mongoDB error : aborting after fassert() failure

What to do when facing errors on mongoDB “aborting after fassert() failure”

I like errors, in mongoDB this is the first error I faced and luckily many times. This error i faced during restoring name-space on local and restarting db system. I am still searching the exact root cause of this issue but i am able to resolve the current problem through below steps.

  • Remove all relevant namespace files from data-file route path..
  • Now repair mongo instance using mongod process.
    • mongod --repair ////////// execute command from bin folder path
  •  Then start server using mongd process, if started server successfully then ..
    • mongod  ////////// execute command from bin folder path
  • Restore last backups as normal process.
  • Now check database by connecting mongo shell.
Thanks for reading, 
Please comment your experience if you faced and also share knowledge if you have better steps to resolve...

How to encrypt and decrypt Table data in postgres

For encrypting and decrypting , we must use the bytea data type on the column which we implement. Bcoz bytea will use the pgcrypto method by default. However, you will need to create the pgcrypto extension to enable these functions as they are not pre-defined in PostgreSQL/PPAS. Example CREATE EXTENSION pgcrypto; CREATE TABLE userinfo (username varchar(20), password bytea); >>    Inserting the data in an encrypted format INSERT INTO userinfo VALUES(' suman ',encrypt('111222','password','aes')); select * from userinfo ; >>    Retrieving the data as decrypted format SELECT decrypt(password,decode('password','escape'::text),'aes'::text) FROM userinfo; Thanks for reading Plz dont forget to like Facebook Page.. https://www.facebook.com/pages/Sql-DBAcoin/523110684456757
