dbca建库报错ORA-03113: end-of-file on communication channel

主要原因是linux的sysctl.conf中的kernel_shmmax配置不合理。

net.ipv4.ip_local_port_range= 9000 65500
fs.file-max = 6815744
kernel.shmall = 10523004
kernel.shmmax = 6465333657
#kernel.shmmax = 65970176
kernel.shmmni = 4096
kernel.sem = 250 32000 100128
net.core.rmem_default=262144
net.core.wmem_default=262144
net.core.rmem_max=4194304
net.core.wmem_max=1048576
fs.aio-max-nr = 1048576

要确认没有重复配置项。
