We are moving the DataStage installation from one Solaris machine to another one.
Of course we could re-install the DataStage software. But a simple unmount of all concerned filesystems and remount on the new Solaris server seems also be a correct option. All the code, configurations, etc is located in file systems.
The only question left is if there is any DataStage information, which is located in the UNIX filesystems. I only found the symbolic links below.
Please comment wether the filesystem unmount/mount approach is a viable option? And are the links below, the only DataStage objects in the UNIX directories (/, /usr, /etc, /var, ...) that need to be recreated by hand?
lrwxrwxrwx 1 root other 63 Feb 13 2006 /etc/rc2.d/S99ds.rc -> /export/home/rdcdsadm/Ascential/DataStage/DSEngine/sample/ds.rc
lrwxrwxrwx 1 root other 63 Feb 13 2006 /etc/rc0.d/K99ds.rc -> /export/home/rdcdsadm/Ascential/DataStage/DSEngine/sample/ds.rc

Thanks in advance for all input,

You may have a file called /.dshome.
I don't know whether the unmount/mount technique will work. DataStage internally does not may use of inodes except in the lock tables at run time or when a client is actually connected, so that's a positive for you. The main thing is that everything must be in exactly the same "location" (pathname) on the new server.

Roy,
indeed. I forgot the /.dshome, which I also will need to copy by hand.
But the version of DS is 7.5.1A. If I'm well informed, it is the first version which officially supports multiple DS servers on a single UNIX box. This is our case. As /.dshome can only point to one of the multiple servers, I deduce that DataStage itself has no need for this file. (Otherwise the second server instance wouldn't be able to work properly) The only dependency on this file would be through customer built scripts and profiles, which may source this file. Would you agree?
Thanks,
Wim
