The online function performs the following tasks:

• Performs a preliminary check to ensure that the SAP instance is not online on the specified node in the cluster.

• Removes any SAP processes that remain because of an unclean shutdown as follows:

  • If the SAP instance is APPSERV or ENQREP, the cleanipc utility gets executed. Otherwise, the agent kills all relevant SAP processes.

  • If the kill.sap and shutdown.sap file exists in the /usr/sap/SAPSID/InstName/work directory, the function removes the file from the directory.

  • Removes the SE and CO locks files from the /usr/sap/SAPSID/InstName/data directory.

• Initiates the standard SAP error log process.

• Starts the sapstartsrv process for Web-based SAP Management console.

• Starts the SAP instance using the sapstart command.

• Ensures that the instance is fully initialized.
