| Lorsque Solr démarre, il efface les logs existants de la JVM ($SOLR_LOGS_DIR/solr_gc*). | |
| Lors d'un plantage, on relance généralement Solr sans sauver les logs. | |
| Pour une analyse de problèmes de stabilité et de performances, Il est nécessaire de conserver ces logs | |
| après redémarrage pour une durée de 7 jours. | |
| Pour cela, il est possible de modifier le script de configuration solr.in.sh afin d'y ajouter à la fin | |
| les lignes suivantes. Ces lignes procèdent à un archivage de logs avant effacement et à une purge | |
| des archives de plus de 7 jours. | |
| if [ "x$1" = "xstart" ]; then |
