Manages a sap database instance as an ha resource.
SAPDatabase [start | stop | status | monitor | meta-data | validate-all]
Resource script for SAP databases. 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 and 11.2
- 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 node 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
SID
The unique database system identifier. e.g. P01
(unique, required, string, no default)
DIR_EXECUTABLE
The full qualified path where to find saphostexec and saphostctrl. Usually you can leave this empty. Then the default: /usr/sap/hostctrl/exe is used.
(optional, string, default "/usr/sap/hostctrl/exe")
DBTYPE
The name of the database vendor you use. Set either: ADA, DB6, ORA, SYB, HDB
(required, string, no default)
DBINSTANCE
Must be used for special database implementations, when database instance name is not equal to the SID (e.g. Oracle DataGuard)
(unique, optional, string, no default)
NETSERVICENAME
Deprecated - do not use anymore. This parameter will be deleted in one of the next releases.
(optional, string, no default)
DBJ2EE_ONLY

(optional, boolean, default false)
JAVA_HOME
Deprecated - do not use anymore. This parameter will be deleted in one of the next releases.
(optional, string, no default)
STRICT_MONITORING
This controls how the resource agent monitors the database. 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.
(optional, boolean, default false)
AUTOMATIC_RECOVER
If you set this to true, 'saphostctrl -function StartDatabase' will always be called with the '-force' option.
(optional, boolean, default false)
MONITOR_SERVICES
Defines which services are monitored by the SAPDatabase resource agent, if STRICT_MONITORING is set to true. Service names must correspond with the output of the 'saphostctrl -function GetDatabaseStatus' command.
(optional, string, default "Instance|Database|Listener")
DIR_BOOTSTRAP
Deprecated - do not use anymore. This parameter will be deleted in one of the next releases.
(optional, string, no default)
DIR_SECSTORE

PRE_START_USEREXIT
The full qualified path where to find a script or program which should be executed before this resource gets started.
(optional, string, no default)
POST_START_USEREXIT
The full qualified path where to find a script or program which should be executed after this resource got started.
(optional, string, no default)
PRE_STOP_USEREXIT
The full qualified path where to find a script or program which should be executed before this resource gets stopped.
(optional, string, no default)
POST_STOP_USEREXIT
The full qualified path where to find a script or program which should be executed after this resource got stopped.
(optional, string, no default)
