3.4.0 Matrix Server Command Reference

Chapter 2: mx Commands 84

[--frequency <seconds>]

The interval of time, in seconds, at which the monitor runs the probe. The

default is 10 seconds.

[--restarts <number of restarts>]

The number of attempts that should be made to restart the SQL service

instead of immediately failing over the Virtual SQL Server. If you do not

specify a number for this component, the Virtual SQL Server will fail over

immediately to a backup node.

[--probeSeverity nofailover|autorecover|noautorecover]

This setting determines what happens when the SQL monitor probe fails.

With nofailover, when the monitor probe fails, the Virtual SQL Server does

not fail over to a backup node. With autorecover, the Virtual SQL Server

fails over when the monitor probe fails, and failback occurs according to the

Virtual SQL Server policy (either

AUTOFAILBACK or NOFAILBACK). With

noautorecover, failover occurs to a backup node and the monitor is disabled

on the original node.

[--ordering SERIAL|PARALLEL]

Whether PolyServe Matrix Server enforces a strict ordering sequence when

it runs Start or Stop scripts. The default is serial, the strict ordering

sequence.

[--recoveryScript <script>]

Runs after a monitor probe failure is detected, in an attempt to restore the

SQL service.

[--recoveryTimeout <seconds>]

The amount of time to wait for the script to complete.

[--startScript <script>]

When PolyServe Matrix Server selects the active server for the SQL service,

the Start script runs on that server.

[--stopScript <script>]

A script that runs on all other servers configured for the monitor to ensure

that the SQL service is not active on those servers.

[--startTimeout <seconds>]

The amount of time to wait for the Start script to complete.
