Installing ITA 9.0.6 or 9.0.7 on RHEL 7? Go here
Installation requirements
We usually don't offer support on Red Hat installations as most of our customers who use RHEL have their own ways of installing and configuring it.
Prerequisite: Before starting the ITA installation procedure, make sure that the general system requirements for on-premise installations are fulfilled in addition to these:
- A server running RHEL 8.0 with at least minimum install selected.
IMPORTANT: Installing ITA 9.1.0 on a Red Hat system is not supported. -
Access to RHEL packages by using an active RHEL subscription
- Disk space:
/data
is used for indexes and ETL configuration. Minimum size 5 GB./data/backup
is used for backups. Minimum size 50 GB. Backups should always be mounted on a remote network share./opt/jboss-as
is used for the application server. Minimum size 10 GB./var/lib/pgsql
is used for the postgres database. Minimum size 30 GB./var/log
is used for log files. Minimum size 5 GB./tmp
is temporarily used for backup file creation and/or backup file restore job. It can also be temporarily used for server/ITA upgrade.
IMPORTANT: This directory must be large enough to contain unpacked backup and server upgrade file(s). Calculate the minimum size as backup file size x 4 + 3 GB.
- Total amount of space recommended for an installation is at least 100 GB in addition to the operating system.
Changes to the system
The following system changes are applied during installation of the IT Advisor software.
- ITA will install the listed packages* if not already installed.

As mentioned on this article, "You can get a list of dependent packages for Red Hat Enterprise Linux installation through your local Schneider Electric contact". - We need this list. Can it be published on the help center? OR responded via Email?
Hi ANIRUDDHA DESHMUKH,
