Oracle 12737: How to Troubleshoot Performance Issues（oracle12737）
As an Oracle Database Administrator (DBA), diagnosing and resolving performance issues related to the Oracle database is a critical component of job performance. Oracle’s “Database Performance Tuning Guide” explains how to diagnose and resolve a variety of problematic issues. The manual explains in detail how to troubleshoot Oracle Database 12737 performance issues. This guide explains how to quickly and continuously monitor an Oracle database’s key performance metrics and tune it for optimal performance.
The Oracle guide suggests using the RDA tool – the Oracle Database Real-Time Diagnostic Analyzer – to detect the issue and accelerate issue resolution. RDA can monitor key performance metrics such as system time, response time and latencies, read/write throughput, and major system events. It also monitors pertinent system resources such as memory, I/O and CPU. By monitoring these metrics, RDA can determine if they are performing within expected parameters and if not, what specific areas are causing performance problems.
RDA can also provide guidance on the type of tuning steps necessary to improve performance. For example, it can provide recommendations on the optimal memory sizes and other system resource adjustments that can improve the performance of an Oracle database instance.
The Oracle guide also provides detailed guidance on troubleshooting Oracle trouble tickets. Oracle DBAs can open trouble tickets with Oracle Support or directly in Oracle’s My Oracle Support portal. Once a trouble ticket is opened, Oracle Support will provide guidance on specific steps to take to resolve the issue. DBA’s should include detailed information about the issue, the environment and the steps taken to investigate and resolve the issue.
Overall, troubleshooting Oracle performance issues is a critical component of DBA job performance. Oracle’s “Database Performance Tuning Guide” provides in-depth guidance on how to quickly and continuously monitor an Oracle database’s key performance metrics and tune it for optimal performance. Furthermore, the guide provides clear guidance on troubleshooting Oracle trouble tickets and general Oracle performance diagnostics. By following the guidance in the guide, DBA’s can quickly and effectively troubleshoot and resolve Oracle performance issues.
