Informatica installation - the prerequisites
Please be careful while you are doing the installation, as any issues with the minimum sys-
tem requirement might hamper the Informatica PowerCenter installation process and you
might have to initiate the complete installation again.
The following points show some pre-checks that you need to do before initiating the in-
stallation:
•
Operating system
: Informatica PowerCenter can be installed on Windows-based
operating systems or UNIX-based operating systems. Informatica releases different
versions of software for different UNIX-based operating systems. For all Windows
operating systems, we have a common installable. In this topic, we will refer to the
Windows operating system.
•
Database
: Informatica PowerCenter requires a database for configuration. Make
sure you have installed a database (Oracle, Microsoft SQL Server, or DB2). In this
topic, we will refer to Oracle as a database.
The installation process requires two different database users. Please make sure
you create two database users with all the admin privileges. In this topic, we are
using
SYSTEM
as one user and
HR
as the other user.
•
System requirements
: We need to check the system capabilities before we pro-
ceed with the installation. Informatica recommends 4 GB of RAM for the installa-
tion, but practically even 1 GB of RAM works well. The difference shows up in
the processing, but it won't hamper the installation process.
Also, hard disk space of approximately 25 GB will be required.
Before downloading the Informatica software, please check whether your machine
is 32-bit or 64-bit. Also, make sure you install the correct database with 32-bit or
64-bit configuration to avoid any installation failure later.
Once you have checked the minimum system requirements, we are all set for the next step
towards installation.
