MEMORY LEAK FIX FOR ONLINE PATCHING / HOT PATCHING
This reduces memory usage associated with the online patching feature.
?AIX 6.1 TL7 or above (such as AIX 7.1) must be installed before either installing the patch or relinking the Oracle binary for it to be effective.  If you are on an earlier version of AIX, then you may wish to consider installingPatch:10190759instead, but keep in mind that doing so will disable online patching.
