DB2IMIGR SETS INCORRECT PERMISSIONS FOR KERBEROS CATALOG DIRECTORIES IN SQLDBDIR (SQLKRB) |
| Produkt: |
DB2 FOR LUW / DB2FORLUW / 910 - DB2 |
| Problembeschreibung: |
When we have a database catalogued as using Kerberos
authentication, the migration from v8 to v9.x will render the
catalog directory unusable
To reproduce:
1.
$ db2 catalog tcpip node thost remote thost server 50000
DB20000I The CATALOG TCPIP NODE command completed successfully.
DB21056W Directory changes may not be effective until the
directory cache is
refreshed.
$ db2 catalog database tkerb as tkerb at node thost
authentication kerberos target principal db2@thost.db2lab.com
DB20000I The CATALOG DATABASE command completed successfully.
DB21056W Directory changes may not be effective until the
directory cache is
refreshed.
$
/home/db2inst9/sqllib/sqldbdir
$ ls -al
total 16
drwxrwxr-x 3 db2inst9 db2iadm9 512 Dec 3 13:29 .
drwxrwxr-t 18 db2inst9 db2iadm9 1024 Dec 3 13:29 ..

drwxrwxr-x 2 db2inst9 db2iadm9 512 Dec 3 13:29 sqlkrb
$ ls -al sqlkrb
total 6
drwxrwxr-x 2 db2inst9 db2iadm9 512 Dec 3 13:29 .
drwxrwxr-x 3 db2inst9 db2iadm9 512 Dec 3 13:29 ..
-rw-rw-r-- 1 db2inst9 db2iadm9 32 Dec 3 13:29 TKERB
2.
After running db2imigr the permissions show incorrect. In
certain cases this directory could be corrupt
/home/db2inst9/sqllib/sqldbdir
$ ls -al
total 22
drwxrwxr-x 3 db2inst9 db2iadm9 512 Dec 3 13:36 .
drwxrwxr-t 19 db2inst9 db2iadm9 1024 Dec 3 13:36 ..
-rw-rw-r-- 1 db2inst9 db2iadm9 1512 Dec 3 13:36 sqldbbak
-rw-rw-r-- 1 db2inst9 db2iadm9 1512 Dec 3 13:36 sqldbdir
-rw-rw-r-- 1 db2inst9 db2iadm9 540 Dec 3 13:36 sqldbins
-rw-rw-r-- 1 db2inst9 db2iadm9 2148 Dec 3 13:36
sqldddir.bak
drw-rw-r-- 2 db2inst9 db2iadm9 512 Dec 3 13:29 sqlkrb
3. Running db2 list database directory will throw error
SQL10004C and db2diag.log will show access permission errors on
sqlkrb
$ db2 list database directory
System Database Directory
Number of entries in the directory = 1
SQL10004C An I/O error occurred while accessing the database
directory.
SQLSTATE=58031
FUNCTION: DB2 Common, OSSe, ossErrorIOAnalysis, probe:100
CALLED : OS, -, open
OSERR : EACCES (13) "Permission denied"
DATA #1 : String, 141 bytes
A total of 2 analysis will be performed :
- User info
- Path access permission
Target file = /home/db2inst9/sqllib/sqldbdir/sqlkrb/TKERB
DATA #2 : String, 184 bytes
Real user ID of current process = 221
Effective user ID of current process = 221
Real group ID of current process = 111
Effective group ID of current process = 111
DATA #3 : String, 328 bytes
Information of each subdirectory leading up to the first
inaccessible one is shown in the format below :
<UID>:<GID>:<permissions> (subdirectories)
0:0:755 (home)
221:111:755 (db2inst9)
221:111:1775 (sqllib)
221:111:775 (sqldbdir)

****************************************************************
* RECOMMENDATION: *
* Upgrade to DB2 Version 9.1 Fix Pack 9 *
**************************************************************** |
| Local-Fix: |
Uncatalog databases that use Kerberos authentication previous to
running db2imigr and catalog them again afterwards.
If already have run db2imgr and the directory sqlkrb shows wrong
permissions run chmod ug=rwx,o=rx. |
