Migrating to Version 7.1

This information details any special action you need to take if migrating from an earlier version of the product.

Installation location

If you are upgrading from Version 5, Version 6 or Version 7, the product is installed into your existing directory structure, replacing the older version.

Removal of TCP62 support

The announcement of CICS Transaction Gateway for z/OS V6.1 indicated that the releases of CICS Transaction Gateway V7.0 and CICS Universal Client V7.0, would be the last releases that would contain TCP62 support for the AnyNet protocol communicating with remote CICS systems using SNA over TCP/IP protocol encapsulation. Accordingly, this capability has been removed from the V7.1 level of the products. For continued use of SNA over TCP/IP, it is necessary to migrate TCP62 server definitions to SNA and implement another IBM Communications Server TCP/IP protocol encapsulation solution, such as Enterprise Extender or Remote API client support.

For information on migrating from TCP62 to Enterprise Extender support refer to the IBM publication Migrating an SNA connection from TCP62 to Enterprise Extender - GC34-6889-00.

For information on the removal of AnyNet support from z/OS Communications Server, refer to the z/OS and z/OS.e statements of direction announcement, Software Announcement 203-266, dated October 7, 2003, and the z/OS V1.7 preview announcement, Software Announcement 205-034, dated February 15, 2005.

Removal of SNA Server configuration setting LUALIASNAMES

On Windows operating systems LUALIASNAMES has been replaced by LOCALLUALIAS and PARTNERLUALIAS.

On Unix and Linux operating systems LUALIASNAMES has been replaced by PARTNERLUALIAS.

After migration if LUALIASNAMES is found in the configuration file the Client daemon will attempt to start the SNA Server connection and will generate a warning in the Client daemon log file saying that the deprecated entry LUALIASNAMES exists.

Start of change

MAXSERVERS parameter

The MAXSERVERS parameter, a setting in the CLIENT section of the configuration file for SNA and TCP/IP protocols is deprecated, and might be removed in a future release.

End of change

Support for mixed case passwords

CICS® Transaction Server for z/OS® version 2.2 and higher supports mixed-case passwords. To use mixed-case passwords, ensure that the Use uppercase security field in the Configuration Tool is cleared.

Information log

Some Client information messages are now logged. You can configure a separate log for information messages; see Changing settings for Client daemon logging.
