Some important V$ views

I cannot stop myself to share a few great views which provide excellent information

V$SGA :
We can get information about the system global area (SGA)

V$SGA_DYNAMIC_COMPONENTS:
Can get information about the dynamic SGA components. This summy provides details based on all completed SGA resize operations since instance startup. All sizes are expressed in bytes.

V$SGAINFO:

Can get information about the SGA, including the sizes of different SGA components, the granule size, and free memory.

V$SGASTAT

We can get detailed information on the system global area (SGA).

V$SHARED_SERVER

We can get information on the shared server processes.

V$TABLESPACE

Can get tablespace information from the control file

V$TRANSACTION

Can get lists the active transactions in the system.

V$TRANSACTION_ENQUEUE
displays locks owned by transaction state objects.

V$VERSION

We can get version numbers of core library components in the Oracle Database.


V$LOGFILE

This view contains information about redo log files.

V$BACKUP_DATAFILE_DETAILS:
We can get information about restorable datafiles. It will include all datafiles backed in the backup set, image copies, and proxy copies.

Oracle basic terms and concepts

Instance:
Oracle database is associated with an Oracle instance. While database getting started on serve, Oracle allocates a memory area called the System Global Area (SGA) and starts one or more Oracle process (depends on configuration)

The combination of the SGA and the Oracle process is called an Oracle instance.

SGA= Context areas, Database Buffer Cache and Redo log and Oracle processes

States of instances
1.Mount
2.Opened
3.Unmount

Parameter file
To start any Oracle instance, Oracle must read an initilization parameter file: A file

containing configuration parameters for that intance and databse.
Initialisation parameter categorrized into different groups

Parameter related to Name
Parameter for limit setting maximum and minimum
Parameter for capacity : SGA (variable)

Parameter file tells Oracle :
The name of the database for which to start up an instance
How much memory to use for memory structures in the SGA
What to do with filled online redo log files
The names and locations of the database control files
The names of undo tablespaces or private rollback segments in the database

How to change Parameter values:
--------------------------------
Variable parameters for example related to SGA can be changed by dynamically by using ALTER SESSION or ALTER SYSTEM

Note:
If we are not using server parameter file, change made using the ALTER SYSTEM statement are only in effect for the current instance, it means if we reboot server, changes will be revert back to previous values. We must manually update the text initialization parameter file

These are daily useable commands in SQL Commands (Oracle)

1.How to check Log Mode:
SELECT LOG_MODE FROM V$DATABASE;

2.Change Log Mode:

Alter database archivelog; (Database must be in mounted mode, database Alter command will not permanently add entries in spfile, we need to do it manually)

to open database in mount only mode startup mount

3.Open database read only

ALTER DATABASE OPEN READ ONLY;

4. Open Database in read and write mode:

ALTER DATABASE OPEN READ WRITE;
However, read-write is the default mode.

5.Start commands

1.Normal start = startup
2.Startup mount


Other various commands

V$ARCHIVED_LOG

Displays historical archived log information from the control file.

V$ARCHIVE_DEST

Describes archive destinations, and the current value, mode, and status of these destinations.

V$ARCHIVE_PROCESSES

Displays information about the state of the various archive processes for an instance.

V$BACKUP_REDOLOG

Contains information about any backups of archived logs. If you use a recovery catalog, the RC_BACKUP_REDOLOG contains similar information.

V$LOG

Displays all redo log groups for the database and indicates which need to be archived.

V$LOG_HISTORY

Contains log history information such as which logs have been archived and the SCN range for each archived log.

SQL commands to know database and instance name

SQL> Select name from v$database;
SQL> select instance_name from v$instance;
SQL> select * from global_name;
SQL> SELECT VALUE FROM V$PARAMETER WHERE NAME='db_name';
SQL> select global_name from global_name

Tmadmin commands to monitor and configure dynamically

Tmadmin has almost 50 commands, and broadly can be categorized into 7

1.Universal Device List and transaction log
2.Start, shutdown and modify part or all of the configuration
3.Monitor the configuration and its performance
4.Global Transactions
5.Services
6.Servers and its Groups
7.Use other commands


TMAdmin is a command interpreter that provides monitor and modification of the bulletin board.The command requires the

TUXCONFIG environmental variable to set

We can administrator only ne tmadmin process at a time.There are two commandline options aviable

-r (readyonly)
-c(configuration mode)
-v tmadmin to display TUXEDO version number and license number



TMAdmin miscellanmous commands

defualt (d) set default values for arguments of other commands
dump(du) dump current bulletin board into a file
ech(e) echo input command lines
help (h) print command list or command syntax
pageinate(page) pipe output of commands to a pager
quite(q) terminte the session
verbose(v) show output in verbose mode
!! repeat previous shell command
Repeat last tmadmin command

Default (d)

The default command of tmadmin allows to default values to be set for serveral frequentlyu used parameters.
