。。。。很多这样can't recover from rollback of multi-chunk txn, aborting..

同时后台trc文件一直在增长
[ bdump]$ ll | grep 6808
-rw-r-----   1 oracle     dba        2315045139 Mar 15 21:11 orapay_p001_6808.trc
[bdump]$ ll | grep 6808
-rw-r-----   1 oracle     dba        2315185055 Mar 15 21:14 orapay_p001_6808.trc
[ bdump]$ ll | grep 6808
-rw-r-----   1 oracle     dba        2315186633 Mar 15 21:14 orapay_p001_6808.trc

谢谢解答下。

ODM FINDING:

  1. Starting Captures produces trace: Cannot Resolve Kxidsqn For Lcr

  2. Applies to:
  3. Oracle Server - Enterprise Edition
  4. Information in this document applies to any platform.
  5. Symptoms

  6. When starting a capture process, trace files are being generated. The contents looks like this:

  7. Cannot resolve kxidsqn for lcr:
  8. ++ LCR Dump Begin: 0x700000108320d98
  9. operation: 26, bobjn: 0 objn: 12986, objv: 0,

  15. LUBA: 0x46.1180a19c.2c.50.32ba






  16. Changes
  17. Cause

  18. This is an informational warning on capture restart from Unpublished Bug 8502190
  19. The message can be ignored or suppressed by setting an event in the init.ora

  20. Solution

  21. To turn this particular warning trace off ,set the event 1349 in the init.ora file.


  22.    event="1349 trace name context forever, level 1048576"



  23. Then bounce the instance.
复制代码




如果LOGICAL STANDBY的使用正常的话 ,一般可以忽略这些警告 ,也可以通过 设置1349 EVENT来 关闭这些告警的产生:

ALTER SYSTEM SET event='1349 trace name context forever, level 1048576'   scope=spfile;

REBOOT INSTANCE
