The sample shell scripts provided are summarized below. These scripts are stored in the "/etc/opt/FJSVswsts/samp" directory.
No. | Type | Script Name | Associated Transaction | Associated Resource Type |
|---|---|---|---|---|
1 | Collection of DB information | swst_or_iv | Oracle transaction | - |
2 | Backup | swst_or_vg_bk | Oracle transaction | Raw device |
Note
When a database exists on a file system, backup cannot be performed if the database is in use.
swst_or_iv outputs the Oracle database information. The output file names and their contents are:
spdata.lst: List of table space names and storage destinations
spdata.bgn: Command in the following format
Alter tablespace Table-space-name begin backup;
spdata.end: Command in the following format
Alter tablespace Table-space-name end backup;
spcont.lst: Oracle database control file information
splog.lst: Oracle database log file information
spredolog.lst: REDO Log file information of an Oracle database
Use the database information above as a reference for creating shell scripts for backup processing.

exit 0Overview
swst_or_vg_bk, run using AdvancedCopy Manager, backs up live data using an Oracle database on a raw device.
Live data is copied to work disks prepared by users.
These scripts correspond to steps 2 to 4 in "B.1.1 Backup Procedure".
Format
swst_or_vg_bk {-a | -i} volumeGroupNameOptions
Specify when an Oracle database is online. The start of backup processing is declared to the Oracle server.
Specify when an Oracle database is stopped or the file is a general file. The start of backup processing is not declared to the Oracle server.
Operands
Specify the name of the volume group targeted for backup.
Example of Using swst_or_vg_bk
While processing is active, back up "/dev/vg01" in which an Oracle database is located.
# swst_or_vg_bk -a /dev/vg01 swst_or_vg_bk completed. (/dev/vg01 -> /dev/vg02 at 23:01 on 2005.10.01 )
