7.10 problems

Good day, We seem to be going through lots of problems with our implementation of the OnLine Engine. We're running 7.10.UD3 on an HP-9000/I70 (2 processors) with 10.01 HP/UX. The database was created using DBNLS = 2. We are running with 33 DB Spaces and 320 MB of RAM. There are 50 users accessing from IPCSHM and 50 configured for SOCTCP. Shared memory occupies approximately 80MB of RAM with enough virtual memory that we no longer keep dynamically allocating additional memory segments. The database was originally in a separate DBSpace but was placed in the rootdbs this time around thinking that might have something to do with our problems. The logical logs and the physical log are in 3 separate DBSpaces. (logical logs are split across 2 with even IDs in one and odd IDs in another). Anyway, here's a brief synopsis of some of the issues. Yesterday morning I attempted to execute a "oncheck -cc" and it immediately returned an error code 0 (zero), Unknown Error Code. A call to Tech Support resulted is unloading the data (150M rows), recreating the database, and them loading back the data. Along the way of reloading, we started executing a "oncheck -cDI" and it told us that that some indexes were not correct. The message on the screen suggested that we drop the offending indexes and rebuild them. We dropped, rebuilt and again ran "oncheck -cDI" with the same results. We dropped, rebuilt and again ran oncheck with the same results. We dropped, rebuilt... Well you get the picture. We tried putting the index in a separate DBSpace without success. We also cannot create an index without specifying the DBSpace. If we attempt to create an index with "create index idx_ux1 on table(col_nam)", the engine crashes with an Assert Failure, Arithmetic Exception error. If we issue "create index idx_ux1 on table(col_nam) in dbs01", the index builds and the engine is happy. I realize that this is a lot of information to digest but we've been working with this problem and others for several weeks and are not getting any answers from Tech Support. ANY HELP WOULD BE GREATLY APPRECIATED! Keith Howard Director CMS Technologies Reynolds & Reynolds 708-297-2300x332
