Cisco Systems S/390 manual Common Inet Sockets in OpenEdition, RS6000, Vtam Release

Page 25

Installation Requirements

DB2/CONNECT V5 requires Fix Pack WR09014. Do not apply Fix Pack WR09024.

Common Inet Sockets in OpenEdition

You must install the APAR OW20620 in order to use Common Inet sockets in OpenEdition.

RS6000

You must install the RS/6000 patch U432867 to use the CLAW driver. With earlier RS/6000 maintenance, MVS error recovery problems can occur.

VTAM Release 3.3

VTAM Release 3.3 users must apply PTF UY67100 or UY69746, or their equivalent. If this is not possible, contact Cisco TAC and request APAR MB18602. If the PTFs or APAR are not applied, problems can occur handling control vector X’5F’ and cause connection errors.

MVS/ESA Release 5.1 Considerations

Interlink 3722 users must install the latest release of the CETI microcode. Interlink 3762 users must install the latest release of the ECA CETI microcode. The CETI driver may terminate at startup if you are using earlier releases.

Novell LAN Workplace

We recommend that you apply Novell fixes LWP41N and LWP168 (to correct an FTP hang condition). These fixes are available on NetWire.

Walker, Richer, & Quinn Software

If you are using software from Walker, Richer, & Quinn, we recommend that you install version

2.1.2or above of Reflection 8+ (for DOS using IBM 3270) and Version 2.2 of WRQNET TCP/IP. Users of earlier releases can experience a tn3270 hang condition.
