Manaul steps to create RAC ONE database

Hi I am trying to create to the RAC one database mnaually without using dbca utility.
Can anyone please let me know the steps to to create RAC one node database.
I am able to find lot of doucemtnation on net for the steps to create RAC database but unable to get on RAC ONE nodate database.

As John said, Setting up RAC one node is same as 2 nodes RAC . You need to define some parameters . Please follow the Oracle link and it explains very well.

you have now two different pfiles: one in c:\temp\initstdby4.ora. and %ORACLE_HOME%\database\initstdby4.ora.
You are using the latter, as you didn't specify pfile= in your startup mount.
Also, if you are using a spfile, the only line in a pfile should be: spfile=....
In your pfile you are mixing up Unix like file locations with \ and Windows file locations with /
Could you please read the docs

Rac One Node on Rac Servers

Hi Xperts
We have this environment:
2 Rac Nodes 11.2.0.3 Enterprise on Oracle Linux 5.9 .
We have one production Database on this Rac and the users ask to create two single instance on each node, something like this:
Node1 -> Rac Prod1, Single Test
Node2-> Rac Prod2, Single Dev
I want to create Rac One node for those Database (Dev, Test) and create New Diskgroups for ech database.
Can I install a Rac One node on those Server with DBCA?
Do I nedd to Install new Database Software ?
Does the installed Rac have some affectation ?
I just want to be sure about this procedure, before to do anything.
Thank you
J.A.

Hi J.A.
Yes you can! However you need to install Grid Infrastructure (GI) in cluster on both nodes, then install database software. Either during software installation or after that, DBCA would allow you to create 1) Single instance, 2) RAC database, 3) RAC One Node database. Keep in mind that RAC One Node is an option (additional license) to the Enterprise Edition of Oracle Database.
I've talked on that topic at the Bulgarian Oracle Users Group at 2011, here is the link to the presentation, you may find it useful. I might upload the videos as well if you need to have something like a proof of concept of just for your own:
http://sve.to/download/1112/
Also I would go with one disk group for both databases, as long as they share the same physical disks I don't see the point of doing that ? Having one diskgroup would allow you to utilize better you disk/space resources.
The procedure would be:
1. Install GI in cluster.
2. Install software libraries.
3. Patch up to 11.2.0.4.
4. Create RAC One Node database using either command line or using Custom Template of DBCA.
At the end of the day, if you have standard edition license you can still install GI in cluster and create single instance databases on each server. The downside of doing that is that you need to manually failover the database to remaining node in case of disaster.

Steps to create LOGICAL DATABASE in sap

hi guys,
i have gone through many documents about LDB. But, i didnt get the steps to create a LDB.
plz provide me with the steps to be followed to create a LDB.
thnx,
shivaa.

Hi Shiva,
This might help you!
Logical database structures
There are three defining entities in an SAP logical database. You must be clear on all three in order to create and use one.
Table structure: Your logical database includes data from specified tables in SAP. There is a hierarchy among these tables defined by their foreign keys (all known to SAP), and you are going to define a customized relationship between select tables. This structure is unique and must be defined and saved.
Data selection: You may not want or need every item in the referenced tables that contributes to your customized database. There is a selection screen that permits you to pick and choose.
Database access programming: Once youu2019ve defined your logical database, SAP will generate the access subroutines needed to pull the data in the way you want it pulled.
Creating your own logical database
ABAP/4 (Advanced Business Application Programming language, version 4) is the language created by SAP for implementation and customization of its R/3 system. ABAP/4 comes loaded with many predefined logical databases that can construct and table just about any conventional business objects you might need in any canned SAP application. However, you can also create your own logical databases to construct any custom objects you care to define, as your application requires in ABAP/4. Hereu2019s a step-by-step guide:
1. Call up transaction SLDB (or transaction SE36). The path you want is Tools | ABAP Workbench | Development | Programming Environment | Logical Databases. This screen is called Logical Database Builder.
2. Enter an appropriate name in the logical database name field. You have three options on this screen: Create, Display, and Change. Choose Create.
3. Youu2019ll be prompted for a short text description of your new logical database. Enter one. Youu2019ll then be prompted to specify a development class.
4. Now comes the fun part! You must specify a root node, or a parent table, as the basis of your logical database structure. You can now place subsequent tables under the root table as needed to assemble the data object you want. You can access this tree from this point forward, to add additional tables, by selecting that root node and following the path Edit | Node | Create. Once youu2019ve saved the structure you define in this step, the system will generate the programming necessary to access your logical database. The best part is you donu2019t have to write a single line of code.
Watch out!
The use of very large tables will degrade the performance of a logical database, so be aware of that trade-off. Remember that some tables in SAP are very complex, so they will be problematic in any user-defined logical database.
Declaring a logical database
Hereu2019s another surprising feature of logical databases: You do not assign them in your ABAP/4 Code. Instead, the system requires that you specify logical databases as attributes. So when you are creating a report, have your logical database identifier (the name you gave it) on hand when you are defining its attributes on the Program Attributes screen. The Attributes section of the screen (the lower half) will include a Logical database field, where you can declare your logical database.
Logical databases for increasing efficiency
Why else would you want to create a logical database? Consider that the logical databases already available to you begin with a root node and proceed downward from there. If the data object you wish to construct consists of items that are all below the root node, you can use an existing logical database program to extract the data, then trim away what you donu2019t want using SELECT statementsu2014or you can increase the speed of the logical database program considerably by redefining the logical database for your object and starting with a table down in the chain. Either way, youu2019ll eliminate a great deal of overhead.
Reward if useful.
Thankyou,
Regards.

