Operating station B2600
I have a redundant mb300 network consisting of 12 operating stations hp b2600 working under unix hp-10.20 with advacommand 1.8.6.
I have one of the 12 stations need to be restarted every 3 days due to slow response in changing pages.
I changed the station , harddisk , increased ram but in vain.
But I didn't change the rta board pu515a,transceivers or network cables.
So could the problem be in one of them?
Note:all the station have the same software programs but they are different only in ip address, process sectioning ,delegations.
Hmm... the display exchange speed of a B2600 is often hard to match, even with 10x more CPU power a modern computer has today.
Sounds like a memory leakage to me.
Try comparing the output from the "top" command (HP's command line equivalent to the Task Manager in Microsoft Windows). With "telnet" or "rlogin" you can perform the measurement remotely without disturbing what is going on at its console.
With some (minor) effort top will tell:
- top CPU using process
- memory usage
- swapping (due to lack of memory)
Can't remember if "top" in HP-UX allow you to change sort column with the "<" and ">" keys as top does in more modern operating systems. Try "?" or "man top" to check online help in case you want to know. Googling "hpux top manual" should work too.
Do also check/compare disk usage with "bdf" as a full disk could give random effects.
Kernel issues should tarnish the output of the "dmesg" command. Check/compare with healthy machines.
Over the "lifetime" of the sick machine, some value(s) ought to start deviate heavily. Can you find which?
If any ABB process is involved; try enabling the system log (can be done in Station Settings, then perform a Function Restart to let it kick in). The log file (/products/log/dcSystem.log) may contain vital evidence.
Full disk due to printer problems is not uncommon. The "cancel" command can be used to erase print jobs. If I remember correct, "cancel -a" made from root account should empty the print spooler queue from all (stuck?) print jobs. You must of course find what is printing to get a permanent fix in place.
Please update the thread!
