Re: [JDBC] BUG #1026: org.apache.commons.dbcp.DbcpException:

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 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
