Google Music India - Music search made simpler

Google has launched its Indian music search which is the best music search i have come across the internet.All the other music search has either limited songs or songs that do not match the search criteria selected by users.Currently the Google music search is for hindi songs and the english version is yet to be released.

The tagline for this search is " Search for artists, albums or songs ".Currently the collections of hindi songs are their music partners in.com, saavn and saregama . The search displays a thumbnail of music poster with recent movie releases on the landing page.

The search powers bollywood songs , traditional songs , albums , song by various artists and the users can even search by the title of the song.Thumbs up to the Google music search where music search is made simpler.Lets hope the English version would be available soon

Query to display timestamp along with date component

As most of us are aware what a Sysdate Function performs , it does return a DATE value when you query the current system date . The Sysdate is a powerful function used very often when you want to consider the system date in various coding practices.If one wants the function to return a immediate next days date then just add a 1 to the sysdate as ( sysdate + 1 ) .This will return the immediate next day's date.

Usage : Select sysdate from dual ;

Coming to the Sql query to see the time stamp component , you need to convert the sysdate format into character specifying what format of date and time you want to see.

Solution : Select  to_char ( sysdate , ' DD-MON-YYYY HH24:MI:SS ' )  from  dual ;

The result would be similar to this :

The Sysdate includes the timestamp component also but while displaying it only shows the date component and when to convert that using to_char function you could see the time component also.

To exclude the time component from sysdate function ,

use - Trunc ( sysdate )
The above function truncates the time component and returns only date component .

Download Missing Windows .dll files immediately - Dlldump

This is most common error you often see that a single or multiple (.dll) files are missing or corrupt when you have installed the application software or any other software that you use.The error could also be your system supporting dll files corrupt.

DLL - stands for dynamic link library which plays a major part in windows operating system.I had installed one software ,which showed .dll was missing . So i did a small research and found a cool site which holds large collection of dll files , and that s DllDump.com

DllDump.com - search for the dll file and download it  immediately , the reason why am using dlldump is that it allows immediate download option for user rather than misleading users with download here ,download there which the other sites normally do.Link to the site is ( here )

screen shot of dlldump website :

Dll Dump.com snapshot

Example Error : The program can’t start because MSVCR71.dll is missing from your computer. Try reinstalling the program to fix this program
Solution : After download , whats next ? where do i place the downloaded dll files ?

- Look for folder named system32, its located at /WINDOWS/ folder or use a folder search option in windows .

- Place the file in system32 directory and then re-start your application , if not re-boot /re-start your computer.Hope this works.

Tip :

• For 32 bit Windows : use -  C://WINDOWS/system32
• For 64 bit Windows : use - C://WINDOWS/SysWOW64
  

If not , try registering the ( .dll ) file present in the system32 folder after the download ,

Registering Dll file :
Type the following on the Windows Command Prompt
<>   

regsvr32.exe   Your_Dll_file.dll

After that restart / reboot the application or system.

Just for your information on Unregistering the dll :
<> 

regsvr32.exe  /u  Your_Dll_file.dll

A small difference in usage of " if - else if - else " in pl/sql , vb , Unix

The underlying logic of all the programs are same , only there is slightly change in their syntax and usage.I had worked on VB 6  past so always in that mode whenever using the other languages like PL/SQL .As i was working on "if-then-else " for pl/sql and found that it was flashing the syntax error . There is a small difference of this usage in three languages .

The following are the differences of  IF-THEN-ELSE used in VB , PL/SQL and UNIX shell scripts :

1) VB :

if ( condition ) then
    some_statements
else if  ( condition )
    other_statements

else

    final_statements
end if


2) PL/SQL :

if ( condition ) then
    some_statements ;
elsif  ( condition )

    other_statements ;

else

    final_statements ;
end if ;

UNIX :

if ( condition ); then
    some_statements
eif  ( condition );
    other_statements

else

    final_statements

Creativity And Negativity go side by side

Creativity , as the name suggests is nothing but creating things that does not exists. Its something like giving a life to anything.Most animations are a product of creativity where an animal speaks to a bird or a snake takes to a  mongoose. This can sometime be related to dreaming .One powerful aspect of dreaming is to reach the extreme corners of the world or the places which you have not come across with the power of imagination.

