DSNT379I CANNOT IDENTIFY TO IRLM. INVALID SSNAME OR IRLM IS NOT CURRENTLY ACTIVE

Explanation
 Either an attempt was made to identify the IRLM
with a subsystem name not recognized by MVS™,
or the IRLM is not currently active. This message is also issued
if common service area (CSA) storage is insufficient.

System action
 DB2® abends
with a reason code of X'04E'.

Operator response
 Notify system programmer.

System programmer response
 This is probably a user error. Change
the IRLMSID parameter in the DB2 DSN6SPRM
initialization macro to match the MVS subsystem
table, or start IRLM if IRLM is not already up. See return code
00E30079 for further information about determining the cause of the
error.
