Custom Message Setup on PeopleSoft Signon Page

Whenever a maintenance activity is scheduled, we use to publish message in the sign on page to intimate the users rather than sending mails. I remember every time an activity is scheduled, the login page HTML file (signin.html) residing in web server needs to be edited, which requires a minimal knowledge of HTML scripting. Moreover web server bounce is required to get the changes reflected in front end.

Guys using People tools 8.51 and later don’t need to worry about this, as there is a new feature with tools release 8.51 onwards where we have an option to configure display message via PIA itself and it does not require any code changes. In a single stretch you can create list of messages and you can set the time frame to display that specific message. 

Navigate to People Tools > Utilities > Administration > Shutdown Msg (PT 8.53),


Click on the plus button to create new message and View/Edit hyper link to edit the existing message. 


Once you click the plus button, you will find a space to post your message and also you can find an option to specify when and how long the message should be displayed. 

I have replicated this post @ http://www.citagus.com/citagus/blog/custom-message-setup-on-peoplesoft-signon-page/

Oracle Upgrade from Oracle10g to Oracle11g


Below are the steps to Upgrade the Oracle database from 10.2.0.3.0 to 11.2.0.1.0:

Step 1) Installing Oracle 11g Home:

Install 11g database as a separate ORACLE_HOME in parallel to 10g Oracle Home.

Example my 10g Oracle Home is: D:\oracle10g\product\10.2.0\db_1, then my 11g Oracle Home is: E:\oracle\product\11.2.0\ db_1

Step 2) Pre-Upgrade Utility:

In 11g Home you installed, go to $ORACLE_HOME\rdbms\admin and copy the file 'utlu112i.sql' to some temp location (C:\temp).

Then login to the 10g oracle database AS SYSDBA and run 'utlu112i.sql' you copied to temp folder.

--This script provides information about databases to be upgraded to 11.2.

Step 3) Finding the Version of existing time zone files:

SQL> select * from v$timezone_file;

SQL> SELECT CASE COUNT (DISTINCT(tzname))
WHEN 183 then 1
WHEN 355 then 1
WHEN 347 then 1
WHEN 377 then 2
WHEN 186 then case COUNT (tzname) WHEN 636 then 2 WHEN 626 then 3 ELSE 0 end
WHEN 185 then 3
WHEN 386 then 3
WHEN 387 then case COUNT (tzname) WHEN 1438 then 3 ELSE 0 end
WHEN 391 then case COUNT(tzname) WHEN 1457 then 4 ELSE 0 end
WHEN 392 then case COUNT(tzname) WHEN 1458 then 4 ELSE 0 end
WHEN 188 then case COUNT(tzname) WHEN 637 then 4 ELSE 0 end
WHEN 189 then case COUNT(tzname) WHEN 638 then 4 ELSE 0 end
ELSE 0 end VERSION
FROM v$timezone_names;


If the output is 4, then it is well and good and it requires no additional steps.

If the output of this is < 4 then prior to upgrade we need to apply the Timezone patch.

SQL> select banner from v$version;


It gives DB version and accordingly you have to find the patch at Metalink. Download the zipped patch and unzip it in temp folder (C:\temp).

Step 4) Applying Timezone patch:

Copy the files from location: C:\temp\patch_file\files\oracore\zoneinfo and paste it to existing Oracle 10g location “D:\oracle10g\oracore\zoneinfo”. Make sure to keep backup of existing folder so that you could revert if any problem occurs.

Bounce the database and check the TIMEZONE version again. Again run the 'utlu112i.sql' and by now, the timezone file version should be upgraded.

Step 5) Gather Dictionary stats:

You may have found some warning messages in the output of 'utlu112i.sql' execution. Please do execute the below scripts to avoid those warnings.

Connect as SYS user,

SQL> EXEC DBMS_STATS.GATHER_DICTIONARY_STATS;

SQL> EXEC DBMS_STATS.GATHER_SCHEMA_STATS ('SYS');

SQL> EXEC DBMS_STATS.GATHER_SCHEMA_STATS (‘SYSMAN’);  (if OEM in use)

After executing the above recommended steps, run the pre-upgrade utility 'utlu112i.sql' once again to make sure, you don’t get any critical warnings.

Step 6) Starting Upgrade:

Copy the PFILE from 10g home to 11g home. In the copied PFILE, change the COMAPATIBLE parameter from '10.2.0.3' to '11.2.0.1'.

Delete the old listener service (10g) & create a new one using ORADIM utility.

Set the environment variables as in the below example.

SET ORACLE_HOME=C:\oracle11g\product\11.2.0\dbhome_1
SET PATH=C:\oracle11g\product\11.2.0\dbhome_1\bin:$PATH
SET TNS_ADMIN=C:\oracle11g\product\11.2.0\dbhome_1\NETWORK\ADMIN
SET ORACLE_SID=FIN89COP

Connect as SYS user,

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

SQL> startup upgrade;

ORA-32004: obsolete and/or deprecated parameter(s) specified
ORACLE instance started.

Then run the Catalog Upgrade ‘catupgrd.sql’ located in $ORACLE_HOME\RDBMS\admin.

SQL> @catupgrd.sql

--This script is to be used for upgrading a 9.2, 10.1 or 10.2 database to the new release.  This script provides a direct upgrade path from these releases to the new Oracle release.

Once the upgrades finishes, it will shut down the database automatically.

Step 7) Post-Upgrade Steps:

Login again as SYS and start the database in normal mode. 

SQL> STARTUP;

Check the dba_registry for the components and its status.

SQL> select comp_name,version, status from dba_registry;


Run utlu111s.sql to display 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

Check if there are any invalid objects in the upgraded database.

SQL> select count (*) from dba_objects where status = ‘INVALID’;

If the invalid objects exist, run utlrp.sql to recompile.

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

SQL> select count (*) from dba_objects where status = ‘INVALID’;

This completes the upgrade.

Now the Pfile would be in 10g format. Shutdown the database, change the Pfile structure to 11g and bring it up.

ORA-12170: TNS:Connect timeout occurred

When I tried to connect to my database via SQLPLUS, I was getting the error "ORA-12170: TNS:Connect timeout occurred".  I understood that the error could be due to firewall issue or database down or listener down or bad sqlnet.ora parm or even because of network issue. I did check on everything and found the firewall block caused the issue in my Windows server 2008 R2. Now I have to turn off the firewall that blocks the database port.


How to Turn off Firewall for DB Port:

Navigate to Control Panel --> All Control Panel Items --> Windows Firewall, click on Turn Windows Firewall on or off option and check the status of Firewall. If it is On, turn it Off and try connecting to database.



If it works, then the problem is due to firewall blockage. Now turn it On and go back to Windows Firewall page. Click on Advance settings option; create a new rule as shown in the snapshot below.


Follow the below screenshots to know the options to be followed while creating the rule to unblock DB Port. 


Specify the DB port you have given while setting up the DB.



Whatever name and description give here will be reflected in the Inbound Rules page.

 


 

Now try connecting to the database. It worked for me and I hope this will help you as well. If you have any doubts, please feel free to comment on it.


If you find the error is because of slow network or system, then reconfigure one or all of the parameters SQLNET.INBOUND_CONNECT_TIMEOUT,SQLNET.SEND_TIMEOUT,  SQLNET.RECV_TIMEOUT in sqlnet.ora to larger values. If a malicious client is suspected, use the address in sqlnet.log to identify the source and restrict access.  Also verify that your hosts file has a DNS entry. Eg: 102.54.94.97    

In Windows, the hosts file is located at win/system32/driver/etc/ and on UNIX, Linux, it is located in /etc/hosts
