Hi Christian,

I have changed as you mentioned, now the process did not launch when rebooted. Any other changes need to be done?


<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>KeepAlive</key>
    <true/>
    <key>Label</key>
    <string>com.guidancesoftware.encaseforensicservlet</string>
    <key>Program</key>

    <string>/usr/local/encase/EnCase</string>
    </array>
    <key>ProgramArguments</key>
    <array>
    <string>start</string>
    </array>

    <key>RunAtLoad</key>
    <true/>
</dict>
</plist>




Thanks & Regards,

I am by no means an expert, but have you tried this:

     <key>Program</key>
     <array>
     <string>/usr/local/encase/Encase</string>
     </array>
     <key>ProgramArguments</key>
     <array>
     <string>start</string>
     </array>

…which gives launchd a clue as to which binary it needs to keep alive.

Hi,

I am trying to create a Launch Daemon for EnCase binary file. I have to
add KeepAlive to the Launch Daemon plist. The process should be alive
even if it exists normally (with exit 0) or crashes with error.

I tried adding <key>KeepAlive</key> in the Launch Daemon(below) created
but this keeps on running the Program Arguments resulting in multiple
process of the same binary.

    <array>
    <string>/usr/local/encase/Encase</string>
    <string>start</string>
    </array>
    <key>QueueDirectories</key>

    <key>RunAtLoad</key>
    <true/>
    <key>WatchPaths</key>
    <array/>
    </dict>
    </plist>



Someone help me in changing the LauchDaemon plist so that the process
kickstart again if it exits?

Thanks & Regards,
Karthikeyan M
