Hi,
I have several questions in Oracle server performance, any experts out
there could answer my questions. Thanks very much.
1) When I experience the Oracle server is very slow, which performance
view should I see in order to determine the caused? |
all V$ are performance views. v$sgastat, v$sesstat, v$session are
most important, but also verify server performance (ram,I/O,CPU)

2) How do I know if my SQL running in Oracle has sufficient resources |
v$session and some dictionary views are useful (dba_tables,
dba_segments, etc.) with dba_stats package to make statistics

V$session joined with V$sesstat
