I know there are Oracle DBs installed on my UNIX server. Is there any way to get those DB names? I'm using Sun OS.
You can also try ps -ef | grep -i pmon. Each running pmon process would be for one DB and base on the pmon name your database would be ora_pmon_<db sid>. There could be additional DBs that are not running currently but this would give you the active running database on a Sun box. Also check the /var/opt/oracle/oratab as mention above for the listing of the DBs if the DB admin is keeping the DB properly listed in oratab.
cat /etc/oratab|grep -v "^#"|grep -v "N$"|cut -f1 -d: -s

How can I backup my sybase tables and restore using command line?
please help me with the command using bcp
I have tried using sybase central GUI
Thanks.
Since you didn't specify whether you are running on Windows or Unix I'll try to cover both.
Unix
bcp is located in $SYBASE/$SYBASE_OCS/bin/
Windows
bcp is located in %SYBASE%\%SYBASE_OCS%\bin
Export
bcp DB_NAME..TABLE_NAME out TABLE_NAME.bcp -Sservername -Uusername -Ppassword -[c or n]
Choose either -c or -n depending if you want the file to be human readable or not. I recommend using -n unless you have a compelling need to use -c TABLE_NAME.bcp can be any filename, with any extension.
Import
$SYBASE/$SYBASE_OCS/bin/bcp DB_NAME..TABLE_NAME in TABLE_NAME.bcp -Sservername -Uusername -Ppassword -[c or n]
There are many more options and flags available, but these are the basics to get it to work.
More information abou the bcp utility can be found here:

In SqlServer Management Studio, if we click on data database there is menu task > export data.
This help me to export this database to another server.
However, I need to run this wizard to complete this task and need to specify source and destination sever information every time that I want to use it.
I think it would be convenient if I could use command line to do the same task and write batch file to automate it.
Please could you help me give some suggestion or introduce me a command line program that can do this task since I googled search but not found any useful information.
Thank you so much.
U can use BCP Utility
BCP Out
BCP server.schema.TableName out c:\TableName.txt -c -t -T –SServerName -UUsername -Password
BCP In
BCP server.schema.TableName In c:\TableName.txt -c -t -T –SServerName -UUsername -Password
The 1st statement is to export the data to a csv file and BCP IN is used to import the data from csv file to Destination table
Here
-T stands for Trusted connection and -t represents field delimeter
You can write these BCP commands in batch file
Or you can create a simple ssis package for exporting the data

I have a DB server and it has a table of 90 GB. Now I want to take a back up of that table.
But DB is almost full and I cannot take back up into the same server.
Is there any way of taking backup using mysqldump -u username -ppassword dbname tablename > different_server_location
I used to do it on same server these days.
example:
mysqldump -u username -ppassword dbname tablename > /tmp/file_name
Since there is NO space available on DB server, how can I take backup of a table which is 90 GB!
and can I take backup of a file in few pieces. I mean 10 GB at once and so on ?
Why don't you dump from another server in same network like:
mysqldump --host=myserver -u backup mydb > test.sql

I am working on Ubuntu 12.04. I need to set up a database with the help of something like SQL server. Or is there anyway to set up a database on our own?
I need to practice using SQL, now I am working on "Informix AIX" systems to practice. I need this set up to be done asap.
I would recommend installing MySQl as it is open source and free to use for educational purposes. If you want to redistribute it for commercial purposes it requires a license (thought I would throw that in just in case).
It is pretty simple to get installed on Ubuntu, simply type in sudo apt-get install mysql-server in a terminal and it will do the rest for you. It will prompt you to set a password for the database, but once the installation is complete the server should start up automatically and be ready to start using.
If you have any questions, a good tutorial to look at can be found at: https://help.ubuntu.com/12.04/serverguide/mysql.html
To access the database from the command line simply use: mysql -u <username> -p (don't give an argument to the -p switch; just hit enter and make sure -p is the last word on the command line). That command will prompt you to enter in your password. The password should be entered password interactively because the command history is saved in plain text and anyone can thus press the up arrow key to find your password if you entered it in the command line.
Hope that helps,
Trevor
MySQL is popular, but I prefer PostgreSQL. It has more complete support for SQL standards and ACID transactions. But it does not have quite the performance of MySQL for read actions.

I am working remotely on a Windows Server via Remote Desktop Connection and some process has hung the server. I looked up how to bring up the Task Manager remote (equivalent of locally doing CTRL+ALT+DEL) and I found CTRL+ALT+END and it doesn't seem to work.
I tried logging off and logging back on and the system is still up (tried earlier seeing the properties of My Comptuer, FYI).
Does anyone know how I can escape this 'hindrance' and star fresh?!?
Start the task manager with e.g right-clicking in the bottom right or just start it manually with taskmgr in "execute"
