Online - Lock table overflow

Situation: I have Online 4.10 configured to support 10000 locks. All my tables are set for row level locking. I have 13 BIG files, in "unload" format, to load into 13 tables Problem with following sql: begin work; lock table table_01 in share mode; ... lock table table_13 in share mode; load from "file_01" insert into table_01; ... load from "file_13" insert into table_13; commit work; Having managed to load the first 2 tables it gets 3313 rows into table_03 and generates error 271 - Can't insert new row. All the remaining 10 loads fail imediately with the same error. In turbo.log I see 11 "Lock table overflow" messages. Now I thought I would not have any lock table overflow problems because I had lock the tables so no row level locking would be required. If I change the table lock mode to "exclusive" mode it works! Can some tell me what I missed? -- Paul Mahoney, X-Act Solutions Limited smail: 20 Shipley Lane, Cooden, Bexhill-on-Sea, East Sussex, TN39 3SR email: ptm@xact.demon.co.uk ... pmahoney@cix.compulink.co.uk phone: +44 424 3 6368
