We fixed the previous issue, and your scenario is sufficiently different that it's probably a separate bug. <div><br></div><div>I wonder whether the multi-threaded nature of your application is causing this. If the list of columns in a star is changing, say because one connection is using a star for a query while another one is building a schema and adding columns to the same star, then that might explain it. I don't have the solution to the bug, but hopefully these remarks would give an engineer a clue where to look.</div><div><br></div><div>Julian</div><div><br><div><div>On Nov 15, 2013, at 3:43 AM, Hilario Fernandes <<a href="mailto:hilario.fernandes@cortex-intelligence.com">hilario.fernandes@cortex-intelligence.com</a>> wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><div dir="ltr">So, i've been trying to isolate this issue and it has not been easy, but finally i've managed to get one run where i got the erros in a log i could use to present here. One thing to point out, this is not consistent. The sequence of queries that gave the error might not give it if i run it again on the same conditions with no change in the data. This is what is making it so hard to figure what's causing it.<div>
<br></div><div>The project i'm working is built uppon grails framework, there is a service in it that holds the olapConnection to run the queries. These are the startup parameters:</div><div><br></div><div><div>def connectionProperties = '' << 'jdbc:mondrian:'</div>
<div>connectionProperties << "Jdbc="jdbc:monetdb://host:50000/database;"</div><div>connectionProperties << "JdbcUser=username;"</div><div>connectionProperties << "JdbcPassword=password;"</div>
<div>connectionProperties << "JdbcDrivers=nl.cwi.monetdb.jdbc.MonetDriver;"</div><div>connectionProperties << "UseContentChecksum=true;"</div><div>connectionProperties << "CatalogContent=<Schema name=\"CUBES\"></Schema>"</div>

</div></div><div><br></div><div><br></div><div>The cube schema is generated per analysis so we add it before the query and remove it after its completed ("INFO mondrian.MondrianBridge CURRENT CUBES:[]" in the log indicates the cubes in the global schema at that time). This is the code we use for that:</div>
<div><br></div><div><div>RolapSchema schema = getServerSchema(olapConnection)</div><div>schema.createCube(xml)<br></div><div>...</div><div>schema.removeCube(cubeId)</div></div><div><div><br></div><div><br></div></div><div>
Query execution is done with this code:</div><div><br></div><div>OlapStatement statement = olapConnection.createStatement()<br></div><div>statement.executeOlapQuery(query)<br></div><div><br></div><div><br></div><div>As for the log, i've added it here so the email is shorter: <a href="http://pastebin.com/Y7Z0Hi0b">http://pastebin.com/Y7Z0Hi0b</a></div>
