12c Clusterware - An outlook

Thanks to Tim Hall. With the help of his notes i was able to successfully install my 1st 12C Grid Infrastructure. Except for few tweaking to the network interface cards. I just followed his notes as it is. In virtual box my guest is oel 6.5 and host is Windows 8.I tried executing few 11.2 commands and 12.1 just takes it like a vanilla.

We could see couple of new resources here as well.
1. ora.MGMTLSNR
2. ora.mgmtdb

One point i noticed the term STABLE in state_details does not have anything to represent the health of a resource. As per documentation this is the INTERNAL_STATE of a resource.

INTERNAL_STATE
An internally managed, read-only attribute that describes what, if any, action the policy engine is currently executing on the resource. Possible values and their meanings are as follows:

STARTING: The policy engine is currently starting the resource

STOPPING: The policy engine is currently stopping the resource

CLEANING: The policy engine is currently cleaning the resource

STABLE: The policy engine is not currently executing any action on the resource

Note, however, that the resource can still be locked as part of some other command.

After finishing this post i wanted to list all the daemons part of 12c CRS. While i was looking for further information on evmlogger, my bad!! i found out that a similar article is already published in Oracle support. 1517182.1
Happy reading!!!
