Hello Mahipal,
you have to upgrade to MaxBD 7.5 at least.
You can find the software here:
http://service.sap.com/swdc -> Database and Database Patches (from other vendors) -> SAP MaxDB -> Database -> MAXDB
It should be on the Installation DVD.
You should find the guide here:

Best regards
Christian
