I enabled logging. The logging results are below with the query results.
I assume that I am running the queries appropriately. The database service had to be started because of copy paste problems, not because of the queries below. Here are the results:What do you get from the results of the following queries when run in psql?

Tammy,
are you building the jar from source? if so can you try running ant test
?

you really should be getting something like

I am building dspace from source, however ant test does not work. I get the following error:
$ ant test
Buildfile: build.xml
BUILD FAILED
Target `test' does not exist in this project.
I tried running the psql commands just like below and still only get SELECT as the response.
Below is a snippit of our installation process that involved postgres. Maybe it'll help shed some light.
$ ant test
Buildfile: build.xml
BUILD FAILED
Target `test' does not exist in this project.
I tried running the psql commands just like below and still only get SELECT as the response.
Below is a snippit of our installation process that involved postgres. Maybe it'll help shed some light.
Notation
Throughout the course of this document we will used the following notation:
[postgres-src] – This is the source from which you will build and install the PostgreSQL database system. We used /usr/local/postgresql-7.3.4.
[postgres] – The directory in which you will/have install(ed) PostgreSQL. We used /usr/local/pgsql.
[postgres-data] – This is the location of the PostgreSQL database, which will then contain the data from DSpace. We used /usr/local/pgsql/data. Note: that this directory must have rwx permissions for the PostgreSQL user.
PostgreSQL
We used 7.3.4.
Pre-requisite Software:
gmake or make: Download the GNU Make binary file, which comes as a .tar.gz compressed file. We located GNU Make at /usr/local/bin/make.
gcc: Download the gcc binary file, which comes as a .tar.gz compressed file. We located gcc at /usr/local/bin/gcc.
readline: Download the readline binary file, which comes as a .tar.gz compressed file. We located readline at /usr/local/bin/readline.
Copy the libreadline library into /usr/lib and /usr/local/lib.
JDBC: Download the JDBC drivers at http://jdbc.postgresql.org/download.html. We located the download at /usr/local/jdbc.
Installation:
Note: DSpace comes packaged with a postgresql.jar file for an older version of PostgreSQL. To make DSpace work with PostgreSQL 7.2.4 it is necessary to replace their version of postgresql.jar with the new one created with this installation.
Note: You require Ant 1.5 in order to build PostgreSQL 7.2.4 using the –-with-java option required to create the drivers for DSpace.
Note: You must do the installation in bourne shell.
· Create a user called postgres and a group of the same name.
· Login as postgres in order to do the installation.
· Configure the source:
Go to the directory [postgres-src], and run the following command:
./configure --prefix=[postgres]
–-enable-multibyte
--enable-unicode
--with-java
· make PostgreSQL:
In [postgres-src] run the command:
make
· Install PostgreSQL:
In [postgres-src] run the command:
make install
· Create the database:
Use the following commands (you may be in any system directory provided that you use the full path names of each directory):
mkdir [postgres-data]
[postgres]/bin/initdb –D [postgres-data]
· Copy the postgresql.jar file
cp [postgres]/share/java [DSpace-src]/lib
· Place the libgcc library in the postgres library
cp libgcc_s.so.1 [postgres]/lib/.
· Copy the JDBC driver jar file to postgres:
cp jdbcDriver.jar [postgres]/share/java/.
· Edit the postgres configuration file, [postgres]/data/postgresql.conf. to switch on the TCP/IP connections and configure the port:
Set the following configuration parameters:
tcpip_socket=true
port=5432
· Set the following environment variables:
PGDATA=[pgsql]/data
PGPORT=5432
· Start the database service:
[postgres]/bin/postmaster –o "-i" -D /usr/local/pgsql/data > logfile 2>&1 &
DSpace Installation
· Create a DSpace user and a group of the same name, containing that user.
· Log in as DSpace.
· Create the DSpace database and user for that database:
Use the following commands in the directory [postgres]/bin:
createuser –U postgres –d –A –P DSpace
createdb –U DSpace DSpace –E UNICODE

Tammy, Sorry, I wasn't clear, ant test is for the jdbc driver. Either way, if you can't get psql to return version then there are problems.

