Overview

Database auditing helps meet your database security and compliance requirements. Audit records are written to database tables, operating system (OS) files, or XML files depending on the AUDIT_TRAIL initialization parameter setting.

When AUDIT_TRAIL is set to DB, database records are written to the AUD$ and FGA_LOG$ tables in the SYSTEM tablespace. When AUDIT_TRAIL is set to OS, audit records are written to operating system files. When AUDIT_TRAIL is set to XML, audit records are written to operating system files in XML format.

Oracle Database Security Guide for more background information on database auditing

It is important to manage your audit records properly in order to ensure efficient auditing and clean up.The DBMS_AUDIT_MGMT subprograms enable you to efficiently manage your audit trail records.

The DBMS_AUDIT_MGMT package provides a subprogram that allows you to move the database audit trail tables out of the SYSTEM tablespace. This improves overall database performance. It also allows you to dedicate an optimized tablespace for audit records.

The DBMS_AUDIT_MGMT subprograms also enable you to manage your operating system and XML audit records. You can define properties like the maximum size and age of an audit file. New audit files are automatically created once the maximum limits are reached.

The DBMS_AUDIT_MGMT subprograms enable you to perform cleanup operations on all audit trail types. Audit trail records can be deleted based on their last archive timestamp. The last archive timestamp indicates when the audit records were last archived.

The DBMS_AUDIT_MGMT package provides a subprogram that enables audit administrators to set the last archive timestamp for archived audit records. This subprogram can also be used by external archival systems to set the last archive timestamp.

The DBMS_AUDIT_MGMT subprograms also enable you to configure jobs that periodically delete audit trail records. The frequency with which these jobs should run can be controlled by the audit administrator.

Security Model

All DBMS_AUDIT_MGMT subprograms require the user to have EXECUTE privilege over the DBMS_AUDIT_MGMT package. The SYSDBA role has EXECUTE privileges on the package by default.

Only audit administrators should have EXECUTE privileges over the DBMS_AUDIT_MGMT package.

Constants

The DBMS_AUDIT_MGMT package defines several enumerated constants that should be used for specifying parameter values. Enumerated constants must be prefixed with the package name, for example, DBMS_AUDIT_MGMT.AUDIT_TRAIL_AUD_STD.

The DBMS_AUDIT_MGMT package uses the constants shown in the following tables:

DBMS_AUDIT_MGMT Constants - Audit Trail Types
DBMS_AUDIT_MGMT Constants - Audit Trail Properties
DBMS_AUDIT_MGMT Constants - Purge Job Status
DBMS_AUDIT_MGMT Constants - Trace Level Values

Audit trails can be classified based on whether audit records are written to database tables, operating system files, or XML files. Table G-1 lists the audit trail type constants.

CLEAN_AUDI T_TRAIL Procedure

This procedure deletes audit trail records that have been archived.

The CLEAN_AUDIT_TRAIL procedure is usually called after the SET_LAST_ARCHIVE_TIMESTAMP Procedure has been used to set the last archived timestamp for the audit records.

Syntax

DBMS_AUDIT_MGMT.CLEAN_AUDIT_TRAIL(
   audit_trail_type         IN PLS_INTEGER,
   use_last_arch_timestamp  IN BOOLEAN DEFAULT TRUE) ;

Parameters

Table G-9 CLEAN_AUDIT_TRAIL Procedure Parameters

Parameter Description

Parameter	Description
`audit_trail_type`	The audit trail type for which the cleanup operation needs to be performed. Audit trail types are listed in Table G-1, "DBMS_AUDIT_MGMT Constants - Audit Trail Types" .
`use_last_arch_timestamp`	Specifies whether the last archived timestamp should be used for deciding on the records that should be deleted. A value of `TRUE` indicates that only audit records created before the last archive timestamp should be deleted. A value of `FALSE` indicates that all audit records should be deleted. The default value is `TRUE`.

audit_trail_type

The audit trail type for which the cleanup operation needs to be performed. Audit trail types are listed in Table G-1, "DBMS_AUDIT_MGMT Constants - Audit Trail Types" .

use_last_arch_timestamp

Specifies whether the last archived timestamp should be used for deciding on the records that should be deleted.

