Managing IMS resources by using TSO SPOC

The TSO SPOC application provides a set of resource management panels to help you manage IMS resources. You can use TSO SPOC to query IMS resources and, if dynamic resource definition (DRD) is enabled in your IMS systems, you can also use the TSO SPOC panels to create, delete, export, import, and update IMS resources.

You can access the panels from the Manage Resources menu in the TSO SPOC application or by selecting the Manage Resources option directly from the IMS Application Menu.

Querying IMS resource information by using TSO SPOC

You can query the attributes and status of IMS resources as maintained in each IMS system or across the IMSplex. The information returned for IMS resources can include:

  • The status of resources as set by commands and maintained locally by IMS systems
  • The status of resources as set by commands and maintained globally across the IMSplex by Resource Manager (RM)
  • The status of resources as set in the DBRC RECON data set
  • The attributes of various IMS resources as set by system definition macros or by DRD commands
  • The attributes status and attributes information about an IMSRSC repository

Creating, deleting, exporting, importing, and updating IMS resources by using TSO SPOC

Before you can create, delete, export, import, or update IMS resources through TSO SPOC by using the dynamic resource definition commands, you should be aware of the following points:

  • You must enable DRD in the target IMS systems.
  • Changes made to IMS resources are not saved across an IMS cold start until they are exported to the resource definition data set (RDDS) or the repository. If a cold start or emergency restart with the COLDSYS parameter occurs before an export is performed, any changes to resource definitions are lost.
  • After creating an application program or database by using the CREATE command, you must further define the application program or database, as well as its relationships to other resources, by running the appropriate generation utility, such as the Database Description Generation (DBDGEN) utility or the Program Specification Block Generation (PSBGEN) utility. You must perform an ACBLIB or ACBMBR online change to ensure that the created or modified DBD or PSB resources are available to the IMS system.

The IMS resources and resource descriptors that you can create, delete, export, import, and update in DRD-enabled systems include:

  • Application programs
  • Databases
  • Fast Path routing codes
  • Transactions
  • Change list (delete only)
