5.16 STTOR Phase 7

In QMGR the president starts an arbitrator (unless this feature has been disabled by setting the value of the ArbitrationRank configuration parameter to 0 for all nodes—see Defining an NDB Cluster Management Server, and Defining SQL and Other API Nodes in an NDB Cluster, for more information. In addition, checking of API nodes through heartbeats is activated.

Also during this phase, the BACKUP block sets the disk write speed to the value used following the completion of the restart. The master node during initial start also inserts the record keeping track of which backup ID is to be used next. The SUMA and DBTUX blocks set variables indicating start phase 7 has been completed, and that requests to DBTUX that occurs when running the redo log should no longer be ignored.
