About Siebel Tables and CLOB Columns

This topic describes how character large object (CLOB) data types are implemented on the z/OS platform.

When you install Siebel CRM, a number of Siebel application objects are defined as CLOB data types in the Siebel Repository; such objects can have up to 128 KB of data for a single data element in a table row. Other Siebel tables have columns that are defined as LONG columns in the Siebel Schema, and as LONG VARCHARs in the Siebel Repository, but are converted to CLOB columns on z/OS. Siebel objects that are defined as LONG columns but stored as CLOBs can have up to 16,350 bytes of data for a single data element in a table row.
