Hi, We have NNM7.51 and database oracle 10g. Now all the routers that are added in NNM are updated in the database table named NNM_EVENT_DETAIL. Now the problem is suppose one router didnot throw any alert for 10-15 days then that particular routes name get removed from the databases table. As a result new alerts doesnot get updated in the database. Kindly suggest me whether this deletion is totally due to some procedures running in orcale or NNM is triggering any procedure in the database. Please help.
