Before starting Oracle GoldenGate, specify the name of the Oracle GoldenGate for DB2 for i library when running the ggos400install script. This creates a link to the OGGPRCJRN *SRVPGM (service program) object that was restored to that library. If the link to the oggprcjrn service program is deleted you could just re-run the ggos400install shell script and specify the same library, or use the command "ln -s /qsys.lib/OGG_library.lib/oggprcjrn.srvpgm oggprcjrn.srvpgm". If this link is incorrect or missing, Extract will abend.
