Adjusting OMi Settings

To increase robustness of your OEM topology integration with OMi, you must adjust the setting for a particular configuration type attribute in OMi. Additionally, to avoid problems caused by a complex monitored infrastructure, you may want to adjust an OMi setting for data chunking.

RTSM Setting: Data Push Chunk Size

If the infrastructure monitored by OEM is relatively large, the quantity of the forwarded topology data is also large—at least the content sent in response to the initial collection query. In such circumstances, to avoid disruptions in topology forwarding, increase the data push chunk size in OMi. Follow the steps:

1. Log on to the OMi web interface.

2. Navigate to Administration > Setup and Maintenance > Infrastructure Settings.

3. Click the Foundations radio button.

4. From the Foundations drop-down list, select RTSM Fuses.

5. In the RTSM Fuses - Fuses Settings part, click Edit icon on the right-hand side of the Data Push Chunk Size.

6. In the Edit Setting window, in the Value text box, replace the default value (2000) with a suitably higher value. For example, you can specify the value 20000.

When the entire OEM topology is available in OMi, you can revert the Data Push Chunk Size option to its predefined value to avoid potential decrease in OMi performance.

Configuration Type Attribute: External ID

Fully qualified domain names (FQDNs) of the monitored systems might be relatively long. To accommodate longer FQDNs, adjust the size of the External ID attribute of the data configuration item (CI) type in OMi. Follow the steps:

recommends that you perform the procedure for adjustment of the External ID attribute in any case.

1. Log on to the OMi web interface.

2. Navigate to Administration > Setup and Maintenance > Infrastructure Settings.

3. Click the Foundations radio button.

4. From the Foundations drop-down list, select RTSM.

5. In the RTSM - General Settings part, click Edit on the right-hand side of the line for the Object Root setting.

6. In the Edit Setting pane, replace the content of the Value text box with the string root.

7. Click Save to apply the change and close the window.

8. Navigate to Administration > RTSM Administration > Modeling > CI Type Manager.

9. In the CI Types pane, select Data under Root.

10. In the toolbar, click Attributes.

11. In the Display Name column, select External ID.

12. Click Edit in the toolbar.

13. In the Details page of the Edit Attribute window, replace the default value in the Value Size text box (50) with a suitably higher value. For example, you can specify the value 300.

14. Click OK to apply the change and close the window.