I downloaded the jdbc driver jar which was used by postgres to compile up drivers.
When I ran the queries in psql, I got the same SELECT response.

Tammy, Sorry, I wasn't clear, ant test is for the jdbc driver. Either way, if you can't get psql to return version then there are problems. Does psql work in interactive mode, can you select anything? Dave On Wed, 2003-12-24 at 11:59, Tammy Jones wrote:I am building dspace from source, however ant test does not work. I get the following error: $ ant test Buildfile: build.xml BUILD FAILED Target `test' does not exist in this project. I tried running the psql commands just like below and still only get SELECT as the response. Below is a snippit of our installation process that involved postgres. Maybe it'll help shed some light. Notation Throughout the course of this document we will used the following notation: [postgres-src] – This is the source from which you will build and install the PostgreSQL database system. We used /usr/local/postgresql-7.3.4. [postgres] – The directory in which you will/have install(ed) PostgreSQL. We used /usr/local/pgsql. [postgres-data] – This is the location of the PostgreSQL database, which will then contain the data from DSpace. We used /usr/local/pgsql/data. Note: that this directory must have rwx permissions for the PostgreSQL user. PostgreSQL We used 7.3.4. Pre-requisite Software: gmake or make: Download the GNU Make binary file, which comes as a .tar.gz compressed file. We located GNU Make at /usr/local/bin/make. gcc: Download the gcc binary file, which comes as a .tar.gz compressed file. We located gcc at /usr/local/bin/gcc. readline: Download the readline binary file, which comes as a .tar.gz compressed file. We located readline at /usr/local/bin/readline. Copy the libreadline library into /usr/lib and /usr/local/lib. JDBC: Download the JDBC drivers athttp://jdbc.postgresql.org/download.html. We located the download at /usr/local/jdbc. Installation: Note: DSpace comes packaged with a postgresql.jar file for an older version of PostgreSQL. To make DSpace work with PostgreSQL 7.2.4 it is necessary to replace their version of postgresql.jar with the new one created with this installation. Note: You require Ant 1.5 in order to build PostgreSQL 7.2.4 using the –-with-java option required to create the drivers for DSpace. Note: You must do the installation in bourne shell. · Create a user called postgres and a group of the same name. · Login as postgres in order to do the installation. · Configure the source: Go to the directory [postgres-src], and run the following command: ./configure --prefix=[postgres] –-enable-multibyte --enable-unicode --with-java · make PostgreSQL: In [postgres-src] run the command: make · Install PostgreSQL: In [postgres-src] run the command: make install · Create the database: Use the following commands (you may be in any system directory provided that you use the full path names of each directory): mkdir [postgres-data] [postgres]/bin/initdb –D [postgres-data] · Copy the postgresql.jar file cp [postgres]/share/java [DSpace-src]/lib · Place the libgcc library in the postgres library cp libgcc_s.so.1 [postgres]/lib/. · Copy the JDBC driver jar file to postgres: cp jdbcDriver.jar [postgres]/share/java/. · Edit the postgres configuration file, [postgres]/data/postgresql.conf. to switch on the TCP/IP connections and configure the port: Set the following configuration parameters: tcpip_socket=true port=5432 · Set the following environment variables: PGDATA=[pgsql]/data PGPORT=5432 · Start the database service: [postgres]/bin/postmaster –o "-i" -D /usr/local/pgsql/data > logfile 2>&1 & DSpace Installation · Create a DSpace user and a group of the same name, containing that user. · Log in as DSpace. · Create the DSpace database and user for that database: Use the following commands in the directory [postgres]/bin: createuser –U postgres –d –A –P DSpace createdb –U DSpace DSpace –E UNICODE Dave Cramer wrote:Tammy, are you building the jar from source? if so can you try running ant test ? also see my comments below Dave On Wed, 2003-12-24 at 09:32, Tammy Jones wrote:Kris Jurka wrote:PostgreSQL version: 7.3.4 Description: org.apache.commons.dbcp.DbcpException: The connection attempt failed because failed getting backend We are trying to install DSPACE with POSTGRES.
