Database size

The size of the database is the space the files physically consume on disk. You can find this with: 

select sum(bytes)/1024/1024 size_in_mb from dba_data_files;

But not all this space is necessarily allocated. There could be sections of these files that are not used. 

You can find the total space that is used with: 

select sum(bytes)/1024/1024 size_in_mb from dba_segments;

You can break this down by user by running: 

select owner, sum(bytes)/1024/1024 Size_MB from dba_segments
group  by owner;

Check used and free space:

select

"Reserved_Space(GB)", "Reserved_Space(GB)" - "Free_Space(GB)" "Used_Space(MB)","Free_Space(GB)"

from(

select

(select sum(bytes/(1014*1024*1024)) from dba_data_files) "Reserved_Space(GB)",

(select sum(bytes/(1024*1024*1024)) from dba_free_space) "Free_Space(GB)"

from dual

);

Configuring Clients for Environments with Both Shared and Dedicated Servers

If a shared server is configured on the server side, and a client connection request arrives when no dispatchers are registered, then the request is processed by a dedicated server process. If you want a particular client always to use a dispatcher, then configure (SERVER=shared) in the CONNECT_DATA section of the connect descriptor. For example:

sales=
(DESCRIPTION=
  (ADDRESS=(PROTOCOL=tcp)(HOST=sales-server)(PORT=1521))
  (CONNECT_DATA=
     (SERVICE_NAME=sales.us.example.com)
     (SERVER=shared)))

If the (SERVER=shared) attribute is configured and a dispatcher is not available, then the client connection request is rejected, and a message is sent to the client.

If the database is configured for a shared server and a particular client requires a dedicated server, then you can configure the client to use a dedicated server in one of the following ways:

• You can configure a network service name with a connect descriptor that contains (SERVER=dedicated) in the CONNECT_DATA section. For example:
  sales=
  (DESCRIPTION=
    (ADDRESS=(PROTOCOL=tcp)(HOST=sales-server)(PORT=1521))
    (CONNECT_DATA=
       (SERVICE_NAME=sales.us.example.com)
       (SERVER=dedicated)))
• You can configure the client profile file, sqlnet.ora, with USE_DEDICATED_SERVER=on. This adds (SERVER=dedicated) to the CONNECT_DATA section of the connect descriptor the client uses.
  Note:
  If USE_DEDICATED_SERVER is set to ON, then existing (SERVER=value) entries in connect descriptors are overwritten with (SERVER=dedicated).
