Last Updated:

Applies to

  • OnCommand Insight (OCI) 7.3.x
  • Red Hat Enterprise Linux (RHEL) or CentOS


  • This article describes how to identify and manually set memory allocation for OCI components.
  • Component memory allocation may require adjustment in the following scenarios:
    • The amount of system memory (RAM) on the server hosting the application has changed since the application was installed.
    • NetApp has made recommendation for a specific environment.
  • OCI determines component memory allocation at the time of install based on the table below.
