Task 2: Pre-installation configuration (Linux)
Choose a Portal Server.
For performance reasons, avoid installing the IT Analytics Portal software on the same server as the IT Analytics Data Collectors. Precisely, avoid installing Data Collectors in
/opt/aptare.If for some reason, you require both to be on the same server, ensure that both the Portal and Data Collector software do not reside in the same directory on the server. Portal software installation tasks require root privileges.
For new Portal installations, the minimum server memory requirement is 32 GB. Oracle database requires a minimum of 24 GB of memory. Portal installations will fail if sufficient memory resources are not available on the Portal server.
The Portal Installation software checks the following resources:
Total physical memory (physical + virtual) must be greater than 24 GB, otherwise Oracle will fail to start. Add more physical memory to the Portal server.
Total temporary file system (tmpfs) memory must be 24 GB or greater, otherwise Oracle will fail to start. Increase the size of tmpfs, typically in /etc/fstab.
Shared memory (kernel.shmmax parameter) must be 12 GB or greater, otherwise Oracle will fail to start. Increase the value of the shmmax parameter, typically in /etc/sysctl.conf. After increasing the value for the shmmax parameter, execute: sysctl -p.
Verify the OS of the Portal Server. Check that the OS is one of the certified operating systems listed in the Certified Configurations Guide.
Verify that sufficient disk space exists on the designated Portal Server. For the database file systems, the amount specified is the minimum to create the database. The database grows in size over the period of time. The growth of database dependents on various factors such as subsystems from which data is collected, type of systems collecting data from, retention periods for data(which is configurable), and so on.

If you plan to export or email reports as PDF files, to ensure proper rendering of these output formats, a graphics manager such as X Virtual Frame Buffer (Xvfb) is required. Contact your IT organization to configure this capability.
Verify whether rng-tools, fontconfig, ss, and nest are installed. Either ss or netstat must be installed .
Verify that the necessary rpms exist on your system based on the OS.
For RHEL 8, use the following command:
The command returns:
For RHEL 7 and CENTOS 7, use the following command:
The command returns:
For SUSE 12 Linux Enterprise, use the following command:
The command returns:
Verify that the bc command is available, as it is required by the database installer.
Download the application binaries for both the Oracle Database Installer and the Portal Installer from www.veritas.com. Use the instructions provided in the confirmation of your purchase agreement.
Troubleshooting User Account Creation: The Portal installation process will create user accounts for aptare and tomcat. If you are using non-local user management (such as LDAP or NIS) to manage the Linux user accounts, the useradd command may fail to execute successfully. Take the following steps to manually pre-create the required users:
Using your normal process for creating user accounts in LDAP, pre-create the user accounts aptare and tomcat with home directories under /home.
User ID
Primary Group
Supplementary Groups
aptare
aptare
dba
tomcat
tomcat
aptare
Some environments, particularly virtualized ones using automount, will fail to create the home directories when the useradd command is used. In this situation, manually create the /home/aptare and /home/tomcat directories and chown them to aptare and tomcat respectively.
If you need additional clarification, contact the Cohesity Support for details.
Troubleshooting script issues: A known issue associated with Security Enhanced Linux (SELinux) may arise when executing scripts that require Java. This results in a permission denied error message. To resolve this issue, configure SELinux to allow the use of shared libraries with text relocation.
The installer expects the SELinux configuration to be either disabled or permissive.
Ensure ports 80/tcp, 8011, and 8017 are open in the firewall for proper functioning of the portal.
