    AIK: ORA-00845: "MEMORY_TARGET not supported on this system"

    • Article Type: General
    • Product: Aleph
    • Product Version: 19.01

    Problem Symptoms:
    Error in running AIK: ORA-00845 "MEMORY_TARGET not supported on this system".

    /dev/shm is less than MEMORY_TARGET (or MEMORY_MAX_TARGET):

    There is 4 Gig of memory; more of it needs to be "shared memory" -- so that /dev/shm Available is greater than MEMORY_TARGET.

    Additional Information

    /exlibris/ftp_from_exlibris/AIK21/log/db_target.log shows:


    while df -m /dev/shm shows:

    aleph@library(a21_1) XXX01> df -m /dev/shm
    Filesystem 1M-blocks Used Available Use% Mounted on
    tmpfs 1975 1296 680 66% /dev/shm

    680m is less than 1536m, so /dev/shm is less than memory_target. This means that, while this database wants to have 1,536M shm (shared memory), this server "library" has only 680M available.
