Error de consistencia en Online 5.10

Posted By: Mariano Draghi
Date: Tuesday, 3 February 2004, at 8:18 a.m.

Hola amigos.
Tengo un problema un tanto serio en una sucursal un tanto alejada
(fisicamente) de nosotros. Resulta que el DBA de dicha sucursal está de
vacaciones, y el personal que quedó a cargo de los backups y demás
tareas de mantenimiento no está muy entrenado.
Durante el fin de semana, se llenaron los Logical Logs, y como no podían
operar, decidieron reiniciar el servidor.

A partir de allí, el motor está constantemente indicando fallas de
consistencia.

Estoy un tanto desesperado.
Aparentemente se ha dañado una tabla, y cualquier operacion que quiero
realizar sobre ella (incluso los comandos tbcheck -cD o -cI) indican que
el tblspace correspondiente no existe.
He intentado hacer un DROP, pero me aparece el mismo error (tblspace
does not exist)

A continuación les adjunto un extracto del log, donde aparece el error
por primera vez. Quisiera saber si alguno tiene alguna idea de como
resolver este problema, sin recurrir a un backup. Es que si bien hay un
backup hecho, al no haber sido realizado por gente idonea, preferiria
dejarlo como última alternativa... no vaya a ser que también realizaron
mal el Archive.

Este es un extracto del online.log:
