For slow Replicat’s, latency may be due to missing indexes on target. 5. Replicat having to process Update, delete of rows in very large tables. ... OGG provides a parameter called ‘FORMAT RELEASE’ which allows customers to use different versions of Oracle GoldenGate Extract, trail files , and Replicat together.

After installing and starting up your oracle 12c database, check that the "Unified Auditing" status by default it should be "FALSE". When you create a new database, by default the database uses mixed mode auditing, which enables both traditional (that is, the audit facility from releases earlier than Release 12c) and the new audit facilities (unified auditing). AUDITING :- Oracle stores information that is relevant to auditing in its data dictionary. Every time a user attempts anything in the database where audit is enabled the Oracle kernel checks to see if an audit record should be created or updated . Audit data can be stored in a database (SYS.AUD$) table or in an OS file residing in AUDIT_FILE_DEST.

Oracle auditing of sensitive data can be accomplished with Oracle Fine Grained Auditing . Oracle FGA provides the capability to generate rich audit trail for specific objects or columns in the database. Oracle FGA is an important tool when hardening your database platform, enabling you to see exactly how your sensitive data is being accessed. If you are observing fast growth in SYSAUX tablespace and your database version is 12c, then you need to check for the sysaux occupants to find the root cause. In case if you find the top occupant name as AUDIT_TABLES , there could be some purging issue with audit table. In this blog, will see how to check and purge database trail records from audit table in manual and automate methods. If you enable the unified audit feature announced with 12c, all audit records will be in the UNIFIED_AUDIT_TRAIL table. Logon failure records will not be in this table because the corresponding policy is not enabled by default. The policy ORA_LOGON_FAILURES must be enabled to audit the Failed Logon attempts.

According Oracle 12c documentation, you can see what UA is about. The unified audit trail, which resides in a read-only table in the AUDSYS schema in the SYSAUX tablespace, makes this information available in a uniform format in the UNIFIED_AUDIT_TRAIL data dictionary view.We see more points in the same document.

The ODBC driver has Oracle's standard client-server version interoperability, see Support Doc ID 207303 At the University, installing the Oracle client and ODBC driver is basically a four or five step process: 1 Once you have created a connection to an Oracle database, you can select data from the available tables and then load that data into.

4. if you need to set or change the auditing destination but if not, you can pass this step.

Connected to: Oracle Database 12c Enterprise Edition Release 12.1.0.2.0 - 64bit Production With the Partitioning, OLAP, Advanced Analytics, Real Application Testing and Unified Auditing options SQL> alter session set nls_date_format='yyyy.mm.dd'; Session altered. SQL> quit.

Yes. Significant changes happen to Unified Auditing in Oracle Database 12.2.0.1. Mostly internally as the mechanism used to dump the audit records in Oracle 12.1.0.x when Unified Auditing was on turned out to be very good for write performance, but not so good when you tried to read data. See my blog post from a few weeks ago how to deal with.

Oracle auditing setup & configuration. The Oracle audit command is used to to create specific audit trails for Oracle tables. to enable Oracle auditing you must set the initialization parameter "audit_trail = true" and run the cataudit.sql scripts (as SYS). Also see ORA-01400: cannot insert NULL into ("SYS"."AUDIT_DDL"."DICT_OBJ_TYPE") tips.

Check the status of audit is Enable or Disable. SQL> show parameter audit_trail. Brief of following parameter values: NONE- Auditing is disabled. DB- Auditing is enabled, (all audit records stored in table (SYS.AUD$). DB,EXTENDED- As DB,but the SQL_BIND and SQL_TEXT columns are also populated for SYS.AUD$ table.
