Q. What does WML stand for?
A. WML refers to Web+ Markup Language. It was developed by Webplus in 1995 and is a powerful and comprehensive development language for use in creating web-based client server applications without writing complicated, low-level and time consuming CGI programs. It is similar to Cold Fusion, ihtml, and ASP, only it's faster and more functional.
Q. Where can I download the free version of Webplus 4.6?
A. You can download a Free (BETA) Evaluation Version of Web+ 4.6 . The Web+ client for Linux (webplus.cgi) is also available for you to test connection to Web+ server on NT which will allow you to link to an Access database from a Linux web server.
Q. Can Web+ handle high-volume server databases?
A. Yes, we've been using Webplus's Web+ (http://www.webplus.com) for high volume database web sites using Apache web server on Linux or IIS on NT to connect to Access, dBase, SQL Server on NT, or mySQL or miniSQL for Linux.
The following are two important features of Web+ for supporting high volume database web sites:
1. Support for multiple platforms and mixed NT and Unix platforms: Windows NT, Windows 95, Linux, Sun Solaris. (Other Unix platforms available soon). Web+ is the only web to database connectivity tool that supports mixed platforms (mixing Windows NT/95 and Unix). With Web+, you can connect your Unix/Linux (or NT) based web servers with NT/Win95 based databases such as Access, dBase, FoxPro, Paradox, etc. Web+ client (webplus.exe) can communicate with Web+ server (executable version: webpsvr.exe ; or NT service version webpsvc.exe) on the same or on a different server, either NT or UNIX platform (mixed platform).
2. Support for distributed, multi-threaded, client/server computing. Companies can run their Web+ application on a different machine from the one on which they run their Web server. Distributed computing is a proven technique for scaling, linking to existing corporate systems, improving system availability, and improving security via compartmentalization, such as firewalls. This provides application independence and improved fault tolerance: if one Web+ application crashes on an independent Web+ server, it will not affect the performance of the web server or other Web+ application servers.
Q. How do I manually upgrade a Web+ (v3.0) service version?
A. if you need to upgrade your Web+ service (webpsvc.exe file) just follow these steps:
1. Stop your current "Webplus Web+ Server" service in your NT Control Panel.
2. Remove your old Web+ service. At DOS command prompt (you should see c:\webplus\instwsvc.exe, which is the Web+ NT service installation program ), type: cd c:\webplus\bin instwsvc remove.
3. Replace your current c:\webplus\bin\webpsvc.exe with the new webpsvc.exe. Please make a backup copy of your old webpsvc.exe.
4. Install the new Web+ NT service. At DOS command prompt, type:
cd c:\webplus\bin
instwsvc c:\webplus\bin\webpsvc.exe
5. Goto your NT Control Panel and start "Webplus Web+ Server" service.
6. You've finished setting up your new Web+ NT service. If everything goes well, you should see the following in you Web+ log:

Q. Can Web+ handle cross-platform in different environments?
A. I believe that Web+ is the only web to database connectivity tool that supports mixed platforms (mixing Windows NT/95 and Unix). With Web+, you can connect your Unix/Linux (or NT) based web servers with NT/Win95 based databases such as Access, dBase, FoxPro, Paradox, etc.
You can use Web+ on Unix/Linux to access your MS SQL Server (or Access, dbase, FoxPro, etc) on WinNT or other databases on Unix by either:
1. installing a Web+ Server on WinNT, this way the Web+ Client on Unix communicates with the Web+ Server on WinNT using TCP/IP sockets, or
2. installing both Web+ Client and Web+ Server on Unix (the same machine) with a ODBC driver for Linux (this option requires Linux ODBC drivers).
The following diagram illustrates the Web+ client/server architecture and it's middleware nature for web-to-database connectivity:
1. Web Browser [any hardware/OS]
(Internet/Intranet)
2. Web Server [any web server or OS, eg. NT/Unix]
(CGI/ISAPI)
3. Web+ Client [any OS, eg. NT/Unix]
(TCP/IP Socket)
4. Web+ Server [any OS, eg. NT/Unix]
(ODBC Driver)
5. Database [any ODBC database, any OS, eg. WinNT]
Q. My Web+ License ID expired. How do I manually install the Web+ License ID?
A. To fix the problem, we are requesting you to replace your old Web+ 4.6 LicenseID with the new permanent LicenseID in your Web+ server configuration file (e.g.. c:/winnt/webpsvr.ini) .
Warning:
Web+ 4.6 License IDs are not compatible with Web+ 3.0 License IDs. Please contact the Webplus Sales Team should you desire to upgrade a previous version of Web+.
Procedure:
1. Stop your Web+ Server (under NT Control Panel, Services, Webplus Web+ Server).
2. Open your webpsvr.ini in your Windows directory with a text editor (such as notepad.exe). Look for the LicenseID= parameter under the [Main] section and set it to your new LicenseID.
