Portal Installation Memory Requirements

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. [Windows and Linux OS]

  • Windows Virtual Memory must be 24 GB or greater, otherwise Oracle will fail to start. Increase the size of the virual memory if required (Windows > System > Advanced System Settings > Advanced tab > Settings > Advanced tab > click Change) [Windows Only]

  • 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. [Linux OS only]

  • 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 [Linux OS only]

  • Swap space of minimum 16 GB must be created. [Linux OS only]
