Performance issues while migrating documents to documentum

Chandrashekhar_Deshmukh

Hi,

I am working on migration project in which  I want to migrate documents from legacy system to documentum.  It is a batch process and I am expecting 5-6 documents should be migrated within 1 Second.  Following are some performance issues I am facing - 

1) It's taking almost more than 2 seconds to save object in repository using IDFSysobject.save() method . Document size varies between 20kb - 1MB max.

my expectation is document should be saved withing 200-300 miliseconds.

2) In another code , I am creating versions of document using IDFCheckoutOperation.checkout() and checkin() methods.  This also taking quite more time almost 1 - 1.5 seconds per version. Example , I am creating a document with 5 versions , so it's almost taking 5-8 seconds to create such document.

Any clue on how can we optimize performance to make faster save and checkin/checkout ? any configuration required at repository level ?

Any help/support will be appritiated.

Regards,

Chandra

You may be able to improve the save performance, depending on your customisations and your code. Some questions to ask yourself:

- From where do you do your setfiles? From a client machine? If yes, try to move them directly to the COntent Server and do it from there.

- Is your DFC code efficient? E.g. do you call save multiple times instead of just one time? Do you run queries more often than needed?

- Any TBO that may slow down the import?

- Do you have many custom databases indexes? Perhaps remove them and recreate them at the end of your migration

- Can High Volume Server help you (e.g. batching, lightweight sysobjects)?

- ...

But you will most definitely need to use multiple threads to achieve the performance that you want.
