RAC Tests

Hello,

I saw documentation for the RAC installation in SAP, however i can not find any list or suggestions for test the High Availability of RAC in a SAP enviroment.

Does anyone could advice ?

TAF is configured at the listener level as oficial sap-rac documentation, but i dont know how works with sap

Shall i expect that the sap transaction still working after an instance failed ?

Does the sap session still connected and the sap transaction will died ?

Best Regards & Thanks in advance,

sapcrosas

    Hi,

    please keep in mind if you use RAC, you have only a HA of the instances not of the db, the db is everytime the same one. So in my opinion it´s not a complete HA solution, if your db crashes your HA of your instances won´t help you 😉

    If you are interesting in HA refer to physical data guard.

    I don´t have any experience with RAC, so I don´t can answer your RAC questions.

    Regards,

    Jens
