Note:

  • For remote installations which include both PostgreSQL and Solr, we recommend a minimum of two server machines.
  • We highly recommend that you select the disk subsystem (hardware raid, software raid, LVM or any combination) with support for extending device capacity. New and updated content is continually flowing through CLAIMS Direct, and it is very important that your disk subsystem possesses the capacity for expansion.
  • IFI CLAIMS has produced a patched release of libxml2-2.9.2 as an RPM. We recommend locally installing this package and replacing the package in the distribution. Download the RPM at: http://alexandria.fairviewresearch.com/software/libxml2/f20/libxml2-2.9.2-1.fc20.x86_64.rpm. Contact support@ificlaims.com if other versions are required.

Logging

The logging configuration file is located in the same place as the distributed alexandria.xml, e.g.,

/usr/share/perl5/vendor_perl/auto/share/dist/Alexandria-Library/alexandria-log.conf

If you want to customize logging, copy the distribution alexandria-log.conf file to /etc.

cp /usr/share/perl5/vendor_perl/auto/share/dist/Alexandria-Library/alexandria-log.conf /etc

Modify as desired.

If you make no changes, default logging is output to /tmp/alexandria.log.

For more information about how the alexandria tools log, see:

Credentials

There are two sets of credentials:

  1. --IFIuser/--IFIpassword passed to apgupd – issued by IFI CLAIMS
  2. --PGSuser/--PGSpassword used to connect to postgresql – created during the PostgreSQL database installation

apgupd requires the IFIuser / IFIpassword, e.g.,

apgupd --user=IFIuser --password=IFIpassword

The connection string to postgresql is configurable in the main configuration file alexandria.xml. You can find that configuration file using acfg, e.g.,

$ acfg

Using configuration from: /etc/alexandria.xml

Configured Databases:

  • alexandria: [alexandria; 127.0.0.1; 5432]
  • alexandria-dummy: [alexandria; 127.0.0.1; 5432]

 Configured Indices:

If you used a different user to create and load the alexandria database, you need to modify the database entry in the file pointed to by:

Using configuration from: /etc/alexandria.xml

<database name="alexandria" host="127.0.0.1" port="5432" user="alexandria" password="alexandria">
      <atts pg_errorlevel="0" AutoCommit="1" RaiseError="1" PrintError="0" LongTruncOk="0" LongReadLen="10485760" />
    </database>

Modify @user and @password to the correct values, assuming the defaults are incorrect.
