Tuesday, December 29, 2020

This name should not contain any double quotes. (Synonyms are not supported.) It is invoked at a master site or master materialized view site to unregister a materialized view. It is used for Partition Change Tracking (PCT). Table 100-6 EXPLAIN_REWRITE Procedure Parameters. A demo file, xrwutl.sql, is available to help format the output from EXPLAIN_REWRITE. AUTHID: CURRENT_USER: Constants This procedure performs a process to preserve materialized view data needed for refresh. An f indicates fast refresh, ? Use this parameter to direct EXPLAIN_REWRITE's output to a PL/SQL VARRAY. Alternatively, you can specify the SELECT string or CREATE MATERIALIZED VIEW statement for a potential materialized view. Query the DBA_REGISTERED_MVIEWS view at the materialized view log site to view the materialized view names. Version of the materialized view. If a query exceeds the maximum VARCHAR2 size, then qry_txt contains the first 32000 characters of the query and the remainder is truncated. Name of the master table or master materialized view. n > 1 specifies parallel propagation with n parallel processes. 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. This procedure enables you to learn why a query failed to rewrite, or, if it rewrites, which materialized views will be used. Description. If true, then perform nested refresh operations for the specified set of tables. This procedure removes entries from the direct loader log after they are no longer needed for any known materialized view. 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 … Query the DBA_REGISTERED_MVIEWS view at the materialized view log site to view the materialized view owners. There are two ways to get the output from DBMS_MVIEW.EXPLAIN_MVIEW, via a table or via a varray. This function returns a partition marker from a rowid. A and C are equivalent. If the refresh fails for any of the materialized views, none of the materialized views are updated. Create the MV with the clause "REFRESH COMPLETE ON DEMAND" You don't define a refresh time when creating the MV. This parameter can override the setting for the parameter num. 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. 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. It is invoked at a master site or master materialized view site to unregister a materialized view. A return value of false indicates that these triggers are enabled. All of the materialized views that depend on a particular table are refreshed according to the refresh method associated with that table. 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. The first is to use a table, while the second is to create a VARRAY. This procedure is overloaded. Number of least recently refreshed materialized views whose rows you want to remove from materialized view log. This name should not contain any double quotes. Use this parameter to direct EXPLAIN_MVIEW's output to a PL/SQL VARRAY rather than MV_CAPABILITIES_TABLE. In this case, use the plus sign (+) to specify more than one property. Table 100-8 PURGE_LOG Procedure Parameters. It is invoked at a master site or master materialized view site to register a materialized view. The materialized view is in the view DBA_MVIEWS. This procedure enables you to learn what is possible with a materialized view or potential materialized view. Specify delete to guarantee that rows are deleted from the materialized view log for at least one materialized view. Goal I want to refresh a Materialized view with a a java code. Thus if we drop and then recreate the same materialized view, it will not be refreshed according to the schedule defined in the refresh group. Materialized Views in Oracle. A simple wrapper of create or replace Procedure DIM_REFRESH_MV (MV_NAME IN VARCHAR2, REFRESH_METHOD IN VARCHAR2) 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. Syntax DBMS_MVIEW.I_AM_A_REFRESH RETURN BOOLEAN; Return Values. Anyways, let's proceed and see how we can replicate and fix it. Otherwise, these changes may appear to be temporarily lost. 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. This procedure is intended for use with data warehouses. A and C are equivalent. Each package subprogram is executed by first checking the privileges against the invoker. 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 procedure refreshes a list of materialized views. For multiple materialized views, you can provide a comma-delimited list of names. P or p refreshes by recomputing the rows in the materialized view affected by changed partitions in the detail tables. 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. Note: Do not set this parameter unless directed to do so by Oracle Support Services. If all replication groups are infrequently updated and pushed, then set this parameter to 0 and occasionally execute PUSH with this parameter set to 2 to reduce the queue. 