Fault Telemetry Options

You can configure the fault notification destinations using various methods.

Adding SNMP trap destinations using Oracle Exadata Deployment Assistant (OEDA) is the recommended method for new installations. After the initial configuration with OEDA, you can modify or add new fault notification destinations using the command line utilities, such as DBMCLI, CellCLI, dcli, or exadcli.

To configure fault notification destinations, modify the SNMP subscriber attribute on the database or storage servers. The information you provide defines the SNMP trap destination.

Note:

Oracle ASR can only use the management network. Ensure that the management network is configured to enable Oracle ASR to run on either eth0 on the interfaces, or net0 on the rear of the server.

SNMP Subscriber Options

When configuring the SNMP subscriber, you set some or all of the following options:

• host=[ASR Manager host name or IP] is the Oracle ASR Manager host name or IP address. The Oracle ASR Manager host name can be used when DNS is enabled for the site. If DNS is not running, then the IP address is preferred. However, you can use the Oracle ASR Manager host name if the entry is added to the /etc/hosts file.
• type=asr represents the Oracle ASR Manager being a special type of SNMP subscriber.
• community=public is the required value of the community string. This value varies for each implementation because you can modify it to be a different string based on your network requirements.
• port=162 is the SNMP port. This port value is customer-dependent. You can configure it as a different port based on your network requirements. Or, you may need to change the port value in order for Oracle ASR to work correctly in a managed environment.
• asrmPort is an optional element that supports automatic diagnostic package uploads for Service Requests (SR). The default value is 16161. If you plan to use HTTP for upload, then the value should match the HTTP port configured on Oracle ASR Manager. If you plan to use HTTPs for upload, then the value should match the HTTPs port configured on Oracle ASR Manager. The value should be set to the same value as displayed for "HTTP Port" or "HTTPS/SSL Port" in the output of the command asr show_http_receiver on the Oracle ASR Manager host.

• fromIP enables you to specify an IP address from which the trap is sent. If this field is not specified, then it defaults to the IP address associated with eth0. To support automatic diagnostic package uploads, you must set fromIP on the database nodes to the value of the IP address of the eth0 network interface. Otherwise, use this field if the default IP address is not registered with Oracle ASR Manager. Oracle ASR Manager only processes SNMP traps that are sent from IP addresses that Oracle ASR Manager recognizes.

  The fromIP field is allowed only for snmpSubscribers whose type is either ASR or v3ASR.
