Short Description Tips and Tricks to Automation Engine Best Practices via ucsrv.ini Detailed Description and Symptoms If you are seeing a slow-down or performance issues of your User Interface or jobs running, this could be caused by many issues. Before contacting support, there are some important settings that should be set in the ucsrv.ini file as a best practice. Solution The two settings to look at are in the ucsrv.ini file as described below: *) PrimaryMode= The first is to change your ucsrv.ini file on all Automation Engine components, setting: PrimaryMode=1 This will cause the PWP to only focus on PWP tasks rather than work on regular WP tasks as well. If PrimaryMode is set to 0, the PWP will do regular WP work as well rather than it's specific tasks. At times, a regular WP may have a call to the database for many reasons that can take over 10 minutes. If this happens and the PWP is doing the work, no other work is done at the time and the entire system can go down. Setting PrimaryMode to 1 will greatly reduce the chance of this happening. More information on this setting can be found in the documentation under Administrator Manual, Configuration, Structure of the Configuration Files, UC4 Servers. *) srvquery= The second setting that is important to have set in the ucsrv.ini file on all Automation Engine components, setting: srvquery=1 This setting will cause the keepalive sent to the agent to be done by the CPs rather than the WPs, relieving some of the stress and constraints on the WPs. More information on this setting can be found in the documentation under Administrator Manual, Configuration, Structure of the Configuration Files, UC4 Servers.
