Pooling Profile

Field Type Description Default Value Required

Max Active

Number

Controls the maximum number of Mule components that can be borrowed from a session at one time. When set to a negative value, there is no limit to the number of components that may be active at one time. When maxActive is exceeded, the pool is said to be exhausted.

Max Idle

Number

Controls the maximum number of Mule components that can sit idle in the pool at any time. When set to a negative value, there is no limit to the number of Mule components that may be idle at one time.

Specifies the number of milliseconds to wait for a pooled component to become available when the pool is exhausted and the exhaustedAction is set to WHEN_EXHAUSTED_WAIT.

Min Eviction Millis

Number

Determines the minimum amount of time an object may sit idle in the pool before it is eligible for eviction. When non-positive, no objects will be evicted from the pool due to idle time alone.

Eviction Check Interval Millis

Number

Specifies the number of milliseconds between runs of the object evictor. When non-positive, no object evictor is executed.

Exhausted Action

Enumeration, one of:

  • WHEN_EXHAUSTED_GROW

  • WHEN_EXHAUSTED_WAIT

  • WHEN_EXHAUSTED_FAIL

Specifies the behavior of the Mule component pool when the pool is exhausted. Possible values are:

  • WHEN_EXHAUSTED_FAIL Will throw a NoSuchElementException

  • WHEN_EXHAUSTED_WAIT Will block by invoking Object.wait(long) until a new or idle object is available

  • WHEN_EXHAUSTED_GROW Will create a new Mule instance and return it, essentially making maxActive meaningless. If a positive maxWait value is supplied, it will block for, at most, that many milliseconds, after which a NoSuchElementException is thrown. If maxThreadWait is a negative value, it is blocked indefinitely.

Initialisation Policy

Enumeration, one of:

  • INITIALISE_NONE

  • INITIALISE_ONE

  • INITIALISE_ALL

Determines how components in a pool should be initialized. The possible values are:

  • INITIALISE_NONE Will not load any components into the pool on startup

  • INITIALISE_ALL Will load all components in the pool on startup

Repeatable In Memory Stream

Field Type Description Default Value Required

Initial Buffer Size

Number

The amount of memory that will be allocated to consume the stream and provide random access to it. If the stream contains more data than can be fit into this buffer, then the buffer expands according to the bufferSizeIncrement attribute, with an upper limit of maxInMemorySize.

Buffer Size Increment

Number

This is by how much the buffer size expands if it exceeds its initial size. Setting a value of zero or lower means that the buffer should not expand, meaning that a STREAM_MAXIMUM_SIZE_EXCEEDED error is raised when the buffer gets full.

Max Buffer Size

Number

The maximum amount of memory to use. If more than that is used then a STREAM_MAXIMUM_SIZE_EXCEEDED error is raised. A value lower than or equal to zero means no limit.

  • MB

  • GB

The unit in which all these attributes are expressed

Repeatable File Store Stream

Field Type Description Default Value Required

Field Type Description Default Value Required

Initial Buffer Size

Default value is 100 instances.

100

Buffer Size Increment

Number

This is by how much the buffer size expands if it exceeds its initial size. Setting a value of zero or lower means that the buffer should not expand, meaning that a STREAM_MAXIMUM_SIZE_EXCEEDED error is raised when the buffer gets full. Default value is 100 instances.
