The onconfig.std file contains # two initial entries: a default entry from which # to base new page size entries on, and an entry # for the operating system default page size. # When you add a dbspace with a different page size, # IDS adds a BUFFERPOOL entry to the onconfig file # with values that are the same as the default # BUFFERPOOL entry, except that the default # keyword is replaced by size=Nk, where N is the # new page size. With interval checkpoints, these # values can now be set higher than in previous # versions of IDS in an OLTP environment. # AUTO_LRU_TUNING - Enables (1) or disables (0) automatic tuning of # LRU queues. When this parameter is enabled, IDS # increases the LRU flushing if it cannot find low # priority buffers for number page faults. ################################################################### BUFFERPOOL default,buffers=10000,lrus=8,lru_min_dirty=50.00,lru_max_dirty=60.50 BUFFERPOOL size=2k,buffers=50000,lrus=8,lru_min_dirty=50,lru_max_dirty=60 AUTO_LRU_TUNING 1
3）建立chunk目录并赋予权限
mkdir chunk cd chunk touch rootdbs logdbs tempdbs phydbs datadbs chmod 660 *.dbs ls -lh
4）配置数据库空间信息
onspaces -c -d rootdbs -t -p /opt/info1/chunk/rootdbs -o 40 -s 10240; onspaces -a logdbs -p /opt/info1/chunk/logdbs -o 40 -s 10240; onspaces -c -d datadbs -p /opt/info1/chunk/datadbs -o 40 -s 20480; onspaces -c -d tempdbs -p /opt/info1/chunk/tempdbs -o 40 -s 10240;
5）检查数据库信息
onstat -l
onstat
