Refer to Allbase/SQL DBA Guide, pp3-28 ff - there are some formulae
about estimating the Control Block Buffer Pages. It involves estimation
of locks held - table, page, and row level. The range is 17 to 2,000
pages, with 37 as the default. PUBLIC vs. PUBLICROW declarations reduces
the need for Control Block Pages, if you don't really need row level
locking.

Hope that helps.

Subject: [HP3000-L] ALLBASE SQL questions


While running IMAGESQL:

>>SET SQLDBE ISEDB
>>SET TURBODB HEALTH.DATA
>>ATTACH
Split 16 compound source field(s) (ATCWARN 32063).
Mapped 1076 source table/source field name(s) (ATCWARN 32062).
ALLBASE/SQL CREATE TABLE command failed (ATCERR 32353).
  ALLBASE/SQL shared memory lock allocation failed in DBCore.  (DBERR
4008)

ACTERR 32353 points to the Allbase/SQL error messages.
DBERR 4008 says to use SQLUTIL to increase the number of control block
pages.

SHOWDBE tells me that there are 37 control block pages. I increased it,
arbitrarily to 100 and it seems to be working. How can I calculate the
proper number?

Thanks.
