The initial configuration and system installation stage plays a critical role in ensuring its successful operation and development. This stage determines how "smooth" the implementation will be. Errors made at this stage may lead to unpredictable cost increases in the future.

LEAVES company has extensive experience in performing the above tasks for various platforms and software products, and also in analyzing and defining requirements for successful installation and quickly finding solutions to technical and organisational problems.

To achieve this, both well-known standards such as Oracle OFA and LEAVES own solutions are used, including building the system model and calculation of its basic parameters.

Upgrade to New Versions and Migration

Upgrades to new versions of the system and software products requires thorough analysis and clear planning. In most cases, the upgrade is carried out while on the "live" system, which may lead to disastrous consequences.

Based on the experience and recommendations of software and hardware suppliers, the company's professionals thoroughly plan the upgrade process and test the deliverable, taking account of a wide range of compatibility parameters and specific aspects of the application implementation.

Given importance of this stage, LEAVES company has a developed a capability to model the upgrade process and carry out preliminary tests of the entire system or its elements.

Integration and Interface Tuning

Any information system comprises a lot of heterogeneous components, and one of the most complex tasks is to ensure their joint operation. Often, it is lack of this integration that leads to serious deterioration of the system's reliability and performance.

The company uses various optimization techniques that are aimed not just at improving performance, but are designed to maintain specified performance during a long period. To achieve this, a wide range of methods for analysis of the system's "bottlenecks" are used (see "Analysis of the system's bottlenecks"), performance forecasting methods and various software products.

Audit and Analysis

When actual systems are operated, numerous issues and problems arise that can not be possibly solved once and for all.

What kinds of problems exist, which of them may have critical consequences, how much time and money will it take to solve them, what will be delivered - these questions, whether related to the entire system or its individual components, can be answered by skilled and experienced staff of LEAVES company.

Database Server Performance Tuning

Performance is one of the key factors contributing to the successful operation of the system. In many cases, underestimating its importance eventually renders the entire system inoperable.

Implementing performance improvements requires extremely high skills. However, the results will usually far exceed the costs incurred in the process.

Data Backup and Recovery Strategy

Creation of a reliable production system is a complex task that may involve, among other things, high cost.

When implementing measures to enhance reliability of the system, special emphasis is made on the process of identifying actual reliability requirements (downtime, frequency of failures, routine maintenance schedule, staff's skills) and selecting appropriate technical and organisation solutions to minimize potential costs.

Combination of various Oracle tools and a wide range of software and hardware products developed by other suppliers allows LEAVES company to ensure the required reliability level for production systems of any class.

Training and Support of DBAs and Developers

When the system is operated, technical problems arise quite frequently, and these, unless solved in a timely manner, may lead to serious losses.

Advice provided by LEAVES consultants not only allows you to solve these problems quickly but also prevents them from happening. The major benefit of this cooperation between LEAVES professionals and Clients' DBAs is that it enables the latter to quickly develop the necessary skills. Where necessary, training or detailed advice of the widest range of issues can be provided.
