Howto configure Timeout for database link

Hi,
how can I configure the expected timeout for a db link connection?
My problem is, that I've to get data from a far distance database and the network connection is not very good.
Sometimes it works pretty good, but often I get a not reachable error. Monitoring the server with ping shows, that the server is always alive, but the roundtrip time is high ( >200 ms).
System: Oracle 9.2.0.5
Linux (RedHat)
Thanks for help
Stephan

Well since db links just use the underlying SQL*Net configuration, what you're actually looking for is timeout settings for SQL*Net, there are two:
In the listener.ora file on the server:
INBOUND_CONNECT_TIMEOUT_<listener_name> = n seconds
Determines the limit the database listener will wait for a client connection to complete after the connection is made.
In the sqlnet.ora file on the server:
SQLNET.EXPIRE_TIME = n minutes
Determines the limit for the frequency of active connection verification of a client connection.
If the problem is you're getting disconnected because of network timeouts, it could be here or something in your LAN network settings.

1. If you have not previously executed JDeveloper, Run JDeveloper once
and exit.
This creates the initial JDeveloper.ini
2. Create links to JDeveloper's key files.
<blockquote>Right click on the Windows Start menu
Select Explore All Users to launch an Explorer window
We will refer to this as Explorer Window #2 because it has 2 panes
(left &; right)

thus adding folders here is the same as adding menu items to the Start
menu decedents, Adding folders here is the same as adding sub-menus!
In the right hand pane of Explorer Window #2, double click on Programs.
Double click on the Oracle JDeveloper Folder.
Select menu File | New / Folder to create a new folder.
Name the folder, Customize
Right click on the JDeveloper icon (either one)

Using generic format for database links in ODI Procedures

Hi,
As in procedure we use
create table <%=odiRef.getSchemaName("Target Schema","D")%>.TABLE2 as
select * from <%=odiRef.getSchemaName("Staging Schema","D")%>.TABLE1
where Staging Database and Target Database are logical schemas which will associate to respective physical schema while execution so the above statement will become as
create table Target_Schema.TABLE2 as
select * from staging_Schema.TABLE1
I just wanted to know if there is any way by which i can apply samethings for Database Links also.
Like if i have statements
create table TABLE2@Target_Database as
select * from TABLE1@staging_Database
can i replace DB links like Target_Database and Staging_Database?
Help would be appreciated. :)
Thanks,
Mahesh

I am not entirely sure about the exact requirement.
Any way ..
1.
create 2 variable .
v_get_src_schema : select '<%=odiRef.getSchemaName("<your_src_logical_schema>","D")%>' from dual
v_get_tgt_schema : select '<%=odiRef.getSchemaName("<your_tgt_logical_schema>","D")%>' from dual
2.
2 more variable to get the required DBLink
v_SRC_DB_LINK: select DB_LINK from all_db_links where owner='#PRJ_CODE.v_get_src_schema'
v_TGT_DB_LINK: select DB_LINK from all_db_links where owner='#PRJ_CODE.v_get_tgt_schema'
3.
create a procedure :
prc_create_table :
create table <%=odiRef.getSchemaName("Target Schema","D")%>.TABLE2@'#PRJ_CODE.v_TGT_DB_LINK' as
select * from <%=odiRef.getSchemaName("Staging Schema","D")%>.TABLE1@'#PRJ_CODE.v_SRC_DB_LINK'
4.
Create a package :
Connect all the steps in serial with OK line.
Execute and let us know what is the out come .
Thanks,

Error: The number of configured copies for database 'DB-1' (1) is less than the required redundancy count (2).

Hello , I think the below event alert 4113 is very common and is due to that only one database copy is present in DAG but is there any way we can stop this alert for the
specific database.
The message tells that there is only one copy of the database - create another copy and the warning message will go away but
we do not want to create another copy. So is there any way we can stop this event getting generated.
Database redundancy health check failed.

That regex looks odd to me. I assume you have databases with names like "Mailbox Database <ten digit number>" (standard Exchange default name, in other words), "ABC-DB" and "HOME-DB". If this is the case, wouldn't
you want "(?:Mailbox Database \d{10}$|^ABC-DB$|^HOME-DB$)"? THis works if I run it from a prompt:
[PS] C:\Scripts>"Mailbox Database 0123456789" -match "(?:Mailbox Database \d{10}$|^ABC-DB$|^HOME-DB$)"
True
[PS] C:\Scripts>"Mailbox Database 123456789" -match "(?:Mailbox Database \d{10}$|^ABC-DB$|^HOME-DB$)"
False
[PS] C:\Scripts>"Mailbox Database 12345678910" -match "(?:Mailbox Database \d{10}$|^ABC-DB$|^HOME-DB$)"
False
[PS] C:\Scripts>"HOME-DB" -match "(?:Mailbox Database \d{10}$|^ABC-DB$|^HOME-DB$)"
True
[PS] C:\Scripts>"ABC-DB" -match "(?:Mailbox Database \d{10}$|^ABC-DB$|^HOME-DB$)"
True
[PS] C:\Scripts>"ABCD-DB" -match "(?:Mailbox Database \d{10}$|^ABC-DB$|^HOME-DB$)"
False
[PS] C:\Scripts>"HOM-DB" -match "(?:Mailbox Database \d{10}$|^ABC-DB$|^HOME-DB$)"
False
I find it's easiest to test RegEx's from the prompt this way. If the above isn't your goal, let us know, and we'll see if we can come up with something better.

