memory issue for interface

[Former Member]

Hi

we have an interface through which we upload employee attendence data daily after 5 in the evening. If i load data of 1000 employees the interface runs well where as if i run this for 2000 or above the system gets hanged and message says low memory. I checked the system log in SM21 it says TSV_TNEW_PAGE_ALLOC_FAILED.

How can i resolve this issue what tools should i use to analyze the prformance of this interface.

This is Urgent, Pl help

Thanks & Regards,

Hi Anji

I have checked with BASIS guys

They have checked everything the heap size area issue (which is coming in ABAP Dump) is already 2gb which is maximum they can allot in extended memory in SAP .

All the memory parameter they have put it to maximum but still the abap dump of heap size area is coming .Our basis guys are telling us to tune sql statement or internal table which is there in programe , as programme is running fine when it has to display 1000 records only it throws error when the same programme run for 5000 records .

One more thing i would like to add on this interface was running fine till Aug 2007 after that this issue has come up.

Hi Nikhil

Initially there is a file on the appl server which we read through the program check for consistent data then send it to a Ztable. after words this correct data is uploaded using a std report into infotype 2011.

This issue was not there in the past this is comming form last 3 months.

Hi ,

In this case u have to do performance test to ur program , use tcodes ST05,SM50 to check which Coding Blocking needs to be corrected to increase performance of ur report.

orelse Check ST22 of this errors ,aand look for Arrow MArk and paste it here.
