How To Find the EBS XML Publisher Temporary Directory Via SQL? (Doc ID 1189723.1)

Direct NFS: please check that oradism is setuid

Issue:

Getting the following message in alert log and instance not starting:

Direct NFS: please check that oradism is setuid

To correct, the following permissions are needed on:

ls -la $ORACLE_HOME/bin/oradism

-rwsr-x— 1 root oinstall 72416 Aug 12 2015 /u01/app/oracle/product/11.1.0.1/db/bin/oradism

Fix:

If required, shutdown DB and change permission as follows:

sudo su

cd /u01/app/oracle/product/11.1/db/bin

chmod 750 oradism

chmod u+s oradism

Restart instance

or
run $ORACLE_HOM/root.sh

Useful SQL

– View servers accessed using Direct NFS

select * from v$dnfs_servers;

– View files currently open using Direct NFS

select * from v$dnfs_files;

– View open network paths or channels to servers for which Direct NFS is providing files

select * from v$dnfs_channels;

– View performance statistics for Direct NFS

select * from v$dnfs_stats;

To Enable DFNS:

===========

Shutdown DB

On all hosts:

cd $ORACLE_HOME/lib

mv libodm11.so libodm11.so_bak

ln –s libnfsodm11.so libodm11.so

Lets create defaults file to make adpatch a little non-interactive:

==============================================

Put addefaults.txt at a safe place and make sure it is not overwritten or deleted.

adpatch defaultsfile=/home/applmgr/SHAIK1/addefaults.env

When the adpatch asks for patch directory location then terminate the autopatch session using ctrl +c

Verify the addefaults.env is created

To use the defaults file while applying the patches just pass the above file that we created ...

adpatch defaultsfile=/home/applmgr/SHAIK1/addefaults.env logfile=XXXXX.log patchtop=/u01/stage/patches/XXXXX driver=uabc.drv interactive=no

adpatch should automatically pick up APP_TOP, ORACLE_HOME, system password and apps password from defaults file.

Fine Grain Auditing(FGA):

Now you can audit SELECT, INSERT, UPDATE, and DELETE statements under one policy using Fine Grain Auditing package(dbms_fga.add_policy).

To manage a fine-grained audit policy, you use the DBMS_FGA PL/SQL package. This package enables you to add all combinations of SELECT, INSERT, UPDATE, and DELETE statements to one policy. Only one record is generated for each policy for successful MERGE operations.

The audit policy is confined/limited 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. In addition, no matter how a user connects to the database—from an application, a Web interface, or through SQL*Plus or Oracle SQL Developer—Oracle 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.

Note: If you audit tables that have sensitive data, remember that DB+EXTENDED and XML+EXTENDED settings for the DBMS_FGA.ADD_POLICY audit_trail parameter will capture this data.

Use of audit_condition

You can define a condition under this variable for example...If anyone tries to access the salary and commission_pct columns.

Then the condition would be:

audit_condition => 'DEPARTMENT_ID = 50', audit_column => 'SALARY,COMMISSION_PCT,'

Create new policy:

SQL> show user

USER is "SEC"

SQL>

SQL> exec dbms_fga.add_policy(object_schema=>'HR',object_name=>'EMPLOYEES',policy_name=>'AUDIT_EMPS_SALARY',audit_condition=>null,audit_column=>'SALARY',enable=>FALSE);

PL/SQL procedure successfully completed.

Check the status of the new policy:

SQL> show user

USER is "SYS"

SQL> @sql.sql

SQL> select object_name,policy_owner,policy_name,enabled from dba_audit_policies;

OBJECT_NAME POLICY_OWNER POLICY_NAME ENA

------------------------------ ------------------------------ ------------------------------ ---

Enable Policy:

SQL> exec dbms_fga.enable_policy(object_schema=>'HR',object_name=>'EMPLOYEES',policy_name=>'AUDIT_EMPS_SALARY');

PL/SQL procedure successfully completed.

Verify whether the policy is enabled or not:

SQL> show user

USER is "SYS"

SQL> select object_name,policy_owner,policy_name,enabled from dba_audit_policies;

OBJECT_NAME POLICY_OWNER POLICY_NAME ENA

------------------------------ ------------------------------ ------------------------------ ---

How to Encrypt OracleTablespace

Set the Tablespace Master Encryption Key before you can encrypt or decrypt the tablespaces, you must generate or set a master encryption key.

