  • What is the cause and solution for SAP error message VMC_ADMIN019 - Error while reading the shared lock data ?

    The SAP error message VMC_ADMIN019 indicates that there is an issue with reading shared lock data, which typically relates to the SAP system's ability to access or manage shared locks in the context of the Virtual Machine Container (VMC) or similar environments.

    Possible Causes:

    1. Database Lock Issues: There may be locks on the database that prevent the system from reading the shared lock data.
    2. Configuration Problems: Incorrect configuration settings in the SAP system or the underlying database can lead to this error.
