  • IBM z/VM versions 5.3 and 5.4
  • IBM z/VSE version 4.2.1

Model 204 Release V7R4

Release V7.4 is supported on the following operating system environments:

  • IBM z/OS versions 1.09 through 2.1
  • IBM z/VM versions 5.3 and 5.4
  • IBM z/VSE version 4.2.1

Model 204 Release V7R1

Release V7.1 is supported on the following operating system environments:

  • IBM z/OS versions 1.09 through 2.1
  • IBM z/VM versions 5.3 and 5.4

z/OS 2.1 compatibility issues

In Model 204 versions 7.5 and lower, Horizon TCP applications sending data larger than 16K might get the following error:

M204.1254: User language statement is invalid in this conversation state

This error occurs under z/OS version 2.1 because the TCP Default Send Buffer Size (DefaultSndBufSize) was increased to 65536 (from 16384 in earlier versions).

Solution

  • Model 204 v7.5:
    Apply zap 75Z226.
  • Model 204 v7.4:
    Currently fixed by zap 74Z4552. Contact Model 204 support.
  • Model 204 v7.1 (and lower):
    Workaround: Set z/OS 2.1 TCP DefaultSndBufSize to 16384.
