Transaction recovery: lock conflict caught and ignored

ALERT.LOG:

..... Transaction recovery: lock conflict caught and ignored
.....

And also some incident files are being created in $ORACLE_BASE/diag/rdbms/dbname/instancename/incident folder.

In my case the error started after SUPPLEMENTAL LOGGING enabled in a RAC environment. After disabling it the messages have not disappeared, but incident files are no longer being created.

1. Dead Trasaction

SQL> select b.name useg, b.inst# instid, b.status$ status, a.ktuxeusn

xid_usn, a.ktuxeslt xid_slot, a.ktuxesqn xid_seq, a.ktuxesiz undoblocks,

a.ktuxesta txstatus

from x$ktuxe a, undo$ b

where a.ktuxecfl like ‘%DEAD%’

and a.ktuxeusn = b.us#;

USEG INSTID STATUS XID_USN XID_SLOT XID_SEQ UNDOBLOCKS TXSTATUS
_SYSSMU7_881277423$ 1 3 7 13 1829999 1 ACTIVE
_SYSSMU8_4204495590$ 1 3 8 32 3045564 1 ACTIVE
_SYSSMU10_1314081219$ 1 3 10 3 11844457 1 ACTIVE

Transaction id is  XID_USN.XID_SLOT.XID_SEQ

So in our case, for the first row it will be 7.13.1829999

2.  Read transaction table from undo header.

ALTER SYSTEM DUMP UNDO HEADER ‘_SYSSMU7_881277423$’;

KDO undo record:

irb points to last UNDO RECORD in UNDO block.

rci points to previous UNDO RECORD. if rci=0, it’s the first UNDO RECORD.

Recovery operation starts from irb and chain is followed by rci until rci is zero.

The transaction starts recovery from UNDO RECORD of 0x5.

Automatic Tablespace Point-in-Time Recovery(TSPIR) in Oracle 11gR2

Automatic tablespace point-in-time recovery is very useful in the following situations:

1.  You want to recover just one tablespace to the point in time other than rest of the tablespaces.

2. You want to recover dropped tablespace.

3. You want to recover data in table that was lost after changing structure of the table. Note that you are not able to use Flashback Table feature to recover data that was lost after changing table structure, it is not permitted.

TSPITR has a number of restrictions, a quick summary of which follows:

1.  You can’t restore tablespaces with objects owned by SYS. Any tablespace with replicated master tables cannot be recovered with TSPITR.

2. Tablespaces with snapshot logs are not supported.

3. You can’t restore tablespaces that contain rollback segments.

4. If an object within the tablespace to be recovered has one of the following types, then TSPITR is not supported:

    1. VARRAY
    2. Nested tables 
    3. External files

5. The current physical structure of the undo and rollback segments in the target database
must be unchanged between the point you wish to recover to and the current point.

6. Once you have completed TSPITR on a given tablespace, all previous backups of that tablespace are no longer usable for future TSPITR recoveries of that tablespace. So you should backup your tablespace after TSPITR in case you need to run another TSPITR.

So, let’s start automatic TSPITR…Note that we are not using recovery catalog.

1. Identify the time to which you want to recover your tablespace. Don’t misidentify the time or you will not be able to retry the recovery.(As we mentioned in the section 6 of TSPITR restrictions, all previous backups will no longer be usable for future TSPITR)

2. Make sure that objects in that tablespace are self-contained.

Let’s say we have the tablesapace called “TEST”.  It contains table “TEST_TABLE” but indexes on that table resides on another tablespace called “TEST_IDX”. In this case, if you want to recover “TEST” tablespace to some point-in-time , then you must also recover “TEST_IDX” tablespace to the same point-in-time(or you will loose indexes).

To identify dependent tablesapaces, run the following:

SQL> select obj1_owner
       ,obj1_name
       ,obj1_type
       ,ts2_name
       ,reason
from sys.ts_pitr_check
where ( ts1_name in (‘TEST’)
and ts2_name not in (‘TEST’) )
or ( ts1_name not in (‘TEST’)
and ts2_name in (‘TEST’) );

OBJ1_OWNER OBJ1_NAME  OBJ1_TYPE TS2_NAME REASON
TEST_USR       TEST_TABLE TABLE           TEST_IDX Tables and associated indexes not fully contained in the recovery set

This would return no rows if there were no dependencies. If there were any, you would see a
row describing each of them, as shown above.

In our case, there is an index associated with TEST_TABLE table and it resides in TEST_IDX tablespace. We should restore it also.

3. Identify what objects will be dropped after recovering tablespace.

Run the following,

SQL> select *
from ts_pitr_objects_to_be_dropped
where tablespace_name=’TEST’

OWNER NAME CREATION_TIME TABLESPACE_NAME
TEST_USR TEST_TABLE 4/19/2013 12:19:18 PM TEST

For example, if you are going to recover tablespace to 4/19/2013 12:00:00PM  then TEST_TABLE will be dropped.

