The following dncsDbData options require special comment: 

 

-U and -L. Cisco Services engineers may occasionally want to unload and load a 
database without using the high-performance features introduced with SR 2.1 
and SR 3.0.  
Important:  Cisco Services recommends that use of the -U and -L options be 
restricted to Cisco Services engineers, only. 

 

-g. Cisco Services engineers designed the -g option to implement the gzip and 
gunzip file compression and uncompression utilities when loading and 
unloading database tables to the hard drive. In some cases, a database unload 
operation that would otherwise not fit into an existing filesystem on the DNCS 
or Application Server, will fit if the -g option is used in conjunction with the -u 
option. Instructions later in this chapter advise system operators to call Cisco 
Services if they discover that an unload of their database will not fit into an 
existing filesystem. 
Important:  Cisco Services recommends that system operators do not use the -g 
option when unloading their database unless instructed to do so by Cisco 
Services.
