Connecting to Mainframes DB using a .NET interface

[Neharao1]

Hi

I have developed a tool using .NET framework to connect to a database which is on Z/oS ( Mainframes System). And i was able to query the data of the tables existing in Z/oS DB using my tool.

But when i connected to one specific Z/oS systems i get an error saying "[DB2] SQL0551N "R06374" does not have the privilege to perform operation "EXECUTE PACKAGE" on object "NULLID.SYSSH200". SQLSTATE=42501" for a simple SELECT query. where as this error doesnt occur when i connect to other mainframes system.

Can someone advice me what is wrong. Why does that error occur only when i connect to one specific Z/oS system why not for others though the ID has dbadmin privileges

Thanks
