IASP Enhancements for IBM i 7.4 TR 3 and IBM i 7.3 TR 9 and IBM i 7.2 PTF

Previously, when necessary to acquire a port for connection, geographic mirroring would use a random port number. This could cause problems for system administrators when implementing Quality of Service (QoS) and security for their environment. Support has been added to the WRKSRVTBLE (Work with Service Table Entries) command to allow the specification of a particular port number for use by geographic mirroring.

IBM i 7.4 PTF:  MF67632  (also included in PTF Group SF99666 - Level 5)

IBM i 7.3 PTF:  MF67881 (also included in PTF Group SF99876 - Level 13)

IBM i 7.2 PTF:  MF67883 (also included in PTF Group SF99776 - Level 16)

Prior to this technology refresh, if there was an IFS directory in SYSBAS and there was a vary on of an IASP whose name was the same as that IFS directory, the result was that the vary on of the IASP would complete successfully, but the IFS directory in the IASP was not visible or accessible to anyone. The recommended work-around (vary off the IASP, delete, or rename the existing IFS directory in SYSBAS, and vary on the IASP again) could take a lot of time, and the user may not have been aware of the recommended action to take to correct the situation. IBM i 7.4 TR 3 and IBM i 7.3 TR 9 add an enhancement that detects the presence of an IFS directory in SYSBAS with the same name as the IASP during the IASP vary on process. The system administrator is notified about the situation through an inquiry message so that appropriate action can be taken, such as renaming, moving, or deleting the existing IFS directory in SYSBAS, or forcing a mount of the IFS directory in the IASP over the IFS directory in SYSBAS.
