-====== Setup of Database Server ======
-====Teaching - Understanding DB2====
-<code>
-The database server is not accessible by students or faculty directly
-Any connection to the database will occur from the client's instance
-As of September 2012, we are running DB2 -Express-C Version 10.1
-This is a freely available version for universities.
-You need to register with IBM's Academic Initiative Alliance for valid downloads
-The client's connection can be accessed from any host users can login into with a valid
-unix login.
-Entering db2 from any linux desktop in the department will
-allow you to access db2 eg:
-   gemini 316 % db2 connect to c3421a
-   Database Connection Information
- Database server        = DB2/LINUXX8664 10.1.0
- SQL authorization ID   = SEELA
- Local database alias   = C3421A
-For Teaching purposes , databases are created by the administrator once a semester
-and always takes the course number and session. At the end of each semester, it is
-dropped .
-</code>
-**Faculty members who are teaching the course must remember to request the
-creation of the database for that particular semester.
-**
-====Teaching with a Database====
-In order to create a database for the current semester
-First drop the previous term. It's always good to consult with the teaching
-faculty that they have already submitted their marks
-If not DO NOT DROP
-Then proceed to dropping the database if you have permission
-   * On the client host (red as an example and using the client id db2leduc)
-     Become user db2leduc
-     db2 "uncatalog database c3421a"
-     If successful and you issue the following command , the database should not
-     exist on the list
-     db2 list database directory
-   * On the DB Server (gold)
-     as the instance owner
-     db2 drop database c3421a
-   * Now create the database for the winter semester
-     db2 create database c3421m
-         The CREATE DATABASE command completed successfully.
-   * Back on the client host
-     db2cli
-     db2 catalog database c3421m as c3421m at node gold
-         The CATALOG DATABASE command completed successfully.
-   *  make the database available to all users
-      On the DB server, connect with the instance ID and do the following
-             $db2 connect to database name
-       $db2 "revoke connect , createtab, bindadd on database from public"
-       $db2 "grant connect , createtab, bindadd on database to group faculty"
-       $db2 "grant connect , createtab, bindadd on database to group ugrad"
-       $db2 "grant connect,createtab,bindadd on database to group grad"
-   * Test the connection from any client host in the lab (all linux machines in the department)
-      From any host in prism
-       jun04 > db2
-               db2=> connect to c3421a
-                     list tables
-                ....
