14 Automatic Diagnostic Collections

Oracle Trace File Analyzer monitors your logs for significant problems, such as internal errors like ORA-00600, or node evictions.

14.1 Collecting Diagnostics Automatically

This section explains automatic diagnostic collection concepts.

If Oracle Trace File Analyzer detects any problems, then it carries out the following actions:

  • Runs necessary diagnostics and collects all relevant log data at the time of a problem

  • Trims log files around the time of the problem so that Oracle Trace File Analyzer collects only what is necessary for diagnosis

  • Collects and packages all trimmed diagnostics from all nodes in the cluster, consolidating everything on a single node

  • Stores diagnostic collections in the Oracle Trace File Analyzer repository

  • Sends you email notification of the problem and details of diagnostic collection that is ready for upload to Oracle Support

Figure 14-1 Automatic Diagnostic Collections

Description of Figure 14-1 follows
Description of "Figure 14-1 Automatic Diagnostic Collections"

Oracle Trace File Analyzer uses a flood control mechanism. Repeated errors do not flood the system with automatic collections.

Identifying an event triggers the start point for a collection and five minutes later Oracle Trace File Analyzer starts collecting diagnostic data. Starting five minutes later is to capture any other relevant events together. If events are still occurring after five minutes, then diagnostic collection continues to wait. Oracle Trace File Analyzer waits for 30 seconds with no events occurring, up to a further five minutes.

If events are still occurring after 10 minutes, then a diagnostic collection happens. A new collection point starts.

After the collection is complete, Oracle Trace File Analyzer sends email notification that includes the location of the collection, to the relevant recipients.

If your environment can make a connection to oracle.com, you can then use Oracle Trace File Analyzer to upload the collection to a Service Request. 

$ tfactl set autodiagcollect=ON|OFF

Automatic collections are ON by default.

14.2 Configuring Email Notification Details

Configure Oracle Trace File Analyzer to send an email to the registered email address after an automatic collection completes.

To send emails, configure the system on which Oracle Trace Analyzer is running. You must configure notification with a user email address to enable it to work.

To configure email notification details:

  1. To set the notification email to use for a specific ORACLE_HOME, include the operating system owner in the command:
    tfactl set notificationAddress=os_user:email
    For example:
    tfactl set notificationAddress=oracle:some.body@example.com
  2. To set the notification email to use for any ORACLE_HOME:
    tfactl set notificationAddress=email
    For example:
    tfactl set notificationAddress=another.body@example.com
  3. Configure the SMTP server using tfactl set smtp.

    Set the SMTP parameters when prompted.

    Table 14-2 tfactl diagnosetfa Command Parameters

    Parameter Description

    smtp.host

    Specify the SMTP server host name.

    smtp.port

    Specify the SMTP server port.

    smtp.user

    smtp.bcc

    Specify the comma-delimited list of BCC mail IDs.

    smtp.debug

    Set the Debug flag to true or false.

    Note:

    You can view current SMTP configuration details using tfactl print smtp.

  4. Verify SMTP configuration by sending a test email using tfactl sendmail email_address.

    When Oracle Trace File Analyzer detects a significant error has occurred it will send an email notification as follows:

    Figure 14-2 Email Notification

    Description of Figure 14-2 follows
    Description of "Figure 14-2 Email Notification"
  5. Do the following after receiving the notification email:
    1. To find the root cause, inspect the referenced collection details.
    2. If you can fix the issue, then resolve the underlying cause of the problem.
    3. If you do not know the root cause of the problem, then log an SR with Oracle Support, and upload the collection details.

Example 14-1 tfactl set smtp

# /u01/app/11.2.0.4/grid/bin/tfactl set smtp 

.---------------------------.
| SMTP Server Configuration |
+---------------+-----------+
| Parameter | Value |
+---------------+-----------+
| smtp.auth | false |
| smtp.from | tfa |
| smtp.user | - |
| smtp.cc | - |
| smtp.port | 25 |
| smtp.bcc | - |
| smtp.password | ******* |
| smtp.host | localhost |
| smtp.to | - |
| smtp.debug | true |
| smtp.ssl | true |
'---------------+-----------'

Enter the SMTP property you want to update : smtp.host

Enter value for smtp.host : myhost.domain.com

SMTP Property smtp.host updated with myhost.domain.com
