Performance Tuning

Any drag in system response gets noticed immediately by end-users and customers using your databases and applications. Aarisha Inc. consultants has the expertise to quickly and reliable identify the root cause of the performance issue, be it hardware, OS, network, database or application. We specialize in both proactive and reactive tuning. Our performance tuning efforts have yielded faster code execution by reducing execution time from hours into minutes and seconds

We provide various tuning services including the followings:

  • Oracle Server Tuning
  • Oracle RAC Tuning
  • Oracle Data guard tuninig
  • Oracle Streams Tuning
  • SQL Server Instance and Database Tuning
  • IBM DB2 Instance and Database Tuning
  • Application Tuning
  • Webcenter
  • Webcenter content
  • OID
  • Oracle Access Manager

Performance tuning helps you get the maximum value out of your databases and your entire IT infrastructure. There are many ways to improve performance, including optimizing your database and operating system configuration and rewriting queries or entire data processing workflows. It’s knowing which ones to use, in which systems that’s critical. Aarisha Inc. data experts understand all areas of performance tuning and use the best tools available in each database to make sure your infrastructure operates at peak capability. With Aarisha’s managed data services, performance tuning is not a one-time event. We continuously monitor your critical workloads and service level agreements to make sure your queries perform consistently as data volumes grow. We can respond to performance issues before you’re even aware of them. With each database change or upgrade, we examine the possible impact on performance and determine the best action plan to ensure your business continues to thrive.

Database Performance Tuning

Performance tuning is a challenge for most DBAs. It is also one of the more time-intensive aspects of a DBA’s job. If your DBA is reviewing user complaints of slow performance or batch jobs taking longer to complete, then we can help.

Performance tuning focuses primarily on writing efficient SQL, allocating appropriate computing resources, and analyzing wait events and contention in the system. Aarisha consultants can help improve user experience by quickly analyzing and tuning performance issues. We have a large number of satisfied customers who have come to us with complex tuning requirements which we completed within estimated time and budget limits. Our tuning methodology will provide quick results and free up your DBAs for other initiatives.

Our proactive approach of setting up Oracle scripts with thresholds for key I/O, CPU, and memory usage metrics helps us identify hotspots and trouble areas. This data allows us to rapidly resolve tuning issues. Our approach focuses on conducting a top-down review, analyzing the server, instance, objects, and SQL statements. Aarisha is experienced in instance tuning and setting appropriate database engine parameter values to maximize performance. Based on the current I/O and workload profile we can advise on redistributing related objects on tablespaces and drives, helping avoid hotspots on indexes and tables.

Ensuring that the performance of your Oracle applications are configured to reach peak efficiency has a direct effect on how your business interacts with both customers and suppliers. This is why Oracle Performance Tuning is a critical service and why we recommend it is carried out at least on a quarterly basis.

A common mistake when performance tuning an Oracle application is to only look at a single area of the Oracle environment. We ensure that the databases, servers, storage devices and switches are also performing as they should.

Performance Tuning Oracle applications is a highly a skilled and an ongoing task with best results coming from skilled DBA's with years of experience, this is why it's always cost effective to outsource this service to an Oracle Partner who offers it as a key service.

Middleware Performance Tuning

Response time is basically sum of process time and wait time. All process spend most of their time waiting for a resources to get released. Resources such as memory, database-connections, etc. To improve performance, we should reduce the overall wait time. One primary resource is database connections. One way to reuse and manage database connections is to use the JNDI and connections pools properly. Connection Pools are connections that are reserved by the application server to a database and thereby reduces the time to wait for a new connections to be made to the database. One good practice to ensure that you always use the jndi is, when you use a database adapter in your BPEL do not enter the database connection information in the WSDL (apart from your jndi name). If you enter the database connection information and your jndi information, it will default to the connection parameters if your jndi is invalid. You should also manage the Database Connection Timeouts and inactivity connection timeout to manage the database connections in the connection pool.

Use of Introscope as a tool for middleware performance tuning

Introscope provides an overview of application and server health and statistics. New in this release is increased scalability, ease of administration, key transaction detection, and new alerting capabilities. Introscope provides a manager clustering capability, so that a single administration interface can be used to manage the entire monitoring cluster, providing the capability to monitor as many servers and applications as a given enterprise needs. It also performs automatic baselining of applications, so that boundary conditions can be detected and alerts issued without interference from a production support staff. An interface API allows Introscope to pull data from any custom monitor source, allowing enterprises to build their own monitoring conditions. Introscope supports all majour JVMs and platforms, and the impact of monitoring on performance is negligible.

Introscope allows the entire enterprise to leverage the expertise of the IT organization. Its out-of-the-box reporting capability enables users to create reports on the fly, so that business-critical intelligence can be delivered quickly and effectively to thosewho need it.

Introscope gives you everything you need to manage the performance of your unique environment. Its completely customizable interface integrates seamlessly with pre-defined operations procedures and enhances the problem identification process, allowing operations personnel to identify and triage application performance issues regardless of their level of Java expertise.The built-in SmartTrigger™ alert system also integrates event notification with existing frameworks via e-mail, SNMP traps and native APIs or messages, making production monitoring easy.

Security functionality allows Introscope administrators to define user roles by selectively enabling or disabling specific functions, giving them fine-grained control over Introscope usage. Introscope also allows enterprises to leverage the organization’s existing investment in its enterprise security architecture through direct integration with LDAP servers.
