I want to re-install system, how can I backup and recover?
hi, Because a hacker hackered our system, I have to re-install the solaris. How can I backup the oracle database? Just backup all the physical files? I am not a back up and recover expert.

Re: I want to re-install system, how can I backup and recover?
well if you are lucky and all the files are there, yes, backup the physical datafiles and when you bring the database up again, Oracle will recover. You MAY have to open the database resetlogs. Questions though: is the database still up? Can you shut it down cleanly (shutdown) and then do a cold backup of all the files? You are golden then. if the database is NOT up, do you run the database in archivelog or nonarchivelog mode. This will determine what you have to do to restart/recover the database. But no matter what take a backup of ALL the physical files on your system. This gives you a place to go back to if you do something incorrectly. Always good to have somewhere to go to start over.

Robert, If your Solaris box is truly compromised, a backup of all files, followed by a restore of all files, would give you the compromised box back. Aim higher. What is required is an install from original media, followed by a restore of only the absolutely necessary files - init.ora, control files, log files, data files. (from a cold shutdown). Don't restore by directory - restore by individual file. Leave everything else behind - on tape. Here is your starting point: http://www.cert.org/tech_tips/win-UNIX-system_compromise.html snip E.Recover from the intrusion 1.Install a clean version of your operating system Keep in mind that if a machine is compromised, anything on that system could have been modified, including the kernel, binaries, datafiles, running processes, and memory. In general, the only way to trust that a machine is free from backdoors and intruder modifications is to reinstall the operating system from the distribution media and install all of the security patches before connecting back to the network. Merely determining and fixing the vulnerability that was used to initially compromise this machine may not be enough. We encourage you to restore your system using known clean binaries. In order to put the machine into a known state, you should re-install the operating system using the original distribution media. /snip Now that you've gone through this, you may be tempted to use an intrusion detection system. Tripwire comes to mind - lots of other pieces of code for recording MD5 checksums of files. http://www.cert.org/tech_tips/intruder_detection_checklist.html Please don't reconnect the box to your network until it is completely patched. good luck - enjoy the learning experience.
