环境如下:
SUSE11sp2 64bit (内核3.0.13),12C64G内存
oracle11.2.0.3.5,单节点环境,sga分配25g,pga分配25g
在进行impdp dc/dc schemas=DC NETWORK_LINK=dwdb68 logfile=impdp.log parallel=8 directory=dpdir时,遇到如下错误
Connected to: Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production

在dwdb68的数据库中,DC这个schemas对象和表较多。
查了google和metalink,设置了下述内存参数(vm.max_map_count = 300000),并且已经内存均是unlimited了,但是依旧如此报错。
oracle用户的ulimits设置如下
oracle@dcdb01:~> ulimit -a
core file size (blocks, -c) unlimited
data seg size (kbytes, -d) unlimited
scheduling priority (-e) 0
file size (blocks, -f) unlimited
pending signals (-i) 516185
max locked memory (kbytes, -l) unlimited
max memory size (kbytes, -m) unlimited
open files (-n) 65536
pipe size (512 bytes, -p) 8
POSIX message queues (bytes, -q) 819200
real-time priority (-r) 0
stack size (kbytes, -s) unlimited
cpu time (seconds, -t) unlimited
max user processes (-u) 16384
virtual memory (kbytes, -v) unlimited
file locks (-x) unlimited
系统参数如下:
dcdb01:~ # sysctl -p
net.ipv4.icmp_echo_ignore_broadcasts = 1
net.ipv4.conf.all.rp_filter = 1
fs.inotify.max_user_watches = 65536

net.ipv4.ip_local_port_range = 9000 65500

net.core.rmem_max = 4194304
net.core.wmem_default = 262144

alert日志在附件alertlog中
heapdump在附件dwdb_dw00_18121.rar中
cdmp和incident的日志也在附件中。
