V$PROCESS

V$PROCESS 展示当前数据库的活动进程信息。

Column	Datatype	Description
`ADDR`	`RAW(4 \| 8)`	Address of the process state object
`PID`	`NUMBER`	Oracle process identifier
`SOSID`	`VARCHAR2(24)`	Operating system (process, thread) identifier. This identifier is unique whether the Oracle multiprocess/multithread feature is enabled or not.
`SPID`	`VARCHAR2(24)`	Operating system process identifier. The Oracle multiprocess/multithread feature is available for UNIX systems. When the Oracle multiprocess/multithread feature is enabled, RDBMS processes are mapped to threads running in operating system processes, and the `SPID` identifier is not unique for RDBMS processes. When the Oracle multiprocess/multithread feature is not enabled on UNIX systems, the `SPID` identifier is unique for RDBMS processes.
`STID`	`VARCHAR2(24)`	Operating system thread identifier. The Oracle multiprocess/multithread feature is available for UNIX systems. When the Oracle multiprocess/multithread feature is enabled, RDBMS processes are mapped to threads running in operating system processes, and the `SPID` and `STID` together uniquely identify an RDBMS process. The `STID` is not unique on Solaris. The `STID` is unique on Linux and AIX.
`EXECUTION_TYPE`	`VARCHAR2(10)`	Operating system execution type
`PNAME`	`VARCHAR2(5)`	Name of this process
`USERNAME`	`VARCHAR2(15)`	Operating system process username
`SERIAL#`	`NUMBER`	Process serial number
`TERMINAL`	`VARCHAR2(30)`	Operating system terminal identifier
`PROGRAM`	`VARCHAR2(48)`	Program in progress
`TRACEID`	`VARCHAR2(255)`	Trace file identifier
`TRACEFILE`	`VARCHAR2(513)`	Trace file name of the process
`BACKGROUND`	`VARCHAR2(1)`	`1` for a background process; NULL for a normal process
`LATCHWAIT`	`VARCHAR2(16)`	Address of the latch the process is waiting for; NULL if none
`LATCHSPIN`	`VARCHAR2(16)`	This column is obsolete
`PGA_USED_MEM`	`NUMBER`	PGA memory currently used by the process (in bytes)
`PGA_ALLOC_MEM`	`NUMBER`	PGA memory currently allocated by the process (including free PGA memory not yet released to the operating system by the server process), in bytes
`PGA_FREEABLE_MEM`	`NUMBER`	Allocated PGA memory which can be freed (in bytes)
`PGA_MAX_MEM`	`NUMBER`	Maximum PGA memory ever allocated by the process (in bytes)
`CON_ID`	`NUMBER`	The ID of the container to which the data pertains. Possible values include: `0`: This value is used for rows containing data that pertain to the entire CDB. This value is also used for rows in non-CDBs. `1`: This value is used for rows containing data that pertain to only the root n: Where n is the applicable container ID for the rows containing data
