DB2 10.5 for Linux, UNIX, and Windows

Some registry and environment variables are deprecated

There are a number of registry variables that are deprecated in DB2® Version 10.5. Deprecated variables are still available, but you should not use them because they will likely be removed in a future version.

The following table lists deprecated registry and environment variables. They have been replaced by another feature, or the function that they support is obsolete.

Table 1. Registry and environment variables deprecated in Version 10.5
Registry or environment variable	Details
DB2_EVMON_EVENT_LIST_SIZE	Setting this registry variable has no effect because of the changes that were made to the underlying event monitor infrastructure in Version 9.7.
DB2_NCHAR_SUPPORT	This registry variable enables the use of user-defined types called NCHAR, NVARCHAR or NCLOB. These data types are no longer required because all the character length sensitive functions now return the number of characters. Start using the nchar_mapping database configuration parameter to specify the data type mapping for national character string data types in your Unicode databases before this registry variable is discontinued. For more details, see nchar_mapping - National character mapping configuration parameter

Resolution

Start using the replacement feature or function related to the registry variable that is deprecated.

Remove the use of registry variables that are deprecated because the functionality associated with the configuration parameter is obsolete or has been replaced by new functionality.
