It seems New-SPPerformancePointServiceApplication cmdlet does not have -databaseName parameter as other cmdlets to create a service apps. I wonder if it is possible to create PerformancePoint services with custom database name via PowerShell?
If you run this command with the required parameters:
New-SPPerformancePointServiceApplication -Name "PerformancePointServices" -ApplicationPool "ServiceAppPool"
New Performance Point service app will be created and it's database name will be PerformancePointServices_GUID. I would like to be able to create a database with a custom name (without guid :))