Hardware configuration recommendations for database and VM work

I'm looking for advice on system configuration for a computer to use at work for database, VM, and number-crunching applications. The database work will involve complex SQL queries against MySQL databases in the 5–50 GB range. I'll be using the computer for a variety of projects, and I'd like to configure and run Linux VMs on a per-project basis. The number-crunching will involve engineering applications, most of which will likely run in Linux. The database tables might be accessed from OS X or a Linux VM; I'm not sure at this point.
Advice or recommended reading on internal RAID, SAS, Fibre Channel, and the like would be appreciated. Would it make sense to have a large SATA boot drive that stores the VM and a second high-throughput drive array for the database tables? If so, what are some good options for configuring the latter? Staying in the $5k–$7k range would be nice.
Thanks,
Andreas

FileMaker is the best option if you want a good GUI front end. It's not free like MySQL but the price is worth it.

Configuring EM for database

Hi,
I have upgraded a 9.2.0.5 database to a 10.2.0.1 home. The upgrade was successfull. I also changed the listener port number since there was a default listener running on 1521. The new listener is now a namd listener on a different port. I now want to configure the EM agent so that I could use the web browser to keep track of the database.
I'm using emca as per the instructions given in after upgrading the database. But everything I have tried come back with the help menu displayed and I do not know how to proceed. Any help would be greatly appreciated.
I also tried the emctl but I get the message EM configuration issues: hostname_SID directory does not exist. I checked to see and the directory was never created.
How should I configure the EM?
Thanks,
Mamata

Hi,
emca command has changed its syntax for Release 2 and now a lot options.
emca -config dbcontrol db -repos create is the basic command , it creates some directories, populates configuration files with informations of your machine and the database you want to monitor, at the end it creates the repository owner (SYSMAN) and all necessary objects. If you create (not update) a new 10g database, normally this command is executed as one of the last steps by DBCA (if you chose you want to use dbconsole).

RegardsThere is about emailing that is specific to backups. It is simply an OS utility. Google 'sendmail' and 'mailx'. Have your backup job (or any other job) create a log file, then use the OS mail utility to email that log file.

Configuring timeouts for ReportService

Hello,
We are calling reports over the ReportService from Oracle Agile PLM for Process. We are receiving timeouts in PLM for Process. We have extended the period that PLM for Process waits for the completed reports, so we do not believe that to be the issue. Is there a timeout period for the ReportService?
Thanks,
Drew

Creation of Database link and access the same plus Snapshot creation

i want talk between two oracle server. i decided to go for snapshot creation with periodical refresh. For which i am having two oracle server's with different ip address located inside our office setup.
I have created a database link between two servers.
first server name global
userid scott
password tiger
second server name asil
userid scott
password tiger
both the user have been given dba rights.
in both the server the services and listners are all started. i gave the following command to create database link.
from asil server
create public database link global connect by scott identified by tiger using 'global'
the command was successful and the link was created. Now i tried to access a table of the scott user of the global server.
select * from emp@global;
now it is giving error. I want to know how the link can be created and how it can be accessed. i refered the 8i online documentation and done the things based on that. i expect valuble solution from all possible persons
null

A reason for this problem could be that your database is configured that a database link has to have exactly the same name like the global name of the database instance it should connect to.
Can you please provide the oracle error code / message ? With this information there might be more hints I can give you.

Configuring RMAN for dataguard.

Hi all,
Here we have a dataguard environment with db1(db_unique_name) as primary and db2(db_unique_name) as physical standby database. For both primary and secondary the ORACLE_SID is 'oracledb'.We configured dataguard in 10g environments and we are not using grid control. And now we want to configure rman for incremental backups. We are using a third catalog database to which we registered from primary db successfully. During primary rman configuration it is showing conflicts. Even the changes made in primary RMAN configuration are applied on to the standby too which i think shouldn't happen in this scenario. How to resolve this issue? Is this happening because of the same ORACLE_SID for both primary and secondary? I'm attaching the link of the doc that we followed also the errors and configuration in rman. Can anyone help?

