The WLE and BEA TUXEDO systems allow you to make changes to your configuration without shutting it down. Without inconveniencing your users, you can suspend or resume interfaces or services, advertise or unadvertise services, and change interface or service parameters (such as This chapter discusses the following topics:
LOAD
and PRIORITY
). If your configuration specifies interfaces or services as AUTOTRAN
, it is also possible to change the timeout value associated with such transactions. Thus, you can adjust your system to reflect either current or expected conditions.
You have a choice of two methods for making changes to your system while the system is running:
Dynamic Modification Methods
Because it is a graphical user interface, the BEA Administration Console is simpler to use than the For instructions on using the Instructions for dynamically modifying your system through This section provides procedures for making the following types of changes, throughtmadmin
command interpreter. If you prefer using a GUI, bring it up on your screen as soon as you are ready to begin an administrative task. The graphics and detailed procedures will guide you through any task you need to perform.
tmadmin
command interpreter, see Chapter 8, "Monitoring a Running System."

Procedures for Dynamically Modifying Your System

This section provides instructions for suspending and resuming services and servers, and describes the results of these operations.
Note:
The execution of the To suspend a server or a service, enter the The Suspending and Resuming Services (BEA TUXEDO Servers)
suspend
and resume
commands described in this section have minimal impact on the BEA TUXEDO system resources when compared with the resources gained by suspending a server.
Suspending Services
suspend
(or susp
) command, as follows.
prompt> tmadmin
> suspsuspend
command marks as inactive one of the following:
After you have suspended a service or a server, any requests remaining on the queue are handled, but no new service requests are routed to the suspended server. If a group ID/server ID combination is specified and it is part of an MSSQ set, all servers in that MSSQ set become inactive for the services specified.
To resume a server or a service, enter the The Resuming Services
resume
(or res
) command, as follows.
prompt> tmadmin
> resresume
command undoes the effect of the suspend
command: it marks as active for the queue one of the following:
If, in this state, the group ID or the server ID is part of an MSSQ set, all servers in that MSSQ set become active for the services specified.
This section provides instructions for advertising and unadvertising services and servers, and describes the results of these operations.
To advertise a service, enter the following command.
Note:
Although a service must be suspended before it may be unadvertised, you do not need to "unsuspend" a service before re-advertising it. If you simply advertise a service that has been suspended and unadvertised previously, the service will be unsuspended.
To unadvertise a service, complete the following procedure.
Advertising and Unadvertising Services (BEA TUXEDO Servers)
Advertising Services
adv [{[-q queue_name] | [-g grpid] [-i srvid]}] service
Unadvertising Services
Note:
Unadvertising has more drastic results than suspending because when you unadvertise a service, the service table entry for that service is deallocated and the cleared space in the service table becomes available to other services.
unadv [{[-q queue_name] | [-g grpid] [-i srvid]}] service
You can change the service and interface parameters for the following:
The following table lists the names of the parameters for which you can change values dynamically, along with the commands for changing them.
You must specify a service name (after the
