Notes for installing Oracle databases in Linux

Oracle claims that the installation of the Oracle9i database in Linux requires at least MB of memory and at least 1 GB or two times of memory swap space. For servers with a system memory larger than 2 GB, the swap space can be between 2 gb-4gb.

If you want to try Oracle9i on a general PC with only MB of memory, you can run the Oracle database normally when 1 GB of swap space is allocated.

To check the memory space, log on to Linux and run the following command in the command line mode (bash environment): grep MemTotal/proc/meminfo

To check the swap space, run the following command on the command line: grep SwapTotal/proc/meminfo

1. decompress the. cpio file # cpio-idvm <lnx_920_disk1.cpio

# Cpio-idvm <lnx_920_disk2.cpio

# Cpio-idvm <lnx_920_disk3.cpio

Generate three directories: Disk1, Disk2, and Disk3 under the current directory.

2. Patch unzip into lerpm.zip

# Rpm-ivh *. i586.rpm -- nodeps -- force

3. Create users and groups # groupadd dba

# Mkdir/opt/OracleHome

# Adduser-u 499-d/opt/OracleHome/-g dba oracle

Note:-u can be 1-500 (system user)-g after being added to the private group dba # chown oracle. dba/opt/OracleHome/

# Mkdir/opt/OracleHome/Ora9i

# Chown oracle. dba/opt/OracleHome/Ora9i

# Touch/etc/rac_on

# Mkdir/opt/tmp

# Chmod 1777/opt/tmp

# Cp oracle. bashrc/opt/OraclHome/. bashrc
