5 Workspace Manager Static Data Dictionary Views

Workspace Manager creates and maintains static data dictionary views to hold information about such things as version-enabled tables, workspaces, savepoints, users, privileges, locks, and conflicts.

These views are read-only to users. You can use the information in these views to help administer the Workspace Manager environment and diagnose problems.

There are also views created for each version-enabled table, as follows:

  • Conflict view, each having a name in the form <table_name>_CONF. (See xxx_CONF Views.)

  • Difference view, each having a name in the form <table_name>_DIFF. (See xxx_DIFF Views.)

  • History view (if history tracking is enabled), each having a name in the form <table_name>_HIST. (See xxx_HIST Views.)

  • Lock view, each having a name in the form <table_name>_LOCK. (See xxx_LOCK Views.)

  • Multiworkspace view, each having a name in the form <table_name>_MW. (See xxx_MW Views.)

Note:

When an ALL_xxx or USER_xxx view is queried from a procedure, the results returned are based on whether the procedure has definer's rights or the rights of the database user whose privileges are currently active.

CDB_xxx Views

For every DBA_xxx view, a CDB_xxx view is defined. In the root of a multitenant container database (CDB), CDB_xxx views can be used to obtain information about tables, tablespaces, users, privileges, parameters, and so on contained in the root and in pluggable databases (PDBs).

CDB_xxx views are container data objects. When a user connected to the root queries a CDB_xxx view, the query results will depend on the CONTAINER_DATA attribute for users for the view. The CONTAINER_DATA clause of the SQL ALTER USER statement is used to set and modify users' CONTAINER_DATA attribute.

The CDB_xxx views are owned by SYS, regardless of which user owns the underlying DBA_xxx view.

By default, a user connected to the root will only see data pertaining to the root.

In a PDB, the CDB_xxx views only show objects visible through a corresponding DBA_xxx view.

In addition to all the columns found in a given DBA_xxx view, the corresponding CDB_xxx view also contains the CON_ID column, which identifies a container whose data a given CDB_* row represents. In a non-CDB, the value of a CON_ID column will be 0.

CDB views can return data from different containers in a CDB when queried from the root container. These objects will implicitly convert data to the character set of the root container (AL32UTF8) and then return the result to the user. Some character sets may have character expansion (more bytes needed to represent a character) when converted to AL32UTF8, so there may be data truncation if the view column width is not able to accommodate data from a given PDB.

Data returned by these views depends on whether a given PDB is open at the time the query is issued. In particular, in an Oracle RAC environment, data returned by these view may vary according to the instance to which a session is connected.

5.51 xxx_CONF Views

There is one conflict view for each version-enabled table. Each conflict view has a name in the form <table_name>_CONF. For example, if the EMPLOYEE table is version-enabled, the EMPLOYEE_CONF metadata view exists.

Each conflict view contains the columns shown in Table 5-1.

Table 5-1 Columns in the xxx_CONF Views

Column Datatype Description

WM_WORKSPACE

VARCHAR2(256)

Workspace in which the conflict exists.

(One column for each column in original table)

(Same as column in original table)

Value of the column in this workspace.

WM_VALID

WM_PERIOD

Time period during which the row is valid, if the table has valid time support (described in Workspace Manager Valid Time Support).

If you set the USE_SCALAR_TYPES_FOR_VALIDTIME system parameter (described in System Parameters for Workspace Manager) to ON, this column is replaced by two columns, WM_VALIDFROM and WM_VALIDTILL, of type TIMEZONE WITH TIMESTAMP.

WM_DELETED

VARCHAR2(3)

YES if the row has been deleted; NO if the row has not been deleted; NE if the row is nonexistent (does not exist).

WM_CONFLICTPERIOD

WM_PERIOD

Overlapping period of the rows for which conflicts were detected, if the table has valid time support (described in Workspace Manager Valid Time Support).

A SELECT operation from a conflict view uses the workspace conflict context established by the GotoWorkspace procedure, unless you have specified a workspace conflict context for the session by using the SetConflictWorkspace procedure. Selecting from the conflict view finds rows in that table that are changed in the current workspace context, and compares their values with corresponding rows in the parent workspace to identify conflicts. If the current workspace conflict context is the LIVE workspace, all rows in the table are selected and no conflicts are found.

