Before configuring Golden Gate at DB level:

1). Put database in archivelog mode --> Requires bounce till 11gR2, but not from 12c(Need to check).

2). Enable Supplemental Logging

SELECT SUPPLEMENTAL_DATA_LOG_MIN FROM V$DATABASE;

ALTER DATABASE ADD SUPPLEMENTAL LOG DATA;

Table 5-11 Predefined Parameters of Namespace USERENV

Parameter	Return Value
ACTION	Identifies the position in the module (application name) and is set through the DBMS_APPLICATION_INFO package or OCI.
AUDITED_CURSORID	Returns the cursor ID of the SQL that triggered the audit. This parameter is not valid in a fine-grained auditing environment. If you specify it in such an environment, then Oracle Database always returns NULL.
AUTHENTICATED_IDENTITY	Returns the identity used in authentication. In the list that follows, the type of user is followed by the value returned: Kerberos-authenticated enterprise user: kerberos principal name Kerberos-authenticated external user : kerberos principal name; same as the schema name SSL-authenticated enterprise user: the DN in the user's PKI certificate SSL-authenticated external user: the DN in the user's PKI certificate Password-authenticated enterprise user: nickname; same as the login name Password-authenticated database user: the database username; same as the schema name OS-authenticated external user: the external operating system user name Radius-authenticated external user: the schema name Proxy with DN : Oracle Internet Directory DN of the client Proxy with certificate: certificate DN of the client Proxy with username: database user name if client is a local database user; nickname if client is an enterprise user. SYSDBA/SYSOPER using Password File: login name SYSDBA/SYSOPER using OS authentication: operating system user name
AUTHENTICATION_DATA	Data being used to authenticate the login user. For X.503 certificate authenticated sessions, this field returns the context of the certificate in HEX2 format. Note: You can change the return value of the AUTHENTICATION_DATA attribute using the length parameter of the syntax. Values of up to 4000 are accepted. This is the only attribute of USERENV for which Oracle Database implements such a change.
AUTHENTICATION_METHOD	Returns the method of authentication. In the list that follows, the type of user is followed by the method returned: Password-authenticated enterprise user, local database user, or SYSDBA/SYSOPER using Password File; proxy with username using password: PASSWORD Kerberos-authenticated enterprise or external user: KERBEROS SSL-authenticated enterprise or external user: SSL Radius-authenticated external user: RADIUS OS-authenticated external user or SYSDBA/SYSOPER: OS Proxy with certificate, DN, or username without using password: NONE Background process (job queue slave process): JOB Parallel Query Slave process: PQ_SLAVE You can use IDENTIFICATION_TYPE to distinguish between external and enterprise users when the authentication method is Password, Kerberos, or SSL.
BG_JOB_ID	Job ID of the current session if it was established by an Oracle Database background process. Null if the session was not established by a background process.
CLIENT_IDENTIFIER	Returns an identifier that is set by the application through the DBMS_SESSION.SET_IDENTIFIER procedure, the OCI attribute OCI_ATTR_CLIENT_IDENTIFIER, or Oracle Dynamic Monitoring Service (DMS). This attribute is used by various database components to identify lightweight application users who authenticate as the same database user.
CLIENT_INFO	Returns up to 64 bytes of user session information that can be stored by an application using the DBMS_APPLICATION_INFO package.
CURRENT_BIND	The bind variables for fine-grained auditing. You can specify this attribute only inside the event handler for the fine-grained auditing feature.
CURRENT_EDITION_ID	The identifier of the current edition.
CURRENT_EDITION_NAME	The name of the current edition.
CURRENT_SCHEMA	The name of the currently active default schema. This value may change during the duration of a session through use of an ALTER SESSION SET CURRENT_SCHEMA statement. This may also change during the duration of a session to reflect the owner of any active definer's rights object. When used directly in the body of a view definition, this returns the default schema used when executing the cursor that is using the view; it does not respect views used in the cursor as being definer's rights. Note: Oracle recommends against issuing the SQL statement ALTER SESSION SET CURRENT_SCHEMA from within all types of stored PL/SQL units except logon triggers.
CURRENT_SCHEMAID	Identifier of the currently active default schema.
CURRENT_SQL CURRENT_SQLn	CURRENT_SQL returns the first 4K bytes of the current SQL that triggered the fine-grained auditing event. The CURRENT_SQLn attributes return subsequent 4K-byte increments, where n can be an integer from 1 to 7, inclusive. CURRENT_SQL1 returns bytes 4K to 8K; CURRENT_SQL2 returns bytes 8K to 12K, and so forth. You can specify these attributes only inside the event handler for the fine-grained auditing feature.
CURRENT_SQL_LENGTH	The length of the current SQL statement that triggers fine-grained audit or row-level security (RLS) policy functions or event handlers. You can specify this attribute only inside the event handler for the fine-grained auditing feature.
CURRENT_USER	The name of the database user whose privileges are currently active. This may change during the duration of a session to reflect the owner of any active definer's rights object. When no definer's rights object is active, CURRENT_USER returns the same value as SESSION_USER. When used directly in the body of a view definition, this returns the user that is executing the cursor that is using the view; it does not respect views used in the cursor as being definer's rights.
CURRENT_USERID	The identifier of the database user whose privileges are currently active.
