How to set JAVA_HOME environment variable on Mac

Note: This tip is for Mac OSX 10.5 or later


Apple recommends to set the $JAVA_HOME variable to /usr/libexec/java_home, just export $JAVA_HOME in file ~/. bash_profile

 You might not have .bash_profile present on your system already. No worries we will create/update the profile in next step.

Open Terminal:

$ vi ~/.bash_profile

Initially the vi editor will not be in edit mode, press 'i'.

Update file by exporting variable:


export JAVA_HOME=$(/usr/libexec/java_home)

to the file (in the vi editor which we opened using the previous command)

Saving and Closing the .bash_profile file opened inside vim editor:

Press escape (while still inside the vi editor)
type ":wq!" or press "Shift + zz" to save and exit the file.

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...
