Follow the naming conventions when you name an agent instance or a database connection.
For directions regarding how to set the agent instance name and database connection name, see Local configuration for local instances, and Remote installation and configuration for remote agent instances.
Follow the naming conventions when you name an agent instance.
For RZ nodes, the following part of the node name must not be longer than 32 characters:
Instance:Hostname:rz
Where:
Oracle Database Extended - Instance:Hostname:rz
If the Instance:Hostname:RZ part is longer than 32 characters, Instance:Hostname is truncated. After the truncation, if there are agent instances with the same node or subnode name, and these agent instances are connected to the same hub Tivoli Enterprise Monitoring Server, the agent instances do not work correctly.
Follow the naming conventions when you name a database connection.
For RDB subnodes, ASM subnodes, and DG subnodes, the subnode ID part of a subnode name must not be longer than 24 characters:
DBConnection-Instance-Hostname
Where: DBConnection is an alias that you set for the database connection.
If the subnode ID is longer than 24 characters, it is truncated. After the truncation, if there are database connections with the same subnode name under the same hub Tivoli Enterprise Monitoring Server, the monitoring for these database connections does not work correctly. Also, for a subnode with a truncated subnode ID, the Agent_Event, RDB_Alert_Log_Details, or ASM_Alert_Log_Details situation is not issued if the conditions for any of these situations are met. To avoid the subnode being truncated, reduce the length of the database connection name, agent instance name, or hostname; or, see Changing default naming conventions for database connections for information.
To avoid a subnode name that is truncated, change the subnode naming convention by using environment variables.
To avoid a subnode name that is truncated, change the subnode naming convention by setting the following environment variables: KRZ_SUBNODE_INCLUDING_AGENTNAME, KRZ_SUBNODE_INCLUDING_HOSTNAME, and KRZ_MAX_SUBNODE_ID_LENGTH.
