MAKE Procedure

This procedure specifies the members of a refresh group and the time interval used to determine when the members of this group should be refreshed.

Table 17-5 MAKE Procedure Parameters  
Parameter Description

Unique name used to identify the refresh group. Refresh groups must follow the same naming conventions as tables.


Comma-delimited list of materialized views that you want to refresh. (Synonyms are not supported.) These materialized views can be located in different schemas and have different master tables or master materialized views. However, all of the listed materialized views must be in your current database.


Instead of a comma separated list, you can supply a PL/SQL index-by table of names of materialized views that you want to refresh using the datatype DBMS_UTILITY.UNCL_ARRAY. If the table contains the names of n materialized views, then the first materialized view should be in position 1 and the n + 1 position should be set to NULL.


Next date that you want a refresh to occur.


Function used to calculate the next time to refresh the materialized views in the group. This field is used with the next_date value.

For example, if you specify NEXT_DAY(SYSDATE+1, "MONDAY") as your interval, and if your next_date evaluates to Monday, then Oracle refreshes the materialized views every Monday. This interval is evaluated immediately before the refresh. Thus, you should select an interval that is greater than the time it takes to perform a refresh.


Set this to true if you want to delete the refresh group automatically when it no longer contains any members. Oracle checks this flag only when you call the SUBTRACT procedure. That is, setting this flag still enables you to create an empty refresh group.


A materialized view can belong to only one refresh group at a time. If you are moving a materialized view from an existing group to a new refresh group, then you must set this to true to succeed. Oracle then automatically removes the materialized view from the other refresh group and updates its refresh interval to be that of its new group. Otherwise, the call to MAKE generates an error message.


Needed by the Import utility. Use the default value, 0.


Name of the rollback segment to use while refreshing materialized views. The default, NULL, uses the default rollback segment.


Used by updatable materialized views only. Use the default value, true, if you want to push changes from the materialized view to its associated master table or master materialized view before refreshing the materialized view. Otherwise, these changes may appear to be temporarily lost.


Used by updatable materialized views only. Set this to 0 if you want the refresh to proceed even if there are outstanding conflicts logged in the DEFERROR view for the materialized view's master table or master materialized view.


If you are using the parallel propagation mechanism (in other words, parallelism is set to 1 or greater), then 0 = do not purge; 1 = lazy (default); 2 = aggressive. In most cases, lazy purge is the optimal setting.

Set purge to aggressive to trim back the queue if multiple master replication groups are pushed to different target sites, and updates to one or more replication groups are infrequent and infrequently pushed. If all replication groups are infrequently updated and pushed, then set purge to do not purge and occasionally execute PUSH with purge set to aggressive to reduce the queue.


0 specifies serial propagation.

n > 1 specifies parallel propagation with n parallel processes.

1 specifies parallel propagation using only one parallel process.


Maximum number of transactions to be examined simultaneously for parallel propagation scheduling. Oracle automatically calculates the default setting for optimal performance.

Note: Do not set this parameter unless directed to do so by Oracle Support Services.
