Additional upgrade scripts for new columns

Valid from Pega Version 7.1.4

In Version 6.2, additional columns (Major, Minor, and Patch) containing ruleset Version information were added to 15 tables in the PRPC database. When upgrading from a pre-Pega 7 release, scripts must be manually run after the upgrade to populate these columns.

These scripts are located in the Resource Kit, under Additional Upgrade Scripts.

  • If upgrading to a single schema, run both scripts.
  • If upgrading to a split schema, run the _data script against the data schema and run the _rules script against the rules schema.
  Depending upon your database type (platform) and the size of your database, these scripts may require significant time and system resources to run.

Choose the scripts for your database type:

  • db2zos_rulesetversion_columns_data.sql
  • db2zos_rulesetversion_columns_rules.sql

 

  • mssql_rulesetversion_columns_data.sql
  • mssql_rulesetversion_columns_rules.sql

 

  • oracle_rulesetversion_columns_data.sql
  • oracle_rulesetversion_columns_rules.sql

 

  • postgres_rulesetversion_columns_data.sql
  • postgres_rulesetversion_columns_rules.sql

 

  • udb_rulesetversion_columns_data.sql
  • udb_rulesetversion_columns_rules.sql

Required Oracle optimization parameter

Valid from Pega Version 7.1.3

To optimize performance, set the Oracle parameter optimizer_index_cost_adj to a value between 20 and 25. If this value is not set, the system can run exceedingly slowly, potentially blocking users from login.

Split schema upgrade instructions missing properties

Valid from Pega Version 7.1.3

If you upgraded from 5.x, 6.x, or 7.x using the instructions in previous versions of the upgrade guide, you may have neglected to set the properties below in your migrateSystem.properties file when you migrated your upgraded schema to the source system:

 

pega.rules.objects.generate=true

pega.rules.objects.apply=true

 

If these properties were not set during an upgrade that splits the schema, your environment does not have the indexes, triggers, and primary keys on the rules tables.

 

To check for this issue, see if the pr4_base and pr4_rule rules tables in your existing rules schema are missing primary keys. If they are, use the SQL scripts in the ResourceKit\MigrationRecoveryScripts directory of the release to cleanup duplicate rules that were created due to this issue. Follow the steps below to run the scripts.

To run the scripts on Microsoft SQL, Oracle, or PostgreSLQ

  1. Take down any app servers using the affected schema.
  2. Backup your database.
  3. Replace all instances of @RULES_SCHEMA in <database>_cleanDups.sql with the name of the schema that contains the pr4_base table.
  4. Run the <database>_cleanDups.sql script on the database with vendor tools (sqlPlus, SQL Server Management Studio, etc).
  5. Replace all instances of @RULES_SCHEMA in <database>_fix_vw_table.sql with the name of the schema that contains the pr4_base table.
  6. Run the <database>_fix_vw_table.sql script on the database with vendor tools (sqlPlus, SQL Server Management Studio, etc).
  7. Generate and apply the ddl using the command line generateDDL command. Check the installation guide for your database or the upgrade guide for details about how to use the generateDDL command line script.
  8. Rebuild the indexes for the tables in your rules schema using vendor tools. This is necessary so that your system runs at an optimum speed.
  9. Optionally upgrade to the latest release, at this point your database is ready to be upgraded or used depending on your needs.

      

To run the scripts on DB2 for LUW or z/OS

  1. Take down any app servers using the affected schema.
  2. Backup your database.
  3. Run the <database>_cleanDups.sql script on the database with vendor tools (UDB CLP, Data Studio, etc) to create the CLEANSE_RULES_DUPS stored procedure.
  4. Run the query Call CLEANSE_RULES_DUPS(‘<rulesSchema>’); where <rulesSchema> is the name of schema that contains the pr4_base table.
  5. After the previous step is complete drop the CLEANSE_RULES_DUPS procedure.
  6. Replace all instances of @RULES_SCHEMA in <database>_fix_vw_table.sql with the name of the schema that contains the pr4_base table.
  7. Run the <database>_fix_vw_table.sql script on the database with vendor tools (UDB CLP, Data Studio, etc).
  8. Generate and apply the ddl using the command line generateDDL command. Check the installation guide for your database or the upgrade guide for details about how to use the generateDDL command line script.
  9. Rebuild the indexes for the tables in your rules schema using vendor tools. This is necessary so that your system runs at an optimum speed.
  10. Optionally upgrade to the latest release. At this point your database is ready to be upgraded or used depending on your needs.

Synchronized database and application server settings

Valid from Pega Version 7.1.3

Configure your database and application server to use the same time zone and character encoding to avoid conflicts.

Column Populator utility documentation out of date for prior versions

Valid from Pega Version 7.2

The documentation for using the Column Populator utility to populate newly exposed database columns is out of date for Pega 7 Platform versions prior to 7.2. For all Pega 7 versions, refer to the Pega 7.2 help documentation for instructions about how to use this utility.

End of support for Microsoft Internet Explorer 9 and Internet Explorer 10

Valid from Pega Version 7.2

In accordance with Microsoft’s announcement to discontinue support for Internet Explorer 9 and Internet Explorer 10 in January 2016, Pega 7.2 will be the last version of the Pega 7 Platform to support Internet Explorer 9 and Internet Explorer 10.  

For Pega 7.2.1, you must upgrade to Microsoft Internet Explorer 11 or later, or use Google Chrome, Apple Safari, or Mozilla Firefox.

For more information about browser support, see the Platform Support Guide or contact Pegasystems Global Customer Support.

Child case queries performance can be slow

Valid from Pega Version 7.2

Some customers have reported that performance is slow when they execute queries on child cases. This issue is often indicated by PEGA0005 (query time exceeded limit) alerts that can be correlated to these queries in the logs. To resolve the issue, add a database index to each of your work tables by using a multicolumn index on the pxCoverInsKey, pxObjClass, and pyStatusWork columns.

See Performance improvements for child case queries.

Verify ML Readiness error: Upgrades from Pega 7.1.0 through 7.1.8 do not replace nonversioned rules

Valid from Pega Version 7.2

Upgrading from any Pega 7 Platform version between Pega 7.1 and Pega 7.1.8 to Pega 7.2 does not automatically replace nonversioned rules. If you revalidated and saved a Pega 7.1.x rule after the timestamp on the Pega 7.2 version of the rule, upgrading to Pega 7.2 does not overwrite the saved rule. You might see either of the following behaviors:

  • The upgrade fails with the following error message:
    Verify ML Readiness
  • The upgrade succeeds, but you might be unable to open changed rule forms.

If the upgrade fails, see the Pega 7 Platform Upgrade Guide to force the upgrade.

This known issue does not affect Pega 7.1.9. After the upgrade has finished, apply Hotfix 27288. For information about obtaining and applying hotfixes, see Hotfix Manager.

Unused agents run in background

Valid from Pega Version 7.2

The Update PegaRULES database table statistics agent and the Collect PegaRULES database blob size statistics agent have been added to support future development. These agents run in the background, but they do not do anything. You can, but do not need to, disable them from the Edit Agent Schedule landing page.

For more information, see Agent Schedule form - Completing the Schedule tab.
