Qora2

To use:

  • Use maven to fetch dependencies.
  • Build project.
  • Fire up an old-gen Qora node.
  • Run src/test/update.java as a JUnit test to build DB structure.
  • Run src/test/migrate.java as a JUnit test to migrate old Qora blocks to DB.

You should now be able to run src/test/load.java and src/test/save.java as JUnit tests demonstrating loading/saving Transactions from/to database.

You can also examine the migrated database using HSQLDB's "sqltool".

It's a good idea to install "rlwrap" (ReadLine wrapper) too as sqltool doesn't support command history/editing!

Typical command line for sqltool would be:

rlwrap java -cp ${HSQLDB_JAR}:${SQLTOOL_JAR} org.hsqldb.cmdline.SqlTool --rcFile=${SQLTOOL_RC} qora

${HSQLDB_JAR} contains pathname to hsqldb-2.4.0.jar, typically ${HOME}/.m2/repository/org/hsqldb/hsqldb/2.4.0/hsqldb-2.4.0.jar

${SQLTOOL_JAR} contains pathname to where you downloaded sqltool-2.2.6.jar

${SQLTOOL_RC} contains pathname to a text file describing Qora2 database, e.g. ${HOME}/.sqltool.rc, with contents like:

urlid qora
url jdbc:hsqldb:file:db/test
username SA
password

You could change the line url jdbc:hsqldb:file:db/test to use a full pathname for easier use.

Another idea is to assign a shell alias in your .bashrc like:

alias sqltool='rlwrap java -cp ${HSQLDB_JAR}:${SQLTOOL_JAR} org.hsqldb.cmdline.SqlTool --rcFile=${SQLTOOL_RC}'

So you can simply type: sqltool qora
