Apache version shows, the architecture as 32-bit on HP PA-RISC why?

[GnanaShekar]

Hi,

I have downloaded the HP-UX web server suite V2.16 (for HP-UX 11i version 2 PA-RISC/IPF 64-bit) and insalled HP-UX apache-based webserver 2.0.58 in it on a HP PA-RISC server.

However, when I list the apache version, it shows the architecture to be 32-bit why?

-bash-3.00# uname -a
HP-UX banpchp6 B.11.23 U 9000/800 1335080362 unlimited-user license

-bash-3.00# ./apachectl -version

Please suggest,
Thanks & Regards

Shalom,

Because HP compiled apache 32 bit.

There may be 64 bit versions available as well, but its not going to make a difference. Apache doesn't need enormous chunks of memory where limiting it to a 32 bit address space is going to slow it down.

Hi,

If HP compiled apache only as 32-bit, then Why did they provide 2 separate installable (as listed below), one for 32-bit and one for 64-bit?

HP-UX 11i version 2 PA-RISC/IPF 64-bit
HP-UX 11i version 2 PA-RISC/IPF 32-bit

Please find attachment for more details.
Please suggest,
Thanks & Regards.

And the depot name you've downloaded is

HPUXWSATW-B216-1123-64.depot ?

[GnanaShekar]

Yes.

The depot name is:
HPUXWSATW-B216-1123-64.depot

Please suggest,
Thanks & Regards.

AFAIK, apache v2.x 32 bit should be installed under /opt/hpws/apache32 ... so its documented at least. In your case I see that HTTPD_ROOT is
/opt/hpws/apache.

I don't have currently Apache around on 11i v2 to check. Anyway, in the release notes file /opt/hpws/hp_docs/apache/apache.release.notes you see if one installed is 32 bit or not.

It makes a difference if your plugins are only 64 bit. And the other way around.
