JavaMail API upgrade has potential SMTP configuration error

Valid from Pega Version 7.1.8

The JavaMail API has been upgraded from 1.4.1 to 1.5.2 in this release. This improvement provides greater compatibility and secure connectivity with leading industry email servers.

During the upgrade process, there is a known issue for some configurations of email servers, including Microsoft Exchange Server, that requires the use of an additional setting. After upgrading to this release, if you experience authentication failures when attempting to send email or test SMTP connectivity, do one of the following:

  • Recommended: Review the Microsoft Exchange email server settings to ensure proper configuration for SMTP authentication. In some cases, the use of port 587 instead of the traditional default SMTP port 25 has been shown to address this issue.
  • Create the following Dynamic System Setting with the value "true," and then restart email listeners:

Owning Ruleset: Pega-IntegrationEngine

Setting Purpose: javamail/NoAuthMechanismsRetry

After any email server configuration or upgrade, it is recommended that email listeners are re-tested without using this Dynamic System Setting.

See About Email Account data instances for information on configuring email account records.

Creating data page unit tests in Internet Explorer 8

Valid from Pega Version 7.1.8

When creating data page unit tests, selecting a parent property does not automatically select the child properties when using Internet Explorer 8.

Page and page list properties to be included in a data page unit test are selected on the Create test screen by selecting a check box next to the property name. Normally, selecting the check box of a parent property automatically selects all subsequent child properties as well. When using Internet Explorer 8, child properties are not automatically selected when the parent property's check box is selected.

The solution requires selecting all of the desired child properties individually. Select the check box next to each child property to include it in the data page unit test.

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.

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.

Push notifications and Oracle WebLogic Server 10.3.6

Valid from Pega Version 7.2.2

Pega® Platform push notifications can use WebSockets and long polling. However, for WebLogic Server 10.3.6, the push notifications feature does not work. To disable the feature, contact Pegasystems Global Customer Support.
