Actions to take when the number of extents reaches the maximum value

If the number of extents reaches the maximum value (24), automatic extension can no longer be performed. If this happens, take one of the following actions:

Consolidate HiRDB file system area extents.
Reinitialize RDAREAs.
Expand RDAREAs as described in section 15.7.3.

Use either method 1 or method 3 if multiple RDAREAs are assigned to a single HiRDB file system area.

Organization of this subsection: (1) Consolidate HiRDB file system area extents; (2) Reinitialize RDAREAs

(1) Consolidate HiRDB file system area extents

The following procedure shows how to consolidate extents (how to merge all extents into one):

Procedure

Use the pdstop command to terminate HiRDB normally.
Use the pdfbkup command to back up the HiRDB file system area.
Use the pdfmkfs command to reinitialize the HiRDB file system area.
Use the pdfrstr command to recover the HiRDB file system area. Recover using the backup made in step 1.
Use the pdstart command to start HiRDB normally.

(2) Reinitialize RDAREAs

Reinitialize the RDAREAs. For details about how to reinitialize RDAREAs, see 15.4 Increasing the size of an RDAREA or modifying its attributes (RDAREA reinitialization). If you specify the initialize rdarea statement of the pdmod command, however, take note of the following cautions:

Specify the with reconstruction operand.
Specify the number of segments required in the initial statement.

If you do not specify these operands, the RDAREAs will be re-created at the same sizes they were when defined originally.
