P or p refreshes by recomputing the rows in the materialized view affected by changed partitions in the detail tables. Arbitrary string used to identify the statement in an EXPLAIN PLAN. Table 100-10 REFRESH Procedure Parameters. Scripting on this page enhances content navigation, but does not change the content in any way. Table 100-9 PURGE_MVIEW_FROM_LOG Procedure Parameters. Use this parameter to direct EXPLAIN_MVIEW's output to a PL/SQL VARRAY rather than MV_CAPABILITIES_TABLE. Applies to: Oracle Warehouse Builder - Version 11.2.0.1 and later Information in this document applies to any platform. This procedure refreshes all materialized views that have the following properties: The materialized view has not been refreshed since the most recent change to a master table or master materialized view on which it depends. Alternatively, you may pass in a PL/SQL index-by table of type DBMS_UTILITY.UNCL_ARRAY, where each element is the name of a materialized view. Table 100-14 UNREGISTER_MVIEW Procedure Parameters. Nested refresh operations refresh all the depending materialized views of the specified set of tables based on a dependency order to ensure the nested materialized views are truly fresh with respect to the underlying base tables. This script creates a table named REWRITE_TABLE in the current schema. In most cases, lazy purge is the optimal setting. To obtain the output into a table, you must run the utlxrw.sql script before calling EXPLAIN_REWRITE. However, all of the listed materialized views must be in your local database. Query the DBA_REGISTERED_MVIEWS view at the materialized view log site to view the materialized view owners. Nested refresh operations refresh all the depending materialized views of the specified set of tables based on a dependency order to ensure the nested materialized views are truly fresh with respect to the underlying base tables. In this case, use the plus sign (+) to specify more than one property. This procedure enables the administration of individual materialized views. Alternatively, you may pass in a PL/SQL index-by table of type DBMS_UTILITY.UNCL_ARRAY, where each element is the name of a table. SQL> exec dbms_mview.refresh('MY_MV',atomic_refresh=>TRUE); If you do not specify an atomic refresh (by setting "atomic refresh = FALSE" in dbms_mview.refresh_all_mviews) then you can optimize the materialized view refresh with these mechanisms: - Parallel DML - Truncate DDL It is invoked at a master site or master materialized view site to register a materialized view. If you want to direct the output of EXPLAIN_REWRITE to a VARRAY instead of a table, you should call the procedure as follows: Note that if the query is less than 256 characters long, EXPLAIN_REWRITE can be easily invoked with the EXECUTE command from SQL*Plus. This name should not contain any double quotes. Harel Safra Xu, Roger wrote: There are dbms_refresh.add, dbms_refresh.subtract, etc. This package allow the user to refresh snapshots and purge logs providing API supporting the refreshing of snapshot (materialized view) that are not part of the same refresh group and purging of MV snapshot logs. This procedure is invoked at the master site or master materialized view site by a remote materialized view site using a remote procedure call. For example, you can determine if a materialized view is fast refreshable and what types of query rewrite you can perform with a particular materialized view. (Synonyms are not supported.) Otherwise, an insufficient privileges error will be thrown. You must run the utlxmv.sql script to create MV_CAPABILITIES_TABLE in the current schema prior to calling EXPLAIN_MVIEW except when you direct output to a VARRAY. SQL> SQL> (and explicit fast refresh worked as well) SQL> exec DBMS_MVIEW.REFRESH('"MCDONAC". F or f indicates fast refresh, ? This procedure purges rows from the materialized view log. The rowid of a row entry in a master table. In most cases, lazy purge is the optimal setting. Note: Do not set this parameter unless directed to do so by Oracle Support Services. If this parameter is set to false, then each of the materialized views is refreshed in a separate transaction. All of the refreshed materialized views are updated to a single point in time. If true, then it performs an out-of-place refresh. For example, the following statement deletes rows needed to refresh the two least recently refreshed materialized views: To delete all rows in the materialized view log, indicate a high number of materialized views to disregard, as in this example: DBMS_MVIEW.PURGE_LOG('master_table',9999); This statement completely purges the materialized view log that corresponds to master_table if fewer than 9999 materialized views are based on master_table. These tables and the materialized views that depend on them can be located in different schemas. A return value of true