Rolling Patch - OPatch Support f...question 22 wrong<br />Rolling Patch - OPatch Support for RAC (Doc ID 244241.1)<br /><br />1 - RAC Patching methods<br /><br />OPatch supports 3 different patch methods on a RAC environment:<br /><br /> Patching RAC as a single instance (All-Node Patch)<br /><br /> In this mode, OPatch applies the patch to the local node first, then propagates the patch to all the other nodes, and finally updates the inventory. All instances must be down during the whole patching process.<br /><br /> Patching RAC using a minimum down-time strategy (Min. Downtime Patch)<br /><br /> In this mode, OPatch patches the local node, asks users for a sub-set of nodes, which will be the first subset of nodes to be patched. After the initial subset of nodes are patched, Opatch propagates the patch to the other nodes and finally updates the inventory. The downtime would happen between the shutdown of the second subset of nodes and the startup of the initial subset of nodes patched.<br /><br /> Patching RAC using a rolling strategy - No down time (Rolling Patch)<br /> With this method, there is no downtime. Each node would be patched and brought up while all the other nodes are up and running, resulting in no disruption of the system.<br /> <br />---- Minimum downtime -----<br /><br /> . Shutdown the Oracle instance on node 1<br /> . Apply the patch to the RAC home on node 1<br /> . Shutdown the Oracle instance on node 2<br /> . Apply the patch to the RAC home on node 2<br /> . Shutdown the Oracle instance on node 3<br /> . At this point, instances on nodes 1 and 2 can be brought up<br /> . Apply the patch to the RAC home on node 3<br /> . Startup the Oracle instance on node 3<br /><br />C wrong ( nodes are always available )djeday84https://www.blogger.com/profile/15872287264425110881noreply@blogger.com