4. Start test case.

Now we create 2 tablespaces TEST and TEST_IDX . Create TEST_USR user. Create TEST_TABLE table in TEST tablespace and TEST_INDEX in TEST_IDX. Fill table with data. Backup database. Before dropping table we save current SCN and then  drop table. We will do TBSPIR until the saved SCN.

Step 0 :  Clean the previous failed TSPIR

SQL> exec dbms_backup_restore.manageauxinstance (‘instance_name’,1) ;

instance_name will be generated automatically, and you should see it in RMAN output.

Step 1. Create TEST and TEST_IDX tablespaces.

SQL> CREATE TABLESPACE TEST DATAFILE
  ‘D:\APP\ORACLE\ORADATA\ORCL\TEST.DBF’ SIZE 104857600
  AUTOEXTEND ON NEXT 1048576 MAXSIZE 32767M;
 
  SQL> CREATE TABLESPACE TEST_IDX DATAFILE
  ‘D:\APP\ORACLE\ORADATA\ORCL\TEST_IDX.DBF’ SIZE 104857600
  AUTOEXTEND ON NEXT 1048576 MAXSIZE 32767M; 

Step 2. Create TEST_USR user, grant privileges.

SQL> CREATE USER TEST_USR IDENTIFIED BY TEST
DEFAULT TABLESPACE TEST;

SQL> GRANT CONNECT,RESOURCE TO TEST_USR;

Step 3. Create TEST_TABLE table.

SQL> CREATE TABLE TEST_USR.TEST_TABLE(A DATE);

Step 4. Create TEST_INDEX index.

SQL> CREATE INDEX TEST_USR.TEST_INDEX
ON  TEST_USR.TEST_TABLE(A)
TABLESPACE TEST_IDX;

Step 5. Fill data.

SQL> INSERT INTO TEST_USR.TEST_TABLE
VALUES(SYSDATE);

SQL> INSERT INTO TEST_USR.TEST_TABLE
VALUES(SYSDATE);

SQL> COMMIT;

Step 6.

SQL> SELECT *
FROM TEST_USR.TEST_TABLE

A
4/19/2013 12:20:16 PM
4/19/2013 12:20:16 PM

Step 7. Backup database.

RMAN> backup database plus archivelog;

Step 8.  Note the current SCN.

SQL> SELECT CURRENT_SCN
FROM V$DATABASE

CURRENT_SCN
2091595

Step 9. Drop table.

DROP TABLE TEST_USR.TEST_TABLE

Step 10. Create tables in SYSTEM and TEST_IDX tablespaces.

SQL> CREATE TABLE TEST_USR.TEST_USR_SYSTEM(A DATE)
TABLESPACE SYSTEM;

SQL> INSERT INTO TEST_USR.TEST_USR_SYSTEM VALUES(SYSDATE);

SQL> COMMIT;

SQL> CREATE TABLE TEST_USR.TEST_USR_TEST_IDX(A DATE)
TABLESPACE TEST_IDX;

SQL> INSERT INTO TEST_USR.TEST_USR_TEST_IDX VALUES(SYSDATE);

SQL> COMMIT;

This is just for to see that just TEST and TEST_IDX tablespaces are affected. And not SYSTEM or any other tablespaces. Smile

Step 11. Do TSPIR.

Note: Auxiliary destination must already exist and oracle software owner must be able to write into it.

!!! You should recover dependent tablespaces also , or data in these tablespaces will be lost.

For example: If you just recover TEST tablespace, then index on TEST_TABLE will be lost(resides in TEST_IDX tablespasce)… Note also that if you try to recover just TEST_IDX tablespace it will cause the following error:

The transportable set is not self-contained, violation list is Index TEST_USR.TEST_INDEX in tablespace TEST_IDX points to table TEST_USR.TEST_TABLE in tablespace TEST.

!!! Recoverable tablespaces must not contain SYS objects, or it will fail.

!!! Identify the exact point of time or after recovering tablespace, you will not be able to re-run TSPIR by existing backups.

After recovering tablespaces, if you run list backup command:

RMAN> list backup;

File LV Type Ckp SCN    Ckp Time            Name
—- — —- ———- ——————- —-
1       Full 2084320    19-04-2013 16:52:21 D:\APP\ORACLE\ORADATA\ORCL\SYSTEM01.DBF
2       Full 2084320    19-04-2013 16:52:21 D:\APP\ORACLE\ORADATA\ORCL\SYSAUX01.DBF
3       Full 2084320    19-04-2013 16:52:21 D:\APP\ORACLE\ORADATA\ORCL\UNDOTBS01.DBF
4       Full 2084320    19-04-2013 16:52:21 D:\APP\ORACLE\ORADATA\ORCL\USERS01.DBF
5       Full 2084320    19-04-2013 16:52:21
6       Full 2084320    19-04-2013 16:52:21

There are empty strings across recovered tablespaces.

