Installating 7.2.2.4 Sunday; General Questions

We are going to install our 7.2.2.4 Oracle on Sunday. Some questions I want to straighten out before we go ahead with it. (We have never had ORACLE nor installed it!)

Installing on HP9000; HP-UX 9.04; 256MB RAM;

 	350MB space on 1 disk: /users
	244MB space on another disk:  /oracleDB
	8-concurrent user system (to be expanded to 16, then 40 in 
	next 3 years).
	
	Client-Based Installation:  Server will only have database,
	tools (Developer/Discoverer 2000) will be on clients (PCs).

System Administer wants to install on:	  /users/orahome
Want to put database on:		  /oracleDB

I am hoping to Install it under the "BASE" installation to be able to update/migrate WITHOUT uninstalling the current version when future versions come in.

1.  	What is Distributed Space?   Is that the space for the server 
	software?

2.	What exactly is an sid?  What should I be setting the 
	environment variable ORACLE_SID to?

3.	How would I get the installer to follow my BASE installation
	structure?  How do I tell it that the database will be on
	disk vg00 while the server software is on disk vg01?

	If my directory structure is as shown above, do I have to LINK
	the db_name1 directory to /users/oracleDB (on the other disk)?

	Also, how do I distribute the LOG and REDO files across separate
	disks (if I wanted to)?

4.	What is the TNS Listener?  Do I need it? (I don't think I do!!)

5.	NETWORK Software:

	I know I have to install SQL*Net V2 with the TCP/IP Adapter, but
	WHY is TNS Listener listed with it?

	What is the MultiProtocol Interchange?

	What's the Names Server?

6.	Exactly what are the software components that I would NEED to 
	install?  If my tools are on the PCs, then some of these would be
	installed only on the PC, some on server, and some on both - I would
	think!



	- SQL*Net

	- SQL*Plus

	- SQL*DBA

	- SQL*Loader  (what does this do?)

	- Export

	- Import      (isn't this SQL*Loader)

	- Server Manager

	- Migration Tools


	- EASY*SQL 	(What the heck is this?!)





	- How is the FORMSGENERATOR different from FORMS?



7.	What is a default small database size? 

	(Oracle consultant told me 100MB, but ICG book says 21MB)

8.	I am not installing the Online Documentation, but I will 
	the Online Help.  This is mainly because Help takes only
	4.9 MB (according to ICG).  IS THIS TRUE?

YOU WILL BE REGARDED AS A GOD IF YOU ARE SO KIND TO RESPOND! Thanks in advance - Mir Received on Thu Feb 01 1996 - 00:00:00 CET
