Hi osf-managers,
For the following posting:

>> -r /usr/local/tecplot/tlm/license.res

Most repsonses were similar, and a summary follows:
1) - Put the tecplot script above into '/sbin/init.d' and call it tecplot
- in '/sbin/rc3.d' have a file S96tecplot as symbolic link to
'/sbin/init.d/tecplot'
- This starts up the licence manager once.
2) - Create a continuous loop in the above script to check if the 'tlmd' daemon
dies and then restart it.
3) - Place a 'wait' statement after starting 'tlmd' in the above script.
- NOTE: This does not work, though it seems to be a logical solution.
The option I took was (1). Looking at the responses I think I went into
overkill wanting the 'start_license' to be rerun when the daemon dies.
A daemon is a daemon and probably will very rarely die, so option (1)
was a good choice. Option (2) will certaintly work, when if it ever does
die. I tried option (3) and the same problem occures. Though I can not see
why it wouldn't work.
Again thanks to all, sorry for the long summary for a trivial solution &
happy computing.....
