Different optimizer paths between two identical databases

Hello!
I'm running into a problem with a query that is pretty amazing. I have two different databases that I work with - Development and Acceptance. According to my DBA, they are absolutely identical in every respect - including data. Both of them gather statistics every night at the same time.
On development my query executes beautifully - 0.6 seconds.
On acceptance the query executes in 60 - 70 seconds.
They both evalute completely differently thought an explain plan - obviously from the difference in performance. Here are the two explain plans for the query...

So I can definitely tune the query to work against my acceptance database - that isn't really the problem. The problem is that I can't count on the optimizations to be the same between development and acceptance. So if I move this to production, how do I know I don't get a third plan?!?!?
Can anyone suggest anything that might cause what I'm seeing above - and / or anything that I can do to prevent it. This is just one query out of 10,000 or so that I'm working with - we are migrating from Oracle 9 to 11g and the queries all worked perfectly on 9.
Thanks in Advance!

ADF BC: Choosing between two identical DB schemas on application startup

Hi,
We want to provide users with capability to choose between two identical db schema.
Anu idea how to do this ?

Cvele wrote:
Thanks a lot ! My pleasure.
One question: datasource name entered by the user (on the login form) is a JDBCDataSource property value for the Application module Configuration (which connect trough JDBC DataSource), correct ?Yes.
If so, then, we still must define two different sets of App Module Configurations, one for each DB schema, correct ?No. I'm not suggesting that you implement your UI like the demo that I forwarded. It might not be appropriate for your user to type in the datasource name, but the same code would be required to make the datasource name change work. Rather than getting the datasource name from the HTTPRequest and setting on the session where the custom sesison cookie impl and env info provider access you, for your solution that datasource value might come from some other place that the end-user doesn't directly type in.
Otherwise:
1. we cannot have two different datasource names, correct ?The example I forwarded should allow you to enter different JNDI names, so those would be different datasources.
2. in case of one Configuration – what is a way to define (at deployment time) username/password for each of those two schemas ? Is this correct ?The username/password information is encapsulated inside the Java EE container when you define the datasource. The application doesn't know that information and doesn't have to provide it when you are using a JDBC datasource by JNDI name.
On the other hand, what confuses me, is a fact that you say:
“You wouldn't use different configurations” And really, you example attached to me have just one App module Configuration (datasource name = jdbc/scottDS), which connect through dataSource.
Wondering what a user can enter as datasource name, except jdbc/scottDS ?I forget whether in my example I configured another datasource, but the user could enter the name of any available JNDI name for the datasource on the Java EE container.
Again, I don't suggest necessarily that you let the end-user type it in, that was just how I built the demo since I quickly evolved it from the other dynamic credentials demo that accepted the username and password from the end-user.

How to delete a path between two anchor points

hi ,
it's all in the title ,
could you tell me please how to delete a path between two anchor points without using the path eraser tool ?
When I select these two anchor points and press delete everything is gone.
ps : I want to keep the anchor points after the deletion
Thank you

Silkrooster wrote:
With some experimentation, I did find that selecting the path can leave orphan points. So keep that in mind as it may be necessary to use Object>Path>Clean up...
You will not get orphan points if you delete a segment that is not at the end of a path. For segment that is at the end of a path, or is the entire path, select the end point/s and press delete. For the one segment that is entire path you can use the selection tool (black pointer) or hold Alt with the direct selection tool (white pointer) which is useful for objects in a group.

Shortest path between two arbitrary point in the network

Hi All,
In oracle NDM, it's possible to find shortest path between two nodes (e.g. using SDO_NET_MEM.NETWORK_MANAGER.SHORTEST_PATH), but I need to find shortest path between 2 points which are on the network edges. I suppose I should use (Interface SubPath) in network java apis. However I want to do it via PLSQL api. Should I code it myself or there exists a function?
Any help is appreciated.

please help some one...pleaseDo you know Dijkstra's Algorithm for shortest path? I believe that one was also called the traveling salesman problem. You can easily Google to find out what it is.
Did you listen to your instructor when he/she did his/her lectures on recursion and halting contitions? If not, then please go talk to him/her and read your book, the forum is not a place to try to learn a basic concept that you should have paid attention in class for the first time.

Best approach to synchronize data between two oracle database remotely

Hi All,
We have requirement to synchronize data between custom application database and EBS database. Thw two database is on different location connected by 128 kbps connection.
The synchronization will do the following task :
- Download customer table from EBS (I have checked there are only 2000 rows of it)
- Up load billing data to EBS auto invoice interface table
The question is :
What approach is the best way to do this synchronization task ? some that come into my mind :
- create database link and run stored procedure to do the batch update ?
- for Customer synchronization, is it a good idea to create Materialized view so that any update to EBS customer data will be updated, refreshed nightly
- or is ther any better approach ?
Thank you very much,
xtanto

Maybe try Streams?

