Guaranteed restore point Vs catdwgrd.sql downgrade for oracle 12c

I understand that we have two ways to downgrade (assuming compatible parameter is not modified) when we upgrade a 11.2.0.3 database to oracle 12c.
I am curious to know advantages of catdwgrd.sql when compared to guaranteed restore point downgrade. I think guaranteed restore point looks very simple
compared to catdwgrd.sql. Also I think oracle doesn't exactly bring the database back to the same state when we use catdwgrd.sql whereas
guranteed restore point brings us back to the same state.
Thank You

A third possible option is to simply restore the database from backups

Guaranteed Restore Point

I did set a guaranteed restore point for the database which was a business requirement and after a while the database had to be bounced and then restarted. I know that the restore point will still be there. But now my concern is do I have to create a new restore point after the database restarted or will the one created before the bounce will be good if I have to restore a database?

A guaranteed restore point will stay FOREVER until you manually drop it. It will stay across restart.
But now my concern is do I have to create a new restore point after the database restarted or will the one created before the bounce will be good if I have to restore a database?I think you are missing the point of a Restore Point as opposed to a Backup.
A Restore Point is a label for a SCN. If you make a Guaranteed Restore Point, Oracle will retain the flashback logs for as long the restore point exists so it can FLASHBACK (and not RESTORE) to that SCN. You do it before you want to do a big change in database and want to have a mean to rollback the database very fast if something goes wrong. You DO NOT create Guaranteed restore points and leave it there for long time. You take a BACKUP for this purpose.
Creating a new Restore Point is unrelated to the old one and in your case looks unnecessary.

Create guaranteed restore point in oracle 10g RAC ASM

Hi DBAs,
In our production environment we have 2 node master RAC database (Oracle 10.2.0.5) (node1 name=master1 and node2 name=master2)
for which there is going to be a release tonight so want to create a guaranteed restore point for this RAC database.
I have googled many and found some ways, but before I implement it wanted a reviews from experts here.
Note: We already have db_recovery_file_dest set up in ASM...db_flashback_retention_target=1440 and db_recovery_file_dest_size=200GB with arch mode ON.
The steps are
STOP the RAC Database on Both Nodes...
Node1:
$srvctl stop database -d
$Srvctl stop database –d master1
Node2:
$srvctl stop database -d
$Srvctl stop database –d master2
And now start one instance only in mount state:
On node1:
SQL> startup mount
Now enable flashback on Node1...
SQL> alter database flashback on;
SQL> alter database open;
SQL>CREATE RESTORE POINT before_upgrade GUARANTEE FLASHBACK DATABASE;
Now start the second instance…
$srvctl start instance -d -i
$srvctl start instance –d master1 –d master2
Please let me know if there is something needs to be rectified.
Regards,
Ritz

The steps look fine.
Presumably you've already checked to see if the database is in flashback mode and it isn't...hence you putting it into flashbac mode?
Probably just typos but it looks like you have interchanged database names and instance names in your commands....you have the following commands. The srvctl commnds can be run from any node (ie you do not have to run it on node1 to shutdown instance1 and node2 to shutdown instance2).
Node1:    srvctl stop database –d master1
Node2:    srvctl stop database –d master2
You would run either:
Any node:    srvctl stop database -d master (assuming you database name is master...this will shut down both instances)
OR shutdown each instance individually
Any node:    srvctl stop instance -d master -i master1
Any node:    srvctl stop instance -d master -i master2
Same commnds as above to start using "srvctl start"...the following start commands do not look right to me:
srvctl start instance -d -i
srvctl start instance –d master1 –d master2

Help out:SQL Assistant for oracle

Any time i use the logminer utility from the SQLaps SQL Assistant for oracle to query either my redo or archive logs i get this error, but the dictionary.txt file exist in the location specified;
Please help out with details on how to solve this error:

Does anybody have ideas on how logminer utility works using this software "SQL Assistant for oracle""SQL Assistant for Oracle" doesn't seem to be a tool provided by Oracle, but a third-party tool. Therefore I suggest you contact their technical support for your inquiry.
As a workaround, as already suggested, you might want to use the DBMS_LOGMNR package to use the LogMiner. It's not that complicated at all and just needs a couple of calls to the DBMS_LOGMNR and optionally DBMS_LOGMNR_D packages. You can check the documentation on how to use it.
If you have Oracle Enterprise Manager you could access the LogMiner interface using the Java Console version prior to 11g.

