  Description
 

PTF JN00616
PTF JN00616 for Expedite Base/MVS 4.5 will be available on or after August 22, 2003. This PTF was tested on both OS/390® 2.10 and z/OS® 1.2 and contains program fixes for the following:

  • Corrupted data can be written to the output file when restarting a session using checkpoint-level, file-level, or user-level recovery.
  • A write failure (21810) can occur on the RCVWORK file when restarting a session using checkpoint-level, file-level, or user-level recovery.
  • Prior to PTF JN00616, when Expedite Base/MVS users issued the TCPCOMM command to connect to Information Exchange, Expedite Base/MVS would search through a list of host and port pairs, such as IETCPHOSTn/IETCPPORTn to make the connection. If the first host and port pair in the list failed to make a connection to Information Exchange, Expedite Base/MVS would issue an error and the connection would fail, even if Expedite Base/MVS found a subsequent pair to make a successful connection.

    Using PTF JN00616, Expedite Base/MVS users can achieve a connection with the TCPCOMM command, even if the connection to the first host and port pair failed. Users are still notified of the connection error, but this error no longer prohibits connection to Information Exchange.

Operating System Support Update
Expedite Base/MVS 4.5 is supported on z/OS 1.2. Users of checkpoint-level, file-level, or user-level recovery should consider upgrading to PTF JN00616. Otherwise, no program update is required to support z/OS 1.2. Expedite Base/MVS 4.5 is supported on the following operating system releases:

  • OS/390 2.10
  • z/OS 1.2 (newly added)
