Understand the importance of baselines for Oracle performance tuning<\/h3>\n\n\n\n<p>This is one of the most powerful, practical tuning methods to maintain an established performance baseline that you can refer to when a performance problem occurs.&nbsp; Set performance targets and have a firm understanding of your system capabilities by quickly identifying peak usage periods.&nbsp; If you consistently measure existing performance, you can see how your database should be running.&nbsp; This will be helpful when turning around bottlenecks that may come.<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"512\" height=\"420\" src=\"https:\/\/www.bridge-global.com\/blog\/wp-content\/uploads\/2020\/10\/Understand-the-importance-of-baselines-for-Oracle-performance-tuning.jpg\" alt=\"Maintain an established performance baseline to improve Oracle database performance\" class=\"wp-image-45755\" srcset=\"https:\/\/www.bridge-global.com\/blog\/wp-content\/uploads\/2020\/10\/Understand-the-importance-of-baselines-for-Oracle-performance-tuning.jpg 512w, https:\/\/www.bridge-global.com\/blog\/wp-content\/uploads\/2020\/10\/Understand-the-importance-of-baselines-for-Oracle-performance-tuning-300x246.jpg 300w, https:\/\/www.bridge-global.com\/blog\/wp-content\/uploads\/2020\/10\/Understand-the-importance-of-baselines-for-Oracle-performance-tuning-366x300.jpg 366w\" sizes=\"auto, (max-width: 512px) 100vw, 512px\" \/><figcaption>Maintain an established performance baseline<\/figcaption><\/figure><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">2. Work towards tuning inefficient SQLs for better Oracle database performance problems<\/h3>\n\n\n\n<p>The fastest, most cost-effective, and the least risky way to resolve issues in an Oracle database is to tune the application <a aria-label=\"SQL (opens in a new tab)\" rel=\"noreferrer noopener\" class=\"rank-math-link\" href=\"https:\/\/www.bridge-global.com\/blog\/sql-query-writing-best-practices\/\" target=\"_blank\">SQL<\/a> to use the proper query plan. Here are a few tips for effective Oracle development.<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Identify and target the SQL running from the problem only from the user\u2019s perspective. For instance, if a user sends you a complaint along the lines of \u201dWhen I open my accounts payable inquiry form, it takes 35 seconds to open; this needs to be 2 seconds\u201d, strive to define the problem.<\/li><li>Trace and measure specific database sessions. Use standard tracing tools to identify the SQL, statistics, wait time cost, and the execution plan.<\/li><li>Target tuning efforts to the specific statements that are consuming the most substantial response time for a particular function.<\/li><\/ul>\n\n\n\n<div class=\"wp-block-group\"><div class=\"wp-block-group__inner-container is-layout-flow wp-block-group-is-layout-flow\">\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.bridge-global.com\/blog\/wp-content\/uploads\/2020\/10\/Tuning-inefficient-SQLs-for-better-Oracle-database-performance.jpg\" alt=\"Tune inefficient SQLs for better Oracle database performance\" class=\"wp-image-45751\" width=\"420\" height=\"420\" srcset=\"https:\/\/www.bridge-global.com\/blog\/wp-content\/uploads\/2020\/10\/Tuning-inefficient-SQLs-for-better-Oracle-database-performance.jpg 450w, https:\/\/www.bridge-global.com\/blog\/wp-content\/uploads\/2020\/10\/Tuning-inefficient-SQLs-for-better-Oracle-database-performance-300x300.jpg 300w, https:\/\/www.bridge-global.com\/blog\/wp-content\/uploads\/2020\/10\/Tuning-inefficient-SQLs-for-better-Oracle-database-performance-150x150.jpg 150w, https:\/\/www.bridge-global.com\/blog\/wp-content\/uploads\/2020\/10\/Tuning-inefficient-SQLs-for-better-Oracle-database-performance-45x45.jpg 45w\" sizes=\"auto, (max-width: 420px) 100vw, 420px\" \/><figcaption>Tune inefficient SQLs for better Oracle database performance <\/figcaption><\/figure><\/div>\n\n\n\n<p>Correctly defining and measuring system performance problems before you attempt to address the issue is the best approach.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. Improve storage performance<\/h3>\n\n\n\n<p>Have you exhausted all SQL tuning opportunities? There is still one option. Consider the storage platform on which the database runs. One of the most cost-effective ways to remove bottlenecks is to review storage options for your <a href=\"https:\/\/www.oracle.com\/database\/\" class=\"rank-math-link\" target=\"_blank\" rel=\"noopener\">Oracle database<\/a> server. For instance, if you go for flash storage technology, it can offer significantly higher bandwidth and reduced latency to IO-bound workloads.<\/p>\n\n\n\n<p>The targeted provisioning of flash storage for an Oracle database can provide significant performance improvements without having to refresh your entire database infrastructure. Place specific database objects on flash storage that have the most performance benefit and leave the remainder of the database in conventional storage.