1.) Why is it setup so that it is easier to change domain name (whenever start an instance DOMAIN_NAME) than database name ( Hard to change because it is recorded in control file) ?
2.) I have 3 disk and one disk array (RAID). Oracle has recommended 7 disk configuration
(DBA manual from Oracle press). And temporary tablespaces for each application and
redo log files(online and archived) can be put on raid 1 but not RAID 5. ( We used to plan
for RAID 5 !!!!!) Any example or recommendation on the configurations ?
3.) Production database, development database, standby database, distributed database..
Naming convention example ? ( Oracle owner: Oracle_prod, Oracle_dev, DBA01P, DBA01D.?)
Also have to consider applications so DBA01P_APP1, DBA01P_APP2, DBA01D_APP1, DBA02D_APP2?) Good idea to have database account and UNIX account one-to-one relationship ?
