2) GUN ZIP the file:-
—————————–

gzip file_name

Note:- While trying to download gunzip file from server to local machine it should be done in binary mode. Then it can exact using the wipzip software in WINDOWS Operating System.

After gzip, if we want to unzip the file then use the following.

gunzip file_name

2.1) To unzip or gunzip the file :-
———————————————

gunzip file_name

Example:-

gunzip XYZ_1.0_5.tar.gz

2.2) To untar the file:-
——————————

tar -xvf file_name

Example:-

tar -xvf XYZ_1.0_5.tar

3) To run the strings for the spawand program:-
————————————————————-

strings -a (shell_script_file_name) > (logfile.log)

Example:-

strings -a GLPURGE > /home/partners-home/hex/preddy/phani1.log

3.1) Basic grep command:-
———————————–

Example:-

grep ‘DROP index’ adwork001.log > /home/partners-home/xyz/preddy/dropindex.txt

Note:- grep command is just like the search for some specfic word in your windows file.
In Windows Operating System, we use the (CTRL+F) and then we give the word we want to search. Similarly, grep is used for UNIX or LINUX Operating system. In the above Example, I am searching for the ‘DROP index’ Word in adwork001.log file. And I want all the finding of this search stored in some file. So, I have given the path and file name where it should save.

4) Specfic to some project:-
————————————-

To check the number lst files:-
—————————————–
Example:-

ls -altr *.lst | wc -l

Note:- If some folder have some specfic extension files, then we can count the number of that specfic extension files then we can use the above command. In the above example, I am searching for the ‘lst’ extension files count.

To check the number of sql files with hit files :-
————————————————————

grep ‘.sql’ *.lst | wc -l

Note:- Say, we have some .sql files names in all the lst files in some folder. Then we can use the grep command to count the sql file names.

To check the number of files with hits in the lst file:-
——————————————————————

grep ‘Number of files with hits : [1-9]’ *.lst

Note:- You can also give the count of the files with the range. In the above example, I have givne the range from 1 to 9. If it find any number from this range then, it will get in the count.

To create the file of the complete module :-
——————————————————–

grep ‘.sql’ *.lst > lst_sql_’module_name’.txt

Example:-

grep ‘.sql’ *.lst > lst_sql_gl.txt

Note:- The above example to do the search and to the search results in some given file name.

5) To find the file in the current folder and subfolder:-
———————————————————————

find . -name ‘file_name*.sql’ -print

Example:-

find -i . -name ‘poXWFUNT*.sql’ -print

Note:- POXWFUNT.sql is the file name which I want to search. ‘i’ in the above command indicates that, search should not be based on case sensitive.

6) To grep the file for a specific word:-
————————————————-

grep -i ‘WORD’ FILE_NAME > log_file_name

Example:-

grep -i ‘ALTER table’ adwork001.log > altertable.txt

7) To Know the PORT number of Env file:-
—————————————————–

setenv | grep PORT

Note:- Run the above command after login to Instance. And you have would have the read privileges for the file. This is mostly useful for people, who are working in the Oracle Application. 

7.1) For specfic session we can change the variable value:-
————————————————————————-

setenv variable_name variable_value

Example :- The following was the current value.

INSTANCE_ENVID=XYZ12

(Used the following command to check the value (setenv | grep OBT)).

setenv OBTADMIN_ENVID OBT_12

The above command has changed the value of the variable.
———————————————————————

OBTADMIN_ENVID=OBT_12

Note:- If you exit from the session and then variable value will be revert back.

8) To know the path of the log and out files of the application:-
——————————————————————————

>>cd $APPLCSF

There you will have the log and out folders.

You can also try the following command to know the value of the APPLCSF variable.

env | grep log

9) Turn-on the application server:-
———————————————-

./oraWebAndForms.sh start Instance name

Example:-

./oraWebAndForms.sh start XYZ12

Note:-
——
1) XYZ12 is the Instane name.
2) After turnning the Database and concurrent manager up. still the application front end will not open. The you need to run the above script from the applmgr user

To login to different user:-
——————————

sudo su – applmgr

Note:- applmgr is the superuser name. This username can depends on the DBA, what they have given at your Instance.

