Recover database from old backup
When the Scalar DLC database is lost and there is only the backup from previous version of Scalar DLC
(for example, 2.4), the recovery is possible.
Step 1
Restore the Scalar DLC database from a backup, as described in
Restore Scalar DLC
Database
on page 106.
Step 2
Launch
Start > Settings > Control Panel > Administrative Tools > Add-Remove Programs
> Scalar DLC
and press Change. The Scalar DLC Add/Remove engine starts, as described in
Add/Remove Scalar DLC Software
on page 77.
Step 3
Select Repair, then Scalar DLC database, then Upgrade (see
Figure 45
on page 81). The
database will be upgraded. Restart is required thereafter.
Step 4
After the restart, log on the Management GUI and review the existing configuration. It is
possible that manual improvement is needed. See
Scalar DLC Reference Guide, Advanced
Configuration
section for more details.
Step 5
After the configuration is performed, backup the new database to a archive file on RAID or
floppy (see
Back up Scalar DLC Database
on page 105) and proceed the work.
Downgrading the Scalar DLC
In case of any serious inconvenience after upgrading Scalar DLC, it is possible to downgrade the Scalar
DLC back to previous level (database backup from this ‘previous/original level’ is required).
Do the following.
Step 1
Using Add/Remove programs remove the Scalar DLC 2.7 software (see
Remove
on page 78)
removing the database, too.
Step 2
From the same Add/Remove window, remove the Java software package.
Step 3
Review
<%System disk%>\Program Files
folder and remove ‘SDLC’ and ‘Apache Group’
folders manually if they are not removed.
Step 4
Install the original Scalar DLC. Apply all necessary Service packs and hot fixes (see
Installing
Scalar DLC Service Packs
on page 92).
CAUTION
Do NOT start the Scalar DLC now! It will not function.
