Networking And Gateways :: Switch Between Application Server And Exadata
May 1, 2011
I configure exadata + 2 switch between application server and and exadata. And we have problem to connect to switch and load balancing between Ethernet switch to exadata.
We might end up that is 'How about remove ethernet switch and directly connect to exadata?' I don't know which idea comes up with Ethernet gigabit switch between application server and exadata, exadata might be gigabit.
but from application server to ethernet switch is still 100M network, it is only fast in that load, other load is still 100m , it might useless. and about load balancing, exadata is RAC cluster node, exadata is doing load balancing, why we want another load balancing feature of ethernet switch?
Is it good idea to have dual switch between application server and exadata? exadata iti is what might be pro and con of this setting? exadata is handled by oracle support team, but dual switch is only cared by application operation team, so if something wrong with switch, nobody except operation team can manage .
One of my databases which is running on exadata x2-2 , has been restored to non-exadata machine in order to test few things. I had a sub-partition table in the exadata , compressed for query high. test machine (NOT EXADATA) , after uncompressing this subpartiton tables i am getting the following err message :
ORA-64307: hybrid columnar compression is not supported for tablespaces on this storage type I have executed the following commands : alter table crm.cm_ncd modify partition P01_CM_NCD nocompress; alter table crm.cm_ncd modify partition P02_CM_NCD nocompress; alter table crm.cm_ncd modify partition P03_CM_NCD nocompress;
[code]...
ERROR at line 1: ORA-12801: error signaled in parallel query server P005 ORA-64307: hybrid columnar compression is not supported for tablespaces on this storage type If all the partitions are uncompressed why i am getting this error message ?
My client get the error Ora-12514 when he tries to connect to the db.Well;
1) we restart the services: "OracleServiceOrcl" and listener but nothing changes 2) We restart the server and nothing changes 3) We checked the dump and he was done on March,26th. No db export yesterday. Is there any link with the clock change of this week-end (location of the server: France)? 4) The lsnrctl services listener command run successfully but it doesn't mention the instance ORCL.
I want to connect ORACLE-11gR2 that is on linux with an MS sql server. DO i need to use some third party drivers like easy soft ? Can i configure the database gateway without any third party drivers ?
Secondly if my oracle is on linux, can i configure the gateway on a seperate windows machine(that will connect to linux oracle and ms sql server) as i have found the gateway installation setup only for windows version.
I am having difficulty in making the 32 bit Oracle client connection to an existing 64 bit DB. The 64 bit SQL*Plus will connect just fine, but when trying to configure the 32 bit client I can never get a successful TEST of the connection. It always returns "No TNS Listener". I have tried several things, but may be way off base. To name a couple ...
1) Stopped the 64 bit listener so my 32 bit listener can use Port 1521 ... no success 2) Tried naming the 32 bit listener to LISTENER32 to not conflict with the original LISTENER name ... no success
If there is a documented way to make this work, I would surely like to be pointed to the "how to" of this item. I need this as a commercial application I have that connects to the DB requires the 32 bit client.
I am having 11.2.0.1.0 database with windows2k3 OS. For ORA-609 error i have started server side tracing by adding TRACE_LEVEL_SERVER=16,TRACE_LEVEL_DIRECOTRY=D:TRACE,and DIAG_ADR_ENABLED=off in sqlnet.ora file and i reload the listener.
Now i want to stop tracing so i have tried TRACE_LEVEL_SERVER=off but it wouldnot work. After that i remove TRACE_LEVEL_SERVER=16,TRACE_LEVEL_DIRECOTRY=D:TRACE from sqlnet.ora file and reload the listener but trace file generation is going on D:TRACE. stop server side tracing.
When i connect from client to server the client looks up for the host address and port number in tnsnames.ora and connect to it via listener.ora in server.Where does pga and sga come into picture here?
Also what is the role of sqlnet.ora in client?What will happen if i specify a different port for the instance in tnsnames.ora and listener.ora?
Currently we are loading data from oracle to sql server through oracle 11g gateway. during running scripts most of the queries takes a long time to complete. Because of this performance issue, we want to configure oracle golden gate to move data from oracle to sqlserver. whats the difference between oracle gateway & oracle golden gate? both are performing same functionality?
I have a JBOSS aplication server connect to database. When I tested on local, everything was ok. But when i test on real system , have a message "connection time out" on log file of app server while Oracle db still active. I viewed OEM, the system is executing the query :
"SELECT a.path songFilePath, a.BEAT beat from vp_song a, mst_my_album b "+ "where "+ "a.BEAT = b.BEAT "+ "and b.my_album_id IN "+ "(select my_album_id from (select my_album_id, ROW_NUMBER() OVER (order by my_album_id asc) "+ "R from mst_my_album where msisdn = ?) WHERE R BETWEEN ? and ?)";
I have client and database on same machine, when I will connect to the instance , it will use IPC, suppose If I will use connection string then which process will handle this request?
