Switch To Java 11 on Synology and QNAP
Reconfigure LogicalDOC to use Java 11 on Synology and QNAP
Starting from version 8.3.4 LogicalDOC does not work with Java8 anymore so you have to install Java11.
It is important to install Java11 and not Java12 nor Java13, because Java11 is the latest LTS(Long Term Support) release available at the moment.
Given <LDOC_HOME> the installation path of LogicalDOC(by default it is /share/CACHEDEV1_DATA/.qpkg/LogicalDOC/ in QNAP and /var/packages/LogicalDOC/target/ in Synology), please proceed as follows:
1. Open a shell into your NAS as admin the cd to <LDOC_HOME>
2. Here execute the command wget https://service.logicaldoc.com/jdk/openjdk-11.0.2_linux-x64_bin.tar.gz
3. When the download completes, unpack the archive with the command
4. This creates a tray icon with the LogicalDOC’s logo tar xzf openjdk-11.0.2_linux-x64_bin.tar.gz
5. Right click on it and choose Configure...
6. Now open the Java tab
7. In the Java Virtual Machine put the full path of your jvm.dll (something like C:\Program Files\Java\jdk-11.0.4\bin\server)
8. In the Java Options text area, delete what you have and put this new text (remember to replace <LDOC_HOME> with your LogicalDOC’s installation folder):
9. Clear the Java 9 Options
10. Click on Apply and then Ok
11. Restart the LogicalDOC service
12. Open a shell as Administator and go to <LDOC_HOME>\update-wd
13. Execute the command update-wdw.exe //MS/LogicalDOC-Update
14. This creates another tray icon with the LogicalDOC’s logo
15. Right click on it and choose Configure...
16. Now open the Java tab
17. In the Java Virtual Machine put the full path of your jvm.dll (something like C:\Program Files\Java\jdk-11.0.4\bin\server)
18. Click on Apply and then Ok
19. Restart the LogicalDOC Update service
