Query regarding Non-RAC to RAC Migration

Hi,
We are migrating a stand alone 11g R2 Database on Linux x86-64 systems to RAC. Should I move my database files to ASM before running rconfig, or rconfig automatically does it.
Regards,
Charan

Before you convert a single-instance database to an Oracle RAC database, ensure that the following conditions are met for each cluster node that you intend to make an Oracle RAC database node:
Oracle Clusterware 11g release 2 (11.2) is installed, configured, and running.
Oracle RAC 11g release 2 (11.2) software is installed.
The Oracle binary is enabled for Oracle RAC.
Shared storage, either Oracle Cluster File System or Oracle ASM, is available and accessible from all nodes.
User equivalence exists for the oracle account.
If you intend to use Oracle Enterprise Manager, then all Oracle Enterprise Manager agents are configured and running, and are configured with cluster and host information.
You have backed up your existing database.
So the answer is yes, you should.

Steps to Convert R12 Non-Rac to RAC database with ASM

dear All,
We have following environment.
R12.0.6 with a non RAC 11.2.0.2 database on on AIX (64bit). Datafiles are stored local filesystem. We want to do the following.
Migrate the database file to ASM
convert database Non RAC to RAC
we have gone through many oracle support documents but were unable to decide which path we should adopt. Any body who has done similar activity; please share only highly level steps. No step by step Instructions are needed. e.g. Install Grid Infrastructure (for single instance or the one which comes with cluster home???????), Move datafiles to ASM etc etc
Please make sure the steps are for 11gR2 and EBS R12.

Non-Rac to Rac conversion using rconfig

hi all,
how to check whether Non-Rac to Rac conversion using rconfig has been completed sucessfully?
thanks.

Cloning non-RAC to RAC ?

Hi,
Is it true that Oracle does not support cloning of single node instance EBS R12.1 (Non-RAC) to RAC?
Is there other supported way to do it? both using rapid clone or manual?
Thanks a lot
MsK

Hi,
How about the patches needed? Make sure you have the latest Rapid Clone and AutoConfig patches applied on the source instance.
Our source db is 11.1.0.7, and the target db is also 11.1.0.7 ....but there are patches mentioned in 802875.1
Do I need to follow this Note?If you are already on 11.1.0.7, then you do not need to apply those patches.

Non RAC to RAC

Hi,
I need to convert a Non-rac to RAC. Can somebody help me with note or doc for doing this ?
Thx

1. Set the init parameter cluster_database=false (or remove it since false is the default). You'll have to set it in the parameter file since it is not dynamic.
2. Shutdown all instances. Start the one that you want to survive.
3. Cleanup as necessary: remove extra UNDO, REDO files
4. If you want to remove clusterware, that's another whole question. There's a ML article on how to remove clusterware.
5. If your database uses ASM, you'll need to do #1 for the ASM instances as well.
That's high-level, but I haven't seen a complete paper/procedure for this published anywhere yet.

OVM 3.x: cannot migrate guests from RAC to RAC

Hi, all.
I think I have the same problem as in this other thread:
OVM 3.0.2: cannot migrate guests to updates VM servers
But the maintenance mode is off.
Rac 1 and Rac 2 - Maintenance mode is off
Migrate from Rac 1 to Rac 2 - OK
Migrate from Rac 2 to Rac 1 - don't show up as possible migration Targets
Thank you.

Hi Shawn,
In the BW 7.0 release, it is not recommended to use export datasources for the myself datamart extraction. If possible you should use a DTP & a transformation.
Please see the attached Note 989757 for further info.

