While patching oracle 19c database JAVA component , the following errors were thrown:

Patching component oracle.javavm.client, 19.0.0.0.0…
Make failed to invoke “/usr/bin/make -f ins_rdbms.mk javavm_refresh ORACLE_HOME=/opt/oracle/product/19c/dbhome_1 OPATCH_SESSION=apply”….’make: perl: Command not found
make: *** [javavm_refresh] Error 127

NApply was not able to restore the home. Please invoke the following scripts:

• restore.[sh,bat]
• make.txt (Unix only)
  to restore the ORACLE_HOME. They are located under
  “/opt/oracle/product/19c/dbhome_1/.patch_storage/NApply/2023-11-01_14-06-22PM”

UtilSession failed: Re-link fails on target “javavm_refresh”.

OPatch failed with error code 73

Solution:

The first thing I will do is to restore the oracle database binaries to a consistent state:

cd /opt/oracle/product/19c/dbhome_1/.patch_storage/NApply/2023-11-01_14-06-22PM

./restore.sh

The second step is to add perl location in your $PATH environment variable $ORACLE_HOME/perl/bin and test it after profile reload:

echo $PATH

env | grep perl

After that using OPatch utility try to apply java patch again….should be successful !
