What does the OS version mean?

Our server is showing the following info:

HOST NAME : apache
OS SYSTEM : OSF1
OS RELEASE : V5.1
OS VERSION : 1885
MACHINE : alpha

what does the OS version here mean? Does it mean patch level?

Thanks!

Re: What does the OS version mean?

The 'OS Version' is just another way of specifying whether the OS is V5.1A or V5.1B etc. It doesn't say anything about the patch level. Try 'sizer -v'...

Use 'dupatch -track -type kit' to find the patch version

Re: What does the OS version mean?

thanks for the info.

Ok, I tried "sizer -v".
Below i what returned :

Compaq Tru64 UNIX V5.1A (Rev. 1885); Mon May 31 09:15:45 CDT 2004

It is showing "Rev.1885", what is that?

Also, the time " Mon May 31 09:15:45 CDT 2004" means the time when the system was upgraded into V5.1A, right?

Re: What does the OS version mean?

'Rev.' is 'OS Version' which as BL mentioned is another way of specifying whether the OS is V5.1A or V5.1B etc.

The time indicates when the system was installed, upgraded, or patched. On one of our systems we have:

# sizer -v
Compaq Tru64 UNIX V5.1B (Rev. 2650); Sun Jun 5 08:31:56 EDT 2005

June 5th was the date we installed a performance patch.

Re: What does the OS version mean?

Thanks BL and Victor!

Then it looks like our system has not been patched for more than 1 year.

Victor, will you provide me a pointer where to find all those patches? Thanks!

Here's the URL I use:

Click on the Tru64 UNIX link under Software Patches.

Re: What does the OS version mean?

Lei Li,

Michael is correct, it just so happen that the performance patch we installed did rebuild the kernel.

You can also ran the following command:

#grep KITNAME /var/adm/patch/log/event.log

Check the Kitname and match it against the site given previously.
