This chapter provides a step by step guide to getting started running JAMS jobs on Microsoft Windows NT/2000.
There are a number of tasks which must be completed before you can run jobs under Windows NT/2000. These tasks include:
The JAMS Agent for Windows NT must be installed on any Windows NT/2000 machine which will run JAMS Jobs. The Agent can be installed on any class of NT system, from Workstation to Datacenter Server. Refer to the JAMS Installation Guide for a detailed explanation of the Agent installation procedure.
Installing the Agent also installs a JAMS Control Panel applet which is used to configure the Agent. This control panel applet lets you configure three settings:
The temporary directory is used to store temporary command procedures. These command procedures are deleted when a job completes. For Windows NT V4.0, the default can be used. For Windows 2000, you must specify a directory which can be accessed by the JAMS Agent and the accounts which jobs will run under.
The Requester Secret is used to authenticate JAMS Servers before they can even attempt to run a job. The default is blank which disables this check. If you use requester authentication you must set the same secret here and on the server. You set the requester secret on the server with the JAMS SET AGENT/SECRET="secret" command.
The Agent will listen for requests on the TCP/IP port specified. The default is port 77 which is reserved for private RJE systems. The port on the agent must match the port on the server. You set the TCP/IP port on the server with the JAMS SET AGENT/PORT=n command.
If checked, the Agent will allow jobs to run with interactive access to the desktop. Interactive access must be requested by setting the INTERACTIVE option in the job's execution method.
In order to run a job under Windows NT, the JAMS server must supply a valid NT username and password. You must use the SET USERNAME command to define the username/password combinations. You can also specify an access control list (ACL) which is used to determine who can use the username.
Here is an example of an NT user definition:
JAMS> SET USERNAME ADMINISTRATOR/PASSWORD="SecretPassword" - _JAMS> /ACL=(IDENTIFIER=[1,*],ACCESS=SUBMIT) |
This example defines the NT username "Administrator". The password must be the correct password for the Administrator account but, the password isn't checked until a job is run under this username. Note that the password is enclosed in quotes to preserve the case. The ACL will allow OpenVMS users that are in the [1,*] UIC group to specify "Administrator" as the username in a job or system definition.
JAMS jobs run as batch processes under Windows NT. The NT account that the batch job will run as must have the "Log on as a batch job" user right. You can grant this right to specific accounts or, grant the right to a group and make the accounts members of the group.
Under Windows NT V4.0, you must grant the "Log on as a batch job" right on each machine which will be running the JAMS Agent. You only have to grant the right on one domain controller and it will propagate to the other domain controllers in the domain. It will not propagate to member servers or workstations, you must grant the right on each of those machines.
You can use User Manager for Domains to grant the right for both the domain and individual machines. Select the User Rights option from the Policy menu. You must check the "Show Advanced User Rights" check box to display the "Log on as a batch job" user right.
To manage user rights on member servers and workstations, select the Select Domain... option from the User menu. Enter "\\machinename" in the Domain field and click Ok. You will then be connected to the specified machine and you will be able to manage the user rights on that machine.
Under Windows 2000, you can grant the "Log on as a batch job" right at the domain level or local level.
To manage rights under Windows 2000 you use the "Local Security Policy" or "Domain Security Policy" Administrator Utilities.
The NTRights.exe utility is included in the Windows NT Server 4.0 Resource Kit supplement 3 and in the Windows 2000 Resource Kit. If you have this utility you can grant the "Log on as a batch job" right with a command like this:
ntrights +r SeBatchLogonRight -u user_or_group -m \\computername |
Note that the rights name is case sensitive.
Once you've completed the initial setup required to run jobs on Windows NT/2000, defining jobs is simple. There is essentially no difference between an NT and an OpenVMS job definition. The key differences are:
JAMS ships with three Windows NT specific execution methods. You can create additional execution methods with the CREATE METHOD command. The three Windows NT execution methods are:
| Method | Description |
|---|---|
| NT | Runs an NT command file. |
| NTCMD | Runs a single NT command. |
| NTPARSE | Runs an NT command file which has been parsed for JAMS parameter references. |
Let's take the DEMOJOB1 from the Chapter 2 and make it into a Windows NT job.
DEFINE JOB DEMOJOB1
SYSTEM DEMO
METHOD NTPARSE
AGENT NODE NTNODE.YOURNAME.COM
AUTO SUBMIT
SCHEDULED DATE "MONDAY, WEDNESDAY, FRIDAY"
SCHEDULED TIME 14:00
PARAMETER P1
PROMPT "Start Date"
DATE
DEFAULT VALUE "FIRST DAY OF MONTH"
END_PARAMETER
PARAMETER P2
PROMPT "Sales Category"
TEXT LENGTH 4
DEFAULT VALUE "ALL"
END_PARAMETER
END_JOB
|
Notice that the only difference between the NT and OpenVMS version of this job is METHOD and AGENT NODE lines. One other key difference is the default filename. The execution method defines the default file extension so the OpenVMS version would use a default filename of DEMOJOB1.COM and the NT version would use a default filename of DEMOJOB1.CMD. Both versions would look in the directory specified in the DEMO system definition.
