Question

Oracle instantclient_11_1: how to install and set environment variables in Windows XP?

Asked by: epifanio67

Hello Experts,

I have install Oracle 11g on centOS 5. Now,
I am installing Oracle instantclient_11_1 on a separate machine, winXP.
Here are the install procedures: (from Oracle docs):

2. Unzip the packages into a single directory such as "instantclient".

3. Set the library loading path in your environment to the directory in Step 2 ("instantclient"). On many UNIX platforms, LD_LIBRARY_PATH is the appropriate environment variable. On Windows, PATH should be used.

Question 1:
There is no .exe file, how do I run this program?

Question 2:

My PATH variables has the following values:
%SystemRoot%\system32;
%SystemRoot%;
%SystemRoot%\System32\Wbem;
C:\Program Files\Intel\WiFi\bin\;
C:\Program Files\QuickTime\QTSystem\

Do I just need to add ;C:\instantclient_11_1 to the current PATH variable?
is that it?

thx,

Edit the PATH environment setting and add c:\instantclient_11_1 before any other Oracle directories. For example, on Windows XP, follow Start -> Control Panel -> System -> Advanced -> Environment Variables and edit PATH in the System variables list.

Set desired Oracle globalization language environment variables such as NLS_LANG. If nothing is set, a default local environment will be assumed.

if you experience connection problems to remote Oracle instance a possible cause could be firewalls and antiviruses. Oracle Listener will redirect the initial port 1521, so to have opened 1521 will not be enough.

"Question 1:
There is no .exe file, how do I run this program?"

The client itself is just the libraries needed by OTHER programs so they can connect to Oracle db's.
If you have no other tools, or just want to have sqlplus, it needs to be downloaded separately and put into the client directory.

The sqlplus zip is on the same otn page as the rest of the instant client packages.

by: epifanio67Posted on 2009-08-05 at 07:21:11ID: 25023728

ok... thx u experts....

lemme try it...

by: epifanio67Posted on 2009-08-05 at 08:02:17ID: 25024216

ok... I set the variable and put the sqlplus files on the same dir.
I changed the directory name to
C:\instantclient

Now, I am not sure what to expect/do?
I have cmd open and I am on C:\instantclient
how do I test connectivity? execute sql commands? etc?

is there a GUI version to create DBs, run scripts, and manage them?

thx.

by: sdstuberPosted on 2009-08-05 at 08:08:56ID: 25024295

no GUI, remember the instant client itself is nothing but libraries to allow OTHER tools to connect.

OTHER tools would include sqlplus (a separate install) or for a GUI SQL Developer (another separate install) or 3rd party apps (also separate installs)

you will need to have your sqlnet.ora and tnsnames.ora set up,
or, using sql developer you can connect directly via host and port

by: sdstuberPosted on 2009-08-05 at 08:09:30ID: 25024301

you can find sql developer on otn here...

http://www.oracle.com/technology/software/products/sql/index.html

by: sdstuberPosted on 2009-08-05 at 08:10:50ID: 25024326

for your sqlnet and tnsnames setup, ask your dba for the information required.

by: epifanio67Posted on 2009-08-05 at 08:21:59ID: 25024487

thx so much...

I see... I need to create DBs and run a bunch scripts... do I do this via SQLPlus? or Do I need to install SQL Developer for Win? if I need to install SQL Developer for Win, what is SQLPlus and instant client used for?

thx

sorry for the basic questions... it took me 3 weeks to install Oracle 11g on Linux.... Now I am battling to connect to it...

thx

by: sdstuberPosted on 2009-08-05 at 08:29:18ID: 25024579

the client provides the libraries that OTHER tools like sqlplus and SQL Developer need in order to connect.

sqlplus is the standard command line tool for talking to oracle databases.

sql developer is a gui tool for doing development but it can help with administration too

easiest way to set up your connection...

create these directories
C:\instantclient_11_1\NETWORK
C:\instantclient_11_1\NETWORK\ADMIN

inside the admin directory create a file called tnsnames.ora

in that file put the attached snippet and fill in the "your" fields with the appropriate values
you can put the servername or the ip address for the host, I recommend using the name.

then save the file and from command line try this...

sqlplus yourusername/yourpassword@yourdbname

yourdbname=
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = yourdatabaseserver)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = yourdbname)
    )
  )

thx so much...

