Overview:
IMS™ Queue Control Facility for z/OS® is an IMS queue management tool that manipulates the local, live IMS message queues in both the shared and nonshared queues environments. It can query, browse, load, unload and reprocess messages.
IMS Queue Control Facility prevents queue overflow conditions and restores messages on the message queues for processing. For shared queues environments, this includes recovery of the full function message queue (MSGQ) structure in the Coupling Facility without the need for Common Queue Server logging.
Highlights
- Ensure IMS and Shared Message Queues are secured
- Requeue processed and unprocessed IMS messages
- Recover messages after system outages and maintain IMS queues
Features:
Queue overflow protection
IBM® IMS™ Queue Control Facility for z/OS® monitors message queue usage to prevent overflow. It analyzes the message queue usage to send alerts or to act to prevent the excessive queue usage from continuing.
Message processing
IMS Queue Control Facility processes selected messages based on the criteria that you specify in control statements. It produces an output data set and a data report that includes quantitative information about the selected messages.
Recovery and maintenance functions
IMS Queue Control Facility helps you perform recovery and maintenance tasks, such as message queue recovery after either a planned or unplanned system outage. It provides application recovery when it is practical for both shared and nonshared queues environments. It allows you to query, browse, unload and load IMS messages from, or to, the IMS message queues.
Message requeuing
In the nonshared queues environment, the IMS Queue Control Facility gets messages that need to be requeued from the SLDS or the IMS queue manager message queues. In the shared queues environment, IMS Queue Control Facility gets messages from the cold queue. For shared queues, IMS Queue Control Facility also retrieves messages that need to be requeued from SLDS and CQS structure recovery datasets (SRDS.)
Queue maintenance
For both shared and nonshared queues environments, IMS Queue Control Facility helps you examine the queues and remove only those messages that are no longer needed.
TSO client/ISPF interface
The IMS Queue Control Facility TSO client (ISPF interface) helps you select the server and IMS subsystem to be used. You can view the IMS environment that you are using and your local queue status. It allows you to query messages and list the destinations of the queued messages. You can unload messages from the IMS message queues and load or reload messages onto it. You can also maintain the tables that are associated with queue overflow protection for a nonshared queues environment.
Benefits:
Run on multiple CECs
Allows different IMS Queue Control Facility functions to run on multiple CECs within a sysplex with other IMS Queue Control Facility servers.
Automatically detects cold and warm starts
Automatically identifies cold and warm starts, requeuing messages before a cold start and offloading or requeuing from the dead letter queue after a warm start, helping ensure minimal disruption.
Better monitor messages
Provides a Queue Space Utilization Notification mechanism that lets you define up to ten areas of the total queue space to monitor for small or large messages.
