CICS Transaction Gateway V5 The WebSphere ... - IBM Redbooks

150 CICS Transaction Gateway V5
CICSCLI=/ctg/scsctg5/CTG.INI
CTG_RRMNAME=CCL.CTG.IBM.UA
CTGSTART_HOME=/usr/lpp/ctg500/ctg/bin
The CICS TG V5 supplies a new and somewhat complex ctgenvvarsamp file as a
sample of the ctgenvvar file used for controlling of environment variables. This
new ctgenvvar will override variables set in other places, such as STDENV. To
understand this new ctgenvvar file, you will need to be familiar with UNIX System
Services and Korn shell scripting. If you are not, we suggest you use a simple
version, such as the one we used (shown in Example 7-8), which does not
override variables set in other places.

Following is a summary of the variables you are likely to have to set:
► DFHJVPIPE
The value specified here should match the NETNAME in the CICS connection
definition to be used for an EXCI connection using a specific pipe. The default
connection name in the IBM-supplied group DFH$EXCI is EXCS, which has a
NETNAME of BATCHCLI. We created our own connection definition, and
used a NETNAME of SCSCTG5.
► DFHJVSYSTEM
The syntax of this variable is DFHJVSYSTEM_nn=aaaaaaaa literal, where:
– nn = 0 to 99
– aaaaaaaa = the APPLID of the CICS region
– literal = a description of the CICS region
Note the setting of this variable is optional, and only affects the result of the
ECIRequest.listSystems() method and does not affect which CICS regions
you can connect to.