The tablespace master encryption key is stored in an external security module and is used to encrypt the TDE tablespace encryption keys. Check to ensure that the ENCRYPTION_WALLET_LOCATION (or WALLET_LOCATION) parameter in the sqlnet.ora file points to the correct software wallet location.

ENCRYPTION_WALLET_LOCATION= (SOURCE=(METHOD=FILE)(METHOD_DATA= (DIRECTORY=/app/wallet)))

Unified Master Encryption Key or the master encryption key for transparent tablespace encryption and transparent column encryption are now combined to one unified master encryption key. Combining these keys enables transparent re-key operations for both of these transparent data encryption features, regardless of whether the master encryption key is stored in the Oracle Wallet or in one of the certified Hardware Security Modules offered by RSA, SafeNet, Thales (including nCipher), and Utimaco.

Create the directory for the wallet:

[oracle@collabn1 ~]$ mkdir -p /u01/app/oracle/admin/wallet

Add the wallet details in the sqlnet.ora file:

[oracle@collabn1 ~]$ vi $TNS_ADMIN/sqlnet.ora

ENCRYPTION_WALLET_LOCATION= (SOURCE=(METHOD=FILE)(METHOD_DATA= (DIRECTORY=/u01/app/oracle/admin/wallet)))

Verify the sqlnet.ora

[oracle@collabn1 ~]$ cat /u01/app/oracle/product/11.2.0.2/SHAIKPROD/network/admin/sqlnet.ora

ENCRYPTION_WALLET_LOCATION= (SOURCE=(METHOD=FILE)(METHOD_DATA= (DIRECTORY=/u01/app/oracle/admin/wallet)))

Create the master encryption key & wallet:

NAME OPEN_MODE

--------- --------------------

ORCL READ WRITE

When you create the master encryption key using the ALTER SYSTEM SET ENCRYPTION KEY IDENTIFIED BY "password" command, TDE checks to see if a wallet exists in the default or specified location. If no wallet exists, then a wallet is created automatically.

SQL> alter system set encryption key identified by "secretpass";

System altered.

Verify the wallet file is created:

SQL> !ls /u01/app/oracle/admin/wallet

ewallet.p12

Create the tablespace with the encryption:

Here: algorithm can have one of the following values:

■ 3DES168

■ AES128

■ AES192

■ AES256

SQL> create tablespace securetbs datafile '+DATA2' size 10m autoextend on next 1m

encryption using 'AES256'

default storage(encrypt);

Tablespace created.

Verify whether the tablespace encryption is enabled or not:

SQL> select tablespace_name,status,encrypted from dba_tablespaces;

UNDOTBS1 ONLINE NO

9 rows selected.

How to open/close the wallet:

SQL> alter system set encryption wallet close identified by "secretpass";

System altered.

SQL> alter system set encryption wallet open identified by "secretpass";

System altered.

Enable oracle Wallet auto_login:

You can create an auto login wallet with Oracle Wallet Manager or the orapki command-line utility. The auto login wallet allows convenient access to encrypted data across database instance restarts.

[oracle@collabn1 ~]$ which orapki

/u01/app/oracle/product/11.2.0.2/SHAIKPROD/bin/orapki

[oracle@collabn1 ~]$ orapki wallet create -wallet /u01/app/oracle/admin/wallet/ewallet.p12 -auto_login

Oracle PKI Tool : Version 11.2.0.1.0 - Production

Enter wallet password:

[oracle@collabn1 ~]$ ls -lrt /u01/app/oracle/admin/wallet/

total 8

-rw-r--r-- 1 oracle dba 1573 Aug 14 02:21 ewallet.p12

-rw------- 1 oracle oinstall 1651 Aug 14 03:01 cwallet.sso

After the auto_login you don’t have to worry about opening and closing the wallet manually.

Total Recall or Flashback data archive:

A Flashback Data Archive provides the ability to track and store transactional changes to a table over its lifetime. A Flashback Data Archive is useful for compliance with record stage policies and audit reports.

Flashback data archive is stored in one or more tablespaces and can have multiple flashback data archives at the same time in the database.

Flashback data archive is configured using retention time i.e you can define the flashback data archive to live as long as you want..

SQL> show user

USER is "SYS"

SQL> create tablespace tbs1 datafile '+DATA2' size 10m autoextend on next 1m;
