Command Parameters

variable= value

Sets a specified variable to a specified value. To delete a variable, do not specify a value for the specified variable. Changes to settings take effect after the instance has been restarted.

-g

Accesses the global profile variables.

-i

Specifies the instance profile to use instead of the current, or default.

node-number

Specifies a number listed in the db2nodes.cfg file.

-all

Displays all occurrences of the local environment variables as defined in:

The environment, denoted by [e]
The node level registry, denoted by [n]
The instance level registry, denoted by [i]
The global level registry, denoted by [g].

-null

Sets the value of the variable at the specified registry level to NULL. This avoids having to look up the value in the next registry level, as defined by the search order.

-r instance

Resets the profile registry for the given instance.

-n DAS node

Specifies the remote DB2 administration server node name.

-u user

Specifies the user ID to use for the administration server attachment.

-p password

-lr

Lists all supported registry variables.

-v

Specifies verbose mode.

-h/-?

Displays help information. When this option is specified, all other options are ignored, and only the help information is displayed.

Examples

Display all defined profiles (DB2 instances):
```
   db2set -l
```
Display all supported registry variables:
```
   db2set -lr
```
Display all defined global variables:
```
   db2set -g
```
Display all defined variables for the current instance:
```
   db2set
```
Display all defined values for the current instance:
```
   db2set -all
```
Display all defined values for DB2COMM for the current instance:
```
   db2set -all DB2COMM
```
Reset all defined variables for the instance INST on node 3:
```
   db2set -r -i INST 3
```
Unset the variable DB2CHKPTR on the remote instance RMTINST through the DAS node RMTDAS using user ID MYID and password MYPASSWD:
```
   db2set -i RMTINST -n RMTDAS -u MYID -p MYPASSWD DB2CHKPTR=
```
Set the variable DB2COMM to be TCPIP,IPXSPX,NETBIOS globally:
```
   db2set -g DB2COMM=TCPIP,IPXSPX,NETBIOS
```
Set the variable DB2COMM to be only TCPIP for instance MYINST:
```
   db2set -i MYINST DB2COMM=TCPIP
```
Set the variable DB2COMM to null at the given instance level:
```
   db2set -null DB2COMM
```

Usage Notes

If no variable name is specified, the values of all defined variables are displayed. If a variable name is specified, only the value of that variable is displayed. To display all the defined values of a variable, specify variable -all. To display all the defined variables in all registries, specify -all.

To modify the value of a variable, specify variable=, followed by its new value. To set the value of a variable to NULL, specify variable -null.
Note: Changes to settings take effect after the instance has been restarted.

To delete a variable, specify variable=, followed by no value.
