Error description
The Log Reader Server is exploited by the Db2 HPU unload steps that specify the AT QUIESCE option only if the VUU11/RDLOGMOD parmlib parameter select the server mode. Therefore, to avoid the useless run of the related permanent job, any attempt to start the Log Reader server with the START LOG SERVER command should not be honored if the VUU11/RDLOGMOD parmlib parameter is set to STANDALONE.
