Hi Larry,
On sun you have /var/opt/oracle. it hosts the files oratab and oraInst.loc. copy both files. In oraInst.loc you will find the directoryname wher orainst stores its Inventory, something like /opt/oracle/oraInventory. Copy this dir as well. BTW, start oui and choose 'show installed products'. It will show you what has been installed.

Furthermore, be sure that you create the OS-user oracle and groups dba and oinstall with the same id's as the production system.

You can copy the whole software tree (e.g. /opt/oracle/...) including admin directories. Under 8i this works fine, from 9i onwards it is getting more complicated due to all kind of server-dependent enties in oraInventory and in the software directories, especially when using things as iAS and Grid Control.

For the database: you didn't tell wether it's Standard Edition or Enterprise Edition. If it is Enterprise, you can download Data Guard for Solaris for Oracle 8i from
http://otn.oracle.com/software/deploy/availability/index.html. The documentation of 8i Data Guard is at
http://otn.oracle.com/docs/deploy/availability/pdf/A95293_01.pdf.

Dat Guard has quite some advantages over 'classic' standby. It will e.g. automatically add datafiles on the standby, and also resolve gaps in the archives if the network connection has been down for a while. It is not that difficult to implement.

HTH, Carel-Jan
