Configure the MinimumSnapShotInterval Setting

Meridian maintains a transaction log file for each vault database that contains all changes made to the vault since the log was last committed to the database and a snapshot was created. When the amount of time specified by the MinimumSnapshotInterval setting has elapsed, the log is committed to the database and a new snapshot is created.

This setting works together with the MaximumLogSize (in MB) setting. For example, if MaximumLogSize is set to 8 (default) and MinimumSnapshotInterval is set to 240 (default), when the log file reaches 8 MB, no snapshot will be created unless 240 minutes (4 hours) has elapsed since the last snapshot. Likewise, if 240 minutes (4 hours) has elapsed since the last snapshot, a new snapshot will not be created until the log file size is at least 8 MB.

The primary purpose of MinimumSnapshotInterval is to allow a System Administrator to prevent a snapshot from occurring during production hours (as a result of MaximumLogSize being met) when an extraordinary number of changes are made to the vault (such as a batch import), which would adversely affect performance.

Note:

Whenever a Prepare for Backup operation occurs, the log is committed to the database and a new snapshot is created.

This setting can also be configured with the MinimumSnapshotInterval registry key located at:

HKEY_LOCAL_MACHINE\SOFTWARE\Cyco\AutoManager Meridian\CurrentVersion\Installed DataStores\<VaultName>\CompoundItemService\MinimumSnapshotInterval

ClosedTemporarily Disable Snapshot Creation

To temporarily disable snapshot file creation during large batch operations:

  1. Navigate to the following registry key on the Meridian application server:

    HKEY_LOCAL_MACHINE\SOFTWARE\Cyco\AutoManager Meridian\CurrentVersion\Installed DataStores\<VaultName>\CompoundItemService

  2. Create a AllowSnapShot DWORD registry value.

  3. Set AllowSnapShot to 0 to disable creation of new snapshots.

  4. Stop the AutoManager EDM Server service.

  5. Restart the AutoManager EDM Server service.

  6. Begin the batch operation.

  7. Wait for the batch operation to complete.

  8. Navigate back to the registry key listed in step 1.

  9. Set AllowSnapShot to 1 to enable creation of new snapshots.
