  Oracle Tips by Burleson


Is the IT employee knowledgeable enough to accomplish his or her job responsibilities with minimal assistance from others? Is this knowledge broad across diverse aspects of the job, such as multiple DBMS’s (Oracle, Sybase, Informix, and DB2)? Does this knowledge extend beyond the immediate job responsibilities to include other related IT groups and the business itself?

Knowledgeable Worker Story

The more fortunate IT managers have employed some very talented DBAs who possessed very broad knowledge. In one particular case, an IT employee was proficient in supporting Oracle, Sybase, and Informix databases. His grasp of the surrounding environments and their relationship to the database was excellent.  

For example, tuning an Oracle database does not stop at the database. There are many aspects of the OS, filesystems, hardware, storage, network, and application code that have a large impact on database performance. He analyzed OS memory paging and swapping, disk I/O, the number of processors, disk striping, the storage cache, network latency, and application code efficiency (SQL and PL/SQL), to name a few. This extensive range of knowledge helped to bring together the other IT support groups in resolving difficult system performance issues and outages.
