In Response To: Re: dbschema : 100 - ISAM error: duplicate value f (Art Kagel)

Hi Art,

yes , you are right I'm using the -ss option,
in fact I'm using : dbschema -d isa -ss > isa.sql

I started it once more and now it's going further, the error appears when generating the "create index"-statements.

create unique index "root".iprw1 on "root".iprw (nina,tarif,ddeb

desc) using btree in par1 ;
create index "cti".acth1 on "cti".acth (nmed) using btree in

chrvs1 ;
100 - ISAM error: duplicate value for a record with unique key.

Could it be because I run the dbschema while everyone is still working (~ 150 sessions active) ?

I've run this several times before without any problems, during migrations, always in addition
to the dbexport, but then of course no one is connected.

Thx,

Jacques

I'm going to guess that you are using the output of dbschema -ss to recreate
an existing database on another server or a differently named database with
the same set of tables. If that's so, the problem is that the script
contains a combination of named and unnamed indexes and constraints and some
of the named objects are clashing with unnamed objects for which the engine
has generated default names. IDS is generating different names for the
implicitly named objects than it did in the source database and these names
are clashing with some of the explicit object names.

The most likely culprit is an index or constraint on this particular table,
acth, but that depends on how you were running the dbaccess session and how
you determined where the problem was encountered. It could be a table later
in the file.

One solution is to use my dbschema replacement utility, myschema, to get the
schema from the source database. Myschema was specifically created to avoid
these kinds of problems. It creates explicit names for all implicitly named
objects in the output schema. The explicit names are based on the existing
implicit names in the source server so there can be no clashes in the target
server when you execute the DDL script.

Myschema is contained in the package utils2_ak which you can download from
the IIUG Software Repository (www.iiug.org/software) or from the Oninit web
site (www.oninit.com/utils).
