Do you know what mean the parameters on installing 12c?
This parameter controls the kernel’s behaviour when an oops or bug is encountered:
- 0: try to continue operation
- 1: panic immediately. If the `panic’ sysctl is also non-zero then the machine will be rebooted.
OOPS is a deviation from correct behavior of the Linux kernel, one that produces a certain error log.
The better-known kernel panic condition results from many kinds of oops, but other instances of an oops event may allow continued operation with compromised reliability.
This is recommended in a system where we want to have node evicted in case of any hardware failure or any other issue.
To adjust as recommended by Oracle?
1. Put an entry in sysctl.conf for having it permanent:
kernel.panic_on_oops = 1
2. Refresh running command:
