I'm currently updating our JDI server from SP Stack 09 to 12.
I'm using "SAP Netweaver '04 SP Stack 12 Guide", and in the document, it says that I have to use SAPinst to apply the .SAR files (J2EERT, SAPINST, CTRL, J2EERTOS).
Where can I find this SAPinst tool? Is this the startinstgui.bat in the Master DVD of NetWeaver '04? I keep on getting an error when I enter the hostname and port no.
