An Oracle_home to several databases

Hello

It is with respect to Oracle e-Business.

Can we create an Oracle_Home to host multiple databases? I'm sure that it works for non-Ebiz environments.

But if we have an ORACLE_HOME host several databases, what are the consequences so that cloning?

Thank you

You cannot share the ORACLE_HOMEs for EBS databases - each instance requires a separate ORACLE_HOME/dedicated. What business or technical problem are you trying to solve?

You must run the script catupgrd.sql for each database individually.

Despite the remarks about oradim, you will generally need to run explicitly. Take your question at face value, the procedure is quite simple:

1. install the oracle RDBMS software

1.1 you can choose to have a database created as part of the installation, or not. If you choose to create one as well as the installation, the installer will call the utility "dbca" once installation is complete. DBCA is "Database Configuration Wizard" and utility oracle for creation, deletion and some configurations of databases. This makes things easier, but everything can be done manually by calling "oradim", then from sqlplus and issue of an appropriate CREATE DATABASE statement followed invocation of several sql scripts located in ORACLE_HOME\rdbms\admin.

2. to create a database after the software installation is complete (your first database, or an extra), just run the utility "dbca.

The dbca utility will take care of configuring the necessary Windows services.

Doubt on single server multiple vs single-server instances several databases

Hello
Here is my banner for oracle:
Oracle banner:
Oracle Database 11 g Enterprise Edition Release 11.2.0.1.0 - 64 bit Production
PL/SQL Release 11.2.0.1.0 - Production
"CORE 11.2.0.1.0 Production."
AMT for 64-bit Windows: Version 11.2.0.1.0 - Production
NLSRTL Version 11.2.0.1.0 - Production
When you use the dbca command, it creates a new database. So is it possible to have multiple databases at the same time running on the same server?
I tried this option where I had created 2 databases A and B both running.
He kept to launch ' ORA-12520: TNS:listener could not find a Manager is available for the type of requested server "intermittently. I have not found any useful document to solve this because of which I ended up recreate all objects in database B to the database A. Data Base A therefore has its own schemas and schemas from database B.
Below are examples of files tnsnames.ora and listener.ora, sqlnet.ora trying this option:

sample tnsnames.ora file.
A =.
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = abc.com) (PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = A)
)
)
B =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = abc.com) (PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = B)
)
)
Listener.ora, example:
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = abc.com) (PORT = 1521))
(ADDRESS = (PROTOCOL = CIP)(KEY = EXTPROC1521))
)
)
ADR_BASE_LISTENER = C:\OracleDatabase
SQL Net.ora:
NAMES. DIRECTORY_PATH = (TNSNAMES, EZCONNECT)
ADR_BASE = C:\OracleDatabase
Lsnrctl status showed services for each database.
All the world is facing this problem? Can we have multiple databases on a server with a listener running on the same computer? So my Tnsnames.ora file would have 2 strings of connections and file listener with an entry of the listener.
Can you please share your tnsnames.ora and listener.ora files?
Also, how to create a single database with multiple instances on the same server? Please tell me about the document that contains an example of this.

Yes, you can have several databases (running different ORACLE_SIDs) the ORACLE_HOME even on a single server.

I suspect that the ORA-12520 error was the result of certain constraints of resources (cpu, memory or i/o) resulting in the inability to create a new database session.

ACS SE several databases Windows

Hello

is it possible to have several databases of windows on a SE of GBA? The problem is that we need to access two areas of differentiation, which are not approved and have no great area.

Thanks a lot and best regards

Dominic

Hello

We would require both approval of external/transitive way between the two domains.

There are 2 ways to work around the problem:

1. install an another ACS to the remote site/domain and route all the

applications for users of the remote domain to the ACS.

2 configure the partner domain as LDAP on GBA (Corp. website), this should not require domain trust. The only problem that we will have some authentication methods is not supported when using ldap.

Here is the complete list of stuff that is supported by LDAP:

APEX 4.2.6 Upgrade with unique ORACLE_HOME supporting multiple databases

We have a single server (Solaris) with a single ORACLE_HOME supporting multiple databases (all the 11.2.0.3 with APEX 3.0.2 installed). A new database was created here just to make the development of the APEX. It must be upgraded to APEX 4.2.6. None of the old databases use APEX. Upgrading replaces $ORACLE_HOME/apex. What is the upgrade on the pre-existing database? They will also release APEX upgraded? Thank you.

Hi Michael,

If I understand your question, you want to upgrade APEX in the instance of a database. Fix?