9.1) If you are getting 500 Internal error message after bounce back then try this:-
—————————————————————————————————–

Try to restart your application and restart your manage and see if it resolve the issue.

For the 12 Release, the above solution may not work. After you cleared _pages in R12, you’ll need to recompile because the default mode is ‘justrun’ instead of ‘recompile’ as was in 11i.

I did the following while applmgr in my Instance XYZ12 env and the login now works:

1. cd $FND_TOP/patch/115/bin
2. ./ojspCompile.pl –compile –flush -p 2

(You can check if you are able to open the application or not). If you are still facing the issue then try rebounce the application and see if it resolve the issue).

3. /home/applmgr/oraWebAndForms.sh bounce xyz12

(./oraWebAndForms.sh bounce zyx12)

Note:-
——
You need to run the above script in the applmgr user

sudo su – applmgr

10) To start or stop the Internal concurrent manager:-
———————————————————————

cd $ADMIN_SCRIPTS_HOME/

./adcmctl.sh start apps/apps

./adcmctl.sh stop apps/apps

Note:- This need to be run from applmgr user
—–

sudo su – applmgr

11) To stop the database or start the database:-
————————————————————

cd $ORACLE_HOME/appsutil/scripts/xyz12_server/

Note:- The above path is specfic to my server Instance.

To stop the database:- adstopdb.sql*

To start the database:- adstrtdb.sql*

Note:- This need to be run from Oracle user.
——

sudo su – oracle

12) Converting all the tabs to space in the file:-
———————————————————–

By setting the following options in your ~/.vimrc file,
when you use tabs, spaces are actually entered into the file,
although it “feels” like there are tabs because backspaces work as they would with tabs.

You’ll never have to worry about differing tabstop standards again.
Try it out, I promise you’ll be completely sold!

set softtabstop=4
set expandtab
set shiftwidth=4

Note also that if you want to convert a file with tabs to all spaces, set the above options and then use:

:retab!

13) To know the Operating system on server (unix):-
——————————————————————

>uname

Example:-
———–

2007.08.06-3:18:03 preddy@oscar[6]/home/partners-home/xyz/phani/xyz_23Jul/abc/la/utils > uname

HP-UX

14) To know the Operating system on server from database:-
—————————————————————————

begin
dbms_output.put_line(‘Port String: ‘||dbms_utility.port_string);
end;

15) Admin utility to compile all the invalid objects:-
—————————————————————–

i) This utility is avilable for the applmgr user. Use the following command to login with applmgr user.

>>sudo su – applmgr

ii) Choose the Intance and then use the following command to run the adadmin utility.

>>adadmin

{ Note:- It will ask for the $APPL_TOP path. If the default path is not the correct one then provide the correct path.
It will ask for the Log file name. (Default name willl be (adadmin.log)).
It will ask if you can be notified by email if a failure occurs. (Default will be set for NO).
It will ask for the Batchsize (Default is 1000).
It will ask for the correct database name.
It will ask to enter the password for your ‘SYSTEM’ ORACLE schema.(“manager” will be the password).
(manager password will be only one you enter manually. Rest of things you take the default values.)
It will ask to enter the ORACLE password of Application Object Library (default will be [APPS]).
}

iii) To will give the menu with different options.
—————————————————–

We will choose the “Compile/Reload Applications Database Entities menu” option. It will be 3 option normally.

iv) To will again give the other set of menu optins.
———————————————–

We will choose “Compile APPS schema” option to compile all the Invalid objects in APPS schema.

(Note:- You can also use $ORACLE_HOME/rdbms/admin/utlrp.sql (which will compile all invalid objects thru SVRMGRL.)).

17) To know apps password:-
————————————–

cd $ORACLE_HOME/reports60/server

more CGIcmd.dat

You will find userid=APPS/apps_pass@Instance_name

Note:- If you have the FTP access for server files. Then we can know the Apps password.

18) QUOTA:-

——————

echo $variable_value

The value of the environment variable can get from the echo command.

Example:-

echo $APPL_TOP

In the above command we get the APPL_TOP variable value set in the environment file. APPL_TOP is the environment variable in the environment file.
