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 ( > > > tab > > tab > click ) [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]
