Oracle Internal : 通过 oradebug 获取内核的编码命令

在 Oracle 数据库,复杂的内核调用往往让读者迷惑，然而，Oracle 提供了丰富的接口去获取信息，例如 oradebug doc 命令。

Use <component_name>, <library_name> or <library_name>.<component_name>

以下是ASM 的范例（11.2.0.4版本）：

SQL> oradebug doc component asm asm

  ASM			       Automatic Storage Management (kf)
    KFK 		       KFK (kfk)
      KFKIO		       KFK IO (kfkio)
      KFKSB		       KFK subs (kfksubs)
    KFN 		       ASM Networking subsystem (kfn)
      KFNU		       ASM Umbillicus (kfnm, kfns, kfnb)
      KFNS		       ASM Server networking (kfns)
      KFNC		       ASM Client networking (kfnc)
    KFIS		       ASM Intelligent Storage interfaces (kfis)
    KFM 		       ASM Node Monitor Interface Implementation (kfm)
      KFMD		       ASM Node Monitor Layer for Diskgroup Registration (kfmd)
      KFMS		       ASM Node Monitor Layers Support Function Interface (kfms)
    KFFB		       ASM Metadata Block (kffb)
    KFFD		       ASM Metadata Directory (kffd)
    KFZ 		       ASM Zecurity subsystem (kfz)
    KFC 		       ASM Cache (kfc)
    KFR 		       ASM Recovery (kfr)
    KFE 		       ASM attributes (kfe)
    KFDP		       ASM PST (kfdp)
    KFG 		       ASM diskgroups (kfg)
    KFDS		       ASM staleness registry and resync (kfds)
    KFDX		       ASM Exadata interface (kfdx)

以下是 12c 的版本输出：
