 ================ AIX ================
 [ Recommended Kernel Parameter Values ]

 fsize = -1
 data = -1
 rss = -1

 Maximum number of processes allowed per user
     Must be greater than the value set using the ALTIBASE XDB property MAX_CLIENT

 Size of the File System BufferCache
     Must be less than 20% of total memory

 AIO = Available

 AMO = AIX version 5.2 ML04 and above
              lru_file_repage=0
              strict_maxclient%=0
           = Versions prior to AIX version 5.2 ML04
               lru_file_repage=0

 [ How to modify kernel parameter values ]

 Edit /etc/security/limits file
 Set fsize, data and rss variables.

 Run 'smit'
  1) System Environments
      System Environments -> Change / Show Characteristics Of Operating System
      Change: 
          Maximum number of processes allowed per user
              Must be greater than the value set using the ALTIBASE XDB MAX_CLIENT
              property
          Size of the File System BufferCache
              Must be less than 20% of total memory.
  2) AIO 
      Device -> Asynchronous I/O -> Posix Asynchronous I/O 
      -> Configure Defined Asynchronous I/O
      Change: posix_aio0=Available

  3) AMO 
      Performance & Resource Scheduling -> Tuning Kernel & Network Parameters 
      -> Tuning Virtual Memory Manager, File System and Logical Volumes
      Manager Parameters ->
         + List All Characteristics of Current Parameters --- Check
         + Change / Show Current Parameters --- Current Changes
         + Change / Show Parameters for Next Boot --- Change upon Reboot

      When using AIX version 5.2 ML04 or above:
             Change: lru_file_repage=0
             strict_maxclient%=0
      The case of Versions prior to AIX version 5.2 ML04:
             Change: lru_file_repage=0

 These values must be set in order for ALTIBASE XDB to operate properly.
 They must be set such that they are suitable for the system configuration.
