Investigating Logs for Errors

Use Oracle Trace File Analyzer to analyze all of your logs across your cluster to identify recent errors.

To find all errors in the last one day:
```
$ tfactl analyze -last 1d
```
To find all errors over a specified duration:
```
$ tfactl analyze -last 18h
```
To find all occurrences of a specific error on any node, for example, to report ORA-00600 errors:
```
$ tfactl analyze -search "ora-00600" -last 8h
```
