ABAP + JAVA + HANA on a single host using Solution Manager 7.2

Posted on Aug 19, 2016 at 12:28 PM 768 Views

Hi,

After reading through both the master and installation guides(including SCN and the forum) it is still not clear to me whether you are able to install Solution Manager 7.2 together on a single host with SAP HANA.

I see there is a note "1953429 - SAP HANA and SAP NetWeaver AS ABAP on one Server" but this specifically refers to ABAP and HANA and does not mention JAVA.

So can you or can you not have both stacks running together with HANA on a single system for Solution Manager 7.2 ? ...or do you have to run the JAVA instance on a separate host ?

Additionally, if I could get some examples of hardware used if this is the case it would be greatly appreciated.

Thanks.

Regards,

Nelis

    Hello Nelis,

    As you know HANA DB is supported only on Linux (Suse or Redhat) OS. see SAP Note 2235581 - SAP HANA: Supported Operating Systems

    So when you are installing DB you must use Linux as OS.

    Solution Manager 7.2 is not a dual stack system anymore. You must install ABAP and Java systems as seperate SAP systems.

    Here are the installation options;

    Option 1: Single host

    If your system resources (CPU, RAM, disk) are well you can install all parts of your SM 7.2 (DB+ABAP+Java) on one system. There will be no problem about it.

    Option 2: DB and SAPs are on seperate hosts

    Or you can install DB and SAP (ABAP+Java) on seperate systems (as we did on many customers). In this configuration HANA DB will be on linux system and ABAP and Java will be on linux or windows systems.

    Option 3: DB, ABAP and Java are all on different hosts

    If you want you can install ABAP and Java on seperate hosts additional to DB host. With this option you will have 3 hosts for Solution Manager System.

    If your HANA system is an appliance I advise you not to install SAP (ABAP+Java) on DB host. Using HANA appliance resources for SAP instances will cost you more. Instead use virtual machines as SAP instance hosts.

      Hi Nelis

      I suppose I have a different perspective.

      That SAP note is mentioned in multiple guides and it's mentioned as essential information / information on issues concerning installation/upgrade and so on.

      • The dual-stack of SAP Solution Manager 7.1 needs to be split in SAP Solution Manager 7.2. As a consequence the Application Server (AS) Java will become a new and separate SAP system.
        • Consider these split options in advance:
          • Host: Shall the AS Java remain on the same host as the AS ABAP (recommended) ?
          • Database: Shall the AS Java schema be kept in the same database (recommended) ?
            Note: Sybase databases do not support MCOD (operate several systems in one database). Therefore, you can only move the AS Java schema to a new database.

      The way I interpret this block is as follows: database recommendation from SAP is to keep the AS JAVA schema in the same database so MCOD architecture

      The "note: Sybase databases do not support MCOD" I then interpret as MCOD is supported for all DB's that are supported but Sybase.

      If you have a different opinion, perhaps the note or explanation isn't as clear as I thought it might be. In that case, it would make sense to provide feedback to SAP and ask them to provide more clear statements or guidelines.

      Best regards

      Tom
