Corrupt Piggydb database

Reported by Sefan Sultanov | March 17th, 2017 @ 03:13 PM

Hi,
My PiggyDB server refuses to start with the corrupt Piggydb file. The error message is as follows:
ERROR 2017/03/17 15:05:20 javax.servlet.UnavailableException: org.springframework.jdbc.CannotGetJdbcConnectionException: Could not get JDBC Connection; nested exception is org.h2.jdbc.JdbcSQLException: File corrupted while reading record: "[8] stream data key:29 pos:11 remaining:0". Possible solution: use the recovery tool [90030-145]

Unfortunately there is no way I could recover the database as no backups were made. Lame. Please help!
I tried to recreate the piggydb folder and it works, but as soon as I replace the h2.db file with the corrupt one, it refuses to work.

    Hi Sefan,

    You can probably recover your data by using the recovery tool provided by H2 database.

    http://www.h2database.com/html/advanced.html#using_recover_tool

    The followings are the steps to recover your data:

    1) First, stop your piggydb server.

    2) Copy the files named like h2*.jar from webapp/WEB-INF/lib to your database directory (~/piggydb/ by default).

    3) Execute the command below in the database directory:

     java -cp h2*.jar org.h2.tools.Recover

    This command will produce a file named piggydb.data.sql by which you can restore your database.

    4) Delete all the lines that contain CJKFullText from piggydb.data.sql because they will cause an error when executing.

    5) Move all the old database files (*.db) to another place for backup.

    6) Execute the commands below:

    java -cp h2*.jar org.h2.tools.RunScript -url jdbc:h2:~/piggydb/piggydb -user sa2 -script piggydb.data.sql -showResults

    7) Start your piggydb and check the content.

    I hope this works for you.
