List of instance and databases

My sql server contains multiple instances and each instance contains multiple databases.
Now how to list of all the instances and their corresponding databases?
i used select * from sys.servers for instances and sys.databases for number of databases.
But how to list of all the instances and databases using single query?

Hi
List all Instances
option 1: Pwershell
Get-Service | Where-Object {$_.Name -like 'MSSQL$*'}
Option 2: query this registry
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server.....
Option 3: go to regitry HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\Instance Names
* Here you can find other option like OLTP and not just SQL
Option 4: RUN -> services.msc
Find all services named "SQL Server". The instance name is in the brakets
Option 5: Open sql server configuration manager -> SQL Server Services
There are more options if you need :-)

Instance and database reset

Hi,
Let's say hypothetically we are encountering so many process errors and exceptions, that we would like to start over and reset the soa/bpm domain and the database associated. In this case: delete all deployments, their related files, reset the DB content to an empty post RCU state (as in empty list of processes, empty list of instances, etc.)
Is this possible? Or we do need to re-create another set of DB schemas and another soa-infra weblogic domain?
Thanks
Miguel

There are low level WebLogic server commands (wlst) with which you can undeploy composites. Clearing out instances requires an archiving type database script as this is usually an archive procedure on a production machine.
To find out more, you would look at WLS and SOA Suite administration and since SOA Suite 11gR1 has been released, you can review the documentation on OTN here:

One instance and two databases?

Hello, I've installed oracle database on my server. I've read a lot of documentation to learn the basic concepts.
Ok, I have a question. I have read that one instance only can manage ONE database. Is it true? If it's true, how on earth I can create two database? for example, I want to create database-one and database-two.
I would create these with CREATE DATABASE command. How does Instance know if I want to access to database-one or database-two. How I indicate it in initilitation parameter file of my instance?
In sumary, Can one instance works with two databases?

Look at the following output. If I do not set my ORACLE_SID variable, the 9.2.0.7 client connects to the 9.2.0.7 database instance. If I set my ORACLE_SID , the same 9.2.0.7 client now connects to the 10.2.0.1 database (the database specified in the ORACLE_SID variable).

V$instance and V$database

Hi
Are these tables can contain more than one row? in which situation?

Thinks for the help
I'm trying to figure out some things about RAC environment and SBDB.What is SBDB?
Is out of tables ($ V $ V INSTANC and DATABASSE) I can know whether the environment is a RAC environment
I would suggest to look for the parameter cluster_database in the parameter file. If this parameters comes as true , that means you are on a clustered database. Otherwise, it would be false all the time. I don't have a db with me to test the output of both the views but based on the documentation, there is no column in both which does tells you that its a rac or non-rac db.
and how NODE / DB / INSTANCE have around, same goes for SBDB environment.Sorry, I couldn't parse your statement. Can you rephrase please?

Listener (and database instance) does not starts up automatically: ORA-12514: TNS:listener does not currently know of service requested in connect descriptor

Hi at all.... I'm a newbie with database oracle.,
I have the follow problem:
I installed Oracle Database 11g R2 XE on my guest operating system CentOS 6.5.
I have changed the hostname in my SO CentOS (where is installed oracle 11g R2 XE) after installation was completed successfully.
-) Before and during installation the hostname was localhost.
-) After installation I changed the hostname in VMCentOS
From the moment I changed the hostname, nothing starts up automatically. In particular, the listener and the database instance does not starts up automatically.
When I starts up the listener manually and I try to connect to database instance with SQLPLUS i get this error:
ORA-12514: TNS:listener does not currently know of service requested in connect descriptor
I think that the problem is due to the changed hostname because I, for testing and debugging purpose, re-installed a new OS CentOS virtual machine, re-installed oracle database 11g and I have not got that problem. The database instance and the listener starts up automatically!
Can any one tell me if maybe the problem is related to the hostname changed? ... and Why?
P.S.: After changed the hostname I have also modified the listener.ora and the tnsnames.ora by modifying the HOST with the correct hostname.

-) Output of command chkconfig (there isn't any line oracle-xe 0:off   1:off 2:on 3:on 4:on 5:on 6:off):

10g ASM instance and 11g database

Hello,
does anybody ever connected ASM instance10.2 and database 11.1? Is there any sense in it? When I have two databases: 10.2 and 11.1 running on the same host, should they both use separate ASM instances or is it possible to connect them to the common one?
Thanks,
Aliq

Yes, such combination is supported with asm 10.2 and database 11.1.
You can check metalink note 337737.1 as well.

List of indexes and columns for a database.

Hi
Do you know the SQL command to get the list of indexes and associated columns for all tables for a given database ?
The following only shows me the table and index name but I would also like to get the colums for each index
SELECT o.name,       i.name FROM sysobjects o JOIN sysindexes i    ON (o.id = i.id)
Can you pls help
Thanks
H.