indicates that all local replication triggers for materialized views are effectively disabled in this session because each replication trigger first checks this state. For example, the following EXECUTE statement within SQL*Plus: performs a complete refresh of the materialized views that depend on the employees table, a fast refresh of the materialized views that depend on the departments table, and a default refresh of the materialized views that depend on the hr.regions table. P or p refreshes by recomputing the rows in the materialized view affected by changed partitions in the detail tables. FUNCTION get_security_predicate(obj_schema VARCHAR2, obj_name VARCHAR2) RETURN VARCHAR2 is d_predicate VARCHAR2(2000); is_refresh boolean := true; cursor c1 is select s_rls_filter.COLUMN_NAME || ' ' || s_rls_filter.OPERATOR || ' ' || s_rls_filter.VALUE || s_rls_filter.wherecls pred from s_group_function,s_function,s_session, s_group_user,s_rls_filter where … This procedure enables you to learn why a query failed to rewrite, or, if it rewrites, which materialized views will be used. If the refresh fails for any of the materialized views, none of the materialized views are updated. There are two ways to get the output from DBMS_MVIEW.EXPLAIN_MVIEW, via a table or via a varray. For example, if a primary key materialized view can be fast refreshed, you can enter the following for this parameter: DBMS_MVIEW.REG_PRIMARY_KEY_MVIEW + DBMS_MVIEW.REG_FAST_REFRESHABLE_MVIEW. If a query is less than 256 characters long, you can invoke EXPLAIN_REWRITE using the EXECUTE command from SQL*Plus. You must run the utlxmv.sql script to create MV_CAPABILITIES_TABLE in the current schema prior to calling EXPLAIN_MVIEW except when you direct output to a VARRAY. As part of complete refresh, if truncate is used (non-atomic refresh), unique index rebuild is executed. DBMS_SNAPSHOT is a synonym for DBMS_MVIEW. Syntax DBMS_MVIEW.I_AM_A_REFRESH RETURN BOOLEAN; Return Values. It must be called before a master table is reorganized. In contrary of views, materialized views avoid executing the SQL query for every access by storing the result set of the query. The materialized view depends on a master table or master materialized view in the list of specified masters. If all the required privileges are met, the subprogram will be executed. --Refresh group is a Group of Mviews. However, all of the tables and materialized views must be in your local database. A materialized view can have more than one of these properties. If you do not specify a mview_id, enter the site of the target materialized view using the mviewsite parameter. A string of refresh methods indicating how to refresh the dependent materialized views. This chapter contains the following topics: If a query is less than 256 characters long, you can invoke EXPLAIN_REWRITE using the EXECUTE command from SQL*PLUS. * DBMS_MVIEW.REFRESH_DEPENDENT—Refreshes all table-based materialized views Manual complete refresh A complete refresh occurs when the materialized view is initially defined, unless it references a prebuilt table, and a complete refresh may be requested at … The following shows the basic syntax for using an output table: You can create an output table called REWRITE_TABLE by executing the utlxrw.sql script. Use this parameter to direct EXPLAIN_MVIEW's output to a PL/SQL VARRAY rather than MV_CAPABILITIES_TABLE. It also enables you to refresh materialized views that are not part of the same refresh group and purge logs. Otherwise, these changes may appear to be temporarily lost. This procedure ensures that the materialized view data for the master table is valid and that the master table is in the proper state. The PL/SQL varray that receives the output. When it is not specified, EXPLAIN_REWRITE returns any relevant messages regarding all the materialized views considered for rewriting the given query. This chapter contains the following topics: This section contains topics which relate to using the DBMS_MVIEW package. Specify an Oracle database version 8.x and higher materialized view as a BINARY_INTEGER. These restrictions also apply when passing the defining query of a materialized view to the EXPLAIN_MVIEW procedure. It must be called after a master table is reorganized. Each package subprogram is executed by first checking the privileges against the invoker. A simple wrapper of create or replace Procedure DIM_REFRESH_MV (MV_NAME IN VARCHAR2, REFRESH_METHOD IN VARCHAR2) If you are using the parallel propagation mechanism (in other words, parallelism is set to 1 or greater), 0 means do not purge, 1 means lazy purge, and 2 means aggressive purge. The privilege model is generally based on the invoker's right. This parameter can override the setting for the parameter num. MVIEWs are sorted and refreshed in alphabetical order from 10g onwards. Valid constants that can be assigned