I need to enable archivelog. But sometimes database can't connect archivelog destination (NFS disk) and shutdowns. I can set two archivelog destinations and one of them is not NFS disk (local disk).

How can I configure, if database can't connect to NFS disk (dest1), to just write on local disk (dest2) and continue to work?

Thank you.

You can use ALTERNATE attribute in second archive log destination.

ALTERNATE

Specifies an alternate archiving destination to be used when the original destination fails.

Example:

LOG_ARCHIVE_DEST_1='LOCATION=/disk1 MANDATORY ALTERNATE=LOG_ARCHIVE_DEST_2'
LOG_ARCHIVE_DEST_STATE_1=ENABLE
LOG_ARCHIVE_DEST_2='LOCATION=/disk2 MANDATORY'
LOG_ARCHIVE_DEST_STATE_2=ALTERNATE

Reference: LOG_ARCHIVE_DEST_n Parameter Attributes
