Oracle Database Performance Tuning

Poor SQL statement performance and high CPU usage on your Oracle database server can cripple your business operations that depend on quick and reliable data access. Slow SQL processing almost always indicates the need for performance tuning. We will analyze your pain points and make recommendations on your Oracle database configuration, memory settings and storage architecture. We will also analyze poor performing SQL statements that may benefit from the correct index, syntax and optimizer settings. Our DBA engineers use Oracle’s performance monitoring and reporting utilities (AWR, ASH, etc.) to determine what resource bottlenecks are negatively affecting performance. We can analyze specific problems or conduct a complete Health Check for your Oracle database.

Oracle Database Memory Usage

The Oracle database management system is the most flexible and sophisticated. Its ability to provide performance views for memory management components of the database is an invaluable tool, especially for managing DSS systems. With it, Xtivia DBA’s can more easily ensure that all the settings for Oracle memory utilization are optimal for their applications. Allocating memory on your Oracle database server requires an initial analysis of available memory resources to arrive at realistic targets. We can make recommendations on how to divide your available memory into the buffers where the Oracle database will employ it best. We’ll consider and analyze memory buffer requirements like the system global area, shared pool, JAVA pool, large pool and process global area.

Oracle Database Server Architecture RAC and Streams

Is your server configured to support optimal performance? Have you considered using Oracle Streams for distributed processing or Oracle Real Application Clusters for parallel processing? How many engines are available and is the current number of online engines producing the best result? Our assessment can show you where improvements in your server configuration such as memory, engine, network and other configuration options can make your server perform optimally for the lifecycle of your system.

Oracle Database Migration from 32-bit to 64-bit

Are you ready to get out from under the 32-bit memory limits for Oracle? If you are planning a version upgrade or just want to take advantage of your 64-bit AIX, HP-UX, Solaris, Linux or Microsoft Windows operating system, we can help you. We’ll upgrade your Oracle instance to take advantage 64-bit architecture available on Linux, UNIX and Windows.

Oracle Database Critical Patches Updates

A Critical Patch Update is a collection of patches for multiple security vulnerabilities. It also includes non-security fixes that are required (because of interdependencies) by those security patches. Critical Patch Updates are cumulative, but each advisory describes only the security fixes added since the previous Critical Patch Update. So, prior Critical Patch Update advisories should be reviewed for information regarding earlier accumulated security fixes. Due to the threat posed by a successful attack, Oracle strongly recommends that customers apply fixes as soon as possible. Xtivia DBAs can assist you in understanding which Critical Patch Updates you need and then help with the planning and application of those patches to your Oracle environment.

Oracle Database Health Check

Do you question if you are getting the most out of your Oracle database running on AIX, HP-UX, Solaris, Linux or Microsoft Windows? Our Oracle RDBMS Health Check service will help you find out. We’ll perform a deep analysis of your database workload, environment, database configuration and resource intensive code to provide you an easy-to-read, management-level report with the current state of your system and any recommendations to improve its performance and availability.

Oracle Database Troubleshooting Errors

Are your users encountering errors when using your Oracle database? Xtivia certified Oracle DBA engineers will help you determine if the errors are server critical or informational. We’ll find the cause of the problem and fix it. We’ll quickly have your systems back to normal.

Oracle Database Security and User Access

We can help you reduce the cost of protecting data by using Oracle’s many layers of security to insure data protection against unauthorized access and corruption. Regulations such as Payment Card Industry (PCI) Data Security Standard (DSS), Health Insurance Portability and Accountability Act (HIPAA), Sarbanes-Oxley (SOX), Gramm-Leach-Bliley Act (GLBA) and global regulations call for separation of duties and other preventive measures to ensure data privacy and data integrity.

Oracle Database Vault helps you address the most difficult security problems remaining today: protecting against insider threats, meeting regulatory compliance requirements and enforcing separation of duty. It provides a number of flexible features that can be used to apply fine-grained access control to your sensitive data. It hardens your Oracle Database instance and enforces industry standard best practices in terms of separating duties from traditionally powerful users. Most importantly, it protects your data from super-privileged users but still allows them to maintain your Oracle Databases. Oracle Database Vault can become an integral component of your enterprise.

Let our certified Oracle DBA engineers help you create, prepare, implement and monitor a security plan that will ensure the integrity of your data no matter what the threat.

Oracle Database Auditing

Have you ever thought of utilizing Oracle database auditing to detect penetration of the system and misuse of the resources? Xtivia certified Oracle DBA engineers can assess your business needs, plan and install the audit system, configure auditing options, set up audit trails and threshold procedures and process the audit data.

Oracle Replication – Streams, Data Guard, and RAC

Xtivia’s Certified Oracle DBA engineers have vast experience managing Oracle Replication from 8i to 11g and handling various types of Oracle Replication including Streams, Advanced Replication, Data Guard and Oracle Real Application Clusters (RAC).

Data availability is an important factor to the success of any business. In a distributed environment, Oracle Streams improves data availability and accessibility by sharing and replicating information to multiple sites quickly and reliably. Oracle Streams was introduced in Oracle 9i and is used to perform data replication, data warehouse transformation and messaging.

Created as a disaster recovery solution, Oracle Data Guard is also a solution for High Availability. It can be used to replicate and maintain production databases to alleviate reporting job traffic on the server. Data Guard can be configured for real-time consistency between the production database and from one to as many as nine standby databases or, delayed by a set time to allow the standby to become a snapshot standby. Data Guard is especially useful for testing and rolling upgrades and can be configured as either a physical (Redo-Apply) or logical (SQL-Apply). Each has its advantages and inherent flexibility.

Oracle Real Application Clusters (RAC) is an option of Oracle Databases. Oracle RAC is a cluster database with a shared cache architecture that overcomes the limitations of traditional shared-nothing and shared-disk approaches to provide highly scalable and available database solutions for all business applications. Oracle RAC is a key component of Oracle enterprise grid architecture. Most Oracle RAC users employ a two node cluster to insure always available service to its user community. The two node configuration offers the flexibility needed to perform maintenance, upgrades and patching without interfering with user activity.

Oracle Backup and Recovery

Does your backup strategy match your business needs? Are you backing up frequently enough to prevent a large data loss? We can help you design a backup and recovery strategy that matches your data protection needs while providing recovery with minimum downtime. Xtivia can assist with the implementation of your backup and recovery strategy using various methods including Export/Import, Cold or Off-line Backups, Hot or On-line, and Recovery Manager (RMAN). You may need to use more than one of these backup methods. Does your organization also backup all required parameter files, software libraries, password files, etc? Your business may also need to backup archived log files if your database is in ARCHIVELOG mode. Our certified  DBAs can help you answer all of these questions and work with you to design, plan, implement and test all the backup and recovery strategies you need to have in place.
