(9) Store the unload data file and export files on a medium such as CMT
The unload data file created in step (3) and the export files created in steps (6) and (8) are stored on a medium such as CMT.
The operations at the source system (HiRDB system A) are now completed.
(10) Store the unload data file and export files in target system
The operations from this point on are performed at the target system (HiRDB system B).
The unload data file and export files stored on a medium such as CMT are copied into the target system.
(11) Use the pddef command to define a schema for the user who owns PROC1 and TABLE1
pddef
CREATE SCHEMA AUTHORIZATION USR01;
|
(12) Swap the system log files
Before making a backup copy, use the pdlogswap command to swap the system log files.
- Explanation
- For a HiRDB parallel server configuration, specify the -s option and execute the pdlogswap command on each server that is to be backed up.
(13) Use the pdcopy command to back up data
pdcopy -m /rdarea/mast/mast01 -M r
-r RDMAST,RDDIR,RDDIC,DICLOB,RDAREA1,RDAREA2,RDAREA3,RDAREA4,RDAREA5,
RDAREA6 -b /pdcopy/backup01 -p /pdcopy/list01
|
- Explanation
- The RDAREAs are backed up as a safeguard in the event of errors during database migration. The following RDAREAs must be backed up:
- Master directory RDAREA
- Data directory RDAREA
- Data dictionary RDAREAs
- Data dictionary LOB RDAREAs
- User RDAREAs and user LOB RDAREAs for storing the imported table (RDAREA1 to RDAREA6)
- -m: Specifies the name of the first HiRDB file in the master directory RDAREA.
- -M: Specifies the backup acquisition mode.
- -r: Specifies the names of the RDAREAs to be backed up.
- -b: Specifies the name of the backup file.
- -p: Specifies the output destination for the pdcopy command's processing results listing.
- For details about making backups, see 6. Backup Procedures.
