With this setup we are facing the issue that if we loose a complete SAN, the IO’s to the ASM diskgroups will be blocked for approx 3 till 4 minutes. Oracle does not like this. After 70 seconds after a freeze, rdbms is starting to reboot (expected behaviour).
Using rdbms 11.2 as the repository for our Grid Control environmont, noticed a lot of the same errors in the alert file of the repository or/and the target database:
NI cryptographic checksum mismatch error: 12599.
TNS for Linux: Version 188.8.131.52.0 – Production
Oracle Bequeath NT Protocol Adapter for Linux: Version 184.108.40.206.0 – Production