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. Set purge to aggressive to trim 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. A string of refresh methods indicating how to refresh the dependent materialized views. You can determine the properties of a materialized view by querying the ALL_MVIEWS data dictionary view. Query the DBA_BASE_TABLE_MVIEWS view at the materialized view log site for a listing of materialized view IDs. This chapter contains the following topics: This section contains topics which relate to using the DBMS_MVIEW package. Instead, I create a procedure to refresh the materialized view using dbms_mview.refresh. If this parameter is set to true, then the list of materialized views is refreshed in a single transaction. This procedure enables the administration of individual materialized views. A and C are equivalent. This procedure enables the administration of individual materialized views. So, for example, if you specify F and out_of_place = true, then an out-of-place fast refresh will be attempted. This parameter can override the setting for the parameter num. It must be called after a master table is reorganized. indicates force refresh, C or c indicates complete refresh, and A or a indicates always refresh. The EXPLAIN_REWRITE procedure cannot accept queries longer than 32627 characters. It must be called before a master table is reorganized. A and C are equivalent. -- Call Compile and Refresh in an anonymous block, completes without errors BEGIN EXECUTE IMMEDIATE 'ALTER MATERIALIZED VIEW SCHEMA1.MV_REFRESH_TEST compile'; dbms_mview.Refresh (list => 'SCHEMA1.MV_REFRESH_TEST', method => 'C'); END;-- View state of Materialized View, Still reports compilation errors Someone might have deleted the PK after the M-View was created or it will let you create but not let you refresh it. 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. 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. 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. This procedure purges rows from the materialized view log. The query parameter is a text string representing the SQL query. 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. Table 100-14 UNREGISTER_MVIEW Procedure Parameters. If this parameter is set to false, then each of the materialized views is refreshed in a separate transaction. How come there is no dbms_refresh.list to list all the mviews in a refresh group? Note that, typically, a materialized view is registered automatically during materialized view creation. DBMS_MVIEW enables you to understand capabilities for materialized views and potential materialized views, including their rewrite availability. indicates force refresh, C or c indicates complete refresh, and A or a indicates always refresh. 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. 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. The script is found in the admin directory. F or f indicates fast refresh, ? "AUD_PARTS_MVIEW"','F'); PL/SQL procedure successfully completed. P or p refreshes by recomputing the rows in the materialized view affected by changed partitions in the detail tables. Table 100-9 PURGE_MVIEW_FROM_LOG Procedure Parameters. Use procedures in the DBMS_MVIEW package to manage and refresh materialized views and their dependencies. The script is found in the ADMIN directory. If true, then it performs an out-of-place refresh. DBMS_SNAPSHOT is a synonym for DBMS_MVIEW. All of the refreshed materialized views are updated to a single point in time. When "atomic refresh" is set to TRUE (in dbms_mview.refresh_all_mviews), than the whole refresh is done in a single transaction. If this parameter is set to true, then the list of materialized views is refreshed in a single transaction. Maximum number of transactions to be examined simultaneously for parallel propagation scheduling. 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. Note that, typically, a materialized view is registered automatically during materialized view creation. Otherwise, the recommended method is to use a PL/SQL BEGIN... END block, as shown in the examples in /rdbms/demo/smxrw*. Applies to: Oracle Warehouse Builder - Version 11.2.0.1 and later Information in this document applies to any platform. DBMS_MVIEW.REFRESH_DEPENDENT ( number_of_failures OUT BINARY_INTEGER, { list IN VARCHAR2, | tab IN DBMS_UTILITY.UNCL_ARRAY,} method IN VARCHAR2 := NULL, rollback_seg IN VARCHAR2 := NULL, refresh_after_errors IN BOOLEAN := false, atomic_refresh IN BOOLEAN := true, nested IN BOOLEAN := false, out_of_place IN BOOLEAN := false); 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. The materialized view depends on a master table or master materialized view in the list of specified masters. You can obtain the output from DBMS_MVIEW.EXPLAIN_REWRITE in two ways. The identification number of the materialized view. You simply call DBMS_MVIEW.EXPLAIN_MVIEW, passing in as parameters the schema and materialized view name for an existing materialized view. Umm, I'm pretty sure that dbms_mview.refresh () is a procedure rather than a function - so there is no return value from it. The default is false. Note: Do not set this parameter unless directed to do so by Oracle Support Services. 