The goal of the Oracle Real Application Clusters (RAC) series of Best Practice and Starter Kit notes provides customers with quick knowledge transfer of generic and platform specific best practices for implementing, upgrading and maintaining an Oracle RAC system. This document is compiled and maintained based on Oracle's experience with its global RAC customer base.

This Starter Kit is not meant to replace or supplant the Oracle Documentation set, but rather, it is meant as a supplement to the same. It is imperative that the Oracle Documentation be read, understood, and referenced to provide answers to any questions that may not be clearly addressed by this Starter Kit.

All recommendations should be carefully reviewed by your own operations group and should only be implemented if the potential gain as measured against the associated risk warrants implementation. Risk assessments can only be made with a detailed knowledge of the system, application, and business environment.

As every customer environment is unique, the success of any Oracle Database implementation, including implementations of Oracle RAC, is predicated on a successful test environment. It is thus imperative that any recommendations from this Starter Kit are thoroughly tested and validated using a testing environment that is a replica of the target production environment before being implemented in the production environment to ensure that there is no negative impact associated with the recommendations that are made.

In this post, we look at the 12c (12.2.0.1 the 12.1.0.2) End of Support timeline in Amazon RDS for Oracle, study the version upgrade choices available to you, and dive deep into the best practices to follow during the upgrade process.

In this post, we reviewed the 12c End of Support timeline in Amazon RDS for Oracle, studied the version upgrade choices available to you, and covered the best practices during the phases of the upgrade process.

This article helps you to prepare an Oracle workload to run in Azure and explore the best architecture solutions to provide optimal cloud performance. The data provided by Oracle in the Statspack and even more so in its descendent, the AWR, assists you in developing clear expectations. These expectations include the limits of physical tuning through architecture, the advantages of logical tuning of database code, and the overall database design.

In this compact book, Steven Feuerstein, widely recognized as one of the world's leading experts on the Oracle PL/SQL language, distills his many years of programming, teaching, and writing about PL/SQL into a set of best practices-recommendations for developing successful applications. Covering the latest Oracle release, Oracle Database 11gR2, Feuerstein has rewritten this new edition in the style of his bestselling Oracle PL/SQL Programming. The text is organized in a problem/solution format, and chronicles the programming exploits of developers at a mythical company called My Flimsy Excuse, Inc., as they write code, make mistakes, and learn from those mistakes-and each other.

This book offers practical answers to some of the hardest questions faced by PL/SQL developers, including:

There is often more than one way to write a query that returns the same results, but some methods may perform better than others. In this article, Ben Brumm discusses ten best practice when writing SQL code for Oracle.

I know this is a long-awaited white paper and I would like to get this out into the hands of the public to help those who simply want to know the recommended practices for successfully assessing, sizing, architecting and migrating Oracle onto Azure Infrastructure as a Service (IaaS).

This white paper provides guidance from beginning to end that can be used by any organization to assess an Oracle workload and begin its journey to successfully migrating it to Oracle on Azure IaaS. The goal is to centralize all the recommended practices into one document and yes, it will become a Microsoft document eventually, (we're still in the early stages or redesigning all the Oracle documentation for Microsoft) but the Data Architecture Blog provides me a quick way to get content to customers in a very easy and consumable manner.

It is best to compile the unit tests before running them. Right click on a test suite in the Unit Test Manager and select Compile, or Compile All as shown in Figure 12.

Pure Storage recommends that you use multipath disks to achieve maximum performance and resiliency. If you are using ASM, you need to configure the SCANORDER to look at multipath devices first. You can do this by changing the following setting in /etc/sysconfig/oracleasm.

ASMLib is an Oracle-provided utility that allows you to configure block devices for use with ASM. Specifically, it marks devices as ASM disks and sets their permissions so that the o/s account that runs ASM (typically either grid or oracle) can manipulate these devices. For example, to create an ASM disk named MYASMDISK backed by /dev/dm-2 you would issue the command:

Afterward, /dev/dm-2 appears to still have the same ownership and permissions, but ASMLib creates a file /dev/oracleasm/disks/MYASMDISK owned by the O/S user and the group is identified in /etc/sysconfig/oracleasm. Tell the ASM instance to look for potential disks in this directory through the asm_diskstring initialization parameter.

There is no significant performance penalty for using a file system instead of ASM. As with ASM, we recommend placing data, redo, and the fast recovery area (FRA) onto separate volumes to ease administration. We also recommend using the ext4 file system and mount it with discard and noatime options. Below is a sample /etc/fstab file showing mount points /u01 (for oracle binaries, trace files, etc.), /oradata (for datafiles) and /oraredo (for online redo logs).

The database should be installed on hardware that is equal to or better than the specifications of the best Deep Security Manager node. For the best performance, the database should have 8-16 GB of RAM and fast access to the local or network attached storage. Whenever possible, a database administrator should be consulted on the best configuration of the database server and a maintenance plan should be put in effect.

To improve Deep Security Manager performance, we recommend that you perform regular index maintenance on the Deep Security database to keep it from becoming overly fragmented. Follow your organization's best practices for reindexing databases, or refer to your database vendor's documentation for guidance:

Separate from high availability or load balancing, best practices include regular database backups and a disaster recovery plan. Backups can be used to restore the database if there is a serious failure. See your vendor's documentation and Back up and restore your database.

Add the following entries into the "/etc/security/limits.conf" script or "/etc/security/limits.d/99-grid-oracle-limits.conf" script, where the setting is at least the size of the HugePages allocation in KB (HugePages * Hugepagesize). In this case the value is 306*2048=626688.

MySQL Enterprise Monitor continuously monitors MySQL queries and performance related server metrics. Receive alerts on significant deviations from the baseline performance trends, and best practice Advisors recommend changes to configuration and variable settings to improve performance.

MySQL Enterprise Monitor protects MySQL Servers and helps developers and DBAs discover and address security holes. The Advisors provide a set of rules designed to enforce MySQL security best practices and alert you to potential vulnerabilities before they impact your system. 17dc91bb1f
