please could you add note about configuration value @@textsize for Sybase database into DB configuration guide section of the Admin Guide.
Possible issue with this configuration value and workaround are described in
Here is small description:
Text and image values stored in the database can be quite large. When a select list includes text and image values, the limit on the length of the data returned depends on the setting of the @@textsize global variable. The default setting for @@textsize depends on the software you use to access Adaptive Server; the default value is 32K for JDBC driver.
