Datapump bundle patches are special patches for datapump component of the Oracle database system, and can be applied “AFTER” the main database patch is applied…The RU (release update) patch needs to be already applied on the Oracle DB System.

its important to mention that this patch is considered “Non-Binary Online Patch” which means you can apply it while database is up and running fine. However, you need to make sure no datapump jobs are currently running while applying the patch.

The benefits of applying this patch are many…for example bug fixes for datapump component will be fixed, it will speed up datapump operations…etc.

First, check there are No pre-requisite conflicts:

$ORACLE_HOME/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -ph ./

Then, go to the directory where the datapump patch is located:

cd /var/DATAPUMP_BUNDLE_PATCH_19.19.0.0.0/35261302

After that, apply the patch through OPATCH utility (use latest one)