The upgrade of APEX can be done in a database without affecting other databases. Simply run the apexins.sql script in the database when you use APEX.

Regarding the images in your $ORACLE_HOME/apex, it depends on the configuration of your Web server. You can configure your webserver (ADR, OHS, EPG) to get the images in the same directory or in another.

Licenses of the impact on several databases

Licenses of the impact on several databases
We want to create a separate database for one of our departments, we do not want manage their calls and call volumes, in our Technical Service.
Infra allows this, but what is the implications of the license when you do.
Do you need a key to separate license for users on the new system or it will pick up the license on the normal system file
and deduct the totals of this licenses when new users connect?
Kind regards
Christians of Merlin

Hello

We asked VMWare this question last year. Basically, you are allowed to install VSM systems as much as you want to test/development purposes but each live/operational system requires it's own license (from a license point of view).

Several database watch over FAL_SERVER and FAL_CLIENT parameter in DG
Hello

I'm a little confused about FAL_SERVER and FAL_CLIENT parameters in Data Guard.

We intend to set up several database backup in the Data Guard environment. Suggest that I have db production named "PROD" and the name of multiple standby as standby1, standby2, standby3.

Is my environment:_
DB version: 11.2.0.1
OS version: OE5LU6

So in this case, the specification above Net name spfile on production server as well as on the other standby server.

Kindly suggest me.

FAL_CLIENT is the service Oracle TNS from the local system and FAL_SERVER service Oracle TNS from the remote system.
If you have three bases of the pending primary, then the primary data, you must have three values in FAL_SERVER for archives will be send to all destinations.
and the stadnby database, FAL_SERVER must be the oracle TNS service where receive you archives log files.
Note:-If you have primary CARS then forget every service differentiated by commas, as shown below.
Sleep mode to primary CARS:-FAL_SAERVER = "PROD1", "PROD2".
These parameters are dynamic, so that you can change them at any time.

Creating user in several databases
Hi all

I want to create a user in several databases (100 +)

Could someone can share the script.

Oracle DB Version - 9.2.0.6,9.2.0.7 & 10.2.0.2

OS - Hp Unix.

Kindly help out me of this.

Thank you
RAM.
Since you need to connect to all databases individually, I'm not sure that any script would be of no use. And besides, it's just a command then why you want as a script? The best way of IMO would be to configure the EM (Grid Console) and make the creation of the user from there.

Can join us the tables of several databases in the PRD file?
Hello
I'm working on the POC project and try to join several databases to create a file of RPD. Lets say I have complete SH schema from Oracle and I want two or three paintings (time and products) from Sybase.
I want to put sybase TIME and product of the tables in the Oracle SH schema and create joins in the physical layer. When I try to do, it is throughing a mistake... Am I missing something here?

Is this possible?

Thank you

Shivaji
You did not mention what the error!
We can create b & w to join tables in different databases
You must select a database table and as well as another table in the database and
Right click > physical join > selected tables only...

This is how to create physical joins... or else you databases and select physical joins...

It is preferable that you mention, what is the error you get... ??

How to install several databases backup

I have to install multiple standby databases using Data Guard. Here are my questions:
1. What is is the key parameters to take care of?
2. We're adding newspapers of recovery for the day before on the primary, we need to add two sets of newspapers of recovery for data bases from the day before 2?
3. How the Data Guard identify what redo log is add to watching?
4. Y at - it any parameter value for set for newspapers waiting to roll forward in the event of multiples of the day before?
Kind regards
Neeraj G.

Mahir,

You are correct, but according to section 3.1.3 set up a standby Redo Log, for example 3-2, adding a Standby Redo Log File Group to a specific group number

Note:

Although forward redo log is used only when the database is running in the standby role, that oracle recommends to create a log waiting to roll forward the primary database so that the primary database can switch quickly to the role of Eve without the need for intervention extra s/n. Consider using Oracle Enterprise Manager to automatically configure newspapers waiting for Redo on your databases and relief.

Highlight lines above confused me. I added standby redo log on primary which is correct, as stated above. But that work in several cases also ensures?

Kind regards

Can a database instance cause several database schemas?