Using database links in a plsql page process

I am trying to use a database link in a pl/sql page process.
It works fine when I use the link name in the plsql like this:
BEGIN
SELECT
CARD_ID
into
:P12_HDR_CARD_NUMBER
from     [email protected];
But the link name will be coming from a page item (P12_DBLINK) populated as follows:
select db_link d, db_link r from user_db_links;
I have tried the following and it's not working:
DECLARE
l_link VARCHAR2(30);
BEGIN
l_link := :P12_DBLINK;
SELECT
CARD_ID
into
:P12_HDR_CARD_NUMBER
from     fusion.EXM_CC_COMPANY_ACCOUNTS@l_link;
this gives me:
ORA-04052: error occurred when looking up remote object FUSION.EXM_CC_COMPANY_ACCOUNTS@L_LINK.WORLD ORA-00604: error occurred at recursive SQL level 3 ORA-02019: connection description for remote database not found
I thought that maybe the link name was getting appended with .WORLD automatically but the link name already has .WORLD at the end. I tried stripping that off first but the error is the same.
Is there some synatx for this that will work for this? Will I need to use dynamic sql?
Any suggestions are most appreciated.
thanks,
john

Hi John,
check the following example to use the execute immediate statement for your purpose

let me know if this answers your query in the current thread

Why dbms_metadata.get_ddl can not work for db link?

db: 10.2.4
os: RH linux 5
our problem is that we can not get ddl from dbms_metadata.get_ddl for database link, however the db link does exist here as below.

SQL> select dbms_metadata.get_ddl('DB_LINK','XXRPTH_OPDBC.XXR.COM','XXR') from dual;
ERROR:

appreciate for any guides
thanks

I ran into this in a slightly different form, I can't remember all the rules and details, but to work around it I had to specify a fake name appendage in the db link creation in order to keep it from automatically appending the global domain.
Something like
create database link abcdef.remotealias connect to ... using 'remotealias'
rather than
create database link abcdef connect to... using 'remotealias'
At least I think it was fake, I was flopping around trying things until I got it to work, and I wound up making it the same as the tnsnames alias. I think I decided I didn't have to, but left it as the lesser of two confusions, and was miffed that the creation scripts I had been using for years suddenly had to be fixed. Yeah, it was my own damned fault, but I still think the way this works is crazy. Now hopefully someone will explain this simply so I look foolish.

OSB: Business Service Timeout for JCA Connection

Hi,
I am wondering if there's any way to configure timeout for a JCA connection in OSB? It's not configurable in Business Service.
Thanks.

Hi Anuj,
I am using DbAdapter. As for operation, which operation are you referring to? Where do I check to verify this?
Thanks.

Database link - Oracle 9i

I'm trying to create a table 't1' on to a different database db2, (full access) from db3 DB pulling the data (select statement) from db1 database .
Steps followed as;
1) Logged in as connect string: sc1/sc1@db3
2) create [email protected]
as select * from [email protected]
Can I achieve what Im looking for... Please share your ideas

your ideasYou should be able to do this. However, you must make sure that there are database links created on db3 for db1 and db2. Also, the user for db1 database link (call him db1user) must have select rights on table t2 and the user for database link db2 (call him db2user) must have create table rights on db2.
I don't have multiple database available at home so can't give you exact sample. However, the general solution is along the lines mentioned below.
- Create a database link for db1 while logged into db3.
"create database link db1link connect to db1user identified by passwd using db1serviceName;" where db1user is the user on db1, passwd is the user's password and db1serviceName is the tnsnames service name for db1 (check tnsnames.ora on db3 machine).
- Same way, create a database link for db2 while logged into db3.
"create database link db2link connect to db2user identified by passwd using db2serviceName;"
- Now, create the actual table.
"create table t1@db2link as select * from t2@db1link"
Hope that helps. Let me know if that worked for you.

Timeout for connect

Hi there!
I've got troubles how I can define a timeout for CreateConnect methods.
I made a search, and found that OCCI itself doesn't support such timeout.
I tried some parameters in sqlnet.ora
such as: names.initial_retry_timeout, SQLNET.INBOUND_CONNECT_TIMEOUT and names.connect_timeout=3, but that didnt help at all.
Does anybody know, how I can set timeout for database connect?
Thanks,
Amdras

Hello Cipa,
I have set this variable, but when connecting via sqlplus this process is using 100%CPU and I am not able to connect to database to start it.
When starting sqlplus with strace it seems that there is loop in the poll function. Do you have any idea what the problem might be? Oracle version is 10.2.0.1.0
Thanks for any help.
Martin