DATABASE_ROLE	The database role using the SYS_CONTEXT function with the USERENV namespace. The role is one of the following: PRIMARY, PHYSICAL STANDBY, LOGICAL STANDBY, SNAPSHOT STANDBY.
DB_DOMAIN	Domain of the database as specified in the DB_DOMAIN initialization parameter.
DB_NAME	Name of the database as specified in the DB_NAME initialization parameter.
DB_UNIQUE_NAME	Name of the database as specified in the DB_UNIQUE_NAME initialization parameter.
DBLINK_INFO	Returns the source of a database link session. Specifically, it returns a string of the form: SOURCE_GLOBAL_NAME=dblink_src_global_name, DBLINK_NAME=dblink_name, SOURCE_AUDIT_SESSIONID=dblink_src_audit_sessionid where: dblink_src_global_name is the unique global name of the source database dblink_name is the name of the database link on the source database dblink_src_audit_sessionid is the audit session ID of the session on the source database that initiated the connection to the remote database using dblink_name
ENTRYID	The current audit entry number. The audit entryid sequence is shared between fine-grained audit records and regular audit records. You cannot use this attribute in distributed SQL statements. The correct auditing entry identifier can be seen only through an audit handler for standard or fine-grained audit.
ENTERPRISE_IDENTITY	Returns the user's enterprise-wide identity: For enterprise users: the Oracle Internet Directory DN. For external users: the external identity (Kerberos principal name, Radius schema names, OS user name, Certificate DN). For local users and SYSDBA/SYSOPER logins: NULL. The value of the attribute differs by proxy method: For a proxy with DN: the Oracle Internet Directory DN of the client For a proxy with certificate: the certificate DN of the client for external users; the Oracle Internet Directory DN for global users For a proxy with username: the Oracle Internet Directory DN if the client is an enterprise users; NULL if the client is a local database user.
FG_JOB_ID	Job ID of the current session if it was established by a client foreground process. Null if the session was not established by a foreground process.
GLOBAL_CONTEXT_MEMORY	Returns the number being used in the System Global Area by the globally accessed context.
GLOBAL_UID	Returns the global user ID from Oracle Internet Directory for Enterprise User Security (EUS) logins; returns null for all other logins.
HOST	Name of the host machine from which the client has connected.
IDENTIFICATION_TYPE	Returns the way the user's schema was created in the database. Specifically, it reflects the IDENTIFIED clause in the CREATE/ALTER USER syntax. In the list that follows, the syntax used during schema creation is followed by the identification type returned: IDENTIFIED BY password: LOCAL IDENTIFIED EXTERNALLY: EXTERNAL IDENTIFIED GLOBALLY: GLOBAL SHARED IDENTIFIED GLOBALLY AS DN: GLOBAL PRIVATE
INSTANCE	The instance identification number of the current instance.
INSTANCE_NAME	The name of the instance.
IP_ADDRESS	IP address of the machine from which the client is connected. If the client and server are on the same machine and the connection uses IPv6 addressing, then ::1 is returned.
ISDBA	Returns TRUE if the user has been authenticated as having DBA privileges either through the operating system or through a password file.
LANG	The abbreviated name for the language, a shorter form than the existing 'LANGUAGE' parameter.
LANGUAGE	The language and territory currently used by your session, along with the database character set, in this form: language_territory.characterset
MODULE	The application name (module) set through the DBMS_APPLICATION_INFO package or OCI.
NETWORK_PROTOCOL	Network protocol being used for communication, as specified in the 'PROTOCOL=protocol' portion of the connect string.
NLS_CALENDAR	The current calendar of the current session.
NLS_CURRENCY	The currency of the current session.
NLS_DATE_FORMAT	The date format for the session.
NLS_DATE_LANGUAGE	The language used for expressing dates.
NLS_SORT	BINARY or the linguistic sort basis.
NLS_TERRITORY	The territory of the current session.
OS_USER	Operating system user name of the client process that initiated the database session.
POLICY_INVOKER	The invoker of row-level security (RLS) policy functions.
PROXY_ENTERPRISE_IDENTITY	Returns the Oracle Internet Directory DN when the proxy user is an enterprise user.
PROXY_USER	Name of the database user who opened the current session on behalf of SESSION_USER.
PROXY_USERID	Identifier of the database user who opened the current session on behalf of SESSION_USER.
SERVER_HOST	The host name of the machine on which the instance is running.
SERVICE_NAME	The name of the service to which a given session is connected.
SESSION_EDITION_ID	The identifier of the session edition.
SESSION_EDITION_NAME	The name of the session edition.
SESSION_USER	The name of the database user at logon. For enterprise users, returns the schema. For other users, returns the database user name. This value remains the same throughout the duration of the session.
SESSION_USERID	The identifier of the database user at logon.
SESSIONID	The auditing session identifier. You cannot use this attribute in distributed SQL statements.
SID	The session ID.
STATEMENTID	The auditing statement identifier. STATEMENTID represents the number of SQL statements audited in a given session. You cannot use this attribute in distributed SQL statements. The correct auditing statement identifier can be seen only through an audit handler for standard or fine-grained audit.
TERMINAL	The operating system identifier for the client of the current session. In distributed SQL statements, this attribute returns the identifier for your local session. In a distributed environment, this is supported only for remote SELECT statements, not for remote INSERT, UPDATE, or DELETE operations. (The return length of this parameter may vary by operating system.)

