Configuring Application Server
Use the same steps in Configuring Application Server with the following notes:
• QADCRMInstallDir refers to the newly installed CRM 6.6.1 folders on your Windows Deployment server.
• Back up your existing ubroker.propoerties file before you make any changes to it.
• It is recommended that you define a new entry in the ubroker.properties file rather than updating the existing CRM6.5.1 entry. You can always remove the existing CRM6.5.1 AppServer later after your CRM 6.6.1 system is confirmed to be working.
• When defining the PROPATH for your AppServer, make sure that you refer to the correct QADERPInstallDir/qadcrm/<New CRM6.6.1 env name> folder that you created in an earlier upgrade step in Copying QAD Backend Programs on the Application Server.
