Damaged indexes help!!!

  • Hi all,

    I got serious problem about index but i still don't know season why.

    Yesterday i came to my company and found an error in Window 2000 advanced server event log:

    Error: 7987, Severity: 22, State: 1

    A possible database consistency problem has been detected on database 'HRP'.  DBCC CHECKDB and DBCC CHECKCATALOG should be run on database 'HRP'.

    I run DBCC CHECKDB and found some red error:

    An index on table ... node.. error..

    Could you help me to find the reason and solution???

    My sql server had sp4 service pack already.

     

    Thanks

     

     

  • What's the exact error?? Hard to help you without that.

    Table error: Object DC_Errors  index  1013331120  Index node page 124452, slot 122345 refers to child page 124535 and previous child 122344, but they were not encountered.

    thanks

     

  • Good news. You've got an index allocation error. Easiest kind to fix. Drop the index and recreate it. Make sure you've got the recreate script handy prior to dropping of course.

    Keep an eye on the system. The occasional (read once every 18 months) allocation error is to be expected, anything more than that is an indication of a real problem; disks, fiber cards, etc..
