Query to Check the PL/SQL and Oracle Database Version

It becomes a necessity to sometimes check the version of Oracle database being used or to check the version of PL/SQL being used.To check which Oracle database you are working on and also to check which PL/SQL release , the query used :

          
  select  *  from  v$version ;  

This query can be tested on sql*Plus , SqlDeveloper or any other query executable tools.Along the above version details you could see the CORE version , TNS version and NLSRTL version

The Complete query result would look like this :

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 .