Table 5-12 lists the parameters of namespace USERENV that have been deprecated. Do not specify any of these parameters. Instead use the alternatives suggested in the Comments column.

Table 5-12 Deprecated Parameters of Namespace USERENV

Parameter	Comments
AUTHENTICATION_TYPE	This parameter returned a value indicating how the user was authenticated. The same information is now available from the new AUTHENTICATION_METHOD parameter combined with IDENTIFICATION_TYPE.
EXTERNAL_NAME	This parameter returned the external name of the user. More complete information can now be obtained from the AUTHENTICATED_IDENTITY and ENTERPRISE_IDENTITY parameter.

Permitting a user on UNIX / Linux to use sqlplus

http://databaseoracle.blogspot.co.uk/2006/11/permitting-user-on-unix-linux-to-use.html

1. For any normal user (not a part of "oinstall" / "dba" groups ) to be able to run sqlplus and access an ORACLE database , read/execute permissions are required for these 4 directories :
   1. $ORACLE_HOME/bin
   2. $ORACLE_HOME/lib
   3. $ORACLE_HOME/oracore
   4. $ORACLE_HOME/sqlplus
2. In addition, these 4 parameters should also be set in the user's environment (.profile) :
   1. ORACLE_HOME,
      
   2. LD_LIBRARY_PATH,
      
   3. ORACLE_SID,
      
   4. PATH

Node Eviction in 11g R2 RAC

An excellent link explaining on Node eviction.

Adding a new disk to Linux in VMWARE

Please follow the steps in below link:

http://www.matttopper.com/2006/05/adding-a-new-disk-to-a-vmware-virtual-machine-in-linux/

for any issues during mounting like:

fsck.ext3: Unable to resolve 'LABEL=/boot'
fsck.ext3: Unable to resolve 'LABEL=/home'

*** An error occurred during the file system check.
*** Dropping you to a shell; the system will reboot
*** when you leave the shell.
Give root password for maintenance

From maintainence, 

A few useful commands here; just in brief, enough as keywords for you to go googling for details, or check the man pages.

