OCSSD is the most critical process of clusterware. If CSSD is abnormal, the system restarts immediately. in the LINUX test environment of 10.2.0.5/11.2.0.4, use kill-9 <ocssd pid> to test and immediately restart the system. The effect is the same as that of init 6. * ** This vulnerability also found:/u01/app/oracle/product/crs/bin/ocssd. bin is an ORACLE user. When ORACLE users KILL the process, LINUX will be restarted ~~~
This is not a security vulnerability. Haha.
