搭建oracle12c备机过程中发现sqlplus登陆报错如下:
[xdhsdb@oracle:/oracle]$sqlplus
exec(): 0509-036 Cannot load program sqlplus because of the following errors:
0509-130 Symbol resolution failed for /oracle/app/oracle/product/12.2.0/dbhome_1/lib/libons.so because:

0509-026 System error: Error 0
0509-192 Examine .loader section symbols with the
'dump -Tv' command.
因为笔者之前是解压缩tar包的方式安装oracle的,都没有问题。搜索了网上都是系统相关问题
检查了iocp参数果然没有改
[xdhsdb@oracle:/oracle]$lsdev |grep iocp
iocp0 Defined I/O Completion Ports
修改参数重启后解决问题
[xdhsdb@root:/]#chdev -l iocp0 -P -a autoconfig='available';
iocp0 changed
总结:
因为该备机的rootvg笔者是通过克隆方式拷贝过来的,虽然克隆原机参数修改了,但是克隆之后发现这个参数会被重置为默认状态。
另外一些系统参数也需要修改并重启
chdev -l sys0 -a maxuproc=16384
chdev -l sys0 -a maxbuf=500
