Administering
Administering is the activity in which you manage your CICS® systems by using the provided system management interfaces, such as CICS Explorer® . Use this information to manage
applications and workloads, change system settings in a CICSplex, and manage definitions in the CICSPlex® SM data repository.
Controlling CICS operation
While CICS is running, you can control its operation by changing CICS system definitions and by deleting and installing resource definitions. Use the CICS Explorer to control your CICS systems.
Starting and stopping CICS
This is information about how CICS starts and stops, the implications of different types of start and stop, and the actions you must take to handle them.
Administering CICSPlex SM
After you have configured your CICSPlex SM environment, you can use the CICS Explorer or Web User Interface to manage the environment.
Administering platforms and applications
Use CICS Explorer to manage and update platforms and applications. You can view, update, and remove applications from platforms. You can remove a platform from a CICSplex if it is no longer required and you can add or remove CICS regions from a region type.
Administering JVM servers
A range of CICS commands and options is available to help you administer JVM servers.
Administering Java applications
After you have enabled your Java™ applications, you can monitor the CICS region to understand how the applications are performing. You can tune the environment to optimize the performance of the application.
Administering BTS
You can operate BTS in a single CICS region. However, CICS business transaction services are sysplex-enabled. For example, you can use workload separation to ensure that processes of the same process-type are handled by a particular set of regions, and you can use workload routing to route activity requests across a set of regions.
Administering data tables
Information about the operational aspects of data tables.
Administering connections between CICS systems
You can manage definitions of MRO, IPIC , and APPC parallel-session connections between CICS Transaction Server for z/OS® systems using connection definitions.
Administering connections to other systems
After you have set up your connections to other systems, such as Db2® , IMS, and IBM® MQ , you can use CICS to manage those connections.
Administering restart and recovery
Before you begin to plan and implement resource recovery in CICS, you should understand the concepts involved, including units of work, logging and journaling.
Administering output from a CICS region
Output written to the CICS transient data queues appears in JCL DDNAMEs that are allocated to a CICS region. An example of this transient data queue is CSSL, which is defined as an extra partition transient data queue and assigned to DDNAME MSGUSR. Over time the amount of data written to the data set can become very large and the data set needs to be deallocated from the region in order to reduce JES spool usage. Here are some recommendations for you to consider.
