What development tools to use for oracle databases on Linux systems! Urgent!!

If it is an oracle user password of the operating system, change it directly as root. passwd oracle, enter a new password;

If it is an oracle database user, such as the password of user1. You can log in to the database with a user with sysdba permissions, such as SQLPplus'/as sysdba'Enter alter user user1 identified by new password at the SQL prompt;

Can you add me, please? I would like to ask you about EBS installation. I, thank you. Or do you have any relevant information, can you send me a copy, please.

First su to the oracle user.

sqlplus "/ as sysdba"

sql> startup

to start the database.

exit.

lsnrctl start (start listen) $sqlplus"/ as sysdba"

sql> shutdown

to stop the database.

exit.

lsnrctl stop

su - oracle

sqlplus "/as sysdba"

sql>startup starts the database.

sql>shutdown immediate Shut down the database sql>exit exit.

If you have the time to ask such a basic question, you might as well read a book.

1. su - oracle

2. sqlplus /nolog

3. conn /as sysdba

4. startup

Then start the listener (see the specific installation directory):

Go to OPT Oracle Product LSNRCTL START

Steps: 1. Log in as a user oracle;

2. Execution: $lsnrctl start

3. Execute: $sqlplus nolog

4. Execution: sql>conn as sysdba5, execution: sql>startup

6. Execute: sql>quit --exit.

The configuration of the server is very important. Procedures are also important, of course. Comparatively large data processing**. Preventing the server from becoming your bottleneck is a low-level mistake that is often made.

Hope mine can help you.

If the oracle service is not started, no matter what tools can not use oracle, if you can access the local area network or remote oracle database, you can not install oracle locally, you only need to install a client, the client is very small, the installation should be no problem.

If the computer configuration is low, you really can't install oracle! Otherwise, the consequences will be miserable.
