Oracle Installation Summary under Linux

Oracle claims to install the Oracle9i database under Linux at least 512MB of memory and at least 1GB or twice times the memory size of the swap space, for the system memory is greater than 2GB of servers, swap space can be between 2gb-4gb.
If you are trying to try oracle9i on a normal PC with only 256M of memory, you can run the Oracle database normally if you have a 1GB swap space allocated.

To check the memory space, log on to Linux, and execute the following commands on the command line (Bash environment): grep memtotal/proc/meminfo

To check the swap space, execute the following command at the command line: grep swaptotal/proc/meminfo

1. Extract. cpio file #cpio-IDVM < Lnx_920_disk1.cpio
#cpio-IDVM < Lnx_920_disk2.cpio
#cpio-IDVM < Lnx_920_disk3.cpio

Generates DISK1 and DISK2,DISK3 three directories under the current directory.

#rpm-IVH *.i586.rpm--nodeps--force

3. Establish user and group #groupadd DBA
#mkdir/opt/oraclehome
#adduser-U 499-d/opt/oraclehome/-G DBA Oracle

Note:-U can be 1-500 (System user)-G added to the private group DBA #chown oracle.dba/opt/oraclehome/
#mkdir/opt/oraclehome/ora9i
