Description:
After installing Windows updates and restarting the iProcess Engine, you may receive warning messages when using command line utilities in iPE stating that the state oci.dll and SQLlib80.dll files are not found.

Symptoms:
When running commands such as swutil, swadm, swsvrmgr and sweaireg, you may see entries like the following added to the normal command output.

LoadLibraryFromPath: FQ Dll C:\Windows\system32\oci.dll is not found, error: 0x7e
LoadLibraryFromPath: FQ Dll C:\Windows\system32\SQLLib80.dll is not found, error: 0x7e

Cause:
Microsoft Security Update 3126587 (https://support.microsoft.com/en-us/kb/3126587) triggers these added warnings about missing .dll files. The iPE command line binaries do not call these .dll files directly, so the entries can be ignored. The added warnings are displayed by iPE binaries that issue COM+ events that utilize MSDTC. 

1). The messages can be ignored as they do not cause any functionality problems.

2). When using the Windows (Oracle) version of iPE, navigate to the following registry key using regedit.

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\MSDTC\MTxOCI

Modify the OracleSqlLib and the OracleXaLib keys to be valid .dll files for your Oracle client.  As of this writing, all supported iPEs are using 11g Oracle clients, so the value for OracleSqlLib would be orasql11.dll and the value for OracleXaLib would be oraclient11.dll. After making these modifications, the warning messages should no longer be displayed.

When running command line utilities for TIBCO iProcess Engine (iPE) on Windows, you may encounter "oci.dll is not found" and "SQLlib80.dll is not found" warning messages.
