Parameters for DB2 Storagegroups

Common parameters which are not included in the table below are described under Common Parameters for All DB2 Types.

Parameters
Selection criteria
Storagespace ID ID of the Predict storagespace object to be compared with a DB2 storagegroup. Asterisk notation can be used
List option
Storagespace attributes
How attributes of the Predict storagespace object are to be displayed.
Y All attributes are listed.
N No attributes are listed.
D Different: only attributes of storagespace that are different from the storagegroup are listed.
Update option
Storagespace attributes
Y Attributes of the Predict storagespace that differ from the DB2 storagegroup are updated.

Comparing DB2 Storagegroups in Batch Mode

Command: COMPARE STORAGEGROUP

Enter parameters on the next line in positional or keyword form.

Field Keyword Position
Storagespace ID STOSPACE-ID 1
List option
Storagespace attributes LIST-ST 2
Update options
Storagespace attributes UPD-ST 3
SQL Server SQL-SERVER 4

If you explicitly set SQL-SERVER to blank in order to use the default server, another keyword must be specified after the SQL-SERVER keyword. If it is not possible to specify another keyword, the SQL-SERVER keyword must be followed by "D1=*" as shown below: 

SQL-SERVER= ,D1=*

Example

To compare all storagespaces with prefix "TEST" and list all attributes, code the command: 

COMPARE STORAGEGROUP
STOSPACE-ID=TEST*,LIST-ST=Y

or

COMPARE STORAGEGROUP
TEST*,Y

The example above uses the Natural parameter ID=, and IA==.
