    • Hello Akshay,

      -> Did you already open the OSS message, where this issue was reported?

      -> If the liveCache & application running on the different servers, please

      check/install the liveCache client software on the application server for

      the livecache applications to be able to communicate to the liveCache on

      your system.

      Please follow the SAP note :: 649814 Updating MaxDB/liveCache client software

      to install the liveCache software on the application server.

      For additional information please review the SAP note::

      822239 FAQ: MaxDB Interfaces

      Thank you and best regards, Natalia Khlopina

      PS to Mag:

      The database log files & dbm* protocols are located in the database RUNDIRECTORY on the database server. The RUNDIRECTORY is the database parameter.

      You could use the database tool xinstinfo, for example, to display the information::

      xinstinfo <DB-name>

      => you will see in the output the settings for

      IndepData : …

      IndepPrograms : …

      InstallationPath : ...

      Rundirectory : …

    if you're using liveCache (and thus SCM), then it's very likely you're an official SAP customer: I'd suggest to open an OSS message (if not already done).

    Regarding your issue, please check if you can see the SAPDB_DBM and SAPDB_DBM_DAEMON are existant in transaction SM59 (under TCP/IP connections) and check to see if they work.

    Additionally, is the liveCache Client software installed on the machine on which you're trying to connect to the liveCache? Can you issue DBMCLI commands (like 'dbmcli db_enum') on the commandline on that machine?
