Version change info:

Version Updated Date Major Changes
HANADumpAnalyzer 1.0.201906061800 2019-06-06

1. Starting from SAP HANA 2.0 SPS 03, a new workload auto-tuning feature is introduced: in case of high load to the system, MAX_CONCURRRENCY parameter is automatically adjusted to shrink the capacity for OLAP load. As a result, the system will distribute more capacity to the OLTP transactions and the OLTP load are more preferred to be processed. If the above situation happens and MAX_CONCURRENCY is reduced to a rather small value, the previous version can provide wrong conclusion that HANA is overloaded because wrong configuration of MAX_CONCURRENCY. This version fixed this wrong conclusion and enhanced the workload analyzer to analyze HANA workload even if the workload auto-tuning feature is triggered.

2. Fixed bugs for indexhandle state graph, dotGraph, blocked transactions graph are not working correctly if they are big.

3. Starting with SAP HANA 2.0 SPS 04, there is a format change for the system views on [STATISTICS] section in the HANA runtime dump. Due to this change, earlier version of SAP HANA dump analyzer are not working correctly with error message “There is a problem to analyze this dump”. This new version fixed this issue and supports HANA runtime dumps from HANA version lower than HANA 2.0 SPS 04 and above.
