oracle11g trace路徑和diagnostics路徑的變化

Oracle11g中trace檔案和日誌檔案的路徑發生了變化在$ORACLE_BASE/diag建立了一些分類目錄，用來儲存各種日誌：

[oracle@rac1 trace]$ cd $ORACLE_BASE
[oracle@rac1 oracle]$ cd diag
[oracle@rac1 diag]$ pwd
/u01/app/oracle/diag
[oracle@rac1 diag]$ ls
asm clients crs diagtool lsnrctl netcman ofm rdbms tnslsnr
[oracle@rac1 diag]$

其中rdbms儲存了使用者trace檔案，alertSID.ORA、後臺程式日誌等。

可以透過v$diag_info查詢這些資訊：

SQL> select * from v$diag_info;

INST_ID NAME VALUE
---------- ---------------------------------------- ------------------------------------------------------------------
1 Diag Enabled TRUE
1 ADR Base /u01/app/oracle
1 ADR Home /u01/app/oracle/diag/rdbms/orcl/orcl1

1 Diag Alert /u01/app/oracle/diag/rdbms/orcl/orcl1/alert
