Answer / jaya

When you shutdown SAP, the log is stored at the UNIX level
startsap.log, stopsap.log in the home
directory. /home/<sid>adm/...

I assume you are refering to SAP Patches and not DB. The
patches are usually a Code sets, or you can say kind of
Transports. And those need RDDIMPDP scheduled and running
as a backup job. RDDIMPDP is a CTS deamon.

You can see the log /usr/sap/trans/log.

You have to check the timestamp on ULOG, SLOG and do
a "more" on the file.

Good Luck.

Hi,

1.What happens when in background when we shutdown SAP
(Both
central & Database

Here is the sequence of what happen in the background-what
ever ur os might be.

If its abap+java system
First java apps goes down,then java dispatcher,then abap
work process, then abap dispatcher,,then the message
server.. All the logs will be written in usr\sap\..\work

2.Also when we apply the Patches, what exactly is running
in background..

I assume that you are talking about Support packs.
What is actually happening in background is is updating the
objects,,components-this depens upon the type of support
pack.
in OS level tp and r3trans process are used.
The logs are written in usr\sap\trans\log and intermediate
temp logs are written in usr\sap\trans.

hope helps

As per the previous Consultant RDDIDMP is a cts deamon.
when ever the sap sstem is shutdown in the mean we can get
the information abt the sap system in event viewer too and
in the home directory of the Unix machine

Applying Patches is completely a different process . its an
Correction for the bundle of errors reported to SAP.
here we system will generate teh Request no for teh further
transport of request in the other system
kindly download and uncar the files and approve it and
apply that in to teh systems
so here required is the import dispatcher.(which is
scheduled in the background job in ddic client 000)

Kindly suggest if anything is wrong.plz
