Overheads comparison

[Former Member]

Is there a comparative of the overheads required for each adapter, all other parameters remaining the same?

I am looking for a comparative of the following:

iDoc, SOAP, RFC, File, ABAP Proxy

Thanks in advance

see performance monitoring

You use performance monitoring to display statistical data on the performance of message processing. The data comes from the Integration Server (IS) or the Process Monitoring Infrastructure (PMI).

The central tool for performance monitoring is the Runtime Workbench, which you call from the SAP Exchange Infrastructure start page.

for detail see

Hi fatima,

I do not have all above adapters used in my instance. Hence, I need help in getting this info. But the link is informative..thanks!

A comparison between different adapters connecting different system doesn't make much sense. If its the same system, like ECC, then comparison between Idoc/RFC/Abap Proxy makes sense. Then there are various factors based on which the strategic decision has to be taken. For other systems, say file system, even if it is slower than say XYZ adapter and you have to use file adapter for your business case, you have to use file adapter.

Thanks all for your response.

@ Prateek

I need to know what are the overheads in case all other parameters are constant (eg. source/target/payload etc)....I have mentioned this in my original Q.

@ Shabarish

The link was informative. But it has not solved my query. It does not mention anything about te overheads required. I need to know what would be the overheads (in bytes/kb/mb) for using each adapter

@ Ravi / Krish

Didnt want to confuse ya guys with irrelevant info but since you've asked here it is:

My client has POSs (point of sale) retail outlets at multiple locations. They use a non-SAP application for the POSs. This app sends iDocs to SAP (at their main office) on an hourly basis. In return SAP also sends hourly inventory updates to each POS.

Now they wanna make this online. So there...

Now we need to know that if instead of iDocs we use, for example, say webServices, how will the performance be.

Since all other parameters (source/target/bandwidth/payload) is gonna remain the same, it actually narrows down to the overheads incurred by each type of adapter.

They really dont care whether we use idocs or webservices or BAPIs as long as they get to see the data in real time. Of course, in XI there is no such thing as realtime, so if we are gonna poll, say every 5 seconds, is it gonna workout...thats what we need to know.

We really do not wanna give them webservices if the xml overheads swamp out their bandwidth right. If the iDocs themselves have a minimal overhead, we can always just reduce the timeframe...but then again, if.

Hope this clarifies your query

Hi

If that is u r case you can go with "WebService" as it woulb be realtime "Synchronous" sending you status.

For WebService there is no polling such kind , when Request is sent Response is back.

Polling is for File Adapter / jdbc adapter.

Hi srini,

Thanks for the update...can you tell me what would the overhead be in this case?

Thanks

Hi

WebService would be realtime when compared to IDOC

Hi Con,

Each of these adapters are meant for a specfic purpose and they cannot be compared to one another.

Why do you need this information?

Hi,

Can you elaborate your requirement.

Do you want the performance of these adapters.
