oracle sqlldr -> 未定义符号：sldext

Question

1. 已安装oracle_client

   • oracle-instantclient11.2-basic-11.2.0.4.0-1.x86_64.rpm
   • oracle-instantclient11.2-devel-11.2.0.4.0-1.x86_64.rpm
   • oracle-instantclient11.2-sqlplus-11.2.0.4.0-1.x86_64.rpm

2. 复制sqlldr文件到/usr/lib/oracle/11.2/client64/bin

3. 将rdbms,nls文件夹复制到/usr/lib/oracle/11.2/client64/

4. 设置.bash_profile

   export LANG=en_US.UTF-8
   export ORACLE_HOME=/usr/lib/oracle/11.2/client64
   export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ORACLE_HOME/lib
   export NLS_LANG=KOREAN_KOREA.KO16KSC5601
   export TNS_ADMIN=$ORACLE_HOME/network/admin
   export ORA_NLS10=$ORACLE_HOME/nls/data
   export PATH=$ORACLE_HOME/bin:$PATH
   

但是，执行ldd -r sqlldr 跟随下一行

linux-vdso.so.1 =>  (0x00007fff03fff000)
        libclntsh.so.11.1 => /usr/lib/oracle/11.2/client64/lib/libclntsh.so.11.1 (0x00007f6f036bb000)
        libnnz11.so => /usr/lib/oracle/11.2/client64/lib/libnnz11.so (0x00007f6f032ed000)
        libpthread.so.0 => /lib64/libpthread.so.0 (0x00000037fae00000)
        libdl.so.2 => /lib64/libdl.so.2 (0x00000037fa600000)
        libm.so.6 => /lib64/libm.so.6 (0x00000037fb600000)
        libnsl.so.1 => /lib64/libnsl.so.1 (0x00000037fce00000)
        libc.so.6 => /lib64/libc.so.6 (0x00000037faa00000)
        libaio.so.1 => /lib64/libaio.so.1 (0x00007f6f030e0000)
        /lib64/ld-linux-x86-64.so.2 (0x00000037fa200000)
undefined symbol: sldext        (./sqlldr)
undefined symbol: sldextf       (./sqlldr)

.bash_profile

export LANG=en_US.UTF-8
export ORACLE_HOME=/usr/lib/oracle/11.2/client64
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ORACLE_HOME/lib
export TNS_ADMIN=$ORACLE_HOME/network/admin
export ORA_NLS10=$ORACLE_HOME/nls/data
export PATH=$ORACLE_HOME/bin:$PATH

如何删除undefined symbol？

Answer 1

问题出在以下库：

/usr/lib/oracle/11.2/client64/lib/libclntsh.so.11.1

将此库更改为旧版本即可。 我们看到 11.2.0.4 版本的库会抛出此错误，而 11.2.0.3 版本则正常工作。
