Verifying configuration parameters  Creating a new default device other than master

Chapter 8: Configuring Adaptive Server for Failover on IBM AIX HACMP

Adding thresholds to the master log

If you have not already done so, add a threshold to the master log.

  1. Define and execute sp_thresholdaction on the master database’s log to set a threshold on the number of pages left before a dump transaction occurs. Sybase does not supply sp_thresholdaction. See the Adaptive Server Reference Manual for information about creating this system procedure.

  2. Place thresholds on the master and sybsystemprocs log segments so they do not fill up:

    sp_addthreshold "master", "logsegment", 250, sp_thresholdaction
    sp_addthreshold "sybsystemprocs", "logsegment", 250, sp_thresholdaction
    
  3. Perform both steps on the primary and secondary servers, then restart both servers to allow the static configuration parameters to take effect.
