================================================================================
Closed Issues in 5.2.2_HF-006 (This Release)
================================================================================

BE-24509
For Oracle 12, database connections were not closed properly when the query 
included a link to a remote database.
This was fixed. Now, set the CDD property be.dbconcepts.oracle.pool.v12 to true.
TIBCO BusinessEvents then uses the new pool for the Oracle 12 driver.
Note: For JDBC, copy ojdbc7.jar and ucp.jar to the {BE_HOME}\lib\ext\tpcl folder.

BE-24571
TIBCO BusinessEvents WebStudio became unresponsive after the importing decision
table from the Microsoft Excel file.

BE-24474
The state machine timeouts were not working and as a result the cache size was 
growing. 
This was fixed. Now, set the CDD property be.engine.cluster.as.remote.tuple.limit
to control the tuple data, sent from seeders to client, to prevent reaching the 
ActiveSpaces threshold.