Now I understand what you mean by libraries that OTHER tools need...
sorry I am a bit slow..
:-)

ok... lemme try...

by: sdstuberPosted on 2009-08-05 at 08:42:37ID: 25024730

Note, the 1521 port is the default, but if your listener (on the linux server) is configured for a different port then change the value to match whatever your listener uses.

by: epifanio67Posted on 2009-08-05 at 09:42:44ID: 25025335

got it... still trying..
one meeting to attend to..

thx

by: epifanio67Posted on 2009-08-05 at 10:46:24ID: 25026062

ok, here is what I did...

I created the NETWORK dir and ADMIN under it.
then, I open notepad and created the tnsnames.ora (see code snippet below)

then,

I open cmd
accessed directory C:\instantclient (I removed _11_1)
then I typed the following command:
sqlplus SYSTEM@DEMO11.1
it asked me for pwd
I typed it and I get these errors

ORA-12154: TNS: protocol adapter error

asked me for username and pwd... tried again and I get SAME error... tried third time and get:

SP2-0157: unable to CONNECT to ORACLE after 3 attempts, exiting SQL*Plus

any ideas? thx

#tnsnames.ora
 
DEMO11.1 = 
 (DESCRIPTION = 
   (ADDRESS = (PROTOCOL=TCP)(HOST=111.111.1.1)(PORT=1521))
   (CONNECT_DATA = 
     (SERVER = DEDICATED)
     (SERVICE_NAME = DEMO11.1)
  )

ok, I am able to access the Enterprise Mgr on the machine running Oracle 11g.
I access it by launching firefox and typing this address:
https://localhost.localdomain:1158/em

do I have to be logged in to Enterprise Mgr at host to access it via instant client remotely?

I have SQLPlus and Oracle SQL Developer installed; but can't connect to database instance...

I keep getting an IO expection: The Network Adapter could not establish the connection.

I able to ping the host machine...

please help..

by: sdstuberPosted on 2009-08-05 at 13:22:14ID: 25027705

what is your ping output? from client machine to host machine

what is the content of your listener.ora on the host machine?

also there is another listener.ora
under ORACLE_HOME/network/admin/samples

is that the one you want to see?

by: sdstuberPosted on 2009-08-05 at 14:00:16ID: 25028040

I'm assuming you've obfuscated your values and those aren't literals.

the host ip and the ping ip should be the same
or, use the same localhost.localdomain

by: epifanio67Posted on 2009-08-05 at 14:15:52ID: 25028180

thx...

yeah.. I am still not sure if it is a big deal or not to provide IP addresses or not..

you mean change the listener.ora host from:
localhost.localdomain
to
192.168.x.x
?

if yes, do I have to do the same for tnsnames.ora?
thx

by: epifanio67Posted on 2009-08-05 at 15:06:45ID: 25028549

thx sdstuber...

well, I changed both the listener.ora and the tnsnames.ora from localhost.localdomain to IP address; but I get this error:

[oracle@localhost bin]$ ./emctl start dbconsole
OC4J Configuration issue. /opt/oracle/product/11.1.0/db_1/oc4j/j2ee/OC4J_DBConsole_localhost.localdomain_DEMO11.1 not found

by: epifanio67Posted on 2009-08-05 at 15:38:37ID: 25028720

I put everything back to localhost.localdomain...
everything is working again...
I confirmed localhost = pinging IP...

any other possible ideas?

thx

by: epifanio67Posted on 2009-08-05 at 15:48:39ID: 25028784

do I have to do anything on the server side to be able to connect to it remotely? not Oracle Enterprise Mgr; but the server where it resides?

or do I have to add any configuration settings at Oracle Enterprise Mgr to be able to connect?

thx,

by: sdstuberPosted on 2009-08-05 at 21:55:00ID: 25030217

OEM - no

server side - do you have a firewall blocking port 1521?

by: epifanio67Posted on 2009-08-06 at 07:53:08ID: 25034093

thx...

no firewall at all..
I disabled SELinux
