Table 4. New CEMT commands
CEMT command Explanation
DISCARD PIPELINE Use the command to remove a PIPELINE from the CICS system and the CICS catalog.
DISCARD URIMAP Use the command to remove a URIMAP from the CICS system and the CICS catalog.
DISCARD WEBSERVICE Use the command to remove a WEBSERVICE from the CICS system and the CICS catalog.
INQUIRE CLASSCACHE The INQUIRE CLASSCACHE command is added to give you information about the active shared class cache in the CICS region, and report the presence of any old shared class caches that are awaiting deletion.
INQUIRE HOST Use the command to retrieve information about a particular virtual HOST in the local CICS region.
INQUIRE JVM The INQUIRE JVM command is added to enable you to identify JVMs in a CICS region and get information about their status.
INQUIRE PIPELINE Use the command to retrieve information about an installed PIPELINE.
INQUIRE URIMAP Use the command to retrieve information about URIMAP resource definitions.
INQUIRE WEBSERVICE Use the command to retrieve information about an installed WEBSERVICE.
INQUIRE WORKREQUEST The INQUIRE WORKREQUEST command is added to enable you to track EJB tasks. You can:
  • determine which transactions are associated with a single request
  • correlate all transactions associated with a single request (for example, for accounting purposes)
PERFORM CLASSCACHE The PERFORM CLASSCACHE command is added to enable you to start and reload the shared class cache, or to phase out, purge or forcepurge the shared class cache and the worker JVMs associated with it. While you are performing one of these operations, you can also change the size of the shared class cache, the JVM profile that is used for the master JVM, or the autostart status of the shared class cache.
PERFORM PIPELINE Use the command to initiate a scan of the Web service binding directory that is specified in the WSBIND attribute of the PIPELINE definition.
SET CLASSCACHE The SET CLASSCACHE command is added to enable you to set the status of autostart for the shared class cache.
SET HOST Use the command to Enable or disable a virtual HOST.
SET PIPELINE Use the command to enable or disable a PIPELINE.
SET URIMAP Use the command to enable or disable a URIMAP definition, and apply or remove redirection for a URIMAP definition.
SET WEBSERVICE Use the command to set the validation status of a WEBSERVICE.
SET WORKREQUEST The SET WORKREQUEST command is added to enable you to track EJB tasks. You can:
  • determine which transactions are associated with a single request
  • correlate all transactions associated with a single request (for example, for accounting purposes)
  • purge selected work requests
.

Table 5. Changed CEMT commands
CEMT command Option Explanation
INQUIRE CORBASERVER ENABLESTATUS These options display:
  • ENABLESTATUS displays a value indicating the current state of the CorbaServer (DISABLED, DISABLING, DISCARDING, ENABLED, or ENABLING). ENABLESTATUS replaces the STATE option, which is now obsolete.
INQUIRE DISPATCHER
ACTSSLTCBS
ACTXPTCBS
MAXSSLTCBS and
MAXXPTCBS
are added
ACTSSLTCBS displays the number of S8 mode open TCBs that are active, and MAXSSLTCBS displays the number that CICS is allowed to attach.

ACTXPTCBS displays the number of X8 and X9 mode open TCBs that are active, and MAXXPTCBS displays the number that CICS is allowed to attach.

INQUIRE DOCTEMPLATE
HFSFILE
is added
HFSFILE returns the fully-qualified name of the z/OS® UNIX System Services HFS file where the template resides.
INQUIRE PROGRAM
APIST is added
RUNTIME has a new value

APIST displays the API attribute of the installed program definition. The values are:

CICSAPI
OPENAPI

The XPLINK value for the RUNTIME option means that the program is a C or C++ program which has been compiled using the XPLINK option.

INQUIRE SYSTEM DEBUGTOOL Displays a value (DEBUG or NODEBUG) indicating whether debugging profiles will be used to select programs that will run under the control of a debugging tool.
INQUIRE SYSTEM FORCEQR has a revised description The description of FORCEQR, and its value FORCE are altered to limit its relevance to CICSAPI programs, because it does not apply to OPENAPI programs.
INQUIRE TCPIP
CRLPROFILE and
SSLCACHE
are added
CRLPROFILE displays the name of the profile that authorizes CICS to use the certificate revocation lists on an LDAP server.

SSLCACHE .displays whether CICS is using local or sysplex caching of session ids. The values are:

CICS
SYSPLEX

.

INQUIRE TCPIPSERVICE MAXDATALEN is added MAXDATALEN displays the maximum length of data that may be received by CICS as an HTTP server.
INQUIRE WORKREQUEST
WORKTYPE
has a new value.
There is a new value SOAP for the WORKTYPE option.

SET CORBASERVER
DISABLED
ENABLED
Specifies whether to enable or disable the CorbaServer.
SET DISPATCHER
MAXSSLTCBS
MAXXPTCBS
are added
MAXSSLTCBS displays the maximum number of S8 mode open TCBs that CICS is allowed to attach.

MAXXPTCBS specifies the maximum number of X8 and X9 mode open TCBs that CICS is allowed to attach.

SET JVMPOOL
TERMINATE
Deletes the shared class cache as well as the JVMs in the JVM pool.
SET PROGRAM
JVMPROFILE
For Java™ programs, this option specifies the 8-character name of a JVM profile that is to be used for the JVM in which the program runs. Any instances of this program that are currently running in a JVM with the old JVM profile are unaffected, and are allowed to finish running.
SET SYSTEM
DEBUG
NODEBUG
Specifies whether debugging profiles will be used to select programs that will run under the control of a debugging tool.
SET SYSTEM FORCEQR has a revised description The description of FORCEQR, and its value FORCE are altered to limit its relevance to CICSAPI programs, because it does not apply to OPENAPI programs.
