Errors and SOLUTIONs for Alfresco installation

Hi.
      Alfresco uses log4j for logging. When u install and use Alfresco u can see errors, warn, debug and etc. in alfresco.log file.

In Linux u can follow errors as: tail -f /opt/usr/local/apache/tomcat/logs/catalina.out

In Windows u can do this by any log tail programs. Personally I am using WinTail :)

U can configure your logging settings in file log4j.properties in directory  <tomcat_webapps_dir>/alfresco/WEB-INF/classes

1. ERROR: [domain.schema.SchemaBootstrap] Schema auto-update failed org.alfresco.error.AlfrescoRuntimeException: A previous schema upgrade failed. Revert to the original database before attempting the upgrade again.
SOLUTION: Delete "alf_bootstrap_lock" table from DB and try again
