The time of the failure is recorded in the DIVArchive database and the Checksum Status in the Control GUI is updated to Partially Verified.
EXPEDAT DROPLETS VERIFICATION
If a checksum failure occurs for one of the instances, the timestamp is recorded and the object status will be updated to Partially Verified.Ī restore of Instance A is made, however the checksum verification fails. If a checksum failure occurs for an instance, the corresponding object's checksum status will be updated.Īn object has two instances and the current object checksum status is Fully Verified. Whenever there is a checksum failure for a particular instance, the timestamp is stored for the instance in the database's Instance table. The checksum entered into the database is viewable in the bottom portion of the screen labeled Elements.Ĭhecksum failure dates are recorded in the DIVArchive database, however they are not (currently) displayed in the Control GUI. The Last Verify Date is viewable in the center portion of the screen labeled Instances.

In the following figure, although the highlighted object has not been verified, a checksum for that object was saved in the database. Verification did not succeed, or has not been performed, for at least one instance. Verification succeeded for at least one instance. Partially Verified (half green and half empty circle)įor objects with multiple instances this status appears if both of the following statements are true: The default checksum was used and the object has not been read-back for verification. The checksum has never been calculated because the object was archived in a software release before Oracle DIVArchive 6.4, or because it is a complex object. Verification has not been completed for this object. The Checksum column displays the following different status values: The status is identified by circles (empty, partially filled, or fully filled) and text.ĭouble-clicking on the resource opens the Object Properties dialog box showing verification or failure messages and checksum information.

The Archived Objects view shows the Checksum column, indicating the status of the checksum for any particular object in the system.

You view checksum verifications and failures through the Control GUI Manage tab in the Archived Objects view. This checksum is not verified until an initial read-back or Restore operation is performed.
EXPEDAT DROPLETS ARCHIVE
During the archive process, the checksum is generated real-time by the Actor and stored in the database.