A value of TRUE indicates that only audit records created before the last archive timestamp should be deleted.

A value of FALSE indicates that all audit records should be deleted.

The default value is TRUE.

Examples

The following example calls the CLEAN_AUDIT_TRAIL procedure to clean up the operating system (OS) audit trail records that were created before the last archive timestamp.

BEGIN
DBMS_AUDIT_MGMT.CLEAN_AUDIT_TRAIL(
   audit_trail_type => DBMS_AUDIT_MGMT.AUDIT_TRAIL_OS,
   use_last_arch_timestamp => TRUE);
END;
/

CLEAR_AUDIT_TRAIL_P ROPERTY Procedure

This procedure clears the value for the audit trail property that is specified. Audit trail properties are set using the SET_AUDIT_TRAIL_PROPERTY Procedure.

The CLEAR_AUDIT_TRAIL_PROPERTY procedure can optionally reset the property value to it's default value through the use_default_values parameter.

Syntax

DBMS_AUDIT_MGMT.CLEAR_AUDIT_TRAIL_PROPERTY(
   audit_trail_type        IN PLS_INTEGER,
   audit_trail_property    IN PLS_INTEGER,
   use_default_values      IN BOOLEAN DEFAULT FALSE) ;

Parameters

Table G-10 CLEAR_AUDIT_TRAIL_PROPERTY Procedure Parameters

Parameter Description

Parameter	Description
`audit_trail_type`	The audit trail type for which the property needs to be cleared. Audit trail types are listed in Table G-1, "DBMS_AUDIT_MGMT Constants - Audit Trail Types"
`audit_trail_property`	The audit trail property whose value needs to be cleared. You cannot clear the value for the `CLEANUP_INTERVAL` property. Audit trail properties are listed in Table G-2, "DBMS_AUDIT_MGMT Constants - Audit Trail Properties"
`use_default_values`	Specifies whether the default value of the `audit_trail_property` should be used in place of the cleared value. A value of `TRUE` causes the default value of the parameter to be used. A value of `FALSE` causes the `audit_trail_property` to have no value. The default value for this parameter is `FALSE`.

audit_trail_type

The audit trail type for which the property needs to be cleared. Audit trail types are listed in Table G-1, "DBMS_AUDIT_MGMT Constants - Audit Trail Types"

audit_trail_property

The audit trail property whose value needs to be cleared. You cannot clear the value for the CLEANUP_INTERVAL property.

Audit trail properties are listed in Table G-2, "DBMS_AUDIT_MGMT Constants - Audit Trail Properties"

use_default_values

Specifies whether the default value of the audit_trail_property should be used in place of the cleared value. A value of TRUE causes the default value of the parameter to be used. A value of FALSE causes the audit_trail_property to have no value.

The default value for this parameter is FALSE.

Usage Notes

The following usage notes apply:

You can use this procedure to clear the value for an audit trail property that you do not wish to use. For example, if you do not want a restriction on the operating system audit file size, then you can use this procedure to reset the OS_FILE_MAX_SIZE property.

You can also use this procedure to reset an audit trail property to it's default value. You need to set use_default_values to TRUE when invoking the procedure.
The DB_DELETE_BATCH_SIZE property needs to be individually cleared for the AUDIT_TRAIL_AUD_STD and AUDIT_TRAIL_FGA_STD audit trail types. You cannot clear this property collectively using the AUDIT_TRAIL_DB_STD and AUDIT_TRAIL_ALL audit trail types.
You cannot clear the value for the CLEANUP_INTERVAL property.

Examples

The following example calls the CLEAR_AUDIT_TRAIL_PROPERTY procedure to clear the value for the audit trail property, OS_FILE_MAX_SIZE. The procedure uses a value of FALSE for the USE_DEFAULT_VALUES parameter. This means that the OS_FILE_MAX_SIZE property will no longer determine the size of the operating system (OS) audit files.

