DESCRIPTION¶

The cimconfig command manages CIM Server configuration properties. The operations are executed on the local host by submitting requests to the CIM Server. An operation on a current configuration property takes effect immediately, and an operation on a planned configuration property takes effect the next time the CIM Server is started with cimserver (8) . Modifications to a configuration property via cimconfig remain in effect until changed via another cimconfig command. Configuration properties may also be modified temporarily via the cimserver (8) command, in which case, the modification of the configuration property remains in effect for that execution of the cimserver (8) command only. A default value is associated with each configuration property. Each configuration property is initially assigned its default value, until modified by a cimconfig command or cimserver (8) command. Dynamic configuration properties are those whose current values may be set while the CIM server is running.

The following configuration properties are available:

authorizedUserGroups

Description: If set, the value is interpreted as a list of comma-separated user groups whose members may issue CIM requests. A user who is not a member of any of these groups is restricted from issuing CIM requests, with the exception of privileged users (superuser). If unset, any user may issue CIM requests. Note: This configuration property operates in conjunction with other CIM request authorization conditions rather than overriding them.

Default Value: (None)

Dynamic: No

enableAssociationTraversal

Description: If True, the CIM Server will support the four association traversal operators: Associators, AssociatorNames, References, and ReferenceNames.

Default Value: True

Dynamic: No

enableAuditLog

Description: If True, audit log entries for certain types of CIM Server activities will be written to the system log. Examples of audited activities include a CIM Server configuration change, a Provider registration change, an authentication attempt and a modification to the CIM Schema or a CIM Instance. An audit log entry describes the who, what, and when associated with an audited activity.

Default Value: False

Dynamic: Yes

enableIndicationService

Description: If True, the CIM Server will support CIM Indications.

Default Value: True

Dynamic: No

enableHttpConnection

Description: If True, allows connections to the CIM Server using the HTTP protocol

Default Value: False

Dynamic: No

enableHttpsConnection

Description: If True, allows connections to the CIM Server using the HTTPS protocol (HTTP using Secure Socket Layer encryption)

Default Value: True

Dynamic: No

enableNamespaceAuthorization

Description: If True, the CIM Server restricts access to namespaces based on configured user authorizations [user authorizations may be configured using cimauth (8) ]

Default Value: False

Dynamic: No

enableRemotePrivilegedUserAccess

Description: If True, the CIM Server allows access by a privileged user from a remote system. Many management operations require privileged user access. Disabling remote access by privileged user could significantly affect functionality

Default Value: True

Dynamic: No

enableSubscriptionsForNonprivilegedUsers

Description: If True, nonprivileged user of the system will be allowed to manipulate indication subscriptions, indication filters, and listener destination instances otherwise privileged access is required.

Default Value: True

Dynamic: No

forceProviderProcesses

Description: If true, the CIM Server runs Providers in separate processes rather than loading and calling Provider libraries directly within the CIM Server process.

Default Value: True

Dynamic: No

hostname

Description: Can be used to override the local system supplied hostname (without domain) the CIM Server uses to build objects. If not set, querying this configuration option will report the system supplied hostname and behavior is not changed. Setting this value to a valid hostname on CIM Server startup or as planned value will force the server to assume the configured name as the local hosts name. Setting this allows the administrator to set the name that operations such as associator, reference etc. return with object paths. When setting this option, fullyQualifiedHostName should be set also.

In common setups it is not recommended to explicitly set this value. Some scenarios scenarios in which changing the default value makes sense include:

- The case where what the CIM Server shall return to clients for host name is NOT the name of the current host but some administrator defined name (ex. system behind a firewall or some redirector).

- Embedded systems that have a system set hostname which is not valid and needs to be overridden by CIM administrator without changing the actual IP configuration.

Default Value: (blank)

Dynamic: No

fullyQualifiedHostName

Description: Can be used to override the local system supplied fully qualified hostname (with domain) the CIM Server is using to build objects. If not set, querying this configuration option will report the system supplied fully qualified hostname and behavior is not changed. Setting this value to a valid hostname on CIM Server startup or as planned value will force the server to assume the configured name as the local hosts name with domain. Setting this allows the administrator to set the name that indication operations and the CIM_ObjectManager assume for SystemName returned as instance and key properties.