Good computer system for Oracle 12c

Hi,
Presently I have one old PC at my home for learning and testing purpose. Now, it seems me very old and slow, so I am planning to buy a new desktop (Not laptop) for learning and testing purpose. I wish to run Oracle 12c, RAC, Data Gurad, ASM, Cloud control, Oracle linux in Oracle VM Virtualbox. Apart from these, I wish to run SQL Server 2012, Windows Server 2012, dot net 2012 Prof Edition and some other softwares. So, please tell me what should be good enough configurations for the PC i.e. HDD, RAM, Processor, Mother board, so that at least it should be good enough for next 5 years.
Thanks.

Yes, and this is what I am asking that what should I ask them to have in it.
You are being too picky and to be honest, if you are planning to buy a system for practice. this is way too much of being fussy. Ask vendors around your area suggest you for an Intel Core-i7 or Xenon , a motherboard that can support at least 32gb of RAM and hard drive options. Now do NOT ask us to give you links . This is simply being lazy. Search and read reviews from different sites. Make up your mind and go for it. To be honest, I am not sure that why you are stuck up in Intel, AMD when somewhere above, you yourself has mentioned this,
"I guess, Intel's processor and motherboards are the best; of course they are high priced; 45% higher than AMD, but 65% more performance"
So seems like you do have a favorite here. Then what's the fuss, go for it. You are not making a machine to support a 24/7 system on which lives would depend, are you?

What are the Oracle Home and GRID home directory locations for Oracle 12c (12.1.0.5) release

Hello All,
I plan to install and configure Oracle 12c Cloud Control console on a single standalone server and the version is Oracle 12.1.0.5. All the databases which are installed across in the entire farm/landscape are these versions:
Oracle 10.2.0.3 Enterprise Edition
Oracle 10.2.0.4 Enterprise Edition
Oracle 10.2.0.4 Active DataGuard Enterprise Edition
Oracle 10.2.0.5 Enterprise Edition
Oracle 11.2.0.1 Enterprise Edition
Oracle 11.2.0.1 Active DataGuard Enterprise Edition
Oracle 11.2.0.3 RAC Enterprise Edition
All Oracle databases across these versions will use the same version of Oracle Grid since ASM is used for all the Oracle database across Production/Test/Development databases. The OS is RHEL 5.8, RHEL 6.3, OEL 6.3 versions.
When installing the Oracle 12c Cloud Control what is the Oracle and Grid Home directory location need to set to. Please let me know if there are any other additional configurations needed?
Looking forward to hearing from you soon.
Regards,
Abhijit

First off, the only EM CC release out right now is 12.1.0.2, not sure where you got 12.1.0.5 (DB Plugin maybe?).
Second, you're confusing EM CC homes with DB/Grid homes.
EM CC will need it's own Oracle Home (i.e. /opt/oracle/product/em_12.1.0.2). You will need to provide repository database connection information, but EM does not care what home the db or grid is installed in.
I would recommend reviewing the documentation as well as the references on OTN -

Maximum number of services for Oracle 12c

can someone please give me a hint where I can find the limitations for number of services on Oracle 12c?
In the reference guide I found: maximum number of services per instance = 115
But that cannot be true because you can have up to 252 pluggable databases per database and each one is associated with a dedicated service.
If done some trials and currently I'm at 556 services. But I cannot find a document with the exact maximum.

Hi Friend,
Two Types containers are available in Oracle Database 12c
1. The ROOT container - - > This is first container and mandatory container.
2. Pluggable Database Container - - - > This is the container for application
So, Limit is - - > 253 PDBs in a One Container Database (CDB) it includes the SEED also and Services are 512 in a Container Database (CDB).
Check the following query to know the number of services
Select name, pdb from cdb_services;
Hope it helps...
Thanks

Refining SQL Replacement for Oracle's WM_CONCAT Function (Pivoting Rows to column)

Greetings,
I am moving a query from Oracle SQL to Microsoft SQL and am having some difficulty with the transition. Part of my code (listed here) used to pivot the data and display RESULT_VALUE
by the CPI_SEQ . In Oracle this was easy to do by using the function: WM_CONCAT.
I have been ‘Googling’ for the non-Oracle way to achieve this and stumbled on to the “STUFF((SELECT…)”
method. This almost works for me except that it places everything into one cell, whereas
I need to concatenate RESULT_VALUE by CPI_SEQ (the CPI_SEQ is the unique ID). The current code gives me this:
RESULTS
Anxiety, Depression, Diabetes,
COPD, ARDS
Whereas I want my code to present it this way instead
CPI_SEQ
RESULTS
22
Anxiety, Depression
44
Diabetes
46
COPD, ARDS
SELECT (STUFF((SELECT ',' + RESULT_VALUE
FROM
SELECT DISTINCT
C1.CPI_Seq AS CPI_SEQ,C1.Result_Value AS RESULT_VALUE
,count(FCurrent.Field_Name) "Current"
,count(FPast.Field_Name) "Past"

