Multiple entries in "rhq_agent_install" table
in the above case, If we install multiple times, we can see more than one entry in "rhq_agent_install" table,
rhq=# select * from rhq_agent_install;
id | mtime | agent_name | install_location | ssh_host | ssh_port | ssh_username | ssh_password

Screen shot is attached.
Its possible multiple rows in rhq_agent_install table will show up under a few scenarios. We clean it up later when other things happen. In other words, rhq_agent_install table is an internal implementation detail that shouldn't concern end users. As for the issue of installing multiple agents on the same machine, I am going to look into doing something like looking in the rhq_agent table to see if one is already registered. I might be able to use rhq_agent_install table as well, but I'll figure this out once I start working on it. I think the best thing to do here is to see if the port is already in use. If the port is in use, not only will this abort if another agent was installed, but it will abort if anything has taken the port the agent wants to use. This is helpful for other use-cases as well (as in the case of installing an agent on a machine where some other application is using the port the agent wants to use). This has been implemented, git commit to master: c911e9a Bulk closing of RHQ 4.11 issues, now that RHQ 4.12 is out. If you find an issue with those, please open a new BZ, linking to the old one. |
Description of problem: Try to install remote agent more than one time on same machine with different locations with same user. First installation went success and agent up and running. Second time installed on different location and up, but throws an exception saying the port already in use. ----------------snap--agent.log---------------- 2014-04-24 14:29:52,512 ERROR [main] (org.rhq.enterprise.agent.AgentMain)- {AgentMain.start-failure}Failed to start the agent.

Navigate to "Administration-->Agents-->New" 2. Enter remote box details (Agent should not be installed), give some location, example: /tmp/ 3. Click on "install Agent", will be installed successfully 4. Again Navigate to "Administration-->Agents-->New" 5. Enter remote box details same as in step #2, give different location location, example: /tmp/another/ 6. Click on "install Agent", will be installed successfully. But the port already use with agent installed on step #3. 7. Second installation should refer first installation location and should not proceed more than one time. Actual results: Permits second installation on different location for the same user on the same machine. Expected results: Should not install more than one time, if a agent is already installed on different location. We should track with some reference in common location.
