Mainframe Enablers enhanced zDP’s usability and monitoring capabilities. Some of the new features include:
- The QUERY SNAPSET command with the SNAPSET option provides a new entry in the output called ‘RDP Cache Utilization’ percentage. This information allows customers to monitor their PowerMax Replication Data Pointers (RDP) usage. In the event a customer’s RDP usage exceeds a threshold, customers should work with Dell support to look at reducing the RDP usage.
- Create VDG ISPF panels (via existing zDP ISPF panels) or batch JCL statements add three new parameters on the Versioned Data Group (VDG).
- RDP Cache Util(ww,cc) – ‘ww’ is a percentage for when warning messages should be sent to z/OS. ‘cc’ is a percentage when the RDP threshold reaches a critical level and messages will be sent to z/OS.
- SMF rec number – This permits the customer to set a SMF record number for zDP. SMF records are cut for that VDG at the beginning of each cycle. This time is specified in the ‘Cycle Time’ input parameter
- TRACKS – Provides additional output for your VDG for all total changed and unique tracks within the VDG.
Note: Understand that turning TRACKS(Y) will create a lot of data for the VDG.
- TERMINATE ALL command available via zDP ISPF panels and batch JCL statements. This command enables customers to terminate multiple zDP snapsets with one statement. The ability to ensure the customer chooses to do this with a confirmation message in the zDP ISPF panels or a WTOR message in SYSLOG (if running in batch mode) is provided.
- If a zDP snapset fails during the ACTIVATE command, zDP automatically cleans up and terminates the snapsets.