BEGIN
DBMS_AUDIT_MGMT.CLEAR_AUDIT_TRAIL_PROPERTY(
   AUDIT_TRAIL_TYPE        =>  DBMS_AUDIT_MGMT.AUDIT_TRAIL_OS,
   AUDIT_TRAIL_PROPERTY    =>  DBMS_AUDIT_MGMT.OS_FILE_MAX_SIZE,
   USE_DEFAULT_VALUES      =>  FALSE );
END;
/

CLEAR_LAST_ARCHI VE_TIMESTAMP Procedure

This procedure clears the timestamp set by the SET_LAST_ARCHIVE_TIMESTAMP Procedure.

Syntax

DBMS_AUDIT_MGMT.CLEAR_LAST_ARCHIVE_TIMESTAMP(
   audit_trail_type     IN PLS_INTEGER,

`rac_instance_number`	The instance number for the Oracle Real Application Clusters (RAC) instance. The default value is 0, which is used for the database audit trail type. The `rac_instance_number` is not relevant for the database audit trail type, as the database audit trail tables are shared by all RAC instances.

audit_trail_type

The audit trail type for which the timestamp needs to be cleared. Audit trail types are listed in Table G-1, "DBMS_AUDIT_MGMT Constants - Audit Trail Types" .

rac_instance_number

The instance number for the Oracle Real Application Clusters (RAC) instance. The default value is 0, which is used for the database audit trail type.

The rac_instance_number is not relevant for the database audit trail type, as the database audit trail tables are shared by all RAC instances.

Examples

The following example calls the CLEAR_LAST_ARCHIVE_TIMESTAMP procedure to clear the timestamp value for the operating system (OS) audit trail type.

BEGIN
DBMS_AUDIT_MGMT.CLEAR_LAST_ARCHIVE_TIMESTAMP(
   audit_trail_type     =>  DBMS_AUDIT_MGMT.AUDIT_TRAIL_OS,
   rac_instance_number  =>  1 /* single instance database */);
END;
/

CREATE_PURGE_J OB Procedure

This procedure creates a purge job for periodically deleting the audit trail records. The procedure can use the timestamp value set by the SET_LAST_ARCHIVE_TIMESTAMP Procedure to decide upon the records to be deleted.

This procedure carries out the cleanup operation at intervals specified by the user. It calls the CLEAN_AUDIT_TRAIL Procedure to perform the cleanup operation.

The SET_PURGE_JOB_INTERVAL Procedure is used to modify the frequency of the purge job.

The SET_PURGE_JOB_STATUS Procedure is used to enable or disable the purge job.

The DROP_PURGE_JOB Procedure is used to drop a purge job created with the CREATE_PURGE_JOB procedure.

Syntax

DBMS_AUDIT_MGMT.CREATE_PURGE_JOB(
   audit_trail_type            IN PLS_INTEGER,
   audit_trail_purge_interval  IN PLS_INTEGER,
   audit_trail_purge_name      IN VARCHAR2,
   use_last_arch_timestamp     IN BOOLEAN DEFAULT TRUE) ;

Parameters

Table G-12 CREATE_PURGE_JOB Procedure Parameters

Parameter	Description
`audit_trail_type`	The audit trail type for which the purge job needs to be created. Audit trail types are listed in Table G-1, "DBMS_AUDIT_MGMT Constants - Audit Trail Types" .
`audit_trail_purge_interval`	The interval, in hours, at which the clean up procedure is called. A lower value means that the cleanup is performed more often.
`audit_trail_purge_name`	A name to identify the purge job.
`use_last_arch_timestamp`	Specifies whether the last archived timestamp should be used for deciding on the records that should be deleted. A value of `TRUE` indicates that only audit records created before the last archive timestamp should be deleted. A value of `FALSE` indicates that all audit records should be deleted. The default value is `TRUE`.

