Import not Copy:-

While deploying a mapping from Dev to QA or QA to Prod,always try to import first.
If you face any error in importing then copy the mapping from source to target environment.
The reason for that is while copying the sources and targets gets copied as NON-SHORTCUT whereas they should have been copied as shortcut.

There might be possibility that in your project you keep all your source/target/transformation/mapplets etc into a shared folder and you are using those components in different different mappings.

In copying they will be copied not as shortcut to that folder but a separate copy which definitely you dont want.

Set relational connection in UTF8 by default
This will avoid much data corruption issues.

Relational connection changes required?-Replace if possible

You may need somtime to fix some passwords/userid/codepage/parrallism in relational connection.
Create a new with your required changes.
Replace the old with this new.
Delete the new.
This will help you avoid validating a no of sessions which might be using the old relational connection.

I got the solution from ITTOOLBOX.
docking problems with powercenter designer

And it is:-
1. close all Informatica instances like Designer , Workflow manager and monitor
2. backup the registry
3. go to HKEY_CURRENT_USER
4. go to SOFTWARE --> Informatica --> POWERMART CLIENT TOOLS --> (whichever version you are using) my case 7.1 -->Designer/Workflow Monitor/WFManager --> Toolbars 7.1
5. rename the folder Tolbars 7.1 to anything like toolbars 7.1_old
6. save and exit the registry editor
7. Restart Informatica Designer/WFManager/WFMonitor

I got this article from other blog.From Fake IPL Player - In some comments
And I could not but laughing reading that.Its an amazing description of BANGALEES and veryy veryy true.
Very beutifully written.

A is for Awpheesh (as in Office). This is where the average Kolkakatan goes and spends a day hard at work. And if he works for the 'Vest Bengal Gawrment' he will arrive at 10, wipe his forehead till 11, have a tea break at 12, throw around a few files at 12.30, break for lunch at 1, smoke the 7th unfiltered cigarette at 2, break for 5th cup of tea at 3, sleep sitting down at 4 and go home at 4:30. It's a hard life!

B is for Bhision. For some reason many Bengalis don't have good bhision. In fact in Kolkata most people are wearing spectacles all the time....Bhishon Bhalo and Bibhotso.... though means opposite ...used for same situations.. .depending on the Beauty of fairer sex...are close ...almost in a tie for second spot....

C is for Chappell. Currently, this is the Bengali word for the Devil, for the worst form of evil. In the night mothers put their kids to sleep saying, 'Na ghumoley ebar Chappell eshey dhorey niye jabe.'

D is for Debashish or any other name starting with Deb. By an ancient law every fourth Bengali Child has to be named Debashish. So you have a Debashish everywhere and trying to get creative they are also called Deb, Debu, Deba with variations like Debopriyo, Deboprotim, Debojyoti, etc. thrown in at times....as creations of God himself !!

E is for Eeesh. This is a very common Bengali exclamation made famous by Aishwarya Rai in the movie Devdas. It is estimated that on an average a Bengali, especially Bengali women, use eeesh 10,089 times every year. 'Ei Morechhey' is a close second to Eeesh.

F is for Feeesh. These are creatures that swim in rivers and seas and are a favourite food of the Bengalis. Despite the fact that a fish market has such strong smells, with one sniff a Bengali knows if a fish is all right. If not, he will say 'eeesh what feeesh is theesh!'

G is for Good name. Every Bengali boy will have a good name like Debashish or Deboprotim and a pet name like Motka, Bhombol, Thobla, etc. While every Bengali girl will have pet names like Tia, Tuktuki, Mishti, Khuku, et cetera.

H is for Harmonium. This Bengali equivalent of a rock guitar. Take four Bengalis and a Harmonium and you have the successors to The Bheatles!

I is for Ileesh. This is a feeesh with 10,987 bones which would kill any ordinary person, but which the Bengalis eat with releeesh!

J is for Jhola. No selfrespecting Bengali is complete without his Jhola. It is a shapeless cloth bag where he keeps all his belongings and he fits an amazing number of things in. Even as you read this there are two million jholas bobbling around Kolkata, and they all look exactly the same! Note that 'Jhol'with mysterious condiments.. . as in Maachher Jhol is a close second. Jhaamela and Jachhetai are distant 3rd and 4th

K is for Kee Kaando! It used to be the favourite Bengali exclamation till eeesh took over because of Aishwarya Rai.Kee mushkil is a close second.

L is for Lungi, the dress for all occasions. People in Kolkata manage to play football and cricket wearing it not to mention the daily trip in the morning to the local bajaar. Now there is talk of a lungi expedition to Mt Everest.

M is for Minibaas. These are dangerous half buses whose antics would effortlessly frighten the living daylights out of all James Bond stuntmen as well as Formula 1 race car drivers.

N is for Nangto. This is the Bengali word for Naked. It is the most interesting naked word in any language!

O is for Oil. The Bengalis believe that a touch of mustard oil will cure anything from cold (oil in the nose), to earache (oil in the ear), to cough (oil on the throat) to piles (oil you know where!).

P is for Phootball. This is always a phavourite phassion of the Kolkattan. Every Bengali is born an expert in this game. The two biggest clubs there are MOHUNBAGAN and East Bengal and when they play the city comes to a stop.

Q is for Koshchen (question) as in "Mamatadi koshchens Cheap Ministaar in Writaars Buiding."

R is for Robi Thakur. Many many years ago Rabindranath got the Nobel Prize. This has given the right to all Bengalis no matter where they are to frame their acceptance speeches as if they were directly related to the great poet and walk with their head held high. This also gives Bengalis the birthright to look down at Delhi and Mumbai and of course 'all non-Bengawlees'! Note that 'Rawshogolla' comes a close second!

S is for Shourav. Now that they finally produced a genuine cricketer, that too a captain, Bengalis think that he should be allowed to play until he is 70 years old.

T is for Trams. Hundred years later there are still trams in Kolkata. Of course if you are in a hurry it's faster to walk....Trams are still existing in Paris too.......you see !

U is for Aambrela. When a Bengali baby is born he is handed one.

V is for Bhaayolence. Bengalis are the most non-violent violent people around. When an accident happens they will fold up their sleeves, shout and scream and curse and abuse, "Chherey De Bolchhi" but the last time someone actually hit someone was in 1939.

W is for Water. For three months of the year the city is underwater and every year for the last 200 years the authorities are taken by surprise by this!

X is for X'mas. It's very big in Kolkata, with Park Street fully lit up and all Bengalis agreeing that they must eat cake that day.

Y is for Yesshtaarday. Which is always better than today for a Bengali (see R for Robi Thakur)?. It is also for Jubraj Shingh and Joga.

Z is for Jebra, Joo, and Jipper.
