Special Considerations<br />
Important:<br />
<strong>InterSystems</strong> recommends that you set the sys_v_mode to 1 on all file systems and<br />
directories that <strong>Caché</strong> uses to ensure smooth functioning of the system. See open(2)<br />
for more information.<br />
4.7.5.2 Tru64 UNIX Mount Point Restriction<br />
Do not use /usr/local/etc/cachesys as a mount point for a <strong>Caché</strong> instance on Tru64. The <strong>Caché</strong> installation<br />
and upgrade process uses the mkcdsl command on this directory; the command fails if the directory<br />
is anything but the registry directory.<br />
Volumes must be mounted using the System V File System (sysv) option. See mount(8) for more<br />
information.<br />
Note:<br />
If you want to use a different file system — for example, Advanced File System, (AdvFS)<br />
— set the group ownership from the root down the directory tree to cacheusr.<br />
4.7.6 HP-UX<br />
See the HP-UX Platform Notes section of the Calculating System Parameters for UNIX and Linux<br />
appendix for detailed configuration information.<br />
4.7.6.1 HP-UX pwgrd Daemon<br />
HP-UX distributions run a daemon (pwgrd) that caches password and group information from network<br />
queries. <strong>InterSystems</strong> does not explicitly enable or disable it, but prior to the 9/2008 Release of HP-<br />
UX 11iV3, it was enabled by default; beginning with that version, however, it is disabled by default.<br />
As a result of pwgrd being disabled, when installing <strong>Caché</strong> with a network user as the instance owner,<br />
users may see the following error: chown: unknown user id integ. To prevent the error from<br />
occurring, you should enable pwgrd.<br />
4.7.6.2 HP-UX Kerberos Client Requirements<br />
For Kerberos to work properly on the HP-UX 11i platform you must have the Kerberos Client<br />
(KRB5CLIENT) version 1.3.5. Verify you have the latest upgrade for HP-UX 11i v2 that includes<br />
this version. HP-UX 11i v3 includes the proper version of the client.<br />
4.7.6.3 HP-UX Random Number Generator<br />
<strong>Caché</strong> requires the HP-UX Strong Random Number Generator component for true entropy for its<br />
cryptographic random number generator. HP-UX 11i v2 now includes this component by default.<br />