Link two identical databases, same tables, same fields

Post Author: CathyH
CA Forum: Data Connectivity and SQL
I have two Accpac databases (two different companies, one Canadian one US). I have created the same report for both companies using their respective data tables and another where I have converted the US funds to Canadian.
I would now like to create one report that links the two companies.
I will be sorting on Customer. Whenever a customer is set up in the US company a duplicate is set up in the Canadian company but Canadian customers are not duplicated in the US company (it's just something we have to do for billing purposes) so there will always be many more Canadian customers.
I would like the report to add together any matching customers in the US and Canadian companies but also report the customers that are strictly Canadian.
Can anyone help me? Please!

You might do this using advanced SQL on the database in a View or SP.
Or another, somewhat fugly solution is to create a main report with the canadian database, group by the company, insert a subreport using the US database at the group level (header or footer), and link by the company.
You can now respond to no rows in the subreport to indicate those that are not in the US database.
Ain't purdy, but it'll work.

Problem with ORA-06502 when exp/imp between two identical versions

Hi
I have two identical systems, one system that I develop on and
the test system. The two systems have the same version of the
Portal. When I export and then import the application from the
systems I get a error message on the test system.
ORA-06502: PL/SQL: numeric or value error: character to number
conversion error (WWV-11230)
This error does not appear on the developing system.
The application I have is a form on a table, and I have some
buttons with PL/SQL handels on them. I tried to remove this code
and export with no luck.
Please help.
The system:
Windows NT
Oracle Portal 3.0.8.9.8
Thanks
Jvrgen Swensen

Could you pls confirm : Have you exported & Imported the shared
components used by that form?
If you are not too worried about the templates/fonts then try
this:
Click on "Edit" link against that form and click "OK".
Thanx,
Chetan.

Different full backup size of identical databases

Hello,
I am on Oracle 10GR2.
I have 1 database instance with size approximately 50GB. Today I created second instance with RMAN duplication process from the first instance. So now I have two similar DB instances with same size 50GB.
What is strange to me is size of FULL LEVEL0 backups of these databases.
Backup size of original database has approximately 22 GB, backup size of second (duplicated) instance has 7GB.
Can you explain me why? Or what should I do with original database to have same small backup size.
Executed RMAN command for backup is: BACKUP INCREMENTAL LEVEL 0 DATABASE PLUS ARCHIVELOG;
Thank you

select sum(bytes)/1024/1024/1024 GB from dba_segments;
This select gives me 6,79 GB in both instances.
I did not used UNTIL TIME for duplication.
RMAN settings is same for both instances and I don't use any compression
RMAN configuration parameters are:
CONFIGURE RETENTION POLICY TO REDUNDANCY 1; # default
CONFIGURE BACKUP OPTIMIZATION OFF; # default
CONFIGURE DEFAULT DEVICE TYPE TO DISK; # default
CONFIGURE CONTROLFILE AUTOBACKUP ON;
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '%F'; # default
CONFIGURE DEVICE TYPE DISK PARALLELISM 1 BACKUP TYPE TO BACKUPSET; # default
CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE MAXSETSIZE TO UNLIMITED; # default
CONFIGURE ENCRYPTION FOR DATABASE OFF; # default
CONFIGURE ENCRYPTION ALGORITHM 'AES128'; # default
CONFIGURE ARCHIVELOG DELETION POLICY TO NONE; # default

MacBook Pro: Swapping Hard Drives Between Two Identical Macs?

I have two Macbook Pro notebooks. They are both the June 11th 2012 models both with cd/dvd drives. They both have Mavericks installed on both.
I want to give my 15 inch to my son who has the 13 inch. They 13 will be mine and the 15 his.
Can i just swap his 750HD from the 13 and put it into the 15? Can i also remove my 250 Samsung pro SSD from my 15 and put it in his 13?
What are some ways i can go about this that are easy?
Thanks in advance,
PS: Like i said they both run mavericks and they are the same generation MBP from June 2012 release from Apple. Except one is a 2.5 i5 13 inch and the other is a 15 inch 2.3 Quad i7.
We pretty much just want to trade laptops and swap the hard drives easy.
Thanks again.

nn007400,
are each of your laptops associated with your respective Apple IDs? If so, then that might be a fly in the ointment when it comes to updating apps purchased through the Mac App Store, if the tie-in involves your MacBook Pros’ serial numbers as well as your Apple IDs. (I don’t know whether that’s the case or not.)
The disks can certainly be exchanged physically between the two portables — you could try it for a while, and if you encounter a problem, you can exchange them back and consider alternative (but unfortunately less convenient) approaches.

Application to compare differences between two identical drives..

