ZNNCB RECON-Reconcile NCB Directory Records

Use this command to reconcile the node control block (NCB) directory records in the TPF system when they are becoming full. This function can delay the need for increasing the number of NCB directory records if the largest number of entries in an NCB directory record is reduced to an acceptable number.

Reconciling the NCB directory records does the following:

You can reconcile all of the NCB directory records or only the NCB directory record entry for a specific LU.

The following information is displayed when the NCB reconciliation function has been completed:

Requirements and Restrictions

Format




ABORT
cancels the NCB reconciliation function.
Note:
You can specify this parameter only when you enter the ZNNCB RECON command from the processor where the NCB reconciliation function was started. Specify the BP parameter to cancel the NCB reconciliation function from a processor other than the one where it was started.

BP
allows you to cancel the NCB reconciliation function from a processor other than the one where it was started.

ALL
reconciles all of the NCB directory records in the TPF system.

NAME or NOD
reconciles the entry in the NCB directory record for the specified LU resource.

netid.luname
is the 1- to 17-character network qualified name of an LU resource.  The network ID and name of a resource must both begin with a letter (A-Z), @, #, or $. The remaining characters can be letters (A-Z), numbers (0-9), @, #, or $. 
Note:
 To specify an SNA network ID or resource name that contains dollar signs ($), you must type two consecutive dollar signs ($$) for each dollar sign in the network ID or resource name. For example, if the SNA resource name is $SNANAME, you must type $$SNANAME

Additional Information

Examples

All of the NCB directory records in the TPF system are reconciled in following example. Notice that after the NCB reconciliation function has been completed, the NCB directory records are still rather full. This indicates that you should increase the number of NCB directory records by using the NCB reorganization function.

In the following example, the ZNNCB RECON command was entered to cancel the NCB reconciliation function from a processor other than the one where it was started. Notice that, in this example, you must specify the BP parameter.
