HOW TO SHUTDOWN DATABASE ORACLE

How To Startup Oracle Database

1. Login to the system with oracle username

Typical oracle installation will have oracle as username and dba as group. On Linux, do su to oracle as shown below.

$ su - oracle
2. Connect to oracle sysdba

Make sure ORACLE_SID and ORACLE_HOME are set properly as shown below.

$ env | grep ORA
ORACLE_SID=DEVDB
ORACLE_HOME=/u01/app/oracle/product/10.2.0

You can connect using either “/ as sysdba” or an oracle account that has DBA privilege.

$ sqlplus '/ as sysdba'
SQL*Plus: Release 10.2.0.3.0 - Production on Sun Jan 18 11:11:28 2009
Copyright (c) 1982, 2006, Oracle. All Rights Reserved.

Connected to:
Oracle Database 10g Enterprise Edition Release 10.2.0.3.0 - Production
With the Partitioning and Data Mining options
SQL>
3. Start Oracle Database

The default SPFILE (server parameter file) is located under $ORACLE_HOME/dbs. Oracle will use this SPFILE during startup, if you don’t specify PFILE.

Oracle will look for the parameter file in the following order under $ORACLE_HOME/dbs. If any one of them exist, it will use that particular parameter file.

spfile$ORACLE_SID.ora
spfile.ora
init$ORACLE_SID.ora

Type “startup” at the SQL command prompt to startup the database as shown below.

SQL> startup
ORACLE instance started.

Total System Global Area 812529152 bytes
Fixed Size 2264280 bytes
Variable Size 960781800 bytes
Database Buffers 54654432 bytes
Redo Buffers 3498640 bytes
Database mounted.
Database opened.
SQL>

If you want to startup Oracle with PFILE, pass it as a parameter as shown below.

SQL> STARTUP PFILE=/u01/app/oracle/product/10.2.0/dbs/init.ora
How To Shutdown Oracle Database

Following three methods are available to shutdown the oracle database:

Normal Shutdown
Shutdown Immediate
Shutdown Abort
1. Normal Shutdown

During normal shutdown, before the oracle database is shut down, oracle will wait for all active users to disconnect their sessions. As the parameter name (normal) suggest, use this option to shutdown the database under normal conditions.

SQL> shutdown
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL>
2. Shutdown Immediate

During immediate shutdown, before the oracle database is shut down, oracle will rollback active transaction and disconnect all active users. Use this option when there is a problem with your database and you don’t have enough time to request users to log-off.

SQL> shutdown immediate;
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL>
3. Shutdown Abort

During shutdown abort, before the oracle database is shutdown, all user sessions will be terminated immediately. Uncomitted transactions will not be rolled back. Use this option only during emergency situations when the “shutdown” and “shutdown immediate” doesn’t work.

$ sqlplus '/ as sysdba'
SQL*Plus: Release 10.2.0.3.0 - Production on Sun Jan 18 11:11:33 2009
Copyright (c) 1982, 2006, Oracle. All Rights Reserved.
Connected to an idle instance.

SQL> shutdown abort
ORACLE instance shut down.

THC-SSL-DOS The Hackers Choice Released

SSL or secure socket layer seems to be more secure but what keep in mind there is no security in this world there is only an opportunity, as discussed how to crack SSL on backtrack machine. Now the question how to measure the performance of SSL certificate the problem has been solved because THC just release a tool called THC-SSL-DOS the hacker choice. The hacker choice is a group of German hackers and THC-hydra is good password cracker that has also released by this team.

What is THC-SSL-DOS ?

THC-SSL-DOS is a tool to verify the performance of SSL. Establishing a secure SSL connection requires 15x more processing power on the server than on the client. THC-SSL-DOS exploits this asymmetric property by overloading the server and knocking it off the Internet.
This problem affects all SSL implementations today. The vendors are aware of this problem since 2003 and the topic has been widely discussed. This attack further exploits the SSL secure Renegotiation feature to trigger thousands of renegotiations via single TCP connection.


http://www.blogger.com/img/blank.gifhttp://www.blogger.com/img/blank.gif
“We are hoping that the fishy security in SSL does not go unnoticed. The inhttp://www.blogger.com/img/blank.gifdustry should step in to fix the problem so that citizens are safe and secure again. SSL is using an aging method ohttp://www.blogger.com/img/blank.giff protecting private data which is complex, unnecessary and not fit for the 21st century.”, Says a THC member, referring to 3 major vulnerabilities disclosed in SSL over the past 3 years.

