Simplifying Migration Process – Changing Environment Specific Variables in RPD
When it comes to migrating repository file between environments (Dev – TEST-Prod), one of the common questions from OBIEE environment administrators is if there is a way to change the connection information without having to change them manually in all the places.
Creating repository variables for DSN and DSN Username solves the issue to an extent. However, imagine having to deal with changing multiple DSNs and their respective usernames. Moreover, there is the setting password to the DSN username. One way to automate the setting of the variables is to store the values in a file and set them via admin tool command line mode.
First, define repository variables that can be used in the connection pool.
Reference the DSN information in the connection pool.
Now create a control file SetVariables.txt with the environment specific values.
_______________
‘To Open rpd – Open <rpdname> <Administrator User> <administrator password>
Open YourRpd.rpd Administrator SADMIN
‘Setting OLAP DSN variable
SetProperty “Variable” “OLAP_DSN” Initializer ” ‘QA_DSN’ ”
‘ Setting OLAP DSN Username variable
SetProperty “Variable” “OLAP_DSN_USER” Initializer ” ‘QA_User’ ”
‘Setting OLAP DSN User QA database password
SetProperty “Connection Pool” “AppDW”.”Connection Pool” “Password” “QAPassword”
Save
Close
Exit
______________
Create one per environment.
In the command line run the following command:
AdminTool.exe /command SetVariables_QA.txt
And the repository is now prepped for the other environment (QA in this case).

Dinesh, the Admin tool cannot be opened on Unix. You need to do this in Windows.

Kumar,I followed the steps you mentioned but it is not changing the variable value.It is opening the rpd and closing but variables are not getting changed.Please help.

Yes it should open, change, and close. All these actions happen very quickly. Make sure that the variable names, etc in the file match the names in the rpd
