|

|
||
|
|

|
||
|
|
+The SAPHanaSR resource agent manages two SAP Hana instances (databases) which are configured
|
||
|
|
+in system replication. This first version is limitted to the scale-up scenario. Scale-Up is
|
||
|
|
+not supported in this version.
|
||
|
|
+
|
||
|
|
+Managing the two SAP HANA instances means that the resource agent controls the start/stop of the
|
||
|
|
+instances. In addition the resource agent is able to monitor the SAP HANA databases to check their
|
||
|
|
+availability on landscape host configuration level. For this monitoring the resource agent relies on interfaces
|
||
|
|
+provided by SAP. A third task of the resource agent is to also check the synchronisation status
|
||
|
|
+of the two SAP HANA databases. If the synchronisation is not "SOK", than the cluster avoids to
|
||
|
|
+failover to the secondary side, if the primary fails. This is to improve the data consistency.
|
||
|
|
+
|
||
|
|
+The resource agent uses the following four interfaces provided by SAP:
|
||
|
|
+
|
||
|
|
+1. sapcontrol/sapstartsrv
|
||
|
|
+ The interface sapcontrol/sapstartsrv is used to start/stop a HANA database instance/system
|
||
|
|
+
|
||
|
|
+2. landscapeHostConfiguration
|
||
|
|
+ The interface is used to monitor a HANA system. The python script is named 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, 4: OK
|
||
|
|
+ The SAPHana resource agent will interpret returncodes 0 as FATAL, 1 as not-running or ERROR and and returncodes 2+3+4 as RUNNING.
|
||
|
|
+
|
||
|
|
+3. 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).
|
||
|
|
+
|
||
|
|
+4. hdbsql / systemReplicationStatus
|
||
|
|
+ Interface is SQL query into HANA (system replication table). The hdbsql query will be replaced by a python script
|
||
|
|
+ "systemReplicationStatus.py" in SAP HANA SPS8 or 9.
|
||
|
|
+ As long as we need to use hdbsql you need to setup secure store users for linux user root to be able to
|
||
|
|
+ access the SAP HANA database. You need to configure a secure store user key "SAPHANA${SID}SR" which can connect the SAP
|
||
|
|
+ HANA database:
|
||
|
|
+
|
||
|
|
+5. 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.

|

|
+landscapeHostConfiguration.py has some detailed output about HANA system status
|

|
|
+and node roles. For our monitor the overall status is relevant. This overall
|

|
+0: Internal Fatal
|
||
|
|
+1: ERROR
|

|
+2: WARNING
|

+3: INFO (maybe a switch of the resource running)

|

|
|
+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.