include the following: DBMS_MVIEW.REG_V7_SNAPSHOT if the materialized view is at an Oracle database version 7 site, reg_repapi_snapshot if the materialized view is at an Oracle database version 8.x or higher site, DBMS_MVIEW.REG_UNKNOWN (the default) if you do not know whether the materialized view is at an Oracle database version 7 site or an Oracle database version 8.x (or higher) site. Name of the materialized view site for a materialized view registering at an Oracle database version 8.x and higher master site or master materialized view site. The script is found in the ADMIN directory. If you do not specify a mview_id, enter the name of the target materialized view using the mviewname parameter. Maximum number of transactions to be examined simultaneously for parallel propagation scheduling. For example, the following statement deletes rows needed to refresh the two least recently refreshed materialized views: To delete all rows in the materialized view log, indicate a high number of materialized views to disregard, as in this example: DBMS_MVIEW.PURGE_LOG('master_table',9999); This statement completely purges the materialized view log that corresponds to master_table if fewer than 9999 materialized views are based on master_table. If you are using the parallel propagation mechanism (in other words, parallelism is set to 1 or greater), 0 means do not purge, 1 means lazy purge, and 2 means aggressive purge. You can also use EXPLAIN_REWRITE with multiple materialized views, in which case the syntax will be the same as with a single materialized view, except that the materialized views are specified by a comma-delimited string. This procedure removes entries from the direct loader log after they are no longer needed for any known materialized view. Number of least recently refreshed materialized views whose rows you want to remove from materialized view log. Oracle | Toad expert blog for developers, admins and data analysts. this group can contain 1 or More Mviews and all the Mvies in one refresh group can be refershed using 'DBMS_REFRESH.REFRESH ('apps.TEST_TABLE_JK_MV'); ' -- we can Query the Referesh group details using below select statement it will return the record with the regersh group name 'TEST_TABLE_JK' This procedure enables you to learn why a query failed to rewrite, or, if it rewrites, which materialized views will be used. This function returns the value of the I_AM_REFRESH package state. A materialized view can have more than one of these properties. Alternatively, you can specify the SELECT string or CREATE MATERIALIZED VIEW statement for a potential materialized view. Instead, I create a procedure to refresh the materialized view using dbms_mview.refresh. The identification number of the materialized view. (Synonyms are not supported.) You can obtain the output from EXPLAIN_REWRITE in two ways. Name of the materialized view site rollback segment to use while refreshing materialized views. 1 specifies parallel propagation using only one parallel process. When schema is omitted and only mv is specified, EXPLAIN_REWRITE looks for the materialized view in the current schema. Alternatively, you may pass in a PL/SQL index-by table of type DBMS_UTILITY.UNCL_ARRAY, where each element is the name of a table. Table 100-4 ESTIMATE_MVIEW_SIZE Procedure Parameters, Arbitrary string used to identify the statement in an EXPLAIN PLAN. If true, then perform nested refresh operations for the specified set of materialized views. If a table does not have a corresponding refresh method (that is, if more tables are specified than refresh methods), then any materialized view that depends on that table is refreshed according to its default refresh method. A return value of true indicates that all local replication triggers for materialized views are effectively disabled in this session because each replication trigger first checks this state. All of the refreshed materialized views are updated to a single point in time. If you do not specify an mview_id, enter the owner of the target materialized view using the mviewowner parameter. Specify an Oracle database version 7 materialized view registering at an Oracle database version 8.x and higher master sites or master materialized view sites as a DATE. This procedure does not unregister the materialized view. The first 32,000 bytes of the materialized view definition query. Nested refresh operations refresh all the depending materialized views and the specified set of materialized views based on a dependency order to ensure the nested materialized views are truly fresh with respect to the underlying base tables. Comma-delimited list of materialized views that you want to refresh. The materialized view is in the view DBA_MVIEWS. Otherwise, the recommended method is to use a PL/SQL BEGIN..END block, as shown in the examples in /rdbms/demo/smxrw.sql. This