Web Services Hub Properties

You can configure general, service, advanced, and custom properties for the Web Services Hub.

Use the Administrator tool to view or edit the following Web Services Hub properties:

•General properties. Configure general properties such as license and node.
•Service properties. Configure service properties such as host name and port number.
•Advanced properties. Configure advanced properties such as the level of errors written to the Web Services Hub logs.
•Custom properties. Configure custom properties that are unique to specific environments.

1. In the Administrator tool, click the Manage tab > Services and Nodes view.

2. In the Domain Navigator, select a Web Services Hub.

3. To view the properties of the service, click the Properties view.

4. To edit the properties of the service, click Edit for the category of properties you want to update.

The Edit Web Services Hub Service window displays the properties in the category.

5. Update the values of the properties.

General Properties

Select the node on which to run the Web Services Hub. You can run multiple Web Services Hub on the same node.

Disable the Web Services Hub before you assign it to another node. To edit the node assignment, select the Web Services Hub in the Navigator, click the Properties tab, and then click Edit in the Node Assignments section. Select a new node.

When you change the node assignment for a Web Services Hub, the host name for the web services running on the Web Services Hub changes. You must update the host name and port number of the Web Services Hub to match the new node. Update the following properties of the Web Services Hub:

•HubHostName
•InternalHostName

To access the Web Services Hub on a new node, you must update the client application to use the new host name. For example, you must regenerate the WSDL for the web service to update the host name in the endpoint URL. You must also regenerate the client proxy classes to update the host name.

The following table describes the general properties for the service:

Property	Description
Name	Name of the service. The name is not case sensitive and must be unique within the domain. It cannot exceed 128 characters or begin with @. It also cannot contain spaces or the following special characters: ` ~ % ^ * + = { } \ ; : ' " / ? . , < > \| ! ( ) ] [ You cannot change the name of the service after you create it.
Description	Description of the service. The description cannot exceed 765 characters.
License	License object that allows use of the service.
Node	Node on which the service runs.

Service Properties

You must restart the Web Services Hub before changes to the service properties can take effect.

The following table describes the service properties for a Web Services Hub:

Property	Description
HubHostName	Name of the machine hosting the Web Services Hub. Default is the name of the machine where the Web Services Hub is running. If you change the node on which the Web Services Hub runs, update this property to match the host name of the new node. To apply changes, restart the Web Services Hub.
HubPortNumber (http)	Port number for the Web Services Hub running on HTTP. Required if you run the Web Services Hub on HTTP. Default is 7333. To apply changes, restart the Web Services Hub.
HubPortNumber (https)	Port number for the Web Services Hub running on HTTPS. Required if you run the Web Services Hub on HTTPS. Default is 7343. To apply changes, restart the Web Services Hub.
CharacterEncoding	Character encoding for the Web Services Hub. Default is UTF-8. To apply changes, restart the Web Services Hub.
URLScheme	Indicates the security protocol that you configure for the Web Services Hub: - HTTP. Run the Web Services Hub on HTTP only. - HTTPS. Run the Web Services Hub on HTTPS only. - HTTP and HTTPS. Run the Web Services Hub in HTTP and HTTPS modes. If you run the Web Services Hub on HTTPS, you must provide information on the keystore file. To apply changes, restart the Web Services Hub.
InternalHostName	Host name on which the Web Services Hub listens for connections from the Integration Service. If you change the node assignment of the Web Services Hub, update the internal host name to match the host name of the new node. To apply changes, restart the Web Services Hub.
InternalPortNumber	Port number on which the Web Services Hub listens for connections from the Integration Service. Default is 15555. To apply changes, restart the Web Services Hub.
KeystoreFile	Path and file name of the keystore file that contains the keys and certificates required if you use the SSL security protocol with the Web Services Hub. Required if you run the Web Services Hub on HTTPS.
KeystorePass	Password for the keystore file. The value of this property must match the password you set for the keystore file.

Advanced Properties

The following table describes the advanced properties for a Web Services Hub:

Property	Description
HubLogicalAddress	URL for the third party load balancer that manages the Web Services Hub. This URL is published in the WSDL for all web services that run on a Web Services Hub managed by the load balancer.
DTMTimeout	Length of time, in seconds, that the Web Services Hub tries to connect or reconnect to the DTM to run a session. Default is 60 seconds.
SessionExpiryPeriod	Number of seconds that a session can remain idle before the session times out and the session ID becomes invalid. The Web Services Hub resets the start of the timeout period every time a client application sends a request with a valid session ID. If a request takes longer to complete than the amount of time set in the SessionExpiryPeriod property, the session can time out during the operation. To avoid timing out, set the SessionExpiryPeriod property to a higher value. The Web Services Hub returns a fault response to any request with an invalid session ID. Default is 3600 seconds. You can set the SessionExpiryPeriod between 1 and 2,592,000 seconds.
MaxISConnections	Maximum number of connections to the PowerCenter Integration Service that can be open at one time for the Web Services Hub. Default is 20.
Log Level	Configure the Log Level property to set the logging level. The following values are valid: - Fatal. Writes FATAL messages to the log. FATAL messages include nonrecoverable system failures that cause the service to shut down or become unavailable. - Error. Writes FATAL and ERROR code messages to the log. ERROR messages include connection failures, failures to save or retrieve metadata, service errors. - Warning. Writes FATAL, WARNING, and ERROR messages to the log. WARNING errors include recoverable system failures or warnings. - Info. Writes FATAL, INFO, WARNING, and ERROR messages to the log. INFO messages include system and service change messages. - Trace. Write FATAL, TRACE, INFO, WARNING, and ERROR code messages to the log. TRACE messages log user request failures. - Debug. Write FATAL, DEBUG, TRACE, INFO, WARNING, and ERROR messages to the log. DEBUG messages are user request logs. The default value is Info.
MaxConcurrentRequests	Maximum number of request processing threads allowed, which determines the maximum number of simultaneous requests that can be handled. Default is 100.
MaxQueueLength	Maximum queue length for incoming connection requests when all possible request processing threads are in use. Any request received when the queue is full is rejected. Default is 5000.
MaxStatsHistory	Number of days that Informatica keeps statistical information in the history file. Informatica keeps a history file that contains information regarding the Web Services Hub activities. The number of days you set in this property determines the number of days available for which you can display historical statistics in the Web Services Report page of the Administrator tool.
Maximum Heap Size	Amount of RAM allocated to the Java Virtual Machine (JVM) that runs the Web Services Hub. Use this property to increase the performance. Append one of the following letters to the value to specify the units: - b for bytes. - k for kilobytes. - m for megabytes. - g for gigabytes. Default is 512 megabytes.
JVM Command Line Options	Java Virtual Machine (JVM) command line options to run Java-based programs. When you configure the JVM options, you must set the Java SDK classpath, Java SDK minimum memory, and Java SDK maximum memory properties. You must set the following JVM command line option: - Dfile.encoding. File encoding. Default is UTF-8.

Use the MaxConcurrentRequests property to set the number of clients that can connect to the Web Services Hub and the MaxQueueLength property to set the number of client requests the Web Services Hub can process at one time.

You can change the parameter values based on the number of clients you expect to connect to the Web Services Hub. In a test environment, set the parameters to smaller values. In a production environment, set the parameters to larger values. If you increase the values, more clients can connect to the Web Services Hub, but the connections use more system resources.
