Use this command to initialize the node control block (NCB) records in the
TPF system.
Requirements and Restrictions
- You can enter this command only in 1052 state or higher.
- You cannot initialize the NCB records when the NCB reconciliation function
or the NCB reorganization function is running.
- Note:
- You can enter the ZNNCB RECON command to end the NCB reconciliation function
or the ZNNCB REORG command to end the NCB reorganization function.
- NCB records are initialized only if there are no active sessions for the
logical unit (LU) resource.
Format
- ALL
- initializes all of the NCB records in the TPF system.
- MOD module
- initializes all of the NCB records on a module, where module is
the hexadecimal module number.
- NAME or NOD
- initializes the NCB for a specific LU resource.
- netid.name
- 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
- Online help information is available for this command. To display
the help information, enter one of the following:
ZNNCB HELP
ZNNCB ?
- This command initializes both the fixed file and long-term pool file NCB
records. LU resources created using the offline ACF/SNA table
generation (OSTG) program use fixed file NCB records. All of the other
LU resources use long-term pool file NCB records.
Examples
All of the NCB records in the TPF system are initialized in the following
example.
