Check all the HiRDB files system areas containing the RDAREAs to be initialized.

Assume you determined in step (1) that the HiRDB files system areas have no free space. In order to increase the sizes of the RDAREAs when you reinitialize them, you must use one of the following methods to prepare the HiRDB file system areas:

1. Allocate new HiRDB file system areas that are larger than the existing HiRDB file system areas.
2. Allocate new HiRDB file system areas in addition to the existing HiRDB file system areas.
3. Expand the existing HiRDB file system areas.

This example uses method 1 to prepare a HiRDB file system areas.

pdcopy -m /rdarea/mast/mast01 -M r -a -b /pdcopy/backup01 -p /pdcopy/list01
 

Explanation

-m: Specifies the name of the first HiRDB file in the master directory RDAREA.

-M: Specifies the backup acquisition mode.

-a: Specifies that all RDAREAs are to be backed up. When an RDAREA is reinitialized, other RDAREAs are also updated as explained in 6.3 RDAREAs to be backed up together. Therefore, you must also back up other RDAREAs as shown in section 6.3. In this example, all RDAREAs are backed up.

-b: Specifies the name of the backup file.

-p: Specifies the output destination of the pdcopy command's processing results listing.

For details about making backups, see 6. Backup Procedures.

A control statements file (/pdmod/init01) is created for the initialize rdarea statement of the pdmod command. The following are the contents of the control statements file:

 
initialize rdarea RDAREA2                               1
   with reconstruction                                  2
   file name "/rdarea/area12/files01"                   3
      initial 3000 segments;                            4
initialize rdarea RDAREA3
   with reconstruction
   file name "/rdarea/area13/files01"
      initial 3000 segments;
initialize rdarea RDAREA4
   with reconstruction
   file name "/rdarea/area14/files01"
       initial 3000 segments;
initialize rdarea RDAREA5
   with reconstruction
   file name "/rdarea/area15/files01"
       initial 3000 segments;
 

Explanation

The newly created HiRDB file system area is allocated for the RDAREAs being reinitialized.

1. Specifies the RDAREAs being initialized.
2. Because the file structure is being changed from what it was before reinitialization, specify with reconstruction.
3. Specifies the HiRDB file comprising the RDAREA.
4. Specifies the number of HiRDB file segments.

 
pdmod -a /pdmod/init01
 

Explanation

-a: Specifies the name of the control statements file for the pdmod command created in step (6).

Reference note

When RDAREA2, RDAREA4, and RDAREA5 are reinitialized, the abstract data type with the LOB attribute is denied access to the index, because the index is incomplete. However, reinitializing RDAREA1 in step (10) releases these RDAREAs, so this does not pose a problem.

A control statements file (/pdmod/init02) is created for the initialize rdarea statement of the pdmod command. The following are the contents of the control statements file:

 
initialize rdarea RDAREA1                               1
   with reconstruction                                  2
   file name "/rdarea/area11/file01"                    3
      initial 3000 segments;                            4
 

Explanation

The newly created HiRDB file system area is allocated for RDAREA1.

1. Specifies the RDAREA (RDAREA2) that is to be reinitialized.
2. Because the file structure is being changed from what it was before reinitialization, specify with reconstruction.
3. Specifies the HiRDB file comprising the RDAREA.
4. Specifies the number of HiRDB file segments.

 
pdmod -a /pdmod/init02
 

Explanation

-a: Specifies the name of the control statements file for the pdmod command created in step (9).

Execute the UAP that inserts data into TABLE1 to recover the data.

 
pdcopy -m /rdarea/mast/mast01 -M r -a -b /pdcopy/backup02 -p /pdcopy/list02
 

When an RDAREA is reinitialized, other RDAREAs are also updated as explained in 6.3 RDAREAs to be backed up together. Therefore, you must also back up other RDAREAs as shown in section 6.3. In this example, all RDAREAs are backed up. For details about making backups, see 6. Backup Procedures.

We recommend that after the command has executed you check whether the execution results are correct. For details on how to check command execution results, see the manual HiRDB Version 9 Command Reference.
