Alter system switch logfile hang解决方法

关于数据库

alter system switch logfile hang住的解决方案

sys@ORA10G>alter system switch logfile;

alter system switch logfile

我只有ctrl+c 来暂停服务

sys@ORA10G>select dest_id,dest_name,status from v$archive_dest;

DEST_ID DEST_NAME STATUS

---------- -------------------------------------------------- ---------

1 LOG_ARCHIVE_DEST_1 INACTIVE

2 LOG_ARCHIVE_DEST_2 ERROR

3 LOG_ARCHIVE_DEST_3 INACTIVE

4 LOG_ARCHIVE_DEST_4 INACTIVE

5 LOG_ARCHIVE_DEST_5 INACTIVE

6 LOG_ARCHIVE_DEST_6 INACTIVE

7 LOG_ARCHIVE_DEST_7 INACTIVE

8 LOG_ARCHIVE_DEST_8 INACTIVE

9 LOG_ARCHIVE_DEST_9 INACTIVE

10 LOG_ARCHIVE_DEST_10 INACTIVE

发现，archive_dest_2有一个error 的错误提示。

sys@ORA10G>select * from v$log;

GROUP# THREAD# SEQUENCE# BYTES MEMBERS ARC STATUS FIRST_CHANGE# FIRST_TIM

---------- ---------- ---------- ---------- ---------- --- ---------------- ------------- ---------

4 1 6 10485760 1 NO CURRENT 3963939 12-OCT-12

确实，当前的日志组在group 4上面，所以，我在切换日志组的时候，也就是切换到group 2的时候，发现hang住了

我查看了alert日志

日志，这样描述的。

这样就解释了，log 2 文件没有被归档，是因为没有合适目录。

log 2 的没有归档，也导致了 log 3 也没有办法归档，也是因为没有合适的主目录。

知道了设置错误的归档路径，我们就好解决问题了

sys@ORA10G>alter system set log_archive_dest_2='location=/u01/ORCL/archivelog' scope=both;

System altered.

sys@ORA10G>show parameter log_archive_dest;

我们要重新应用新的归档路径，我们重启库。

这样，我们切换日志 没有任何问题。很好的解决了 switch log file 问题。
