Dear experts,
We have a serious and recurrent problem on SAP HANA SP9 revesion 91. The statisticsserver is down, and sap bw application server which is
connected to hana database loses often the connexion displaying the following dump :
" SAP DBTech JDBC: [3587]: invalid protocol or service shutdown during
distributed query execution: [2613] executor: communication problem
(com.sap.db.jdbc.exceptions.JDBCDriverException: SAP DBTech JDBC:
[3587]: invalid protocol or service shutdown during distributed query
execution: [2613] executor: communication problem)".
At the moment, under sap bw server, when we run the script "startsap
r3", it shows the following error :
"Checking db Database
Database is not available via R3trans
-------------------------------------------
Database db must be started first
"
please find in attachement the log files;
Thanks in advance for your help
Best Regards,
