Question about Go Live Check



What's Go-Live Check?
Who's responsible for Go-Live Check?
What should we prepare before Go-Live Check?
How many times for Go-Live Check?(I mean that Go-
Live Check seperate into how many steps/types such as 3 times for 1 Month before Go-Live, 2 Weeks before Go-Live
and 2 Weeks after Go-Live etc.) What's recommend schedule for each time?
How can we proceed Go-Live Check?

You have to open a message in component XX-SER-TCC to find out if your installation is scheduled for a Go-Live check which is conducted by SAP and it’s partners.
Go-Live Functional Upgrade Analysis – ideally 6 months before Golive – basically checks your hardware requirement , will it be able to accommodate the increase in the functionalities caused by the Go-Live, also some parameter recommendations to fine-tune your system.
Go-Live Functional Upgrade Verification – This is normally 2 months after the Go-live which is to see e’thing is fine after the upgrade.
Then you have normal Earlywatch session , each installation is entitled for 2 free earlywatch session in a year, in this performance tuning is done for your system, hardware,memory, I/0 bottlenecks are identified.

Reports of all these sessions carried out by SAP is then sent to you in form a MS-Word document and you can follow the guidelines mentioned and call up SAP or mail the person who has done the session for you for any clarifications.
Usually once a session is scheduled.
SAP will contact you to open the connections for them, so that they can prepare the system before the actual session takes place , in which they see , if SDCC version is good enough so that they can download the data from your system into their internal system on which they carry out the analysis, see if SAPOSCOL is running and enough history data is there in ST03n for them to carry out reasonable analysis. If e’thing is set a download is scheduled on your system using SDCC for a day prior to the actual session , and on the day of the session you open the connections for them again and provide them with userid and password normally it is earlywatch in 066 client.
