modifySIBEngine command

Use the modifySIBEngine command to modify the properties of a messaging engine for a service integration bus member.

Para executar o comando, utilize o objeto AdminTask do cliente de script wsadmin.

[IBM i][IBM i]O cliente de script wsadmin é executado do Qshell. [IBM i]Para obter informações adicionais, consulte Configurando o Qshell para Executar Scripts do WebSphere Usando o Script wsadmin.

A ajuda da linha de comandos é fornecida para comandos do barramento de integração de serviços:
  • Para obter uma lista dos comandos de barramento de integração de serviços disponíveis no Jython e uma breve descrição de cada comando, digite o seguinte comando no prompt wsadmin:

    print AdminTask.help('SIBAdminCommands')

  • Para obter ajuda de visão geral sobre um determinado comando, digite o seguinte comando no prompt wsadmin:

    print AdminTask.help('command_name')

Após utilizar o comando, salve suas alterações na configuração principal, utilizando o seguinte comando:

AdminConfig.save()

Purpose

This command modifies the properties of a messaging engine.

Target object

A messaging engine.

Required parameters

-bus busname
The name of the service integration bus on which the bus member is configured. You can use the listSIBuses command to list the names of existing buses.

Conditional parameters

-node nodename -server servername
To change properties of a messaging engine for an application server as a bus member, specify both the name of the node on which the server runs and the name of the server.
-cluster cluster
To change properties of a messaging engine for a server cluster as a bus member, specify the name of the cluster.
-engine enginename
If the bus member has only one messaging engine, you do not need to specify the engine name. If the bus member has several messaging engines, you must specify the name of the engine for which you want to change properties.

Optional parameters

-description text
An optional description for the messaging engine, for administrative purposes.
-initialState STARTED | STOPPED
The initial state determines whether the messaging engine is started automatically when the server or server cluster is started.
Parado
Quando o servidor de aplicativos associado é iniciado, o mecanismo do sistema de mensagens é parado e não fica disponível para processar mensagens.
Started
Quando o servidor de aplicativos associado é iniciado, o mecanismo do sistema de mensagens é iniciado e disponibilizada para processar mensagens.
-highMessageThreshold number
The maximum total number of messages that the messaging engine can place on its message points.

When the messaging engine is created, the high message threshold of the bus is used to set the default value for this property. When a message point is created on this messaging engine, the value of this property is used to set the default high message threshold for the message point.

-restrictLongDBLock TRUE | FALSE
A parameter that specifies whether the active messaging engine must retain long running locks on the SIBOWNER table in the database. When this option is selected, the messaging engine establishes a lock over the database only for short durations. In the event of the active messaging engine not responding to the database, the standby messaging engine will be able to take ownership of the database because the active messaging engine only holds short duration locks. This parameter has two possible values:
TRUE
Restrict long running locks on the database.
FALSE
Do not restrict long running locks on the database.

Use this parameter if the -dataStore parameter is specified.

Important: Although the property is selected, the property will not be effective until the database tables are upgraded using the sibDBUpgrade command for WebSphere® Application Server Versão 9.0 and later.

Example

wsadmin>AdminTask.showSIBEngine('[-bus bus1 -node node01 -server server1 
-engine node01.server1-bus1 ]')
'{initialState=STARTED, targetGroups=[], name=node01.server1-bus1, 
highMessageThreshold=50000, messageStoreType=FILESTORE, uuid=56F8FE11AB84188D, 
busName=bus1, busUuid=6DF19B02BC879BD1}'

wsadmin>AdminTask.modifySIBEngine('[-bus bus1 -node node01 -server server1 
-engine node01.server1-bus1 -initialState STOPPED ]')

wsadmin>AdminTask.showSIBEngine('[-bus bus1 -node node01 -server server1 
-engine node01.server1-bus1 ]')
'{initialState=STOPPED, targetGroups=[], name=node01.server1-bus1, 
highMessageThreshold=50000, messageStoreType=FILESTORE, uuid=56F8FE11AB84188D, 
busName=bus1, busUuid=6DF19B02BC879BD1}'
