Explanation
A SETXCF START,CLASSDEF command to start a transport
class was unsuccessful.
In the message text:
- classname
- The name of the transport class.
- minimum
- The minimum usable value for MAXMSG.
- DEFINITION ALREADY EXISTS
- The transport class classname is already defined.
- MAXIMUM NUMBER OF DEFINITIONS (62) EXIST
- This command request would bring the total number of transport
classes past the allowable maximum of 62 non-default class definitions.
- INSUFFICIENT SPACE
- XCF could not get the storage needed to create the transport class
definition requested in the command.
- MAXIMUM NUMBER OF GROUPS (2045) ASSIGNED
- The command requested that one or more groups be assigned to transport
class classname but this would bring the total
number of groups past the allowable maximum of 2045.
- MAXMSG MUST BE AT LEAST minimum
- The MAXMSG value defined for transport class classname is
not large enough. MAXMSG must be large enough to provide for at least
one message as large as the class length. For this transport class,
the MAXMSG value must be greater than or equal to minimum.
System action
SETXCF command processing ends.
Operator response
Depending on the message text, do one of the
following:
- DEFINITION ALREADY EXISTS
- Enter DISPLAY XCF,CLASSDEF to list the transport classes currently
defined to the system. Make sure the correct class name was entered.
If so, enter SETXCF MODIFY,CLASSDEF to change the definition.
- MAXIMUM NUMBER OF DEFINITIONS (62) EXIST
- Enter the SETXCF STOP,CLASSDEF command to delete an existing definition
if necessary.
- MAXMSG MUST BE AT LEAST minimum
- If MAXMSG or CLASSLEN was not specified, the values used were
the current default MAXMSG and CLASSLEN values. Enter the DISPLAY
XCF,COUPLE command to list the current default values for these parameters.
- INSUFFICIENT SPACE
- Do one of the following:
- Reenter the command. The storage constraint will probably resolve
itself.
- Enter the SETXCF MODIFY,CLASSDEF command with the DELGROUP keyword
to delete an explicitly assigned group from each transport class.
This may alleviate the storage problem.
- MAXIMUM NUMBER OF GROUPS (2045) ASSIGNED
- Enter the SETXCF MODIFY,CLASSDEF command with the DELGROUP keyword
to delete an explicitly assigned group from each transport class to
which it is assigned to reduce the total number of explicitly assigned
groups. Then try reissuing the SETXCF START,CLASSDEF command.
