Un petite question posée par mail il y a peu:

Pour lister les jobs

SQL> connect system/xxx
SQL> select job, schema_user, next_date, what from dba_jobs;

JOB    SCHEMA_USER    NEXT_DATE     WHAT
------ -------------- ---------     --------------------
1      SYSMAN         19-OCT-08     EMD_MAINTENANCE.EXECUTE_EM_DBMS_JOB_PROCS();
100    CRM            19-OCT-08     CRM_PROCS();
101    STAT           19-OCT-08     STAT_JOB_PROCS();

Pour supprimer un job

SQL> exec dbms_job.remove(215);
PL/SQL procedure successfully completed.

Nagios – demarrage & arret

On March 30, 2008   /   Linux, Nagios, Shell, Supervision   /   Leave a comment

>>> I. Test et verification

Nagios adopte une configuration modulaire, il n’est pas rare d’oublier le definition d’un contact, oublier une parenthese,….
Pour tester votre configuration actuelle de Nagios executer /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

Voici le resultat:

$/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

Nagios 2.9

Things look okay – No serious problems were detected during the pre-flight check

J’ai volontairement laissé de “petites” erreurs dans la configuration, ces dernieres sont sans conséquences pour le bon fonctionnement de Nagios, il s’agit de Warning. Nagios pourra etre lancé.

Si nous avions eu une erreur, par exemple

$/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

Reading configuration data…

Error: Could not find any host matching ‘Serveur_99′
Error: Could not expand hostgroups and/or hosts specified in service (config file ‘/usr/local/nagios/etc/services.cfg’, starting on line 12)

***> One or more problems was encountered while processing the config files…

Check your configuration file(s) to ensure that they contain valid
directives and data defintions.  If you are upgrading from a previous
version of Nagios, you should be aware that some variables/definitions
may have been removed or modified in this version.  Make sure to read
the HTML documentation regarding the config files, as well as the
‘Whats New’ section to find out what has changed.

J’ai volontairement defini un service avec un serveur qui n’etait pas defini, ce qui explique l’erreur ci dessus.
Il faut donc corriger toutes les erreurs, nous pourrons ensuite demarrer nagios

>>> II. Lancement

# Lacement classique (foreground process)
$ /usr/local/nagios/bin/nagios /usr/local/nagios/etc/nagios.cfg
> pour l’arret un CTRL+C suffit

To stop Nagios at any time, just press CTRL-C. If you’ve enabled the debugging options you’ll probably want to redirect the output to a file for easier review later.

# Lancement silencieux (Background Process)
$ /usr/local/nagios/bin/nagios /usr/local/nagios/etc/nagios.cfg &

# Lancement en tant que Daemon
$ /usr/local/nagios/bin/nagios -d /usr/local/nagios/etc/nagios.cfg

Ces differentes methodes sont utiles sur des plateformes de test ou sur un pc pour tester le produit, en fonctionnement de production, il faudra adapter le choix suivant.

# Start Nagios
$ /etc/rc.d/init.d/nagios start

# Stop Nagios (tue le process lancé par nagios start)
$ /etc/rc.d/init.d/nagios stop

# Restart Nagios (=nagios stop puis nagios start)
$ /etc/rc.d/init.d/nagios restart

# Reload Configuration Data (envois un SIGHUP au process Nagios, forcant une prise en compte immédiate des nouveaux fichiers de configuration, l’avantage est de ne pas couper le process, par exemple an cas d’ajout d’un serveur ou d’un service)
$ /etc/rc.d/init.d/nagios reload

Fedora 8

On November 14, 2007   /   Linux, News   /   Leave a comment

La derniere version de Fedora est sortie le 8 novembre. Originalité de cette version, en plus de la version “full” traditionnelle, elle se présente sous trois angles différents:

- Fedora Games Spin : un Live DVD rempli de jeux 2D et 3D (Nexuiz, Quake, Freeciv, Nethack …)
- Fedora Developer Spin : un Live DVD qui contient seulement des programmes de développement (Eclipse, Anjuta, git, cvs, lynx, emacs, éditeur hexadécimal … )
- Fedora Electronics Lab : cette version est destinée aux personnes qui souhaitent utiliser des programmes de simulation de systèmes électroniques

La petite particularite qui m’interesse personnellement et l’amalioration de la prise en charge du wifi. NetworkManager 0.7 a été réécrit pour gagner en stabilité et en flexibilité. Celui-ci devrait assurer une plus grande rapidité de connexion, une meilleure intégration grâce à l’API Dbus et au WPA pour le wifi. (il était temps)