Usage Notes

Use this procedure to schedule the CLEAN_AUDIT_TRAIL Procedure for your audit records.

Examples

The following example calls the CREATE_PURGE_JOB procedure to create a cleanup job called CLEANUP, for all audit trail types. It sets the audit_trail_purge_interval parameter to 100. This means that the cleanup job is invoked every 100 hours. It also sets the use_last_arch_timestamp parameter value to TRUE. This means that all audit records older than the last archive timestamp are deleted.

BEGIN
DBMS_AUDIT_MGMT.CREATE_PURGE_JOB(
  audit_trail_type => DBMS_AUDIT_MGMT.AUDIT_TRAIL_ALL,
  audit_trail_purge_interval => 100 /* hours */,  
  audit_trail_purge_name => 'CLEANUP',
  use_last_arch_timestamp => TRUE);
END;
/

DEINIT_CLEANUP Proc edure

This procedure undoes the setup and initialization performed by the INIT_CLEANUP Procedure. The DEINIT_CLEANUP procedure clears the value of the default_cleanup_interval parameter. However, it does not move the audit trail tables back to their original location.

Syntax

DBMS_AUDIT_MGMT.DEINIT_CLEANUP(
   audit_trail_type  IN PLS_INTEGER) ;

Parameters

Table G-13 DEINIT_CLEANUP Procedure Parameters

Parameter Description

Parameter	Description
`audit_trail_type`	The audit trail type for which the procedure needs to be called. Audit trail types are listed in Table G-1, "DBMS_AUDIT_MGMT Constants - Audit Trail Types"

audit_trail_type

The audit trail type for which the procedure needs to be called.

Audit trail types are listed in Table G-1, "DBMS_AUDIT_MGMT Constants - Audit Trail Types"

Usage Notes

You can change the default_cleanup_interval later using the SET_AUDIT_TRAIL_PROPERTY Procedure.

Examples

The following example clears the default_cleanup_interval parameter setting for the standard database audit trail:

BEGIN
DBMS_AUDIT_MGMT.DEINIT_CLEANUP(
  AUDIT_TRAIL_TYPE  => DBMS_AUDIT_MGMT.AUDIT_TRAIL_AUD_STD);
END;
/

DROP_PURGE_JOB Pro cedure

This procedure drops the purge job created using the CREATE_PURGE_JOB Procedure. The name of the purge job is passed as an argument.

Syntax

DBMS_AUDIT_MGMT.DROP_PURGE_JOB(
   audit_trail_purge_name    IN VARCHAR2) ;

Parameters

Table G-14 DROP_PURGE_JOB Procedure Parameters

Parameter	Description
`audit_trail_`purge_name	The name of the purge job which is being deleted. This is the purge job name that you specified with the CREATE_PURGE_JOB Procedure.

Examples

The following example calls the DROP_PURGE_JOB procedure to drop the purge job called CLEANUP.

BEGIN
DBMS_AUDIT_MGMT.DROP_PURGE_JOB(
  AUDIT_TRAIL_PURGE_NAME  => 'CLEANUP');
END;
/

GET_AUDIT_COMMIT_DELAY Function

This function returns the Audit COMMIT Delay as the number of seconds. Audit COMMIT Delay is the maximum time that it takes to COMMIT an audit record to the database audit trail. If it takes more time to COMMIT an audit record than defined by the Audit COMMIT Delay, then the audit record is written to the operating system (OS) audit trail.

The Audit COMMIT Delay value is useful when determining the last archive timestamp for database audit records.

Syntax

DBMS_AUDIT_MGMT.GET_AUDIT_COMMIT_DELAY
  RETURN NUMBER;

INIT_CLEANUP Pr ocedure

This procedure sets up the audit management infrastructure and a default cleanup interval for the audit trail records. The procedure also moves the audit trail tables out of the SYSTEM tablespace.

