Configuring DB2 UDB EEE
The DB2 UDB EEE component uses TCP/IP sockets to communicate between hosts defined in the DB2 db2nodes.cfg file. To set up TCP/IP communication for PATROL for DB2 UDB, you must define the default port service name and the default ports that PATROL will use.
The following tasks assign a service name and a set of port numbers for the KM to use to communicate with the DB2 nodes in a multi-partitioned system. In a UNIX system, a port entry is created in the /etc/services file from the information provided in this command. In a Windows NT system, the entry is created in c:\WINNT\SYSTEM32\DRIVERS\etc\services.
Enable and disable capability in the rsh and ssh environments
PATROL for DB2 UDB has added enable and disable capability in the rsh and ssh environments. From the Configure KM Defaults: DB2 Instance Settings for DB2_Instance dialog box, you can select the following check boxes so that PATROL for DB2 UDB can monitor an rsh and ssh enabled or disabled environment:
- RSH disabled
- SSH enabled
- LOGIN disabled
The following table shows the usage of the enable and disable capability in the rsh and ssh environments.
