Table  2 – 1  summarizes the requirements for installing Oracle8i on your Linux
system. If your system fails to satisfy any listed requirement, perform the tasks
listed on page  2 - 4  as necessary to configure your system to meet these requirements.
Table  2 – 1  Linux System Configuration Summary
System Factor Requirement for Oracle8i
Linux Kernel Parameters:
Shared Memory SHMMAX  0 . 5 *(physical memory present in machine).
Check your system for additional restrictions.
This setting does not affect how much shared
memory is needed or used by Oracle8i or the
operating system. It is used only to indicate the
maximum allowable size. This setting also does
not impact operating system kernel resources.
SHMMIN  1 
SHMMNI  100 
SHMSEG  10 
Semaphores SEMMNI  100 
SEMMSL Set to  10  plus the largest PROCESSES parameter
of any Oracle database on the system.
The PROCESSES parameter can be found in
each initsid.ora file, located in the
$ORACLE_HOME/dbs directory. The default
value of PROCESSES for the preconfigured
database created by Oracle Database
Configuration Assistant is  50 .
SEMMNS Set to the sum of the PROCESSES parameter for
each Oracle database, adding the largest one
twice, then add an additional  10  for each
database. See  "Configuring the Linux Kernel for
Oracle8i"  on page  2 - 4  for an example of this
formula.
