Hi Nidhi,
SQL30082N RC=19 means:
19
USERID DISABLED or RESTRICTED
The userid has been disabled, or the userid has been restricted from accessing the operating environment at this time.
Suggested remedy is :-) :
19
Ensure that the proper userid and/or password is supplied to access the IBM Cloud DB2.
The userid may be disabled, the userid may be restricted to accessing specific IBM Cloud DB2, or the userid may be restricted to certain hours of operation.
Please let me know if this helps you.
