Installing <strong>Caché</strong> on UNIX and Linux<br />
4.7.7 IBM AIX<br />
The default settings of several AIX parameters can adversely affect performance. For detailed information<br />
on the settings and recommendations, see the AIX Platform Notes section of the Calculating<br />
System Parameters for UNIX and Linux appendix.<br />
4.7.7.1 PowerPC System Requirements<br />
Current versions of <strong>Caché</strong> are only supported on PowerPC. PowerPC AIX 5.2 and later support a 64-<br />
bit kernel on POWER4, POWER5, or equivalent hardware.<br />
The following table lists the allowable combinations of runtime, kernel, and hardware configurations:<br />

Note: 64-bit <strong>Caché</strong> requires combination 5.<br />
To determine whether the CPU is 64-bit, issue the following command:<br />
# bootinfo -y<br />
This returns 64 for POWER3, POWER4, or POWER5 and returns 32 on older PowerPC systems.<br />
To determine whether the 64-bit runtime environment is installed, issue the following command:<br />
# lslpp -l bos.64bit<br />
To determine whether the 64-bit runtime environment is loaded at boot, issue the following command:<br />
# grep load64bit /etc/inittab<br />
To determine whether the system is running the 64-bit kernel, issue the following command:<br />
# bootinfo -K<br />
Alternatively, confirm that /unix points to unix_64, rather than unix_up or unix_mp:<br />
