WSDL generation error prevents invocation of SOAP services

Valid from Pega Version 8.4.2

Status

A Known Issue was introduced in the 8.4.2 Pega Platform patch release, which impacts both upgrades and new installations of that version.

Description

Due to changes introduced in the SOAP functionality for the case-mismatch error in SR-D98509/INC-119725, the WSDL is being generated for SOAP services with an incorrectly-capitalized element, which prevents the service from being invoked.  The element should be “name” instead of “Name”.

Workaround

Clients must perform the following workaround after they define a new SOAP connector in Pega Platform:

  1. To download the WSDL from Pega Platform:
    1. After using the SOAP Wizard (Dev Studio > Configure > Integration > Services > Service Wizard) the WSDL URL is shown at the bottom right of the Dev Studio screen.
    2. Click the URL to display the XML.
    3. Save the WSDL file to your local system.
  2. In the text editor of your choice, modify "Name" to "name" in every <element “name” = … > tag in the WDSL.
  3. Save your changes to the local file.
  4. To reload the WSDL into Pega Platform:
    1. In Dev Studio, open the Configure menu.
    2. Select Integration > Connectors > Create SOAP Integration.
    3. In the New SOAP integration wizard, select Upload WSDL from File.
    4. Complete the upload using the wizard prompts.

This is a design-time issue, not a run-time issue; therefore, clients only have to perform this workaround process once. Existing SOAP services should not be impacted; however, if clients modify an existing SOAP service definition by re-running the wizard, clients must reapply the workaround for Pega Platform to recognize the SOAP definition changes.  

Resolution

This issue will be addressed in the Pega Platform Patch Release 8.4.3.  Clients who upgrade to that version or later should not see this issue.

Schema not found error when importing a Rule-Admin-Product file

Valid from Pega Version 7.1.8

If you import a Rule-Admin-Product file (RAP) file that includes a schema that has a view, grammar parsing changes can mean that the Pega 7 Platform is unable to find the schema.

To enable the Pega 7 Platform to find the schema:

  1. Review the error message that indicates that the schema was not found and identify the following items:
    • The name of the schema that is causing the error
    • The table name in the format: wrong_schema_name.table_name...
    • The DDL that the Pega 7 Platform is trying to apply
  2. Use the table name to identify the correct schema name in your system. This schema is usually your data schema, but might also be an external database.
  3. Download the DDL.
  4. Correct the schema name and save the DDL.
  5. Manually apply the DDL.

High number of busy waits when using Oracle SecureFiles

Valid from Pega Version 7.2.1

You might experience a high number of buffer busy waits when using Oracle SecureFiles for BLOB storage. An Oracle buffer busy wait occurs when a session cannot access a database block in the buffer cache, because another session is either reading the block into the buffer or changing the buffer. As a best practice, use Oracle 11.2.0.4 or later, because earlier versions have more problems with SecureFiles. In addition, to minimize the number of busy waits, set the hidden Oracle parameter _securefiles_concurrency_estimate to 50, and partition the table by using a composite range hash partition that is based on the pxCreateDateTime and pzInskey columns.

For more information, see Troubleshooting: High number of busy waits when using Oracle SecureFiles.

Extract marker file not created at startup

Valid from Pega Version 7.2.1

The extract marker file (PegaRULES_Extract_Marker.txt) is not created at startup, because the rule utility libraries no longer need it. If you used to use the extract marker file to clear the static content file-based cache, to look up lists, or to control starting activities with web nodes, you can delete the contents of the PegaRULES temporary directory instead.

System starts slowly after upgrade or update on IBM DB2 for z/OS

Valid from Pega Version 7.2.2

Additional tables are added to upgraded and updated systems. If your system starts up very slowly after an upgrade or update, the database statistics on these new tables might not have generated correctly. To correct this issue and improve performance, your database administrator needs to manually rebuild the statistics for all tables in the rules schema.

Clustering equal to none might cause errors

Valid from Pega Version 7.2.2

Some Pega 7 Platform features might not work when theidentification/cluster/protocolsetting in the prconfig.xml file is set to none. Some features that might not work are remote tracing and management actions on the node from the Requestor Management and Agent Management landing pages. Setting the clustering protocol to none is not recommended and will not be supported in a future Pega 7 Platform release.

