Problem:

there seems to be a 16mb size limits to files attached to ELN. can you tell us where we can increase the file size limit?


Solution:

Experiment size limitation is 12MB by default. This value can be modified by a DBA according to your needs. It is defined in the DOCUMENT_CELL.SAVE Oracle package procedure.

IF (totalSize > 16 * 1024 * 1024 ) THEN

RAISE_APPLICATION_ERROR(-20000, 'the total size for documents in this collection (' || (totalSize * 3 / 4) || ') is greater than 12MB');

END IF;

This limit is “cumulative”, which means that all the “document sections” (Excel, Word, PPoint, PDF) in a given experiment jointly cannot exceed 12Mb. There is also some practical limit related to the files included in the in the Ancillary data section. The practical limit for this is in the 20-30Mb range.

There are good reasons why NOT to include huge files in the database. Performance is one of them. Supplementary Data Management module was designed to accommodate large files.
