Abstract: The disclosed techniques reduce a responsiveness time for a secondary node state of a database in switching from a second computing node to replace a first computing node acting in a primary node state, with both computing nodes performing the same database queries. The second node receives information regarding queries performed by the first node while in the primary state. In some embodiments, the second node retrieves, from a transaction log, log records detailing operations performed for database transactions. In some embodiments, the second node inserts, based on the log records, data records of the transactions into an in-memory cache of the second node that stores chains of database records from different transactions. Upon receiving sufficient information to switch to the primary state, the second node changes a mode of operation during failover making a committed transaction available for reads by subsequent database queries prior to record reordering.

Abstract: The present invention provides a method for the preparation of an insensitive high enthalpy explosive Dihydroxylammonium 5,5?-bistetrazole-1,1?-diolate (TKX-50) in the presence of N,N-dimethylformamide, N,N-dimethylacetamide, or N-Methyl-2-pyrrolidone as a solvent via a four-step, one-pot reaction route to obtain a final product after four reaction steps. The more dangerous intermediate diazidoglyoxime may be solved by the one-pot method without the need of isolation. Further, the cyclization reaction is carried out in the presence of dropwisely added concentrated sulfuric acid to replace hydrochloric gas so no hydrochloric gas generator is needed to greatly reduce the amount of waste acid so as to effectively reduce the cost by avoiding using hydrochloric gas steel cylinders which require much safety equipment.
