Example 8: Reorganizing a table in which an abstract data type is defined

This example reorganizes a table (TABLE1) in which an abstract data type (GEOMETRY or XML type) is defined without the LOB attribute. For an example of reorganizing with an abstract data type (SGMLTEXT type) and the LOB attribute, see 13.3.5 Example 5: Reorganizing a table in which a LOB column is defined. The following are the conditions for this reorganization:

TABLE1 is row-partitioned in user RDAREAs (RDAREA1 and RDAREA2)
The table is reorganized in the pre-update log acquisition mode (default).

Note: The data indicated by shading is subject to reorganization.

Procedure

Use the pdhold command to shut down the RDAREAs to be reorganized.
Create a control statements file for the pdrorg command.
Use the pdrorg command to reorganize the table.
Back up the RDAREAs that were reorganized.
Use the pdrels command to release the RDAREAs from shutdown status.

The procedure step numbers correspond to the paragraph numbers in the explanation that follows. For example, step 3 above is explained in paragraph (3) below.

Hint

Because you are using the pdrorg command in the pre-update log acquisition mode, you must make a backup after executing the pdrorg command, as described in step 4.
Because you are using the pdrorg command in the pre-update log acquisition mode, keep the RDAREAs being reorganized in shutdown status from steps 1 through 4.

Organization of this subsection: (1) Use the pdhold command to shut down RDAREAs to be reorganized; (2) Create the control statements file for the pdrorg command; (3) Use the pdrorg command to reorganize the table; (4) Back up the RDAREAs that were reorganized; (5) Use the pdrels command to release RDAREAs from shutdown status

(1) Use the pdhold command to shut down RDAREAs to be reorganized

(2) Create the control statements file for the pdrorg command

The following are the contents of the control statements file (/pdrorg/rorg01):

(a) HiRDB single server configuration

 
unload /pdrorg/unfile1                        1
idxwork /pdrorg/idxwork                       2
sort /sortwork                                3

Explanation

Specifies the name of the unload data file.
Specifies the name of the directory in which an index information file is to be created. The index information file is created under this directory.
Specifies the name of the work directory for sorting.

(b) HiRDB parallel server configuration

 
unload bes1:/pdrorg/unfile1                  1
idxwork bes1 /pdrorg/idxwork                 2
sort bes1 /sortwork                          3
unload bes2:/pdrorg/unfile2                  4
idxwork bes2 /pdrorg/idxwork                 5
sort bes2 /sortwork                          6

Explanation

Specifies the name of the unload data file (for bes1).
Specifies the name of the directory in which an index information file is to be created (for bes1). The index information file is created under this directory.
Specifies the name of the work directory for sorting (for bes1).
Specifies the name of the unload data file (for bes2).
Specifies the name of the directory in which an index information file is to be created (for bes2). The index information file is created under this directory.
Specifies the name of the work directory for sorting (for bes2).

(3) Use the pdrorg command to reorganize the table

 
pdrorg -k rorg -t TABLE1 /pdrorg/rorg01

Explanation: -k: Specifies rorg for reorganization.; -t: Specifies the name of the table that is to be reorganized.; /pdrorg/rorg01: Specifies the name of the control statements file for the pdrorg command created in step (2).

(4) Back up the RDAREAs that were reorganized

(5) Use the pdrels command to release RDAREAs from shutdown status

 
pdrels -r RDAREA1,RDAREA2,RDAREA3,RDAREA4,RDAREA5,RDAREA6

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.
