These attributes are taken by the SAPHana RA to control the SAP Hana Databases. In addition it starts and monitors the local saphostagent. 1. Interface to monitor a HANA system: landscapeHostConfiguration.py landscapeHostConfiguration.py has some detailed output about HANA system status and node roles. For our monitor the overall status is relevant. This overall status is reported by the returncode of the script: 0: Internal Fatal 1: ERROR 2: WARNING 3: INFO (maybe a switch of the resource running) 4: OK The SAPHanaTopology resource agent will interpret returncodes 1 as NOT-RUNNING (or 1 failure) and returncodes 2+3+4 as RUNNING. SAPHanaTopology scans the output table of landscapeHostConfiguration.py to identify the roles of the cluster node. Roles means configured and current role of the nameserver as well as the indexserver. 2. Interface is hdbnsutil The interface hdbnsutil is used to check the "topology" of the system replication as well as the current configuration (primary/secondary) of a SAP HANA database instance. A second task of the interface is the posibility to run a system replication takeover (sr_takeover) or to register a former primary to a newer one (sr_register). 3. saphostctrl The interface saphostctrl uses the function ListInstances to figure out the virtual host name of the SAP HANA instance. This is the hostname used during the HANA installation. </longdesc> <parameters> <parameter name="SID" unique="0" required="1"> <longdesc lang="en">The SAP System Identifier (SID)</longdesc> <shortdesc lang="en">The SAP System Identifier (SID)</shortdesc> <content type="string" default="" /> </parameter> <parameter name="InstanceNumber" unique="0" required="1"> <longdesc lang="en">The SAP Instance Number</longdesc> <shortdesc lang="en">The SAP Instance Number</shortdesc> <content type="string" default="" /> </parameter> <parameter name="DIR_EXECUTABLE" unique="0" required="0"> <longdesc lang="en">Path to the SAP Hana Instance executable directory.
