Error «Update home dependency failed» desplegando agentes del oem12c

Posted on por

Tras un periodo demasiado largo sin publicar , vamos a ver la solución a un problema muy sencillo, pero que nos puede traer de cabeza.

Llevando a cabo la instalación del agente para unix (AIX 64) del Enterprise Manager12c, me he encontrado con el error

Update home dependency failed.

Si buscamos en los foros de soporte e oracle o en el propio metalink,encontraremos que es un error que puede deberse a bastantes casos, sin embargo, hay una causa que ( en mi caso era la razón) es muy sencilla de comprobar, y que puede ser la causa principal del error.


If the warning from the installer is bypassed, failure of the console to effectively deploy an agent can be just one of the resulting symptoms.
Unpublished BUG OMS CONFIG FAILING IF SWAP SPACE IS LESS THAN 6GB

Así que, ante este tipo de error , lo mas rápido, sencillo e inmediato es comprobar si tenemos al menos 6 Gb de swap space, es un requisito no publicado que hace que falle la instalacion.