The following example lists the key value and all column values of conflicting rows in the EMPLOYEE table in the current workspace and its parent workspace. The conflict view reflects the context established by a previous call to the GetWorkspace or SetConflictWorkspace procedure to set the workspace conflict context (the current workspace in this case). 

SELECT * FROM EMPLOYEE_CONF;

If ID, NAME, and CITY are the columns in the EMPLOYEE table, then assume the following values: 

WM_WORKSPACE  ID   NAME    CITY     WM_DELETED
NEWWORKSPACE  12   SMITH   NASHUA   NO
DiffBase      12   SMITH   NY       NO
LIVE          12   SMITH   BOSTON   NO

The database row identified by ID = 12 was changed in NEWWORKSPACE and LIVE workspaces. In NEWWORKSPACE the city was changed to NASHUA, and in the LIVE workspace the city was changed to BOSTON. When NEWWORKSPACE is merged into LIVE, this row will show up as a conflict. The application must pick between the choices and resolve conflicts in favor of the workspace with the desired value.

Note that DiffBase refers to the common ancestor (or base), as explained in the Usage Notes for the SetDiffVersions procedure.

The following example begins a conflict resolution session, calls the ResolveConflicts procedure to delete the conflicting row from the NEWWORKSPACE workspace and to insert the value in the parent workspace (LIVE) into both workspaces, commits the transaction, and ends the conflict resolution session. 

DBMS_WM.BeginResolve ('NEWWORKSPACE');
DBMS_WM.ResolveConflicts ('NEWWORKSPACE', 'EMPLOYEE', 'ID = 12', 'PARENT');
COMMIT;
DBMS_WM.CommitResolve ('NEWWORKSPACE');

For additional information about conflict resolution, see Resolving Conflicts Before a Merge or Refresh Operation.

5.52 xxx_DIFF Views

There is one difference view for each version-enabled table. Each difference view has a name in the form <table_name>_DIFF. For example, if the EMPLOYEE table is version-enabled, the EMPLOYEE_DIFF metadata view exists. Rows are added to one or more xxx_DIFF views each time the SetDiffVersions procedure is executed.

Each difference view contains the columns shown in Table 5-2.

Table 5-2 Columns in the xxx_DIFF Views

Column Datatype Description

(One column for each column in original table)

(Same as column in original table)

Value of the column in this workspace.

WM_VALID

WM_PERIOD

Time period during which the row is valid, if the table has valid time support (described in Workspace Manager Valid Time Support).

If you set the USE_SCALAR_TYPES_FOR_VALIDTIME system parameter (described in System Parameters for Workspace Manager) to ON, this column is replaced by two columns, WM_VALIDFROM and WM_VALIDTILL, of type TIMEZONE WITH TIMESTAMP.

WM_DIFFVER

VARCHAR2(256)

Branch from which the values in the preceding columns are taken. (See the explanation following this table.)

WM_CODE

VARCHAR2(2)

One of the following codes describing the change: U (updated), D (deleted), I (inserted), NC (no change), NE (nonexistent).

WM_DIFFPERIOD

WM_PERIOD

Overlapping period of the rows for which a difference was detected, if the table has valid time support (described in Workspace Manager Valid Time Support).

The WM_DIFFVER value is in one of the following formats:

  • '<workspace1>, <savepoint1>'

  • '<workspace2>, <savepoint2>'

  • 'DiffBase'

If the two-parameter version of the SetDiffVersions procedure was used, the value of savepoint1 or savepoint2 is LATEST.

Note the following about the possible values for WM_CODE:

  • NC will appear for rows in workspaces that did not change the value when another workspace did change the value. For example, if '<workspace2>, <savepoint2>' updated the row, the code for that row is U, but the code for the '<workspace1>, <savepoint1>' and 'DiffBase' rows is NC if they did not modify the row.

  • NE will appear for 'DiffBase' if a row is inserted in one or more branches, and NE will appear for 'DiffBase' and a branch if only one branch has had any insert operations.

For more information, including an example showing rows being added to a differences view, see the section on the SetDiffVersions procedure in DBMS_WM Package: Reference .
