Note #1110822 does describe how to reduce the size of aggregates for the new workload collector.
2GB limit is for cluster table system limit to handel import and export workload statistic data from cluster table (SWNCMONI is compressed data in the DB table)
From ST03N can be read aggregats data. if to much instance it can not be callculated and the dump will occure "TSV_TNEW_PAGE_ALLOC_FAILED" -> memory problem because there is not enough space in row memory space :
| o ztta/roll_area | (1.000.000 - 15.000.000) | ||
| | | Classic roll area per user and internal mode | ||
| | | usual amount of roll area per user and internal mode | ||
| | | o ztta/roll_extension | (10.000.000 - 500.000.000) | |
| | | Amount of memory per user in extended memory (EM) | ||
| | | o abap/heap_area_total | (100.000.000 - 1.500.000.000) | |
| | | Amount of memory (malloc) for all users of an application | ||
| | | server. If several background processes are running on | ||
| | | one server, temporary bottlenecks may occur. | ||
| | | Of course, the amount of memory (in bytes) must also be | ||
| | | available on the machine (main memory or file system swap). |
Special case :
| The internal table "{O:118*\CLASS=CL_SWNC_AGG_WEB_SERVER}\DATA=T_AGGREGATES" | ||
| could not be further extended. | ||
| "TSV_TNEW_PAGE_ALLOC_FAILED" " " | ||
| "CL_SWNC_AGG_WEB===============CP" or "CL_SWNC_AGG_WEB===============CM001" | ||
| "CONSTRUCTOR" |
>>>>> t_aggregates = i_t_aggregates.
It is caused by WEB aggragets:
You have to reduce the size of "WEB Server" and "WEB Server Dest" profiles (using "SWNC_COLLECTOR_COMPRESSION")and recompress the data
(using "SWNC_COLLECTOR_RECOMPRESS") afterwards. See SAP Note #1110822 for details and from it the part with VC
At first deactivate a less important part of the aggregate,then start the recompression report and check if the dump still occurs.
Accordint to the note, it only suggest how can be compressed but the choice is individual
Alternative solution note #1578639 you need to run report : 'SWNC_CONFIG_URL' and select the 'URL without handle' option and then save (this is the easier solution) no matter what your system release version is.
Report SWNC_COLLECTOR_COMPRESSION creates the customizing, so every time when you want to change the customizing you have to start the
report.
Report SWNC_COLLECTOR_RECOMPRESS will compress the existing aggregations for the actual Day, Week and Month. Every time when
you change the customizing you have to start the report only one time as a background job.
