Looks like the embedded h2 database is corrupted for some reason. The embedded database is for demonstration purpose and should not be used for production environment. You may need to delete the sampledb directory and then restore the database from an old backup.

Hi Robin,

Thanks for the quick follow-up.

I have a dbbackup, from about a year ago... Used for upgrading from 8.0 to 10.0.

Currently this is the DB back up that exist. Anyways, I tried to restore this using the command: restore "C:\Quickbuild\dbbackup~2020-06-13_09-28-46"

Ran into these issues:

Press any key to continue . . .

Let me know if there's a way for me to restore the DB without having to reconfigure my server.

Hi Robin,

Would like to add, I tried to open the .h2 file to see if I can fi the issue, unfortunately, it seems that the data became corrupted...

Let me know about your thoughts.

Is the path "C:\Quickbuild\dbbackup~2020-06-13_09-28-46" a directory? If yes, please check what contents is inside the directory. As to h2 database corruption, you may try h2 recovery tool to see if it helps:

Hi Robin,

We weren't able to recover, so we're trying to restore from our old DB back-up to reconfigure our system.

With that being said, we hooked up the DB connection to a local DB connection on the same machine, and we ran into a bit of issue.

Here is the error:

We declared an environment variable called CLASSPATH to the path of the required to the installed path: C:\Program Files (x86)\SQLJDBC_9.4\enu\mssql-jdbc-9.4.0.jre11.jar

I've also stored the JAR file's under the plugins/com.pmease.quickbuild.libs. Obviously instead of just the JAR file, we have the SQLJDBC_9,4\enu.... files under the path.

Let me know if I misunderstood the connectivity requirements.

Please place file "mssql-jdbc-9.4.0.jre11.jar" into directory /plugins/site
Also it is odd that your sql server driver class is "com.microsoft.sqlserver.jdbc.sqlserverdriver". It should be "com.microsoft.sqlserver.jdbc.SQLServerDriver" instead. Please check "conf/hibernate.properties" to make sure

Hi Robin,

Stored it .JAR file under /plugins/site and modified conf/hibernate.properties to the proper setting.
Still running into an error:

Removing the .JAR File produces the cannot find class of com.microsoft.sqlserver.jdbc.SqlServerDriver.
Do we need to unpack the .JAR files ourselves under the plugin library? Seems like there are issues with just providing the .JAR file inside plugins/site.
In addition to this: do the .JAR files require to be matching JDK? i.e. JDK 12 equates to JDBC Driver 7.4?

Hi Robin,

Weird, after waiting a day, and storing and unpacking the .JAR file under the plugins/com.pmease.quickbuild.libs path and also including the .JAR file here, it now finds the SQLServerDriver.

We are running into this error though:

Please do note, that when I use H2 Database (default), it allows the restore to work, but when trying to restore with the external DB, it throws this error...
Another thing as well, it seems like the QB_ID table has same inputs of name for one of the connectivity, and this is failing to insert it into the table properly. Due to this, I actually edited the value of 'Name' inside the .xml then zipped it back up to restore. Let me know if this isn't how I should handle this.

Let me know what I can do to fix.

There is an issue working with this version of jdbc driver. This has been fixed in 10.0.36:

Please go with below procedure:

1. Download and unpack 10.0.36
2. Copy file "mssql-jdbc-9.4.0.jre11.jar" into directory "<QB 10.0.36 dir>/plugins/site"
3. Edit "<QB 10.0.36 dir>/conf/hibernate.properties" to point to your SQLServer database
4. Clean your existing SQLServer database by deleting it and creating a new one with same name
5. Start QB to make sure it can starts with SQLServer
6. Stop QB, and run restore command to restore from your existing backup

Hi Robin, still the same failure if I put the .jar file inside: plugins/site of:

Caused by: java.lang.IncompatibleClassChangeError: class com.microsoft.sqlserver.jdbc.osgi.Activator can not implement org.osgi.framework.BundleActivator, because it is not an interface (org.osgi.framework.BundleActivator is in unnamed module of loader java.net.URLClassLoader @4b2c5e02)

If I move it inside plugin\com.pmease.quickbuild.libs and unpack it using jar xf mssql-jdbc-9.4.0.jre11.jar, and then try to launch my QB, no issues occur.

For now, I will keep it inside plugin\com.pmease.quickbuild.libs. Also, since it seems like QB has a duplicate key inside QB_ID (same value of 'name' inside ID's.xml) it will not load the restore in properly. The only fix I have is to manually edit the .xml to remove the duplicate key and put in a dummy one.

After that, it now interacts with the server. Any clue as to why it's like this and not working like how your suggestion is? Btw, I updated my QB to 11.0 (latest one).

Sorry I am wrong, the jdbc driver file should be placed into "plugins/com.pmease.quickbuild.libs". No need to unpack it, just place the jar file will be fine. As to name collision, this is because database field is case sensitive in embedded h2 database, while sql server is case insensitive by default.
