Uninstalling MessageQ V3.x and V4.x

 

Perform the following steps to uninstall MessageQ V3.x or V4.x installations from your system:

1. Determine if version 3.x or 4.x is installed. If you are unsure of whether or not you have a previous installation of BEA MessageQ installed, enter the following command:

   # ls -l /usr/bin/dmqqe

   If this file exists, then an older version of MessageQ is installed and you should proceed with these instructions.

2. Log in as root. If you are not already logged in as root (superuser), do so now. You must be logged in as root in order to deinstall previous versions of MessageQ.

3. Determine what MessageQ version and components are installed by issuing the following command:

   # setld -i | grep -i MessageQ

   The output will look something like this (the output and installed component names differ from machine to machine):

   # setld -i | grep -i MessageQ
   DMACL32B                        MessageQ Client Library
   DMACL40A             installed  MessageQ Client Library
   DMACLS32B                       MessageQ Client Library Server
   DMADEV32B                       MessageQ Development Environment
   DMADEV40A            installed  MessageQ Development Environment
   DMADOC40A            installed  MessageQ Online Documentation
   DMAEXA32B                       MessageQ Example Programs
   DMAEXA40A            installed  MessageQ Example Programs
   DMAINC40A            installed  MessageQ Include Files
   DMAMAN32B                       MessageQ Manual Reference Pages
   DMARLS32B                       MessageQ Release Notes
   DMARLS40A            installed  MessageQ Release Notes
   DMARTO32B                       MessageQ Run Time Environment
   DMARTO40A            installed  MessageQ Run Time Environment
   #

   If the setld command can not be found or setld did not find any installed components, issue the command from the /etc/ directory as follows:

   #/etc/setld -i | grep -i MessageQ

   If /etc/setld does not exist or /etc/setld did not find any installed components, call your BEA Systems support representative for additional help in removing the previous version of MessageQ. Note that if you do not remove versions of MessageQ prior to version V5.0, you may experience serious operational problems with your new installation.

4. Remove the installed components. Issue either setld -d (or /etc/setld -d if /etc/setld was used in Step3) to remove the installed components. Notice in the example above that some components are installed and others are not installed; only remove the installed components. Using the example in Step 3, the command would look like this (split here into two calls to setld):

   #setld -d DMACL40A DMADEV40A DMADOC40A DMAEXA40A
   #setld -d DMAINC40A DMARLS40A DMARTO40A

   The output from this will look something like this:

   # setld -d DMACL40A DMADEV40A DMADOC40A DMAEXA40A

   Deleting "MessageQ Example Programs" (DMAEXA40A).

   Deleting "MessageQ Online Documentation" (DMADOC40A).

   Deleting "MessageQ Client Library" (DMACL40A).

   Deleting "MessageQ Development Environment" (DMADEV40A).
   # setld -d DMAINC40A DMARLS40A DMARTO40A

   Deleting "MessageQ Release Notes" (DMARLS40A).

   Deleting "MessageQ Run Time Environment" (DMARTO40A).

   Deleting "MessageQ Include Files" (DMAINC40A).
   #

5. Confirm that the older version has been removed and that setld removed everything by re-issuing the setld -i (or /etc/setld -i) command:

   # setld -i | grep -i MessageQ
   DMACL32B                        MessageQ Client Library
   DMACL40A                        MessageQ Client Library
   DMACLS32B                       MessageQ Client Library Server
   DMADEV32B                       MessageQ Development Environment
   DMADEV40A                       MessageQ Development Environment
   DMADOC40A                       MessageQ Online Documentation
   DMAEXA32B                       MessageQ Example Programs
   DMAEXA40A                       MessageQ Example Programs
   DMAINC40A                       MessageQ Include Files
   DMAMAN32B                       MessageQ Manual Reference Pages
   DMARLS32B                       MessageQ Release Notes
   DMARLS40A                       MessageQ Release Notes
   DMARTO32B                       MessageQ Run Time Environment
   DMARTO40A                       MessageQ Run Time Environment
   #

   If nothing is marked as being "installed", you are done with setld. To be sure, look for installed files that may not have been removed by issuing the following command:

   # ls -l /usr/bin/dmq* /usr/lib/dmq*

   If all files have been removed, no files will be found by the command. If you can not remove all of the MessageQ components, contact you BEA Systems support representative for additional help.
