Set MJS Cluster Security

Security

Level

Description User Requi re ments

your system/network user name and

password, because the worker must

log you in to run the task as you.

• All users that tasks run as, require

read and write permissions to the

CHECKPOINTBASE folder and all its

subfolders.

The job manager and the workers s hould run at the same security level. A

worker running at too low a security level will fail to register with the job

manager, because the job m anager does not trust it.

Local, MJS, and Network Passwords

For any security, the job manager (MJS) identifies every job with the user

who submits the job. T he refore, whenever y ou access the M JS or a job, t he

MJS must be aware of w ho you are.

At security level 0, the MJS and job objects’

UserName property is set to the

any time. For all higher security levels, the first access to the MJS causes a

dialog box to open which asks for your username; if the security level is 2 or 3,

you must also provide a password. The username and password you provide

for the MJS needs to match your network username and password only if you

are using security level 3; otherwise, you can create a new username and

password unique for the MJS. For your convenie nce, you can choose how long

to save your username and password on the local computer, so that you do not

need to enter them every time you access your job.

For information about changing a password and logging out of an MJS, see

changePassword and logout.

SetSecureCommunication

To establish secure encrypted communication between job manager (MJS) and

workers, set the

USE_SECURE_COMMUNICATION parameter in the mdce_def file.
