DICTIONARY_SCHEMA

DICTIONARY_SCHEMA contains views or tables to get SQL objects and their information in the system.

The views and tables in DICTIONARY_SCHEMA can be retrieved from the open phase.

Execute DictionarySchema.sql as follows to use the views.

For standalone

% gsql sys gliese --as sysdba --import $GOLDILOCKS_HOME/admin/standalone/DictionarySchema.sql

For cluster

% gsql sys gliese --as sysdba --import $GOLDILOCKS_HOME/admin/cluster/DictionarySchema.sql

Information is retrieved as follows according to the names of views or tables.

ALL-family view
- The view name begins with ALL_
- Information about accessible objects by a current user
DBA-family view
- The view name begins with DBA_
- Information about all objects whose current user has DBA privileges (ACCESS CONTROL ON DATABASE).
USER-family view
- The view name begins with USER_
- Information about objects which are owned by the current user

GV$ Global View

The cluster provides GV$ view corresponding to almost every V$ views.
V$ view retrieves the information of the currently connected server, but GV$ view retrieves the information of all servers. 
GV$ view includes all column information of V$ view, and it additionally has ORIGIN_MEMBER_NAME column which is a server having acquired the data (cluster member).

It is available only on a cluster.

For example, V$TRANSACTION information retrieves the transaction information of the currently connected server as follows.

gSQL> SELECT TRANS_ID, SESSION_ID, TRANS_VIEW_SCN, START_TIME FROM V$TRANSACTION;

TRANS_ID SESSION_ID TRANS_VIEW_SCN START_TIME                
-------- ---------- -------------- --------------------------
40501296         48 1098.1.26      2017-04-07 17:14:01.912637

On the other hand, GV$TRANSACTION information retrieves the transaction information of all servers as follows.

gSQL> SELECT ORIGIN_MEMBER_NAME, TRANS_ID, SESSION_ID, TRANS_VIEW_SCN, START_TIME FROM GV$TRANSACTION;

ORIGIN_MEMBER_NAME TRANS_ID SESSION_ID TRANS_VIEW_SCN START_TIME                
------------------ -------- ---------- -------------- --------------------------

In the example above, the ORIGIN_MEMBER_NAME information indicates that the transaction information were obtained from the cluster members corresponding to G1N1, G2N1, G1N2, G2N2 each.

The information of a specific remote server can be retrieved by using the condition for ORIGIN_MEMBER_NAME column as follows.

gSQL> 
SELECT ORIGIN_MEMBER_NAME, TRANS_ID, SESSION_ID, TRANS_VIEW_SCN, START_TIME 
  FROM GV$TRANSACTION 
WHERE ORIGIN_MEMBER_NAME IN ( 'G2N1', 'G3N2' );

ORIGIN_MEMBER_NAME TRANS_ID SESSION_ID TRANS_VIEW_SCN START_TIME
