20010905: [Fwd: Re: 20010904: LDM startup, location of data]

Patrick,

Use the LD_LIBRARY_PATH environmental variable in the LDM environment
to specify the location of the shareable libraries- wherever
you decide to keep them on your system.

Place the LD_LIBRARY_PATH definition in the shell configuration file 
(eg .cshrc for the csh environment) so that whenever you start the LDM,
or have the LDM start on boot, the path to the shareable libraries is found.

>>
>> /etc/init.d contains initialization and termination scripts for

>> files in the rc?.d directories.
>>
>> File names in rc?.d directories are of the form [SK]nn<init.d filename>
>> where 'S' means start this job, 'K' means kill this job, and 'nn' is

>> scripts in /etc/rc[S0-6].d that are prefixed with 'K' followed by those
>> scripts prefixed with 'S'.  When executing each script in one of the
>> /etc/rc[S0-6] directories, the /sbin/rc[S0-6] script passes a single
>> argument.  It passes the argument 'stop' for scripts prefixed with 'K'

>>         that should not be running in state 2.  The filenames are

>>         in alpha-numeric order when the system enters init state 2.

>>
>>         2. Also in the rc2.d directory are files used to start processes
>>         that should be running in state 2.  As in the step above, each
>> 'S'
>>         file is executed.
>>
>>         Example:
>>
>>                 Assume the file /etc/netdaemon is a script that will
>>                 initiate networking daemons when given the argument
>>                 'start', and will terminate the daemons if given the
>>                 argument 'stop'.  It is linked to
>> /etc/rc2.d/S68netdaemon,
>>                 and to /etc/rc0.d/K67netdaemon.  The file is executed by
>>                 '/etc/rc2.d/S68netdaemon start' when init state 2 is
>>                 entered and by '/etc/rc0.d/S67netdaemon stop' when