Moving the audit trail tables out of the SYSTEM tablespace enhances overall database performance. The INIT_CLEANUP procedure moves the audit trail tables to the SYSAUX tablespace. If the SET_AUDIT_TRAIL_LOCATION Procedure has already moved the audit tables elsewhere, then they are not moved back to the SYSAUX tablespace.

The SET_AUDIT_TRAIL_LOCATION Procedure enables you to specify an alternate target tablespace for the database audit tables.

The INIT_CLEANUP procedure is currently not relevant for the AUDIT_TRAIL_OS, AUDIT_TRAIL_XML, and AUDIT_TRAIL_FILES audit trail types. No preliminary set up is required for these audit trail types.

See Also:

Table G-1, "DBMS_AUDIT_MGMT Constants - Audit Trail Types" for a list of all audit trail types

This procedure also sets a default cleanup interval for the audit trail records.

Syntax

DBMS_AUDIT_MGMT.INIT_CLEANUP(
   audit_trail_type          IN PLS_INTEGER,
   default_cleanup_interval  IN PLS_INTEGER);

Parameters

Table G-15 INIT_CLEANUP Procedure Parameters

Parameter Description

Parameter	Description
`audit_trail_type`	The audit trail type for which the clean up operation needs to be initialized. Audit trail types are listed in Table G-1, "DBMS_AUDIT_MGMT Constants - Audit Trail Types"
`default_cleanup_interval`	The default time interval, in hours, after which the cleanup procedure should be called. The minimum value is 1 and the maximum is 999.

audit_trail_type

The audit trail type for which the clean up operation needs to be initialized.

Audit trail types are listed in Table G-1, "DBMS_AUDIT_MGMT Constants - Audit Trail Types"

default_cleanup_interval

The default time interval, in hours, after which the cleanup procedure should be called. The minimum value is 1 and the maximum is 999.

Usage Notes

The following usage notes apply:

This procedure may involve data movement across tablespaces. This can be a resource intensive operation especially if your database audit trail tables are already populated. Oracle recommends that you invoke the procedure during non-peak hours.
You should ensure that the SYSAUX tablespace, into which the audit trail tables are being moved, has sufficient space to accommodate the audit trail tables. You should also optimize the SYSAUX tablespace for frequent write operations.
You can change the default_cleanup_interval later using the SET_AUDIT_TRAIL_PROPERTY Procedure.

Examples

The following example calls the INIT_CLEANUP procedure to set a default_cleanup_interval of 12 hours for all audit trail types:

BEGIN
DBMS_AUDIT_MGMT.INIT_CLEANUP(
              audit_trail_type => DBMS_AUDIT_MGMT.AUDIT_TRAIL_ALL,
      default_cleanup_interval => 12 /* hours */);
END;
/

See Also:

Table G-1, "DBMS_AUDIT_MGMT Constants - Audit Trail Types" for a list of all audit trail types

IS_CLEANUP_INITIAL IZED Function

This function checks to see if the INIT_CLEANUP Procedure has been run for an audit trail type. The IS_CLEANUP_INITIALIZED function returns TRUE if the procedure has already been run for the audit trail type. It returns FALSE if the procedure has not been run for the audit trail type.

This function is currently not relevant for the AUDIT_TRAIL_OS, AUDIT_TRAIL_XML, and AUDIT_TRAIL_FILES audit trail types. The function always returns TRUE for these audit trail types. No preliminary set up is required for these audit trail types.

See Also:

Table G-1, "DBMS_AUDIT_MGMT Constants - Audit Trail Types" for a list of all audit trail types

Syntax

DBMS_AUDIT_MGMT.DEINIT_CLEANUP(
   audit_trail_type  IN PLS_INTEGER)
 RETURN BOOLEAN;

Parameters

Table G-16 IS_CLEANUP_INITIALIZED Function Parameters

Parameter Description

Parameter	Description
`audit_trail_type`	The audit trail type for which the function needs to be called. Audit trail types are listed in Table G-1, "DBMS_AUDIT_MGMT Constants - Audit Trail Types"

audit_trail_type

The audit trail type for which the function needs to be called.

