New system initialization parameters

Table 3 shows new system initialization parameters.

The default values for these parameters are designed to have minimal impact when you are migrating from an earlier release of CICS®.

Table 3. New system initialization parameters
Keywords Operands Explanation
AIBRIDGE {AUTO|YES} Specifies whether the autoinstall user-repaceable program (URM) is called for bridge facilities (YES) or whether they are defined automatically by CICS (AUTO).
BRMAXKEEPTIME {86400|timeout} Specifies the maximum time in seconds that bridge facilities are kept when unused, with a default value ( and upper limit ) of 24 hours.
CLINTCP {437|codepage} Specifies the default client code page to be used by the DFHCNV data conversion table but only if the CLINTCP parameter in the DFHCNV macro is set to SYSDEF.

For more information, see the CICS System Definition Guide.

CRLSERVER servername: portnumber Specifies the name of the LDAP server and the port number that contains the certification revocation lists (CRLs). Specifying this parameter means that CICS checks each client certificate during the SSL negotiation for a revoked status. If the certificate is revoked, CICS closes the connection immediately.

For more information, see the CICS System Definition Guide.

DEBUGTOOL {NO|YES} Specifies whether debugging profiles will be used to select programs that will run under the control of a debugging tool.

For more information, see the CICS System Definition Guide

EJBROLEPRFX ejbrole-prefix Specifies a prefix to qualify the security role defined in an enterprise bean's deployment descriptor.
IIOPLISTENER {YES|NO} Specifies whether the CICS region is to function as an IIOP listener region.
INFOCENTER {infocenter_url } Specifies the Universal Resource Locator (URL) of the root of the CICS Information Center directory structure.

For more information, see the CICS System Definition Guide

JVMCCPROFILE {DFHJVMCC|profile} Specifies the JVM profile to be used for the master JVM that initializes the shared class cache.

For more information, see the CICS System Definition Guide.

JVMCCSIZE {24M|number} Specifies the size of the shared class cache on an initial or cold start of CICS.

For more information, see the CICS System Definition Guide.

JVMCCSTART {AUTO|YES|NO} Determines whether or not the shared class cache is started during CICS initialization, and sets the status of autostart for the shared class cache.

For more information, see the CICS System Definition Guide.

JVMLEVEL0TRACE, JVMLEVEL1TRACE, JVMLEVEL2TRACE, JVMUSERTRACE {option} Specify the default options for the JVM trace levels.

For more information, see the CICS System Definition Guide.

JVMPROFILEDIR

directory}

 
(Take note that the operand above is entered without spaces, or line breaks.)
Specifies the name of an HFS directory that contains the JVM profiles for CICS.

For more information, see the CICS System Definition Guide.

KEYRING keyring_name Specifies the name of the key ring defined in the security manager's database (for example, as defined by the RACF® RACDCERT ADDRING command).
LOCALCCSID {037|CCSID} Specifies the default CCSID for the local region.

The CCSID is a value of up to 8 characters. If CCSID value is not specified, the default LOCALCCSID is set to 037.

For more information, see the CICS System Definition Guide.

MAXJVMTCBS {5|number} Specifies the maximum number of J8 mode open TCBs that can exist concurrently in the CICS region.The pool of J8 mode open TCBs is reserved exclusively for Java™ programs defined with JVM(YES).

number can be any value in the range 1 through 999.

MAXSOCKETS {65535|number} Specifies the maximum number of IP sockets that can be managed by the CICS sockets domain.

Note that the default value, and any explicit value, is conditional upon the authorization of the CICS region user ID. If the user ID is not defined to UNIX system services as a superuser, the default is restricted to the value specified on the MAXFILEPROC parameter in the BPXPRMxx of SYS1.PARMLIB.

MAXSSLTCBS {8|number} Specifies the maximum number of S8 TCBs that can run in the SSL pool. The default is 8, but you can specify up to 1024 TCBs.

For more information, see the CICS System Definition Guide.

MAXXPTCBS {5|number} Specifies the maximum number, in the range 1 through 999, of open X8 and X9 TCBs that can exist concurrently in the CICS region.

For more information, see the CICS System Definition Guide.

RSTSIGNOFF {NOFORCE|FORCE} Specifies whether all users signed on to a CICS region are allowed to remain signed on following a persistent sessions restart or an XRF takeover (XRFSOFF is obsolete).
RSTSIGNTIME {500|hhmmss} Specifies the time-out delay interval for signon retention during a persistent sessions restart or an XRF takeover (XRFSTIME is obsolete).
SRVERCP {037|codepage} Specifies the default server code page to be used by the DFHCNV data conversion table but only if the SRVERCP parameter in the DFHCNV macro is set to SYSDEF.

For more information, see the CICS System Definition Guide.

SSLCACHE {CICS| SYSPLEX} Specifies whether SSL is to use the local or sysplex caching of session ids.

For more information, see the CICS System Definition Guide.

STATEOD {0|hhmmss} Specifies the end-of-day time for interval statistics collection.
STATINT {030000|hhmmss} Specifies the interval for statistics collection.
XEJB {YES|NO} Specifies whether support of security roles is to be enabled.