Windows binary:thc-ssl-dos-1.4-win-bin.zip
Unix Source : thc-ssl-dos-1.4.tar.gz

Use "./configure; make all install" to build.
Usage:

./thc-ssl-dos 127.3.133.7 443
Handshakes 0 [0.00 h/s], 0 Conn, 0 Err
Secure Renegotiation support: yes
Handshakes 0 [0.00 h/s], 97 Conn, 0 Err
Handshakes 68 [67.39 h/s], 97 Conn, 0 Err
Handshakes 148 [79.91 h/s], 97 Conn, 0 Err
Handshakes 228 [80.32 h/s], 100 Conn, 0 Err
Handshakes 308 [80.62 h/s], 100 Conn, 0 Err
Handshakes 390 [81.10 h/s], 100 Conn, 0 Err
Handshakes 470 [80.24 h/s], 100 Conn, 0 Err


Tips & Tricks for whitehats
1. The average server can do 300 handshakes per second. This would require 10-25% of your laptops CPU.
2. Use multiple hosts (SSL-DOS) if an SSL Accelerator is used.
3. Be smart in target acquisition: The HTTPS Port (443) is not always the best choice. Other SSL enabled ports are more unlikely to use an SSL Accelerator (like the POP3S, SMTPS, ... or the secure database port).

Kismet – Wireless Network Hacking, Sniffing & Monitoring

For some reason I’ve never posted about Kismet, and I don’t like to assume everyone knows everything. So for those who may not have heard of it, here’s Kismet.

Kismet is one of foundation tools Wireless Hacking, it’s very mature and does what it’s supposed to do.

Kismet is an 802.11 layer2 wireless network detector, sniffer, and intrusion detection system. Kismet will work with any wireless card which supports raw monitoring (rfmon) mode, and can sniff 802.11b, 802.11a, and 802.11g traffic.

Kismet identifies networks by passively collecting packets and detecting standard named networks, detecting (and given time, decloaking) hidden networks, and infering the presence of nonbeaconing networks via data traffic.

Features

Ethereal/Tcpdump compatible data logging
Airsnort compatible weak-iv packet logging
Network IP range detection
Built-in channel hopping and multicard split channel hopping
Hidden network SSID decloaking
Graphical mapping of networks
Client/Server architecture allows multiple clients to view a single
Kismet server simultaneously
Manufacturer and model identification of access points and clients
Detection of known default access point configurations
Runtime decoding of WEP packets for known networks
Named pipe output for integration with other tools, such as a layer3 IDS like Snort
Multiplexing of multiple simultaneous capture sources on a single Kismet ihttp://www.blogger.com/img/blank.gifnstance

how to crack wifi WPA /PSK2 is easy

k untuk crack wifi WPA/PSK2 leceh sikit sebab nak kena ada orang access wifi tu dulu baru leh kita inject.cara die sama macam WEP p ada button lain kene click

mari kita tengok



1. Just select WPA/WPA2 and click scan.
2. Select the wifi that have client and click the dictionary attack to browse to your dictionary password list.
3. Click lauch to attack. If password still not found after the run out the dictionary list, you have to prepare a bigger dictionary list.

how to crack wifi WEP/WPA is easy

hehehe..

now i want introduce how to crack wifi WEP/WPA very easy used BEINI 0S
1. Insert CD to you CD Rom, restart your computer and boot the CD Rom (just like when you format computer to install windows, boot the CD).
You may need to change your boot order to CDROM first instead of Harddisk. It normally change change in bios setup during you start computer by press F2, F10, ESC depending your computer.
** If you don't know how to do this, kindly consult your friend/computer technician with basic computer knowledge.
Or go to www.google.com and search for how to "boot from CD ROM drive".

2. After boot successful, you will be bring to below screen. Click the Minidwep-gtk to start the program.
A windows will prompt out, just click ok.




3. When below windows prompt out, just click ok.



4. Click the Minipwep-gtk to start the program. Then click scan to scan the available wireless.



5. Select the wireless with client, and click the launch to start cracking process.



Note: the router that you want to hack must be using (have data transfer), the higher data transfer, the faster the cracking process.
If you notice that IVS value is not running, or running very very slow after few minutes, it means that there is no data transfer on the router. You may look for other time (when the router is using) to test again.

6. Below showing the IVS is running and increasing... Normally IVS Reach value around 30000 to 50000, the password will be found.





7. Below shown successful case with password shown. Copy down the password and close the software. Then logout and shutdown the machine.



hehe ni tuk WEP

g0d mod Win 7

kat sini nak share satu benda..

create satu folder
pastu rename kan folder tu ni God-Mode.{ED7BA470-8E54-465E-825C-99712043E01C}
pastu bukak folder tu...

hehe

selamat mencuba

Resolving ORACLE ERROR:ORA-28000: the account is locked

After installation of Oracle10g, there was a problem ..couldnt login using SQL+. None of the accounts(scott/tiger) worked . At last a quick web search gave the solution . Here is what it is:

example used name oracle is "scott"

From your command prompt, type
sqlplus "/ as sysdba"

Once logged in as SYSDBA, you need to unlock the SCOTT account
SQL> alter user scott account unlock;
SQL> grant connect, resource to scott;
