Database Administration Services
We provide Database Administration
services including Installation & Configuration of
Databases, Security, Network Administration, Performance
Tuning, Backup & Recovery Stratagies. In addition to the
Administrative Services, we do Analysis, Design and
Development of databases.
Performance Tuning
We provide services on Performance
Tuning of databases. We specialize on the following areas
while tuning the databases:
I/O Tuning
First, We will study the availability
of hardware resources and the Database objects which the
application(s) are accessing. Basing on the study, We will
identify the frequently accessed and high volume transactional
Tables and it's Indexes. These objects will be bifurcated and
attached to different Tablespaces. The Containers/Data Files
of the respective Tablespaces will be kept in different disks.
With this the I/O will be distributed across number of disks
and the performance will be improved when we compare all the
tablespaces in a single disk.
Memory Tuning
If the Cache hit ratio is high, the
applications will be faster. For this memory tuning is
required. Basing on the available memory, the memory tuning
will be done. We will use our techniques depends on the
database and try to see the cache hit ratio will be more.
Application Tuning
Application tuning is the most
important part of tuning. We know the affect of a poorly
written SQL statement. We will analyse the existing SQL
Statements and verify the execution timings. We will give
suggestions for modifications of SQL Statements.
Data Replication and Back up
Services
Data Replication
We are familiar with replication
services. Creating and managing duplicate versions of a
database is called as data replication and it not only copies
a database but also synchronizes a set of replicas so that
changes made to one replica are reflected in all the others.
For companies located in different locations and need to work
with the same database which resides at a remote location to
the work location can opt for data replication. The beauty of
replication is that it enables many users to work with their
own local copy of a database but have the database updated as
if they were working on a single, centralized database. For
database applications where users are geographically widely
distributed, replication is often the most efficient method of
database access. This replication can be achived in differnet
mechanisms according to the requirement of the company and the
RDBMS existing in the company.
Backup Services
As data is one of the most important
asset and under any critical circumstances not even a single
byte of data should not be lost, we as a part of IT Servies
offer Backup Services for your organisation basing on your
business requirements. We offer cold(off-line) and
hot(on-line) backups according to the requirement of your
company. We promise for 100% backup and recovery for your
data(database) at any point of time. Even while taking a hot
backup we do not disturb the availability of your database
even to the end users.
Data Migration
We will provide services for Data
Migration. In present days, companies are seeking for
well-managed storage systems. Data classification is very
important which describes conditions for data access,
retention requirements etc. Keeping heavy volume of unused
data in the database is expensive with respect to space and
performance. Also, Data migration is necessary when an
organization decides to use a new computing systems or
database management system that is incompatible with the
current system. Typically, data migration is performed by a
set of customized programs or scripts that automatically
transfer the data. For this we require data migration from One
database to another or to a file system. We are expertise in
migrating the data from database by useing the database
utilities Export,Import,Load, SQL Loader,DTS etc..
