DB2 SQL Error: SQLCODE=-805, SQLSTATE=51002, SQLERRMC=NULLID.SYSLH203

I encountered this exception when running a custom batch job in WCS which used JDBCHelper to update data into WCS Tables.

The reason for this is that the JDBCConnection was not closed.
It looks like we need to close and open the connection frequently, else it results in too many open statements and results in this error.
