Verify System Requirements
Verify that your planned domain meets the minimum system requirements for the installation process, temporary disk space, port availability, databases, and application service hardware.
For more information about product requirements and supported platforms, see the Product Availability Matrix on Informatica Network:
https://network.informatica.com/community/informatica-network/product-availability-matricesVerify Temporary Disk Space Requirements
The installer writes temporary files to the hard disk. Verify that you have enough available disk space on the machine to support the installation. When the installation completes, the installer deletes the temporary files and releases the disk space.
The installer requires 8 GB of temporary disk space.
Verify Port Requirements
The installer sets up the ports for components in the Informatica domain, and it designates a range of dynamic ports to use for some application services.
Verify Services Installation Requirements
Verify that your machine meets the minimum system requirements to install the Enterprise Information Catalog services.
The system requirements differ based on the following conditions:
- If the Informatica Domain and Hadoop cluster are on the same machine
- The minimum memory requirement for the Linux operation system is 32 GB RAM. The minimum disk space required is 100 GB.
- If the Informatica Domain and Hadoop cluster are on different machines
- The minimum memory requirement for the Linux operation system is 16 GB RAM. The minimum disk space required is 60 GB.
Prepare Databases for the Informatica Domain Overview
Before you create the domain and the application services, set up the databases and database user accounts for the repositories.
Set up a database and user account for the following repositories:
- •Domain configuration repository
- •Data object cache repository
- •Model repository
- •Profiling warehouse
- •Reference data warehouse
To prepare the databases, verify the database requirements and set up the database. The database requirements depend on the application services that you create in the domain and the number of data integration objects that you build and store in the repositories.
See the
Informatica Big Data Suite Installation and Configuration Guide for more information about configuring databases for repositories.
Preparing the Internal Hadoop Cluster Environment
You need to perform multiple validation checks before you can before you install Enterprise Information Catalog on an internal Hadoop cluster.
Perform the following steps before you install Enterprise Information Catalog on an internal Hadoop cluster environment:
- •Configure the /etc/hosts file on each machine so that you have fully qualified domain names. Informatica recommends the following host name format in lowercase: <machine ipaddress> <fully qualified name> <alias>.
Note: To verify the configured host name, run the #hostname -f command.
- •Set up passwordless Secure Shell (SSH) connections between the following components:
- - From Informatica Cluster Service to Hadoop Gateway.
- - From the Hadoop Gateway to Apache Hadoop nodes.
- •Make sure that the /etc/hosts file on the machine that hosts Informatica domain includes entries for all Hadoop hosts.
