LMUPDEF

LMUPDEF Command and Control Statement

The LMUPDEF command and control statement is used to specify the definition data set that contains network LMU attachment (LMUPATH) statements. The data set must be a sequential or a partitioned data set (PDS) with any valid record format (RECFM). Also, the data set must contain one or more LMUPATH statements.

The LMUPDEF statement can be specified in PARMLIB, or it can be issued as an operator command to dynamically load or reload LMUPATH parameters. (Refer to ‘‘PARMLIB Control Statements’’ in the HSC Installation Guide for an explanation of PARMLIB.)

If a definition file is changed by a LMUPDEF operator command, and if the change is to be permanent, you must update PARMLIB before restarting the HSC. If the definition file is to be modified for a given shift or application, remember that the new definition remains in effect until another definition is loaded or the HSC is recycled. The definition file then reverts to the PARMLIB specification. Thus, LMUPDEF can be used to temporarily change a definition file.

Definition commands issued on one host are in effect only on that host. If different hosts use the same definition data set, the LMUPATH parameter statements are shared by those hosts.

Notes:

1.Users can find additional important TCP/IP-related information by referring to “Dynamic LMU Connection” on page 70. To display the LMUPDEF data set, refer to Display LMUPDEF in the HSC Operator’s Guide.

2.When the LMUPDEF command is issued, if the definition data set contains errors, an HSC message provides the parameter in error, a description of the problem, and the line number where the error occurred. If the definition data set contains errors, none of the attributes specified in the LMUPATH control statement(s) will be loaded (put into effect). Message SLS1627I is displayed if errors are encountered. If 50 errors are encountered, the remainder of the data set is not checked. Correct the problem and reissue the command.

3.The LMUPDEF command and control statement executes at both base and full service levels of the HSC.

4.If you issue multiple LMUPDEF commands or statements, the last one processed is currently active. You can determine which LMUPDEF statement is active by entering the Display LMUPDEF command.

5.In order for the new IP addresses to take effect, users must first establish IP addresses with the LMUPDEF command. Next, vary the ACS(s) offline and then online, using the Vary ACS operator command.
