Configuring the listener and other issues

I installed 2 instances of database on the same database and the same house database.
Instances use the same listener. If I try to start the business manager in the browser for both instances,
Enterprise Manager starts just to the last installed instance. I edited the listener.ora one file
Add a Description more with another port number as follows:

(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP) (HOST = merge)(PORT = 1522))
)



for the following content:

LISTENER_APPDB =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP) (HOST = merge)(PORT = 1521))
(ADDRESS = (PROTOCOL = CIP)(KEY = EXTPROC1521))
)
)

now the file looks similar to the following:


LISTENER_APPDB =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP) (HOST = merge)(PORT = 1521))
(ADDRESS = (PROTOCOL = CIP)(KEY = EXTPROC1521))
)
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP) (HOST = merge)(PORT = 1522))
)
)

ADR_BASE_LISTENER_APPDB = D:\app\oracle2

SID_LIST_LISTENER_APPDB =
(SID_LIST =
(SID_DESC =
(SID_NAME = CLRExtProc)
(ORACLE_HOME = D:\app\oracle2\product\11.2.0\dbhome_1)
(= Extproc PROGRAM)
(ENVS = "EXTPROC_DLLS=ONLY:D:\app\oracle2\product\11.2.0\dbhome_1\bin\oraclr11.dll")
)
)

I also changed the port of one of the instances in the file tnsnames.ora from 1521 to 1522.
It is now possible to launch Enterprise Manager in both cases. But after I connect to one of the
bodies with Enterprise Manager from the logs of the other instance. Is it ok then? Will I have problems
with this configuration? Should I do something different?

Second question: if I installed an instance during installation, some patches where
automatically installed. After that, I installed another instance. Do I have to patch this body too?
Are the hotfixes installed for the DBMS together or just for a single instance?

* Third question: if I have 2 case how can I set the parameter btree_bitmap_plans for only *.
one of the instances? I found the following code to do this:

ALTER SYSTEM SET "_b_tree_bitmap_plans" = false SCOPE = SPFILE;

but for which the instance parameter will be defined for both or just one? What I have to choose
one of the instances? How can I do?

Set oracle_sid = your_db_name

then, in SQL, use command below

ALTER SYSTEM SET "_b_tree_bitmap_plans" = false SCOPE = SPFILE;

Do you have any recommendations for the Support of Oracle to use?

  • Configuring the listener and Instance registration

    Hello

    I was watching one of the cases that we run on a box and I could not understand how the connections are deployed for this particular case, and I hope someone can enlighten us please...

    We run Solaris 5.10 with two houses of installed oracle 10.2.0.4 and 11.1.0.7, a running instance that:

    Oracle: oracle/home / > ps - ef | grep smon

    Oracle 28299 28048 0 08:31:23 pts/7 0:00 grep smon

    24870 2965 Oracle 0 Jul 17?          ora_smon_dbs 45: 03

    TNS_ADMIN to point to ""/var/opt/oracle ": "

    Oracle: oracle/home / > echo $TNS_ADMIN

    / var/opt/oracle

    I had a look at the directory and there is no file tnsnames.ora:

    Oracle: / var/opt/oracle > ls-l

    Total 7

    -rw - r - r - 1 oracle dba 474 14 April 2014 listener.ora

    -rw - r - r - 1 oracle dba 55 7 March 2014 oraInst.loc

    -rw-rw-r - 1 oracle dba 750 19 Jan 10:33 oratab


    We then looked at the configuration of the listener.ora file, and the SID_NAME does not reference a real SID:


    listener.ora # Network Configuration file: /var/opt/oracle/listener.ora

    # Generated by Oracle configuration tools.

    SID_LIST_LISTENER =

    (SID_LIST =

    (SID_DESC =

    (SID_NAME = PLSExtProc)

    (ORACLE_HOME = appl/oracle/10.2.0)

    (= Extproc PROGRAM)

    )

    )

    LISTENER =

    (DESCRIPTION_LIST =

    (DESCRIPTION =

    (ADDRESS = (PROTOCOL = TCP)(HOST = dbmzsbsdb01.int.un) (PORT = 1521))

    (ADDRESS = (PROTOCOL = CIP)(KEY = EXTPROC0))

    )

    )


    For awhile, I thought it's ok that we could fix local_listener of the database, but once again if this is the case then I expect to see a file tnsnames.ora with address or list of addresses of listeners specified them then obviously this was not the case and certainly enough, looking at the database local_listener was not established:


    SYS@dbs> show parameter local_list


NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
local_listener                       string

    I also noticed that we use the listener 10g instead of the 11 g listener, and looking at the processes running, it is certainly the case:


    Oracle: / var/opt/oracle > ps - ef | grep tns

    9384 2965 Oracle 0 Jun 27?          80:37 /appl/oracle/10.2.0/bin/tnslsnr EARPHONE-inherit

    Oracle 2777 26227 0 08:15:50 pts/7 0:00 grep tns


    I'm a little lost on how this database is same! ??? any ideas on what's happening please?


    Thank you


    WebLogic even will need connection strings and you should be able to find them.

    The JDBC thin driver does not use tnsnames.ora and fat jdbc driver can use tnsnames.ora but is not necessary.

    JDBC uses the :: syntax.

    The database registers itself with the listener using the service_name parameter in init or - better - spfileSID.ora

    All this is documented, so not too difficult to find for you,

  • How to configure the listener with SSL

    Hi Experts,

    I use 11g R2 EE. I want to configure my database listener so that it can be connected using SSL.

    Can someone provide me guide step by step to configure the listener with SSL (including the portfolio so that comes in the image).

