Centera Universal Access Question
Hi,
Sorry to ask this question here but I have been unable to find anyone in EMC to speak to about CUA.
We have a customer that uses Centera and have existing content written to it via an unknown application.
The customer wishes to use a full text index product to index the content already stored in Centera. The full text index software is not Centera aware.
If CUA is installed, would this allow the full text indexer to read (and therefore index) the existing content? (i.e. can CUA make Centera storage "look" like a filesystem for content that has been written by a different application.
I suspect not, but I just need confirmation on this.
Thank you in advance for any advice,
Craig

CUA is used to present shares in the network and files written to these shares are then migrated to Centera.
CUA will not do the reverse for you
If you don't have the application anymore you would need to investigate a couple of days to analyse the data structure and read the objects back into a filesystem. There the files could be indexed and then using an HSM software be migrated back to Centera.
I think this would take 10 to 15 days of effort to develop a program that could do this for your customer. Provided they are able and willing to get some sample objects to us.
If you still have your application use it to give access to the full text index product.
We did a similar thing for a customer who wanted to be able to retrieve his archived information without the archive software. For this customer we developed a software that writes back the archived information into a filesystem using the SAP document classes and SAP object identifiers to create the directory structure and file names.
Best regards, Holger

Thank you for your answer and suggestions. We now have extra detail from the customer, they may do as you suggested and export the content previously stored then re-import it using CUA.
I have been told that re-importing content will not increase the storage used on the Centera box as it will recognize the re-imported content as already being stored.
Anyway thank you again for answering this question ...

That's good news. Single Instancing will only work for objects bigger than 256kB. Have a look at storage strategy (using show features) to find your limit.
For smaller objects you will need the capacity again.
