Install Oracle 11g R2 on Ubuntu

Ubuntu is not an official supported linux version from Oracle, so I still get some errors during the install process even with required configuration, anyway, it can work and what i'm doing here is try to setup an experiment environment, it's enough to me, any one who want to deploy Oracle in product mode should have supported linux platform like RedHat, OK, following is the steps i have to install it:

1. If you were in multihomed enviroment, set the ORACLE_HOSTNAME variable:
    export ORACLE_HOSTNAME=machine_name.domain_name

2. Create create OSDBA (dba) group, Oracle Inventory group (oinstall)  and a user "oracle" which has "dba" as its login group and oinstall as its 2nd group.

3. Modify /etc/sysctl.conf, set kernel parameter:

kernel.shmall = 2097152
kernel
.shmmax = 2147483648
kernel
.shmmni = 4096
kernel
.sem = 250 32000 100 128
fs
.file-max = 65536
net
.ipv4.ip_local_port_range = 1024 65000
net
.core.rmem_default = 1048576
net
.core.rmem_max = 1048576
net
.core.wmem_default = 262144
net
.core.wmem_max = 262144

4. Modify /etc/security/limits.conf to improve the "number of process" and "number of open file"  performance for oracle:
oracle              soft    nproc   2047
oracle              hard    nproc   
16384
oracle              soft    nofile  
1024
oracle              hard    nofile  
65536

5. Modify /etc/pam.d/login, add:
session    required     /lib/security/pam_limits.so
session    required     pam_limits
.so

6. Modify /etc/profile:
if [ $USER = "oracle" ]; then
        
if [ $SHELL = "/bin/ksh" ]; then
              ulimit 
-16384
              ulimit 
-65536
        
else
              ulimit 
-16384 -65536
        fi
fi

7. Change user to oracle if you haven't done it yet

8. Create base directory, for me it's "/app/oracle"

9. Export ORACLE_BASE, ORACLE_SID
export ORACLE_BASE=/app/oracle
export ORACLE_SID
=orcl

10.  If you're trying to install oracle with a X window:
DISPLAY=your.ip.address:0.0 ; export DISPLAY

11. run installer:
./runInstaller

12. Oracle should start, if the installer GUI cannot be start, check the error messages, most time it's because a wrong X window configuration, if you are running X window with Xming, just like me, please do make sure to check the "No Access Control" check box in the launch, otherwise, Xming will reject the connection.

13. Now the GUI shoudl open, like what you did in the Windows system, fullfill required value and click next, ingore all errors if there is any condition that is not match, click finish in the last step, it should start install process.

14. After install oracle, the installer GUI will ask you to run two .sh files, run it with a root role.

15. You can try to visit https://you.ip.address:1158/em to see is that OK for you.

16. How to start oracle:
export ORACLE_BASE=/app/oracle
export ORACLE_HOME
=/app/oracle/product/11.2.0/dbhome_1
export ORACLE_OWNR
=oracle
export ORACLE_SID
=orcl
export PATH
=$PATH:$ORACLE_HOME/bin


lsnrctl start

sqlplus 
/nolog
connect /as sysdba
startup
quit

emctl start dbconsole

How to connect Reliance Modem AC2726 on Linux Ubuntu 9.10

1. Type command: lsusb
Bus 002 Device 003: ID 19d2:fff5 ONDA Communication S.p.A.
2. Install "usb-modeswitch", then re-plugin modem again and input command "lsusb" again, you should get the following output
Bus 002 Device 003: ID 19d2:fff1 ONDA Communication S.p.A.
3. Notice in step #2, the product code has been changed from "fff5" to "fff1".
4. Install package "wvdial" which is used to dail up
5. Type command: "sudo modprobe usbserial vendor=0x19d2 product=0xfff1", don't forget the "sudo"
6. Type command: "sudo wvdialconf", again don't forget the "sudo", this will detect your modem
7. Modify file "/etc/wvdial.conf", following is what I have:

[Dialer Defaults]
Init1 
= ATZ
Init2 
= ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Modem Type 
= Analog Modem
ISDN 
= 0
New PPPD 
= 1
Phone 
= #777
Modem = /dev/ttyUSB0
Username 
= yourName
Password 
= yourPassword
Baud 
= 921600
Stupid Mode 
= 1
Tonline 
= 0

8. Repeat step #5 again and then if you with not bad luck type in command "sudo wvdial", you should connect in.
9. If bad luck with you, click right-upper corner, there is a connection configuration menu, you can create "Mobile Broadband" connection yourself here, don't forget input the phone number "#777" (for China Telcom) and your username password, after that click connect, this works for me.
10. Good luck with you.
11. BTW, if it still cannot work, try to re-plug in the modem.

Oracle Tips Part Two

1. It will not get data from DB when just open the cursor, data will be loaded as an ongoing basis.

2. SCN: System Change Number/System Commit Number

3. FLASH BACK AS OF SCN;

4. You can also flash back table: FLASHBACK TABLE SOME_TABLE TO SCN :SCN_NUM;

5. But before you do a flash back operation on a table, do make sure you have already enbale ROW MOVEMENT on that table.
