    Can't install rhq-agent [fixed]

    Rudy YAYON Newbie

      Hi,

       

        I want to install the rhq-agent 4.5.1 on SuSE 10.1 64bits with the jdk 1.7.0_07.

        The server is runing well on a CentOS.

       

        When I run the command "./jdk1.7.0_07/bin/java -jar rhq-enterprise-agent-4.5.1.jar --install", I get the following output (which seems OK):

      ======================================

        I didn't meet the same issue on my CentOS server. I addition, I can run RHQ 1.3.1 on this SuSE server.

       

        Please help me on it as I suppose it could be a non supported OS issue.

       

      Thanks,

          try to start the agent with the --nonative command line option and see what happens. If it starts, the problem is going to be due to the native Sigar library crashing. If you still get the same thing, you might have to post your hs_err file - perhaps there is something in the stack trace of the native code that could help discern the problem. Most times when I've seen this is because Augeas crashes (this is a native library used by some of the plugins - unfortunately (against my own objections :-) the RHQ agent shipped with its own augeas library and that could be the cause of the issue. But let's see - try the --nonative and post hs_err file.

              I was able to install RHQ 4.3.0 but non most updated versions (4.4.0 and 4.5.1).

              I guess it is related to the OS version.

                The --nonative flag does disable usage of Sigar libraries after the agent starts. However, the agent still attempts at startup to load the library to decide if Sigar is available. As you pointed out, this crashes the JVM on some older Linux distributions. I fixed this issue in master; RHQ 4.6.0 is the target release for the fix.

                 

                A simple workaround for RHQ 4.5.1 is to remove after installation all sigar libraries from the agent lib folder.

                  Hi Stefan,

                   

                    This is very good news and I would like to thank you for your work.

                    I will try to install 4.5.1 and delete all sigar libraries (which I suppose are the files with the name "sigar" in it, not more, right?) and I will update you.

                    Regarding 4.6.0, do you have any release date?

                   

                  Regards,

                  Rudy

                    Now by running "./rhq-agent.sh --setup", I get the following output in the agent.log file:
