# [How to Quickly Ignore ORA Error on Agent Layer](https://www.pythian.com/blog/how-to-quickly-ignore-ora-error-on-agent-layer)

I had a very specific situation where I wanted to ignore an error from a specific agent. It turns out that it is easier and quicker to ignore a specific error using an OEM Metric. How? By using an agent parameter. *adrAlertLogErrorCodeExcludeRegex.*

## How to do it?

 In *[AGENT_INST]/sysman/config/emd.properties,* add a line with these parameters and the Regex to ignore the desired error or message. Ignoring all ORA-700, for example, can be done by:

```
adrAlertLogErrorCodeExcludeRegex=.*700.*
```

 Now to ignore specific errors, for example, *ORA 700 [kskvmstatact: excessive swapping observed]:*

```
adrAlertLogErrorCodeExcludeRegex=.*kskvmstatact.*
```

After this parameter inclusion, a restart on the agent is required. This is also well-documented as per MOS [**EM 12c, 13c: How to Disable or Suppress OEM Alerts for Alert Log Error ORA-700 (Doc ID 2406779.1)**](https://support.oracle.com/epmos/faces/DocumentDisplay?id=2406779.1) Hope this helps!
