fine grained audit policy, you use the DBMSFGA PLSQL package.This package enables you to add all combinations of SELECT, INSERT, UPDATE, and DELETE statements to one policy.Image/8f937631df351710557a351d77504e1a/paas_dbaas_uname.png' alt='Oracle Virtual Directory Installation Guide 11 Gmt' title='Oracle Virtual Directory Installation Guide 11 Gmt' />You also can audit MERGE statements, by auditing the underlying actions of INSERT and UPDATE.To audit MERGE statements, configure fine grained access on the INSERT and UPDATE statements.Only one record is generated for each policy for successful MERGE operations.To administer fine grained audit policies, you must have the EXECUTE privilege on the DBMSFGA package.The audit policy is bound to the table for which you created it.This simplifies the management of audit policies because the policy only must be changed once in the database, not in each application.In addition, no matter how a user connects to the databasefrom an application, a Web interface, or through SQLPlus or Oracle SQL DeveloperOracle Database records any actions that affect the policy.If any rows returned from a query match the audit condition that you define, then Oracle Database inserts an audit entry into the fine grained audit trail.This entry excludes all the information that is reported in the regular audit trail.In other words, only one row of audit information is inserted into the audit trail for every fine grained audit policy that evaluates to true.For detailed information about the syntax of the DBMSFGA package, see Oracle Database PLSQL Packages and Types Reference.See also Oracle Database Advanced Application Developers Guide.Creating a Fine Grained Audit Policy.To create a fine grained audit policy, use the DBMSFGA.ADDPOLICY procedure.This procedure creates an audit policy using the supplied predicate as the audit condition.Oracle Database executes the policy predicate with the privileges of the user who created the policy.The maximum number of fine grained policies on any table or view object is 2.Oracle Database stores the policy in the data dictionary table, but you can create the policy on any table or view that is not in the SYS schema.Ruby Quick Guide Learn Ruby in simple and easy steps starting from basic to advanced concepts with examples including Overview, Environment Setup, Syntax, Classes.After you create the fine grained audit policy, it does not reside in any specific schema, although the definition for the policy is stored in the SYS.FGA data dictionary table.You cannot modify a fine grained audit policy after you have created it.If you need to modify the policy, drop it and then recreate it.Be aware that if a table column has a fine grained audit policy, you cannot encrypt or decrypt this column by using the UPDATE statement.To do so raises an ORA 2.If you want to update the column, first temporarily disable the fine grained audit policy and then encrypt or decrypt the column.Afterwards, re enable the fine grained audit policy.See Disabling and Enabling a Fine Grained Audit Policy for more information.Install Cutepdf Without Admin Rights In Windows there.The syntax for the ADDPOLICY procedure is.DBMSFGA.ADDPOLICY.VARCHAR2.VARCHAR2.VARCHAR2.VARCHAR2.VARCHAR2.VARCHAR2.VARCHAR2.BOOLEAN.VARCHAR2.BINARYINTEGER IN DEFAULT.BINARYINTEGER IN DEFAULT.In this specification objectschema Specifies the schema of the object to be audited.If NULL, the current log on user schema is assumed.Specifies the name of the object to be audited.Specifies the name of the policy to be created.Ensure that this name is unique.Specifies a Boolean condition in a row.NULL is allowed and acts as TRUE.See Auditing Specific Columns and Rows for more information.If you specify NULL or no audit condition, then any action on a table with that policy creates an audit record, whether or not rows are returned.Follow these guidelines Do not include functions, which execute the auditable statement on the same base table, in the auditcondition setting.For example, suppose you create a function that executes an INSERT statement on the HR.EMPLOYEES table.The policys auditcondition contains this function and it is for INSERT statements as set by statementtypes.When the policy is used, the function executes recursively until the system has run out of memory.This can raise the error.ORA 1.ORA 0. 00. 36 maximum number of recursive SQL levels 5.Do not issue the DBMSFGA.ENABLEPOLICY or DBMSFGA.DISABLEPOLICY statement from a function in a policys condition.Specifies one or more columns to audit, including hidden columns.If set to NULL or omitted, all columns are audited.These can include Oracle Label Security hidden columns or object type columns.The default, NULL, causes audit if any column is accessed or affected.If an alert is used to trigger a response when the policy is violated, specifies the name of the schema that contains the event handler.The default, NULL, uses the current schema.See also Tutorial Adding an Email Alert to a Fine Grained Audit Policy.Specifies the name of the event handler.Include the package the event handler is in.This function is invoked only after the first row that matches the audit condition in the query is processed.Follow these guidelines Do not create recursive fine grained audit handlers.For example, suppose you create a handler that executes an INSERT statement on the HR.EMPLOYEES table.The policy that is associated with this handler is for INSERT statements as set by the statementtypes parameter.When the policy is used, the handler executes recursively until the system has run out of memory.This can raise the error.ORA 1.ORA 0. 00. 36 maximum number of recursive SQL levels 5.Do not issue the DBMSFGA.ENABLEPOLICY or DBMSFGA.DISABLEPOLICY statement from a policy handler.Doing so can raise the.ORA 2.Failed to execute fine grained audit handler error.Enables or disables the policy using true or false.If omitted, the policy is enabled.The default is TRUE.Specifies the SQL statements to be audited INSERT, UPDATE, DELETE, or SELECT only.The default is SELECT.Specifies the destination DB or XML of fine grained audit records.Also specifies whether to populate LSQLTEXT and LSQLBIND in FGALOG.However, be aware that sensitive data, such as credit card information, can be recorded in clear text.See Auditing Sensitive Information for how you can handle this scenario.If you set the audittrail parameter to XML, then the XML files are written to the directory specified by the AUDITFILEDEST initialization parameter.For read only databases, Oracle Database writes the fine grained audit trail to XML files, regardless of the audittrail setting.If you specify more than one column in the auditcolumn parameter, then this parameter determines whether to audit all or specific columns.See Auditing Specific Columns and Rows for more information.See Oracle Database PLSQL Packages and Types Reference for additional details about the ADDPOLICY syntax.Example 9 2.INSERT, UPDATE, DELETE, and SELECT on table HR.EMPLOYEES.Note that this example omits the auditcolumnopts parameter, because it is not a mandatory parameter.Example 9 2.Using DBMSFGA.ADDPOLICY to Create a Fine Grained Audit Policy.DBMSFGA.

At this point, if you query the DBAAUDITPOLICIES view, you will find the new policy listed.SELECT POLICYNAME FROM DBAAUDITPOLICIES.CHKHREMPLOYEES.Afterwards, any of the following SQL statements log an audit event record.SELECT COUNT FROM HR.EMPLOYEES WHERE COMMISSIONPCT 2.AND SALARY 4.SELECT SALARY FROM HR.EMPLOYEES WHERE DEPARTMENTID 5.DELETE FROM HR.EMPLOYEES WHERE SALARY 1.Auditing Specific Columns and Rows.You can fine tune the audit behavior by targeting a specific column, referred to as a relevant column, to be audited if a condition is met.To accomplish this, you use the auditcolumn parameter to specify one or more sensitive columns.In addition, you can audit data in specific rows by using the auditcondition parameter to define a Boolean condition.Example 9 2.Department 5.DEPARTMENTID 5.
