• Oracle sid and database name

  Hi guys,.
  
  I'm a bit confused by the name ORACLE_SID and database. I understand that an instance may be attached to a database, and that a database can be attached to multiple instances.
  
  Essentially, when we set the values in our init.ora, we set the values of the instance, or the database, or is it a mixture? that is the instance and the database to which it can connect?
  
  Also, the DB_NAME parameter that specifies what database, the instance can connect to?
  
  And why does it say in the [Oracle documentation | http://download.oracle.com/docs/cd/B10501_01/server.920/a96521/create.htm#1003921] which the DB_NAME initialization parameter value must match the SID setting. I thought that they should not be the same?
  
  Thank you

  1. a DATABASE is the physics of files - data files for tablespaces (SYSTEM, UNDO, TEMP, USERDATA, USERINDEXES etc.), controlfile (s), redolog files and possibly the archivedlog files.

  2. an INSTANCE is the set of processes that access the database. So, when you start an Instance, you start background processes that allow users to access the files of database.

  3. a DATABASE can have multiple INSTANCES in a configuration of OPS/PAP. Thus, each Instance is configured with a different name - the ORACLE_SID maps the processes of the Instance, the Instance name is the name for the process. (1 single database accesses an Instance)

  4. a listener allows connections when not coming not from the same ORACLE_HOME. The listener starts for a database Instance (via the inputs the listener.ora) or the database records with the listener running (when PMON updates the default listener or "local_listener").

  5. users (ApplicationServers etc.) connect to the INSTANCE, not in the database. Users access the Instance of the SID mapping directly or via a listener. If you have access to via a listener, they specify a SID or a SERVICE_NAME in their connection settings.

  I understand that an instance may be attached to a database, and that a database can be attached to multiple instances.

  Can access an Instance (I would use 'access' rather than 'attach') 1 single database. However, a database available under multiple instances. (In any case, a database is not attach to an instance - this is the mechanism that opens the database files - access).

  When we set the values in our init.ora, we set the values of the instance, or the database, or is it a mixture?

  We put them to the Instance. (It's the ControlFile who really knows the database!

  what the DB_NAME parameter that specifies what database, the instance can connect to?

  If the 'db_name' specified in the init.ora does not match the database name, you get an error and can not access the database.

  Why do we say in the Oracle documentation...

  It is a recommendation and is not mandatory.

  Think about what happens when you CLONE a database. You can CLONE a database to a different instance name, and then change the DB_NAME after a successful RECOVERY and RESETLOGS OPEN (for example that dbca is when it creates a database of preconfigured for you: he one of the clones and then renames the database).
  So, I can clone of database 'PROD_A' ("PROD_A' ORACLE_SID) and ORACLE_SID"TEST_A"during the RESTORE process and to RECOVER the DB_NAME to"TEST_A"remains"PROD_A"until I have recreate the ControlFiles and rename the database"TEST_A ".

  (And we don't start talking about GLOBAL_NAME and SERVICE names-find you on them to confuse you more!)

• The AUDIT command in, oracle apex (version 4.2.5.00.08), error "ORA-00911: invalid character '.

  I am trying to run

  "AUDIT INSERT, UPDATE, DELETE on emp BY ACCESS WHENEVER SUCCESSFUL;"

  in "SQL commands" on oracle-apex (version 4.2.5.00.08).

  I get the error message ' ORA-00911: invalid character '.

  Can someone tell me the solution for this?

  Apex environment we need to set the database AUDIT_TRAIL to TRUE for the control

  "AUDIT INSERT, UPDATE, DELETE on emp BY ACCESS WHENEVER SUCCESSFUL;"  to work.

  By their Summit, to be able to change the setting of database AUDIT_TRAIL we have to log-in as a DBA from the link "SQL workshop--> utilities--> on the database.

• vCenter Database Name

  Dear all,

  I intend to implement a number of databases of vcenter in different data centers - all have the same standard name, say 'VCDATA '.

  Subsequently, the plan is to use modes related to connect to vcenter instances - is there any problem with the same database name when you use bound mode?

  Thank you

  I didn't have the need to use additional related yet myself, but as far I understand modes related, there is no need to use again the same PB (for example, MSSQL, Oracle,...) for the different vCenter servers that you want to link. When you configure related modes vCenter replicates only the data necessary to access the services (information connection, certificates), information on licenses, user roles using Microsoft ADAM. The different vCenter servers go directly to other databases. With the vSphere Client you only access the vCenter vCenter servers Service.

• I use a database program in a number of previous versions of windows and windows 7 does not allow the program to launch denial of service.

  Application of program compatibility does not start

  I use a database program in a number of previous versions of windows and windows 7 does not allow the program to launch denial of service.  What gives?

  If you have Windows 7 64 bit without BACK program can run because there is no 16-bit subsystem to run it.

  Try dosbox http://www.dosbox.com/. If that won't work your program, you'll need either a new database or run the BACK or on a 32-bit version of Windows in a virtual machine like VirtualBox https://www.virtualbox.org/.

• HOWTO: install Oracle database software in a new oracle home

  Hallo,

  I approach my first upgrade of database Oracle 11.2.0.1 to 11.2.0.4 I want to perform a manual upgrade.

  The first step (after download and extract the files from the zip in a folder) is "to install the software in a new oracle home.

  I think that the setup.exe to launch is that of folder/database/setup.exe

  the installer give me 3 choices:

  -create and configure a new database

  -install database software only

  -to upgrade an existing database

  To create the oracle new house I just set the path to install in a different folder, is it not?

  I thank the of FYI

  In a first time install 11.2.0.4 in a new folder

  Choose the option "Install database only software" for the manual upgrade
