Wing, prayer, rabbit's foot, four leaf clover... Sorry, couldn't resist.... :D Dataguard and logical standbys for Oracle, replication in SQL Server and "a poor man's RAC" for MySQL.

For Database, then you have DataGuard which in my experience covers most HA needs. You do have RAC, but RAC introduces a whole new level of complexity and therefore a new potential point of failure. As Niall mentioned you have various replication methods as well. I guess the real question is what is the business need (the REAL business need) and then we can tell you what kind of HA/replication we use. hth Alan.- On Wed, Oct 20, 2010 at 2:39 PM, Niall Litchfield <niall.litchfield_at_gmail.com> wrote: Standby, streams, replication, snap mirrors ....... >On 20 Oct 2010 18:14, "Michael Dinh" <mdinh_at_xifin.com> wrote: >> >> >>I am curious as to what options are available for HA and what you are using. >> >>I have the following list: >> >>Veritas Cluster Server >>VMware VMotion >>Oracle RAC >> >>Ideally, we want to stick with Solaris. >> >>Thanks. >> >>Michael Dinh >> >>NOTICE OF CONFIDENTIALITY - This material is intended for the use of the >>individual or entity to which it is addressed, and may contain information that >>is privileged, confidential and exempt from disclosure under applicable laws. >>BE FURTHER ADVISED THAT THIS EMAIL MAY CONTAIN PROTECTED HEALTH INFORMATION >>(PHI).
