AHF Installation Log : /tmp/ahf_install_2411000_64352_2026_07_24-09_51_32.log
[ERROR] : AHF-00005: Low disk space [837 MB] in AHF TMP Location [/tmp/.ahf.64352]. Need min 2048 MB of free space to install AHF
Please use -tmp_loc <dir> option where dir has more free space and try again



`/tmp` 剩余空间只有 837MB，**AHF 解压至少需要 2GB 空闲空间**，因此执行失败。
日志提示：使用 `-tmp_loc` 参数指定一个富余空间的目录替代 `/tmp`。

解决办法：
指定临时目录解压orachk (空间大于2G）
