Hi Stephen,
take a look at this
http://sapdb.2scale.net/moin.cgi/ChangesIn74

Question 1:

New parameter CACHE_SIZE is the sum of DATA_CACHE and CONVERTER_CACHE.
In contrast to 7.3 the page memory of 7.4 is more flexible. This
means that the data cache and the converter be able to grow or shrink
during online mode. 
For example: if the converter needes a new page frame and the page
frame allocator (component frame control) is empty the datacache
will be reduced about one page.

Question 2:

Yes, you are right. Caused by the new converter concept and the 
dynamic page frame allocation this parameter was removed.


BTW: For Further informations about the configuration
parameters you could use the dbmcli and the following
command:

param_getexplain <CONFIGURATION_PARAMETER>

Regards,
Torsten

Subject: SAPDB 7.3 to 7.4 changes when creating new database


Hi,

Is there a document that summarizes the changes in 7.3 to 7.4 when creating
/ tuning a database.

Questions:

1. Was DATA_CACHE changed to CACHE_SIZE parameter?  Is there any difference
in behavior?
2. Is MAXDATAPAGES obsolete in favor of new dynamic scheme?

Thanks.

  Stephen Gutknecht
