Cómo resolver ORA-32021: parameter value longer than 255 characters ?

Si tienes problemas a la hora de configurar o cambiar el valor de un parámetro en un base de datos utilizando SPFILE, cuando el valor requerido supera los 255 caracteres; aquí tienes la solución.

Separa la hilera que debe ser ingresada, en porciones menores a los 255 caracteres concatenando los valores con ','

Una vez hecho esto, no tendrás problemas a la hora de setear el valor.

Mira el ejemplo de a continuación.

/opt/oracle/product/11.2.0.4/rdbms/admin
[oracle@lab1 admin]$ /opt/oracle/product/11.2.0.4/rdbms/admin
-bash: /opt/oracle/product/11.2.0.4/rdbms/admin: is a directory
[oracle@lab1 admin]$ sqlplus /nolog
