Using the HCP predictive service - the application is under maintenance

[Former Member]

Hi Experts,

Recently I would like to try the predictive service on HCP.

According to SAP HANA Cloud Platform predictive services User Guide

I have requested a dedicated HANA instance, install the APL and deploy the service.

It seems the application starts successfully.

But when using the API, it always return:

{

    "errors": [

        {

            "errorMessage": "The application is under maintenance, please contact your account admin for more details.",

            "errorCode": "EXXXX"

        }

    ]

}

I cannot find more detailed information about the errorCode and then I tried to check the data source and roles, restart several times.

But after hours struggling, I still face the same problem.

Any idea on the above issue? Your help is very appreciated.

Best Regards,

Qinhe, Lin

Hi,

Please check you have HANA SP9 and APL2.4 installed, and a schema correctly binded to the application with sufficient rights SAP HANA Cloud Platform predictive services User Guide

Hi Songlan,

By APL 2.4 I assume you mean the software download below? (SA PA APL 2.4 for HANA SP9)

Hi Antoine,

Yes it is the same APL, but HCP provides a self-service to install APL directly into the dedicated hana instance associated to the HCP account, so no need to download

Hi Songlan,

I find that my instance is of SPS 10 and the current APL version is of 2.2.

Two questions:

- Is it OK to work on the revision 102?

- Should I update the APL to 2.4 now in HANA SP10?

Best Regards,

Hi,

If the HANA instance of your HCP account is SP10, do the following steps:

1. upgrade to at least the version1.00.102.03

2. install the lastest version of APL (2.4 for now)

3. grant the role sap.pa.apl.base.roles::APL_EXECUTE to the hana schema binded to aac4paservices

And the predictive services will work:)

Hi Lin,

Did you take a look at the application logs? You can even enable 'debug' level logs for more information.

you can also try the url "/admin/status" to have an overview of the app status and which component is reporting an error.
