Hi,
We were getting database crashes when we were using our database with read/write mode and using the default sql_optimizer settings. We decided to run our database in read-only mode and also has changed the sql_optimizer setting to sequential_pipe.
With new settings we don't see any crashes but have started to see error messages in the log files similar to the following lines.
2014-04-25 08:21:52 ERR db1[14554]: #mvc_bind_schema schema1 2014-04-25 08:21:52 ERR db1[14554]: #mvc_bind_table schema1.table1 2014-04-25 08:21:52 ERR db1[14554]: #mvc_bind_column table1.col1 2014-04-25 08:21:52 ERR db1[14554]: #mvc_rollback 2014-04-25 08:21:52 ERR db1[14554]: #mvc_rollback done 2014-04-25 08:21:52 ERR db1[14554]: #mvc_commit 2014-04-25 08:21:52 ERR db1[14554]: #mvc_commit done
My question is there a procedure to follow when we change sql-optimizer settings? I assume MonetDB has some history of the past and because of the change of the sql_optimizer settings the bits in the history causing these error messages but i would not be surprised if this is completely wrong.
