Action commands

Table 239 shows the action commands you can issue from the TCPIPS view. The overtype field is shown in Table 240.

The action commands and overtype fields for the TCPIPS view are available for all managed CICS systems for which TCPIPS is valid, except as noted in Table 239 and Table 240.

Table 239. TCPIPS view action commands
Primary command Line command Description
CLS CLS Closes a TCP/IP service. When this action command is used, a managed CICS system no longer accepts input from this TCP/IP service definition. Output operations from transactions in a managed CICS system that use this TCP/IP service definition are allowed to complete.
DEREG DER Causes the group name specified by the DNSGROUP attribute of this TCP/IP service definition to be deregistered from WLM. Any other TCP/IP service definitions that are in the same group (that is, share the same DNSGROUP attribute) are also deregistered
DiSCard DSC Discards a TCP/IP service definition from the CICS system where it is installed.
IMMclose IMM Requests a TCP/IP service definition to be closed immediately. When this action command is used, a managed CICS system no longer accepts input from this TCP/IP service definition. If a managed CICS system has transactions that are using the TCP/IP service definition, when this action command is used these transactions may be abnormally terminated.
OPEn OPE Opens a TCP/IP service. When this action command is used, a managed CICS system will accept input from this TCP/IP service definition.
