ORACLE Databases: Maintaining Performance

ORACLE is not an solo job, as the databases interfaces with hundreds of features and components. Info architects, database administrators (DBAs), storage managers, and a host of other business personnel must work put together in order to properly configure storage for ORACLE and properly tune the storage for optimal performance. I’ve included a few a few tips in order to simplify system configuration and performance fine tuning on your storage system. 1z0-064 dumps

Configuring the Big Several

There are four major hardware components to consider when building or fine-tuning an Oracle hardware facilities. Architects must ensure a

Memory space
Info Storage
Network
Although often an improvement in one or many of the above components may produce an improvement in performance, there are limits to that particular improvement depending on which variable may be creating a performance constraint.

Properly identifying the challenge component will make it easier and more cost-effective to minimize any performance constraints that may be occurring. Any kind of performance increases that end result from adding hardware should be thought about initial relief, as increased program use is likely to cause the same problems soon.

Talk with a storage expert to determine what system is more likely to scale most effectively for your environment when dimension or deploying a new system to support your Oracle databases.

Symptoms and Problems

Slow Physical I/O – This results when disks have been designed improperly or too few resources have been allotted to support the data source.

Excessive CPU Usage – Excessive CPU use means there is little to no idle CPU on the storage system. This kind of can occur when a system has not recently been sized adequately due to inability of the PROCESSOR to scale and meet demand.

Outages – This could occur when proper redundancy has not been built into the system as a way to account for outages
Frequently, the symptoms are indication of an root problem in the hardware, poorly configured solutions, or untuned SQL statements.
