Starting the SAP Web Application Server outside a cluster
If you face problems while working with a resource, you must disable the resource within the cluster framework. A disabled resource is not under the control of the cluster framework, and so you can test the SAP Web Application Server independent of the cluster framework. Refer to the cluster documentation for information about disabling a resource. You can then restart the SAP Web Application Server outside the cluster framework.
Note:
Use the same parameters that the resource attributes define within the cluster framework while restarting the resource outside the framework.
A sample procedure to start a SAP Web Application Server outside the cluster framework, is illustrated as follows:
To start a SAP instance outside the cluster framework, using SAP MMC
- Log in to the system as a sapsidadm user.
- Use the SAP Microsoft Management Console (MMC) to start the SAP instance.
Ensure that the SAP instance starts successfully. If the instance starts successfully outside the cluster, you can attempt to start it inside the cluster framework.
To start a SAP instance outside the cluster framework, using the command prompt
- Log in to the system as a sapsidadm user.
- Start the SAP Windows service SAPSAPSID_xx for SAP instance, using the following command:.
drive\> net start SAPSAPSID_xx
- Use the startsap.exe utility to start the SAP instance. Enter,
drive\>usr\sap\SAPSID\InstName\exe\startsap.exe name=SAPSID nr=InstID sapdiahost=virtual_hostname
Ensure that the SAP instance starts successfully. If the instance starts successfully outside the cluster, you can attempt to start it inside the cluster framework.
