| This page is intended to inform the EPICS community of the development status of VDCT. It meant to complement the information on the Cosylab page, not duplicate it. | | This Wiki page is now obselete. |
| | |
| | VisualDCT is now managed using the [https://github.com/epics-extensions/VisualDCT project at Github] and has its own [http://www.aps.anl.gov/epics/extensions/vdct/index.php EPICS Extensions webpage]. |

| VDCT is the Visual Database Configuration Tool. We hope that it we become the standard database configuration tool.

The code development is being done by Cosylab. | | VDCT (also known as VisualDCT) is the Visual Database Configuration Tool. It began as a project funded by the Swiss Light Source and developed by [http://www.cosylab.com Cosylab]. Later development was funded by the APS, Diamond and the SNS. The code is maintained by Cosylab under a Free Software license (GPLv3). Source code and binaries are available from the Cosylab web site. |
| | |
| Cosylab and the SLS have kindly made VDCT available under an open source license. Source code and binaries are available from the Cosylab web site.

| I ([mailto:Nick.Rees_at_diamond.ac.uk Nick Rees], of [http://www.diamond.ac.uk Diamond Light Source]) try to act as the interface person between the EPICS community and Cosylab.

| | |
| === Where to find it ===
| |
| The main place for things VDCT is the [http://www.cosylab.com/customer_area.php?mid=6&sid=26&ssid=2 Cosylab page]. Go to this page and click on the link under Builds. Here you will find links to the latest binaries, documentation, release notes and other useful information.
| |
| | |
| === Installation Tips ===
| |
| | |
| You don't need to build VDCT to install it. You can just get hold of the binary files and run it. You will need V1.4 or greater of the Java Runtime Environment to run it. These notes refer to build 1249. Check that there are not later builds available before you download.
| |
| | |
| # Go [http://www.cosylab.com/visualdct/builds/VisualDCT/ here] at the CosyLab site and click on the latest build number (at the time of writing this is"2.3.1249") under the "Distribution" heading.
| |
| # On this page again click on the build number under the Distribution heading This should begin the download of the distribution zip file.
| |
| # Save the zip file somewhere convenient.
| |
| # Unzip the zip file, to somewhere convenient. On Windows systems a "vdct" directory in the "Program Files" directory seems a good place.
| |
| # You should then see a "2.3.1249" directory. In that you'll see a file named "runScript".
| |
| # Execute the file named "runScript" and VDCT should start. On windows systems you will have to rename "runScript" to "runSript.bat" first.
| |
| | |
| === Current Status ===
| |
| As of 31 May 2005.
| |
| | |
| The current build is 1249. This is the package C release. The known bugs are listed on the Cosylab web site. See the [http://www.cosylab.com/visualdct/builds/VisualDCT/2.4.1249/index.html Change Log] on the Cosylab Page.
| |
| | |
| If you find any bugs not mentioned, please report them [mailto:[email protected] here]. | |
| | |
| === Wish list - Possible long term requirements ===
| |
| These are things that people have come up with as "wouldn't it be nice if" (WIBNIf) ideas. They may or may not get implemented. In true EPICS tradition, if you really want something the best way to get it is to fund the development or contribute effort.

| === Useful Tools ===
| |
| Following the standard laid down in the Application Developers Guide, VDCT requires record names to be enclosed in double quotes. This can cause a problem if you try to read a database that's been created on a text editor.
| |
| | |
| If you attempt to read a database in to VDCT that has macro substitution fields in the record name but does not have double quotes around the record names you will see an error. e.g. a database file with record names like this:
| |
| | |
| <pre>
| |
| record(sub,$(dev):StandardizeSUB) {
| |
| .
| |
| .
| |
| }
| |
| record(ai,$(dev):CurrentAI) {
| |
| .
| |
| .
| |
| }
| |
| </pre>
| |
| | |
| Will produce this error on the VDCT console:
| |
| | |
| <pre>Warning: Record with name '$' already exists, skiping...</pre>
| |
| | |
| The following perl script processes database files, adding quotes to record names when required.
