DemoIdentity.jks file not found

Dear DBA-Mates, Topic: demoidentity.jks does not exist for Nodemanager

Hope you all are doing Good in Covid-19. Stay safe, be safe!!!

This post is related to Node Manager Issue which throwing error while starting as DemoIdentity.jks is not found under below path.

.../wlserver_12.2.1/oracle_common/common/nodemanager/security/DemoIdentity.jks

When we start Node Manager, it will not start and will come out of nohup. So, we need to check the log file where we can see this alert.

Error/Action:

ora-data.blogspot.com$ ls -ltr .../wlserver_12.2.1/oracle_common/common/nodemanager/security/DemoIdentity.jks

ls: cannot access .../wlserver_12.2.1/oracle_common/common/nodemanager/security/DemoIdentity.jks: No such file or directory

As above we can see file is not found.

So, we can create it manually without any issue.

1. We need to set the wls env file as shown below:

ora-data.blogspot.com$ pwd

.../wlserver/server/bin

ora-data.blogspot.com$

ora-data.blogspot.com$ . setWLSEnv.sh

2. Once above env setted. Go to security directory where you want to create that DemoIdentity.jks file.

How to get sql query output in xml format from putty session

Dear DBA-Mates, How to get sql query output in xml format.

Hope you all are doing well and Safe at Home!!!

We would like to share one of very important and useful query for How to get SQL Query output in xml/xls readable format.

This is very headache if you are running in Putty Session.

Even we also use this same format for such queries. So, we thought to share to you all and it will be easy for us also for references in future.

This type of request will be send by the developer or functional team which they may need for some analysis or monthly reports generation.

Whatever if they asked then as a DBA we need to provide them, even though angry inside Hahahah.

And the worst things those queries will be running 2 to 3 hrs and rows may be 2 to 3 lakhs, so can imagine it.

$sqlplus / as sysdba

SQL> SET LINESIZE 10000

SQL> SET VERIFY OFF

SQL> SET FEEDBACK OFF

SQL> SET PAGESIZE 999

SQL> SET MARKUP HTML ON ENTMAP ON SPOOL ON PREFORMAT OFF

SQL> SPOOL <Output_Filename>.xls

SQL> set time on   ## To Capture query start and end time

SQL> @<Filename>.sql

SQL> spool off;

Optional:

SQL>SET MARKUP HTML OFF ENTMAP OFF SPOOL OFF PREFORMAT ON

SQL>SET LINESIZE 2000 VERIFY ON FEEDBACK ON

OR

SQL> set feed off markup html on spool on

SQL> SET PAGESIZE 50000

SQL> SPOOL <output_filename>.xls

SQL> <your_query like select * from dual;>

SQL> SPOOL OFF;

OR

SQL> set pagesize 50000

SQL> set heading on

SQL> set echo off

SQL> set colsep ','

SQL> set heading on

SQL> SET LINESIZE 999 VERIFY OFF FEEDBACK OFF

SQL> SET MARKUP HTML ON ENTMAP ON SPOOL ON PREFORMAT OFF

SQL> spool workflow.xls

SQL> <Your query>

SQL> Spool off;

OR

Save Query output as HTML file from SQLPLUS

As alternative you may use below block of code from the sqlplus only to save the output as HTML file.

SQL> set linesize 4000

SQL> set verify off

SQL> set feedback off

SQL> set pagesize 9999

SQL> set markup html on entmap on spool on preformat off

Happy New Year

Dear Friends, Happy New Year 2020 to All!!!

Today we would like to share some experiences which may useful for life time for everyone.

Just want to say Happy New Year with some words which may useful.

I don’t want to just celebrate New Year on 1^st Jan and then same day all like earlier days.

So, here would like to share some real life time achievements which will be like golden year for next coming life.

If you want to be a success or real person in real life then we can try these below points which may help us to be a beautiful person.

And if you are a beautiful or true person from inside then success will come automatically.

So, promise you guys to yourself only that you will try to follow it and make some changes in yourself this year.

1. Take a steps which you want to do. 

Means do whatever you want if that does not impact anyone in bad ways.

BUT one advice before starting be careful and take a full proof plan and be mentally prepared for facing either failure or success.

2. Find out the best things and apply in yourself.

Example: Means note down only 4 to 5 points which can make a good person and follow them like be true, be kind etc…

3. Speak less but effective. People says that “jo jitna kam bolta hai , utna achha hota hai” .

4. Always do your best in present day, off course next day will be your best.

But see, all days can’t be best but almost days can be yours best.

5. Try to minimize you mistakes.

Friends, we are human and we do the mistakes that’s not a problem but we should learn from it and try to avoid from next time.

Note down your Only One weakness in One month and then work on that and come over that.

Again write next weakness and do the same, like this you can be a perfect person in Next year (1 yr).

You can’t imagine what you can achieved like this.

So, this is the thing which I though may useful you all here, and also I am sure I will also follow it from this Years. Because No body is perfect … We all are in same boat only the difference is some boat is deep water some boat at the sore.

So, Guys Wish you all a very very Happy New Year 2020 !!! Enjoy like king but with good heart…
