IT42699: MANY ATS/RIS FILES MIGHT GENERATED WHEN TABLE ARE CREATED WITH ERKEY AND WITH REPLCHECK

APAR status

• Closed as program error.

Error description

• Here is an example of the table and replicate setup which might
  result in the problem being seen ...
  
  create table t1 (id serial not null, c1 char(1) not null) with
  replcheck with erkey ;
  
  create index t1_rowid on t1 (id) using btree  ;
  
  create unique index t1_erkey_replcheck on t1 (ifx_erkey_1,
  ifx_erkey_2, ifx_erkey_3, ifx_replcheck) using btree  ;
  
  Please note that the inclusion of "with erkey" will
  automatically create a unique index on columns (ifx_erkey_1,
  ifx_erkey_2, ifx_erkey_3) which we will call erkey_123.
  
  When defining the replicate, then there will be a need to
  include "--erkey".
  
  cdr define replicate --erkey --conflict=ignore --ats --ris
  repl_t1 \
          "db@cdr_110:informix.t1" "select t.id, t.c1 from t1 t" \
          "db@cdr_111:informix.t1" "select t.id, t.c1 from t1 t"
  
  Once this replicate is operational, then an issue will be seen
  if the index data dictionary cache entries shows index
  t1_erkey_replcheck before index erkey_123.
  
  The order of indexes can be seen by running "onstat -g dic t1".
  
  Depending on the SQL being run on the source server, then the
  target server will report various ATS/RIS problems showing
  either dbop:update, dbop:delete, dbop:keydelete or
  dbop:keyinsert and the data will be out of sync.
