How To Maintain Your Database

In your computer system, both hardware and software are tools. Like any tools, they require regular tune-ups to run smoothly. Checkups prevent minor difficulties from escalating and possibly causing system down time.

Run SCANDISK and DEFRAG often. These should be run monthly, or anytime the machines act up.

We recommend you backup critical data files before running maintenance since, if the machine is failing, the maintenance, while manipulating data files, may cause undesirable consequences and, potentially, loss of data.

tip.gif Please refer to Backup Database Topics for options for backing up your files.

Run database maintenance daily until you are sure your installation of Collect! is stable and error free. Once you have operated for a week, or so, without any errors reported during data maintenance, you can safely reduce the frequency with which you do your maintenance.

These recommendations should be considered according to the volume of data at stake. You want to be able to recover very quickly should anything unforeseen happen. Keeping a recent error-free backup of your Collect! database is your safest bet.

tip.gif You can also schedule maintenance routines to run off hours using Collect!'s Scheduler. Please refer to Help topic, Database Maintenance in Scheduler for details.

  • CV11 maintenance should be done directly at the server, not from a workstation.


  • The CV11 server should be running, but no users should be signed into Collect!, unless you are running only the DBCheck.


  • Sign into the database you wish to maintain. Make sure you are signed in using EXCLUSIVE mode, unless you are running only the DBCheck.


  • Select File from the top menu bar and then select Maintenance from the drop-down choices. This will display a side menu.


  • Select Maintenance from the choices presented. This will display the Database Maintenance form.


  • Select the START MAINTENANCE button on the Database Maintenance form to begin maintenance.


  • Let the routine run to completion without interference, noting any error messages which come up. Common sources of difficulty in running maintenance are dealt with below, in the Troubleshooting section. If any others arise, contact Collect! Technical Services for further assistance.

The rest of this document gives further details for the steps outlined so far.

To Run Maintenance

Make sure no users are attached to the Collect! files over the network. Make sure there are no db files open in WinNT Server Manager. If you find open files, close them to prevent corruption of the database. To be sure, reboot your server machine.

tip.gif These instructions are for running a full maintenance. If you only want to run DBCheck, please refer to the section entitled, Check Database.

1. Start CV11.

2. Sign in as a user with User Level 99.

3. Select the SELECT DATABASE button and choose the database you wish to maintain.

4. In the Database Access section, make sure there is a dot in the radio button labeled Exclusive.

5. Select the START button to sign into the database and stop at the Main Menu.

6. Select File from the top menu bar and then select Maintenance from the drop-down choices. This will display a side menu.

7. Select Maintenance from the choices presented. This will display the Database Maintenance form.

tip.gif There are many settings available for fine tuning your maintenance procedure. For details, please press F1 when the Database Maintenance form is displayed.

8. Select the START MAINTENANCE button to begin maintenance using the chosen settings.

By default, the maintenance procedure will rebuild database keys, sort the delete chain, run a check and dbfix, and a UID check on each of the databases that make up Collect!.

As each process runs, Collect! will update the message window.


Maintenance Running

tip.gif Some processes may take quite a while depending on the size of your database. If the process does not seem to be "moving" you can look at the CV11 Server (rds.exe) window for details.

When the maintenance completes, you will see a status report.


Maintenance Results

When maintenance is finished, you can select Application Log from the System, Diagnostics menu to open the Collect! Log Viewer which displays the results of the maintenance process. Press F1 for details when the Log Viewer is open.

Now that maintenance has completed successfully, backup your error-free database and store it in a safe location.

Troubleshooting CV11 Database Maintenance

RDM Server writes Server process information to the RDS.log file in the CV11\catalog folder. The RDS. log file is renamed to RDS#.bak when the RDS restarts. If you sort these files by date modified, you'll see the .bak files organized by the days in which they were created, extending back to the first day the RDS was in use on your system.

Whenever you experience errors, it is a good idea to check the entries in these .bak files for the appropriate day. Whenever the server reports an error, these logs show the particular error number and names of any files affected. This helps greatly to pinpoint the area you need to address and you can report this information to Technical Services when requesting assistance.

Partial Maintenance

When your database is very large, you may find it more efficient to maintain parts of the database at one time. Collect! ships with several utilities to assist you in this.

  • Three timed maintenance batch files are included. These batch files are explained below.
  • The Collect! database is structured with an individual file for each index key. You can easily reindex a particular key or a particular file. Please refer to How To Reindex Individual Fields for more information.

Timed Maintenance Batch Files

Sometimes we need to know how long a maintenance takes and what parts are taking the most time. Three timed batch files are included to provide these timing functions. If you are familiar with creating batch files, these files may be edited to run selective maintenance procedures.

These files are:

TIMEDRECFIX.BAT - runs the dbfix with the -r argument to check records only, and provide times for checking each record type.

TIMEDSETFIX.BAT - runs dbfix with the -s argument to check sets only and provides times for checking each set type.

TIMEDREINDEX.BAT - runs a keybuild and measures the time to rebuild each index file.

The results of these maintenance routines can be used to assess where time is taken during maintenance and to then construct a schedule of maintenance routines that run daily, maintaining parts of the database as time permits on each day.

To use these batch files:

1. Make sure the batch files are in your bin folder

2. When you would normally run your maintenance, try the TIMEDRECFIX batch file. With the RDM Server running, from the command line, type 'timedrecfix d01_collect' to maintain your demodb database or 'timedrecfix d00_collect' to maintain your masterdb database.

3. Examine the two log files created in the bin folder (refixlog.txt and refixlogdetail.txt). The first file shows elapsed times.

tip.gif The batch files assume you have an administrator account on the RDM Server userid=admin, pwd=secret. Please edit the files if you have different ID and Password.

tip.gif The other two batch files also create log files in the bin folder. After the maintenance test runs, just look for recently created text files in the bin folder and you will see the logs.

If you have any questions about the use or construction of these batch files please feel free to contact Collect! Technical Services.

Check Database

If you only want to check the state of your database, you can do this when users are logged into Collect!.

1. Start CV11.

2. Sign in as a user with User Level 99.

3. Select the SELECT DATABASE button and choose the database you wish to maintain.

4. Select the START button to sign into the database and stop at the Main Menu.

5. Select File from the top menu bar and then select Maintenance from the drop-down choices. This will display a side menu.

6. Select Maintenance from the choices presented. This will display the Database Maintenance form.

7. Select the CONFIGURE button to display the Database Maintenance Options form.

8. Ensure that only the "Check records, sets and blobs" choice is selected.

9. Select the RUN FUNCTION button to begin the database check.

When maintenance is finished, you can select Application Log from the System, Diagnostics menu to open the Collect! Log Viewer which displays the results of the maintenance process.

If errors are found, you can run a targeted fix, rather than your whole system.

Dbanalyze Utility

Collect! ships with a utility that may be used to check the state of all the files in all your databases. This is very handy because it can run when users are signed in. If errors are found, you can run a targeted fix on a single database, rather than your whole system.

The DBAnalyze utility checks the catalog as well as devices. It can be run with arguments to target only your working database.

Please refer to Help topic, Dbanalyze Utility for details and examples of running a targeted fix.