So after TSPIR , you must re-take backup of the recovered tablespaces.

Multipath configuration on RHEL6

1. Check if you have already installed device-mapper-multipath rpm, if not then install it.

rpm -qa device-mapper-multipath

2. If /etc/multipath.conf file doesn’t exist, then copy it from /usr/share/doc/device-mapper-multipath-*

cp /usr/share/doc/device-mapper-multipath-0.4.9/multipath.conf /etc/multipath.conf

3. Find WWIDs that should be added to multipath configuration.

# scsi_id -g -u /dev/sdb
36001438009b044d90000900000780000

4. Edit the /etc/multipath.conf configuration file

defaults {
        user_friendly_names yes
        path_grouping_policy    failover
}

blacklist {
        wwid "*"
}

blacklist_exceptions {
        wwid "36001438009b044d90000900000780000"
}

multipaths {
        multipath {
                wwid                    "36001438009b044d90000900000780000"
                alias                   asm1
        }
}

5.  Add module to the Linux kernel:

modprobe dm-multipath

6. Start multipath service:

service multipathd start

7. If you have any syntax errors or any parameters that do not work in your Linux version, the following command will show:

multipath -d

8. Commit the configuration:

multipath -v2

9. The following command must find the paths , or you have a bad configuration in multipath.conf file:

multipath -ll

10. Make devices configured after a reboot:

chkconfig multipathd on

If you have made any mistakes in multipath.conf file then correct them and do  the following steps to make changes take affect :

1. edit the /etc/multipath.conf

2.  Reload the multipath service:

service multipathd reload

3.  Remove all unused multipath devices

multipath -F

4.  Check again that syntax is correct:

multipath –d

5.  Commit the changes:

multipath –v2

Note that, this configuration is very simple, but it is working also perfectly.

For more multipath options and more sophisticated configuration, see the following documentation.

Installation problem of OEL6 on HP ProLiant DL360e Gen8 with HP Dynamic Smart Array B320i Controller

This post is dedicated to the Oracle Enterprise Linux 6.x installation on HP server with Dynamic Smart Array B320i Controller.

Brief description of the problem:

During OEL6 installation on HP server installer was not able to see local disks, on which system should be installed. Local disk specification was the following: Two 300GB disks involved into the RAID 1 and controller for RAID was Dynamic Smart Array B320i.

Installer was able to see multipath devices and any other external devices, like flash drive, but not local disks.

On HP site, there is written that the minimum supported Oracle Linux updates for HP  DL380e series are the following:

DL380e Gen8

  • Oracle Linux/UEK 6.2
  • Oracle Linux/UEK 5.8

Minimum support includes all future updates of the indicated release unless a maximum is listed. (Example: Oracle 6 implies support for Oracle 6.x, unless it’s specifically called out in the notes as "not supported with 6.x")”

And HP also declaims that it gives its drivers to the supported OSs manufacturers.

To tell the truth, I’ve tried Oracle Enterprise Linux 5.5, 6.0, 6.2 and 6.4 versions, but none of them was able to see the local storage.

After a lot of troubleshooting, I found the solution.

Solution:

The solution implies the HP Dynamic Smart Array SATA RAID Controller Driver for Red Hat Enterprise Linux 6 installation before OS installation.

1. Download drivers from the following link, click here.

Note: hpvsa-1.2.4-4.rhel6u1.x86_64.dd.gz is for RHEL6.1
hpvsa-1.2.4-4.rhel6u2.x86_64.dd.gz is for RHEL6.2
hpvsa-1.2.4-4.rhel6u3.x86_64.dd.gz is for RHEL6.3

Because of we are installing Oracle Enterprise Linux 6.2 which is based on RHEL6.2, we need hpvsa-1.2.4-4.rhel6u2.x86_64.dd.gz.

2. Extract gz file, you should have file with the extension of dd. Write this file to the flash drive and connect it to the server.

3. Put Oracle Enterprise Linux 6.2 installation disk and when the following window appears, press the TAB.

At the end of the command write install dd(separated from the previous command with space) and press Enter.

4. Choose the driver file, that we mentioned earlier and continue the installation.

Oracle EL should now see the local disk without any problem. Good Luck.

Configure SSL Connections on Report Server(https)

You must have a server certificate installed on the computer. Ask for the certificate to your sysadmins(windows admins), or request a certificate from a trusted certificate authority.

The following steps do not include instructions for requesting, generating, downloading, or installing a certificate. You must have a certificate installed and available to use.

So let’s start.

1. Run Reporting Services Configuration Manager and connect to the reporting server.

2. In Web Service URL section –> SSL Certificate –> choose your certificate –> click Apply.

3. Report Manager URL section –> Advanced button –> Multiple SSL identities for Report Manager section –>

click Add button –> in Certificate choose your certificate and click OK –> OK.

4. Stop and Start your Reporting service, from the first section of the configuration manager.

5. Check that the URL works by indicating https instead of http.
