Re: Oracle CDC Experiences

Andrew,
   
  If instead of sending your responses directly to me, you send them to the DW 
product managers at Oracle, that would be equally acceptable.   They wanted 
feedback from me and others.  I suggested that the folks here at oracle-l, 
which I follow daily, might have a lot of valuable feedback and asked if it 
would acceptable to them if I solicited the folks on oracle-l on their behalf.
   
  They were fine with that and are not members of this list, so it made sense 
that I sent out the request.  You are also more than welcome to respond at 
firstname.lastname@xxxxxxxxxx for me (Job Miller). 
   
  I didn't want their inboxes to be bombarded with thoughts.  I had hoped to 
collect your survey data and send it on to them in a consolidated mailing.  I 
don't know their intentions for the data, but if they want to discuss further 
with you about your environment/issues, I'd bet they would want to know who you 
are and who you work for also.
   
  Someone else also pointed out that it would be helpful to know the volume of 
data you are capturing/processing via CDC.
   
  CDC (especially async CDC) as described in the DW concepts manual (10g+) is 
not very often discussed here it seems.  There have been a few threads on it 
over the last couple years since I have been reading oracle-l, but not many.   
   
  Thanks,
   
  Job Miller

  The problem is we don't know that you are who you say you are.  It would be 
grossly irresponsible for someone to answer this type of survey just because 
you say you work for Oracle.  Its one think to ask and answer questions, which 
is the intent of this list.  It is another thing to answer random questions 
about their environment.  Especially since if you follow the list, you can 
probably figure out the company even if they dont put it on the survey answers. 
 If you really need answers to a survey like this, point us to a link on the 
metalink or otn site.
