If you define new resource definitions and install them dynamically, ensure the
group containing the resources is added to the appropriate group list.
Monitoring and statistics
The initial status of CICS monitoring is determined by the monitoring system
initialization parameters (MN and MNxxxx).
The initial recording status for CICS statistics is determined by the statistics system
initialization parameter (STATRCD). If STATRCD=ON is specified, interval
statistics are recorded at the default interval of every three hours.
Terminal control resources
All previous terminal control information stored in the global catalog warm
keypoint is lost.
Terminal control resource definitions are installed as follows:
VTAM devices
All VTAM terminal resource definitions are installed from the CSD. The
definitions to be installed are specified in groups named in the CSD group
list, which is specified by the GRPLIST system initialization parameter. The
resource definitions, of type TERMINAL and TYPETERM, include
autoinstall model definitions as well as explicitly defined devices.
Connection, sessions, and profiles
All connection and sessions definitions are installed from the CSD. The
definitions to be installed are specified in groups named in the CSD group
list, which is specified by the GRPLIST system initialization parameter. The
connections and sessions resource definitions include those used for APPC
autoinstall of parallel and single sessions, as well as explicitly defined
connections.
TCAM and sequential devices
All TCAM and sequential (BSAM) device terminal resource definitions are
installed from the terminal control table specified by the TCT system
initialization parameter. CICS loads the table from the load library defined
in the DFHRPL library concatenation. CICS TS for z/OS, Version 4.1
Note: supports only remote TCAM terminals—that is, the only TCAM
terminals you can define are those attached to a remote, pre-CICS TS 3.1,
terminal-owning region by TCAM/DCB.
Resource definitions for TCAM and BSAM terminals are not cataloged at
install time. They are cataloged only in the terminal control warm keypoint
during a normal shutdown.
Committing and cataloging resources installed from the CSD
CICS has two ways of installing and committing terminal resource definitions.
Some resource definitions can be installed in groups or individually and are
committed at the individual resource level, whereas some VTAM terminal control
resource definitions must be installed in groups and are committed in “installable
sets”.
Single resource install
All except the resources that are installed in installable sets are committed
individually. CICS writes each single resource definition to the global
catalog as the resource is installed. If a definition fails, it is not written to
the catalog (and therefore is not recovered at a restart).
