Prerequisite Check “CheckActiveFilesAndExecutables” Failed
While applying a patch to oracle binary using opatch utility, got below error.
Solution : While applying patch using opatch, all processes using that ORACLE_HOME should be done. If any of the processes are still using the ORACLE_HOME, It will fail with above error.
Now find the process id using below command.
/sbin/fuser /oracle/app/oracle/product/12.1.0/prim/lib/libclntsh.so.12.1 /oracle/app/oracle/product/12.1.0/prim/lib/libclntsh.so.12.1: 29274m 29786m ps -ef | grep 29786 ps -ef | grep 29274
Kill both the process:
kill -9 29786 29274 /sbin/fuser /oracle/app/oracle/product/12.1.0/prim/lib/libsqlplus.so /oracle/app/oracle/product/12.1.0/prim/lib/libsqlplus.so:
If this command shows any process id , then those need to be killed also.
Now retry the opatch :
# $ORACLE_HOME/OPatch/opatch apply
We have applied the patch successfully.
P.S. :
So before running the opatch apply command directly, it is better to run the below command, to check whether any process using the oracle binary or not.
[oracle@node1 27072683]$ $ORACLE_HOME/OPatch/opatch prereq CheckActiveFilesAndExecutables -ph ./
