Logs files in Virtual Vault

[Kenny Chau]

Hi all,

I had a web server running in HP-UX Virtual Vault OS in A-class machine. There are some logs files that growth quite rapidly. So I want to trim those log files. However, my colleagues had deleted one of the log files accidentally. The log files are located in /opt/server4/https-/logs and the log files are "access" and "errors". My colleagues had deleted the "errors" and I had tried to touch a same file with the same owner, group and permission, but the file did not growth. It seems the log can not update that file. So in this situation, what can I do to make the log update that file?

Thanks very much.
Kenny.

I'm thinking you probably got to restart the http daemon or whatever processes that writes to these log files.

Thanks for your quick reply, SK. I had found that there is a ns-httpd daemon running which I think it will write logs to those files. However, how should stop this daemon and restart it? I found it in /opt/server4/bin/https/bin but the permission is 010. So how can I start this daemon? Any effect to the servers or our web page?

Thanks.
Kenny.

The safest way to restart any "non-OS" program/process is via the startup script in /sbin/init.d. Is there one for ns-httpd in this directory ? There should be otherwise how would you startup the daemon each time the system reboot, right? For the other question, I can only speak for myself where I have Netscape Enterprise server and restarting ns-httpd would definately affect the users where they would just not being able to surf until it comes up.

Thanks SK. However, I can not find the ns-httpd under /sbin/init.d directory. I only find that daemon under /opt/server4/bin/https/bin. So I am not sure how to restart it.

Do you have any idea?

Thanks.
Kenny.

It may not be the file "ns-httpd" but rather embedded in another script file. Do this ..
# cd /sbin/init.d
# grep httpd *
==> if not found then you'll have to restart ns-httpd manually.

I can't quite remember the command .. the way I used to do it is like so ..

# cd $NETSCAPE/bin
==> I have $NETSCAPE set in my profile
# ./ns-httpd -d $NETSCAPE-CONF
==> again I can't recall the full path of the config file.

Lets look at the process you have.. can you post this ..
# ps -ef|grep httpd
That will help to determine how the daemon is startup, which option and which config file, etc.

[Kenny Chau]

Well, only the file "vvmgrhttpd" contains the word httpd and all the lines contain the word "httpd" is all from the word "vvmgrhttpd". So I don't know if this daemon is for starting the ns-httpd daemon.

Also, the ps -ef | grep httpd is:

ns-httpd -d /opt/server4/https-/config
/opt/vaultTS/bin/vvmgrhttpd
ns-httpd -d /opt/server4/https-admserv/config

So what command can I use to start the ns-httpd daemon?

Thanks.
Kenny.

[S.K. Chan]

OK we're close .. it looks like "vvmgrhttpd" is a seperate daemon from the ns-httpd, so we can't use the startup in /sbin/init.d.
That leaves us with these ..

ns-httpd -d /opt/server4/https-/config
and
ns-httpd -d /opt/server4/https-admserv/config

Since I'm not sure if both of them are parent-child related processes or separate processes I still need the PID, PPID from the output

# ps -ef|grep ns-httpd

This time post the complete line so that we can see the PID and PPID. Thanks..

Hi,
In netscape, you can run many instance of http. In your case it is only one.
ie.
"ns-httpd -d
/opt/server4/https-admserv/config"

So in general you should have a 'start', 'restart' and 'stop' script under "/opt/server4/https-admserv/"
With the help of this you can restart your netscape. Also the logfile is not getting generated because of the time-stamp. So on re-starting it should go fine.

Thanks guys for your answers. I think I should need to restart the ns-httpd daemon. I had searched from the ITRC site that there is a watchdog process(uxwdog) running together with the ns-httpd and if I kill the ns-httpd daemon, it should restart automatically, which is the same as Gnana mentioned: restart, as I had read the script. However, I can not do this at this moment because my boss did not allow to. So I will try this later to see if it will fix my problem and I will update you guys for this.

Thanks very much for your help.
Kenny.
