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 SAP DB, SAP Labs Berlin -----Original Message----- From: Stephen Gutknecht (SAPDB) [mailto:[EMAIL PROTECTED] Sent: Donnerstag, 13.

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.
