ICM_HTTP_TIMEOUT error

There are two ways of changing this timeout: 

check out note: 824554 and change it in the instance profile

TCODE SXMB_ADM -> Configure Integration server -> change specific identifiers

Set Runtime parameter: HTTP_TIMEOUT

Restart XI after the change

Hardware Impact

The capacity of the hardware resources represents highly significant aspect of the overall performance of the BW system in general. Insufficient resources in any one area can constraint performance capabilities

These include:

• number of CPUs

• speed of CPUs

• memory

• I/O-Controller

• Disk architecture (e.g. RAID)

The hardware sizing should be done according to the recommendations of SAP’s hardware partner. The number of CPUs is dependent on the required number of parallel processes (e.g. upload processes, queries). In the end, better hardware will certainly improve your system performance and should be considered, if all other optimizing activities were not satisfactory.

A reasonable sizing is the prerequisite for satisfactory performance. If your BW system is likely to grow, be sure that the hardware is scalable. We recommend to have a five year growth projection that takes into account a long term near line storage and archiving plan, as well as granularity size goals – for example maintaining two years of detail level data, and five years summary data. You also need to account for your PSA size – Do you delete an old load after the next successful load? Or do you manage PSA at all?

See QuickSizer in SAP Service Marketplace for more details.

The client hardware has also significant impact on the query response time. You can improve rendering time of web applications or BEx Analyzer queries significantly by supplying a better frontend client hardware
