LTOM和上一篇文章提到的OSW工具类似，都是oracle提供的一个诊断工具，不过OSW是基于OS层面的信息统计，LTOM则倾向于统计数据库的相关信息，结合这2个诊断工具，可以给DBA减少不少的工作量。和OSW一样，LTOM同样支持多平台：Solaris,Linux,HP-UX,AIX,Tru64. 目前最新版本是4.3.1，文章末尾有下载地址。下面简单是来看一下LTOM的安装和使用。
1. 上传LTOM安装包到服务器，并解压（上传的路径最好是在$ORACLE_HOME下面）

2. 解压之后会得到ltom目录，进入到tom_base目录，可以看到有2个目录，一个是install，另一个是tom，还有一个README的文件，可以查看README文件进行安装，首先进入Install目录，运行autoinstall.sh脚本自动安装ltom，这里需要注意的是，在运行这个自动安装的脚本之前，一定要给当前用户配置3个环境变量：java的环境变量，ORACLE_HOME, ORACLE_SID, TOM_HOME。

----------------------------我这里配置的环境变量如下，我使用的是oracle用户安装，不然等下无法创建tom数据库用户，因为需要管理员的权限 export ORACLE_BASE=/opt/oracle export ORACLE_HOME=/opt/oracle/product/12.1/db_1 export ORACLE_SID=ora12c130 export JAVE_HOME=/opt/oracle/product/12.1/db_1/jdk/jre export PATH=/opt/oracle/product/12.1/db_1/jdk/jre/bin:$PATH:HOME/bin:$ORACLE_HOME/bin export TOM_HOME=/opt/oracle/ltom/tom_base/tom ----------------------------然后运行autoinstall.sh脚本 oracle@linux-fz9d:~/ltom/tom_base/install> ./autoinstall.sh TOM_HOME=/opt/oracle/ltom/tom_base/install/../tom rm: cannot remove `autoinstall.log': No such file or directory Preparing to install LTOM v4.3.0...

3. 配置完成后，如果需要修改采集配置，在ltom/tom_base/tom/init目录下可以看到相关的配置文件，可以按需修改
| 1 2 3 4 5 6 7 8 |
oracle@linux-fz9d:~/ltom/tom_base/tom/init> ll total 20 -rw-r--r-- 1 oracle oinstall 3619 Oct 4 2007 dataCollect.properties -rw-r--r-- 1 oracle oinstall 7087 Oct 6 2007 hangDetect.properties -rw-r--r-- 1 oracle oinstall 3544 Oct 6 2007 sessionRecorder.properties -rw-r--r-- 1 oracle oinstall 3956 Mar 27 12:39 tom_deploy.properties oracle@linux-fz9d:~/ltom/tom_base/tom/init> pwd /opt/oracle/ltom/tom_base/tom/init |
4. 配置完成后，就可以执行startltom.sh脚本了，在执行这个脚本的时候，需要输入tom数据库用户，但可能你会遇到一个ORA-28040: No matching authentication protocol错误，这是由于没有匹配的身份认证协议，是JDBC一个常规的错误，这时候需要将sqlnet.ora里的SQLNET.ALLOWED_LOGON_VERSION值设置为8，我这里设置为8后，就可以连接成功了。
