SAML data pages restored after passivation
Resolved in Pega Version 8.2.4
If login used SAML SSO, resuming the session after passivation resulted in missing or empty data pages when using an SAP integration with Pega Cloud. This was traced to a security change that modified the D_SAMLAssertionDataPage and D_SamlSsoLoginInfo data pages as readonly, causing them to not be passivated under these conditions. To resolve this, the data pages have been made editable so they will be restored as expected. This change also resolves any difficulty with SAML logoff activities in conjunction with SAP and Pega Cloud.

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.

Certificate match will use Subject Distinguished Name
Resolved in Pega Version 8.7
Signature verification was failing due to the system not finding the matching root certificate for the chain. The root certificate was in the trust store, but the system found a different certificate first and that other certificate (an intermediate certificate) was not considered a valid certificate for validating the whole certificate chain. This was traced to filtering on the Issuer Distinguished Name (DN) instead of the Subject DN and was due to intermediate certificates potentially having the same Issuer as a root certificate (e.g. if that root certificate was used to create the intermediate certificate). To resolve this, an update has been made to check the Subject DN instead of Issuer DN.

Local UUID cache will be updated when merge event is detected
Resolved in Pega Version 8.1.7
Cluster-related issues were seen in multiple production clusters. For some nodes in the cluster the Cluster Management screen showed all expected nodes with valid Node IDs displayed, and on other nodes the Cluster Management screen showed the node ID of itself, SERVER@localhost:5701. On an impacted node displaying the wrong ID, the Node Information landing page did not work and displayed the error "Unable to execute job on ." Multiple advanced agents running on nodes in the affected clusters, both with correct and incorrect IDs, also failed with a similar error "Unable to execute job on <node's job id>". This was traced to a merge performed after a split brain. To resolve this, the code has been updated to handle merge events: when the node UUID is changed as part of a split brain recovery, the local UUID cache will be updated when the merge event is detected.

Admin Studio will consider cluster protocol when returning listener status
Resolved in Pega Version 8.7
When using a few nodes in standalone mode for BIX extract combined with server nodes using Hazelcast, opening the admin studio pages with service discovery caused an error to be thrown. This was traced to the system writing an entry to pr_sys_statusnodes table as an embedded node whenever a BIX extract was triggered, causing those standalone nodes to be incorrectly considered by the listener landing page. This has been resolved by configuring the system to either return the local member when the cluster protocol is standalone or to return all Hazelcast members if the cluster protocol is Hazelcast.

Documentation updated for using Connect MQ with clustered queues
Resolved in Pega Version 8.5.6
After update to Pega Platform v8.6, an issue was seen with Connect MQ rules that used an alias queue. The support documentation has been revised to outline the necessary steps for updating an application to perform as expected. In the Pega-IntegrationEngine ruleset, create the following dynamic system settings and their default values: "mq/pmo" = 0 "mq/gmo" = 0 "mq/oo_request" = 1040 "mq/oo_response" = 16 For more information, dynamic system setting support articles are available.

Improved upgrade handling for tables using classes with property references
Resolved in Pega Version 8.1.7
After upgrade, some page property values were blank and exposed database columns did not contain the values. Investigation showed that the reference properties did not have context and hence column population was not able to determine their value. To resolve this, instead of doing column population for all the columns, the system will identify classes that have property references and that are being optimized as part of upgrade process and maintain a list of specific columns to update.

Handling added for using virtual network interface for Stream Services startup
Resolved in Pega Version 8.7
After update, the restart of any node failed with the error "Unable to create DSM service DATA-DECISION-SERVICE-STREAMSERVER DEFAULT". This has been resolved by adding support for allowing stream service to start on the virtual network interface in cases where it was explicitly configured via the "cluster/hazelcast/interface".
