limit on the number of document handlers, and hence on the number of database
connections, active at a given time.
You specify the maximum number of document handlers for your configuration as the
value of the –quota option specified to the management client or by invoking the
SetDocumentHandlerQuota method of the management bean. Alternatively, you can
specify the quota as the value of the MaxDocumentHandlers property in the Director
properties file. Specifying a quota to the management client lets you test various quotas
without making them part of your persistent configuration; when you’ve arrived at a
value that provides adequate service and performance, use the properties file to make the
value part of your persistent configuration.
If an incoming request would cause the number of active document handlers to exceed
the configured quota, the Director releases the least recently used handler that is not in
use. When a handler is released, the time of release is recorded, and the Director logs a
message to the WLS log.
If an incoming request would cause the document handler to be exceeded, but all existing
document handlers are in use, servicing requests, the Director creates an additional
document handler, exceeding the quota. Thus the document handler quota is enforced
only when there are document handlers that are not in use.
Even with an appropriate limit on the number of document handlers, the Director can still
run out of connections if the number of ExecuteThreads in the WLS configuration is too
high. Work with the individual responsible for your WLS configuration to arrive at an
appropriate configuration.
Note: You can use connection pooling in WLS to reduce the likelihood of SQL/MX
errors. For information about this feature, see the NonStop WLS documentation set.
Deploying the Director Management Bean
The Director Management Bean does not use a properties file. Rather, it registers
itself with the appropriate NonStop WLS instance when the Director starts up. You
specify connection parameters—URL, server name, user name, and password--when
you run the management client.

The Director MBean is configured as a WebLogic startup class. As part of the WebLogic
server startup, the Director MBean registers itself with the Director WebLogic server.
1. If your Director server is not running already, start it.
2. Logon to the Director WebLogic Server using the WebLogic console.
