I refuse to purchase support for CSS in WordPress, so I found a workaround. The guys at Pelago have a really quick and easy way to make CSS tags inline, thus making your tweaks visible in WordPress. It’s intended for use with e-mail, but a it’s a cool WP hack for those of us who refuse to pony up.

- Software Targets Without Inventory
- OCM is not installed or configured – executeCommand(): failed to verify harvester jar
- No Oracle Homes found under Net Services Administration
After deploying several Oracle Enterprise Manager Agents on various hosts, Grid Control was returning several error messages. These errors include software targets without inventory messages, GC Harvester and OCM issues, and Net Services Administration errors. In my case the errors were confined to one host, but only a portion of the databases on that host were returning errors. Several websites suggested stopping, un-securing and securing the management agent. Other sites suggested installing Oracle Configuration Manager (OCM). These actions did not rectify the problems. I eventually determined that a lowercase drive letter was the culprit and was able to quickly fix the issue by removing the databases in Grid Control, manually re-adding each database, and changing the Oracle home path from c:\oracle to C:\oracle.
|OS||Microsoft Windows Server 2003 SP2 (32-bit)|
|Database||Oracle 10g 10.2.0.4.0|
|Oracle 11g 188.8.131.52.0|
|Grid Control||Oracle Enterprise Manager 11g Release 1 Grid Control 184.108.40.206.0|
In the lower right of the home page, selecting Database Installations from the Deployments Summary drop-down returns the following error.

|Software Targets Without Inventory: 3 of 12|
|Database Installations||Targets||Installations||Patches Applied|

|Oracle Database 11g 220.127.116.11.0||1||2||No|
Clicking the link on the front page or selecting the “Deployments” tab, clicking “Host Configuration Collection Problems” and selecting the “Software Targets Without Inventory” sub-tab displays the following table.
Host Configuration Collection Problems
|Target Name||Target Type||Host||Oracle Home|
This problem is further detailed by following the “System Errors” link at the bottom of the page.
Management Services and Repository
Navigating to the host page and clicking the “Net Services Administration” link returns the following error.
Net Services Administration
|Select||Configuration File Location||Oracle Home|
|No Oracle Homes found|
Selecting the targets page for a particular host lists the agents, listeners, and databases on that host. The difference between the databases is the drive letter of the installed location. Note that MyDatabase3 has a lowercase “c” while the other databases have an uppercase “C”.
From the databases tab, click the radio button next to the problematic database and click the “Remove” button. Once removed, click the “Add” button, select the Host and click the “Continue” button. Select the checkbox next to the database and click the configure icon.
Targets Discovered on Host: ServerName
When adding a target, you must change the lowercase drive letter to an upper case drive letter.
