Re: [Virtuoso-users] How to start ./virtuoso-t with a non-forked/daemonized parameter? (Tim Haynes)

[Patrick van Kleef]

HI Ceriel,


I have tried to launchctl start virtuoso-t appended with the -f  
parameter:

<dict>
        <key>Disabled</key>
        <false/>
        <key>UserName</key>
        <string>root</string>
        <key>GroupName</key>
        <string>wheel</string>
        <key>Label</key>
        <string>com.openlinksw.vos</string>
        <key>Program</key>
        <string>/usr/local/virtuoso-opensource/bin/virtuoso-t</string>
        <key>ProgramArguments</key>
        <array>
                <string>-f</string>
        </array>
        <key>KeepAlive</key>
        <dict>
                <key>SuccessfulExit</key>
                <false/>
        </dict>
        <key>WorkingDirectory</key>
        <string>/usr/local/virtuoso-opensource/var/lib/virtuoso/db/</string>
</dict>

that didn't change the behaviour:


The problem is that the documentation talks about the ProgramArguments  
as being the second parameter to the excecvp(3) function, which  
basically is an ARGV[] array. This means that just like with a C  
program you need to specify argv[0] as the program name.

So a working launch control file is:

  <?xml version="1.0" encoding="UTF-8"?>
  <!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" \
  "http://www.apple.com/DTDs/PropertyList-1.0.dtd";>
  <dict>
        <key>Disabled</key>
        <false/>
        <key>UserName</key>
        <string>root</string>
        <key>GroupName</key>
        <string>wheel</string>
        <key>Label</key>
        <string>com.openlinksw.vos6</string>
        <key>Program</key>
        <string>/usr/local/virtuoso-opensource/bin/virtuoso-t</string>
        <key>ProgramArguments</key>
        <array>
                <string>virtuoso-t</string>
                <string>-f</string>
        </array>
        <key>KeepAlive</key>
        <dict>
                <key>SuccessfulExit</key>
                <false/>
        </dict>
        <key>WorkingDirectory</key>
        <string>/usr/local/virtuoso-opensource/database</string>
  </dict>


Note that since you are installing vos in /usr/local/virtuoso- 
opensource, i recommend you use:

	./configure --prefix=/usr/local/virtuoso-opensource --with- 
layout=openlink ....


this will create a much easier directory structure like:

        /usr/local/virtuoso-opensource
                /bin
                /lib
                /hosting
                /database

rather than the Linux File System Layout that a default installation  
would use.
