To enable the federation of new documents, you must create a default map for each IBM® FileNet® Image Services document class from which you want to federate documents. To federate documents that existed before the default mapping was created, you must export the documents to Content Platform Engine.
The index properties that are exported from IBM FileNet Image Services to Content Platform Engine are sent in the form of a document index record. Each document index record contains the index properties for a single document.
The maximum supported document index record data size is 1988 bytes. This data size represents the sum of all index data with an extra 4 bytes of overhead for each index column. The document index record limit does not apply to the actual table size, but rather to the data that is stored in the columns. For example, a string index can be defined as 239 bytes in size (varchar 239, for example). However, it might never hold more than 10 bytes. This index would be counted as 14, including the 4 more overhead bytes.
The database administrator can examine the layout of DOCTABA index table and determine the sizes based on the data that is stored in the index columns.
