How many bytes does a refresh check on the DDLOG table cost?

64 Views

Hello,

each application server checks after "rdisp/bufrefreshtime" in the DDLOG table on the database whether one of it's tables or entries of tables are invalid.

Only tables or entries of tables that are invalid appear in the DDLOG table. If an application servers gets to know which of his tables are invalid, he can synchronize with the next read access.

Does anybody know how many bytes such a check cost?

The whole DDLOG must be read by each application server, so it depends on the number of entries in the DDLOG.

Does anybody know?

thx, holger
