Description

These counter commands set a new current value for the named counter. COUNTER operates on fullword signed counters and DCOUNTER on doublewordunsigned counters.

You can use the COMPAREMAX and COMPAREMIN options to set a new current value only if it falls within a specified range, or is above or below a specified value.

For information about specifying fullword and doubleword variables on these named counter commands, see CICS command argument values.

Options

COMPAREMAX(data-value)
specifies, as a fullword signed binary value (doubleword unsigned binary value for DCOUNTER), a value to be compared with the named counter's current value, and makes the result of the UPDATE command conditional on the comparison:
  • If the current value to be assigned is less than, or equal to, the value specified on the COMPAREMAX parameter, the current value is reset, with response normal
  • If the current value is greater than the specified value, CICS returns an exception condition.

The value you specify on the COMPAREMAX parameter can be less than the value on the COMPAREMIN parameter, in which case the current value is considered to be in range if it satsifies the COMPAREMIN or the COMPAREMAX comparison. In the normal case where the COMPAREMIN value is less than the COMPAREMAX value, the current value must satisfy both comparisons (that is, it must lie between the two values).

COMPAREMIN(data-value)
specifies, as a fullword signed binary value (doubleword unsigned binary value for DCOUNTER), a value to be compared with the named counter's current value, and makes the result of the UPDATE command conditional on the comparison:
  • If the current value to be assigned is equal to, or greater than, the value specified on the COMPAREMIN parameter, the CICS resets the current value, with response normal
  • If the current value is less than the specified value, CICS returns an exception condition.
Note: The value you specify on the COMPAREMIN parameter can be greater than the value on the COMPAREMAX parameter. See the COMPAREMAX parameter for the effect of this.
COUNTER(name)
specifies the name of the named counter for which the current number is to be reset to the value specified on the value parameter. The name can be up to 16 alphanumeric characters. If name is a variable that contains a name that is less than 16 characters, the name must be padded with trailing blanks.
DCOUNTER(name)
specifies the name of the named counter for which the current number is to be reset to the value specified on the value parameter. The name can be up to 16 alphanumeric characters. If name is a variable that contains a name that is less than 16 characters, the name must be padded with trailing blanks.
POOL(poolname)
specifies the name of the pool in which the named counter resides.

Valid characters for the pool selector string are A through Z, 0 through 9, $ @ # and _ (underscore). If name is a variable that contains a name that is less than 8 characters, the name must be padded with trailing blanks.

This parameter is optional. If you omit the name of the pool, a pool selector value of 8 blanks is assumed.

If there is no matching entry in the DFHNCOPT options table, CICS uses the name specified on the NCPLDFT system initialization parameter, which specifies the default named counter pool.

For information about generating a named counter options table using the DFHNCO macro, see the CICS Application Programming Guide.

VALUE(data-value)
specifies the new number to be set as the current value for the named counter, using a fullword signed binary value for COUNTER and a doubleword unsigned value for DCOUNTER.

Conditions

INVREQ
RESP2 values:
201
Named counter not found.
301
The server has reported an error code that is not understood by the named counter interface. Generally, this is not possible unless the interface load module, DFHNCIF, is at a lower maintenance or release level than the server itself.
303
An unexpected error, such as structure failure or loss of connectivity, has occurred on a macro used to access the coupling facility. Further information can be found in message DFHNC0441 in the CICS job log.
304
The pool selection parameter specified in the program cannot be resolved to a valid server name using the current options table.
305
The interface is unable to establish a connection to the server for the selected named counter pool. Further information can be found in an AXM services message (AXMSCnnnn) in the CICS job log.
306
An abend occurred during server processing of a request. Further information can be found in a message in the CICS job log and the server job log.
308
The DFHNCOPT options table module, required for resolving a pool name, could not be loaded.
309
During processing of the options table, the named counter interface encountered an unknown entry format. Either the options table is not correctly generated, or the DFHNCIF interface load module is not at the same release level as the options table.
310
An options table entry matching the given pool name specified a user exit program, but the user exit program is not link-edited with the options table and cannot be loaded.
311
A response from the named counter server to the client region interface module, DFHNCIF, indicates that a system-managed rebuild is in progress but the EXEC CICS interface does not recognize the condition. This means that the CICS region is at CICS TS 2.1 or earlier.
403
The POOL parameter contains invalid characters or embedded spaces.
404
The COUNTER parameter contains invalid characters or embedded spaces.
406
The VALUE parameter is invalid. You cannot set the current value to less than the minimum value, or greater than the maximum value plus 1.

Default action: terminate the task abnormally.

SUPPRESSED
RESP2 values:
103
The current value of the named counter is:
  • not within the range specified by the COMPAREMAX and COMPAREMIN parameters, when both are specified
  • greater than the COMPAREMAX parameter or less than the COMPAREMIN parameter, when only one option is specified.

Default action: terminate the task abnormally.
