manual Upgrade from 10gR2 to 11gR1

Pre-Requisite:

You should have enough MEMORY, server space and SWAP SPACE on Oracle database 10g, which you want to migrate.

Also here we are upgrading 10g to Oracle Database 11g – Beta 6 (11.1.0.6)

Step 1) Installing Oracle 11g Home

We cannot upgrade the existing Oracle Home, since 11g is not a patchset. We have to install 11g oracle home as a separate ORACLE_HOME in parallel to 10g Oracle Home.

Step 2) Pre-Upgrade Utility

In 11g Home you installed, go to $ORACLE_HOME/rdbms/admin and copy the file utlu111i.sql to some temp location.

$  cp   utlu111i.sql   /tmp

For more about utlu111i.sql :

 http://oracleflash.com/38/Oracle-11g-Release-1-Pre-Upgrade-tool-utlu111i-sql.html

Step 3) Executing the recommended steps

Following are the critical steps to be executed based on above warnings. These commands are to be executed while connecting to database from 10g Oracle Home

WARNING: –> Database is using an old timezone file version.
…. Patch the 10.2.0.1.0 database to timezone file version 4
…. BEFORE upgrading the database. Re-run utlu111i.sql after
…. patching the database to record the new timezone file version.

Finding the Version of existing timezone files:

SQL> select version from v$timezone_file;

          

          version

          ------------

                   2  

here oracle 10.2.0.1 has timezone file version of 2

Before you upgrade your timezone file version, you must run utltzuv2.sql to see if there is data that will be affected by the timezone file version upgrade. The script utltzuv2.sql creates a table named sys.sys_tzuv2_temptab, and fills it with data that may get affected by the timezone file version.

SQL >  select * from sys.sys_tzuv2_temptab ;

           no rows selected

here we see no rows but if we see any rows then we need to take that data backup and restore after timezone file version upgrade

Step 4) Run Pre-Upgrade Utility again

Run utlrp.sql to validate the objects if there is any invalidate objects.

SQL> @?/rdbms/admin/utlrp.sql

Check for any INVALID Objects in the database before upgrade starts:

SQL> select count(*),object_type,owner from dba_objects  where status = ‘INVALID’ group by object_type,owner;

SQL> purge DBA_RECYCLEBIN

Gather dictionary stats to run UPGRADE process fast,

SQL> exec dbms_stats.gather_dictionary_stats;

Create pfile from spfile 

Shutdown  à shut down the database in oracle 10g.

Copy the pfile of database from ORACLE_HOME/dbs(10g) to ORACLE_HOME/dbs(11g) using cp command.

In that make changes shown below,

 1.     Remove BDUMP, CDUMP, UDUMP and their locations

 2.     Add Diagnostic_dest=/’$ORACLE_BASE/diag’-àlocation for diagnostic dest

 3.     Change audit_file_dest location

 4.     Change compatibility to 11g and save it.

After executing the recommended steps, run the pre-upgrade utility once again to make sure, you don’t get any critical warnings. If everything looks fine, shut down the database from 10g Oracle Home.

Step 5) Starting Upgrade

Source the following variables for 11g Oracle Home

[oracle@/opt/oracle/11.1.0/db_1/dbs]$ export ORACLE_HOME=/opt/oracle/11.1.0/db_1[oracle@/opt/oracle/11.1.0/db_1/dbs]$  export PATH=$ORACLE_HOME/bin:$PATH[oracle@/opt/oracle/11.1.0/db_1/dbs]$  export ORACLE_SID=orcl[oracle@/opt/oracle/11.1.0/db_1/dbs]$ export TNS_ADMIN=$ORACLE_HOME/network/admin

connected to the database sys as sysdba

sqlplus “/ as sysdba” –> will be connected to idle instance

SQL> startup upgrade

SQL> SPOOL upgrade.log
SQL> @$ORACLE_HOME/rdbms/admin/catupgrd.sql

Once the upgrade finishes, It will shut down the database automatically.

Now export New oracle HOME and startup the database

[oracle@/opt/oracle/11.1.0/db_1/dbs]$ export ORACLE_HOME=/opt/oracle/11.1.0/db_1

[oracle@/opt/oracle/11.1.0/db_1/dbs]$ export PATH=$ORACLE_HOME/bin:$PATH

[oracle@/opt/oracle/11.1.0/db_1/dbs]$  export ORACLE_SID=orcl

[oracle@/opt/oracle/11.1.0/db_1/dbs]$  export TNS_ADMIN=$ORACLE_HOME/network/admin

Login again as sysdba and startup in normal mode.

Check the dba_registry for the components and its status

SQL> startup 

SQL> select substr(comp_id,1,10) comp_id, substr(comp_name,1,25) comp_name, substr(version,1,10) version, status from dba_registry order by modified;

All the components should be VALID state

Step 6) Post-Upgrade Steps

Once the upgrade completes, restart the instance to reinitialize the system parameters for normal operation.

SQL> STARTUP

Run utlu111s.sql to display/verify the results of the upgrade:

SQL> @?/rdbms/admin/utlu111s.sql

Run catuppst.sql, located in the ORACLE_HOME/rdbms/admin directory, to perform upgrade actions that do not require the database to be in UPGRADE mode:

SQL> @?/rdbms/admin/catuppst.sql

Run utlrp.sql to recompile invalid objects after upgrade

SQL> @?/rdbms/admin/utlrp.sql

SQL> select count(*),object_type,owner from dba_objects  where status = ‘INVALID’ group by object_type,owner;

Run utluiobj.sql after the upgrade to identify any new invalid objects

Edit /etc/oratab file with new 11g Oracle home and comment out 10g oracle home

How to share your Android WiFi connection over Bluetooth

What can you do if you want to get your laptop online but you only seem to be able to pick up a wifi signal on your phone? What about if you want to get multiple devices online, but only want to pay to connect one? There is a solution - you can share your phone's WiFi connection to more phones, tablets and computers using Bluetooth so other devices can get online. Here's our guide on how to share your Android phone's WiFi connection over Bluetooth.

If you don’t have access to a wireless internet connection, it's easy to share your phone's data connection to other devices so you can get them online. But it's a slightly different story if you're looking to share a single internet connection between multiple devices.

Share WiFi over Bluetooth

Get your phone online using a WiFi connection and you're then ready to configure the connection for sharing over Bluetooth. It's a great way to get multiple devices online if you happen to be in a coffee shop or other location that issues codes for getting connected to the internet and you want to keep the costs down. Sharing a wireless signal via Bluetooth is also a good option if you are having trouble getting a particular phone or computer connected to the network in the usual way.

To share your phone's wireless connection, start by enabling Bluetooth. 

Once you are connected, head straight to Settings and move to the Connections section. Under the Network connections heading, click More networks and then tap Tethering and portable hotspot.

Bluetooth tethering is a simple way to share your phone's internet connection. 

Enable the Bluetooth tethering option by ticking the box. You'll see a warning that Bluetooth visibility needs to be adjusted.

Before other devices can connect to your phone, you need to make sure it's visible. 

Open up Settings, make sure that Bluetooth is enabled, and then tap the Bluetooth link in the Connections section. Tick the box next to the name of your phone to make it visible to other devices.

Enable Bluetooth on another device and you can connect to the internet via your phone. 

With this done, you can then use the Bluetooth capabilities of your laptop, tablet or other device to connect to your phone and make use of its internet connection. To connect a Windows computer, open Devices and Printers in the Control Panel, right click the icon representing your phone and select Connect using > Access point and you're ready to start browsing the internet.
