About OHASD in a single instance database environment

The Oracle Grid Infrastructure software provides system support for an Oracle database including Oracle Automatic Restart and Oracle ASM features.

On nodes that have Oracle Grid Infrastructure installed in a single instance database environment, ensure that the Oracle High Availability Services daemon (OHASD) process comes online before the Oracle resources.

Administration of Oracle resources on these nodes is dependent on the OHASD process. So, the process needs to be online first to ensure that the resources come online.