Since coming from SQL Server I have red the concept of the Forum and got a little confused with the instance, schema, tablespace concept.
If I get it up to now, Oracle has several layers.
Database instances are as independent SQL servers started from the Oracle server.
Each database instance can contain different data bases. OR a database is not owned by a histance, the mountain just a (confused about this)
Each database can have different storage spaces.
I created this pixture comparison, something like that?
http://img191.imageshack.us/img191/7639/jv3z.jpg
- a single instance can open a database only
- on the other hand, a database can be opened by multiple instances on different servers in a clustered (RAC) environment
- a database can have mutiple patterns (that's what SS called "database")
- Each schema has objects that reside in one or more storage space (a single object is always 1 tablespace)
- A tablespace is just a logical container
- A tablespace is composed of one or more data files.

Using the oracle same House for several database (configuration database)
Hi guys,.

I saw a few shops use the same Oracle_home to Multiple Instances of the database...

Basically, they install binaries 11G or 10G once for example: /u01/app/oracle/product/10.2

For the following database facilities they do not install the binaries... they just point the new home of the oracle database to what they currently have...

for example

cat/etc/oratab

newdb:/U01/app/Oracle/product/10.2

So I was wondering if someone could give me the right steps to do this or a metalink note...

Thanks in advance

Here's what I think below:

Step 1

Enter the new name of the database in/etc/oratab... pointing right oracle_home as below

Step 2

Use DBCA or scripts to create the new db

Please, please provide the right steps or metalink note

Please, please provide the right steps or metalink note

You cannot create a database without using the binaries already installed in an ORACLE_HOME. However, all THE databases are created in an existing OH. No matter if you have one or a hundred ORACLE_HOMEs, the procedure is the same:

1 - set ORACLE_HOME, ORACLE_SID and path suitable for the new db. Of course, if you only have a single ORACLE_HOME, you would choose it. If you have more than one, you choose the one you think is appropriate for this new db.
.
2. create the db. You can use dbca, or connect to an idle instance and run scripts that you saved for this purpose. DBCA is a very good and very practical tool, but is not required. It's use is come with a few caveats.

3 - update the oratab accordingly, if you wish (I always thought). Do you understand how and when oratab is used, and why I say update ' If you see is '?

The list of all URLS of OEM for a server with several database

You can get it in two ways:

1 export ORACLE_SID = sid_name

emctl status dbconsole

2. check the file $ORACLE_HOME/hostname_sid/sysman/conf/emd.properties

Site search using several database tables

I am able to search my site for certain keywords using a single database table for example I can search for the butterflies using butterflies search table list. However I would like to have a global search for all types of wild animals on my ex of site from visitors to the homepage can search all species with the word Green in the name. If the search function needs to look at a range of tables, for example floralist; fungilist etc. I have problems with the sort code - I'm a bio-scientist a programmer so any suggestions would be appreciated.

Here is my code for the search using a single table:

  <?php
if (!function_exists("GetSQLValueString")) {
function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "") 
{
  if (PHP_VERSION < 6) {
    $theValue = get_magic_quotes_gpc() ? stripslashes($theValue) : $theValue;
  }
  $theValue = function_exists("mysql_real_escape_string") ? mysql_real_escape_string($theValue) : mysql_escape_string($theValue);
  switch ($theType) {
    case "text":
      $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
      break;    
    case "long":
    case "int":
      $theValue = ($theValue != "") ? intval($theValue) : "NULL";
      break;
    case "double":
      $theValue = ($theValue != "") ? doubleval($theValue) : "NULL";
      break;
    case "date":
      $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
      break;
    case "defined":
      $theValue = ($theValue != "") ? $theDefinedValue : $theNotDefinedValue;
      break;
  }
  return $theValue;
}
}
$colname_search11 = "-1";
if (isset($_POST['species'])) {
  $colname_search11 = $_POST['species'];
}
mysql_select_db($database_cjwebsite, $cjwebsite);
$query_search11 = sprintf("SELECT * FROM `moths searchl ist` WHERE species LIKE %s", GetSQLValueString("%" . $colname_search11 . "%", "text"));
$search11 = mysql_query($query_search11, $cjwebsite) or die(mysql_error());
$row_search11 = mysql_fetch_assoc($search11);
$totalRows_search11 = mysql_num_rows($search11);

followed by:

<div class="results">

Hi Chris,

If the fields are basically the same for all the tables, seems, it would be better to merge them into a single table of "wildlife" and add a field "category", in this way you only ever have to query this table even if several categories are added, each record would have a unique id, and you could open up opportunities to do research with no dependents drop-down menus (i.e. a drop down menu allows the user to select) a category and then will fill up with the category-based species).

It wouldn't be too hard to create the new table, but I wonder how many other elements of your site could be affected by the change.

Hope this helps,

Greg
