SAPHana - SAP HANA on Amazon
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

SAPHana

Create a file called "crm-saphana.txt" with the following cluster bootstrap options for SAP HANA:

prihana:~  cat crm-saphana.txt
primitive rsc_SAPHana_HDB_HDB00 ocf:suse:SAPHana \
        op start interval="0" timeout="3600" \
        op stop interval="0" timeout="3600" \
        op promote interval="0" timeout="3600" \
        op monitor interval="60" role="Master" timeout="700" \
        op monitor interval="61" role="Slave" timeout="700" \
        params SID="HDB" InstanceNumber="10" PREFER_SITE_TAKEOVER="true" \
        DUPLICATE_PRIMARY_TIMEOUT="7200" AUTOMATED_REGISTER="true"
ms msl_SAPHana_HDB_HDB00 rsc_SAPHana_HDB_HDB00 \
        meta clone-max="2" clone-node-max="1" interleave="true"

Update the value of parameters SID and InstanceNumber with your SAP HANA system information. In addition, update the SID and Instance number referred in the rsc_SAPHana_<SID>HDB<Instance Number> and msl_SAPHana<SID>_HDB<Instance Number> configuration.

Note

You can find the detailed information about all the parameters with the command "man ocf_suse_SAPHana"

Add the SAP HANA configuration file to the cluster with the following command:

prihana:~  crm configure load update crm-saphana.txt

When using an SAP HANA version with systemd integration (SPS07 and later), you must run the following steps to prevent the nodes from being fenced when Amazon EC2 instances are intentionally stopped.

  1. Verify if SAP HANA is integrated with systemd. If it is integrated, a systemd service name, such as SAP<SID>_XX.service is present. For example, for SID`HDB and instance number 00, `SAPHDB_00.service is the service name.

    Use the following command as root to find SAP systemd services.

    prihanadb:~  systemctl list-units | grep SAP
  aws-dataprovider.service                                                loaded active running   {aws} Data Provider for SAP
  pacemaker.service                                                       loaded active running   pacemaker needs SAP instance service
  SAPHDB_00.service                                                       loaded active running   SAP Instance SAPHDB_00
  saphostagent.service                                                    loaded active running   SAP Host Agent
  SAP.slice                                                               loaded active active    SAP Slice

  2. Create a pacemaker service drop-in file.

     mkdir -p /etc/systemd/system/pacemaker.service.d/
cat <<_EOF > /etc/systemd/system/pacemaker.service.d/00-pacemaker.conf
[Unit]
Description=pacemaker needs SAP instance service
Documentation=man:SAPHanaSR_basic_cluster(7)
Wants=SAP<SID>_<XX>.service
After=SAP<SID>_<XX>.service
_EOF

  3. Enable the drop-in file by reloading systemd.

     systemctl daemon-reload

  4. Verify that the change is active.

     systemctl show pacemaker.service | grep SAP<SID>_<XX>

    For example, for `SID`HDB and instance number 00, the following output is expected.

     systemctl show pacemaker.service | grep SAPHDB_00
Wants=SAPHDB_00.service resource-agents-deps.target dbus.service
After=system.slice network.target corosync.service resource-agents-deps.target basic.target rsyslog.service SAPHDB_00.service systemd-journald.socket sysinit.target time-sync.target dbus.service sbd.service
