Changes to Default Settings and Reserved Words

Replication Server 15.5 includes changes to default settings and values to accommodate the enhancements in Replication Server and improve performance.

• Changes to Parameter Default Values
  Except for memory_limit and smp_enable, if you upgrade to Replication Server 15.5, the only values that are set to the new defaults are those that used the defaults in the earlier version.
• Changes to the RSSD Locking Schema
  To reduce contention and improve performance, the default locking schema for the system tables in the Replication Server System Database (RSSD) is row-level locking when you install or upgrade to version 15.5.
• Reserved Words
  Version 15.5 adds to the list of reserved Replication Server keywords.
