Operating Systems AIX SQLoader & SQLplus error ? Post 303007972 by rbatte1 on Friday 24th of November 2017 06:31:44 AM

The commands ping and tnsping do different tasks. The ping will target an IP address, be that a server, desktop, switch, security camera, fridge or whatever networked device. tnsping on the other hand will take the name and try to make a connection to the running Oracle SID. It will first have to determine which host the database is on and get the IP address, so in at least needs to be able to ping the server. It will then use the name you give it and try to open a conversation with the listener (typically on port 1521 or the server) and check if the SID is valid.

The contents of tnsnames.ora provides the translation between the name you use and the server & name that the listener will respond to. The name you use could be changed to another by tnsnames.ora and/or another by the listener on the target server to get to the actual Oracle instance. If you are unable to validate the connection with tnsping, you will not be able to connect, however in your case you can't even get tnsping to start.

These errors suggest that you have not set up the environment correctly on your desktop or client, and that would explain why it cannot connect too, because it will not know where to find the tnsnames.ora file.

You should (at the least) have entries in your $PATH that included where executables are. Do you have a colleague that this works for that we can compare?

It would be good to see the output for both you & your colleague for:-
Code:
uname -a
ps
echo $PATH
echo $ORACLE_HOME
echo $ORACLE_SID
find / -name tnsnames.ora -o -name oraenv 2>/dev/null

You might also try
Code:
/u01/app/oracle/product/11.2.0/client_1/bin/tnsping database-name

to see the tool start, but I would not expect it to find tnsnames.ora so it will probably not connect. You might like to post the output in the thread too.


Please post all output/errors in CODE tags to make it easier to read and to preserve the spacing/indenting.



Thanks, in advance,
Robin

learn(1)						      General Commands Manual							  learn(1)

NAME
learn - Provides computer-aided instruction for the C shell SYNOPSIS
learn [-directory] [subject] [lesson] The learn command provides computer-aided instruction courses and practice in the use of Tru64 UNIX. OPTIONS
Allows you to exercise a script in a nonstandard place. DESCRIPTION
To get started, enter learn; if this is the first time that you are invoking the learn command, you are guided through a series of ques- tions to determine what type of instruction you want to receive. If you have used learn before and left your last session without completing a subject, the program uses information in $HOME/.learnrc to start you up in the same place you left off. To bypass questions, enter a subject or lesson. In order to enter a lesson, you must know the lesson number that you received in a previ- ous learn command session. If you do not know the lesson number, enter the lesson number as a subject. The learn command searches for the first lesson containing the subject you specified. If the lesson is a - (dash), learn prompts for each lesson; this is useful for debug- ging. You can specify the following subjects: files editor vi morefiles macros eqn C SUBCOMMANDS
There are a few special commands. The bye command terminates a learn session, and the where command tells you of your progress (where m tells you more.) The again command redisplays the text of the lesson and again lesson lets you review lesson. The hint command prints the last part of the lesson script used to evaluate a response, while hint m prints the entire lesson script. This is useful for debugging lessons and might possibly give you an idea about what is expected. EXAMPLES
To take the online lesson about files, enter: learn files You are then prompted for further input. FILES
Playpen directories. Start-up information. SEE ALSO
Commands: csh(1), ex(1) learn(1)
