Viewing the Correlation Property Page
To view the event correlation property page 1 In the Explorer pane, expand Elements.
2 Right‐click the CiscoWorks2000 DFM adapter element, then click Properties to open the Status property page.
3 In the left pane, click Correlation to open the Correlation property page:
Correlating Immediately
To activate real‐time correlation for an adapter element:
1 In the Explorer pane, right‐click the CiscoWorks2000 DFM adapter element, then click Correlate Now.
The Domain Manager starts the event correlation process, which continues to run in the background until it finishes.
2.8.14 Recomputing the DFM Codebook
The Codebook is a casualty mapping between problems and symptoms that is computed by the CiscoWorks2000 DFM Domain Manager’s correlation engine. Use Operations Center operations to request a consistency update from the Domain Manager to regenerate the correlation codebook.
To recompute the codebook:
1 In the Explorer pane, right‐click the CiscoWorks2000 DFM adapter element, then click Recompute Codebook.
The Domain Manager performs the regeneration of the correlation cookbook as a background process.
2.9 Computer Associates (CA) Spectrum
This adapter was previously named Aprisma SPECTRUM, and has the same functionality as the former one.
Create an adapter for each instance of Spectrum on the network (see Section 5.1, “Creating an Adapter,” on page 193). Also modify the adapter properties (see Section A.10, “Computer Associates Spectrum,” on page 304).
The Spectrum integration automatically instantiates a copy of the Visigenic ORB for the sole purpose of communicating with the SpectroServers. It is necessary to obtain a series of Spectrum CORBA API JAR files directly from Computer Associates and copy them to the Operations Center installation directory.
IMPORTANT: When creating an adapter, select the CA Spectrum adapter. Only select the older Aprisma SPECTRUM driver if upgrading from a previous release.
Refer to the following topics to integrate to Spectrum:
Section 2.9.1, “Integrating Spectrum,” on page 57
Section 2.9.2, “Integrating Spectrum Event Descriptions,” on page 60
Section 2.9.3, “Enabling the CORBA Naming Service,” on page 60
Section 2.9.4, “Understanding Spectrum Adapter Features,” on page 61
2.9.1 Integrating Spectrum
To integrate spectrum:
1 Obtain the following files from Computer Associates, then copy them to the directories listed:
For Version Obtain These Files Copy To
2 If upgrading an existing installation, do the following:
Copy the contents from SpectrumInstallation/tomcat/webapps/spectrum/WEB-INF to the Operations Center server. Specify this location in the Spectrum OneClick Topology Config Directory adapter property when you create an adapter.
Copy the Spectrum Cause files from SpectrumInstallation/SG-Support/CsPCause to the Operations Center server. Specify this location in the Spectrum Cause File Directory property when you create an adapter.
For more information about adapter properties, see Section A.10, “Computer Associates Spectrum,” on page 304.
4 Set up the Spectrum SpectroServer to allow connections from the Operations Center server.
Use the Spectrum Control Panel or edit the .hostrc file in the Spectrum installation directory.
Since Spectrum security requires this change, perform this step for each SpectroServer connected to Operations Center.
In the .hostrc file, add a line that contains the IP address of the Operations Center server. Do not stop the SpectroServer; changes update approximately within a minute.
The Spectrum User property value (see Section A.10, “Computer Associates Spectrum,” on page 304) for the Spectrum adapter must match the IP address entered in the .hostrc file.
5 Enable the Corba Naming service on each Spectrum server to allow ORB independence and communication with the Operations Center server.
For more information, see the Spectrum documentation.
6 Restart the Operations Center server.
For instructions, see “Manually Starting the Operations Center Server” and “Starting the Operations Center Server in UNIX” in the Operations Center 5.0 Server Installation Guide.
7 Create an adapter for each instance of Spectrum on the network.
Because Spectrum requires separate sets of CORBA API libraries for Spectrum versions 8.x, and 9.0; separate adapter types exist to support both Spectrum versions 8.x, and 9.0. You must create a separate adapter for each version of the Spectrum server.
Adapters can be created for each Spectrum server, or an adapter can connect to a SpectroServer designated as a master catalog. When doing the latter, other SpectroServers must be added to the topology of the master catalog for them to show up in the adapter. For more information on adding SpectroServers to the master catalog using the Spectrum OneClick Console, consult the Spectrum documentation.
A separate Spectrum adapter license is required for each SpectroServer that Operations Center connects to, even though a single adapter can connect to multiple SpectroServers.
8 Modify adapter properties. For a detailed list, see Section A.10, “Computer Associates Spectrum,” on page 304.
2.9.2 Integrating Spectrum Event Descriptions
To integrate event descriptions from Spectrum:
1 Copy the contents of the Spectrum SG-Support directory to a directory named SG-Support on the Operations Center server.
2 Set the adapter property Spectrum installation Directory (see Section A.10, “Computer Associates Spectrum,” on page 304) to the parent directory of the SG-Support directory.
For example, if the directory is /opt/formula/SG-Support, then set the property to /opt/
formula.
After upgrading Operations Center, it is necessary to re‐create all existing Spectrum adapter instances, to allow the Spectrum adapter to dynamically load the libraries for all existing adapters.
Subsequent sections provide more details.
2.9.3 Enabling the CORBA Naming Service
When integrating Spectrum, note that the CORBA naming service is disabled by default. To enable the service, modify the <$SPECROOT>/lib/SDPM/partslist/NAMINGSERVICE.idb file so that the process automatically starts the Visibroker naming service.