,CASE
When count(FCurrent.Field_Name) > 0 and count(FPast.Field_Name) >0 and count(Fcurrent.Field_Name)+ count(FPast.Field_Name) = Count(C1.PF_RESULT_SEQ) Then CONCAT(C1.Result_Value,'(C/P)')
When count(FCurrent.Field_Name) > 0 and count(FPast.Field_Name) =0 and count(Fcurrent.Field_Name)+ count(FPast.Field_Name) = Count(C1.PF_RESULT_SEQ) Then CONCAT (C1.Result_Value,'(C)')
When count(FCurrent.Field_Name) = 0 and count(FPast.Field_Name) >0 and count(Fcurrent.Field_Name)+ count(FPast.Field_Name) = Count(C1.PF_RESULT_SEQ) Then CONCAT(C1.Result_Value,'(P)')

SQL Interface for Oracle in Windows 64 bit

Hi there,
Is there anyone ever trying to upload data from oracle (relational sql) to the essbase on Windows 64 bit platform ? I've read the documentation about setting SQL Interface by using the ODBC Connection ( using DataDirect Library ), but it seems that I can not see the DataDirect lib in the ODBC Control Panel (64bit), but it is installed in the 32 bit ODBC (odbcad32.exe).
However when I try to add new connection using MERANT OEM 5.2 64-BIT Oracle ODBC driver (DataDirect lib), it raise error : "the setup routines for the MERANT OEM 5.2 64-BIT Oracle ODBC driver could not be loaded due to system error code 193"..
please advice any one.... thanks

I got it to work!!!
The reg setting that is provided is for the wrong version of the dll. Notice the 5.1 and then you only have 5.2 directories.
The files in the reg are also wrong they are for the example below. arora21.dll (stated) vs arora22.dll (one's provided)
Some easy tweaks.
I modified the reg with the following and presto. It worked!! To make it better you can change the OEM 5.1 to OEM 5.2.. Good luck

Can I change the SQL Datatype for Oracle Date?

xMII 11.5 maps Oracle's Date type to its SQL type code 91 (Date). When used in a display template, this xMII type displays only the date component (for example, "5/5/2007"), but in Oracle it holds the date and time. In Java, the java.sql.Date type also holds the time component. To get xMII to display a date/time (for example, "5/5/2007 11:23:59") you must have a SQL type code of 93 (Timestamp).
Is there any way to get my xMII widgets to show the date and time components of an Oracle Date? Is there a mapping of some kind that tells xMII which database SQL types map to which xMII SQL type codes?
-tim

In Aqua Data Studio:
SELECT CREATED_DATE_TIME, MESSAGE FROM COLLABORATION_LOG
where CREATED_DATE_TIME > to_date('01/01/07','mm/dd/yy') and site='DEM1'
order by CREATED_DATE_TIME DESC
GO
results:
CREATED_DATE_TIME   MESSAGE
5/3/2007 8:30:25 PM   (403)Access Forbidden
5/3/2007 8:30:25 PM   (403)Access Forbidden
5/3/2007 8:30:25 PM   (403)Access Forbidden
If I put the exact same SQL (without the "GO" at the end which is an Aqua Data Studio keyword) into a Fixed SQL Query in xMII and click "Test" and choose html format I get:
CREATED_DATE_TIME MESSAGE
05/03/2007 00:00:00 (403)Access Forbidden
05/03/2007 00:00:00 (403)Access Forbidden
05/03/2007 00:00:00 (403)Access Forbidden
The time component is reported as "00:00:00" in xMII which is not the desired result. I want xMII to see that column as a Timestamp which should read and sore both the date and time components in xMII.

I need OrderEntry schema SQL file for Oracle 10g Express

I think its doable:
1) http://www.oracle.com/technology/obe/obe1013jdev/common/OBEConnection.htm
Download the sample_schema_scripts9i10g.zip
Since you have Oracle Express you should unzip it to :
C:\oraclexe\app\oracle\product\10.2.0\demo
Thereafter copy
C:\oraclexe\app\oracle\product\10.2.0\demo\schema\order_entry
to

then :

oduct\10.2.0\server\BIN
C:\oraclexe\app\oracle\product\10.2.0\demo\schema>sqlplus system/manager
then
@mksample as described in http://www.oracle.com/technology/obe/obe1013jdev/common/OBEConnection.htm
I agree with you that this was not straight forward since these scripts are pretty complex, but I did this now and I have at least the customer - orders relation up and running so I hope it helps.
