Offline DB performance study
Offline Database is READ-heavy (99% reads / 1% writes due to replication), therefore it should benefit from various buffers optimization, elimination of key-less joins and disk (ram) IO improvement

Further analysis from Len's trigger spreadsheet for run 10124075
Hi
This is an look at further analysis of Len's spreadsheet file for Run 10124075 with a follow up on gain matching of run 10124072.
Replication
Replication enables data from one MySQL database server (called the master) to be replicated to one or more MySQL database servers (slaves).
Maintenance
Database maintenance tasks: monitoring, backup, upgrades, performance issues, server list etc...
Software Infrastructure Databases
There are several applications in STAR, which use databases as back-end. Those databases are not directly related to data analysis.
Online Databases
Online Databases
Online databases are :
onldb.starp.bnl.gov:3501 - contains 'RunLog', 'Shift Sign-up' and 'Online' databases
How-To: admin section
This section contains various pages explaining how to do typical STAR DB administrative tasks.
