How to fix Oracle SQL Developer connection issue "Got minus one from a read call"

 During connection from SQL Developer to EBS database got below error message:


Status : Failure -Test failed: IO Error: Got minus one from a read call



Following solution can be done :
1. Go to directory $ORACLE_HOME/network/admin
2. Modify sqlnet.ora file with following parameter: 
tcp.validnode_checking = no

3. If you don't want to disable this, you can put the machine names as follows:
tcp.invited_nodes=(machine1, machine2)

3. Bounce the listener.

Due to security enhancements it is not good to put tcp.validnode_checking = no or comment out will through error 
when we start listener like below:
Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=shsebs7idb1.appsolworld.com)(PORT=1522)))
TNS-00584: Valid node checking configuration error
 TNS-12560: TNS:protocol adapter error


Better plan is to add localhost or IP address of client  (Local Computer) in the sqlnet.ora file
That will solve the problem

NAMES.DIRECTORY_PATH=(TNSNAMES, ONAMES, HOSTNAME)
SQLNET.EXPIRE_TIME= 10
tcp.validnode_checking = yes
tcp.invited_nodes=(192.168.1.3,SHSEBS7IDB1.appsolworld.com)
SQLNET.INBOUND_CONNECT_TIMEOUT =60
SQLNET.ALLOWED_LOGON_VERSION_SERVER=8

How to troubleshoot Long Running Concurrent Request in EBS 12.2

 The following points need to answer before jumping into troubleshooting: Are there any recent code changes done in the concurrent program?           Check long_running_sid and verify the recent code change of last_ddl_timestamp after a             discussion with the developer. Was this running long in the last few run as well, or was this time only?            ==> Check the program history. How much time does it take to complete?           Once again program history can give us some idea. Are these jobs fetching higher data compared to the last run           ===> Confirm on data change . Query Plan change will indicate this issue. Does this job runs at any specific time or it can be run anytime           ===> The nature of the job can help to understand the job's nature. Does this job fetch data using DB Link          ====> Check whether the DB link is involved or not. The below-given approach would help to conclude the gray areas. Check the load of the server using t
