Re: H2, LibreOffice and Java

2013-05-30 Thread Jorge Alberch
Hi Noel,

No, I don't think so. I'm checking the LibreOffice Base - Connections 
settings and I have the Connection pooling enabled unchecked... however, 
since you mention it... would it be a good idea to have checked instead? 
But then which driver would I select? the JDBCDriver?

Note: regarding H2 itself, on the Windows OS, cmd screen I initiate the H2 
Server by running a script with the following:
java -cp h2*.jar org.h2.tools.Server -tcpAllowOthers -webAllowOthers

Thanks again,
Jorge

 You could try using Wireshark or Microsoft Network Monitor to capture 
 the connection, that might provide some more information. 

 You aren't by any chance using some kind of Connection Pool are you? 
 Some of those have timeout logic in them to kill off stale connections, 
 and that might be accidentally triggering.

H2, LibreOffice and Java

2013-05-26 Thread Jorge Alberch
@Dear Thomas,

First and foremost: A million heartfelt thanks for your impressive work on 
H2. I've been using it for the last 2 years to run a nice little concurrent 
user (server mode) LibreOffice database.

@All,

However over the last month the database appears to disconnect itself. To 
be specific: I'll leave the LibreOffice database open, then come back to 
after 15 minutes, scroll down some records and the database will freeze 
(note: this did not happen before). I have fixed this by inserting 
AUTO_RECONNECT=TRUE in the LibreOffice Base Database Properties - 
Datasource URL.

Now the database will reconnect automatically, however there'll be a short 
period of waiting during this time which is annoying... I also worry about 
the other users which are non-technical people and consequently finicky.

Note: on the Windows OS, cmd screen I initiate the H2 Server by running a 
script with the following:
java -cp h2*.jar org.h2.tools.Server -tcpAllowOthers -webAllowOthers

Question: Is there a way to keep the database open, or a way to avoid 
this waiting time for the LibreOffice database to Auto-Reconnect?

More notes: The database was running perfectly for 2 years... I was running 
the H2 database server mode on an exclusively dedicated old desktop box. 
Only changes have been the upgrade of the Java version which I think 
(though this is simply my guess and I could be wrong) that the Java upgrade 
is to blame.

Any ideas?


Thanks in advance,
Jorge Alberch
