Hi,
This can happen if the machine is overloaded.
The below reason can fix your issue.
- Bad kernel parameters settings (e.g. "ulimit" set too small)
- Incorrect permissions on the ORACLE executable ($ORACLE_HOME/bin/oracle.exe)
- $ORACLE_HOME/rdbms/lib/config.o is 0 bytes
- Oracle binaries have not been linked correctly
if everthing looks fine then login will ORS_SID and execute the below command as per your issue.
$ relink all:
I hope your issue will resolved.
Thanks,
BM
