Starting Isis

nms-isis

nms-isis start is the script that initializes isis.

Initializing Isis

To initialize isis, complete these steps:

1. From the nmsadmin user name type:

nms-isis start

This script will return when the isis process is running. To get the status of the isis process, use this command:

nms-isis status

It will return "1" if the isis process is running or "0" if it is not running.

2. When complete (which could take up to a minute or more), type:

cmd status

This determines if isis has successfully started and will provide information similar to the following:

cmd: my_site_no = 1

my_host = 127.0.0.1

Isis version = V3.4.14 Build: 20 $Date: 2010/06/09 19:03:03 $

verbose mode = off

3. If it has started successfully, type:

cmd sites

Result: isis lists all connected machines. For example:

tstaix01:cesadmin$ cmd sites
*** viewid = 1/1
tstaix01.[siteDomain].com [site_no 1 site_incarn 3]

Stopping Isis

To stop isis, issue the following command:

nms-isis stop

Starting Isis on Non-Default Ports

Isis may need to run on ports other than the default ports listed in the sites file. It is common to separate different sets of services by running isis for those services on separate network ports. For example, a configuration system may run on 1601, 1602 and 1603, while the model build services run on ports 1701, 1702 and 1702. Therefore it may be necessary to switch a client from one set of isis ports to another.

To start isis on a non-default port, complete these steps:

1. To check which ports to use, at the prompt type:

echo $ISISPORT

This returns the port configured for this environment.

2. As the nmsadmin user, set ISISPORT to the desired isis port number. For example:

export ISISPORT=2032

3. Then run nms-isis start as per usual. The nms-isis start script will take care of setting up isis on the proper ports.

Results:

• A new sites file called sites. $ISISPORT will be created from the existing sites file.
