DB2 10.5 for Linux, UNIX, and Windows

Some registry and environment variables are discontinued

There are a number of registry variables that are discontinued in Version 10.5. You should remove all references to them.

Details

The following registry and environment variables are discontinued in Version 10.5:

Table 1. Registry variables discontinued in Version 10.5
Registry or environment variable	Details
DB2_INDEX_FREE	This registry variable provided the same functionality as the PCTFREE clause in a CREATE INDEX statement. The difference is that DB2_INDEX_FREE applies to all indexes that you create and the PCTFREE clause applies to one index. For more details, see CREATE INDEX statement. Setting this registry variable results in an error because the associated functionality is no longer available.
DB2_TRUSTED_BINDIN	This variable is discontinued because it is no longer supported for improving the performance of query statements containing host variables within an embedded unfenced stored procedure.

Resolution

Remove the use of registry variables that are discontinued as they do not have the intended effect. If a replacement registry variable is indicated in Table 1, set it to the proper value to maintain wanted database manager behavior.
