Ciscoworks 2000 and Semaphores

[Craig Williams]

Hi all,

Ever since we have installed CW2000 we are having problems with it using all the semaphores.

Was just wondering if anybody else has experienced the same probs and know of a fix for this.

Have tried changing the semaphore parameters but CW2000 once started uses them all straight away?

Any help would be much appreciated.

In most of the HP-UX machines, the values of nfile (kernel parameter for maximum number of open files) and ninode (parameter for maximum number of open inodes) are low by default. When CW2000 is started without tuning these parameters, the file table gets full and the system must be rebooted.

CW2000 might also misbehave due to insufficient kernel resources such as semaphores or shared-memory segments. As a result, before starting CW2000, the kernel must be properly tuned.

At the end of a successful install, the install script checks the kernel parameter values to ensure proper kernel tuning. If the parameters are found to be low, you are notified with the following message:

INFO: Needs to tune the kernel.This will require a reboot
Proceed with kernel rebuilding? [Y]


Upon confirmation, the script builds the kernel as per the requirements. Before overwriting the kernel, you are again prompted with the following message:

INFO: Kernel build completed.
Overwrite /stand/system and Reboot with new kernel ? [Y]


Upon confirmation, the script completes the installation and reboots the machine from the newly built kernel.

If the kernel build is unsuccessful, daemons will not be started. You will be asked to tune the kernel and start the daemons.[CSCdk62037]

Craig, still getting this problem then. Have you check the
afore mentioned kernel params ?

We encountered the same problem. Let me guess:
HP/UX 11.0 64 bit?

Support from Cisco has said that HP/UX 11.0 64 bit is currently unsupported but will be covered in a new release RSN. If anyone knows better, please contradict me.