procedure usually is used in environments using Oracle's data warehousing technology. DBMS_MVIEW.REFRESH(mview_name, method =>’P’) Materialized View Execution Plans The explain plan feature shows you whether a materialized view is being accessed as a result of a query rewrite or because you specified direct materialized view access. indicates force refresh, C or c indicates complete refresh, and A or a indicates always refresh. This procedure performs a process to preserve materialized view data needed for refresh. I need to understand what this code is doing execute DBMS_MVIEW.REFRESH('briir. A and C are equivalent. Query the DBA_REGISTERED_MVIEWS view at the materialized view log site to view the materialized view names. You simply call DBMS_MVIEW.EXPLAIN_MVIEW, passing in as parameters the schema and materialized view name for an existing materialized view. It also enables you to refresh materialized views that are not part of the same refresh group and purge logs. If you want to execute this procedure based on the identification of the target materialized view, specify the materialized view identification using the mview_id parameter. $ORACLE_HOME/rdbms/admin/utlxmv.sql. The PL/SQL varray that receives the output. When "atomic refresh" is set to TRUE (in dbms_mview.refresh_all_mviews), than the whole refresh is done in a single transaction. A client-supplied unique identifier to distinguish output messages. A client-supplied unique identifier to associate output rows with specific invocations of EXPLAIN_MVIEW. You simply call DBMS_MVIEW.EXPLAIN_MVIEW, passing in as parameters the schema and materialized view name for an existing materialized view. If a materialized view does not have a corresponding refresh method (that is, if more materialized views are specified than refresh methods), then that materialized view is refreshed according to its default refresh method. Table 100-13 REGISTER_MVIEW Procedure Parameters. Comma-delimited list of master tables or master materialized views on which materialized views can depend. A string of refresh methods indicating how to refresh the listed materialized views. For example, if a primary key materialized view can be fast refreshed, you can enter the following for this parameter: DBMS_MVIEW.REG_PRIMARY_KEY_MVIEW + DBMS_MVIEW.REG_FAST_REFRESHABLE_MVIEW. P or p refreshes by recomputing the rows in the materialized view affected by changed partitions in the detail tables. Oracle automatically calculates the default setting for optimal performance. P or p refreshes by recomputing the rows in the materialized view affected by changed partitions in the detail tables. exec dbms_mview.refresh('mviewname','c','atomic_refresh=>FALSE) is giving error Oracle 10gR2 F or f indicates fast refresh, ? Refresh the Materialized View. Table 100-5 EXPLAIN_MVIEW Procedure Parameters. This procedure does not unregister the materialized view. In this case, use the plus sign (+) to specify more than one property. For example, the following statement deletes rows from the materialized view log that has dependency rows in the least recently refreshed materialized view: DBMS_MVIEW.PURGE_LOG('master_table',1,'delete'); This procedure is called on the master site or master materialized view site to delete the rows in materialized view refresh related data dictionary tables maintained at the master for the specified materialized view identified by mview_id or the combination of mviewowner, mviewname, and mviewsite. If this parameter is set to false, then each of the materialized views is refreshed non-atomically in separate transactions. If this parameter is true and atomic_refresh is false, this procedure continues to refresh other materialized views if it fails while refreshing a materialized view. This procedure refreshes a list of materialized views. The query specified in the EXPLAIN_REWRITE statement is never actually executed. If this parameter is true and atomic_refresh is false, this procedure continues to refresh other materialized views if it fails while refreshing a materialized view. You can determine the properties of a materialized view by querying the ALL_MVIEWS data dictionary view. The materialized view or potential materialized view is then analyzed and the results are written into either a table called MV_CAPABILITIES_TABLE, which is the default, or to an array called MSG_ARRAY. If there is an error while purging one of the materialized view logs, the successful purge operations of the previous materialized view logs are not rolled back. These tables and the materialized views that depend on them can be located in different schemas. The EXPLAIN_REWRITE procedure cannot accept queries longer than 32627 characters. _____ From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of Stefan Knecht Sent: Sunday, April 30, 2006 11:00 PM To: oracle-l@xxxxxxxxxxxxx Subject: Re: