We've encountered a problem with corrupt bitmap indexes on partitioned tables in Oracles 8.1.7.4. With Oracle's help we're making progress towards a solution, which appears to involve something called a 'Haken Factor'. <br />

I gather this is an attribute of a table which is involved in sizing bitmap indexes, it appears in the SPARE1 column of sys.tab$.<br />

Does anyone know anything about the Haken Factor, Metalink has quite a few references, Google almost nothing relevant. I can see that it's important, but I'm looking for a better explanation of what it is.<br />

What is the Haken Factor?

Oracle is an object-relational database management system. It supports a large number of languages and application development frameworks. Its primary languages are SQL, PL/SQL and Java, but it also includes support for C and C++. Oracle also has its own enterprise modules and application server software.
