Workspace Manager creates and maintains metadata 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 Section 5.42.)
Difference view, each having a name in the form <table_name>_DIFF. (See Section 5.43.)
History view (if history tracking is enabled), each having a name in the form <table_name>_HIST. (See Section 5.44.)
Lock view, each having a name in the form <table_name>_LOCK. (See Section 5.45.)
Multiworkspace view, each having a name in the form <table_name>_MW. (See Section 5.46.)

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 |
|---|---|---|
|
|
|
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. |
|
|
|
Time period during which the row is valid, if the table has valid time support (described in Chapter 3). |
|
|
|
|
|
|
|
Overlapping period of the rows for which conflicts were detected, if the table has valid time support (described in Chapter 3). |
The following example lists the key value and all column values of conflicting rows in the EMPLOYEE table in the current workspace and the parent workspace. This view is available after the SetConflictWorkspace procedure has been called specifying the child workspace (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_DEL 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.
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 Section 1.1.4.
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. |
|
|
|
Time period during which the row is valid, if the table has valid time support (described in Chapter 3). |
|
|
|
Branch from which the values in the preceding columns are taken. (See the explanation following this table.) |
|
|
|
One of the following codes describing the change: |
|
|
|
Overlapping period of the rows for which a difference was detected, if the table has valid time support (described in Chapter 3). |
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 Chapter 4.
There is one history view for each version-enabled table if the table was version-enabled with the hist parameter set to VIEW_W_OVERWRITE or VIEW_WO_OVERWRITE in the call to the EnableVersioning procedure. Each history view has a name in the form <table_name>_HIST. For example, if the EMPLOYEE table is version-enabled with the hist parameter set to VIEW_W_OVERWRITE or VIEW_WO_OVERWRITE, the EMPLOYEE_HIST metadata view exists.
You can use the history views to log and audit modifications to version-enabled tables.
Each history view contains the columns shown in Table 5-3.
Table 5-3 Columns in the xxx_HIST 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. |
|
|
|
Time period during which the row is valid, if the table has valid time support (described in Chapter 3). |
|
|
|
Name of the workspace containing the row. |
|
|
|
Version number of the row with which the data is associated. |
|
|
|
Name of the user that created the row. |
|
|
|
Type of change operation that was performed on the row: |
|
|
|
Time when the row was created or updated. |
|
|
|
Time when the row was deleted or modified. |
There is one lock view for each version-enabled table. Each lock view has a name in the form <table_name>_LOCK. For example, if the EMPLOYEE table is version-enabled, the EMPLOYEE_LOCK metadata view exists. (For an explanation of Workspace Manager locking, see Section 1.3.)
Each lock view contains the columns shown in Table 5-4.
Table 5-4 Columns in the xxx_LOCK Views
| Column | Datatype | Description |
|---|---|---|
|
(One column for each column in original table) |
(Same as column in original table) |

|
|
|
Type of lock: |
|
|
|
User name of the owner of the lock. |
|
|
|
Name of the workspace in which the lock was placed. |
|
|
|
|
There is one multiworkspace view for each version-enabled table. Each multiworkspace view has a name in the form <table_name>_MW. For example, if the EMPLOYEE table is version-enabled, the EMPLOYEE_MW metadata view exists. Rows are added to one or more xxx_MW views each time the SetMultiWorkspaces procedure (described in Chapter 4) is executed.
Each multiworkspace view contains the columns shown in Table 5-5.
Table 5-5 Columns in the xxx_MW 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. |
|
|
|
Time period during which the row is valid, if the table has valid time support (described in Chapter 3). |
|
|
|
Workspace containing the row that was modified. |
|
|
|
Comma-delimited list of workspaces from which the row is visible. |
|
|
|
One of the following codes describing the change: |
You can use the <table_name>_MW view to see changes in another workspace without leaving the current workspace (for example, to check if there is a conflict with the other workspace). Each row in the view shows the data as it would be in that workspace if the workspace had been merged when the row was inserted in the view.
You can also use the <table_name>_DIFF view (see Section 5.43) to see changes in another workspace without leaving the current workspace; however, the <table_name>_DIFF view can be used for only two workspaces, whereas the <table_name>_MW view can be used for any number of workspaces. In addition, the <table_name>_DIFF view shows deleted rows, whereas the <table_name>_MW view does not show deleted rows.
For more information and several examples, see the information about the SetMultiWorkspaces procedure in Chapter 4.
