# ((Qora2)) - Qortal Project - Official Repo To use: - Use maven to fetch dependencies. - Build project. - Build v1feeder.jar as a fatjar using src/v1feeder.java as the main class - Fire up an old-gen Qora node. - Use ```v1feeder.jar``` to migrate old Qora blocks to DB: ```java -jar v1feeder.jar qora-v1-node-ip``` You should now be able to run all the JUnit tests. You can also examine the migrated database using [HSQLDB's "sqltool"](http://www.hsqldb.org/doc/2.0/util-guide/sqltool-chapt.html). 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 where Maven downloaded hsqldb, typically ```${HOME}/.m2/repository/org/hsqldb/hsqldb/2.4.0/hsqldb-2.4.0.jar```, but for now ```lib/org/hsqldb/hsqldb/r5836/hsqldb-r5836.jar``` ```${SQLTOOL_JAR}``` contains pathname to where Maven downloaded sqltool, typically ```${HOME}/.m2/repository/org/hsqldb/sqltool/2.4.1/sqltool-2.4.1.jar``` ```${SQLTOOL_RC}``` contains pathname to a text file describing Qora2 database, e.g. ```${HOME}/.sqltool.rc```, with contents like: ``` urlid qora url jdbc:hsqldb:file:db/qora username SA password urlid qora-test url jdbc:hsqldb:file:db/test username SA password ``` You could change the line ```url jdbc:hsqldb:file:db/test``` to use a full pathname for easier use. Another idea is to assign a shell alias in your ```.bashrc``` like: ``` export HSQLDB_JAR=${HOME}/.m2/repository/org/hsqldb/hsqldb/2.4.0/hsqldb-2.4.0.jar export SQLTOOL_JAR=${HOME}/.m2/repository/org/hsqldb/sqltool/2.4.1/sqltool-2.4.1.jar alias sqltool='rlwrap java -cp ${HSQLDB_JAR}:${SQLTOOL_JAR} org.hsqldb.cmdline.SqlTool --rcFile=${SQLTOOL_RC}' ``` So you can simply type: ```sqltool qora-test``` Don't forget to use ```SHUTDOWN;``` before exiting sqltool so that database files are closed cleanly.
