Tomcat Performance issue in SAP Business Objects 4.1 SP7

A New Installation of SAP Business Objects 4.1 SP7 with default Tomcat 7.0 Installation comes with (-Xmx) = 2048M & MaxPermSize = 384M.

However in some cases when there are multiple users login & execution of reports are happening then this memory is quite low & you can see the performance issue in your BO server where Adaptive Processing Server started responding very slow & sometime it’s hang while creating OLAP connections.

Some errors can be visible in logging directory of Tomcat on below file –

/usr/sap//bin
However in the BO system setenv.sh defined parameter to use bobjenv.sh file for memory related parameters.

We can increase the Tomcat memory on below file as per SAP recommendation –

/usr/sap/SID/sap_bobj/tomcat/bin/bobjenv.sh

Create a backup of original file & change the parameter of above file as per below notes.

Please Note – Before updating any Tomcat memory parameter, shut down the BO application & Tomcat, update the parameter & Restart the Tomcat & BO applications.

Verify the Memory of Tomcat in Linux –

ps -ef | grep tomcat ——— see the new memory parameter.
