When a space shortage occurs in an RDAREA, segments can be added automatically to increase the size of the RDAREA, provided that space is available in the HiRDB file system area. This is called RDAREA automatic extension. For details about the RDAREA automatic extension, see 15.8 RDAREA automatic extension.

Note that stopping job tasks is not necessary for extending RDAREAs automatically.

There is a limit to the number of times RDAREA automatic extension explained in (1) above can be performed. When automatic extension is no longer possible, you can expand the RDAREA manually. For details about RDAREA expansion, see 15.3 Increasing the size of an RDAREA (RDAREA expansion).

A maximum of 16 HiRDB files comprise an RDAREA, so no more than 16 HiRDB files can be added to an RDAREA.

Stopping job tasks is not necessary in order to expand an RDAREA.

There is a limit to the number of times RDAREA expansion explained in (2) above can be performed. When expansion is no longer possible, you can reinitialize the RDAREA and increase its size. For details about how to reinitialize RDAREAs, see 15.4 Modifying the size or attributes of an RDAREA (RDAREA reinitialization).

Note that an RDAREA that is being reinitialized cannot be accessed. Therefore, you should us method (1) or (2) above whenever possible.
