5. DEMONSTRATED EXCELLENCE
Migration and
upgradation
 Actively involved in migration of FOIS database from Oracle 11g on
HPUX itanium to oracle 12c on exadata without oracle team support.
Backup and recovery
 Created a database and tested all possible recovery scenarios of
Database using RMAN .
Configuration and
administration
 Worked and resolved issues in association with Oracle for database
and OEM grid control.
Application Versions
release
 Helped and assisted AD team members time to time for various
application version release.
Support
 Provided consultancy to team members from time to time in
architecture & performance issues related to oracle database.
 We work round the clock, so provide 24*7 Support to DBA team.

highly available and high performance system”

8. Highly available and High performance system
• High availability, or HA, is a label
applied to systems that can operate
continuously and dependably without
failing. These systems are extensively
tested and have redundant
components to ensure high quality
operational performance. In short,
high availability systems will be
available no matter what occurs.
• Performance means system
throughput under a given workload for
a specific timeframe. Performance is
validated by testing the scalability and
the reliability of hardware, software
and network. It is an ongoing process
and not an end result.
What is high available and high
performance system ?
8

9. Highly available and High performance system
FORMULA
x = (n – y) * 100/n
Where n is the total number of minutes in a
calendar month and y is the total number of
minutes that service is unavailable in the given
calendar month.
Availability can be measured
as the percentage of time
that systems are available.
How is availability measured?
Factors Affecting HA
Ensuring that apps hosted in the middle tier remain up and running requires database failover mechanism
that directs queries to another server with a copy of the same data. To deliver availability during a
database failover you must ensure that:
• The same components should be deployed to every instance in the cluster.
• Your failover mechanism should be aware of the availability of nodes in a given cluster along with their
location.
• The failover mechanism should also track the progress of all the tasks so as to ensure a roll back when a
given operation has failed.

10. Solution for Optimizing IT administrative effort for highly available and high performance system
Database Scaling – Horizontal vs. Vertical
Vertical Scaling
You can scale your database vertically by
allocating additional resources (CPU, memory,
storage) which will give you immediate
performance benefits and allow you to process
more transactions.
Horizontal Scaling
If you want to handle more user requests or
process an increased workload which is beyond
the capabilities of a single database instance,
you can leverage the benefits of scaling out
your database instances by
implementing horizontal scaling.

11. Solution for Optimizing IT administrative effort for highly available and high performance system
Database Read Replicas
A read replica is just a read-only copy of
your database, and each replicated
instance has the full set of data. From an
application perspective, the database
queries can now be routed to the read
replicas which results in enhanced
performance.
11
Database Caching
An effective caching strategy can help to
improve your application performance
and reliability by reducing the overhead
on the database while optimizing for cost.
You can keep the frequently accessed
data in an in-memory cache and save the
roundtrip to database.

Database Sharding
Sharding can be defined as partitioning of
data across servers to meet the high
scalable needs of the modern-day
distributed systems so that you can
manage data volume efficiently.
Database Design in a Microservice
Architecture
When you are designing your services, it
is important to have each individual
microservice have its own separate
database. This will enable you to deploy
and scale your microservices
independently.