Disregard this startup error for Oracle Weblogic deployments

Valid from Pega Version 7.2.2

If you install, upgrade, or update your Oracle Weblogic application server to Pega 7.2.2, disregard the error stack that begins with text similar to the following:

ERROR - WebLogic Server 12.1.3.0.0 Wed May 21 18:53:34 PDT 2014 1604337 Oracle WebLogic Server Module Dependencies 12.1 Tue Mar 11 15:35:15 MDT 2014 WebLogic Jersey Server Integration 3.0 Fri Feb 21 10:55:11 UTC 2014 must use JDK 1.8+ with WebSocket
2016-11-07 06:13:01,690 [ WIN-L3EEURCNCP1] [ STANDARD] (pr.DefaultAsyncSupportResolver) ERROR - Real error: Unable to configure jsr356 at that stage. ServerContainer is null

This message appears because the Pega 7.2.2 real-time notification feature initially tries to use WebSocket and then falls back to long polling. The Pega 7 Platform does not support WebSocket for Oracle Weblogic servers, and instead uses long polling for real-time notifications.

Disregard this Java script console message

Valid from Pega Version 7.2.2

Pega 7.2.2 introduced real-time notifications by using Comet technologies such as WebSocket and long polling. WebSocket provides the best results, but both WebSocket and non-blocking long polling must be supported by your application server. If your application server does not support WebSocket, you might see a JavaScript error that begins with text that is similar to the following text:

WebSocket connection to 'ws://vnbamdevapp01:8080/prweb/PRPushServlet/... Error during WebSocket handshake: Unexpected response code: 501_getWebSocket @ pzpega_ui_messaging_1802554968!!.js:1195 pzpega_ui_messaging_1802554968!!.js:3265 Websocket closed, reason: Connection was closed abnormally (that is, with no close frame being sent). - wasClean: falselog @ pzpega_ui_messaging_1802554968!!.js:3265 pzpega_ui_messaging_1802554968!!.js:3265 Websocket failed on first connection attempt. Downgrading to long-polling and resending

You can disregard this message.

However, to take advantage of the improvements to real-time notifications, enable support for WebSocket:

  • For IBM WebSphere Application Server Liberty Core, see your deployment guide for instructions on configuring the application server.
  • For Red Hat JBoss, see your deployment guide for instructions on enabling WebSocket support.
  • For Apache Tomcat application servers, consider upgrading to Apache Tomcat 7.0.53 or later which supports WebSocket.

prpcUtils script fails when the connection property file location is specified

Valid from Pega Version 7.2.2

If you run the prpcUtils command-line script and pass the --connPropFile argument to specify the location of the connection properties file, the script fails with the following error:

Problem: failed to create task or type ac:/antcontrib.org:for

This error does not appear if you do not pass the --connPropFile argument, or if you use the prpcServiceUtils scripts.

As a workaround, edit the prpcUtilsWrapper.xml file:

  1. Open <distribution>\scripts\utils\prpcUtilsWrapper.xml.
  2. Locate the following line:

    <taskdef resource="net/sf/antcontrib/antcontrib.properties" uri="ac:/antcontrib.org">

  3. Replace that line with the following line.

    <taskdef resource="net/sf/antcontrib/antlib.xml" uri="ac:/antcontrib.org">

  4. Save and close the file.

Data schema requires update after multitenant upgrade

Valid from Pega Version 7.2.2

After an out-of-place, multitenant upgrade to Pega 7.2.2 from Pega 7.2 or later, the PR_DATA_TAG_RELEVANTRECORD table that is in the existing data schema is not present in the new rules schema. The table must be present in the rules schema for the upgrade to the rules schema to work. Copy the PR_DATA_TAG_RELEVANTRECORD table from the existing data schema to the new rules schema, and then upgrade the new rules schema. The PR_DATA_TAG_RELEVANTRECORD table is not required to be in the rules schema. After the rules schema upgrade is finished, drop the copy of the table that is in the new rules schema before you upgrade the data schema.
