Each HyperSQL database is called a catalog. Main classes for the Hsqldb tools org. Throwable while attempting to get a new connection: This method of access also uses the HTTP protocol. But if a second connection is made to an open database, using a path and name that differs only in case, then the connection is made to the existing open database. The public name hides the file names from users. The first time in-process connection is made to a database, some general data structures are initialised and a few helper threads are started.

Unable to recover XA Datasource state after exception
Connection object also has some methods for transaction control. A connection should be reused as much as possible and closed only when it is not going to be used again for a long while.
In case of an exception the XA Datasource looses track of its state with the following exception. They are briefly discussed below.
I’ve run into the same problem. Sometimes its helpful to use a search engine to find reports of the same problem. A command similar to those used for running tools and described above is used for running the server. These files should not be deleted by the user. Here is my XA Datasource configuration.
Standard compliance is the most unique characteristic of HyperSQL. In this situation, connections to a catalog are usually made in-processor using a separate Server. This method of access is used when the computer hosting the hsqlb server is restricted to the HTTP protocol.
The database engine runs in a JVM and opens one or more in-process catalogs. The Servlet mode can serve multiple databases. This measure is necessary because in Windows the two paths are equivalent.
Could not find accessor on XADataSource: Therefore we do not consider it to be in working order yet. This guide covers the database engine features, SQL hssldb and different modes of operation.
The exception is the default SA user, which is not case-sensitive. Can you please provide me the issue number, so hzqldb we can keep track of this? Connecting to a Database Server.
A common example is connection to the default port used hsqlsb the hsql: HyperSQL can provide database access within the user’s application process, within an application server, or as a separate server process. In general, JDBC is used for all access to databases. PreparedStatement object is created, the engine keeps the compiled Hsqlcb statement for reuse, until the java.
Correct Answers – 4 points. This method of access also uses the HTTP protocol. The SQL statement usually contains parameters, which can be set to new values before each reuse. Changes to the structure of the database, such as dropping or modifying populated CACHED tables or indexes also create large amounts of unused file space that can be reclaimed using this command.
It is used when a servlet engine or application server such as Tomcat or Resin provides access to the database. Until there is an exception everything works fine. When using relative paths, these paths will be taken relative to the directory in which the shell command to start the Java Virtual Machine was executed. They do not provide a web front end to the database.
