INC-130304 · Issue 567924

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.

INC-133202 · Issue 574701

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.

SR-D84364 · Issue 551402

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.

SR-D32972 · Issue 513488

HTML entity handling added to URLObfuscation

Resolved in Pega Version 8.2.5

When URLObfuscation was enabled through the configuration settings, clicking on Operator -> Profile page generated an ArrayIndexOutOfBoundException. When obfuscation is used the decrypted string is parsed and the request map is populated, but HTML entities were not considered during this process. To resolve this, handling has been added for HTML entities and characters during obfuscation. Please note: URL Obfuscation is a legacy feature with many known limitations and it is no longer recommended that these settings be used.

SR-D37894 · Issue 505975

Query parameters will be cleared after redirection from authentication

Resolved in Pega Version 8.2.5

When using the /PRAuth Servlet, running a snapstart URL generated from a secondary application correctly executed SAML Authentication and Pega processing, but a second URL generated with different parameters ran with the parameters from the first request. The third and subsequent requests processed as expected with the parameters sent in with the request. Investigation showed that the previous parameters were picked due to the query string parameters not being cleared after redirection, and this issue has been resolved by updating the system so it will clear the parameters after issuing a redirect from the authentication policy engine.

SR-D38318 · Issue 515960

Data pages explicitly cleared after QP use

Resolved in Pega Version 8.2.5

The Util Node was showing as Offline in the Search Landing Page, and when Jobs were submitted for execution from other Nodes the message "Detected active run with unreachable nodes" was logged. The util node, configured as a backgroundprocessing node, was running QPs, the queue size for custom QPs is 500 messages /queue items per minute, but investigation showed the requestor level and thread level data pages corresponding to the QP activities were not being cleared after use. This led to high heap memory issues that made the node unreachable, and has been resolved by adding code to explicitly remove the data pages when processing has finished.

SR-D46536 · Issue 515793

Custom agent next run time will be rescheduled if the run failed

Resolved in Pega Version 8.2.5

If a customized agent that was set to run every day encountered an exception and failed to run, restarting the agent did not update it to the next run time, it still returned the passed trigger time as its next execution time. This has been resolved with an update that will reschedule the run if the next run time is in the past.

SR-D46681 · Issue 514433

SnapStart supports SAML2 Authentication

Resolved in Pega Version 8.2.5

When using an HTTP Post to SnapStart into Pega using PRCustom style or PRAuth style SAML authentication, the login was looping back to the login request. Investigation showed that the Pega ACS was posting data properly back to the RelayState URL, however the login activity was not getting the SAMLResponse and simply sent a SAML Login Request again. This has been fixed by updating reqContextURI in case of SAML2 Authentication service so pyActivity=value will be passed.
