I was looking to one of the PDN article and the prerequiste for keyring encryption is have the below jar file in the lib directory. I don't see these jars included as part of the BIX distribution directory. Please advise
If your prconfig.xml file includes both a PegaRULES and PegaDATA datasource then yes you will be prompted for username/password of each. If you also included a datasource for a target database then it should prompt you for that database username/password as well.
If you have both of those lines then you will need database entries for each and yes you will be prompted for both.
Not sure if this is true in earlier BIX 7.x versions but in 7.2 you can actually just keep this line and comment out the PegaDATA one since you really only are connecting using the PegaRULES datasource.
