IBM SC34-7012-01 Transactions, Journal names and journal models, Library resources, Programs

Transient data resource definitions are installed from Resource groups defined in the CSD, as specified in the CSD group list (named on the GRPLIST system initialization parameter). Any extrapartition TD queues that require opening are opened; that is, any that specify OPEN(INITIAL). All the newly-installed TD queue definitions are written to the global catalog. All TD queues are installed as enabled.CSD definitions are installed later than the macro-defined entries because of the position of CSD group list processing in the initialization process. Any extrapartition TD queues that need to be opened are opened; that is, any that specify OPEN=INITIAL. The TDINTRA system initialization parameter has no effect in a cold start.

Note: If, during the period when CICS is installing the TD queues, an attempt is made to write a record to a CICS-defined queue that has not yet been installed (for example, CSSL), CICS writes the record to the CICS-defined queue CXRF.

Transactions

All transaction and transaction class resource definitions are installed from the CSD, and are cataloged in the global catalog.

Journal names and journal models

All journal model definitions are installed from the CSD, and are cataloged in the global catalog. Journal name definitions (including the system logs DFHLOG and DFHSHUNT) are created using the installed journal models and cataloged in the global catalog.

Note: The CICS log manager retrieves the system log stream name from the global catalog, ensuring that, even on a cold start, CICS uses the same log stream as on a previous run.

LIBRARY resources

All LIBRARY resources from a previous run are lost.

LIBRARY resource definitions are installed from resource groups defined in the CSD, as specified in the CSD group list (named on the GRPLIST system initialization parameter).

Programs

All programs, mapsets, and partitionsets are installed from the CSD, and are cataloged in the global catalog.

Start requests (with and without a terminal)

All forms of start request recorded in a warm keypoint (if the previous shutdown was normal) are lost. This applies both to START requests issued by a user application program and to START commands issued internally by CICS in support of basic mapping support (BMS) paging.

Any data associated with START requests is also lost, even if it was stored in a recoverable TS queue.

Resource definitions dynamically installed

Any resource definitions dynamically added to a previous run of CICS are lost in a cold start, unless they are included in the group list specified on the GRPLIST system initialization parameter.
