Dudley,

Welcome to OpenVMS...

$ HELP/MESSAGE PRCREAT

PRCREAT, error creating process

Facility: JBC, Job Controller

Explanation: The job controller encountered an error in creating a process
for a terminal that is attempting to log in. This failure
usually occurs when there are no more process slots available
in the system to create a new process.

User Action: Try again later when fewer users are competing for system
resources. Also, notify the system manager of this situation.

$ SHOW MEMORY/SLOT

will show you how many processes you can create and
how many process slots are currently in use.
If you need to allow more processes, then you will need
to edit SYS$SYSTEM:MODPARAMS.DAT and either include
an entry MAXPROCESSCNT=n where n is a number larger
than the current value, or edit any existing entry
for that parameter.

Once this has been done you will need to execute the
AUTOGEN procedure to update the value so the new
value is used after the next reboot.

$ SYS$UPDATE:AUTOGEN SAVPARAMS SETPARAMS

should do the trick, then you will have to organize
a reboot.

Dave.

DM,

Although Dave's suggestion of running out of process slots is almost certainly correct, there are other possibilities. Depending on where you're seeing the message, there may be a secondary message giving a reason.

If Dave's suggestion doesn't help, please post the EXACT command you're issuing that is resulting in this message, and any other messages you may be getting.

Most possible causes are related to quotas and system resource limits.

I am not even getting the chance to enter a command. ANy key I hit on the console or as soon as I click on a telnet session to the server I receive this message. We can't even get a prompt to boot the server. Is my only alternative to power cycle the server. Thx

why not crash the system to get a crash dump you can enjoy afterwards.
If its an alpha then control-P on the console to get the >>> prompt then enter the word crash and the system should crash dump and reboot.
If its a VAX then the instructions depend on the model.

I attempted the cntl-p but this or anything I hit on the system console just gives this msg. again. I cannot do anything on the console to get a response other than the err. msg. I work at the BellSouth account and we are under a system freeze due to the recent hurricane and I am looking for a way to recover from this without a reboot but I am afraid it is looking like there isn't any other way. THANKS

Hi DM,
"I cannot do anything on the console to get a response other than the err. msg" does it means you can type something on console?
The above messege "JBC-F-PRCREAT" is job message, not a interactive message.
I can imagine your system ha not any slot avaiable, but I can guess there is at least one connection avaiable to type some command.

If control-P does not work on the console then for some models of alphaserver there is a halt button.

If you have Availability Manager or AMDS already configured to be able to write to the target system (and you really should do if you have not) then you can crash the node using that.

It is true. Nothing will give any response when hit on the system console except the error msg. I have tried interrupt, halt, break, enter, everything.

Thanks,
