This is what enables the database to recover data that were lost due to a media failure, loss of power, or any other type of disaster. Each time the online line redoes logs filled up in a log group, the DBMS issues a log switch that will move the log writer process from the current redo log group to the next one in line. The archive background process begins archiving the data in the full online log group files to the archive log files. This is done simultaneously for each log file in the group. If media recovery is needed at the time that the database needs recovery, then the DBMS will search through the archived log files to find the ones that need to be used.

According to the test, every person has one dominant trait in each category. The theory is that every person will fall into one of the 16 personality types.

This test can be used as a guide to help pinpoint personality traits, possible career paths, and provide some explanation for why and how we pick our friends, romantic partners and how we interact with the outside world as a whole.

The other test that is used is The Big 5, this test has 5 main categories, where as the MyersBriggs has only 4.

This test is shorter and less invasive than the Myers-Briggs, and has the acronym that gives a percentage of that letter found from the results of the few questions answered. “OCEAN” standing for Open-Mindedness, conscientious, extraversion, agreeableness and negative emotionality.
