Enhancements for upgrading in multi-tenant environment
Resolved in Pega Version 8.1.9
Some muti-tenant installations use the same applications or rule instances with the same pzInsKeys for different tenants. This can cause upgrades to time out due to the system fetching all pzInsKeys (which will have duplicates) and working with them in a default batch size of 500 each over 4 threads. This led to the same keys potentially being allocated and processed in different threads, resulting in duplicate processing and timeouts. This has been resolved by updating the select query to fetch the tentantid and pzInskeys in the MT system to avoid duplicate work in multiple threads. In addition, running Generate Declarative indexes fetches the pzinskeys and generates indexes for each record, but before generating, the existing index for the record is deleted and then inserted. Because the delete query to generate the index was not tenant aware, all of the records for the key were deleted for the tenants for that key, but the new index was created only in one tenant. This has been resolved by enhancing the DELETE query to be tenant aware, which will avoid deleting the indexes for all the tenants given an index key.

Resolved buffer overflow for Migration loadDatabase
Resolved in Pega Version 8.1.9
A Rules upgrade failed in the Migration step at loadDatabase stage, involving the move of all the table records from old schema to new schema. This was traced to the inability of Migration to load blob of sizes more than 100 MB, and has been resolved by updating Migration to use byte[] to read the blob content with the help of metadata that contains blob length.

TableRenameUtil hashing improved
Resolved in Pega Version 8.1.9
During index name generation, the algorithm that was responsible for index name uniqueness was sometimes insufficient and cerated a loop condition. This has been resolved by using a stronger hash algorithm and refactoring the code that could result in a loop.

Check for circular references added to SearchInventoryImpl to prevent recursive call
Resolved in Pega Version 8.1.9
An out of memory error was traced to SearchInventoryImpl infinitely recursing over a clipboard property, where the child property referenced a parent property and resulted in an endless loop. This has been resolved with the addition of a depth check to ensure that the search does not recurse infinitely.

Added check for naming conflicts when upgrading Oracle
Resolved in Pega Version 7.2
When attempting to upgrade a single schema on Oracle database, running the generateddl script failed with a NullPointerException. This was caused by database tables which had a column name called 'SYS_ID' as part of the primary key. Since Oracle uses system-generated names beginning with "SYS_" for implicitly generated schema objects and subobjects, Oracle discourages the use of this prefix in the names explicitly provided to the schema objects and subobjects in order to avoid possible conflicts in name resolution. To resolve this, a tester has been added to the system to check for this naming use and issue a warning.

Documentation added on adding Tomcat-on-Oracle Rules resource
Resolved in Pega Version 7.2
The Tomcat-on-Oracle installation guides for Pega ML7 and ML8 did not contain instructions for adding a for jdbc/AdminPegaRULES. As such if the installer prepared a two-user (Base + Admin) setup in the database and allocated the Base user to jdbc/PegaRULES, the Pega platform was unable to run DDL to create new tables for new work types and new data types, as the installer has not configured the additional datasource to use the Admin user. The documentation has been updated to add the necessary step between Steps 1 and 2 of the "Create a JDBC Datasource" chapter (page 41 from the ML7 installation guide).

Documentation updated for command-line BIX extractions

The documentation for "Using a stand-alone command-line BIX extract process" has been updated to refer to the BIX 7.1 User's Guide regarding configuring the necessary database connection properties set (prbootstrap, prconfig, etc.).

Documentation updated to reflect change to read-only getProperty pages
Resolved in Pega Version 7.2
In recent versions of the system, getProperty() was modified to support the creation of a property on a read-only page. However, even though the property has been created, it is not possible to set its value. This was not clearly indicated in the documentation, and read-only exceptions were being generated when putString() or setValue() attempted to give a value for the property on a read-only page. The documentation has been updated to clarify this use case.

JDBC connection URL documentation updated for JBOSS installation
Resolved in Pega Version 7.2
An error was found in the JBOSS installation document: the JDBC connection URL defined inside the standalone-full.xml should not have forward slash (/) before the database name, i.e. the format below is incorrect: jdbc:oracle:thin:@//localhost:1521/dbName Instead, the forward slash before data name should be changed to a colon (:), for example: jdbc:oracle:thin:@//localhost:1521:dbName This documentation issue has been resolved by adding a section clarifying the necessary connection information and the method for creating a connection string, along with updating all connection-url steps to either include this information or a pointer to the new section.
