DSE Persistence Not Working

ahamad · ‎Dec 17, 2018

Hi,

I have installed Thingworx (Postgres version) 8.3.0 on 1 machine, Postgresql on 1 machine, and DSE on 1 machine.
I have imported the dse persister provider package and created a Persistence Provider for that package and created a Value Stream based on ValueStream template.
I created a new template with some properties, and assigned the value stream created above, then created a thing based on that template. The created properties are of type "NUMBER" and "Logged" is checked
I'm using Administrator account
If I try to change the value of a property from Composer or using Postman (REST APIs) I get the similar error
- Postman: 500, Internal Server Error, com/thingworx/common/utils/SerializationOptions
- Composer: Unexpected error occurred on server
  - Application Log shows -- [context: com.thingworx.webservices.context.HttpExecutionContext@5daf065d][message: com/thingworx/common/utils/SerializationOptions]
  - Browser console shows -- No key tw.response.com/thingworx/common/utils/SerializationOptions found!

If I hit the refresh button in Composer I can see the value changes to the new value set, however when I try to execute the service QueryPropertyHistory I get an empty result. I verified using DSE CQLSH to query tables and they are all empty

More Findings

The error disappears if I uncheck "Logged" on the property. This means it is an issue with DSE persistence package or the configuration
Clicking Import > Manage Extensions shows that the imported DSE extension is for Thingworx 8.2.9 and I have Thingworx 8.3.0. Would that be the issue? If so, where would I find the proper DSE extension for 8.3.0? The package that was imported is named MED-61150-CD-083_F000_DSE-Persistence-Provider-Extension.zip. (It was downloaded from under Release 8.3 and the name indicates 083)
I'm using DSE 5.0.15. Is that ok?

When you created and configured your new DSE persistence provider, were there any errors? Once you name a tablespace, it should get created and be seen on the DSE side.

Currently the only versions supported and tested are 4.6.3 through 5.0.0.

Hello,

When I create the DSE Persistence Provider there are no errors. It returns a success message and I can see the schema and all the tables created on DSE (cqlsh > describe thingworxnd;)

I was using DSE 5.0.15 and I downgraded to DSE 4.8.16 and still having the exact same issue,

Any help on this? Still facing the issue.

I'm getting the following stack trace in catalina.out if I try to use the Academic Simulator to simulate data
