How to prioritize databases in RAC during GI start.

Hello,

1.

We have a 4-node RAC with 7 databases - prod, test, other (7 lgwr processes in each host for clear).

Who knows - what is the order in which databases will start after clusterware restart ?  Alphabetical ? Time of creation ? any other ?

2.

I want to control the order my databases will start after OS/GI restart.

For example, i want to take the 1st priority to most important prod and start it first. Any other databases should be delayed for 5 minutes (to allow to first prod to allocate memory + warm buffer cache and work some minutes).

Then i want to choose 2nd priority prod and start it.
