Hi Jennah,
As per note 869267,
- How can I reduce the size of an existing log configuration?
the only way to adjust the size is to do the recovery with initialization.
The content server should be always accessed from SAP work process level, I do not think the sessions will be much. You can refer to notes below, to adjust the parameters:
1004886 - parameters 7.7
1308217- Parameters 7.8
1346964 - SAP MaxDB Version 7.9 parameter recommendations
Cheers,
James
