I am sure this has been covered many time before but here goes
First
I am in the midst of deploying a large complex program
Development Server Solaris 8 IDL 6.1 Oracle DB Jdeveloper
Deploying to
Server1 Oracle DB Solaris 10
Server2 Solaris 9 IDL 6.2--Web based env Web Server OC4J pages and
xslt's built in jdeveloper
All IDL Programs are non-interactive and produce png files for use in a
browser across the network--called from java pages and accessing files
produced by the DB.
First problem encountered and fixed. we got a zlib mit_magic_cookie
error and detiremined this was a unix problem resolving the xserver
address. we found a program Xvfb and set the xwindow display to :1.0
(setenv DISPLAY :1.0) and zlib was solved. typing hosts + at the term
screen fixed the cookie error
This all sounds and is very ugly and confusing....
That being said 50% of the programs (coded by many people) work perfect
on server2 all work on the development server. All programs run at the
command prompt and produce results (png). Half the idl programs
produce black pictures and if you tweak the color table you can see it
is also producing kind of a triple picture.
We have narrowed it (I think) to being an issue where we need to use a
z-buffer this is how we got the black pictures. We are currently using
tvlct and setting a custom color table r,g,b.
I have noticed some differences in the display while in IDL on the
developement server and the deployment server. one running 24 bit
color and one running 8 bit. the resolution is different also.
any help on this will be greatly appreciated.........
