Install guide

Notes on .lmkrc: you will need to copy the .lmkrc into the home directory of every user
that wishes to run lmksh interactively:
prompt> cp $OWHOME/WebApps/templates/wow.lmkrc $HOME/.lmkrc
Add or uncomment the commands OWSetup in .lmkrc so you do not need to type these
during every interactive session. Add or uncomment SourceAllProcs to load all
available commands.
The lmksh Commands
There are three classes of commands:
Tcl built-in commands: This is the core Tcl language. See the Tcl man pages or html
help at $OWHOME/WebApps/tcltk/htmldocs/tcltk.html for information on built-in
commands. To access the man pages:
prompt> source $OWHOME/WebApps/templates/wow.login
prompt> man <cmd>
Extended commands: These are added to lmksh to provide scripted access to devkit
functions. The extended commands are usually low-level with little error trapping. Most
begin with sdl_ (SeisWorks), ow_ (OpenWorks), sil_ (MFD), zgf_ (ZGF), sgy_
(SEGY) and gen_ (LAS and others). To see the arguments for an extended command,
type the command name, e.g.:
lmksh{7}% ow_poslog
Procedures: These are additional ‘wrappers’ to the extended commands, including more
robust error trapping and other business logic to make the low-level commands more
useful. To see the arguments for any procedure, e.g.:
lmksh{8}% info args GetPoslog
OpenWorks database access procedures usually start with a lowercase letter to denote
that they require an Oracle database connection to be established first, e.g.:
prompt> rlmksh
lmksh{9}% set lda [OWoralogon]
lmksh{10}% getWellLists TESTDATA
lmksh{11}% oralogoff $lda
Exposing lmksh Commands
It is sometimes more convenient to run lmksh procedures through a regular Bourne- or C-
shell. A wrapper script is provided in $OWHOME/WebApps/bin for this purpose. To
‘expose’ any lmksh procedure on the command line, create a link as illustrated below:
prompt> cd $OWHOME/WebApps/bin
prompt> ln –s wlmksh <proc>
The procedure can then be run on the command line, with any required parameters
passed through to the underlying lmksh.
Warning
WOW and CDA are largely read-only applications. But the underlying lmksh has
additional destructive options, e.g. the ability to create, rename and delete
SeisWorks horizons. Use of these options is entirely at your own risk, and you
should always ensure you have a current backup before proceeding.