Your c:\windows\webpsvr.ini
[Main]
;Main Section
;Encrypted LicenseID assigned by Webplus
LicenseID=paste your new LicenseID here
3. Restart your Web+ Server.
Q. How to install the ODBC Driver Manager?
A. 1. .Run pkgadd to begin the installation. % pkgadd -d /cdrom/cdrom0/ODBC2.11/sparc
2.Answer the questions prompted by the pkgadd command? Just choose default choice.
3.After successfully installing ODBC, you may find the installed package under /opt/ISLIodbc/2.11. This is the home directory of ODBC.
4.Setup necessary environment to enable odbc to find its shared library and resource files (required)
a. Setup environment.
If you use C-shell, type % source /opt/ISLIodbc/2.11/.odbc.csh
If you use Bourne or Korn Shell, type % source /opt/ISLIodbc/2.11/.odbc.sh
Every time, you want to use ODBC, you should do this. You may also put the yellow highlighted line into .cshrc file under your home directory or green high lighted line into your .shrc file under your home directory. This can let the system execute the setting up automatically.
b. Setup resource files. You must configure ODBC drivers through the .odbc.ini file. This file is a plain text file. It stores ODBC configuration and connection used by the Driver Manager. .odbc.ini normally resides in the users' $HOME directory. It is maintained manually using any editor. System administrators can also maintain a centralized copy of .odbc.ini that they can control.
You can get a copy of .odbc.ini file from /opt/ISLIodbc/2.11/.odbc.ini and use it as a template. You may make some necessary changes on it to fit your need.
Here is an example to make the demo program run:
1) copy files demoodbc and EMP.DBF under /opt/ISLIodbc/2.11/demo to your home directory. 2) Create .odbc.ini file:
;---------------------------------------------------
; ODBC.INI - INTERSOLV ODBC Driver Manager INI File
;---------------------------------------------------
[ODBC Data Sources]
qedbf=dBASE
[qedbf]
Driver=/opt/ISLIodbc/2.11/drivers/qedbf08.so
Description=INTERSOLV dBASE driver
DSN=EMP.DBF;LCK=NONE;IS=0
3) type "demoodbc qedbf" to see the demo.
Q. I just installed the Web+ Desktop evaluation and I am encountering the following error within the Server Manager:
Error Code = 10810
A. Explanation = Cannot use the variable 'client.LocalST' to do an operation without first defining it.
Troubleshooting Information = Check the script and make sure that the variable is properly defined before being used.
To solve this problem use parameter UCID=IP on webclient tags.
Q. How do I debug, troubleshoot Web+ problems?
A. Accomplish the following to debug/troubleshoot Web+ problems:
1. Go to your Web+ Administration Manager, Log Section (or directly go to your c:\winnt\webpsvr.ini, Log section) and set your LogLevel = 1 , highest level. LogLevel=1 will cause some performance degradation but it generates very detailed log file under c:\webplus\log\webplus.log .
2. If you changed webpsvr.ini manually, restart the Webplus Web+ Server service to re-initiate the new ini settings. If you use Web+ Administration Manager, clicking the Update button refreshes the ini settings.
3. Study your c:\webplus\log\webplus.log file. It tells you in the beginning section whether the ODBC connection is successful or not. If not, check your ODBC connection in Windows Control Panel, DSN, and make sure that the ODBC datasources are set up properly in the system level, this is the prerequisite for Web+ server.
4. Can you reproduce the problem in a regular basis? If so, please send us the templates and the database (as attachments) so that we can debug it in our tech support center.
5. If you want to get technical support from us, please always set LogLevel=1 in your webpsvr.ini and send us your webplus.log. By looking at the log file, we'll be able to debug your problems more effectively. If you can the above steps yourself first and provide us the above info when requesting for technical support, we will help you debug your problems quickly and accurately
Q. I am experiencing performance drops on my Webserver. What should I do to increase performance?
A. For a high-traffic database web site, the important issues to consider are hardware scalability, distributed processing, and client/server web application architecture. You may want to physically separate your web application server and/or database server from your web server in order to achieve maximum performance and fault tolerance.
Web+ cannot connect to ODBC datasource even though MS Query (or other ODBC query tools) can access the datasource. Control Panel ODBC Datasources shows the datasource. ODBC user DSN was configured for SampleDB but not System DSN.
Webplus.log shows: Pre-Connection to Datasource SampleDB failed.
Web+ requires System DSN to be defined. It is an important distinction that you should probably re-check you Control Panel, ODBC icon, System DSN button, and see if your datasources are properly defined in the System DSN.
Once you define ODBC System DSN for SampleDB, Web+ should connect to it and work normally.
Q. I received this Error 10020. Can you help me?
A. When the Web+ server is first starter, check the webplus.log file. There is an "ODBC" section. Check the status when it tries to connect to that data source. If it fails to connect, it will probably provide a clue as to what the problem is. Also, check to see if other ODBC applications can access your data source.
