Performance Issues when loading a 24000 item Catalogue

[Former Member]

We are try to load a 24000 line catalogue via an XML file, we have laoded it on one system but are unable to load it on another, looking at the various settings there does not seem to be many differences if any. Can anyone suggest why this maybe happening. Also we get a ST22 error log : - "SYSTEMS_NO_ROLL"

Any help would be of great use

Some settings we have checked are : -

ztta/roll_area

2000896

ztta/roll_extension

2000683008

abap/heap_area_total

2000683008

abap/heap_area_dia

2000683008

abap/heap_area_nondia

2000683008

em/initial_size_MB

512

Hi

Which SRM / CCM version, Support packs are you using ?

Seems to be a BASIS Isue. Ask BASIS Team to help you out in this problem.

<b>Please go through this -></b>

This dump happen when the program ends because insufficient memory check the parameters suggested in the shortdump and increase if necesary. There's lots of sap notes try note 353579

Also check the OSS note 828857.

Check for swaps in ST02 and possibly incread the size of ztta/max_memreq_MB

This is coming becasue roll areamemory is not sufficient to handle this kind of load. Transaction ST05 will help you in identifying the bottlenecks.However if the error is coming with standard SAP or is not going away with fine tuning of custom code then you need to increase the values of profile parameters like:

ztta/roll_area, ztta/roll_extension and abap/heap_area_total (it all should be done with proper consideration).

Though I must add that the values given as default values by SAP are sufficient enough. Another option is to reduce the number of entries you are trying to load.

Before making changes to any of the profile paramters mentioned in my previous replycheck the value of this paramter: ztta/max_memreq_MB. This is nothing but OSS note 353579 as suggested by Juan . First increase its value (make it double of exisitng value)and do a check by trying the data load once again. I can't say for sure that changing the value of the paramter ztta/max_memreq_MB alone will fix this issue.

However if this does not work out then make changes to the other three parameters mentioned in my previous mail.

To check the exisiting values go to RZ11 and display the value for each paramter. here you can also read the documentation for each parameter. The documentation will guide you. Also each of these parameters will have maximum value so you will know what maximum value is allowed. I would recommend you to double the existing values for these paramters.Atleast try to increase the values by 50%.

Then you can make the changes in RZ10. For knowing how to make changes in RZ10 check this link:

Do let me know.

Hope this will definitely help.
