Newbie: Installing Multiple MaxDB databases on single host

Hi

I would like to install multiple MaxDB databases (Development and QA) on the same host.

I would like to have these as completely seperate databases so that I can upgrade/patch one database instance without effecting any of the other MaxDB on the system.

I have just installed an SAP/MaxDB instance on one of the new servers and I have noticed that the independent Program path and the independent Data Path are set to e:\sapdb\programs and e:\sapdb\data respectively.

The only choice I had during the install was the drive letter.

If I install another instance will that be seperate instances or are there additional steps I need to undertake to achieve my goal??

Thanks

Doug

    Hello Doug,

    You could run the two database instances on one server, if you have enough OS resources on the database server: memory, CPU …

    And the database could be the different versions, the database software located in the independent program path is downward compatible, the programs and libraries from the IndepProgPath used by all database instances and applications, in the independent Program path you have the latest installed version of the database software => you should NOT worry about that.

    Please review the information at MAXDB library

    http://maxdb.sap.com/doc/7_6/default.htm

    -> Installation -> Installation Manual -> Details

    < -> Directories 😊 >

    Thank you and best regards, Natalia Khlopina

    We had problems with installtion Solution Manager 7.1 SR1 (MaxDB 7.8) on a system where already existed a SAP with SAP R/3 4.7 with MaxDB 7.7.

    We got following error:

    FJS-00003 TypeError: inst_name has no properties (in script NW_Onehost|ind|ind|ind|ind, line 35660: ???)

    and

    ERROR      2013-01-16 10:29:13.414 [sixxcstepexecute.cpp:937]

    FCO-00011  The step sdb_create_volumes_fs with step key |NW_Onehost|ind|ind|ind|ind|0|0|NW_Onehost_System|ind|ind|ind|ind|onehost|0|NW_CreateDBandLoad|ind|ind|ind|ind|createdbandload|0|NW_CreateDB|ind|ind|ind|ind|createdb|0|NW_ADA_DB|ind|ind|ind|ind|6|0|SdbPreInstanceDialogs|ind|ind|ind|ind|4|0|SdbInstanceDialogs|ind|ind|ind|ind|1|0|SDB_INSTANCE_CREATE|ind|ind|ind|ind|0|0|sdb_create_volumes_fs was executed with status ERROR ( Last error reported by the step: TypeError: inst_name has no properties (in script NW_Onehost|ind|ind|ind|ind, line 35660: ???)).

    We opened a message at SAP and got follwing answer:

    Edit file control.xml (located in installation directory)

    replace

    if (inst_name.toUpperCase() == dbname.toUpperCase()) {...

    with

    if (inst_name != undefined && inst_name.toUpperCase() == dbname.toUpperCase()) { ...

    Restart sapinst and continue at point it stopped.



    This worked.

    Hope that helps anybody.

    Regards

    Julia

      Hello Natalia,

      I didn't want to open a new thread, because this was one of the threads I found when I was looking for a solution for my problem.

      We changed control.xml after consulting SAP support. But we're facing now another problem: JDK/JVM seem to be too old and have to be updated.

      We decided now to wait with installation of solman until old SAP R/3 4.7 will have new release and new database.

      Regards,

      Julia
