I have become disenchanted with RedHat Cluster Manager for Oracle installs. Having installed a number of these alongside Veritas (now Symantec) Cluster Server (VCS), we have found that the VCS is far more reliable. VCS now has an Oracle Agent that is Dataguard aware, so the previous limitation of using Dataguard broker in active / passive clusters has been addressed. VCS is only slightly more expensive that RH Clustering on Linux. Just be aware that you will probably need to use the Veritas volume manager / filesystem with VCS rather than GFS, but it's a very good solution when RAC costs too much. I highly recommend VCS. ________________________________ From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of Juan Cruz Miranda Vigo Sent: Sunday, February 21, 2010 5:21 PM To: oracle-l@xxxxxxxxxxxxx Subject: active-pasive cluster in linux Hi I need to configure an Oracle database into an active-pasive cluster in linux. As HP Serviceguard isn´t now available for linux I will go with RedHat Cluster but my past experiences with v4 aren´t good. I know I can use Oracle Clusterware to configure an active-pasive service but I don´t tried it. Are there other good alternatives? Please share your experiences with active-pasive clusters on linux. RAC isn´t a option here. thanks!