Audit trail types are listed in Table G-1, "DBMS_AUDIT_MGMT Constants - Audit Trail Types"

Examples

The following example checks to see if the standard database audit trail type has been initialized for cleanup operation. If the audit trail type has not been initialized, then it calls the INIT_CLEANUP Procedure to initialize the audit trail type.

BEGIN
 IF 
   NOT DBMS_AUDIT_MGMT.IS_CLEANUP_INITIALIZED(DBMS_AUDIT_MGMT.AUDIT_TRAIL_AUD_STD)
 THEN
   DBMS_AUDIT_MGMT.INIT_CLEANUP(
      audit_trail_type => DBMS_AUDIT_MGMT.AUDIT_TRAIL_AUD_STD,
      default_cleanup_interval => 12 /* hours */);
 END IF;
END;
/

SET_AUDIT_TRAIL_LOC ATION Procedure

This procedure moves the audit trail tables from their current tablespace to a user-specified tablespace.

The SET_AUDIT_TRAIL_LOCATION procedure is currently not relevant for the AUDIT_TRAIL_OS, AUDIT_TRAIL_XML, and AUDIT_TRAIL_FILES audit trail types. The AUDIT_FILE_DEST initialization parameter can be used to specify the destination directory for these audit trail types.

See Also:

Table G-1, "DBMS_AUDIT_MGMT Constants - Audit Trail Types" for a list of all audit trail types

Syntax

DBMS_AUDIT_MGMT.SET_AUDIT_TRAIL_LOCATION(
   audit_trail_type            IN PLS_INTEGER,
   audit_trail_location_value  IN VARCHAR2) ;

Parameters

Table G-17 SET_AUDIT_TRAIL_LOCATION Procedure Parameters

Parameter Description

Parameter	Description
`audit_trail_type`	The audit trail type for which the audit trail location needs to be set. Audit trail types are listed in Table G-1, "DBMS_AUDIT_MGMT Constants - Audit Trail Types"
`audit_trail_location_value`	The target location/tablespace for the audit trail records

audit_trail_type

The audit trail type for which the audit trail location needs to be set.

Audit trail types are listed in Table G-1, "DBMS_AUDIT_MGMT Constants - Audit Trail Types"

audit_trail_location_value

The target location/tablespace for the audit trail records

Usage Notes

The following usage notes apply:

This procedure involves data movement across tablespaces. This can be a resource intensive operation especially if your database audit trail tables are already populated. Oracle recommends that you invoke the procedure during non-peak hours.
You should ensure that the target tablespace, into which the audit trail tables are being moved, has sufficient space to accommodate the audit trail tables. You should also optimize the target tablespace for frequent write operations.

Examples

The following example moves the database audit trail tables, AUD$ and FGA_LOG$, from the current tablespace to a user-created tablespace called RECORDS:

BEGIN
DBMS_AUDIT_MGMT.SET_AUDIT_TRAIL_LOCATION(
       audit_trail_type => DBMS_AUDIT_MGMT.AUDIT_TRAIL_DB_STD,
       audit_trail_location_value =>  'RECORDS');
END;
/

SET_AUDIT_TRAIL_PROP ERTY Procedure

This procedure sets the audit trail properties for the audit trail type that is specified.

The procedure sets properties like OS_FILE_MAX_SIZE and OS_FILE_MAX_AGE for operating system (OS) and XML audit trail types. These properties determine the maximum size and age of an audit trail file before a new audit trail file gets created.

The procedure sets properties like DB_DELETE_BATCH_SIZE and CLEANUP_INTERVAL for the database audit trail type. DB_DELETE_BATCH_SIZE specifies the batch size in which records get deleted from audit trail tables. This ensures that if a cleanup operation gets interrupted midway, the process does not need to start afresh the next time it is invoked. This is because all batches before the last processed batch are already deleted.

