Installation instructions

Before you begin, ensure that the following service has been applied to the application server for the Access Gateway and Service Platform:

Note: In this section, WAS_ROOT refers to the WebSphere home directory, for example /opt/IBM/WebSphere/AppServer.

To apply the fix pack, complete the following steps:

  1. Verify that the WebSphere Application Server (WAS) version is 6.1.0.11, and that the appropriate iFix or iFixes have been applied.
  2. Verify that the WebSphere Application Server Enterprise Service Bus (ESB) version is 6.0.2.2, and that the appropriate iFix or iFixes have been applied.
  3. If you have an earlier TWSS fix pack that was installed using the Update Installer, uninstall it. The TWSS Update Installer fix packs are cumulative.
  4. Download the Websphere Update Installer version 6.1.0.11 on both the Access Gateway application servers and the Service Platform application servers. You will use this version of the update installer for both the Access Gateway which is based on WAS 6.0 and the Service Platform which is based on WAS 6.1
  5. Download the IMS UPDI Plugins package 6.2.0.0-WS-WAS-IMS-UPDIPlugins.pak into the WAS_ROOT/updateInstaller/maintenance directory on both the Access Gateway application servers and the Service Platform application servers.
  6. Download the TWSS Update Installer package 6.2.0-WS-WAS-TWSS-AG-IF000002.pak into the WAS_ROOT/updateInstaller/maintenance directory on the Access Gateway servers.
  7. Download the TWSS Update Installer package 6.2.0-WS-WAS-TWSS-SP-IF000002.pak into the WAS_ROOT/updateInstaller/maintenance directory on the Service Platform servers.
  8. Download the TWSS Update Installer package 6.2.0-WS-WAS-TWSS-Services-IF000002.pak into the WAS_ROOT/updateInstaller/maintenance directory on the Service Platform servers.
  9. Start the Update Installer as described in the WebSphere documentation, and select the TWSS fix pack(s) to be installed.
    The UPDI Plugins package should be installed first to each server.
    The 6.2.0-WS-WAS-TWSS-AG-IF000002.pak contains updates to the Access Gateway.
    The 6.2.0-WS-WAS-TWSS-SP-IF000002.pak contains updates to the Service Platform and should be installed before the services.
    The 6.2.0-WS-WAS-TWSS-Services-IF000002.pak contains updates to the TWSS Services.

    The Update Installer updates the WAS_ROOT/installableApps/TWSS-Base and WAS_ROOT/installableApps/TWSS-Services directory contents, but does not deploy the updates onto the application server.

  10. Update the component EARs that are deployed on the application server:
    1. Start WebSphere Application Server where the component is installed.
    2. Open the Integrated Solutions Console and log in.
    3. Click Applications > Enterprise Applications and select the appropriate Application EAR.
    4. Click Uninstall.
    5. Follow the instructions in the information center to install the new EARs included in the fix pack. Refer to the following instructions: http://publib.boulder.ibm.com/infocenter/wtelecom/v6r2m0/topic/com.ibm.twss.install.doc/intro_c.html
  11. Review iFix contents for updated database initialization (.ddl) files or policy initialization script (.py) files, and use them to initialize the database or policies according to the instructions in the InfoCenter.

 

Configuration instructions

The configuration for TWSS is the same as that described in the InfoCenter, except as specified in either the TWSS 6.2.0 Readme (WebSphereProductsForTelecomReadme.html) or this Readme.

Attachment Limit Configuration

This iFix defines a default SOAP attachment size limit of 1 MB, requiring that the size of any one attachment or the combination of all attachment parts passed on a Web service request not exceed this limit. This iFix also adds the ability to override the default attachment size limit through the use of name space bindings. There are two name space binding values that can be defined to set the size limit for attachments: one to set the individual size limit for attachment parts and the second to set the overall limit for all attachments.