We are having oracle 9i as database and migrating to sql server 2008. Our oracle 9i database connects to another oracle databases and these databases are having different oracle version(9.2.0.8.0, 9.2.0.7.0,10.2.0.5.0,11.2.0.2.0,9.2.0.6.0,10.2.0.4.0,8.1.7.4.0 )
I do have two queries :
1) how to connect from Sql server 2008 R2 to different Oracle databases
2) How will other oracle databases connect to Sql server 2008 R2 database
I have recently installed Oracle Express 10g Server on my local PC. I can successfully connect to this while bypassing the TNSNAMES from SQLTools, I can't however connect to this from Forms 10g or while using SQLTools with TNSNAMES. How do I configure my TNS names to use this server?
I have one query related to database connection from server to client.I have one database in the server and I want to connect from client.I set the tnsnames in client system as follows.
1. How would I know whether I'm running Shared Server or Dedicated Server? 2. How to configure Shared Server? 3. How to configure Dedicated Server? 4. How Can I use both these connection types with one database?
I mean one session with dedicated and one with shared at the same time.
connecting two oracle database in two different server.I installed Oracle 10g XE in both system.Both system act as Server.I need to connect both server using database link concept.
how to use the tnsnames,ora and listener.ora file for connecting both system.
Connecting Oracle to SQL Server via database link.
I am trying to connect from Oracle 10G to a SQL Server database. I have looked at the manual and i will admit that i am finding the documentation quite difficult to follow. There seems to be several options to use but none of the documentation describe how each option works.
As an example, i have been given the following information on the database i need to connect to (i.e. the SQL Server database)
- Username - Password - Database Name [lets assume the database name is data_extract]
Note: In listener.ora, i only added the last SID_DESC entry. I then went on and created the database link as shown below
create database link sqlservdb using 'sqlserver.db';
When i try to access a table i get the following error
sqlplus> select * from TESTTABLE@sqlservdb; select * from TESTTABLE@sqlservdb * ERROR at line 1: ORA-28545: error diagnosed by Net8 when connecting to an agent Unable to retrieve text of NETWORK/NCR message 65535 ORA-02063: preceding 2 lines from ORASQLSERVER
A couple of things i am not sure of:
- Where do i specify the username and password to access the sql server from the oracle db to the sql server db
- Having read around on the internet, i can see some people refering to a DSN datasource. I am told that the information that i have is all i need. Is this correct or do i need something else?
- The sid i specified in inithsodbc.ora and tnsnames.ora is actually the sql server database. Is this correct?
I have 9i RDBMS Software and RHEL 4. I want to install a Oracle Names server. I install RDBMS.But Where I run netmgr and want to configure and start Oname server it says.
$ORACLE_HOME/bin/names file not exists.
How Can I configure OracleNames Server using Oracle 9i On Linux.
I was trying to connect to SQL server from Oracle using Oracle heterogeneous services (HS).But I found that I do not have HS installed on my system. It was mentioned in Oracle website that we need to run 'caths.sql' script under the path $ORACLE_HOME/rdbms/admin.
But I do not have any such folder(rdbms) in my $ORACLE_HOME.What does it mean? And how can I install HS alone on my system(Since I already have oracle)
I have ora-12520. I run Oracle 11g on Red Hat 4 64 bit. Actually I have RAC but one node is down and I work only with up one (connection string point directly to listener of running node). I run test with not too big loading. select count(*) from v$sessions gets ~ 200 in maximum loading, but after half minutes I get this error in my logs. Each time, lsnrctl services show that all is right. It shows one service with one handler. I see nothing in alert.log. This is very strange, I know, and I'm sure that this is an actual alert.log because, I see there other events in actual time. Most important: I have SESSION parameter set to 600 and PROCESSES set to 400 so this must be enougha...
We got a big problem that we have a db link to connect to sql server(big 5).
In original setting, there is no Chinese characters in the data. We simply grab the data from sql server and do not have any issue. But now we have data with Big5. When we import the data into our Oracle DB, which uses UTF8, all the text becomes "?
Changing character set in DB is not possible. We need to convert the text into unicode format, or allow oracle/sql server to convert it automatically.
I'm facing ORA-28500 error while configuring HSODBC to SQL Server.
Below is the complete information related to listener.ora, sqlnet.ora and tnsnames.ora files. Listener status is showing dg4msql instance successfully started.
I guess I'm facing some issue while creating DB link.

I installed Oracle 10g (10.1) in Windows Server 2003 and i am able to connect to oracle using using SQL net. But when I tried to connect this using SQL Net from Windows XP, I am getting ORA-12560: TNS:protocol adapter error. But when I tried to connect as SYSDBA user, I am able to login in SQL plus. But for a normal user, not able to log in.
We've been administering a multiple instance production dB server with 3 different versions of Oracle installed.Currently, each of Oracle version had corresponding listener.Oracle 9i had 2 instances, 10g 6 instances & 11g 2 instances also.how I can integrate this 3 listeners into 1.
