Oracle Executables

This table lists executable programs in $ORACLE_HOME/bin (or %ORACLE_HOME%\bin on Windows) for Oracle Enterprise Edition, including shell scripts, Windows .bat files but excluding Windows DLLs or any that can't execute directly. It's not a complete list since what programs are in that directory depends on what options I chose at the time of software installation. I'm doing my best to give descriptions about each program and add some comments I consider useful or merely interesting. Many of them show Usage by typing the program name, or the name followed by some garbage argument, or -h, or sometimes help=y. "Not in 9i" means not in 9i and up (i.e. only in 8i). Files of 0 in size are ignored, such as tnnfg, trcldr (not any more in 12.1.0.2), plus those whose names end with 0 or O.

nidDB New IDChange DBID so a database cloned using the traditional method (instead of DUPLICATEd by RMAN) can register with the same RMAN catalog as the source DB. The syntax is nid target=sys/syspassword. (It's not nid target="sys/syspassword as sysdba" even if you need as sysdba for sqlplus). After running nid, you have to open resetlogs, and database resetlogs time and v$thread.enable_time will both be updated.

oracle Oracle RDBMS Kernel Executable On UNIX, if dedicated configuration, every client process such as sqlplus or Toad, connects to tnslsnr, which fork()'s and then exec()'s oracle kernel program, $ORACLE_HOME/bin/oracle. The oracle process thus created is called a server process, or a shadow process to emphasize the client-server two-task nature. This server process is renamed to oracleSID (DESCRIPTION=(LOCAL=... for easy identification and troubleshooting. But its program (process text) is still this oracle binary. You should never directly run this binary; or you may get ORA-600 [12235] (see Note:33174.1; true for pre-11g). Oracle does not recommend changing the process priority. But some tests conclude it may improve DBWn performance if its priority is increased. You should also avoid stripping the oracle binary or you'll lose symbol information in trace files. But you can certainly run nm on it to get symbols such as sgabeg in this file. You can find all undocumented SQL hints by running strings on it, but 11g provides v$sql_hint view.

On Windows, there's always only one oracle.exe process for one instance. Each server "process" is just a Windows thread inside this process. If you have multiple Oracle instances running in Windows, you can identify the process for a specific instance with tools such as tlist. Oracle supports changing process priority on Windows.

orajaxbOracle Java Architecture for XML Binding10g. XML JAXB Class Generator. Replacing oracg in 9i. Ref
orakill*Usage: orakill instance_name v$process.spid. Used to kill a specific thread inside oracle.exe process. Apparently orakill does a little more than just killing the thread because using a non-Oracle tool such as Sysinternals's Process Explorer to kill a thread in oracle.exe doesn't always make a hanging session and its lock go away; you may have to manually run oradebug wakeup 1 to wake up pmon (which should clear the lock and v$session / v$process, but the client app may still hang). If you can't run orakill for any reason, use a tool like Process Explorer, followed by manual pmon wakeup.

orastack*Oracle Stack modificationUsed to resize the stack of an Oracle executable file such as oracle.exe, tnslsnr.exe (one way of preventing ORA-12500). Type the command at DOS to see an excellent description. (Not equivalent to pstack available on some UNIXes used to dump stack trace of a running process, but more like Solaris command ppgsz -o stack=... except it works on file not process)
oratclshOracle TCL ShellTCL programming language shell for Oracle. In spite of Oracle's advocacy, few people actually used it and now it's silently deprecated by Oracle, probably in favor of Perl.
