In the recent RAC SIG webcast, and during conversations with various customers, several specific questions often come up. This blog will address some of them.
Q: Does the RHP Server need to be a RAC Cluster?
A: No. The RHP Server code is part of Grid Infrastructure, so all that is needed is a GI installation of one or more nodes.
Of course a multi-node cluster provides HA for the RHP Server, but targets and RHP Clients operate independently of the server, and function normally whether the server is online or not. (If the RHPS is offline, RHP Clients cannot execute rhpctl commands, but are otherwise unaffected.)
Q: Does the RHP Server need to be running the same OS at the targets it manages?
A: No. The RHP Server can be Linux, Solaris or AIX, and the targets can be any mix of the same.
Note that Windows is not supported - neither as an RHP Server nor as a target.
Q: In order for RHP to manage my existing Database estate, do I need to install any software on the existing deployments, or configure the servers in any way?
A: No - no configuration updates, no agents, no daemons - all you need is connectivity from the RHPS to the machines you wish to manage.
From that point you can provision new Database, Grid Infrastructure etc. homes, and perform patching and upgrade operations on existing homes.
Q: The RHP collateral details capabilities for provisioning and maintaining DB and Grid homes. Can RHP manage other types of software?
A; Yes, RHP can provision and manage any type of software home. An RHP admin can create an arbitrary Gold Image type, and assign images to the new type. In addition, custom workflows can be associated with the new type, to handle operations for images of that category.
Any number of new types can be defined, each with its own custom workflows.
Coming soon: Q & A for specific scenarios such as patching in Oracle RAC, OJVM and Oracle Data Guard environments.
And of course answers to any questions you post !