On the other hand Negativity is something like opposing , or thinking the reverse always.The one common thought that describes Negativity is to question oneself like What if ? What if i don't ? . Here more often one think that we cannot achieve anything because of the fear of failure that strikes most of the minds.

There is a lot of possibility that both go hand in hand sometimes which always has a real time impact , take a real time consideration that strikes ones mind, say you got a creative thought of jumping from a flying plane which is too high and without even thinking negatively you take a fall from plane and end up crashing on land creatively.If you had got a negative thought at that time of falling ,then you would carry a parachute along and then you could land safely.

From above thoughts sometimes think negatively along with creativity and see how success could follow you . This is applicable to real life experiences also ,may it be in field of business , artwork or anything for that matter.The only mantra to think here is "Be Negeto-creative" and change the way of thinking

Query to Check the PL/SQL and Oracle Database Version

Lsnrctl : error loading shared libraries libnnzll.so

The main problem causing this error is that the SElinux on Rhel 5 is blocking the listener to start the Listener control services ( lsnrctl ) . I had encountered this problem when i was starting the database for Oracle E-Business suite applications.After doin a small research i could get  the solution to this particular problem.

Error : lsnrctl : error loading shared libraries : /directories/libnnzll.so : cannot restore segment prot after reloc : permission denied

Cause : The SElinux of redhat preventing the lsnrctl service to start

Solution : set the SElinux to Permissive and then start the lsnrctl service , this will solve the issue.

Steps : at Root , use the following commands

• getenforce 
• setenforce 0 
• getenforce 

Follow the above commands in sequence at once ,these commands change the SElinux mode to permissive . Hope this will solve the issue .

Optical Human Transmitter (OHT) version 1.0

A device which transports human to any desired destination by converting them into photons (light rays) using optical medium such as optical fiber.

A destination point is entered in Optical Human Transmitter where a strong beam of light scans human body and converts atoms into photons and these photons are transmitted through fiber optic links . at the destination end another machine reproduces the actual atoms by photons there by recreating them back to original form

This is one such creative idea i have come across . One say that imagination is the most powerful tool that can reach you any place at any time . Say that you imagine or dream about New York , you reach there in a matter of seconds and travel around those places . How is that possible ? its all about Imagination and its power to take you there .

XML Importer for OA Framework ( A Simple - Easy to Edit Batch File)

As i had mentioned in the previous post about the XML importer . The easy to use and Ready batch file is given below which can be downloaded and a small modification to that file is needed for it to be used. Once this batch file is edited to the page whichever you want to import and just a Double-Click will do the trick to import the (.xml) file to MDS of database. The placing of this batch file will be discussed below .

Usage and Placing of Batch File :

Steps ,

1) Download the import.bat Batch file from the link below -

            import.bat

2) Go to jdevbin of jdeveloper extension and look for oaext directory and place the downloaded batch file in bin directory of oaext

            ie -  jdevbin/oaext/bin/BATCH_FILE_DOWNLOADED

3) Edit the following and leave the rest as it is

           right click on import.bat file and click edit , change :

•    JDEV_BIN_HOME  to your jdev_bin_home
•    JDEV_USER_HOME  to your jdev_user_home
•    In DB_CONNECTION change host , port ( if applicable ) and SID
•    PAGE2UPLOAD path of the (.xml ) file to import 
•    APPS_PASSWD your password     

4) Save the import.bat file

5) Double_Click on batch file

and thats it , simple and cool batch script which can be reused just by changing the XML file.

Your XML file will be imported to the MDS of database and follow my post : (click)  to check whether the XML file is imported or not .

A note on all the $TOP directory of Oracle apps R12

The  $TOP is the top most directory or can be said as an important directory for all oracle apps R12 .In order to use these directories through "cd" command of linux,  we must the source the Environment variables .The two important Environment variables for a developer would be :

• [sid]_[HostName].env
• APPS[SID]_(HostName).env

Where are these two files located ?
- Its located at $APPL_TOP ie at  " d01/oracle/[SID]/apps/apps_st/appl  " .

How do you source the Environment variables ?
- sourcing is done by using a dot (.) followed by and then environment variable name

example : To source VIS_localhost.env :

           

.  VIS_localhost.env

Note : don't forget to leave a space between dot (.) and env file .