Question about DBCA generate script o create RAC database 2 node cluster

Question about creating two node RAC database 11g after installing and configuration 11g clusterware. I've used DBCA to generate script to create a rac database. I've set
environment variable ORACLE_SID=RAC and the creating script creates instance of RAC1 and RAC2. My understanding is that each node will represent a node, however there should only be one database with a name of 'RAC'. Please advise

You are getting your terminology mixed up.
You only have one database. Take a look, there are one set of datafiles on shared storage.
You have 2 instances which are accessing one database.
Database name is RAC. Instance names are RAC1, RAC2, etc, etc.
Also, if you look at the listener configuration and if your tnsnames is setup properly then connecting to RAC will connect you to either one of the instances wheras connecting to RAC1 will connect you to that instance.

Differences in creating a Standby database in RAC

Hi All
   SO...: Solaris 11 SPARC 64
   DB...: 11.2.0.3.6 (64 bits)
   My experience regarding creating Physical Standby Databases is restricted in only single instances to single instances. I am reading the book "Oracle Database 11g Release 2 High Availability", but, in parallel, i would like to hear from the experienced DBAs here some opinions and recomendations in how to implement a RAC to RAC solution. Below are my doubts:
   1) In single instance, using RMAN Backup to create the Physical Standby, i have to create manually a static Listener Entry. But in a RAC env, the listener is a resource, so, i have to create that resource in the Clusterware manually, or there is other approach?
   2) I have to create a pfile and start the instance in NOMOUNT mode, but in RAC, i have to start all the nodes in NOMOUNT, or just one node is sufficient?
   3) The archives will be replicated from FRA to FRA. Is this the best approach?
   My main concern is with the Listener and SCAN questions... If you have any considerations, they will be most welcome.
   Thanks in advance.

Steps to create database link

i got these info from my teacher to create database link
1.     Establish the network connection.
2.     Shutdown the database. (SQL>shutdown immediate ;)
3.     Open and modify the pfile and set GLOBAL_NAME = FALSE.
4.     Create spfile from pfile. (SQL>create spfile from pfile;)
5.     Startup database. (SQL> startup;)
6.     Modify tnsnames.ora file, set the destination computer service name and other in formations.
ASIF.com =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = ONE)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = ORCL)
7.     Crate database link .
SQL>create public/private database link abc
     Connect to scott
     Identified by tiger
     Using asif.com;
in step 3, which pfile should i modify
i got a file in F:\oracle\admin\fahmi\pfile named init.ora.31620060327
but there is no line like GLOBAL_NAME = FALSE
so watching the sample i add this line in init.ora.31620060327
global_names = FALSE
am i right...........??
can anyone help me...??
i have some few other questions.....................

The following is an excerpt from http://www.oracleutilities.com/OSUtil/ping.html
The tnsping utility is used to determine whether or not an Oracle service can be successfully reached. If a connection can be established from a client to a server (or server to server), tnsping will report the number of milliseconds it took to reach the remote service. If unsuccessful, a network error will be displayed. However, tnsping will only report if the listener process is up and provides no indication of the state of the database.
$ tnsping <net service name> <count>
The net service name must exist in the tnsnames.ora file. This file is used by clients and database servers to identify server destinations. It stores the service names and database addresses. The count parameter is optional and will show the number of times the command should try to connect to the specified service name.
After this I suggest you to check your $ORACLE_HOME/network/admin/sqlnet.ora.
Look for what is configure for:
NAMES.DEFAULT_DOMAIN
NAME.DEFAULT_ZONE
This must be compatible to what you are using in your tnsnames.ora.
By the way, don't forget to check if there is a log file (sqlnet.log) in your $ORACLE_HOME/network/admin directory.
Regards.

ORA-24544 When Creating a Standby From RAC One Node

I have a RAC One Node database running on node A and am attempting to create a Data Guard standby on node B using the following RMAN command -

Can anyone advise ?
Thanks in advance

Hi,
ORA-24544: Oracle RAC One Node instance is already running.
Cause: An instance startup failed because an instance of the Oracle RAC One Node database was already running on one of the cluster nodes.
Action: In Oracle RAC One Node, avoid any attempt to start a second instance by any means while the instance is already running.
I have never used One Node RAC, but it looks like RMAN trying to start an offline instance of current One Node RAC on Node B.

Until you provide some hints about operating system for each of the RAC machines, the networking you have installed (and whether you have the interconnect running), the shared disk mechanism (and whether it is confirmed shared raw or ASM), the Oracle software versions, whether your systems passed cluster verify ... we would be wasting our time guessing.

How to create a variance on data that exists iIn only one database column

How to create a variance on data that exists iIn only one database column?
I'm trying to create a calculation to show the difference between the budgets for two different years in a Discoverer crosstab query.
I'm using the lag function to repeat the value of a column for the current year and the year before.

Lag and lead seems to be the only choice and they work excellent. Checkout the new 10g Database features. There is new SQL modal clause which might give additional and powerful analytics but in this case lag and lead should be sufficient.

hi
what are the apps version local and remote database???
Snapshot too old errors occur because Oracle can 't reconstruct a consistent
image of a block for the purposes of a consistent read.
I feel at remote database, you are using UNDO, it will be rather easy to iincrease the undo retention time or increase the undo tablespace size.. if you are dealing with roll back segments, you may have rollback segments whose optimal values are too small...
increase roll back segments size and select again then
the following metalink notes might be helpful
