H2: JdbcSQLException: This CLOB or BLOB reference timed out

Upon using h2 in java (calling getBytes function) I'm getting the following error. Google didn't get me anywhere. I wonder if anyone has clues what's going on.

This error message can occur if you have a long running transaction for instance. You can increase the timeout by setting the LOB_TIMEOUT property on the database connection.
Database setting LOB_TIMEOUT (default: 300000, which means 5 minutes).
The number of milliseconds a temporary LOB reference is kept until it times out. After the timeout, the LOB is no longer accessible using this reference.

Error Creating Table java.sql.SQLException: JDBC LLR, table verify failed for table 'QQE4D.WL_LLR_I0_LTAPP107', failed to create table

I have an issue with weblogic and jdbc configuration. We are using weblogic 12c and jdbc to connect to oracle.
I am getting an error while creating a table with name WL_LLR_ADMINSERVER.
Below is the error
Failing reason: javax.transaction.SystemException: Failed to call registerLoggingResourceTransactions() weblogic.transaction.loggingresource.LoggingResourceException: weblogic.transaction.loggingresource.LoggingResourceException: java.sql.SQLException: JDBC LLR, table verify failed for table 'QQE4D.WL_LLR_I0_LTAPP107', failed to create table javax.transaction.SystemException: Failed to call registerLoggingResourceTransactions() weblogic.transaction.loggingresource.LoggingResourceException: weblogic.transaction.loggingresource.LoggingResourceException: java.sql.SQLException: JDBC LLR, table verify failed for table 'QQE4D.WL_LLR_I0_LTAPP107', failed to create table.
The query being fired to create the table is
JDBC loggging last resource (LLR) connection pool KernelDataSource did not find its table and is creating a new one using the following SQL:
CREATE TABLE QQE4D.WL_LLR_I0_LTAPP107 (XIDSTR VARCHAR(40) NOT NULL PRIMARY KEY, POOLNAMESTR VARCHAR(64), RECORDSTR VARCHAR(1000))>
The code congigured for the datasource in xml file is
<jdbc-system-resource>
<name>KernelDataSource</name>
<target>cluster</target>
<descriptor-file-name>jdbc/KernelDataSource-int-jdbc.xml</descriptor-file-name>
The datasource xml contains the connection url, driver name, username and the encrypted password details.
I have seen some errors like below but for my case i am not able to create the table itself so i could find the exact solution for my issue.
weblogic.transaction.loggingresource.LoggingResourceException: java.sql.SQLException: JDBC LLR, table verify failed for table 'DEV_SOAINFRA.WL_LLR_ADMINSERVER', row 'JDBC LLR Domain//Server' record had unexpected value 'osb_domain//AdminServer' expected 'osb_cluster_domain//AdminServer' ONLY the original domain and server that creates an LLR table may access it.
Even i don't see these datasources linked to this server in weblogic console as well under monitoring tab. I guess we can see once this issue gets resolved.
I have seen that the atable name should not exceed 18 characters and my table WL_LLR_SERVERNAME is WL_LLR_I0_LTAPP107 which is exactly 18 characters and this is also not an issue.
Can someone please help me in this regard.

The connection looks like this:
connection = DriverManager.getConnection(
"jdbc:jtds:sybase://127.0.0.1:2631/serverName", "DBA",
"password");
I had heard that this may ocurre do to the driver, but i get the same error when I am using jconn3.

Embeded Firebird Database and Hibernate

I am trying to use the Firebird embeded DB together with Hibernate, but I get the following error when trying to create the database:
Caused by: org.firebirdsql.jdbc.FBSQLException: GDS Exception. 335544344. I/O error during "CreateFile (open)" operation for file "D:\DB\FIREBIRD.FDB"

What I have done until now:
I've set the hibernate configuration.
Driver = "org.firebirdsql.jdbc.FBDriver",
Dialect = "org.hibernate.dialect.FirebirdDialect",
Url = "jdbc:firebirdsql:embedded:D:\DB\FIREBIRD.FDB",
I have added the jaybird-full jar to my classpath.
I have added jaybird22.dll, fbembed.dll (the whole folder) to my path.
The dlls seem to be loaded since if I delete the dlls I get and exception telling me that jaybird22.dll cannot be found.
Any idea what could be wrong ?

It seems the step I was missing was creating the database file manually:
FBManager manager = new FBManager(GDSType.getType("EMBEDDED"));
manager.start();
manager.createDatabase(myDbFile, username, password);
manager.stop();

could not get database metadata java.sql.SQLException:

I am using hibernate sharedFactory for database updation.
When am trying to do one updation am getting the following errors on log:
2011-09-01 16:17:50,406 ERROR (org.hibernate.tool.hbm2ddl.SchemaUpdate:134:execute) - could not get database metadata
java.sql.SQLException: Connections could not be acquired from the underlying database!
2011-09-01 16:32:05,734 ERROR (org.hibernate.tool.hbm2ddl.SchemaUpdate:165:execute) - could not complete schema update
java.sql.SQLException: Connections could not be acquired from the underlying database!
And the exception is exactly throwing on this line of code..
sessionFactoryShard = shardedConfig.buildShardedSessionFactory();
Can anyone tell why this error occurs?
