Database Error Messages

AMM is defined in the initialization file using the MEMORY_TARGET parameter. While trying to enable AMM, the database encountered an error. Either the operating system does not support AMM or it is not configured correctly.

Refer to Oracle Database documentation to verify if the operating system supports AMM. If not, remove AMM related parameters from the initialization file. On Linux, check if /dev/shm is mounted and whether it can accommodate the memory requirements defined by MEMORY_TARGET. The database alert log contains additional information about the use of /dev/shm on the Linux platform as well as more actionable steps.

The MEMORY_TARGET parameter was not supported on this operating system or /dev/shm was not sized correctly on Linux.

Refer to documentation for a list of supported operating systems. Or, size /dev/shm to be at least the SGA_MAX_SIZE on each Oracle instance running on the system.
