SALT – Service Architecture Leveraging Tuxedo
Configuring the Tuxedo web services
In this section, we will discuss most of the web-services-related configuration to
set up your SALT environment, such as the UBBCONFIG file, the Tuxedo metadata
repository, configuring native or external web services, the deployment file, and
compiling the SALT configuration.
The UBBCONFIG file
We all know the importance of the UBBCONFIG file for a Tuxedo application. To
incorporate SALT in your application, you need to include some entries for SALT
components in this file; some of them are musts and some of them are optional, as
described here:
• The TMMETADATA server in the *SERVERS section (required):
TMMETADATA is the server provided by Tuxedo. It has the TMMETAREPOS
service, which processes requests to retrieve or update the Tuxedo service
metadata repository information. For example:
*SERVERS
TMMETADATA
SRVGRP=MyGrp SRVID=202 RESTART=Y MAXGEN=4
GRACE=2500 CLOPT="-A -- -f /usr/MyApps/Metadata"
• The GWWS servers in the *SERVERS section (required): This is the web
service gateway server that we discussed a couple of times. The GWWS server
refers to the SALTCONFIG file during boot up, so the environment variable
SALTCONFIG must be set prior to starting up this GWWS server. Also, the
TMMETADATA server should be booted up before GWWS, because this server calls
the services of TMMETADATA. One or more GWWS servers can be configured in
the same Tuxedo domain, but each GWWS server must have a unique instance
ID using the -i option. For example:
*SERVERS
GWWS
SRVGRP= MyGrp SRVID=210
SEC_PRINCIPAL_NAME="gwws_ PASSWD " optional(#4 points
below)
SEC_PRINCIPAL_PASSVAR="gwws_PASSWD" optional(#4 points
below)
CLOPT="-A -- – i MyGWWS1"