Refresh materialized view by other user then owner From what I can see from your posting: begin DBMS_MVIEW.REFRESH('sys.My_View','c'); end; You're creating the materialized view in schema … We have to manually add the materialized view back to the refresh group. These materialized views can be located in different schemas and have different master tables or master materialized views. If this parameter is set to true, then the refreshed materialized views are refreshed in a single transaction. If REGISTER_MVIEW is called multiple times with the same mviewowner, mviewname, and mviewsite, then the most recent values for mview_id, flag, and qry_txt are stored. Name of the materialized view site for a materialized view registering at an Oracle database version 8.x and higher master site or master materialized view site. Performs a process to preserve materialized view data needed for refresh, Ensures that the materialized view data for the master table is valid and that the master table is in the proper state, Estimates the size of a materialized view that you might create, in bytes and rows, Explains what is possible with a materialized view or potential materialized view, Explains why a query failed to rewrite or why the optimizer chose to rewrite a query with a particular materialized view, Returns the value of the I_AM_REFRESH package state, Returns a partition marker from a rowid, and is used for Partition Change Tracking (PCT), Purges rows from the direct loader log after they are no longer needed by any materialized views (used with data warehousing), Purges rows from the materialized view log, Refreshes one or more materialized views that are not members of the same refresh group, Refreshes all materialized views that do not reflect changes to their master table or master materialized view, Refreshes all table-based materialized views that depend on a specified master table or master materialized view, or list of master tables or master materialized views, Enables the administration of individual materialized views, Enables the administration of individual materialized views once invoked at a master site or master materialized view site to unregister a materialized view. This script creates a table named REWRITE_TABLE in the current schema. In case of an error, this procedure can be invoked again until all the materialized view logs are purged. AUTHID: CURRENT_USER: Constants Number of least recently refreshed materialized views whose rows you want to remove from materialized view log. The second version is for explaining an existing or potential materialized view with output to a VARRAY. These restrictions also apply when passing the defining query of a materialized view to the EXPLAIN_MVIEW procedure. Create the MV with the clause "REFRESH COMPLETE ON DEMAND" You don't define a refresh time when creating the MV. n > 1 specifies parallel propagation with n parallel processes. A and C are equivalent. SQL> exec dbms_mview.refresh('MY_MV',atomic_refresh=>TRUE); If you do not specify an atomic refresh (by setting "atomic refresh = FALSE" in dbms_mview.refresh_all_mviews) then you can optimize the materialized view refresh with these mechanisms: More info here: How to Refresh a Materialized View in Parallel procedure in effect for the query must return a null policy when the materialized view is being ... Note.464524.1 Ora-1555 Dbms_Refresh.Refresh or Dbms_Mview.Refresh On a Distributed Refresh: Note.258252.1 MATERIALIZED VIEW REFRESH Locking ... has occurred in the refresh code you are running. Comma-delimited list of master tables or master materialized views on which materialized views can depend. DBMS_MVIEW enables you to understand capabilities for materialized views and potential materialized views, including their rewrite availability. A and C are equivalent. or a SELECT statement or a CREATE MATERIALIZED VIEW statement for a potential materialized view. This function returns the value of the I_AM_REFRESH package state. Goal Materialized Views in Oracle. 3 Built-In Packages: 3.8 DBMS_MVIEW . Valid constants that can be assigned include the following: DBMS_MVIEW.REG_V7_SNAPSHOT if the materialized view is at an Oracle database version 7 site, DBMS_MVIEW.REG_V8_SNAPSHOT if the materialized view is at an Oracle database version 8.x or higher site, DBMS_MVIEW.REG_UNKNOWN (the default) if you do not know whether the materialized view is at an Oracle database version 7 site or an Oracle database version 8.x (or higher) site. This is an optional parameter. Query the DBA_REGISTERED_MVIEWS view at the materialized view log site to view the materialized view sites. Using the results from the procedure, you can take the appropriate action needed to make a query rewrite if at all possible. Someone might have deleted the PK after the M-View was created or it will let you create but not let you refresh it.
