Good truth migration between Oracle and PostgreSQL are not things difficult: Indicates that your database has: Tables: 20 Shema:? functions:? Views:? They need help to migrate ... Or what are you suggestions if you need a tool that already does this task for you good people have a tool interprisedb postgres'm not recommending eye but no way they already have. : s El jue, 07-07-2011 a las 09:55 -0400, akp geek escribió: We have 20 tables in oracles that we needed to get to postgres -- __ Ing.

We have 20 tables in oracles that we needed to get to postgres. Appreciate your help I have used ora2pg. It was not seamless -- I had to do some whacking around of the produced files, and I had a pretty good idea of what changes were needed in the ora2pg tool to improve things, but I didn't have time to implement them. It was still a lot easier than trying to do it all by hand.

Hello, I do no have any experience with oracle, try to dump the oracle database in plain format and then try to execute the DDL and DML statements. It might be cumbersome to fix all the errors you might get. But as an initial solution give it a shot.

It might be cumbersome to fix all the errors you might get. But as an initial solution give it a shot. I have migrated mysql, oracle, ingres and SqlSvr databases to Postgres and in pretty much all cases around 30% of the activity has been application specific code changes or replacing Oracle or SS7 specific optimisations with pg equivalents. An example is the insert then update order issue on a unique keyed table. The order does make a differenet in processing time and if within a stored procedure I often find the procedure has to be redone to ensure it performs as expected. Things like this tend to be missed by automated Ora-Pg toolsets. I have never used the commercial Oracle portability layers but have heard good things about them. If you have no procedural code or triggers then migration is usually a few days application review work...

Re: [GENERAL] Oracle to Postgres migration open source tool
Thank you all for the responses. All we have is just table migrations, no procedures, triggers involved. I will try to do the migration using ora2pg. I downloaded it, while installing it I am getting an error. Will try to resolve that and proceed Writing /export/home/postgres/perl_5_10_0/lib/perl5/site_perl/5.10.0/sun4-solaris/auto/Ora2Pg/.packlist sh install_all.sh install_all.sh: test: argument expected gmake: *** [install_all] Error 1 Thanks again Regards On Thu, Jul 7, 2011 at 11:51 AM, Lennin Caro lennin.c...@yahoo.com wrote: --- On *Thu, 7/7/11, Craig Ringer cr...@postnewspapers.com.au* wrote: From: Craig Ringer cr...@postnewspapers.com.au Subject: Re: [GENERAL] Oracle to Postgres migration open source tool To: akp geek akpg...@gmail.com Cc: pgsql-general pgsql-general@postgresql.org Date: Thursday, July 7, 2011, 2:02 PM On 7/07/2011 9:55 PM, akp geek wrote: Hi all - Are there any open source tools available for migrating from oracle to postgres.

So you have to bodge up your environment to get the Perl modules installed, then you need to _re_-bodge to make sure you're actually pointing at the actual Oracle installation you want to use.
