Problem in NGL Desktop

[ashoksatapathy]

Namaskar Team,

I have been installed the new version i.e. 3.1.1 successfully. Configured NGL Clint and Workbench successfully. Enter the bibliographical records and create patron without any problem.

I found problem in NGL Desktop. When I try to run NGL Desktop it shows "Database connection error. Database is not connecting properly please check". Please help me in this regard.

Go to C:/NGL3/apache-tomcat-6.0.32/webapps/desktop/NewGenLibDesktopFiles/SystemFiles
Open postgres-ds.xml with wordpad

If you find something like this
jdbc:postgresql://localhost:5432/SIT

Change it to
jdbc:postgresql://<ServerIP>:5432/SIT

Did you already edit your
postgresql.conf and
pg_hba.conf files?

# PostgreSQL Client Authentication Configuration File
# ===================================================
#
# Refer to the "Client Authentication" section in the
# PostgreSQL documentation for a complete description
# of this file.  A short synopsis follows.
#
# This file controls: which hosts are allowed to connect, how clients
# are authenticated, which PostgreSQL user names they can use, which
# databases they can access.  Records take one of these forms:
#
# local      DATABASE  USER  METHOD  [OPTION]
# host       DATABASE  USER  CIDR-ADDRESS  METHOD  [OPTION]
# hostssl    DATABASE  USER  CIDR-ADDRESS  METHOD  [OPTION]
# hostnossl  DATABASE  USER  CIDR-ADDRESS  METHOD  [OPTION]
#
# (The uppercase items must be replaced by actual values.)
#
# The first field is the connection type: "local" is a Unix-domain socket,
# "host" is either a plain or SSL-encrypted TCP/IP socket, "hostssl" is an
# SSL-encrypted TCP/IP socket, and "hostnossl" is a plain TCP/IP socket.
#
# DATABASE can be "all", "sameuser", "samerole", a database name, or
# a comma-separated list thereof.
#
# USER can be "all", a user name, a group name prefixed with "+", or
# a comma-separated list thereof.  In both the DATABASE and USER fields
# you can also write a file name prefixed with "@" to include names from
# a separate file.
#
# CIDR-ADDRESS specifies the set of hosts the record matches.
# It is made up of an IP address and a CIDR mask that is an integer
# (between 0 and 32 (IPv4) or 128 (IPv6) inclusive) that specifies
# the number of significant bits in the mask.  Alternatively, you can write
# an IP address and netmask in separate columns to specify the set of hosts.
#
# METHOD can be "trust", "reject", "md5", "crypt", "password", "gss", "sspi",
# "krb5", "ident", "pam" or "ldap".  Note that "password" sends passwords
# in clear text; "md5" is preferred since it sends encrypted passwords.
#
# OPTION is the ident map or the name of the PAM service, depending on METHOD.
#
# Database and user names containing spaces, commas, quotes and other special
# characters must be quoted. Quoting one of the keywords "all", "sameuser" or
# "samerole" makes the name lose its special character, and just match a
# database or username with that name.
#
# This file is read on server startup and when the postmaster receives
# a SIGHUP signal.  If you edit the file on a running system, you have
# to SIGHUP the postmaster for the changes to take effect.  You can use
# "pg_ctl reload" to do that.

# Put your actual configuration here
# ----------------------------------
#
# If you want to allow non-local connections, you need to add more
# "host" records. In that case you will also need to make PostgreSQL listen
# on a non-local interface via the listen_addresses configuration parameter,
# or via the -i or -h command line switches.
#



# TYPE  DATABASE    USER        CIDR-ADDRESS          METHOD

# IPv4 local connections:
host    all         all         127.0.0.1/32          md5
# IPv6 local connections:
host    all         all         ::1/128               md5

postgresql.conf

# -----------------------------
# PostgreSQL configuration file
# -----------------------------
#
# This file consists of lines of the form:
#
#   name = value
#
# (The "=" is optional.)  Whitespace may be used.  Comments are introduced with
# "#" anywhere on a line.  The complete list of parameter names and allowed
# values can be found in the PostgreSQL documentation.
#
# The commented-out settings shown in this file represent the default values.
# Re-commenting a setting is NOT sufficient to revert it to the default value;
# you need to reload the server.
#
# This file is read on server startup and when the server receives a SIGHUP
# signal.  If you edit the file on a running system, you have to SIGHUP the
# server for the changes to take effect, or use "pg_ctl reload".  Some
# parameters, which are marked below, require a server shutdown and restart to
# take effect.
#
# Any parameter can also be given as a command-line option to the server, e.g.,
# "postgres -c log_connections=on".  Some paramters can be changed at run time
# with the "SET" SQL command.
#

Your postgresql.conf is fine

But see the last few lines of pg_hba.conf. You will find this line

host    all         all         127.0.0.1/32          md5

Replace the above line with
host    all         all         0.0.0.0/0          trust




Restart postgresql service

Thanks team,
I am attaching herewith both the script for your necessary observation. Please guide me. If modification is require then do the same and inform me. I will work as per your instruction.

