原因
拥有Oracle安装的Unix用户的用户资源限制（例如'oracle'）是正确的，但拥有第三方应用的另一个Unix用户的用户资源限制（例如Patrol，由Unix用户'sapatrol'拥有）太低。
% ulimit -Sa
time(seconds) unlimited
file(blocks) 2097151
data(kbytes)
131072
stack(kbytes) 32768
memory(kbytes) 32768
coredump(blocks) 2097151
nofiles(descriptors) 2000
threads(per process) unlimited
processes(per user) unlimited
解决方案
增加拥有第三方应用的Unix用户的用户资源限制
要这么做，使用ulimit命令
例如，要将软'data' 和'stack' 限制设为unlimited ，使用命令：
% ulimit -d unlimited
% ulimit -s unlimited
要将硬'data' 和'stack' 限制设为unlimited ，使用命令：
% ulimit -Hd unlimited
% ulimit -Hs unlimited

Note:188149.1 或'ulimit' 手册页：
% man ulimit
