To configure staging parameters, use the following rhino-console commands or related MBean operations.

configurestagingqueues command

Command

configurestagingqueues [maximumAge <age>] [maximumSize <size>] [threadCount
<count>]
  Description
    set some or all of the staging-queues configuration properties

Example

$ ./rhino-console configurestagingqueues maximumAge 11000 maximumSize 4000 threadCount 40
Updated staging-queue config properties:
maximumSize=4000
threadCount=40
maximumAge=11000

getstagingqueuesconfig command

Command

getstagingqueuesconfig
  Description
    get the staging-queues configuration properties

Example

$ ./rhino-console getstagingqueuesconfig
Configuration properties for staging-queues:
maximumAge=11000
maximumSize=4000
threadCount=40

MBean operations

Use the following MBean operations to configure staging queue parameters, defined on the Staging Queue Management MBean interface.

Operations

Usage

getMaximumSize
setMaximumSize

To get and set the maximum number of items permitted in the staging queue:

public int getMaximumSize()
    throws ConfigurationException;
public void setMaximumSize(int size)
    throws ConfigurationException, ValidationException;

getMaximumAge
setMaximumAge

To get and set the maximum age of items permitted in the staging queue:

public long getMaximumAge()
    throws ConfigurationException;
public void setMaximumAge(long ms)
    throws ConfigurationException, ValidationException;

Queued work items do not immediately expire if their age (measured in milliseconds) exceeds the maximum allowed. Instead, the SLEE discards them when they leave the staging queue (when it’s their turn for processing).

Tip To skip checking the age of queued items (so they can’t get "too old" for processing), you can set this parameter to -1.

getThreadCount
setThreadCount

To get and set the number of threads available for processing items on the staging queue:

public int getThreadCount()
    throws ConfigurationException;
public void setThreadCount(int threads)
    throws ConfigurationException, ValidationException;
