- You observe performance issue, high CPU caused by application SAPLFIS_ACDOCA_BIW in SAP HANA database.
- Collected run time dump (RTE) shows the following in HANA CPU Load Analysis section.
...
Conclusion
System is overloaded by a single query (i.e. over 50% of the threads are running the same query) with SQL: SELECT /* FDA WRITE */ DISTINCT ACDOCA . * FROM ACDOCA , ? AS t_00 (C_0 NVARCHAR(2), C_1 NVARCHAR(4), C_2 NVARCHAR(4), C_3 NVARCHAR(10), C_4 NVARCHAR(6)) WHERE ACDOCA . RCLNT = ? AND ACDOCA . RLDNR = t_00 . C_0 AND ACDOCA . RBUKRS = t_00 . C_1 AND ACDOCA . GJAHR = t_00 . C_2 AND ACDOCA . BELNR = t_00 . C_3 AND ACDOCA . DOCLN = t_00 . C_4 with statement hash: dd12c9e30a0ad46127fe6057cf20dda5
... - Further investigation shows the same execution performing bad when OLAP engine involved. Reference: 3327150 - SQL Statement Collection: "HANA_SQL_StatementHash_DataCollector" report for SAP HANA
