DBMS_AUTO_REPORT

The DBMS_AUTO_REPORT package provides an interface to view SQL Monitoring and Real-time Automatic Database Diagnostic Monitor (ADDM) data that has been captured into Automatic Workload Repository (AWR). It also provides subprograms to control the behavior of how these data are captured to AWR.

DBMS_AUTO_REPORT Overview

This package provides an interface to view SQL Monitoring and Real-time ADDM data that has been captured into AWR. It also provides subprograms to control the behavior of how these data are captured to AWR.Captured data are stored in AWR and exposed via 2 views: DBA_HIST_REPORTS and DBA_HIST_REPORTS_DETAILS.

DBMS_AUTO_REPORT Security Model

This package is available to PUBLIC and performs its own security checking.

Summary of DBMS_AUTO_REPORT Subprograms

This table describes the parameters of the DBMS_AUTO_REPORT package subprograms.

Table 1 DBMS_AUTO_REPORT Package Subprograms

Subprogram	Description
FINISH_REPORT_CAPTURE Procedure	Ends the complete capture of SQL monitor data that was started with the START_REPORT_CAPTURE Procedure.
REPORT_REPOSITORY_DETAIL Function	Obtains the stored report for a given report ID
REPORT_REPOSITORY_DETAIL_XML Function	Obtains the stored XML report for a given report ID
REPORT_REPOSITORY_LIST_XML Function	Obtains an XML report of the list of SQL Monitor and Real-time ADDM data captured in AWR
START_REPORT_CAPTURE Procedure	Captures SQL monitor data of any newly monitored SQLs every minute since the last run of the capture cycle, and stores it in AWR.

FINISH_REPORT_CAPTURE Procedure

This procedure ends the complete capture of SQL monitor data that was started with the START_REPORT_CAPTURE procedure.

After calling this subprogram, capture of data continues every minute except that it is not captured for all active SQLs but only for those deemed important, namely the top 5 SQLs (by elapsed time, or elapsed time*DOP in case of PQ) whose monitoring has completed.

Syntax

DBMS_AUTO_REPORT.FINISH_REPORT_CAPTURE;

RETURNS XMLTYPE

Parameters

Table 4 REPORT_REPOSITORY_LIST_XML Function Parameters

Parameter	Description
`active_since`	Start of a time range used to select data. When a time range is specified, only those data are included in the list that were active during the time range. When no value is specified the time range is chosen as the last 24 hours ending at the current system time.
`active_upto`	Same as `active_since` except that it is the end of the time range
`snapshot_id`	If a value is specified, only those data captured during the specified snapshot ID are included in the list report. If no value is specified, no filtering is performed on snapshot ID.
`dbid`	If a value is specified, only those data captured for the specified database ID are included in the list report. If no value is specified, no filtering is performed on database ID
`inst_id`	If a value is specified, only those data captured on the specified instance number are included in the list report. If no value is specified, no filtering is performed on the instance ID.
`con_dbid`	If a value is specified, only those data captured on the specified container DBID are included in the list report. If no value is specified, no filtering is performed on the container DBID.
`session_id`	If a value is specified, only those data captured for the specified session ID are included in the list report. If no value is specified, no filtering is performed on session ID.
`session_serial`	If a value is specified, only those data captured for the specified session are included in the list report. If no value is specified, no filtering is performed on session serial number. This parameter should be used in conjunction with the `session_id` parameter.
`component_name`	Can be `'sqlmonitor'` for SQL Monitor data or `'rtaddm'` for Real-time ADDM data. If a value is specified then data pertaining only to the specified component will be included in the list report. If no value is specified, no filtering is performed.
`key1`	Key value relevant to a component. For SQL Monitor, `key1` is the SQL ID of the captured SQL statement. If a value is specified, only those data having specified value for `key1` are included, else no filtering is performed on `key1`.
`key2`	Key value relevant to a component. For SQL Monitor, `key2` is the SQL execution ID of the captured SQL statement. If a value is specified, only those data having specified value for `key2` are included, else no filtering is performed on `key2`.
`key3`	Key value relevant to a component. For SQL Monitor, `key3` is the SQL execution start time of the captured SQL statement. If a value is specified, then only those data having specified value for `key3` are included, else no filtering is performed on `key3`.
`report_level`	Currently only `'TYPICAL'` is used
`base_path`	Unused/Non-operative

START_REPORT_CAPTURE Procedure

This procedure captures SQL monitor data of any newly monitored SQLs every minute since the last run of the capture cycle, and stores it in AWR.

Every capture cycle attempts to capture data for SQLs that are not currently executing or queued. This is a complete capture since data of all newly monitored SQLs is captured. It continues to run every minute until it is explicitly ended with the FINISH_REPORT_CAPTURE Procedure. In the case of a RAC system, the capture will start on each node of the cluster.

Syntax

DBMS_AUTO_REPORT.START_REPORT_CAPTURE;