# PostgreSQL Client Authentication Configuration File
# ===================================================
#
# Refer to the "Client Authentication" section in the
# PostgreSQL documentation for a complete description
# of this file.  A short synopsis follows.
#
# This file controls: which hosts are allowed to connect, how clients
# are authenticated, which PostgreSQL user names they can use, which
# databases they can access.  Records take one of these forms:
#
# local      DATABASE  USER  METHOD  [OPTION]
# host       DATABASE  USER  CIDR-ADDRESS  METHOD  [OPTION]
# hostssl    DATABASE  USER  CIDR-ADDRESS  METHOD  [OPTION]
# hostnossl  DATABASE  USER  CIDR-ADDRESS  METHOD  [OPTION]
#
# (The uppercase items must be replaced by actual values.)
#
# The first field is the connection type: "local" is a Unix-domain socket,
# "host" is either a plain or SSL-encrypted TCP/IP socket, "hostssl" is an
# SSL-encrypted TCP/IP socket, and "hostnossl" is a plain TCP/IP socket.
#
# DATABASE can be "all", "sameuser", "samerole", a database name, or
# a comma-separated list thereof.
#
# USER can be "all", a user name, a group name prefixed with "+", or
# a comma-separated list thereof.  In both the DATABASE and USER fields
# you can also write a file name prefixed with "@" to include names from
# a separate file.
#
# CIDR-ADDRESS specifies the set of hosts the record matches.
# It is made up of an IP address and a CIDR mask that is an integer
# (between 0 and 32 (IPv4) or 128 (IPv6) inclusive) that specifies
# the number of significant bits in the mask.  Alternatively, you can write
# an IP address and netmask in separate columns to specify the set of hosts.
#
# METHOD can be "trust", "reject", "md5", "crypt", "password", "gss", "sspi",
# "krb5", "ident", "pam" or "ldap".  Note that "password" sends passwords
# in clear text; "md5" is preferred since it sends encrypted passwords.
#
# OPTION is the ident map or the name of the PAM service, depending on METHOD.
#
# Database and user names containing spaces, commas, quotes and other special
# characters must be quoted. Quoting one of the keywords "all", "sameuser" or
# "samerole" makes the name lose its special character, and just match a
# database or username with that name.
#
# This file is read on server startup and when the postmaster receives
# a SIGHUP signal.  If you edit the file on a running system, you have
# to SIGHUP the postmaster for the changes to take effect.  You can use
# "pg_ctl reload" to do that.

# Put your actual configuration here
# ----------------------------------
#
# If you want to allow non-local connections, you need to add more
# "host" records. In that case you will also need to make PostgreSQL listen
# on a non-local interface via the listen_addresses configuration parameter,
# or via the -i or -h command line switches.
#



# TYPE  DATABASE    USER        CIDR-ADDRESS          METHOD

# IPv4 local connections:
host    all         all         127.0.0.1/32          md5
# IPv6 local connections:
host    all         all         ::1/128               md5

# -----------------------------
# PostgreSQL configuration file
# -----------------------------
#
# This file consists of lines of the form:
#
#   name = value
#
# (The "=" is optional.)  Whitespace may be used.  Comments are introduced with
# "#" anywhere on a line.  The complete list of parameter names and allowed
# values can be found in the PostgreSQL documentation.
#
# The commented-out settings shown in this file represent the default values.
# Re-commenting a setting is NOT sufficient to revert it to the default value;
# you need to reload the server.
#
# This file is read on server startup and when the server receives a SIGHUP
# signal.  If you edit the file on a running system, you have to SIGHUP the
# server for the changes to take effect, or use "pg_ctl reload".  Some
# parameters, which are marked below, require a server shutdown and restart to
# take effect.
#
# Any parameter can also be given as a command-line option to the server, e.g.,
# "postgres -c log_connections=on".  Some paramters can be changed at run time
# with the "SET" SQL command.

Thanks Sir,

I can't modify the script as you suggested. When I want to save the file after modification it shows "Access to C:\programme files (X86)\PostgreSQL\8.3\data\pg_config was denied"

Please suggest what to do?

[Verus Open Source Support]

Copy the file to the deskop and make changes and save
Now copy the edited file back to its location replacing the old file as an Administrator