    The command line configurations will be well appreciated.

    Thanks in advance

    Alexander gelin

    The client configuration is the same as the server:

    1. create the portfolio.

    2 creating CSR and copy it in CA.

    3. the CSR signal with your certificate root.

    4 copy signed CRT file and root of public certificate to the client.

    5 configure the sqlnet.ora clients.

    Heavy customers already contains the necessary files. For thin clients, it is necessary to install the full or instant client.

    In SQLDeveloper, connection string should be like:

    jdbc:oracle:oci:@(DESCRIPTION= (ADDRESS_LIST= (ADDRESS= (PROTOCOL=TCPS)(HOST=)(PORT=))) (CONNECT_DATA= (SERVICE_NAME=)) (SECURITY= (MY_WALLET_DIRECTORY=D:\Oracle\client.test.p12)))

  • Manually configure the listener apex via command line

    I would like to be able to configure the listener apex via the command line.
    Is there an api or method to achieve this?

    Is it possible to take an apex-config. XML as a template and make changes to this environment and place it in the config.dir directory
    According to me, placing a! in front of the clear text password cryptera apex listener reboot?

    Is the method of model above a taken way in charge of the configuration of the apex listener script languages?

    I set the value of config.dir for /apex_lsnr
    This will search the apex - config.xml in the directory above or it will search the XML in /apex_lsnr/apex?

    +/apex_lsnr + would be option 1 - who doesn'work currently.

    ++ refers to the 'context' you have deployed your APEX listener, so if you used the default value (apex) this would actually
    +/apex_lsnr/apex +.

    -Online cp apex - config.xml $DOMAIN_HOME/apex_lsnr/apex

    Note that APEX auditor records the location of the apex - config.xml, he uses actually started. If it comes to the temporary location (default), he found nothing in your configured directory.

    Hi Sue,

    It is not a fluke, it certainly works that way.
    Just a few final remarks:
    -He didn't need to change/copy content of + / orabackup_iris2/apex_listener/export/home + to + / orabackup_iris2/export/apex_listener + in your case, as the first directory does not seem to be a temporary.
    -I recommend you put the java call, including parameters in a shell script and call instead.
    - nohup works very well for the background to the application process. As you probably know he does not offer a service 'system' - like functionality.
    - nohup creates a default file for the release of the console in employment has begun. I would recommend to redirect to a file named, then all the outputs.
    So your final configuration would look as follows
    start_apex_listener.sh

    #!/bin/sh
java -Dapex.port=8080 -Dapex.home=/orabackup_iris2/export/apex_listener -Dapex.images=/orabackup_iris2/export/apex/images -jar /orabackup_iris2/export/apex_listener/apex.war

    appeal of nohup

    nohup /orabackup_iris2/export/apex_listener/start_apex_listener.sh >> /orabackup_iris2/export/apex_listener/apex_listener.log 2>&1 &

  • Question about the listener and the process server in dedicated server mode

    Hello

    The Oracle documentation says that, when a client connection request is received on the server, the receiver creates a process server who will work with the database instance to perform the tasks requested by the user/client process. So far, everything was good.

    Now, when the user is on the Oracle himself server, the listener didn't need to run to establish a connection to the database. Therefore, it is possible to stop the Listener and not always connect using sqlplus and a valid username and password.

    In the case above, the question is: if the listener does not work, what/who created the process server that communicates with the instance of the database on behalf of the user? In other words, in the normal case, the listener could get the request and create the server process. When the listener does not work what part of the Oracle Gets the requests and creates the server process?

    Clarification on how this case is handled are very much appreciated, thank you,

    John.

    John,

    I guess that you have asked the same thing in a different form in another thread. In the case, when the process of the user and the server is to be on the same side, the communication done by using the Protocol bequeth and the user, since it is not not going to use a (@) sign, he would use a default service for connected sys$ users .

    Thank you for taking the time to read this. I would like to know the "best practices" for unplugging my computer permanently to the internet and other updates. I thought I would do a clean install of Windows XP, install my Microsoft Works again and nothing else. I would like to effectively transforming my computer into a word processor. He continues more and more slow. I get blue screen errors, once again. I received excellent Microsoft Support when it happened before, but since my computer is around 13 years, I think it is not worth the headache to try to remedy. I ran the Windows 7 Upgrade Advisor, and my computer would not be able to upgrade. Please, can someone tell me how to make it only a word processor without updates or internet connection? (I already have a new computer with Microsoft Windows 7 Home Premium, it's the computer that I use. The old computer is just sitting there and once a week or so I updates.)

  • Why some items in 'Open an existing project' have just the name of the project and others have access to the entire file path?

    I have SP1 2012 LabVIEW and on the main screne of LabVIEW selecrt "show projects".

    Why some elements of 'Existing Open' (project) have just the name of the project and others have access to the entire file path?

    Examples of two lines in the list of projects.

    Ping.lvproj (with a path: C:\Users\mlevine\Documents\MPCE EQT\EQT Software\Ping.lvproj)

    C:\Users\mlevine\Documents\Common package Mission trainer (CMPT) \SUW Surface Warfare\Weapon permission Panel (WAP) \WAP LabVIEW Software\WAP fire authorization server 28 April 2015

    No chance, it's because I made a copy of this software and stored on a network drive power off and it went out of this network drive?

    So if LabVIEW sees two or more versions of the same software, he decides to use the name to differentiate between full path?

    I'd still rather it shows just the name of the project and if you hover over the name it shows the full path.

    Thank you

    Mark

    If you have opened a project of the same name from a different location, it is when it shows the full path both - in this case showing just the name of the project would not help because it would be the same thing!