A query regarding synchronised functions, using shared object

Hi all.
I have this little query, regarding the functions that are synchronised, based on accessing the lock to the object, which is being used for synchronizing.
Ok, I will clear myself with the following example :
class First
int a;
static int b;
public void func_one()
synchronized((Integer) a)
{ // function logic
} // End of func_one
public void func_two()
synchronized((Integer) b)
{ / function logic
} // End of func_two
public static void func_three()
synchronized((Integer) a)
{ // function logic
} // End of func_three, WHICH IS ACTUALLY NOT ALLOWED,
// just written here for completeness.
public static void func_four()
synchronized((Integer) b)
{ / function logic
} // End of func_four
First obj1 = new First();
First obj2 = new First();
Note that the four functions are different on the following criteria :
a) Whether the function is static or non-static.
b) Whether the object on which synchronization is based is a static, or a non-static member of the class.
Now, first my-thoughts; kindly correct me if I am wrong :
a) In case 1, we have a non-static function, synchronized on a non-static object. Thus, effectively, there is no-synchronisation, since in case obj1 and obj2 happen to call the func_one at the same time, obj1 will obtain lock for obj1.a; and obj2 will obtain lock to obj2.a; and both can go inside the supposed-to-be-synchronized-function-but-actually-is-not merrily.
Kindly correct me I am wrong anywhere in the above.
b) In case 2, we have a non-static function, synchronized on a static object. Here, again if obj1, and obj2 happen to call the function at the same time, obj1 will try to obtain lock for obj1.a; while obj2 will try to obtain lock for obj2.a. However, since obj1.a and obj2.a are the same, thus we will indeed obtain sychronisation.
Kindly correct me I am wrong anywhere in the above.
c) In case 3, we have a static function , synchronized on a non-static object. However, Java does not allow functions of this type, so we may safely move forward.
d) In case 4, we have a static function, synchronized on a static object.
Here, again if obj1, and obj2 happen to call the function at the same time, obj1 will try to obtain lock for obj1.a; while obj2 will try to obtain lock for obj2.a. However, since obj1.a and obj2.a are the same, thus we will indeed obtain sychronisation. But we are only partly done for this case.
First, Kindly correct me I am wrong anywhere in the above.
Now, I have a query : what happens if the call is made in a classically static manner, i.e. using the statement "First.func_four;".
Another query : so far we have been assuming that the only objects contending for the synchronized function are obj1, and obj2, in a single thread. Now, consider this, suppose we have the same reference obj1, in two threads, and the call "obj1.func_four;" happens to occur at the same time from each of these threads. Thus, we have obj1 rying to obtain lock for obj1.a; and again obj1 trying to obtain lock for obj1.a, which are the same locks. So, if obj1.a of the first thread obtains the lock, then it will enter the function no-doubt, but the call from the second thread will also succeed. Thus, effectively, our synchronisation is broken.
Or am I being dumb ?
Looking forward to replies..
Ashutosh

a) In case 1, we have a non-static function, synchronized on a non-static object. Thus, effectively, there is no-synchronisationThere is no synchronization between distinct First objects, but that's what you specified. Apart from the coding bug noted below, there would be synchronization between different threads using the same instance of First.
b) In case 2, we have a non-static function, synchronized on a static object. Here, again if obj1, and obj2 happen to call the function at the same time, obj1 will try to obtain lock for obj1.a; while obj2 will try to obtain lock for obj2.a.obj1/2 don't call methods or try to obtain locks. The two different threads do that. And you mean First.b, not obj1.b and obj2.b, but see also below.
d) In case 4, we have a static function, synchronized on a static object. Here, again if obj1, and obj2 happen to call the function at the same time, obj1 will try to obtain lock for obj1.a; while obj2 will try to obtain lock for obj2.a.Again, obj1/2 don't call methods or try to obtain locks. The two different threads do that. And again, you mean First.b. obj1.b and obj2.b are the same as First.b. Does that make it clearer?
Now, I have a query : what happens if the call is made in a classically static manner, i.e. using the statement "First.func_four;".That's what happens in any case whether you write obj1.func_four(), obj2.func)four(), or First.func_four(). All these are identical when func_four(0 is static.
Now, consider this, suppose we have the same reference obj1, in two threads, and the call "obj1.func_four;" happens to occur at the same time from each of these threads. Thus, we have obj1 rying to obtain lock for obj1.aNo we don't, we have a thread trying to obtain the lock on First.b.
and again obj1 trying to obtain lock for obj1.aYou mean obj2 and First.b, but obj2 doesn't obtain the lock, the thread does.
which are the same locks. So, if obj1.a of the first thread obtains the lock, then it will enter the function no-doubt, but the call from the second thread will also succeed.Of course it won't. Your reasoning here makes zero sense..Once First.b is locked it is locked. End of story.
Thus, effectively, our synchronisation is broken.No it isn't. The second thread will wait on the same First.b object that the first thread has locked.
However in any case you have a much bigger problem here. You're autoboxing your local 'int' variable to a possibly brand-new Integer object every call, so there may be no synchronization at all.
You need:
Object a = new Object();
static Object b = new Object();

