Explanation
XCF could not successfully process a SETXCF,MODIFY
CLASSDEF command to change a transport class definition.
In
the message text:
- classname
- The name of the transport class.
- minimum
- The minimum usable value for MAXMSG.
- NOT DEFINED
- The transport class, classname, is not defined
to XCF.
- MAXMSG MUST BE AT LEAST minimum
- The MAXMSG value defined for transport class classname is
not large enough. MAXMSG must provide enough message buffer space
for at least one message as long as the class length. For this transport
class, the MAXMSG value must be greater than or equal to minimum.
The
system issues this text only if one or both of
the MAXMSG and CLASSLEN keywords was specified on the command. If
one of the keywords was not specified, the value used to test the
condition was the current value for the transport class.
- OUTBOUND PATHS MUST HAVE MAXMSG OF AT LEAST minimum
- The command specified a larger CLASSLEN value for the transport
class, but there are one or more outbound signalling paths with a
MAXMSG value too small for the larger class length. Each outbound
signalling path assigned to this class must have a MAXMSG value equal
to or greater than minimum. Note that using the minimum value
for MAXMSG may not provide sufficient buffer space for good signalling
performance.
System action
The system ignores the SETXCF MODIFY,CLASSDEF
command.
Operator response
Depending on the message text, do one of the
following:
- NOT DEFINED
- Enter the DISPLAY XCF,CLASSDEF command to list the names of the
transport classes currently defined. Reenter the command with the
correct class name.
- MAXMSG MUST BE AT LEAST minimum
- Enter the DISPLAY XCF,CLASSDEF,CLASS=(classname)
command to display the values of the unspecified parameters for the
transport class.
To change the transport class definition to the
desired class length, the MAXMSG value must be equal to or greater
than minimum.
- OUTBOUND PATHS MUST HAVE MAXMSG OF AT LEAST minimum
- Enter the DISPLAY XCF,PATHOUT,CLASS=(classname)
command to list the MAXMSG values for all the outbound signalling
paths assigned to this class. Each signalling path listed must have
a MAXMSG value greater than or equal to minimum before
the CLASSLEN can be set to the requested value. Use the SETXCF MODIFY,PATHOUT
command to change the MAXMSG values for any signalling paths that
are not equal to or greater than minimum.
