3r) we got more and more tickets that the ASM instances where having fragmented memory for the shared pool. The investigation showed that there was no SPFILE present, with automatic memory management in there. So this environment clearly needed better. Only thing found was some out of date INIT.ORA. From history this environment had been set up as an 11gr1 RAC cluster, and some time ago it had been upgraded to 11gr2 Grid Infra.
