After extract data from R/3 through FM,system became very slow,Urgent ?

Hi gurus:

I constructed a generic function module , and also I constructed an extraction structure. I proved my extractor in transaction RSA3 and when the function module finishes, the function module is called to begin again and to begin again several times until a great amount of repeated data is formed.

My function module is working right, it is extracting all the data, but it don't stops, it begin several times.

At last I found I didn't set conditions to RAISE NO_MORE_DATA, so It runs forever.

Now the problem is , My BW system became very slow ,the harddisk are always very busy,the system read/write the directory SAPMNT all the time.I had delete the datasource ,infocube and even my user id.

and restart the bw service for several times,it's still very slow and have high I/O .

When I checked the backgroud jobs ,I found the job "BI_WRITE_PROT_TO_APPLLOG" RUNS every 5 minutes. Are there some relationship?

best regards

chan

    Check data package setting you have done? howmany idocs are coming/ frequency..?

    How many processes are being consumed?.. check in sm66....

    This can point to some potential issue..

    Have you searched the forum for the job name? I did a quick search and it appears to be a background job that writes events to the application log, and should not be turned off.

    It sounds like you need to have your Basis person take a look into the system to find out why the disk I/O is continuous. They can probably help you find what's causing it. You could also post the question on one of the Basis forums for assistance.

    Below is a message previously posted by Ellora that discusses the job:
