Re: stop button doesnt work
Thomas, I just tried a number of combinations with several tabs all running and then I try Stop and it works every time. You say Stop button is disabled. Is the button gray (non clickable) when this occur or is it clickable but nothing happens when it's pressed? Regards Roger

Re: stop button doesnt work
Thomas, I recommend that you try the latest Java 1.6 version. What window manager are you using? Regards Roger

Re: stop button doesnt work
same with Sun JDK 1.6.0_03-b05 and BEA JRockit(R) R27.2.0-131-78843-1.6.0-20070320-1511-linux-ia32

difference: stop is red after tab switch but doesnt work

will test latest jdk in ~2h

Re: stop button doesnt work
One related thing is the semantic of stopping an ongoing SQL processing: When Stop is pressed DbVis requests the JDBC driver to cancel the ongoing SQL. This requires that the JDBC driver is implementing the cancel interface properly. In addition it also means that the JDBC driver should do any necessary clean-up quite fast after cancel is initiated. Some drivers do cancel the ongoing processing but the control is then not at once passed to the client (DbVisualizer) leading to the Stop button still being active and the SQL editor is continuing processing the SQL (well it seem so anyway).

Re: stop button doesnt work
i tried with latest sun jdk, same result. i tried same jdbc driver and jdk (same files) as with dbvis 5.1.1
stopping a query works in dbvis 5.1.1 and not in 6.0.7. stop button is highlighted but has no action.

last try (jdk1.6.0_04 x32, fresh download from sun):

Re: stop button doesnt work
Thomas, What database are you using? Can you please post a screenshot of the SQL Commander with the dead Stop button? A test you may do is to enable debug of DbVis. When you press Stop an entry will be echoed in the debug output. Read more in: http://www.minq.se/products/dbvis/faq.html#6.11 Regards Roger

Re: stop button doesnt work
screenshot attached. db is postgresql 8.1.4 linux x32. as i wrote cancelling statements was ok in dbvis 5.1.1. thats a must have for us

as you can see stop button looks activated. but i cant press it and there is NO debugoutput.

debug output (i pressed stop really often):
20:48:35 [DEBUG Thread-16 H.setCurrentSchema] DbConnection='test' Catalog='null' Schema='public' NewSchema='public'

Re: stop button doesnt work


Roger,

Has this been also addressed for Sybase ASE driver?  We have the same problem, especially when the query is deep into executing state, the app hangs trying to cancel the execution...    ALso, not sure if this is rel;ated, but on some occasions, our DBAs reported that there were still hanging locks from the dbVIS  SPIDs.
