Explanation
The MAXMSG value, in kilobytes, of message buffer
space, defined on a COUPLExx parmlib member statement is too small.
The MAXMSG value must provide enough buffer space for a message as
long as the class length defined for the indicated transport class.
In
the message text:
- statement
- The statement can be one of the following:
- CLASSDEF
- The MAXMSG value for a CLASSDEF statement is incorrect.
- LOCALMSG
- The MAXMSG value for a LOCALMSG statement is incorrect.
- PATHOUT dev
- The MAXMSG value for a PATHOUT statement is incorrect. dev is
the device number of the outbound signalling path.
- COUPLE
- The MAXMSG value for the COUPLE statement is incorrect.
- minimum
- The least possible value for MAXMSG, in kilobytes, to support
the class length of this transport class. Note that setting the MAXMSG
value to minimum may not provide sufficient buffer space to ensure
good signalling performance.
- classlen
- The length, in bytes, of messages allowed for this this transport
class.
- classname
- The name of this transport class.
System action
The system prompts the operator for a new COUPLExx
parmlib member and waits for the operator to reply.
Operator response
Record the indicated statement, classname,
and classlen. Notify the system programmer of the
problem.
Specify a new COUPLExx parmlib member when prompted.
System programmer response
In the COUPLExx parmlib member, increase
the MAXMSG value or decrease the CLASSLEN value of transport class classname.