The CLEANUP_INTERVAL specifies the frequency, in hours, with which the cleanup procedure is called.

Syntax

DBMS_AUDIT_MGMT.SET_AUDIT_TRAIL_PROPERTY(
   audit_trail_type            IN PLS_INTEGER,
   audit_trail_property        IN PLS_INTEGER,
   audit_trail_property_value  IN PLS_INTEGER) ;

Parameters

Table G-18 SET_AUDIT_TRAIL_PROPERTY Procedure Parameters

Parameter Description

Usage Notes

The following usage notes apply:

The audit trail properties for which you do not explicitly set values use their default values.
If you have set both the OS_FILE_MAX_SIZE and OS_FILE_MAX_AGE properties for an operating system (OS) or XML audit trail type, then a new audit trail file gets created depending on which of these two limits is reached first.

For example, let us take a scenario where OS_FILE_MAX_SIZE is 10000 and OS_FILE_MAX_AGE is 5. If the operating system audit file is already more than 5 days old and has a size of 9000 KB, then a new audit file is opened. This is because one of the limits has been reached.
The DB_DELETE_BATCH_SIZE property needs to be individually set for the AUDIT_TRAIL_AUD_STD and AUDIT_TRAIL_FGA_STD audit trail types. You cannot set this property collectively using the AUDIT_TRAIL_DB_STD and AUDIT_TRAIL_ALL audit trail types.

Examples

The following example calls the SET_AUDIT_TRAIL_PROPERTY procedure to set the OS_FILE_MAX_SIZE property for the operating system (OS) audit trail. It sets this property value to 102400. This means that a new audit file gets created every time the current audit file size reaches 100 MB.

BEGIN
DBMS_AUDIT_MGMT.SET_AUDIT_TRAIL_PROPERTY(
       audit_trail_type => DBMS_AUDIT_MGMT.AUDIT_TRAIL_OS,
       audit_trail_property  =>  DBMS_AUDIT_MGMT.OS_FILE_MAX_SIZE,
       audit_trail_property_value =>  102400 /* 100MB*/ );
END;
/

The following example calls the SET_AUDIT_TRAIL_PROPERTY procedure to set the OS_FILE_MAX_AGE property for the operating system (OS) audit trail. It sets this property value to 5. This means that a new audit file gets created every sixth day.

BEGIN
DBMS_AUDIT_MGMT.SET_AUDIT_TRAIL_PROPERTY(
       audit_trail_type => DBMS_AUDIT_MGMT.AUDIT_TRAIL_OS,
       audit_trail_property  =>  DBMS_AUDIT_MGMT.OS_FILE_MAX_AGE,
       audit_trail_property_value  =>  5 /* days */);
END;
/

The following example calls the SET_AUDIT_TRAIL_PROPERTY procedure to set the DB_DELETE_BATCH_SIZE property for the AUDIT_TRAIL_AUD_STD audit trail. It sets this property value to 100000. This means that during a cleanup operation, audit records are deleted from the SYS.AUD$ table in batches of size 100000.

BEGIN
DBMS_AUDIT_MGMT.SET_AUDIT_TRAIL_PROPERTY(
       audit_trail_type => DBMS_AUDIT_MGMT.AUDIT_TRAIL_AUD_STD,
       audit_trail_property => DBMS_AUDIT_MGMT.DB_DELETE_BATCH_SIZE,
       audit_trail_property_value => 100000 /* delete batch size */);
END;
/

SET_DEBUG_L EVEL Procedure

This procedure sets the trace level for the DBMS_AUDIT_MGMT package. The default trace level, TRACE_LEVEL_ERROR, logs only the error messages as trace messages. The debug trace level, TRACE_LEVEL_DEBUG, logs detailed debug messages.

