Configuration of the connection pool.

Attributes (5)

  • exhausted-action Specifies what happens when asking for a connection from a server's pool, and that pool is exhausted.
    • Attribute Value
    Default Value WAIT
    Type STRING
    Nillable true
    Expressions Allowed true
    Storage configuration
    Access Type read-write
    Restart Required resource-services
    Allowed Values EXCEPTION
    WAIT
    CREATE_NEW
  • max-active Controls the maximum number of connections per server that are allocated (checked out to client threads, or idle in the pool) at one time. When non-positive, there is no limit to the number of connections per server. When maxActive is reached, the connection pool for that server is said to be exhausted. Value -1 means no limit.
    • Attribute Value
    Default Value -1
    Type INT
    Nillable true
    Expressions Allowed true
    Storage configuration
    Access Type read-write
    Restart Required resource-services
  • max-wait The amount of time in milliseconds to wait for a connection to become available when the exhausted action is ExhaustedAction.WAIT, after which a java.util.NoSuchElementException will be thrown. If a negative value is supplied, the pool will block indefinitely.
    • Attribute Value
    Default Value -1
    Type LONG
    Nillable true
    Expressions Allowed true
    Unit MILLISECONDS
    Storage configuration
    Access Type read-write
    Restart Required resource-services
  • min-evictable-idle-time Specifies the minimum amount of time that an connection may sit idle in the pool before it is eligible for eviction due to idle time. When non-positive, no connection will be dropped from the pool due to idle time alone. This setting has no effect unless timeBetweenEvictionRunsMillis > 0.
    • Attribute Value
    Default Value 1800000
    Type LONG
    Nillable true
    Expressions Allowed true
    Unit MILLISECONDS
    Storage configuration
    Access Type read-write
    Restart Required resource-services
  • min-idle Sets a target value for the minimum number of idle connections (per server) that should always be available. If this parameter is set to a positive number and timeBetweenEvictionRunsMillis > 0, each time the idle connection eviction thread runs, it will try to create enough idle instances so that there will be minIdle idle instances available for each server.
    • Attribute Value
    Default Value 1
    Type INT
    Nillable true
    Expressions Allowed true
    Storage configuration
    Access Type read-write
    Restart Required resource-services

    Request Parameter Type Required Expressions Allowed Default value Description
    exhausted-action STRING false true WAIT Specifies what happens when asking for a connection from a server's pool, and that pool is exhausted.
    max-active INT false true -1 Controls the maximum number of connections per server that are allocated (checked out to client threads, or idle in the pool) at one time. When non-positive, there is no limit to the number of connections per server. When maxActive is reached, the connection pool for that server is said to be exhausted. Value -1 means no limit.
    max-wait LONG false true -1 The amount of time in milliseconds to wait for a connection to become available when the exhausted action is ExhaustedAction.WAIT, after which a java.util.NoSuchElementException will be thrown. If a negative value is supplied, the pool will block indefinitely.
    min-evictable-idle-time LONG false true 1800000 Specifies the minimum amount of time that an connection may sit idle in the pool before it is eligible for eviction due to idle time. When non-positive, no connection will be dropped from the pool due to idle time alone. This setting has no effect unless timeBetweenEvictionRunsMillis > 0.
    min-idle INT false true 1 Sets a target value for the minimum number of idle connections (per server) that should always be available. If this parameter is set to a positive number and timeBetweenEvictionRunsMillis > 0, each time the idle connection eviction thread runs, it will try to create enough idle instances so that there will be minIdle idle instances available for each server.
