The following RDAREAs can be expanded:

• User RDAREAs
• User LOB RDAREAs
• Master directory RDAREA
• Data directory RDAREA
• Data dictionary RDAREAs
• Data dictionary LOB RDAREAs
• Registry RDAREA
• Registry LOB RDAREA
• List RDAREAs

RDAREA expansion should be performed under the following circumstances:

1. The number of rows in a table has increased to the point that no more data can be stored.
2. RDAREA reinitialization cannot be used to increase the size of the RDAREA (for details on RDAREA reinitialization, see 15.4 Modifying the size or attributes of an RDAREA (RDAREA reinitialization)).
3. The RDAREA can contain multiple HiRDB files.

1. If you increase the number of HiRDB files, keep in mind the value in the pd_max_file_no operand. If the number of all HiRDB files in the RDAREAs exceeds the value in this operand, RDAREAs cannot be added.
2. You must handle the RDAREA's status as expanded below:
   
   • If the RDAREA is in error shutdown status, eliminate the cause of the error shutdown, and then use the pdrels command to release the error shutdown status.
   • If the RDAREA is in closed status, use the pdopen command to place it in open status.