A list of $TOP directories and their paths :

1) $APPL_TOP  -  d01/oracle/[SID]/apps/apps_st/appl/

2) $JAVA_TOP -  d01/oracle/[SID]/apps/apps_st/comn/java/classes/

3) $(application_short_name)_TOP  -    d01/oracle/[SID]/apps/apps_st/appl/(application_short_name)/12.0.0

example : for application_short_name PER - ( human resource)

     $PER_TOP  -  d01/oracle/[SID]/apps/apps_st/appl/per/12.0.0

Last thing to mention is about , $ORACLE_HOME ,

4) $ORACLE_HOME  -  d01/oracle/[SID]/apps/tech_st/10.1.2

Note : SID and HostName varies from system to system 

A note on jdr_utils API s of OA Framework

Jdr_utils package is most important APIs commonly used in OA Framework customisation. The most import scripts used are as follows :

• JDR_UTILS.LISTDOCUMENTS
• JDR_UTILS.PRINTDOCUMENT
• JDR_UTILS.DELETEDOCUMENT

A note on each of this  is as follows ,

1) The script which lists all the MDS documents of specified directory currently imported into database :

DECLARE 
BEGIN 
    jdr_utils.listdocuments ( '/oracle/apps/per/selfservice.webui' , TRUE ) ;
END ;

2) The script to list the Personalizations or Extensions for a specific object :

DECLARE 
BEGIN
    jdr_utils.printdocument ( ' p_document => /oracle/apps/per/selfservice.webui/ somepagePG ') ;
END ;

3) The script to delete document or personalizations/extensions :

DECLARE 
BEGIN 
    jdr_utils.deletedocument ( ' p_document => /oracle/apps/per/selfservice.webui/ somepagePG ') ;
END ;

Checking the presence of ( . xml) file in MDS of Oracle (OA Framework)

Whenever there is a new page added or any customization done to Oracle apps applications we use XML importer to import the new custom XML page to MDS of database.The XML importer Batch script to import XML files into MDS is ( here )

Assuming that you have imported the XML file ,and when you run the application the most common error would be (see the screen Shot)

                                                        ( click the image to expand )

The first thing to check here is whether you have successfully imported the XML page or not.To check this :

Run : On Sql * Plus or SqlDeveloper ,

DECLARE
BEGIN
   jdr_utils.printdocument ( p_document => ' /oracle/apps/per/selfservice/appraisals/somePG' )
END ;

The parameter to p_document is your XML path you wish to check . Few of the jdr_utils package will be discussed in coming posts.

Command to print the Current Working Directory

Bounce Apache for Oracle R12 applications (Linux RHEL 5 )

Any changes made to R12 applications through Jdeveloper or professional interface such as forms interface has to be bounced . One easiest way to bounce apache is to use adapcctl script located at scripts directory of INSTANCE_TOP.

Root user and Applmgr user can run this script , for R12 the instance top directory  is located at /d01/oracle//inst/apps/_/ i.e  $INST_TOP

Bounce the Apache server :

Locate the scripts directory at $INST_TOP/admin/scripts

then ,
           

./adapcctl.sh  stopall

then,
           

./adapcctl.sh  startall

Note : Root user and Applmgr user can run this script

Enabling port 8000 or 80 on Linux

A very simple method to check whether the port is working or not is , type the following at console :

telnet your_ip port_number (which u want to check)

telnet  192.168.1.2  8000

if you are able to connect it or can see a blank screen means the port is "open".

if not then change the firewall settings , do the following :

• check the : vi  /etc/sysconfig/iptables 

      You should find  :
   
      -A RH-Firewall-1-INPUT -m state NEW -m tcp --dport 21 -j ACCEPT
      -A RH-Firewall-1-INPUT -m state NEW -m tcp --dport 22 -j ACCEPT

     See if there is --dport 80 or 8000 or anyport which you want to access , if not add the following entry to iptables changing the --dbport to whichever port you want to open.

         

-A RH-Firewall-1-INPUT -m state NEW -m tcp --dport 80 -j ACCEPT

 restart the iptables service by :            

service  iptables   restart

hope this works , !!!!!!!

 Note : Its not limited to port 80 or 8000 ,its applicable to any ports
