Hi,

Is it possible to have say

Companies - 001,002,003 and 004 in DB2 Database in AIX Sever (Server1)

and

Companies - 005,006,007 in Oracle Database in HP -UX Server (Server2)

This done for the same Baan Instance again in a different HP-UX Server (Server3)

This is defiitely possible . Keep in mind following.

1. Ensure that servers connects using gigabit lan cards and the switch if any used is gigabit .
2. Minimize or still better eliminate transactions across companies which spans across databases . Tehcnically baan db drivers do take care off transactions , but across os different db it introduces high complexity and with possibility on unpredictable results at times .
3. As a corollary to point 2 above , do not have table sharing between companies spanning across databases .
4. Last but not the least which database 0 company will belong . If u allocate 0 to any 1 db instance , then u will always have primary dependency for the db of 0 company. So I would recommend u may use bisam for 0 company on server 3 (which is built in porting set and all u need is to have the same in validation keys) . This will ensure continuity for all companies irrespective of the availability or other wise of other db. Further bisam is capable enough to handle low volume low growth company like 0 (appx 1-2 GB max ) and the recovery also can be faster .
