It manages a SAP database of any type as an HA resource. The purpose of the resource agent is to start, stop and monitor the database instance of a SAP system. Together with the RDBMS system it will also control the related network service for the database. Like the Oracle Listener and the xserver of MaxDB. The resource agent expects a standard SAP installation of the database and therefore needs less parameters to configure. The resource agent supports the following databases: - Oracle 10.2, 11.2 and 12 - DB/2 UDB for Windows and Unix 9.x - SAP-DB / MaxDB 7.x - Sybase ASE 15.7 - SAP HANA Database since 1.00 - with SAP note 1625203 (http://sdn.sap.com) In fact this resource agent does not run any database commands directly. It uses the SAP standard process SAPHostAgent to control the database. The SAPHostAgent must be installed on each cluster node locally. It will not work, if you try to run the SAPHostAgent also as a HA resource. Please follow SAP note 1031096 for the installation of SAPHostAgent. The required minimum version of SAPHostAgent is: Release: 7.20 Patch Number: 90 or compile time after: Dec 17 2011 -A single HANA is managed as a primitive resource by the SAPDatabase RA. Therefor the parameter MONITOR_SERVICES has to match the output service names of the command "sapcontrol -nr \$InstNr -function GetProcessList". -"\$InstNr" has to be replaced by the respective instance number. +To exemplify the usage, for a HANA database with SID "TST" and instance number "10", the resource configuration using crmsh syntax looks like: -For an HANA database with SID "TST" and instance number "10", the resource configuration looks like: primitive rsc_SAPDatabase_TST_HDB10 ocf:heartbeat:SAPDatabase \\ params DBTYPE="HDB" SID="TST" \\ - MONITOR_SERVICES="hdbindexserver|hdbnameserver" \\ op start interval="0" timeout="3600" \\ op monitor interval="120" timeout="700" \\ op stop interval="0" timeout="600" + +Make sure to tune the operations timeout values accordingly with your chosen Database and available infrastructure. + +Note that the same configuration can be achieved using any other CLI tool for cluster configuration available, like pcs or cibadmin.

If set to true, it will use 'saphostctrl -function GetDatabaseStatus' to test the database state. If set to false, only operating system processes are monitored.

Enable or disable automatic startup recovery Defines which services are monitored by the SAPDatabase resource agent. Service names must correspond with the output of the 'saphostctrl -function GetDatabaseStatus' command. -The default value is derived from the database type DBTYPE.
