Setting the maximum column length
The default maximum column length Actuate uses with Oracle data sources is 4000 characters. Problems can occur when generating an Actuate document if the design uses an Oracle data source column with a large column length. You can use a registry setting on Windows or an environment variable on Linux to set a smaller maximum column length used by Actuate.
To change the maximum character length:
On Windows, change the value of the string value name MaxVarLen. The value name is in the registry key.
HKEY_CURRENT_USER\Software\Actuate\DBMS\Oracle
On Linux, set the environment variable AC_DBMS_ORACLE_MAXVARLEN.
