Problem
During the installation of the WebSphere Application Server plugin or installation of the plugin Interim Fix, the following error is recorded in the extractor.log:

Error 79 -- Unable to open destination file: /pwsprdmro2/was/4.0.3/bin/mod_ibm_app_server_http.so : /pwsprdmro2/was/4.0.3/bin/mod_ibm_app_server_http.so (Text file busy)
Error 18 -- Extraction failed: /pwsprdmro2/was/4.0.3/bin/mod_ibm_app_server_http.so
Command=chmod 755 /pwsprdmro2/was/4.0.3/bin/mod_ibm_app_server_http.so

The user indicated they are unable to install or remove the Interim Fix.
Finally, the user verified that no webserver or java processes were running.
 
Solution
There are two possible solutions to this problem:
  1. Prior to attempting to update, delete, move, or copy the WAS plugin (mod_ibm_app_server_http.so), the IBM HTTP Server should be shutdown using the "/usr/HTTPServer/bin/apachectl stop" command and then verify that no "httpd" processes are remaining by issuing "ps -ef | grep httpd". Use the "kill" command to terminate any remaining httpd processes and then attempt to update, delete, move, or copy the WAS plugin (mod_ibm_app_server_http.so)
  2. This error can also occur because a shared library is considered in-use by the kernel. Some shared libraries on AIX remain loaded even though there are no processes currently using the shared library. The way to tell the kernel to unload it is to issue the AIX command "slibclean" as root:
    # /usr/sbin/slibclean
  3. Move/rename the file (mod_ibm_app_server.http.so).

Once the file has been moved or renamed, you should then be able to apply or remove the Interim Fix.
