执行perl xttdriver.pl报错Can't locate GetoptLong.pm in @INC

概述环境：AIX 6.1 + Oracle 10.2.0.4 现象：在做xtts测试时，源环境使用Oracle自带的perl执行xttdriver.pl报错如下： $ $ORACLE_HOME/perl/bin/perl xttdriver.plCan‘t locate Getopt/Long.pm in @INC (@INC contains: /project/aix5l64/main/APAC

环境：AIX 6.1 + Oracle 10.2.0.4
现象：在做xtts测试时，源环境使用Oracle自带的perl执行xttdriver.pl报错如下：

$ $ORACLE_HOME/perl/bin/perl xttdriver.plCan‘t locate Getopt/Long.pm in @INC (@INC contains: /project/aix5l64/main/APACHE/perl/bin/AIX/Opt/lib/5.8.3/aix-thread-multi /project/aix5l64/main/APACHE/perl/bin/AIX/Opt/lib/5.8.3 /project/aix5l64/main/APACHE/perl/bin/AIX/Opt/lib/site_perl/5.8.3/aix-thread-multi /project/aix5l64/main/APACHE/perl/bin/AIX/Opt/lib/site_perl/5.8.3 /project/aix5l64/main/APACHE/perl/bin/AIX/Opt/lib/site_perl .) at xttdriver.pl line 126.BEGIN Failed--compilation aborted at xttdriver.pl line 126.

而在目标环境linux6.8 + Oracle 11.2.0.4 就正常，起初我没多想这个问题，以为是10g的自带perl版本过低不支持，第一轮测试使用了系统自带perl可执行。
但在后续测试中发现系统自带的perl在执行过程中也是有很多类似错误，虽然最终完成，但担心有其他隐患，和有经验的同事进一步沟通，得知之前成功的xtts项目都是采用oracle自带的perl，某些版本报这个错误是需要额外设置环境变量。

具体依据下面的MOS文档，需要设置PER5liB环境变量：

perl xttdriver.pl fails: Can‘t locate Getopt/Long.pm in @INC (文档 ID 1912400.1)

临时设置PERL5liB环境变量：

$ export PERL5liB=$ORACLE_HOME/perl/lib

再次使用Oracle自带的perl执行xttdriver.pl不再报之前的错误，这里测试没加参数，就正常列出了xttdriver.pl的使用方法：

既然如此，后续还是建议使用oracle自带的perl进行测试。