In common setups it is not recommended to explicitly set this value. Some scenarios scenarios in which changing the default value makes sense include:

- The case where what the CIM Server shall return to clients for host name is NOT the name of the current host but some administrator defined name (ex. system behind a firewall or some redirector).

- Embedded systems that have a system set hostname which is not valid and needs to be overridden by CIM administrator without changing the actual IP configuration.

Default Value: (blank)

Dynamic: No

idleConnectionTimeout

Description: If set to a positive integer, this value specifies a minimum timeout value for idle client connections. If set to zero, idle client connections do not time out.

A client connection is considered idle when it is not in the process of sending a request and the CIM Server is not processing a request from that connection. An idle connection timeout allows reclamation of the system resources allocated for idle CIM Server connections. Note that the CIM Server may allow an idle connection to persist longer than the configured timeout value based on server activity.

Some client applications may not behave correctly if a connection timeout is introduced. Client compatibility should be considered when configuring an idle connection timeout value. The idle connection time is computed using the system clock. Thus, resetting the system clock may cause unexpected timeout behavior.

Default Value: 0

Dynamic: No

listenAddress

Description: Network interfaces, if specified, cimserver(8) should listen to for connection requests. It accepts a comma seperated list(without space) of network interfaces. Both ipv4 and ipv6 addresses is accepted. Default value of "All" make cimserver to listen to all the available network interfaces. Examples include:

-listenAddress=All

-listenAddress=121.12.33.112

-listenAddress=121.33.21.26,127.0.0.1,fe80::fe62:9346%eth0

Default Value: All

Dynamic: No

maxFailedProviderModuleRestarts

Description: If set to a positive integer, this value specifies the number of times a failed provider module with indications enabled are restarted automatically before being moved to Degraded state. If set to zero, failed provider module is not restarted with indications enabled automatically and will be moved to Degraded state immediately.

This option controls the automatic re-enabling of the failed provider module with indications enabled. If the provider module with indications enabled fails very frequently, it affects the CIMServer normal operations because CIMServer would be busy reloading the provider module every time it fails. This option would be helpful if a long running indication provider crashes and the management application wants to receive the indications from the provider while provider fix is being delivered.

In case of provider module grouping, if one of the indication provider crashes, it affects all indication providers in the provider modules of the group.

Note that this is the facility provided by the CIMServer for temporary recovery of the provider and the ultimate goal SHALL be to fix the faulty provider.

Default Value: 3

Dynamic: Yes

maxIndicationDeliveryRetryAttempts

Description:If set to a positive integer, value defines the number of times indication service will enable the reliableIndication feature and try to deliver an indication to a particular listener destination.This does not effect the original delivery attempt. A value of 0 disables reliable indication feature completely, and cimserver will deliver the indication once.

This value is used to set the CIM_IndicationService.DeliveryRetryAttempts property. See CIM_IndicationService.DeliveryRetryAttempts property for more details.

Default Value: 3

Dynamic: No

minIndicationDeliveryRetryInterval

Description:If set to a positive integer, this value defines the minimal time interval in seconds for the indication service to wait before retrying to deliver an indication to a listener destination that previously failed. Cimserver may take longer due to QoS or other processing.

This value is used to initialize the property CIM_IndicationService.DeliveryRetryInterval. See CIM_IndicationService.DeliveryRetryInterval property for more details.

Default Value: 30

Dynamic: No

shutdownTimeout

Description: When a cimserver -s shutdown command is issued, specifies the maximum time in seconds for the CIM Server to complete outstanding CIM operation requests before shutting down; if the specified timeout period expires, the CIM Server will shut down, even if there are still CIM operations in progress. Minimum value is 2 seconds.

Default Value: 30

Dynamic: Yes

slpProviderStartupTimeout

Description: Timeout value in milli seconds used to specify how long the registration with an SLP SA may take. Registration will be retried three times.

