Java 8 JMX Default Metrics

This is more of a note. Here you can find default types and attributes for JMX on top of Java 8.


Code: I will clean and explain it later :( 

private static void WriteAttributes(final MBeanServer mBeanServer, final ObjectName http)
            throws InstanceNotFoundException, IntrospectionException, ReflectionException
    {
        MBeanInfo info = mBeanServer.getMBeanInfo(http);
        MBeanAttributeInfo[] attrInfo = info.getAttributes();

        System.out.println("Attributes for object: " + http +":\n");
        for (MBeanAttributeInfo attr : attrInfo)
        {
            System.out.println("  " + attr.getName() + "\n");
        }
    }

Laravel XAMPP MySQL artisan migrate install error mysql.sock

In my previous post I wrote about setting up Laravel 4 on Mac with XAMPP . When I tried to use migrations (using artisan) I faced some issue. I will also post about Laravel migrations soon.    php artisan migrate:install Error :                                                     [PDOException]                                       SQLSTATE[HY000] [2002] No such file or directory                                              Solution : We need to tell artisan which mysql we want it to use. For this to work we need to porivde it with mysql.sock which we want it to use. So change your database settings like this: 'mysql' => array( 'driver'    => 'mysql', 'host'      => 'localhost',     'unix_socket' => '/Applications/xampp/xamppfiles/var/mysql/mysql.sock', 'database'  => 'wedding', 'username'  => 'root', 'password'  => '', '

Press ok The article has now been added to the publisher We now need to recreate the snapshot Right click the publication and select – “View snapshot agent status”. Click start to regenerate snapshot. Now right click on the subscription (I have both on same server you may have on different servers) and select “View synchronization status” Click on start on the agent. The schema changes will propagate to the client if you have "Replicate schema changes" property set to true in the publisher.

Check SQL Server Job status (State) using sp_help_job and xp_sqlagent_enum_jobs

This article is about checking the status of a SQL job. In our work place we have lot of SQL jobs. These jobs will run whole day and are business critical. They will load the data and generate extracts which will be used by business people. Thus, it becomes quite essential to support the system efficiently so that the job finishes in time and as desired. Also, while designing a new system sometimes we need to check the dependency of one job over another. In such scenario we need to check whether a particular job has finished or not. All this can be achieved in SQL Server by using the procedures:- sp_help_job xp_sqlagent_enum_jobs Note: xp_sqlagent_enum_jobs is an undocumented proc inside of sp_help_job and is used extensively to get SQL agent job information. sp_help_job: This procedure gives some insight into the status, and information, about a job. This stored procedure provides information such as last start time, job status etc. Syntax sp_help_job { [ @job_id= ] jo
