Hello,
<div><br>
</div>
<div>We are about to implement RT as a core service and want to add its DB to an existing Postgresql cluster which we fail over to an alternate site when we think that the DB service will be unavailable for more than 2 hours due to power loss or network failures
or some other unfortunate event. The Postgresql write ahead logs are rsynched to the alternate site and applied to the DB there which is in stand-by mode. When we promote it to the primary we change DNS service name entries to point to it. It takes about
30 minutes to execute a fail-over.
<div><br>
</div>
<div>We will be running RT 4.0.6 on CentOS 6.2 x86_64 and the database will be Postgresql 8.4.7 on RH Linux.</div>
<div><br>
</div>
<div>Has anyone run RT in this kind of environment? </div>
<div><br>
</div>
<div>best regards and thanks in advance,</div>
