DB2 筆記 - uninstall

把這幾天在AIX遇到的問題整理出來，要裝DB2前請先注意這些事
(雖然已經裝很多次，每次都會遇到新問題，趕快抄筆記呀)

1.每個槽都擴充到最大，只要有空間，全都擴充到10G吧～
/ (root)/usr /var /tmp /home
2.該裝的fileset都要裝喔，DB2才能ready
3-1.如果不幸要倒帶回去，先切成磁帶開機，省時又方便喔
bootlist -m normal rmt0
3-2.如果真的很不想倒帶回去，先手動移掉DB2吧
Tips
1. Drop DB2 instance
/opt/IBM/db2/V9.1/instance/db2idrop -f db2inst1
2. Uninstall previous db2
Drop the DAS server as root:
bash-3.00# pwd
/opt/IBM/db2/V9.1/instance
bash-3.00# ./dasdrop
SQL4410W The DB2 Administration Server is not active.
DBI1070I Program dasdrop completed successfully.

Then db2_deinstall UDB:
bash-3.00# pwd
/opt/IBM/db2/V9.1/install
bash-3.00# ./db2_deinstall -a
DBI1016I Program db2_deinstall is performing uninstallation.
Please wait.
The execution completed successfully.
3. Run db2 V9.1 install, db2_install will install at console (non-GUI).
4. After install, create an instance
/opt/IBM/db2/V9.1/instance/db2icrt -u db2fenc1 db2inst1

bash-3.00# ./db2icrt -u db2fenc1 db2inst1
DBI1070I Program db2icrt completed successfully.
