Installing Cisco IOS for S/390 Release 2.0

Media media_name is now operational with one or more active interfaces.

Callable System Services Library

You must have the Callable System Services library, SYS1.CSSLIB, available for the installation. Modules from this library are linked with Cisco IOS for S/390 release 2.0 for OpenEdition support. This library is distributed with MVS/ESA. If you do not have this library available, OpenEdition support will not function properly.

TSO/E

New users must verify that the IBM program product TSO/E is installed. Cisco IOS for S/390 configuration files are parsed using TSO/E parsing routines and S0C4 ABENDs can result if these routines are not available.

ACF/2

For some users of CA-ACF2, the CA-ACF2 fixes listed here affect the way the Cisco IOS for S/390 SAF security interface to CA-ACF2 works. These fixes should be reviewed by the CA-ACF2 Systems Programmer to determine if they are still applicable or have been superseded by later maintenance.

SAS/C Release Level

Cisco IOS for S/390 release 2.0 is designed to work with SAS/C Release 6.00, which is included with the product. If you are not running with the correct SAS/C libraries, unpredictable results may occur.

The zap associated with Usage Note 1670 for SAS/C 6.0 must be applied in order to run applications via IUCV over the SAS LSCNCOM interface, including SAS/connect.

Asynchronous Sockets

Cisco IOS for S/390 release 2.0 supports asynchronous socket calls from OpenEdition. The following system levels are required to run this option:

OS/390 V1.3 requires PTF level 9705 or higher

DB2 V5 requires PTF level 9708 or higher
