The following parameters must be defined in the start-up jobstream for
a CICS region that supports IIOP:
- JCL parameter
-
- REGION
- 1000M minimum is recommended
- CICS system initialization parameters
-
- EDSALIM
- 500M minimum is recommended.
- IIOPLISTENER
-
- Specify IIOPLISTENER=YES if the CICS region is an IIOP listener region,
or a combined listener and application owning region (AOR).
- Specify IIOPLISTENER=NO if the CICS region is an IIOP application owning
region. TCPIPSERVICE definitions installed in the region that specify PROTOCOL(IIOP)
cannot be opened.
- JVMPROFILEDIR
- Set to the HFS directory containing the JVM profiles that you are using
for your applications. Enabling CICS to locate the JVM profiles and JVM properties files tells you
how to do this.
- KEYRING
- Required if you are using Secure Sockets Layer (SSL) authentication with
certificates registered to RACF®.
- MAXJVMTCBS
- Specify the number of JVMs that your CICS region can support. The CICS® Performance Guide tells
you how to work out an appropriate setting for the MAXJVMTCBS system initialization
parameter.
- TCPIP
- Set to YES.
- DD statements for CICS datasets
- Sample local VSAM data set definitions are provided in the CICS-supplied
RDO group DFHEJVS. These data sets must be authorized with RACF for UPDATE
access. See the CICS RACF Security
Guide.
- DFHEJDIR
- A recoverable shared file containing the request streams directory. This
can be a VSAM file or a coupling facility data table. CICS supplies sample
JCL to help you create this file, in the DFHDEFDS member of the SDFHINST library.
Note: In
most cases, the RECORDSIZE parameter in the supplied JCL should not require
modification. However, if you intend to install more than 40 CorbaServers
in your logical EJB/CORBA server, see
Specifying the RECORDSIZE of DFHEJDIR and DFHEJOS.
- DFHEJOS
- A non-recoverable shared file used by CICS when CorbaServers are installed
and to store stateful session beans that have been passivated. This can be
a VSAM file or a coupling facility data table. CICS supplies sample JCL to
help you create this file, in the DFHDEFDS member of the SDFHINST library.
Note: In
most cases, the RECORDSIZE parameter in the supplied JCL should not require
modification. However, if you intend to install more than 40 CorbaServers
in your logical EJB/CORBA server, see
Specifying the RECORDSIZE of DFHEJDIR and DFHEJOS.
