OR Question 2
If the above scenario isnt possible, and I performed an uninstall, and after installing all the usage types again, and recovering the database....will i be able to get my integrated BI/ERP client back with it .. or will i have to perform the setup of BI client again ?
Thanks for your valuable replies.
Regards,

Answer 1

First of all... As per SAP Installation guide additional usage type BI installation is POSSIBLE. 
Please check SAP Note [883948|https://websmp130.sap-ag.de/sap(bD1lbiZjPTAwMQ==)/bc/bsp/spn/sapnotes/index2.htm?numm=883948]
And I guess you have all the primary required components.i.e. ABAP,Java, EP, EPC ...

Above error is basically because of JDK and not because of BI
Please check following blogs...

As per this... following could be reason.
1. check that iaik_jce_export.jar file is NOT included into the CLASSPATH.
2.Use only one JDK version (or remove the other installed versions from the used environment variables).
3. SAP Note [739043|https://websmp130.sap-ag.de/sap(bD1lbiZjPTAwMQ==)/bc/bsp/spn/sapnotes/index2.htm?numm=739043]

I guess It might be difficult to UNINSTALL - may cause some inconsistencies in the current system.
Still - If you really Don't want BI now... Best option could be full restore and recovery.- If you have consistent backup.
But if you want BI - then, since above problem is because of JDK , I think it could be resolved.
Let us know if anything....
