Using the Gateway Administrative Server, GWADM(5)
The gateway administrative server, GWADM(5), is a BEA Tuxedo-supplied server that provides administrative functions for a Domains gateway group. The main functions of the GWADM server include the following:
The GWADM server advertises a service name based on the local domain name (the value of the LDOM keyword in the BDMCONFIG). The dmadmin command uses this service to retrieve information from all active gateway groups or from a specific gateway group.
The GWADM server must be defined in the SERVERS section of the TUXCONFIG file. It should not be part of the MSSQ used by the gateways associated with the group and it must not have a reply queue, that is, REPLYQ=N must be specified. It must be the first server booted within the gateway group; that is, either (a) it must have a SEQUENCE number, or (b) it must be defined ahead of the gateway servers.
The GWADM server requires the existence of a DMADM server. Specifically, a DMADM server must be booted before that GWADM is booted.
The GWADM server must create the shared memory required by the gateway group to populate the configuration tables with information received from the DMADM server. The GWADM server uses IPC_PRIVATE with shmget and stores the ipckey returned in the shmid field of its registry entry in the bulletin board. Gateways can obtain the ipckey by retrieving the GWADM registry entry and checking the shmid field.