Syntax

DBMS_AUDIT_MGMT.SET_DEBUG_LEVEL(
   debug_level IN PLS_INTEGER DEFAULT TRACE_LEVEL_ERROR);

Parameters

Table G-19 SET_DEBUG_LEVEL Procedure Parameters

Parameter Description

Parameter	Description
debug_level	The trace level to set. `TRACE_LEVEL_ERROR` logs only the error messages as trace messages. `TRACE_LEVEL_DEBUG` logs detailed debug messages.

debug_level

The trace level to set.

TRACE_LEVEL_ERROR logs only the error messages as trace messages. TRACE_LEVEL_DEBUG logs detailed debug messages.

Examples

The following example calls the SET_DEBUG_LEVEL procedure to enable enhanced debugging.

BEGIN
DBMS_AUDIT_MGMT.SET_DEBUG_LEVEL(
  debug_level   => DBMS_AUDIT_MGMT.TRACE_LEVEL_DEBUG);
END;
/

SET_LAST_ARCHIVE_TIMEST AMP Procedure

This procedure sets a timestamp indicating when the audit records were last archived. The audit administrator provides the timestamp to be attached to the audit records. The CLEAN_AUDIT_TRAIL Procedure uses this timestamp to decide on the audit records to be deleted.

Syntax

DBMS_AUDIT_MGMT.SET_LAST_ARCHIVE_TIMESTAMP(
   audit_trail_type     IN PLS_INTEGER,
   last_archive_time    IN TIMESTAMP,
   rac_instance_number  IN PLS_INTEGER DEFAULT 0) ;

Parameters

Table G-20 SET_LAST_ARCHIVE_TIMESTAMP Procedure Parameters

Parameter Description

Parameter	Description
`audit_trail_type`	The audit trail type for which the timestamp needs to be set. Audit trail types are listed in Table G-1, "DBMS_AUDIT_MGMT Constants - Audit Trail Types" .
`last_archive_time`	The `TIMESTAMP` value to be attached to the audit records. This indicates the last time when the audit records were archived.
`rac_instance_number`	The instance number for the Oracle Real Application Clusters (RAC) instance.The default value is 0, which is used for the database audit trail type. The `rac_instance_number` is not relevant for the database audit trail type, as the database audit trail tables are shared by all RAC instances.

audit_trail_type

The audit trail type for which the timestamp needs to be set. Audit trail types are listed in Table G-1, "DBMS_AUDIT_MGMT Constants - Audit Trail Types" .

last_archive_time

The TIMESTAMP value to be attached to the audit records. This indicates the last time when the audit records were archived.

rac_instance_number

The instance number for the Oracle Real Application Clusters (RAC) instance.The default value is 0, which is used for the database audit trail type.

The rac_instance_number is not relevant for the database audit trail type, as the database audit trail tables are shared by all RAC instances.

Usage Notes

The following usage notes apply:

The last_archive_time must be specified in Coordinated Universal Time (UTC) when the audit trail types are AUDIT_TRAIL_AUD_STD or AUDIT_TRAIL_FGA_STD. This is because the database audit trails store the timestamps in UTC. UTC is also known as Greenwich Mean Time (GMT).
The last_archive_time must be specified as the local timezone time when the audit trail types are AUDIT_TRAIL_OS or AUDIT_TRAIL_XML. This is because the operating system audit records are stored as files that use the local timezone for their last modification timestamps.
When using an Oracle Real Application Clusters (RAC) database, Oracle recommends that you use the Network Time Protocol (NTP) to synchronize individual RAC nodes.

Examples

The following example calls the SET_LAST_ARCHIVE_TIMESTAMP procedure to set the last archive timestamp for the operating system (OS) audit trail type. It uses the TO_TIMESTAMP function to convert a character string into a timestamp value.

BEGIN
DBMS_AUDIT_MGMT.SET_LAST_ARCHIVE_TIMESTAMP(
   audit_trail_type => DBMS_AUDIT_MGMT.AUDIT_TRAIL_OS,
   last_archive_time => TO_TIMESTAMP('10-SEP-0714:10:10.0','DD-MON-RRHH24:MI:SS.FF'),
   rac_instance_number => 1 /* single instance database */);
END;
