Control File Manager function

Purpose

To provide support to display and set performance parameters for the Control File Manager.

Function identifier

CFM

Description of usage

The CFM SET command allows you to set the same performance parameters that are supported on the FILE CF initialization statement. You can display these parameters with the CFM DISPLAY command.

To display the current settings for the control file

/CFM DISPLAY

The output has the following format:

DTM6108I CONTROL FILE OPTIONS:
  DSN=TM.CONTROL.FILE ON SYSV03
      MINDORM MAXDORM MINHOLD
          1     6000       50

If a MAXHOLD value has been set, it is displayed instead of MINHOLD.

To change settings for the control file

/CFM SET MINDORM(nnnn) MAXDORM(nnnnn) MINHOLD(nnnnn)

The recommended setting for each of these values is double the JES2 setting used by your installation. MAXHOLD can be specified instead of MINHOLD. Note that they are mutually exclusive.

The CFM DELETE NODE command allows you to remove from the Control File information about JES2 nodes that no longer share the file.

To remove a JES2 node from the control file

/CFM DELETE NODE 3

Note that node number required for this command is not the JES2 node number. To get the Control File node number required for the CFM DELETE NODE command, use the NODES keyword for the CFM DISPLAY command:

/CFM DISPLAY NODES

The resulting display shows the Control File node number in the first column, headed NN in the following sample output:

DTM6113I CONTROL FILE NODE DISPLAY
NN NAME ACTIVE SPOOL DSNAME AND VOLUME PREFIX
== ====     ====== ==============================
03 BRANCH3 NO     JES2.SPOOL.DSNAME,VOLSE
01 BRANCH1 NO     SYS1.HASPACE,SPOOL
-- HQ       YES    SYS1.HASPACE,SPOOL

To change the way WLM accounts for jobs held by JBS and JLS

When jobs are held by JBS or JLS, WLM normally accounts for the delay in the "operator hold" category. You can change this behavior with the CFM SET RESOURCEHOLD command:

/CFM SET RESOURCEHOLD(ON)

When RESOURCEHOLD is set to ON, the delay is accumulated in the "lack of resource" category instead.
