Is the platform down for maintenance? Or is something else happening?

Nov 16, 2017 at 09:02 AM | 1.1k Views | Last edit Nov 16, 2017 at 09:23 AM 2 rev.

Hello,

I'm trying to access the platform's (Message Management Service Cockpit) display stored messages, and i'm also trying to edit some of the configurations and i'm always receiving 500 Internal Server Error. Also from time to time i'm receiving a Websocket communication problem.

I'm just asking when will this be fixed.

Thank you,

David

    Dear Users,

    sorry for the late update. Unfortunately, the support of shared HANA DB on Trial has ended [1]. Starting from now, in order to run "iotmms" application, you would need to create the data source (HANA MDC or MaxDB) and respective data source binding manually. "iotmms" will not be able to create a schema (in the shared HANA) and data source binding automatically during deployment like it was before.

    We will adapt our documentation as well as "iotmms" deployment procedure accordingly.

    Sorry for the inconvenience,

    Anton

    P.S. "iotmms" might still work for those users who still have their shared HANA schema in place.

    Hello David,

    IoT MMS is a component which is deployed and running in consumer (your) account. I suppose you are using Trial landscape. Please check if the MMS is up and running. Applications in the trial landscape are automatically stopped after a certain period of time. You would need to start it new. See respective IoT FAQ [1]

    Regards,

    Anton

    Can you please post the server log here such that I can get more info on this. HANADB is actually down imu; so if u r using any schema related to it. it can be the reason.

    Hello Anton, Muhsin,

    The IoT MMS was deployed and running, hence i could actually enter the platform, but none of the services was actually working. Not even the display stored messages. I'm attempting now to stop and start the iotmms from the SAP Cloud Platform Cockpit. Hopefully this will make it work.

    I'll come back with a later edit when it will start again. Maybe with some printscreens as well.

    Thanks for the fast replies.

    David

    Hello guys,


    Later edit on the start/stop of the MMS service.

    While trying to start the platform the logs return:

    2017 11 16 12:28:35#+00#ERROR#com.sap.cloud.runtime.kotyo.persistence.client.datasource.DataSourceFactory##anonymous#localhost-startStop-1#na#p1943017867trial#iotmms#web##na#na#na#na#Failed to open SSL test connection, encrypted communication with server failedcom.sap.db.jdbc.exceptions.JDBCDriverException: SAP DBTech JDBC: Cannot connect to jdbc:sap://vadbjn1.nwtrial.od.sap.biz:30015/ [Cannot connect to host vadbjn1.nwtrial.od.sap.biz:30015 [Connection refused (Connection refused) (local port 49267 to address 0.0.0.0, remote port 30015 to address 10.117.12.88 (vadbjn1.nwtrial.od.sap.biz))], -813.].

    I have the same issue :|

    I am unable to successfully start the IoT MMS component. Does anyone know how long this downtime would last?

    This is the one of the errors:

    2017 11 20 13:26:11#+00#ERROR#com.sap.cloud.runtime.kotyo.persistence.client.datasource.DataSourceFactory##anonymous#localhost-startStop-1#na#p442125trial#iotmms#web##na#na#na#na#Failed to open SSL test connection, encrypted communication with server failedcom.sap.db.jdbc.exceptions.JDBCDriverException: SAP DBTech JDBC: Cannot connect to jdbc:sap://vadbjn1.nwtrial.od.sap.biz:30015/ [Cannot connect to host vadbjn1.nwtrial.od.sap.biz:30015 [Connection refused (Connection refused) (local port 43494 to address 0.0.0.0, remote port 30015 to address 10.117.12.88 (vadbjn1.nwtrial.od.sap.biz))], -813.].

      Thanks Rob, It worked for me .

      It is worth noting that we need to create Data Source Binding from Java Application >> IoT Application >> Configuration >> Data Source Bindings and not from DataBase and Schema >> db >> Data Source Bindings.

    The second solution described at https://archive.sap.com/discussions/thread/3825912 worked for me:

    1. stop MMS
    2. remove the binding to MMS from <s-user>trial.iotmms.web schema
    3. delete the the <s-user>trial.iotmms.web schema => Connection refused
    4. create a new schema => Create a Database, e.g. iotmms2. Assign role IoT-MMS-User to your s-user
    5. bind it to MMS app
    6. start MMS (After one hour)

    Downside: After 12 hours, the trial tenant database is shut down, and if you do not use it for 7 days, it is automatically deleted.

    Best regards,

    Theo

      Unfortunately, an issue with the shared HANA DB on Trial is still valid. So, in order to start iotmms, you would need to bind it either to MaxDB or HANA MDC.

    Hi,

    im facing the same issue on hanatrial. I already tried to add a new binding to the mms Service but this isn't working to.

    Regarding to Robs workaround:

    4). Delete the existing binding with the shared DB.

    there were no existing binging is was empty.

    Has someone any idea how to fix this problem ?

    best regards,

    Daniel
