Explanation
 The requested VTAM® function
to allocate a conversation was not performed because the VTAM MODE specified a conversation limit of
zero. The conversation limits must be set to a value greater than
zero before a conversation can be allocated.

System action
 The conversation is not allocated.

Operator response
 Notify the system programmer.

System programmer response
 If you have placed entries in the
SYSIBM.LUMODES table, make sure CONVLIMIT column has a nonzero value.
If you are allowing the session limits to be chosen by VTAM, make sure the DSESLIM values on the VTAM APPL and mode entries are
nonzero.

Problem determination
 Collect the following diagnostic items:

Determine the LUNAME and MODE name of the Db2 system that attempted to start a VTAM conversation.

Print the contents of the SYSIBM.LUMODES table.

Determine the session limits defined on the VTAM APPL statement and the VTAM MODE entry.
