# Configuring the IAP JMS Properties File

The `iapjms.properties` file contains all the configuration information for the `IAPJMS` process. The `iapjms.properties` file enables you to configure the following settings:

IAP JMS Properties File

Property | Description
IAPJMSConnect.InitialContextFactory | Defines the J2EE initial context factory to be used for all J2EE connections within the application.
IAPJMSConnect.InitialURL | Defines the initial context URL, if required.
IAPJMSConnect.SecurityPrinciple | Defines the username, if security is set in the InitialContextFactory. For more information, see Updating the IAP Security Principle and Credentials.
IAPJMSConnect.SecurityCredentials | Defines the password, if security is set in the InitialContextFactory. For more information, see Updating the IAP Security Principle and Credentials.
IAPJMSConnect.SecurityEncryption | Defines the encryption method used for the `IAPJMSConnect.SecurityCredentials` parameter. Valid values are:
| • | `PLAIN` - Plain text format (default)
| • | `IPE` - iPE proprietary encryption (this mechanism is used by the `swconfig` utility when writing the password)
For more information, see Updating the IAP Security Principle and Credentials.
IAPJMSConnect.TopicConnectionFactory | Defines where the JMS topic details are configured. If a topic cannot be looked up then the topic is dynamically created by the `IAPJMS` process, if possible.
IAPJMSConnect.TimeToLive | Defines the maximum time to live for the JMS messages in milliseconds. If the property is set to `0` the messages never time out. For more information, see the documentation supplied with your J2EE Application Server.
IAPJMSConnect.Priority | Defines the priority of the JMS message in the system. For more information, see the documentation supplied with your J2EE Application Server.
WQDJMSConnect.ListenerThreads | Defines the number of socket listener threads that are created when the `IAPJMS` process starts up. Note: This property is not present in the`iapjms.properties` file by default. It should only be set on instructions from TIBCO Support.
WQDJMSConnect.ConnectionPoolSize | Each work queue is required to publish its messages on the same JMS connection to ensure that messages appear in the correct order. Therefore, the `IAPJMS` process keeps a pool of JMS connection caches and ensures that all messages from each unique work queue are sent using the same connection. The connection pool is created when the `IAPJMS` process starts up. This property, therefore, defines the connection pool size, which is the maximum number of connections available for JMS publication. Each connection will always be used for all items for a single work queue. Note: This property is not present in the `iapjms.properties` file by default. It should only be set on instructions from TIBCO Support.
