PC running slow?
I am very good at using PDI with MySQL. But I want to get some data back to Postgres. It is installed and working properly. With the TableOutput transform, I can connect to Postgres and also find tables. But when I try to run the conversion, I follow the messages in debug mode:
Entry.0 table – Connected to database …
Output of table 0 2) ERROR (version 3.0.0-RC1, build 299003 dated 01.10.2007 23:14:52). … … An error occurred in this initialization loop:
Table output.0 – ERROR (version 3.0.0-RC1, added from 299003 2007/10/01 23:14:52): An error occurred while trying to connect to all databases
Table output 0 – ERROR (Version 3.0.0-RC1, extension 299003 from 23:14:52) 01/10/2007:

Since I am an index type and not a Java type, I will consider all the details. Many thanks.
I am using PostgreSQL 9.1 and now I am using the Pentaho Designer report to generate reports generated from a datastore stored in a repository. This database is named bd-datawarehouse .
I have a problem when I try to connect from the Pentaho Report Designer to the bd-datawarehouse database. I’ve tweaked everything you see settings and everything looks fine like the following image:
but when I usually click the Test button, I get the following error:

You should be aware that all parameter fields can be correct (database name, port number, usernamehost name, username and password).
Seeing the nature of the error, I thought the problem might be that I don’t have a jdbc driver to help you connect to the PostgreSQL database. The answer to this question was this: I downloaded the driver for my postgresql 9.2 from here and placed the element in ... biserver-ce tomcat lib , but the problem persists.
I don’t know how to fix this because I don’t really understand what the problem is.
