When configuring database creation for Oracle DB 21c-1.0 XE, I get errors about values.

The configure program is complaining about the SHARED_POOL_SIZE being too small (2560MB, wants it to be at least 3600). Also, about sga_target being too small. Where can I set these values so that the DB creation will succeed?

    The PFILE used to start the database instance for the very first time. Default is (used to be) in directory $ORACLE_HOME/dbs.

    Hi @User_7BQNJ ,

    With 21c, you can also use memory_target and sga_target instead of setting shared_pool_size individually.

    I tried setting sga_target in the dbs/init.ora file which got rid of that specific message, but still get shared_pool_size error messages. I am pasting the output from the configure run, and also the contents of init.ora for review. Thanks.
