Special note to unregistered users

This forum is intended only as a means to contact us if you are having trouble with your account. This forum is the only area on the site where even unregistered users can post. But because some spammers were using this to post spam, we have changed things a little bit. When an unregistered user posts, that post will go into a "Moderation Queue". A Moderator must approve the post before it actually become visible. So don't despair if you post something and it does not immediately show up. Your post have not been lost and will we get to it when we can. But, needless to say, any spam in the Moderation Queue will be deleted forthwith.

Hi everyone, I am working a contract and the customer has not registered there RHEL 5 servers. They have a cluster of servers and it would seem that they all stop logging in messages @ appox 15:50 and then start logging again at 4:04 am. Is this a normal thing for non-registered? Lee (3 Replies)

wsreg_unregister(3WSREG)			    Product Install Registry Library Functions				  wsreg_unregister(3WSREG)

wsreg_unregister - remove a component from the product install registry SYNOPSIS
cc [flag ...] file ...-lwsreg [library ...] #include <wsreg.h> int wsreg_unregister(const Wsreg_component *comp); DESCRIPTION
The wsreg_unregister() function removes the component specified by comp from the product install registry. The component will only be removed if the comp argument has a matching uuid, instance, and version. Usually, the component retrieved through a call to wsreg_get(3WSREG) before being passed to the wsreg_unregister() function. If the component has required components, the respective dependent components will be updated to reflect the change. A component that has dependent components cannot be unregistered until the dependent components are uninstalled and unregistered. RETURN VALUES
Upon successful completion, a non-zero return value is returned. If the component could not be unregistered, 0 is returned. EXAMPLES
Example 1: Unregister a component. The following example demonstrates how to unregister a component. #include <stdio.h> #include <wsreg.h> int main(int argc, char **argv) { char *uuid = "d6cf2869-1dd1-11b2-9fcb-080020b69971"; char *location = "/usr/local/example1_component"; Wsreg_query *query = NULL; Wsreg_component *comp = NULL; /* Initialize the registry */ wsreg_initialize(WSREG_INIT_NORMAL, NULL); /* Query for the component */ query = wsreg_query_create(); wsreg_query_set_id(query, uuid); wsreg_query_set_location(query, location); comp = wsreg_get(query); if (comp != NULL) { /* The query succeeded. The component has been found. */ Wsreg_component **dependent_comps; dependent_comps = wsreg_get_dependent_components(comp); if (dependent_comps != NULL) { /* * The component has dependent components. The * component cannot be unregistered. */ wsreg_free_component_array(dependent_comps); printf("The component cannot be uninstalled because " "it has dependent components "); } else { /* * The component does not have dependent components. * It can be unregistered. */ if (wsreg_unregister(comp) != 0) { printf("wsreg_unregister succeeded "); } else { printf("unregister failed "); } } /* Be sure to free the component */ wsreg_free_component(comp); } else { /* The component is not currently registered. */ printf("The component was not found in the registry "); } wsreg_query_free(query); } USAGE
Components should be unregistered before uninstallation. If the component cannot be unregistered, uninstallation should not be performed. A component cannot be unregistered if other registered components require it. A call to wsreg_get_dependent_components() can be used to determine if this situation exists. See wsreg_add_dependent_component(3WSREG). A successful unregistration of a component will result in all components required by the unregistered component being updated in the prod- uct install registry to remove the dependency. Also, child components will be updated so the unregistered component is no longer regis- tered as their parent. When unregistering a product, the product should first be unregistered, followed by the unregistration of its first feature and then the unregistration and uninstallation of the components that comprise that feature. Be sure to use this top-down approach to avoid removing a component that belongs to a product or feature that is required by a separate product. ATTRIBUTES
