 The ALTIBASE XDB server needs sufficient memory space in order to function
 properly.
 Please set the value to 70% of system memory or greater.

 # dbc_min_pct and dbc_max_pct 
 dbc_min_pct and dbc_max_pct were renamed filecache_min and filecache_max,
 respectively, in HP-UX 11.31 and subsequent releases.

 # dbc_min_pct and dbc_max_pct 
 dbc_min_pct and dbc_max_pct were renamed filecache_min and filecache_max, respectively,
 in HP-UX 11.31 and subsequent releases.

 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.
