Sun Update Connection - Enterprise 1.0 Administration Guide

Deploying Jobs With Sharing Hosts

In an Sun Update Connection – Enterprise system without sharing hosts, you can run any job on any host or any group. You can create Custom groups of any combination of master hosts.

Once you have created a sharing host, there are limitations to the jobs that you can deploy.

Job Restrictions

Synchronization between the sharing hosts and their master host must be maintained. Therefore, jobs that include sharing hosts have special limitations, to ensure and to troubleshoot synchronization.

The following limitations apply to deploy jobs with a host list that includes at least one sharing host:

The complete Master Group must be included on the host list
Only one job can be run on a Master Group at any time
After the Master completes a job, all of its sharing hosts must complete the job

Job Processes

After Sun Update Connection – Enterprise confirms that the entire Master Group has been selected for a job with sharing hosts, the job begins.

The job is sent to the master host on the host list.
The agent of the Master runs the Dependency Resolver and job procedures.
On success:
- If the Masters in the host list do not have sharing hosts, the job ends.
- If it is a Simulate mode job, Sun Update Connection – Enterprise checks the sharing hosts and then the job ends.
- If it is a Deploy job, Sun Update Connection – Enterprise checks that the sharing hosts are synchronized with their master host. If this check is successful, the sharing hosts take the job solution that the master host used and run the same tasks. sharing hosts do not try to find a new solution; they must follow the same steps that their Master took.

If a Problem Occurs

Unsynchronized Sharing Host
Situation	An error is given for a sharing host in the Status window, stating that the host is not synchronized with its Master.
Explanation	A sharing host was unable to successfully complete a job and is no longer synchronized with its master host.
Solution	1. Select the sharing host in the Hosts window. The Synchronize button is enabled. 2. Click Synchronize. A job beings that works on only this sharing host. It makes any changes necessary to make the software configuration of the sharing host compatible with the master host. The Synchronize Job feature is available only to an user with full permissions, and can be run on only one sharing host at a time.
