Last modified by michaely on 2021/09/10 22:40

In some cases the internal database can become corrupt and prevent use of the iSymphony application. Users will normally see errors like the following when accessing the panel:

Information

The error may vary slightly from the example below.

org.apache.ibatis.exceptions.PersistenceException:
### Error querying database.  Cause: org.h2.jdbc.JdbcSQLException: General error: "java.lang.RuntimeException: rowcount remaining=5 SYS" [50000-169]
### The error may exist in com/xmlnamespace/panel/server/core/pbx/callhistory/CallHistoryMapper.xml
### The error may involve com.xmlnamespace.panel.server.core.pbx.callhistory.CallHistoryMapper.getByExtension
### The error occurred while executing a query
### Cause: org.h2.jdbc.JdbcSQLException: General error: "java.lang.RuntimeException: rowcount remaining=5 SYS" [50000-169]

Repair Process

In order to recover your data, you will need to run a repair process on the database. The repair process is outlined below:

  1. Stop the iSymphony server. See Starting And Stopping The iSymphony Server.

  2. Create a temporary directory to perform the recovery.

    mkdir isdbrecovery
    cd isdbrecovery
    Warning

    Do not create this directory anywhere inside the /opt/isymphony3 directory.

  3. Copy the h2 database jar into the recovery directory:

    cp /opt/isymphony3/server/modules/framework/shared/org.h2_1.3.169.jar .

  4. Copy the database file into the recovery directory:

    cp /opt/isymphony3/server/conf/servers/default/isymphony.h2.db .
    Information

    If you have Core Servers other than default you will need to replace default with the slug of the core server you are repairing the database for.

  5. Run the following command to export the database to an sql file:

    java -cp org.h2_1.3.169.jar org.h2.tools.Recover

  6. Create a sub directory to hold the old database:

    mkdir old
    mv isymphony.h2.db ./old

  7. Run the following command to create a new database from the sql file:

    java -cp org.h2_1.3.169.jar org.h2.tools.RunScript -url "jdbc:h2:./isymphony" -user admin -password admin -script isymphony.h2.sql

  8. Move the new database into place:

    mv isymphony.h2.db /opt/isymphony3/server/conf/servers/default/
    Information

    If you have Core Servers other than default you will need to replace default with the slug of the core server you are repairing the database for.

  9. Ensure that the new h2.db file has the same ownership and permissions as the original file.