3.8 DBMS_MVIEW. If the refresh fails for any of the materialized views, none of the materialized views are updated. If a query exceeds the maximum VARCHAR2 size, then qry_txt contains the first 32000 characters of the query and the remainder is truncated. Specify an Oracle database version 8.x and higher materialized view as a BINARY_INTEGER. The PL/SQL varray that receives the output. refresh = con.prepareStatement (str); refresh.executeQuery (); } catch (java.sql.SQLException e) {. 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 client-supplied unique identifier to distinguish output messages. All of the refreshed materialized views are updated to a single point in time. 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. Query the DBA_BASE_TABLE_MVIEWS view at the materialized view log site for a listing of materialized view IDs. F or f indicates fast refresh, ? As part of complete refresh, if truncate is used (non-atomic refresh), unique index rebuild is executed. A and C are equivalent. Name of the master table or master materialized view. Comma-delimited list of master tables or master materialized views on which materialized views can depend. 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. Table 100-10 REFRESH Procedure Parameters. Otherwise, the recommended method is to use a PL/SQL BEGIN..END block, as shown in the examples in /rdbms/demo/smxrw.sql. with a DELETE and an INSERT statement. This procedure enables the administration of individual materialized views. If you do not specify a mview_id, enter the owner of the target materialized view using the mviewowner parameter. 3 Built-In Packages: 3.8 DBMS_MVIEW . This procedure refreshes a list of materialized views. A materialized view can have more than one of these properties. A materialized view can have more than one of these properties. I will leave that up-to you to figure it out. exec dbms_mview.refresh('mviewname','c','atomic_refresh=>FALSE) is giving error Oracle 10gR2 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. The name of an existing materialized view (optionally qualified with the owner name separated by a ".") 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. I will not show you the materialized view concepts, the Oracle Datawarehouse Guide is perfect for that. Table 100-13 REGISTER_MVIEW Procedure Parameters. 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. The following shows the basic syntax for using an output table: If you want to direct the output of EXPLAIN_REWRITE to a VARRAY, instead of a table, then the procedure should be called as follows: The fully qualified name of an existing materialized view in the form of SCHEMA.MV. 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. Otherwise, the recommended method is to use a PL/SQL BEGIN..END block, as shown in the examples in /rdbms/demo/smxrw.sql. If all replication groups are infrequently updated and pushed, then set this parameter to 0 and occasionally execute PUSH with this parameter set to 2 to reduce the queue. 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. This procedure purges rows from the materialized view log. To obtain the output into a table, you must run the utlxrw.sql script before calling EXPLAIN_REWRITE. 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. The rowid of a row entry in a master table. This function returns a partition marker from a rowid. We're not taking comments currently, so please try again later if you want to add a comment. Valid constants that can be assigned include the following: DBMS_MVIEW.REG_ROWID_MVIEW for a rowid materialized view, DBMS_MVIEW.REG_PRIMARY_KEY_MVIEW for a primary key materialized view, DBMS_MVIEW.REG_OBJECT_ID_MVIEW for an object id materialized view, DBMS_MVIEW.REG_FAST_REFRESHABLE_MVIEW for a materialized view that can be fast refreshed, DBMS_MVIEW.REG_UPDATABLE_MVIEW for a materialized view that is updatable. When a master table is modified, the related materialized view becomes stale and a refresh is necessary to have the materialized view up to date. Using the results from the procedure, you can take the appropriate action needed to make a query rewrite if at all possible. In case of an error, this procedure can be invoked again until all the materialized view logs are purged. This script creates a table named REWRITE_TABLE in the current schema. In contrary of views, materialized views avoid executing the SQL query for every access by storing the result set of the query. Used by updatable materialized views only. 1 specifies parallel propagation using only one parallel process. The first 32,000 bytes of the materialized view definition query. Maximum number of transactions to be examined simultaneously for parallel propagation scheduling. When it is not specified, EXPLAIN_REWRITE returns any relevant messages regarding all the materialized views considered for rewriting the given query. If this parameter is true, an updatable materialized view continues to refresh even if there are outstanding conflicts logged in the DEFERROR view for the materialized view's master table or master materialized view. Otherwise, an insufficient privileges error will be thrown. You should only run this procedure to manually register a materialized view if the automatic registration failed or if the registration information was deleted.