There isn't a single command that will do that.
There is the sp_helpindex stored procedure which will give you the information on indexes one table at a time, you could call it in a loop, but there is other information in there as well, so the output would be messy.
You can look at the source code for sp_helpindex to find out how it decodes the key column names.
use sybsystemprocs
go
sp_helptext sp_helpindex
go
The core of it is this loop, which builds up a list of the column names in @keys, a varchar(1024) declared earlier.
        ** First we'll figure out what the keys are.
        declare @i int
        declare @thiskey varchar(255)
        declare @sorder char(4)
        declare @lastindid int
        declare @indname varchar(255)
        select @keys = "", @i = 1
        set nocount on
        while @i <= 31
        begin
                select @thiskey = index_col(@objname, @indid , @i)
                if (@thiskey is NULL)
                begin
                        goto keysdone
                end
                if @i > 1
                begin
                        select @keys = @keys + ", "
                end
                /*select @keys = @keys + index_col(@objname, @indid, @i)*/
                select @keys = @keys + @thiskey
                ** Get the sort order of the column using index_colorder()
                ** This support is added for handling descending keys.
                select @sorder = index_colorder(@objname, @indid, @i)
                if (@sorder = "DESC")
                        select @keys = @keys + " " + @sorder
                ** Increment @i so it will check for the next key.
                select @i = @i + 1

Difference between Database, instance and schema

Hi
I don't know the clear difference between database, instance and schema.. In the broad sense, everything seems to be the same. If anyone can differentiate between them with some example, that will be of great help.
Thank you.

Hi,
In Oracle, people often do use "database" and "instance" interchangeably, or together as one term: "database instance".
A "schema" is quite different. A schema is a collection of objects (such as tables, indexes or procedures). Every object belongs to exactly one schema, and every schema is a part of exactly one database. (Names may not be unique, however. For example, your database may have one schema named SCOTT, and another schema named USER1. Each of those schemas may have a table named EMP. The EMP table in the SCOTT schema, or SCOTT.EMP, is not the same as the EMP table in the USER1 schema, or USER1.EMP. A different database, my database for example, may also have schemas called SCOTT and USER1, which are completely independent of the SCOTT and USER1 in your database.)

Difference between Instance Crash and Database Crash in Standalone and RAC?

I am new to Oracle Environment. I would appreiciate if i get clarified on the "_+Difference between Instance Crash and Database Crash in Standalone and
RAC_".+

Sivaprasad S wrote:

Literally, database crash means that the database itself is damaged in some way. A disk is no more. Data files are corrupted. Etc. The database itself thus causes the crash - and a database crash will also cause all database instances (RAC or single) for that database to crash too.
An instance crash will therefore mean that the crash occurs in the instance due to an Oracle bug or similar. In other words a s/w error and not a database error. The database is still "fine", but the instance not. Instance crashes. However, any other instance on that same (RAC) database will still be fine as the database itself is unaffected by that s/w error in the crashed instance.
If you mean something different, please enlighten us. Not all crashes are equal. {noformat};-){noformat}

ORA-12505: Database Instance and Agent Connection to Instance will not work

Hi,
I have the following error: in Oracle 10g I try to connect to OEM and the listener is up but the Database Instance and Agent Connection to Instance are down. When I attempt to restart the instance, OEM will just hang indefinitely. I have used tnsping and the results are OK. Is that descriptive enough? What can I do to fix this?

John

I changed the SID because I was mistaken and thought of the oracle database name. I have corrected the ORACLE_SID to that given in my tnsnames.ora file which I post here:
ORACLE =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = Lasirius-laptop)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = oracle)
EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
(CONNECT_DATA =
(SID = PLSExtProc)
(PRESENTATION = RO)
These are the default settings that were made on installation. I have been working with this installation for 2 months, and it just suddenly stopped working. I have changed no other settings apart from the mistaken ORACLE_SID environment variable in this post, which has now been changed to PLSExtProc. Here is my init.ora:
# replace "clustdb" with your database name
db_name = clustdb
compatible=9.0.0
db_files = 1024 # INITIAL
#INITIAL
#db_files=80
#SMALL
#DB_files=400
#MEDIUM
#db_files=1000

ASM and database instance sharing same home. Can i split them?

Hi I am running on 10.2.0.1.0 in a 2 server RAC cluster on linux. ASM and db instance are sharing the same home.
I now need to upgrade my ASM instance and clusterware to 11g, but just want to keep my db at 10g because of some compatability issues ( i will probably still need to upgrade the db to 10.2.0.5.0).
Is there any way i can split my Oracle Home so that i now can upgrade my ASM home and keep my prod DB instance still at 10g?
Thanks again. John

Hi,
Is there any way i can split my Oracle Home so that i now can upgrade my ASM home and keep my prod DB instance still at 10g?Yes... no problem.
See this notes on MOS:
10g to 11g R1
*How To Upgrade ASM from 10.2 to 11.1 (RAC)? [ID 736127.1]*
or to 11g R2
*ASM 11gR2: How To Upgrade An ASM Instance To Release 11gR2 (11.2.0.1.0)? [ID 950200.1]*
