Creation and using of Sybase DBCCDB database

Planning:

sp_plan_dbccdb ‘{dbname}’

Creation:

create database dbccdb on … log on …

isql -U sa -i $SYBASE/$SYBASE_ASE/scripts/installdbccdb

DBCCDB Configuration:

sp_configure "number of worker processes", {value_from_sp_plan}

– create named cache for dbccdb
sp_cacheconfig "dbccdb_cache", "{cache_size}M"  

– Size is at least 40 * 16K * (number of working processes)
sp_poolconfig "dbccdb_cache", "{pool_size}M", "16K"

Working space configuration:

sp_dbcc_createws dbccdb, "default", scan_{dbname}, scan, ‘{size_from_sp_plan}’
sp_dbcc_createws dbccdb, "default", text_{dbname}, text, ‘{size_from_sp_plan}’