This value only needs to be increased in case that the loading of a set of providers whose implementation of a registered profile takes very long.

Default Value: 300000

Dynamic: No

socketWriteTimeout

Description: Specifies the number of seconds the CIM Server will wait for a client connection to be ready to receive data. If the CIM Server is unable to write to a connection in this time, the connection is closed.

A client connection can become unable to receive data if the client fails to read the data that has already been sent. This timeout allows the CIM Server to reclaim resources that are allocated to a malfunctioning client.

One might consider increasing this timeout value if the CIM Server prematurely closes connections with well-behaved clients.

Default Value: 20

Dynamic: Yes

sslClientVerificationMode

Description: Defines the desired level of support for certificate-based authentication. It can be set to required, optional or disabled. If set to required, the CIM Server will require all clients connecting over HTTPS to authenticate using a certificate. If the client certificate is not sent or not trusted the connection will be rejected. If set to optional, the CIM Server will allow, but not require, HTTPS clients to authenticate using a certificate. If the client does not send a certificate, the CIM Server will attempt to authenticate the client using HTTP basic authentication. If set to disabled, the CIM Server will not allow HTTPS clients to authenticate using a certificate. Basic authentication will be used to authenticate all HTTPS clients. This property is only used if enableHttpsConnection is true.

Default Value: disabled

Dynamic: No

traceFileSizeKBytes

Description:Defines the size of the tracefile in Kilo bytes. The trace file will be rolled once its size exceeds the specified size."

Default Value: 1048576

Dynamic: Yes

numberOfTraceFiles

Description:Specifies the number of the tracefiles for rolling.

Default Value: 3

Dynamic: Yes

sslCipherSuite

Description: String containing OpenSSL cipher specifications to configure the cipher suite the client is permitted to negotiate with the server during the SSL handshake phase. The value should be mentioned between single quotes since it can contain special characters like .+, !, -.

Default Value: DEFAULT (The default cipher list of OpenSSL)

Dynamic: No

sslBackwardCompatibility

Description:This setting specifies whether the ssl supports SSLv3. Ideally for security Compilance purposes it is by default set to false.

Default Value: false

Dynamic: No

webRoot

Description:Points to a location where the static web pages to be served by the pegasus webserver are stored.

Default Value: /var/tog-pegasus/www

Dynamic: No

indexFile

Description:Specifies the name of index file used by pegasus webserver, default to index.html, This file should be available at the webRoot path.

Default Value: index.html

Dynamic: No

mimeTypesFile

Description: Refers to the file which holds the mime types being served by the pegasus webserver.

Default Value: /var/tog-pegasus/www/mimeTypes.txt

Dynamic: No

httpSessionTimeout

Description: If set to a positive integer, this value specifies a HTTP session lifetime in seconds. After initial authentication using standard HTTP mechanisms (HTTP Basic or Negotiate authentication), the server generates a cookie and sends it back to the client, as described in RFC 6265. The client can then use the cookie in subsequent requests to skip the usual HTTP authentication. The cookie is valid only for period of time specified by this configuration option. If set to zero, session management is turned off and CIM server will not issue cookies. This option is available only when Pegasus was compiled with PEGASUS_ENABLE_SESSION_COOKIES set to 'true'.

Default Value: 0

Dynamic: Yes

If both the enableHttpsConnection and enableHttpConnection properties are set to False , neither HTTP nor HTTPS connections will be allowed. On some platforms, the OpenPegasus CIM Server has been enhanced to include support for a local (single system), non-standard protocol. This allows the OpenPegasus CIM Server to continue to receive and process requests from local OpenPegasus CIM Clients even if both HTTP ports are disabled. If a local protocol is not supported, the CIM Server will be shut down and disabled from automatically being re-started.

The current and planned values of the configuration properties are stored in the files /var/opt/tog-pegasus/cimserver_current.conf and /var/opt/tog-pegasus/cimserver_planned.conf , respectively. The configuration properties may only be modified via the cimconfig and cimserver (8) commands; the files must not be edited directly.
