name

none 

Specifies the name of the connection pool. A connector-resource element’s pool-name attribute refers to this name.

resource-adapter-name

none 

Specifies the name attribute of the deployed connector-module. If no name is specified during deployment, the name of the .rar file is used. If the resource adapter is embedded in an application, then it is app_name#rar_name .

connection-definition-name

none 

Specifies a unique name, identifying a resource adapter’s connection-definition element in the ra.xml file. This is usually the connectionfactory-interface of the connection-definition element.

steady-pool-size

8

(optional) Specifies the initial and minimum number of connections maintained in the pool. 

max-pool-size

32

(optional) Specifies the maximum number of connections that can be created to satisfy client requests. 

max-wait-time-in-millis

60000

(optional) Specifies the amount of time, in milliseconds, that the caller is willing to wait for a connection. If 0, the caller is blocked indefinitely until a resource is available or an error occurs.

pool-resize-quantity

2

(optional) Specifies the number of connections to be destroyed if the existing number of connections is above the steady-pool-size (subject to the max-pool-size limit).

This is enforced periodically at the idle-time-out-in-seconds interval. An idle connection is one that has not been used for a period of idle-time-out-in-seconds .

idle-timeout-in-seconds

300

(optional) Specifies the maximum time that a connection can remain idle in the pool. After this amount of time, the pool can close this connection. 

fail-all-connections

false

(optional) If true, closes all connections in the pool if a single validation check fails.

transaction-support

none 

(optional) Specifies the transaction support for this connection pool. Overrides the transaction support defined in the resource adapter in a downward compatible way: supports a transaction level lower than or equal to the resource adapter’s, but not higher. Allowed values in descending order are: 

• XATransaction - Supports distributed transactions.

• LocalTransaction - Supports local transactions only.

• NoTransaction - No transaction support.