Hi,
I'm after an application that can be used to compare two separate drives (or better then that, specific folders on two separate drives), supposedly with the same files on each, and analyse the differences between the two (ie I want to make sure everything has copied from one to the other succesfully before deleting the original!)
It's quite a large amount of data (500GB), and I don't need the software to actually do anything other than tell me the differences - nothing like copying the missing files is needed. I had to intentionally leave a few files behind as they were causing errors in the copying process.
Any suggestions? Thanks!

I am using the FormsTool V1.0 from the previously mentioned http://www.orcl-toolbox.com This is a great tool for doing diffs on Forms and Reports. It has saved me several times in the past. Never had the need for the replace functionality but I am sure it is just a matter of time.
Also great for doing impact analysis when someone wants to change something and wants to know how many forms/reports are impacted.
Well worth having a copy for the $200 cost. No I do not work for orcl-toolbox ;-)
Bob.

How to seperate the access for two identical databases from two application

First I have to say I'm sorry... Oracle and the oracle architecture are totally new for me. However I hope to get some help with this.
We have one Oracle 10g server and a database name A with table name X, Y and Z, for Application AA with access for property file AAA.
The server capacity are almost not being used.
Here are my thought, how can I add a database name B with table name X, Y and Z (yes same tables as in database A) data for application BB with access for property file BBB.
how can I seperate the 2 property files (question: on a port number?), so in case there by a mistake should be switch around on 2 property files, it then is impossible to access the date from Application AA to date in database name B.
Password on Database A (incl table) and Database B (incl table) are the same.
Is there any solution to this?

What I would like to do is make use of the resource on one machine.
I have several similar applications, databases, tables and password where data should be totally separated from each other. however I would trying to prevent that there could be any data access from Application AA to Database B in case there should be a switch of property files
I'm familiar with Sybase environment, however isn't there some thing fancy in oracle there can seperate to almost identical applications to access other databases

Finding Paths Between Two Nodes Using SQL Sorted by Cost

Hi Gurus,
I want to find all paths from source node to target node that shall be sorted by the cost. I don't know whether it could be achieved with SQL statement. How to start with this query? The script to create the underlying tables along with the data are given below:
create table nodes ( nodeId int Primary Key, nodeName varchar(50));
create table paths ( pathId int Primary Key, fromNodeId int, toNodeId int, cost int );
insert into nodes values (1,'ISL');
insert into nodes values (2,'LHR');
insert into nodes values (3,'HYD');
insert into nodes values (4,'FSL');
insert into nodes values (5,'MUL');
insert into nodes values (6,'KHI');
insert into nodes values (7,'QT');
insert into paths values (1,1,3,20);
insert into paths values (2,1,5,10);
insert into paths values (3,1,7,80);
insert into paths values (4,2,4,10);
insert into paths values (5,3,4,40);
insert into paths values (6,3,5,20);
insert into paths values (7,3,6,10);
insert into paths values (8,6,7,30);
insert into paths values (9,6,5,30);
insert into paths values (10,6,3,10);
insert into paths values (11,7,2,20);
insert into paths values (12,5,4,40);
insert into paths values (13,5,7,40);
Suppose the source = ISL and target = QT, their are various paths from ISL to QT:
Ord# Relative Path Cost
==== ================================= =================
1. ISL -> MUL -> QT 50
2. ISL -> HYD -> KHI -> QT 60
3. ISL -> QT 80
4. ISL -> HYD -> MUL -> QT 80
5. ISL -> HYD to KHI -> MUL -> QT 100
This gives us all possible paths sorted by cost.
Any hint or help will be highly appreciated.
Thanks in advance and best regards
Bilal

Color variation between two identical illustrator documents???

I am trying to copy an object from one Illustrator document into another Illustrator document but it keeps changing the color and adding a small stroke around the object. I can seem to figure out why it would be doing this???? I have check the color modes on both and they are both in CMYK.
Any thoughts???

Have you measured the colour?
Do you get different readings or is it just a a contrast thing? (The "stroke" might be just an anti-aliasing artifact.)
Sometimes your eyes can fool you.
In this example the little grey inside squares are exactly the same colour but your eyes tell you that the left hand one is blueish and the right hand one is yellowish.

User Profile number mismatch between two identical farms

I've created a secondary High Availability farm with, I believe, all of the same User Profile settings as the primary farm.
The primary shows:
Number of User Profiles 3,428
Secondary:
Number of User Profiles 3,363
Any recommendations on how to compare these results in a way that will establish why there is a discrepancy?
Thanks,
Scott

How long has the primary farm been running? My first thought is you may have some orphaned (old) profiles from users who no longer have accounts and maybe haven't been completed cleaned up.
Another thought: Are you syncing the same OUs in both farms?
Do you have multiple authentication stores (Active Directory and a custom FBA provider for example)?
