Cannot switch to isolated mode

Hi everyone,

I am update to fs_2022.9 and switch to isolated mode (currently running in legacy mode)

What I did:

After copy fs-isolated-server.jar and wrapper.jar to /server/lib-isolated

And edit /bin.fs5.mode -> isolated

Copy fs-wrapper.isolated.conf   ~fs/conf/ fs-wrapper.isolated.conf

Server still in Legacy mode.

As I checked in system information:

 

ava.class.path

shared/lib-isolated/com.sap.security.api.jar
shared/lib-isolated/com.sap.security.core.jar
shared/lib-isolated/iaik_jce.jar
server/classes
server/lib/fs-server.jar > I think it should be server/lib-isolated/fs-isolated-server.jar
server/lib/wrapper.jar

 

 

Please help to fix this issue for me. Any advice are appreciated. 

Thank you very much!

Re: Cannot switch to isolated mode

Dear anhphamtuan83,

Have you updated the backend (unpacking the fs-update-3.0.1.tar.gz via the FirstSpirit installation directory)?
If so, did you then start the FirstSpirit server via the fs-server start script?

Hints:
The fs5 start script is outdated and cannot be used with 2022.9.
A start as a service configured with the old version could also cause the effect.
Have a look at the fs-wrapper.log - maybe you will find a hint there.

If these hints do not help, please contact our Tech Support so that the problem can be analysed.

Best regards

Good morning Holger,

Have you updated the backend (unpacking the fs-update-3.0.1.tar.gz via the FirstSpirit installation directory)?

Yes, I did.

The fs5 start script is outdated and cannot be used with 2022.9.
A start as a service configured with the old version could also cause the effect.
Have a look at the fs-wrapper.log - maybe you will find a hint there.

->  Yes I tried fs5 start. fs-warapper.log show like this:

Re: Cannot switch to isolated mode

Hello Tuan,

have you also tried "fs-server start"?

The exception sounds to me like an attempt to start a legacy server from an fs-isolated-server.jar. The start class does not exist, which is why the ClassNotFound exception occurs.

This could be because the outdated fs5 is used instead of the current start script fs-server.

Further pitfalls when updating very old FirstSpirit versions could be:
* Java version must now be at least 11
* The projects must have been migrated to Berkeley DB 7

Best regards
Holger
