Issue/Introduction

Where does the "Percentage of models activated" message seen in the SpectroSERVER VNM.OUT file come from? I see it in the VNM.OUT file on some of my SpectroSERVER systems in the Distributed SpectroSERVER environment but not in all.

Resolution

The "Percentage of models activated" message in the SpectroSERVER VNM.OUT is seen when the $SPECROOT/SS/.vnmrc file contains the following parameter:

wait_active=yes

The "SpectroSERVER (.vnmrc) Resources" section of the  documentation states the following for the "wait_active" parameter in the .vnmrc file:

 

wait_active

Determines whether the server accepts connections as soon as all models are loaded or waits until all models are active. If set to Yes, a Control Panel message displays a running percentage of models that were activated during SpectroSERVER startup.

This command has the following format:

wait_active=no

Default: no.

Additional Information

Please reference the "SpectroSERVER (.vnmrc) Resources" section of the documentation for more information.

Why set wait_active=yes?

With "wait_active=no", once the models are loaded the SpectroSERVER will be set as available.  In a fault tolerant environment, the SpectroSERVER will fail back to the primary once set as available and the models activate in the background. The models will not be available for monitoring until active so this would not be ideal for 100% monitoring.   We will see the VNM model in an initial state until 100% of models are activated.
