Published Release Notes

Empty properties are not included in snapshot

History records are smaller and more efficient, because empty properties are no longer included in the snapshot. However, as a result, the history snapshot for sections might present a distorted view of the section.

prpcUtils script fails when the connection property file location is specified

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

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

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.

Load balancing: HTTPD does not support WebSockets by default

If you use a load balancer with HTTPD (Hypertext Transfer Protocol Daemon), HTTPD does not support fully functional WebSockets and sticky sessions. By default, HTTPD does not support sticky sessions, because if it did, after a session was started, the same server would serve all requests for that session.

Default value of the threadpoolsize agent affects batch indexing

After you patch Pega Platform to version 8.5.2 or higher, the system changes the default value of the threadpoolsize agent, which controls the number of concurrent activities (threads) in the system, from 5 to 15. Batch indexing in Pega Platform™ does not require all 15 threads, so you can change the agent value to increase system performance by managing the indexing/distributed/batch/numworkers dynamic system setting.
If your deployment does not support that setting, and batch indexing does not use Queue Processors, the system uses the threadpoolsize value for batch indexing instead.

For more information, see Editing a dynamic system setting.

Naming pattern changed for file data sets

File data sets are used to import from and export data to a file repository. In case of data export, prior to version 8.6.3, the first file exported had the same file name that was provided by the user in the data set, and any subsequent file exported to the repository had a unique identifier appended to it. Starting in Pega Platform version 8.6.3, each file has a unique identifier, automatically generated based on the data flow node, thread ID, and timestamp.

Upgrade impact

If your process to consume output files expects files with a specific name, it may not be able to process the resulting files correctly.

What steps are required to update the application to be compatible with this change?

If you have configured the process before updating to Pega Platform version 8.6.3, but the exported files are no longer recognized by downstream processing logic after the upgrade, ensure that the downstream tool is configured to recognize the files by a pattern rather than the full name. For example, when referring to files exported to the repository, use the * character to indicate a pattern instead of using the full file name. For example, use Export*.csv to refer to the files.
