Data schema requires update after multitenant upgrade
Valid from Pega Version 7.2.2
After an out-of-place, multitenant upgrade to Pega 7.2.2 from Pega 7.2 or later, the PR_DATA_TAG_RELEVANTRECORD table that is in the existing data schema is not present in the new rules schema. The table must be present in the rules schema for the upgrade to the rules schema to work. Copy the PR_DATA_TAG_RELEVANTRECORD table from the existing data schema to the new rules schema, and then upgrade the new rules schema. The PR_DATA_TAG_RELEVANTRECORD table is not required to be in the rules schema. After the rules schema upgrade is finished, drop the copy of the table that is in the new rules schema before you upgrade the data schema.
Push notifications and Oracle WebLogic Server 10.3.6
Valid from Pega Version 7.2.2
Pega® Platform push notifications can use WebSockets and long polling. However, for WebLogic Server 10.3.6, the push notifications feature does not work. To disable the feature, contact Pegasystems Global Customer Support.
Load balancing: HTTPD does not support WebSockets by default
Valid from Pega Version 7.2.2
If you use a load balancer with HTTPD (Hypertext Transfer Protocol Daemon), HTTPD does not support fully functional WebSockets and sticky sessions. By default, HTTPD does not support sticky sessions, because if it did, after a session was started, the same server would serve all requests for that session.
WebSphere log error with Java 8 for Enterprise JavaBeans
Valid from Pega Version 7.1.8
For environments that are deployed by using Java 8 on IBM WebSphere Application Server version 8.5.5.9 through the last 8.5.5.x fix pack, the log might report that a class was not found when the application server attempts to start Enterprise JavaBeans. If Java EE functionality is not needed, no further action is required. However, to use Enterprise JavaBeans, see WebSphere log error with Java 8 for Enterprise JavaBeans.
Precision of Oracle Timestamp property when using RDB-Save
Valid from Pega Version 7.1.8
DateTime properties that are mapped to an Oracle Timestamp column will experience a loss of precision when they are saved using the RDB-Save method. When you use RDB-Save for an Oracle Timestamp, precision will be accurate to the second. For example, a value of 20171119T124745.006 will be saved as 20171119T124745. When you use Obj-Save, precision will be accurate to the millisecond. For more information, see DateTime property mapping in Oracle for Pega 7.
