Alter database link Password 11g
Our organization requires a regular password change on some database accounts for security compliance. If this account is used in the database link in other database, that database link has to be dropped and recreated with an updated password.
This changes in 11gR2 because it now offers the alter database link to change password. No more drop and recreate database link!
Sample here is on the database where database link is located:
The password of the database link’s account has just been changed.
db11gr2 SQL> select count(*) from tb_test@DL_TEST;
select count(*) from tb_test@DL_TEST
*
ERROR at line 1:
ORA-01017: invalid username/password; logon denied
ORA-02063: preceding line from DL_TEST
db11gr2 SQL> alter database link DL_TEST connect to dblink_test identified by dblink_test;
Database link altered.
db11gr2 SQL> select count(1) from tb_test@DL_TEST;
COUNT(1)
----------
6304
This option is not available in the pre-11gR2.
db11gr1 SQL > alter database link DL_TEST connect to dblink_test identified by dblink_test;
alter database link DL_TEST connect to dblink_test identified by dblink_test
*
ERROR at line 1:
ORA-02231: missing or invalid option to ALTER DATABASE

ORACLE 11G work with IPv6 addresses in addition to IPv4
ORACLE 11G work with IPv6 addresses in addition to IPv4
These are the simple steps that will make your DB 11g instance work with IPV6 environment.
Configure Linux
To configure Linux with this specific IPv6 address, you modify the /etc/sysconfig/network-scripts/ifcfg-{device name} file.
In my case I modified the ifcfg-eth0 file. I had previously added an IPv6 address and will add a secondary IPv6 address for the IPv4 Mapped Address.
DEVICE=eth0
BOOTPROTO=none
ONBOOT=yes
HWADDR=00:50:43:ac:11:a2
TYPE=Ethernet
USERCTL=no
IPV6INIT=yes
PEERDNS=yes
NETMASK=255.255.0.0
IPADDR=192.168.110.77
GATEWAY=192.168.255.254
IPV6ADDR=2001:DB8::200C:417A/64
IPV6ADDR_SECONDARIES=::ffff:192.168.110.77/64
Configure the Database Listener
The next step is to configure the Listener for this IPv6 address.
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 2001:db8::200c:417a)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.110.77)(PORT = 1521))
)
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
)
)
)
Configuring the Client
The last step is to create an appropriate TNS entry for your application
AVI =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 2001:db8::200c:417a)(PORT = 1521))
)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = DB11g)
)
)
AVI2 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST =192.168.110.77)(PORT = 1521))
)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = DB11g)
)
)
Test the Connection
use the utility TNSPING
database-server :/u/app/oracle/v11.2.0/network/admin > tnsping AVI
database-server :/u/app/oracle/v11.2.0/network/admin > tnsping AVI2
Used parameter files:
Used TNSNAMES adapter to resolve the alias
Attempting to contact (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST =192.168.110.77)(PORT = 1521))) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = DB11g)))
OK (10 msec)
database-server :/u/app/oracle/v11.2.0/network/admin
in 11g UTL_INADDR.GET_HOST_ADDRESS gives me IPv6, while I need IPv4
in 11g UTL_INADDR.GET_HOST_ADDRESS gives me IPv6, while I need IPv4
SELECT UTL_INADDR.GET_HOST_ADDRESS FROM DUAL;
disable ipv6 on OS level
c:\Windows\System32\drivers\etc\hosts
SELECT UTL_INADDR.GET_HOST_ADDRESS FROM DUAL;
disable ipv6 on OS level
c:\Windows\System32\drivers\etc\hosts
---------------
ORA_CLIENT_IP_ADDRESS Returns the IP address of the client in a LOGON event, when the underlying protocol is TCP/IP

Symptoms:
Related To:
Error May Occur
Internal Error May Occur (ORA-600)
ORA-12839
ORA-600 [qerltcFetch_20]
Constraint Related
Parallel Query (PQO)
_disable_parallel_conventional_load
DML
Description
If you have a parent table and child table with a parent referential constraint
then running Parallel DML again this may fail with an unexpected ORA-12839
or even fail with an ORA-600.
Workaround
Setting "_disable_parallel_conventional_load" = true can help avoid this.
Please note: The above is a summary description only. Actual symptoms can vary. Matching to any symptoms here does not confirm that you are encountering this problem. For questions about this bug please consult Oracle Support.

Oracle 11g2 Database Replay
Oracle 11g2 Database Replay Features
Before system changes are made, such as hardware and software upgrades, extensive testing is usually performed in a test environment to validate the changes. However, despite the testing, the new system often experiences unexpected behavior when it enters production because the testing was not performed using a realistic workload. The inability to simulate a realistic workload during testing is one of the biggest challenges when validating system changes
Database Replay enables realistic testing of system changes by essentially re-creating the production workload environment on a test system. Using Database Replay, you can capture a workload on the production system and replay it on a test system with the exact timing, concurrency, and transaction characteristics of the original workload. This enables you to fully assess the impact of the change, including undesired results, new contention points, or plan regressions. Extensive analysis and reporting is provided to help identify any potential problems, such as new errors encountered and performance divergence.
Database Replay performs workload capture of external client workload at the database level and has negligible performance overhead. Capturing the production workload eliminates the need to develop simulation workloads or scripts, resulting in significant cost reduction and time savings. By using Database Replay, realistic testing of complex applications that previously took months using load simulation tools can now be completed in days. This enables you to rapidly test changes and adopt new technologies with a higher degree of confidence and at lower risk.
You can use Database Replay to test any significant system changes, including:
Database and operating system upgrades
Configuration changes, such as conversion of a database from a single instance to an Oracle Real Application Clusters (Oracle RAC) environment
Storage, network, and interconnect changes
Operating system and hardware migrations
You can use Database Replay to capture a workload on the production system and replay it on a test system with the exact timing, concurrency, and transaction characteristics of the original workload. This enables you to test the effects of a system change without affecting the production system.
Database Replay supports workload capture on a system running Oracle Database 10g Release 2 and newer releases. In order to capture a workload on a system running Oracle Database 10g Release 2, the database version can be 10.2.0.4 or higher. Workload replay is only supported on systems running Oracle Database 11g Release 1 and newer releases.
Before capturing a database workload, carefully consider the following options:
*Restarting the Database
–to avoid capture partial transaction
*Defining the Workload Filters
–inclusion filters or exclusion filters, not both
*Setting Up the Capture Directory
