File / Message sizes

[Former Member]

All,

we are having a scenario where a file is read into a single message. The size of the file is around 50 MB.

Is this feasible? Will really appreciate if any of you have used similar or larger files in the file adapter .

Thanks.

Hi,

Size of the file is around 50 MB. Is this feasible?

Definetly it is. But when you poll a file of this size perfornance issues crop up. SAP recommends the file size of around 20 MB.

But is that practically feasible to have a file with less than 20 mb in every scenario?

So the soution is if you are using content conversion parameters set Recordsets per Message to some X value. X = no of records near to 20 mb limit.

When the number of recordsets in a document is greater than the number specified, then the adapter creates multiple messages from a document.

Hi KRR,

You can process 50MB size file in File adapter where in content conversion, there is an option 'Recordset per message'.I tried over 100MB file with over 4 lac records.

KRR,

It is recommends that processing of file with size something around 15-20 MB would be great...Its also depends on weather you are going to use BPM...with BPM processing would be too slow...

Check out this blog by Sravya...really really helpful for handling big files..

HI KRR,

20 MB should be the average file size for better performance. Exceeding this limit will certainly have some performance issues and cause memory leaks. If you are using PI(7.0) these issues have been addressed in the adapter configuration where you can specify the file size.

Hey

it depends a lot upon your hardware configuration. in case you are getting any issuea then u may split the file into smaller chunks and then feed it to XI

Thanx
