Cisco IOS for S/390 System Management Guide

Customizing CA-ACF2 Version 6 or Later

A correction is required for Chapter 3 of the Cisco IOS for S/290 Planning Guide. Under the heading Customizing CA-ACF2 Version 6 or Later (page 3-12), step 2 is Update GSO Records for Cisco IOS for S/390. The code listed in this step is incorrect. The correct code is:

ACF

SET CONTROL(GSO)

INSERT CLASMAP.AC#CMD RESOURCE(AC#CMD) RSRCTYPE(SAF) ENTITYLN(8)

CHANGE INFODIR TYPES(D-RSAF)

INSERT SAFDEF.ACSECPC1 ID(ACSECPC) MODE(GLOBAL) REP

INSERT SAFDEF.ACSECPC2 ID(ACSECPC) MODE(GLOBAL) REP

PROGRAM(BYPASS#2) RACROUTE(SUBSYS=SNSTCP,REQSTOR=ACSECPC)

INSERT SAFDEF.ACSECPC3 ID(ACSECPC) MODE(GLOBAL) REP

Cisco IOS for S/390 System Management Guide

The information in this section should be added to the Cisco IOS for S/390 System Management

Guide.

Refreshing USSTAB

USSTAB tables can be refreshed with the REFRESH command.

In the “APP Commands” section, which describes the REFRESH command, the second sentence of the description of the REFRESH command, the USS Table should be added. That sentence should be corrected to read as follows:

“It can be used to refresh the LU pool, greeting member, or the USS Table used by Server Telnet.”

The correct syntax is:

[ APP ] REFRESH TASK ( n ) [ LUPARM ( mem_name ) GREETING ( mem_name )

USSTAB ( tbl_name ) ]

Syntax Description

 

USSTAB (tbl_name)

Specifies the USS Table tbl_name coded in the active APPCFGxx SERVICE

 

segment to be refreshed.

Note LUPARM, GREETING, and USSTAB are mutually exclusive.

The following is an example of the usage of the REFRESH USSTAB command.

REFRESH USSTAB( T01USS01 ) TASK( 1 )
