General Information

Library Note

Morgan's Library Page Header

The Library is currently in the process of being upgraded from Oracle Database Version 12.1.0.2 to 12.2.0.1. Demos are being upgraded to reflect the new Container paradigm as well as EBR (Edition Based Redefinition) and may contain references to CDBs, PDBs, and other objects you may not be familiar with such as CDB_OBJECTS_AE: Welcome to 12c.

Also important ... there are rumors on the web about SPARC and Solaris being discontinued. Welcome to the age of fake news. There is absolutely not a byte of truth to these irresponsible rumors.

Purpose File system operations definition.

Subprograms

Creates a file system of type specified by file system type and name similar to mkfs on Unix dbms_fs.make_oracle_fs( fstype IN VARCHAR2, fsname IN VARCHAR2, fsoptions IN VARCHAR2); -- comma separated file system create options

exec dbms_fs.make_oracle_fs('FUBAR', 'FUBAR', 'FUBAR');

The fact that this runs successfully, and there are no dependencies, unfortunately tells us nothing about it.

MOUNT_ORACLE_FS

Mount an Oracle file system on the specified mount point similar to mount in Unix dbms_fs.mount_oracle_fs ( fstype IN VARCHAR2, fsname IN VARCHAR2, mount_point IN VARCHAR2, mount_options IN VARCHAR2);

exec dbms_fs.mount_oracle_fs('FUBAR', 'FUBAR', '/fubar', 'FUBAR');

-- Doing this hang the session and the system ... SYSDBA can log on but a SHUTDOWN IMMEDIATE does not work forcing an ABORT.

UNMOUNT_ORACLE_FS

Unmount an Oracle file system on the specified mount point similar to umount in Unix dbms_fs.unmount_oracle_fs( fsname IN VARCHAR2, mount_point IN VARCHAR2);

exec dbms_fs.unmount_oracle_fs('FUBAR',  '/fubar');

      

      -- Doing this hang the session and the system ... SYSDBA can log on but a SHUTDOWN IMMEDIATE does not work forcing an ABORT.
