标题：安装19c 数据库 libclntsh.so: file format not recognized

今天在qq群里面,讨论一个19c(19.3)在linux系统(CentOS 7.9)安装的问题,感觉有点意思,给整理出来供参考
安装日志报错

INFO: 
/usr/bin/ld:/home/oracle/app/oracle/product/19.0.0/dbhome_1/lib//libclntsh.so: 
      file format not recognized; treating as linker script
/usr/bin/ld:/home/oracle/app/oracle/product/19.0.0/dbhome_1/lib//libclntsh.so:1: syntax error

INFO: 
make[2]: *** [dlopenlib] Error 1

INFO: 
make[2]: Leaving directory `/home/oracle/app/oracle/product/19.0.0/dbhome_1/rdbms/lib'

INFO: 
make[1]: Leaving directory `/home/oracle/app/oracle/product/19.0.0/dbhome_1/rdbms/lib'

INFO: 
make: *** [libasmperl19.ohso] Error 2

拿这个错误在mos上检索,发现匹配文章:19c Installation Fails with error “libclntsh.so: file format not recognized; treating as linker script” (Doc ID 2631283.1),结合文章分析,第一反应怀疑安装介质有问题,让网友进行sha256sum 验证

通过验证确认安装介质没有问题,和官方公布的一致.进一步检查 ls -l $ORACLE_HOME/libcln* 文件

这个问题比较明显,根据官方的描述,这些文件应该是:

这里比较明显对应的ln丢失了.从提供的以前unzip解压日志看

解压有这些文件,但是ln丢失,qq群朋友对unzip进行安装

然后重新解压oracle安装程序,验证libcln,一切正常,安装也成功

只可惜以前的unzip直接被安装新的unzip覆盖了,未做保留现场进行分析,为什么解压后ln丢失

标题：raid强制上线后数据库无法启动故障处理

由于raid掉盘过多,强制raid上线,然后启动数据库报以下错误

错误提示比较明显IO error,结合客户强行上线raid的操作,比较明显是由于底层io问题导致该错误,直接对此文件dbv检查

[oracle@database orcl]$ dbv file=dev02.dbf

通过对io error的文件进行处理,最终损坏三个block,最大限度抢救数据.使用被恢复出来的文件,尝试open库遭遇以下错误

SQL> alter database open resetlogs;
alter database open resetlogs

这个错误是比较常见的错误,参考:ORACLE Instance XFF (pid = 18) – Error 600 encountered while recovering transaction ，通过处理之后,数据库open成功
