Summary of Oracle Installation (Linux) by freet15 [article from:] Oracle Installation (Linux) by lanf, source: Author: Oracle Installation in freet15 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 Data 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. Execute the following command in the command line: grep swaptotal/proc/meminfo 1. decompress. cpio file # cpio-idvm <lnx_920_disk1.cpio # cpio-idvm <lnx_920_disk2.cpio # cpio-idvm <lnx_920_disk3.cpio generates disk1, disk2, and disk3 in the current directory. 2. patch unzip into lerpm.zip # rpm-IVH *. i586.rpm -- nodeps -- force 3. create a 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.

Note: A new user's language environment is added in the system (every time a user is added, it is copied to its home directory for generation. i18n) 2. error during installation: the first few errors are indicated by the error message. Only the last/opt/oraclhome/Oracle9i/CTX/lib/file has an error, modify the/opt/oraclhome/Oracle9i/CTX/lib/env_ctx.mk file to add a record $ (ldlibflag) dL 3 in the inso_link = line. oracle User Shell problems # userdel Oracle # adduser-u 499-D/opt/oraclehome/-g dba Oracle tips: # hdparm-T/dev/hda view hard disk read/write speed, if it is only about 2 MB, run # hdparm-D 1/dev/hda to enable the DMA function and add it to/etc/rc. local file.
