Central System Log cannot be read

Hi all,

I have a NW 7.00 system just migrating from Windows to Linux and in SM21 I'm seeing

"central system log cannot be read /usr/sap/<SID>/SYS/global/SLOGJ"

Now SM21 still has some messages in it AOK so it must have it's local log to read, but it has no additional application servers so I see no technical need for collection of other logs into a central log.

Any idea then if
a) this should be ignored

b) there is parameter setting somewhere so that it knows not even to look for a central log

c) if there is some other likely error here to fix

I've tried testing by creating this log - that works AOK using "touch" but still the error appears.

I've been through thread sm21 GIVING ERROR

and the notes posted there but no resolution is forthcoming - in fact the SAP notes mentioned (also below) are focused on collection of remote logs into a central log and so don't really apply to my scenario.

I'm hoping a new discussion may kick this on.

Cheers, Jamie
