If you have a large JON environment or are collecting a lot of metric data, you may want to turn on auto-vacuum to ensure the database utilizes its available disk space efficiently. You do this by performing the following steps: • Shutdown JON Server • If you are using the embedded Postgres, take note that "jon-server.sh,bat stop" also shuts down the Postgres DB • Execute the following SQL using a Postgres tool like pgAdmin (this may take a very long time to run): • If you are using the embedded Postgres, start the DB via bin/db_start. Sh and then use bin/db_psql.
Sh • vacuum full verbose; • Shutdown your Postgres database so you can reconfigure it • If you are using the embedded Postgres, its bin/db_stop. Sh but stopping the JON Server stops the DB for you automatically • Edit the postgresql. Conf file in order to turn on auto vacuum: • If you are using the embedded Postgres, this file is located at hqdb/data/postgresql.
Conf • autovacuum = on • Edit the postgresql. Conf file and bump ... more.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
