Grails accessing H2 TCP server hangs

Question

I have a Grails app which works fine when using the default embedded H2 database. Now I'd need to run some tests where I need more integrated environment, so I thought of using H2 in server mode for this and making my other apps access the same DB.

I start the H2 server from command line and get tcp://192.168.56.1:9092 for the server URL. I've set it in Grails datasource as jdbc:h2:tcp://localhost:9092/~/devDb;IFEXISTS=TRUE.

Once I start the Grails app, it simply hangs. The log file is empty.

I've tried the URL with external DB client and can verify that the server is working.
When server is started from the command line with command java -cp h2*.jar org.h2.tools.Server. Also tried with java -jar h2*.jar -tcp -tcpAllowOthers when the IP address changes, but the effects are the same: Connection OK from SQL client, hangs with Grails.

The IP address 192.168.56.1 equals localhost, just for clasrification. I've tried with both in Grails, and the results are the same. Also, both work with external client.

Version information:

 - **Grails: 2.3.6**
 - **Groovy: 2.2.2**
 - **Java: 1.6.0_45**
 - **H2: 1.4.180**

UPDATE

OK. It doesn't 'just hang', the timeout simply is quite long. I left the program running in the background and forgot it (previously I had killed the process), left the computer. Once I got back hours later, I got a long stacktrace of Spring bean creation errors waiting for me. I think the 'beef' is what is pasted below.

UPDATE 2

Below are the trace logging suggested by Thomas in his comment.

This looks like a network problem. Could you enable debug logging by using the database URL `jdbc:h2:tcp://localhost:9092/~/devDb;IFEXISTS=TRUE;TRACE_LEVEL_SYSTEM_OUT=3` and then check for exceptions in system out? Or use `TRACE_LEVEL_FILE=3` but then you will need to find the `*.trace.db` file (it should be in a subdirectory of the current working directory, sometimes it is hard to find). — Thomas Mueller, Jul 18 '14 at 12:49
@Thomas, I see 10 *trace.db files, files 0 to 8 seem to contain connection details, last one starts with the same lines. Trace file 9 pasted in the updated question. — kaskelotti, Jul 18 '14 at 14:22

"unexpected status 16777216 / 16842752" (0x1000000 / 0x1010000):

It could be incompatible client and server versions of H2. Even thought the client and the server negotiate which transport protocol version to use, so in theory this should not be a problem. So that would be a bug in the server or client implementation. According to the error code, the client is version 1.3.173, and the server is version 1.4.180 as you wrote. Could you ensure you use the same version for both client and server?

It was indeed this problem for me. – Jus12 Jun 20 '16 at 12:07 — Jus12, Jun 20 '16 at 12:07

I've problem: Connection is broken: "unexpected status 16843008" when try to refresh h2 from JetBrains IDEA Database, connected by tcp: jdbc:h2:tcp://localhost:9092/~/dbname, h2.version=1.4.190

@Bean(initMethod = "start", destroyMethod = "stop")
public Server h2Server() throws SQLException {
    return Server.createTcpServer("-tcp", "-tcpAllowOthers", "-tcpPort", "9092");
}

Problem solved only when downgrade h2 version:

    <dependency>
        <groupId>com.h2database</groupId>
        <artifactId>h2</artifactId>
        <version>1.3.176</version>
    </dependency>

Be sure to use the same h2 driver version at application and client (ex. IDEA Database) side.

It also work for InMemory (for spring boot server: spring.datasource.url=jdbc:h2:mem:dbname and for tcp client: tcp://localhost:9092/mem:dbname)

See. Connecting to H2 server from DbVisualizer

@Stephane I'm not shure, that solution is actual... But all h2 version could be taken from central Maven repo: https://search.maven.org/artifact/com.h2database/h2 — Grigory Kislin, Dec 06 '19 at 19:27
