Logging
The logging configuration file is located in the same place as the distributed alexandria.xml, e.g.,
| Code Block |
|---|
/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.
| Code Block |
|---|
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:
- http://search.cpan.org/~mschilli/Log-Log4perl-1.49/lib/Log/Log4perl.pm
- http://search.cpan.org/~mschilli/Log-Log4perl-1.49/lib/Log/Log4perl.pm#Configuration_files
Credentials
There are two sets of credentials:
- --IFIuser/--IFIpassword passed to apgupd – issued by IFI CLAIMS
- --PGSuser/--PGSpassword used to connect to postgresql – created during the PostgreSQL database installation
apgupd requires the IFIuser / IFIpassword, e.g.,
| Code Block |
|---|
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.,
| Code Block |
|---|
$ 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:
- alexandria (http://127.0.0.1:8080/alexandria-v1.5):
- alexandria-dummy (http://127.0.0.1:8080/alexandria-index):
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
| Code Block |
|---|
<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.
