From an account with suitable privileges try this command:

Or

HELP?

Google can be your friend here, too.

OpenVMS SDA

Or add the Google site: keyword to the search:

site:h71000.www7.hp.com

to target the search to the host name of the HP server that serves up the bulk of the HP OpenVMS content.

Re: How to switch to SDA mode in open VMS

an example of DKLOG

http://forums11.itrc.hp.com/service/forums/questionanswer.do?threadId=942732

Some would say if you don't know how to get to the SDA prompt then perhaps you should not be.

However the System Analysis tools manual documents SDA and some of the SDA exenensions
http://h71000.www7.hp.com/doc/82final/6549/

but DKLOG is not documented, nor supported.

See some examples from openvms.org

typlog
http://dcl.openvms.org/stories.php?story=08/12/04/2298229
will show the last lines of the logfile of a process

find_bg
http://dcl.openvms.org/stories.php?story=08/06/09/6088086
will show the BG devices of a process

bg_process
http://dcl.openvms.org/stories.php?story=08/12/02/3240441
will display the statistics about the BG devices of a process (the Tcpip network traffic for this proces)

What problem are you attempting to solve by looking at data generated by DKLOG?

It may be that DKLOG is the correct tool, but it's also possible that we can suggest a different approach.

DKLOG is quite powerful, but depending upon your configuration (specifically multiple paths per device [AKA multipath]), you may be a bit confused in trying to interpret it.