Query regarding GL

Hi,
We are on R12 and I have have a query regarding balances.
I am writing a report and need to get the functional Actual balance(GBP) for accounts.
Each account has a balance in one or more currencies. My understanding as per the TRM was that the period_net_dr/cr columns stores the balances in ledger currency for all Journals entered and posted in GBP, while the period_net_dr_beq and period_net_cr_beq stores the ledger equivalent balance for all Journals entered and posted in Foreign currency.
However, when I query gl_balances, I notice the following :
1) For a ccid, for GBP currency code, the period_net_dr_beq and period_net_cr_beq are being populated , why ?
2) For certain ccid, for GBP currency code the period_net_cr_beq and period_net_dr_beq both are zero, though there is a value in the period_net_dr/cr columns.
3) When I do an account inquiry from GL SuperUser, I can see that for a given period and account and for Currency type 'Entered' , the Balances window shows me the
result of period_net_dr_beq-period_net_cr_beq columns for my GBP balance.
I am a bit confused and would appreciate if someone can point me what am I missing ?
Thanks

OK, I have managed to figure this one out.
The period_net_cr / period_net_dr stores the sum of functional balances(includes the GBP journals + the functional equivalent of the non gbp journals) . Its like a running total of the functional balance.

Execute query with non database block

How to execute query with non database block when new form instance trigger.

Hi Kame,
Execute_Query not work with non database block. To do this Make a cursor and then assign values to non database block's items programmatically, see following example,
DECLARE
BEGIN
     FOR i IN (SELECT col1, col2 FROM Table) LOOP
            :block.item1 := i.col1;
            :block.item2 := i.col2;
            NEXT_RECORD;
     END LOOP;
END;

Oracle Apps RAC TO RAC cloning from Netbackup(tape)

Hi,
I am doing RAC to RAC cloning on linux 5 following is the note id i follow
Cloning Oracle E-Business Suite Release 12 RAC-Enabled Systems with Rapid Clone [ID 559518.1]
In this note step 4.2 we use adclone.pl to prepare the stage on source using "Method=Rman", i think this creates image backup of the database on source system
In step 5.1.4.1 we restore the database on target using the stage backup we took in source.
So, here i was thinking if it is possible to use Netbackup server (tapes) for "rmanstage=" parameter. Because we don't have that much disk space to accommodate backup and as with Rman duplicate database we directly connect to tape with auxiliary for cloning, Please let me know if we can use this process with the above adclone.pl
Thanks,
Tanveer Mohammed

Hi Tanveer,
Yes what you want is allowed, you are free to clone your DB using rman outside of the cloning utilities.
When you want this make sure you follow:

Query on Non-base-table column in form

Hi,
Does anyone have an example of code to allow users to query on non-base-table column from forms? For example, a personnel form displays a persons' name and department name. The form is based on PERSON table, which contains the department id, not the name. The form uses post-query to display the department name. When in query mode, the user wants to enter department name, and display the people in the department (still using this form, which is based on PERSON table.
Thanks!

Try this:
For data block person set these properties as follows:
1.Set Query Data Source Name = "person , departments"
2.Set DML data target name = "person"
3.Set Where Clause to join i.e. condition "person.dno = departments.dno"
For filed department name set these properties as follows:
1.Data base item = "Yes"
2.Column Name = "departments.dname"
3.Query Only = "Yes"
4.Insert Allowed = "No"
5.Update Allowed= "No"
6.Keyboard Navigable = "No"
If you face ambiguous column name check for the same filed name exist on both tables and set column name for this filed to person.filed_name

Query regarding Pagination

Hi all,
I have a query regarding the Pagination in the table component.I have a table and this table has been paginated with size 5. I am using an ObjectListdataprovider for populating data in table.Here i populate the ObjectList from another page and show it here in another page.Here we can chane the data.when i am clicking on the save it only considering the first 5 values dat is currently showing.This thing happens only when i didn't go the the second page using page navigation buttons.That is it ony saves the data that got focus.Can anyone have any solution?Please help me..
Thanks and Regards
Sree

Do you have a message group component on the page to display runtime errors?
Did you check the server log (right-click Deployment Server and choose View Server Log) to see if any errors show up there?
Do you have any table colomn components bound to non-string fields? If so, did you drop the right type of converters on those components?

DMV quesiton. Can not run the DMV query in non system database.

As the title .I can run following query when I use 'use master' , But don't work at the DB which be created my myself.
--Error massage
Msg 208, Level 16, State 1, Line 1
Invalid object name 'SYS.DM_EXEC_QUERY_STATS'.
--SQL Version : 2005

CROSS APPLY SYS.DM_EXEC_QUERY_PLAN (QS.PLAN_HANDLE) AS QP

Yes, you can run the query under none system database.... Make sure that your db is set 90.....
