Check added for equivalent table during data upgrade

Resolved in Pega Version 8.4.2

The Data Upgrade between Pega versions failed with the error "DatabaseException caused by prior exception: java.sql.SQLException: ORA-01408: such column list already indexed". This was caused by the system not considering duplicate indexes before modified indexes. Once it's identified an index has been modified, the system would try to alter it without considering that what it was altering it to might already be present. To resolve this, an update has been made so the system will not alter an index if the resulting index would be equivalent to a different one on the table.

Warning logged when hotfix rollback information fails to save

Resolved in Pega Version 8.4.2

Attempting to apply a set of hotfixes was failing. In this case, a hotfix was being installed prior to a second hotfix which contained a Rule-Obj-Class that was needed for the first hotfix. Hotfixes need to be installed in a particular order based on their dependencies. For a given DL file, the installer respects the order specified at DL packaging time in the INSTALLORDER.PEGA file. The install order specified in the DL file is roughly ordered in a manner so that the first hotfix is the parent (the specific hotfix requested by the user at DL packaging time) followed by its dependencies in no particular order. The result was that dependencies of dependencies were not installed in the correct order relative to each other, causing hotfix installation to occasionally fail during the saving of hotfix rollback information. To address this failure, the exception handling has been modified to only provide a warning in the log should hotfix rollback saving fail and not cause the entire hotfix installation to fail.

SQL 'where' clause updated to handle Oracle limits

Resolved in Pega Version 8.4.2

Due to Oracle only allowing up to 1,000 IN list values in a SQL statement, a query exceeding that limit fails. To resolve this, the 'where' clause of the query has been updated to better handle this limit. The format is: WHERE col_name IN (val1, val2,……,val999) OR col_name IN (val1000, val1001,…)

ProductInfoReader updated to fetch only most recent version information

Resolved in Pega Version 8.4.2

After upgrade, running Hfix scanner on Pega Marketing 8.2 displayed missed critical Hfixes for Pega Marketing 8.1. This has been resolved by modifying ProductInfoReader.runQuery to fetch only latest version of DAPF instances during a scan. In addition, the 50 result limit on executeRDB has been lifted to accommodate sites with more than 50+ Data-Admin-Product-Frameworks.

TableRenameUtil hashing improved

Resolved in Pega Version 8.4.2

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.

View/Modify Database Schema Wizard updated

Resolved in Pega Version 8.4.2

Security improvements have been made to the View/Modify Database Schema Wizard.

Retry logic added for downloading upgraded rules

Resolved in Pega Version 8.1.9

A Rules upgrade failed while downloading applications from the maintenance server due to an SFTP server connection failure. This has been resolved by adding logic to retry if the first connection attempt fails.

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.
