Presentation

Script $gvsqw_SybBin/sqwsyb_DumpDatabase.ksh :


Generate Dump database
You can choose type of Dump (by default full):

  • full -> full Dump
  • inc -> Dump tran
  • stb -> Dump tran for standby
  • fstb -> full Dump plus Dump tran for standby


Script automatically determine how many stripes
Makes backup of master..syslogins (permet to make synchronisation on Load)
Makes purges of Dump generations
You can change default values:

  • compression level
  • force number of stripes
  • size max of a stripe
  • number of Dump generations to keep online



Online help

The online help is available for most scripts with the -h option.
Ex: $gvsqw_SybBin/sqwsyb_DumpDatabase.ksh -h
