Error Message: Unable to open message file: PROMSGS

This error typically arises when the Progress PROMSGS environment variable is not set. If you are receiving such errors, follow the guide for your driver architecture --

Multi-Tier Drivers

1. Use a text editor to open the active Rulebook (default, <OPENLINK_INSTALL>/bin/oplrqb.ini).
   
2. Locate the [Environment PROGRESSXXX] section which corresponds to your database agent. For example:
   
   

   
   [Environment PROGRESS82A]
   DLC = C:/Pro82aDLC
   Path = C:/Pro82aDLC/BIN;D:/WINNT/System32
   ;PROMSGS = C:/DLC
   

   
   
3. Insure that PROMSGS is uncommented (no leading semicolon, ";") and set to the full path to your local promsgs file. For example:
   
   

   
   [Environment PROGRESS82A] 
   DLC = C:/Pro82aDLC 
   Path = C:/Pro82aDLC/BIN;D:/WINNT/System32 
   PROMSGS = C:/Pro82aDLC/bin/promsgs
   

   
   
4. Save your changes and exit the file.
   
5. Restart your Broker and test.

Single-Tier Drivers

1. Open the System control panel.
   
2. Set the variable on the Environment or Advanced tab. If you have a choice between System and User variables, set this under System. For example:
   
   

   
   PROMSGS    C:/DLC/bin/promsgs
   

   
   
3. If you do not have the System utility, you will need to set PROMSGS in your autoexec.bat. You will also need to reboot. Here is a sample autoexec.bat entry:
   
   

   
   set PROMSGS=C:/DLC/bin/promsgs
   

   
   
4. Test.