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4. Provide a dedicated database infrastructure<\/h3>\n\n\n\n<p>There are many instances where regardless of the tuning efforts applied, reduced system performance results from other systems on a common infrastructure platform. One of the most effective and efficient ways to overcome this issue is to isolate the Oracle database on a dedicated infrastructure. This will ensure a more predictable performance for database workloads, simplified management, monitoring and security.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">5. Utilize an automatic workload repository as an Oracle monitoring tool<\/h3>\n\n\n\n<p>An <a href=\"https:\/\/docs.oracle.com\/database\/121\/RACAD\/GUID-C3CD2DCE-38BD-46BA-BC32-7A28CAC9A7FD.htm#RACAD951\" target=\"_blank\" aria-label=\"Automated Workload Repository (AWR) (opens in a new tab)\" rel=\"noreferrer noopener nofollow\" class=\"rank-math-link\">Automated Workload Repository (AWR)<\/a> is one of the most useful Oracle database performance tuning features that collects, processes and maintains performance statistics. The AWR offers a routine glimpse into the health of your database. You can efficiently utilize the ADDM (Automatic Database Diagnostic Monitor) to provide actionable insights on the information collected by AWR. If you use both tools, you will enhance your performance tuning abilities and save money in the process.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">6. Ensure an optimum level of CPU utilization<\/h3>\n\n\n\n<p>When Oracle\u2019s automatic diagnostic features are not suitable for the problem at hand, there might be a need to undertake manual processes for performance tuning. Always ensure that all your CPU is being utilized when investigating any performance issues of this nature. Checking CPU utilization in the user space will verify if there are any non-database tasks consuming CPU on the systems, limiting the number of shared CPU resources.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">7. Improve Oracle monitoring via SQL tuning<\/h3>\n\n\n\n<p>SQL is considered a messaging language because queries are issued and data is returned. However, there is the chance of client tools generating inefficient SQL statements and poorly written SQL. This can negatively impact Oracle database performance.<\/p>\n\n\n\n<p>These techniques help in monitoring your Oracle database and improve its performance.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><br \/><\/h3>\n<\/div><\/div>\n\n\n\n<p><\/p>\n<!-- AddThis Advanced Settings generic via filter on the_content --><!-- AddThis Share Buttons generic via filter on the_content -->","protected":false},"excerpt":{"rendered":"<p>A comprehensive guide on how to get the most of your Oracle database efforts and keep your environment fully operational and thereby improve your Oracle database performance.<br \/>\n<!-- AddThis Advanced Settings generic via filter on get_the_excerpt --><!-- AddThis Share Buttons generic via filter on get_the_excerpt --><\/p>\n","protected":false},"author":137,"featured_media":45750,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[6,317],"tags":[318],"class_list":["post-45736","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-technology","category-technology-tips","tag-oracle-database-performance"],"featured_image_src":"https:\/\/www.bridge-global.com\/blog\/wp-content\/uploads\/2020\/10\/7-Top-Tips-to-Improve-Oracle-Database-Performance.jpg","author_info":{"display_name":"Praveen","author_link":"https:\/\/www.bridge-global.com\/blog\/author\/praveen\/"},"_links":{"self":[{"href":"https:\/\/www.bridge-global.com\/blog\/wp-json\/wp\/v2\/posts\/45736","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.bridge-global.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.bridge-global.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.bridge-global.com\/blog\/wp-json\/wp\/v2\/users\/137"}],"replies":[{"embeddable":true,"href":"https:\/\/www.bridge-global.com\/blog\/wp-json\/wp\/v2\/comments?post=45736"}],"version-history":[{"count":23,"href":"https:\/\/www.bridge-global.com\/blog\/wp-json\/wp\/v2\/posts\/45736\/revisions"}],"predecessor-version":[{"id":47515,"href":"https:\/\/www.bridge-global.com\/blog\/wp-json\/wp\/v2\/posts\/45736\/revisions\/47515"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.bridge-global.com\/blog\/wp-json\/wp\/v2\/media\/45750"}],"wp:attachment":[{"href":"https:\/\/www.bridge-global.com\/blog\/wp-json\/wp\/v2\/media?parent=45736"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.bridge-global.com\/blog\/wp-json\/wp\/v2\/categories?post=45736"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.bridge-global.com\/blog\/wp-json\/wp\/v2\/tags?post=45736"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
