5.6 Advertising and Unadvertising Services
When a server is booted, it advertises the services it offers
based on the values specified for the CLOPT parameter
in the configuration file.
Note:
The services that a server may advertise are initially defined when thebuildserver command is executed. The -s option allows a comma-separated list of services to be specified. It also allows you to specify a function with a name that differs from that of the advertised service that is to be called to process the service request. Refer to the buildserver(1) in the Oracle Tuxedo Command Reference for more information.
The default specification calls for the server to advertise all services with which it was built. Refer to the UBBCONFIG(5) or servopts(5) reference page in the File Formats, Data Descriptions, MIBs, and System Processes Reference for more information.
Because an advertised service uses a service table entry in the bulletin board, and can therefore be resource-expensive, an application may boot its servers in such a way that only a subset of the services offered are available. To limit the services available in an application, define the CLOPT parameter, within the appropriate entry in the SERVERS section of the configuration file, to include the desired services in a comma-separated list following the -s option. The -s option also allows you to specify a function with a name other than that of the advertised service to be called to process the request. Refer to the servopts(5) reference page in the File Formats, Data Descriptions, MIBs, and System Processes Reference for more information.
An Oracle Tuxedo application administrator can use the advertise and unadvertise commands of tmadmin(1) to control the services offered by servers. The tpadvertise() and tpunadvertise() functions enable you to dynamically control the advertisement of a service in a request/response or conversational server. The service to be advertised (or unadvertised) must be available within the same server as the service making the request.
