How do I use uvbackup to validate my database files?

To verify the integrity of your database files, you can run what is commonly referred to as a “dummy backup” using uvbackup. This utility goes through the motions of a backup without actually saving anything. This forces all file groups to be touched, thereby triggering a file corruption message if a corrupt file is encountered.

To verify a single file, provide the path to the file:

find /u2/eclipse/PRODUCT -print|uvbackup -limit 1 -f -v -notag - >/dev/null

To verify an entire database, provide the path to the live or restored database directory (i.e. /u2/eclipse, /mnt/rd1000/rsync/backup-20120130.2000/u2/eclipse):

find /u2/eclipse -print|uvbackup -limit 1 -f -v -notag - >/dev/null

Testing Printer Driver Performance Using Formscape

Preparing for Testing

Download TestHandles.fsp: http://cl.ly/DdNr/TestHandles.fsp

Double-click to launch Eclipse Forms Designer

If this is your first time using the Designer, you will need to enter your server name (localhost) and credentials

If you are not licensed for Designer, you will need to contact Eclipse support for a temporary license.

Testing for Performance or Resource Leaks

Here’s the procedure for testing for resource (i.e. handle) leaks. The same procedure may be followed to test for general performance (i.e. CPU, memory utilization) by monitoring the appropriate resources in taskmgr or Process Explorer.

Launch the task manager (Start → Run → taskmgr → OK)

Go to the “Processes” tab

Select “View” → “Select columns…”, verify that “Handle Count” is selected, and press OK

Locate the “fsshellw.exe” process and note its current handle count

Back in Designer, click the “” icon next to “Printer Name”

Enter the name of the printer to be tested, and press OK

If you would like to test more pages than the default 100, expand “Definition”, click the icon next to “Data”, enter the desired number of pages to “print” for testing in “The number to end the loop at” box, and press OK

Right-click the “Definition – Scan” button, and select Run

While the process is running, you will see activity in the bottom pane

After the process has completed, take note of the handle count for the “fsshellw.exe” process

The number of handles should not have increased substantially. If the print driver has a handle leak, this number will continue to grow as more test pages are “printed”.

Where can I purchase a USB modem?

MultiTech has discontinued the only USB modem that works with VSI-FAX, but the working MT5634ZBA-USB model is still available elsewhere. We suggest starting with an eBay search, which has worked well for a number of customers seeking replacement modems in a pinch. All of the typical eBay caveats apply (i.e. purchase from a reputable seller, make sure there’s a return policy, verify the warranty status, etc.).

Please note that while the model numbers are similar, this is not the same modem as the newer MT5634ZBA-USB-V92 model, which is not certified for use with VSI-FAX on Linux.