To change the default SOAP attachment size limit, complete the following steps on the deployment manager and synchronize the changes with all nodes:

  1. Log in to the Integrated Solutions Console.
  2. In the navigation panel, click Environment > Naming > Name Space Bindings.
  3. Select cell_name for the Scope, and click Apply.
  4. To change the default maximum size of an attachment part that can be attached to an inbound message, create a name space binding for the SOAP attachment part maximum size:
    1. Click New.
    2. Click String for the binding type, and click Next.
    3. Type SOAP_attachment_part_max_size for the Binding Identifier.
    4. Type sca/attachments/MaxSizeAttachmentPart for the Name in Name Space.
    5. Type the maximum allowed size of an attachment part for a given message. This is an integer number measured in MBytes (when followed by 'M' or 'm'), or KBytes (when followed by 'K' or 'k'), or bytes (when followed by 'B' or 'b'). The default value used is '1M'.
    6. Click Finish, and click Save to save changes to the master configuration.
  5. To change the default maximum size of all attachment parts that can be attached to an inbound message, create a name space binding for the SOAP attachment maximum size:
    1. Click New.
    2. Click String for the binding type, and click Next.
    3. Type SOAP_attachment_max_size for the Binding Identifier.
    4. Type sca/attachments/MaxSizeAttachments for the Name in Name Space.
    5. Type the maximum allowed size of all attachment parts for a given message. This is an integer number measured in MBytes (when followed by 'M' or 'm'), or KBytes (when followed by 'K' or 'k'), or bytes (when followed by 'B' or 'b'). The default value used is '1M'.
    6. Click Finish, and click Save to save changes to the master configuration.

system_type configuration

In either the SMS or WAP applications for SMPP, use the TWSS Administration Console to locate the Network Mapper configuration page. That page contains an additional configuration setting for the value used in the system_type field of the SMPP Bind Transceiver operation.

reorgchk to optimize DB2 performance

DB2 relies upon calculated values for optimal performance. The database catalog statistics and the physical organization of the data in the tables are used to provide optimal database performance. Catalog statistics should be recomputed periodically as the data in the tables changes. This need is greatest after periods of heavy data modifications (inserts, updates, and deletes) such as during initial population or periodic purge activities. These calculations are CPU intensive and block access to the database while they run. We recommend this maintenance be performed during an appropriate service window.

The DB2 reorgchk command is the simplest way to count and record the statistical details about tables, indexes and columns. There are other more tightly focussed techniques that may provide improved results. If you experience poor database perforamnce after completing this command please consult the database administrator and inquire about using other techniques to improve the database performance.

db2 reorgchk update statistics on table all

No J2C activation specification for the MM7 Resource Adapter

When installing the MM7Connector.rar (MM7 Resource Adapter), there is no J2C activation specification associated with that adapter. Therefore, when you use the procedure titled "Installing the JCA adapter for SMPP and MM7-based Web service implementations" in the InfoCenter (http://publib.boulder.ibm.com/infocenter/wtelecom/v6r2m0/topic/com.ibm.twss.install.doc/jca_adapter_t.html), you should skip step 4 when deploying Parlay X Multimedia Messaging over MM7.

Disabling PMI improves performance

The TWSS 6.2.0.0 product readme recommends turning off PMI (Performance Monitoring Interface) in order to avoid a performance problem. There is a more specific method of disabling the specific PMI metrics that cause the performance problem, which allows PMI to be generally used.

  1. In the WAS Administration Console, on the left side, click Monitoring and Tuning > Performance Monitoring Infrastructure (PMI).
  2. Select the correct application server instance. This should be done for each application server instance when in a cluster.
  3. Ensure that Enable PMI is checked.
  4. Click Custom.
  5. On the left side of the customization area, select Web Applications.
  6. Select URIConcurrentRequests, URIServiceTime, and URIRequestCount.
  7. Select Disable.
  8. Save the changes and restart the server.

Performance improvement for DNS lookups

If you experience very slow response from the TWSS Administration Console or Parlay Administration Console, particularly on AIX, this can be due to poor or unpredictible response times from the DNS server. The Java JVM provides a system property com.ibm.cacheLocalHost that can be set to true. This will improve lookups of the localhost IP address. This Java JVM system property should be set in the Process Definition for the Deployment Manager and all Application Server instances.

Uninstall instructions

The TWSS product InstallShield installers provide an uninstaller. However, the uninstaller does not uninstall Update Installer .pak files. To uninstall TWSS components, uninstall any Update Installer packages first. Then use the product InstallShield uninstallers.