fdisk -l	(to find out the partitions on the disks)
e2label/dev/sda1	(find out or write the label for a partition. in this case, partition 1 of /dev/sda. of course, IDE disks will show as /dev/hda etc)
mount -o remount,rw /	(remount a readonly filesystem readwrite so changes can be made, especially to files like /etc/shadow, /etc/fstab, /boot/grub/menu.lst etc)
passwd	(change the root password if you have forgotten)

Sometimes it is useful to go into single user mode, especially if the server hangs when it tries to bring up the network. To do so, when grub comes up, press the up or down arrow keys, select one of the kernel, press 'e' for edit, and append "single" to the end of the line. come out of the editing by pressing enter, and press 'b' for boot. Also useful when you have SCSI RAID drivers, other than provided on the installation disk, on the server. So you really want the server to boot up with the drivers.

Usually, if you have access to the console, it is easy to boot up using CD. example, the server cd of centos. key in linux rescue at the prompt, and you will get a nice environment to use for fixing your server.

ASM Script

The ASM script of all ASM scripts !

Posted by John Hallas on February 1, 2009

The asm information script I use which gives me everything I think I need in one go.

If there are any queries that others find useful please comment on them and I will add them to the script.

Credit where credit is due. I think Alan Cooper wrote the original version, although it has been amended since then.

RMAN backup details query

RMAN QUERY TO FIND BACKUP DETAILS


RMAN VIEWS (WHEN NO RECOVERY CATALOG AVAILABLE) . i have provide the example as per 11gR2.


To Display the backup details of the database (Full, Incremental & Archive log backup), when the DB is not connect with the recover catalog. (Work in Mount stage)


SQL> select session_key,
input_type,
status,
to_char(start_time,'yyyy-mm-dd hh24:mi') start_time,
to_char(end_time,'yyyy-mm-dd hh24:mi') end_time,
output_bytes_display,
time_taken_display
from v$rman_backup_job_details
order by session_key asc;

Below query will display the backup piece that hold the backup of archive log, datafile in the DISK or TAPE Drive.

Query to see Backed Up Archive Logs in the database (Work in Mount stage)





SQL> select recid,set_stamp,sequence#,first_change#,next_change#

from v$backup_redolog;





Query against the V$BACKUP_PIECE view to find backup details of a particular archive log (Work in Mount stage)





SQL> select r.sequence#, p.handle from v$backup_piece p, v$backup_redolog r

where r.set_stamp = p.set_stamp and r.set_count = p.set_count

and r.sequence# = 63





Note: 63 is the sequence number.

Query against the V$BACKUP_PIECE view to find backup details of a particular datafiles (Work in Mount stage)





SQL> select d.file#, p.handle from v$backup_piece p, v$backup_datafile d where d.set_stamp = p.set_stamp and d.set_count = p.set_count and d.file# = 3





Note: 3 is the datafile number.









SQL> select table_name from dict where table_name like 'V$%RMAN%';

V$RMAN_BACKUP_JOB_DETAILS è displays details about backup jobs.





V$RMAN_BACKUP_SUBJOB_DETAILS è merges similar operations within an RMAN session into a single row. For example, if there are four BACKUP DATAFILE commands, three RECOVERY COPY OF DATAFILE commands, and one BACKUP RECOVERY AREA command, this view will contain three rows - one each for BACKUP, ROLLFORWARD, and COPY_DISK_TO_TAPE operation.





V$RMAN_BACKUP_TYPEè displays information about RMAN backup types.

SQL> select * from V$RMAN_BACKUP_TYPE;





WEIGHT INPUT_TYPE

6 DATAFILE FULL

7 DB INCR

8 RECVR AREA

9 DB FULL





V$RMAN_COMPRESSION_ALGORITHM è provides descriptions of supported compression algorithms. It is used by the RMAN client.





V$RMAN_CONFIGURATION è Information about RMAN persistent configuration settings.





V$RMAN_ENCRYPTION_ALGORITHMS è displays supported encryption algorithms. It is used by the RMAN client to validate user-requested algorithms. This view will list AES128, AES192, and AES256 encryption algorithms for the current release. The default algorithm is AES128.





V$RMAN_OUTPUT è displays messages reported by RMAN. This is an in-memory view and is not recorded in the controlfile. The view can hold 32768 rows.





V$RMAN_STATUS è displays the finished and on-going RMAN jobs. For on-going jobs, this view displays progress and status. The jobs which are in progress are stored only in memory while the finished jobs are stored in the controlfile
