Checkpointing a database is a vital technique to reduce the recovery time in the presence of a failure. For distributed databases, checkpointing also provides an efficient way to perform global reconstruction. In this paper, we survey and classify previous approaches for checkpointing a distributed database. Since the need for global reconstruction is infrequent in most distributed databases, a less restrictive and less resource-consuming approach to checkpoint distributed databases in an integrated distributed database system is recommended over a transaction consistent checkpoint approach. For a federal or multidatabase systems, any type of global consistent checkpoint is difficult to achieve without violating local autonomy. |

According with the studies realized the litter from peach palm (pupunha) contibutes with only 110 g/ha or 0,1% of total soil C to the C budget of the system. On the other hand it produces high quantities of root exudates. About 16.500 kg/ha C or 15% of total soil C respectively are released into the soil. Taking into account the C loss by microbial respiration and root respiration peach palm contributes with 10.700 kg/ha or 10% of total soil C respectively to the C budget of the system. Compared to C from root exudates the quantity of C from microbial biobass under peach palm is low. Only 45 kg/ha or 0,0004% of the total C originate from the microbial biomass. |
