Table 16-36 Options for the acfsutil repl sync command
| Option | Description |
|---|---|
|
|
Specifies that all changes be applied to the standby file system. |
|
|
Specifies the directory where the primary file system is mounted. |
You can use the acfsutil repl sync command to synchronize the state of the primary and standby file system. This command can only be run on the site hosting the primary file system.
You should first quiesce your applications and run a sync(1) call so that the synchronized state is known and meaningful to you. The acfsutil repl sync command then causes all outstanding replication data to be shipped from the primary to the standby file system.
The acfsutil repl sync command returns success when this transfer is complete or, if the apply parameter is supplied, when all of these changes have been successfully applied to the standby file system. At this point, unless an unmount of the last node on the primary site cluster is about to occur, applications can be restarted. You can use the acfsutil repl sync command before dismounting the file system on the last node to ensure that all modifications have been sent to the standby file system.
If acfsutil repl info -c reports the primary file system is in the Initializing state, the acfsutil repl sync command does not guarantee that all files to be replicated in the file system have been sent to the standby file system. Files that existed in the file system before running the acfsutil repl init command are sent to the standby file system in the background.
You must have system administrator or Oracle ASM administrator privileges to run this command.
