Description

The `create-connector-connection-pool` subcommand defines a pool of
connections to an enterprise information system (EIS). The named pool
can be referred to by multiple connector resources. Each defined pool is
instantiated at server startup, and is populated when accessed for the
first time. If two or more connector resources point to the same
connector connection pool, they are using the same pool of connections
at run time. There can be more than one pool for a connection definition
in a single resource adapter.

A connector connection pool with authentication can be created either by
using a `--property` option to specify user, password, or other
connection information, or by specifying the connection information in
the XML descriptor file.

This subcommand is supported in remote mode only.

Options

asadmin-options::
  Options for the `asadmin` utility. For information about these
  options, see the link:asadmin.html#asadmin-1m[`asadmin`(1M)] help page.
`--help`::
`-?`::
  Displays the help text for the subcommand.
`--associatewiththread`::
  Specifies whether a connection is associated with the thread to enable
  the thread to reuse the connection. If a connection is not associated
  with the thread, the thread must obtain a connection from the pool
  each time that the thread requires a connection. Possible values are
  as follows: +
  `false`;;
    A connection is not associated with the thread (default).
  `true`;;
    A connection is associated with the thread.
`--connectiondefinition`::
  The name of the connection definition.
`--creationretryattempts`::
  Specifies the maximum number of times that the server retries to
  create a connection if the initial attempt fails. +
  Default value is 0, which specifies that the server does not retry to
  create the connection.
`--creationretryinterval`::
  Specifies the interval, in seconds, between successive attempts to
  create a connection. +
  If `--creationretryattempts` is 0, the `--creationretryinterval`
  option is ignored. Default value is 10.
`--description`::
  Text providing descriptive details about the connector connection
  pool.
`--failconnection`::
  If set to true, all connections in the pool are closed if a single
  validation check fails. This parameter is mandatory if the
  `--isconnectvalidatereq` option is set to true. Default value is
  false.
`--idletimeout`::
  The maximum time that a connection can remain idle in the pool. After
  this amount of time, the pool can close this connection. Default value
  is 300.
`--isconnectvalidatereq`::
  If the value is set to true, the connections will be checked to see if
  they are usable, before they are given out to the application. Default
  value is false.
`--lazyconnectionenlistment`::
  Specifies whether a resource to a transaction is enlisted only when a
  method actually uses the resource. Default value is false.
`--lazyconnectionassociation`::
  Specifies whether a physical connection should be associated with the
  logical connection only when the physical connection is used, and
  disassociated when the transaction is completed. Such association and
  dissociation enable the reuse of physical connections. Possible values
  are as follows: +
  `false`;;
    A physical connection is associated with the logical connection even
    before the physical connection is used, and is not disassociated
    when the transaction is completed (default).
  `true`;;
    A physical connection is associated with the logical connection only
    when the physical connection is used, and disassociated when the
    transaction is completed. The `--lazyconnectionenlistment` option
    must also be set to `true`.
`--leakreclaim`::
  Specifies whether leaked connections are restored to the connection
  pool after leak connection tracing is complete. Possible values are as
  follows: +
  `false`;;
    Leaked connections are not restored to the connection pool
    (default).
  `true`;;
    Leaked connections are restored to the connection pool.
`--leaktimeout`::
  Specifies the amount of time, in seconds, for which connection leaks
  in a connection pool are to be traced. +
  If connection leak tracing is enabled, you can use the Administration
  Console to enable monitoring of the JDBC connection pool to get
  statistics on the number of connection leaks. Default value is 0,
  which disables connection leak tracing.
`--matchconnections`::
  Specifies whether a connection that is selected from the pool should
  be matched with the resource adaptor. If all connections in the pool
  are identical, matching between connections and resource adapters is
  not required. Possible values are as follows: +
  `true`;;
    A connection should be matched with the resource adaptor (default).
  `false`;;
    A connection should not be matched with the resource adaptor.
`--maxconnectionusagecount`::
  Specifies the maximum number of times that a connection can be reused. +
  When this limit is reached, the connection is closed. Default value is
  0, which specifies no limit on the number of times that a connection
  can be reused.
`--maxpoolsize`::
  The maximum number of connections that can be created to satisfy
  client requests. Default value is 32.
`--maxwait`::
  The amount of time, in milliseconds, that a caller must wait before a
  connection is created, if a connection is not available. If set to 0,
  the caller is blocked indefinitely until a resource is available or
  until an error occurs. Default value is 60000.
`--ping`::
  A pool with this attribute set to true is contacted during creation
  (or reconfiguration) to identify and warn of any erroneous values for
  its attributes. Default value is false.
`--pooling`::
  When set to false, this attribute disables connection pooling. Default
  value is true.
`--poolresize`::
  Quantity by which the pool will scale up or scale down the number of
  connections. Scale up: When the pool has no free connections, pool
  will scale up by this quantity. Scale down: All the invalid and idle
  connections are removed, sometimes resulting in removing connections
  of quantity greater than this value. The number of connections that is
  specified by `--steadypoolsize` will be ensured. Possible values are
  from 0 to `MAX_INTEGER`. Default value is 2.
`--property`::
  Optional attribute name/value pairs for configuring the pool. +
  `LazyConnectionEnlistment`;;
    Deprecated. Use the equivalent option. Default value is false.
  `LazyConnectionAssociation`;;
    Deprecated. Use the equivalent option. Default value is false.
  `AssociateWithThread`;;
    Deprecated. Use the equivalent option. Default value is false.
  `MatchConnections`;;
    Deprecated. Use the equivalent option. Default value is false.
`--raname`::
  The name of the resource adapter.
`--steadypoolsize`::
  The minimum and initial number of connections maintained in the pool.
  Default value is 8.
`--target`::
  Do not specify this option. This option is retained for compatibility
  with earlier releases. If you specify this option, a syntax error does
  not occur. Instead, the subcommand runs successfully and displays a
  warning message that the option is ignored.
`--transactionsupport`::
  Indicates the level of transaction support that this pool will have.
  Possible values are `XATransaction`, `LocalTransaction` and
  `NoTransaction`. This attribute can have a value lower than or equal
  to but not higher than the resource adapter's transaction support
  attribute. The resource adapter's transaction support attribute has an
  order of values, where `XATransaction` is the highest, and
  `NoTransaction` the lowest.
`--validateatmostonceperiod`::
  Specifies the time interval in seconds between successive requests to
  validate a connection at most once. Setting this attribute to an
  appropriate value minimizes the number of validation requests by a
  connection. Default value is 0, which means that the attribute is not
  enabled.
