Hi All,
I changed the log file size in the DB without calculating the real server space. Now the DB will not startup.

Log File Size is given below,

[xxxxx@xxxxxxx ~]$ db2 get db cfg for rcb |grep 'LOG'
Catalog cache size (4KB) (CATALOGCACHE_S Z) = 300
Log buffer size (4KB) (LOGBUFSZ) = 2159
Log file size (4KB) (LOGFILSIZ) = 100000...
