Oracle installation guide to maintain high availability Oracle database server to support 24/7 running database.

1. Oracle Installation Guide for High
Availability Environment Database Server
There are lots of prerequisites of installation high availability Oracle server. You
should need to consider performance, recovery and manageability of Oracle
server in installation phase.
Installation and configuration Oracle has introduced a number of challenges. This
is a new facility, some of these challenges, such as calculating disk space, the
exposure of data files, the choice of operating system and database block sizes,
and determine the maximum number of files data, require decisions about the
parameters that are appropriate for your environment. Even before I had the
opportunity to use their database and find relevant information. The seriousness
of making the right decisions is growing with high availability requirements,
where the impact of a wrong decision is much more serious because these
decisions are binding throughout the life of the database. Fixed a bad decision
and involves a long time without rarely tolerated. Installation and configuration is
very critical from the perspective of high availability, since they constitute the
basis for all adjustments and perform routine maintenance.
At most sites with high availability, data-takes a back seat availability, recovery
and maintenance. Their enthusiasm is to determine the high availability and
sustainability of the site, however, sometimes DBAS Database nearly useless in
terms of performance. This means that the main results of the inspections and
corrective measures can be implemented when downtime and defeat the whole
purpose to ignore the performance targets installation and configuration. Instead
of focusing solely on availability and downtime due because of such short-

important as performance, usability, and better maintenance. In specific cases
where the performance targets in direct conflict with availability, it is reasonable
to allow the latter to win.
So how DBAs tend to do things right the first time? How can they ever managed
to get everything set up and works well "out of the box"? The bad news is they
cannot! High availability uptime can be achieved simply by installing a vanilla. It
can only be achieved by following a combination of Oracle and good
recommendations to improve these practices based on DBA experience in similar
environments.
But, unfortunately, the Oracle DBA is ignoring the recommendations during the
installation process of Oracle. After the installation process, the database will not
be affected by performance issues, but when at times, some mysterious
performance issues, which are not easily understood. All of these performance
issues to present a false choice of the basic parameters of the installation of the
Oracle database. Take for example the selection of parameters DB_BLOCK_SIZE
wrong during installation, the database storage of information, database systems,
or DSS. Changing this parameter requires a long period of inactivity, it is necessary
to re-build a database from scratch.
