Setting Data Object Broker Parameters

Data Object Broker parameters are initially set at installation. You change these defaults by editing the crparm file. The crparm file is located in the install_path/database directory (install_path is stored in the HURON environment variable). You can edit the crparm file by using:

•	A text editor, as described in Changing Parameters in the crparm File

•	The TIBCO Object Service Broker Database Administrator tool, as described in The TIBCO Object Service Broker Database Administrator Tool

You can change some parameter values dynamically by issuing an TIBCO Object Service Broker operator command. For more detail, refer to Dynamically Modifying the Parameters.

Sample Entries

The following shows a sample set of entries in a crparm file:

NODENAME = A

PEERS = (B, 9, 10, WN2)

PEERS = (C, 10, 10, WN3, 2)

MAXDBMS = 0        # Maximum number of DBMS servers (0 to 4096)

MAXUSERS = 32      # Maximum number of seated users (1 to 4096)

MAXOPERATORS = 2   # Maximum number of operators (1 to 64)

Changing Parameters in the crparm File

To override the default parameter settings in the crparm file:

1.	If the Data Object Broker is running, shut it down.

2.	Open the file in a text editor.

You should copy the line containing the parameter you want to change.

3.	Remove the leading comment character (#).

4.	Change the value.

Access Control Parameters

The ability to start, stop, and manage a running Data Object Broker is restricted to certain users, specified through the following Data Object Broker parameters: OPERATOR, PRIVILEGED, SYSADMIN.

These users are classified and identified as follows:

 

Operator	You can specify one or more operators in one or more OPERATOR parameters.
Privileged	You can specify one or more privileged users in one or more PRIVILEGED parameters.
System administrator	You must specify only one user to be the TIBCO Object Service Broker system administrator with the SYSADMIN parameter.

All other users are considered general users.
