Debugging a corrupted Pentaho Server repository
A corrupted Pentaho Repository will become unresponsive resulting in missing content, inaccessibility, and the following error message that appears in the /pentaho-server/tomcat/logs/catalina.out log file:
ERROR [ConnectionRecoveryManager] could not execute statement, reason:
File corrupted while reading record: "page data leaf table:8 entries:1 parent:49157
keys: offsets:". Possible solution: use the recovery tool [90030-131],
If this error occurs, shut down the Pentaho Server and restore your solution repository from a recent backup.
If you do not have a viable backup, you may be able to minimize data loss by identifying the exact file that is corrupt. Enable debug logging by adding the following XML snippet above the
<root> element in the /WEB-INF/classes/log4j2.xml inside your deployed pentaho.war:
<Logger name="org.pentaho.platform" level=”DEBUG>
Restart the Pentaho Server and retry the action that caused the original error. If it occurs again, shut down the Pentaho Server and open the catalina.out log file in Tomcat. The last line that appears before the error usually contains the name of the file that has been damaged.
When you have finished investigating, remove the extra logging capabilities so that your Pentaho Server log files do not become large and unmanageable.
Using the H2 database recovery tool
Read more about the recovery tool on the H2 Web site: http://www.h2database.com/html/advanced.html#using_recover_tool.
Follow these directions to use the recovery tool:
Open a terminal on (or establish an SSH connection to) your Pentaho Server.
Navigate to the /pentaho-solutions/system/jackrabbit/repository/version/ folder.
Run the h2-1.2.131.jar H2 database JAR with the recovery tool option.
java -cp h2-1.2.131.jar org.h2.tools.Recover
Create a directory to move your old database files.
Move the old database files to the directory created in the previous step.
mv db.h2.db db.trace.db old
Re-initialize the repository with the RunScript option using the salvaged SQL dump as the source.
java -cp h2-1.2.131.jar org.h2.tools.RunScript -url jdbc:h2:./db -user sa -script db.h2.sql
The backup directory you created earlier (old in the above example) can be removed after you are sure that you no longer need the corrupted database files.
Start the Pentaho Server and check for further errors. If repository errors persist, contact Pentaho support.
Unable to get list of repositories
There was an error posting the transformation on the remote server: org.pentaho.di.core.exception.KettleException: Unable to get a list of repositories to locate repository 'repo'To execute a job or transformation remotely on a Carte server, you first need to copy the local repositories.xml from the user's .kettle directory to the Carte server's $HOME/.kettle directory. The Carte service also looks for the repositories.xml file in the directory where Carte was started.
Importing and exporting PDI content with Pentaho 8.0 and earlier
When you export the contents of the repository from Pentaho version 8.0 or earlier and import them into a later version, an error occurs. This error may occur because you are attempting to export/import the entire repository, which may include items from repository locations that have restricted access in later versions of Pentaho.
Here's how you can resolve this error: To import or export PDI content that was created in Pentaho 8.0 or earlier, select specific content and not the entire repository. If you are working with multiple selections, export each one separately.
Also note that you do not need to export your Ops Mart content because it is automatically included and updated for each new version of Pentaho.
