==How can executables be changed to Enable or Disable use of SHLIB_PATH environment variable==

HP-UX has a <b>chatr</b>  command that allows the attributes on an executable to be viewed and changed. With this command you can specifically check if an executable has been built to use the <b>SHLIB_PATH</b> environment variable to locate shared libraries it may need, using commands of the form:

{{{
chatr <executable-name>                       ;;; list <executable-name> internal attributes

chatr +s enable <executable-name>             ;;; enable SHLIB_PATH usage attribute

chatr +s disable <executable-name>            ;;; disable SHLIB_PATH usage attribute
}}}

Example for the UDA Informix 9 database agent (inf9_mv) are as below:

{{{
