SC3.2 oracle listener times out

I have an issue where at random times, solaris cluster is restarting one groups listener resource. I can see in the log that the monitor is timing out after 180 seconds. After 3 times that the monitor probe times out, it cycles the listener. Can someone please explain what the monitor does or what it's trying to do that doesn't succeed after 180 seconds? Can I run the monitor by hand for testing purposes, or will that confuse the cluster?
Also, when the monitor fails 3 times, and it tries to cycle the listener,the stop process is also failing. Does the stop process simply run "lsnrctl stop" for the SID in question, or are their additional steps performed for the shutdown?

Thanks Tim, I figured that is what the probe would do, I just didn't see it. I'm not sure I fully understand the monitor and monitor_check scripts. Does the monitor_check call on the monitor script based off the parameters provided? Is this interaction documented so I can RTFM instead, all info on the scripts I found on docs was very brief but maybe I need to keep looking. I currently have the resource unmonitored until we can figure out the issue with the delay, I understand I can simply run lsnrctl commands to test things, but I was hoping to simulate as close as possible what the cluster is doing if at all possible.
Can I simply run the below script and get stats back on this:
/opt/SUNWscor/oracle_listener/bin/oracle_listener_monitor_check -R reportprdls -T SUNW.oracle_listener -G reportprd

Wait on TCP errors w/o time out (error 62) on VxWorks

Hi,
I have a service request running with this one but I wondered if you could try to reproduce the issue as NI has so far been unable to reproduce it. I have attached the sample code. I have made a screencapture but that seems too large to upload. I will try to get the size down.
When trying to open a tcp listener on a port which an external application is already trying to connect to while the software is starting up this will result in an error 62 when waiting on the listener. The wait is not going to wait the defined timeout. Surprisingly though even though the listen vi seems to get bypassed without waiting it will pick up a connection if the external application tries to connect and will accept the data without fault.
This is a problem with potentially catastrophic result as the correct behaviour of the application relies on the mercy of the sender not trying to connect while the software is starting up.
I have tested the behaviour on a sb-rio 9605 and a crio 9074 (example attached)
I have tried on LV2012 and 2013 with August and February drivers.
Steps To Reproduce :
Please look at attached examples. Adjust the the ip address of your target both in the project and in the client vi. First run the server vi and then start the client vi. The interesting output can be seen on the server front panel. You will see expected behaviour in that the iteration counter goes up when the listener times out or gets a connection. The transmission indicator goes up when a connection is established. Now stop the server by pressing the stop button and relaunch it. This way the client is already running and trying to open connections while the software starts up. You will see the iteration counter erratically go up and the transmission indicator go up when ever the client tries to connect.
Source of problem:
I have now pinned the problem down to the "create listener". It seems that a "corrupted" listener gets created when the network buffer is not empty. The listener gets created without error and works when there is an inbound connection but shows the erroneous behaviour when nothing is coming in. The problem can get worked around by closing and re-opening the listener in case of an error 62.
looking forward to your feedback
best regards
Mathis

Need help in setting connection time out in Oracle 9i

My firewall is causing problems in that it is causing me to have timeout problems when tyring to start my Oracle 9i database.
The best solution is to reset my connect_timeout taht is to be found in listener.ora. But this has been replaced by initial_retry_timeout (I think) for Oracle 9i.
initial_retry_timeout is to be found in sqlnet.ora in
C:\oracle\ora90\networkADMIN\SAMPLE
it is set to 30
#name.initial_retry_timeout = 30
There is another sqlnet.ora file in C:\oracle\ora90\network\ADMIN all these contains is:
# SQLNET.ORA Network Configuration File: C:\oracle\ora90\network\admin\sqlnet.ora
# Generated by Oracle configuration tools.
SQLNET.AUTHENTICATION_SERVICES= (NTS)
NAMES.DIRECTORY_PATH= (TNSNAMES, ONAMES, HOSTNAME)
I added the following line to this file restarted my PC but time out still took 30 secs.
I dont have much experience of databases apart from writing sql and store procedures.
So I have no idea apart from pure guess work in trying to sort thsi problem out.
Thanks for any help.
Tony
names.initial_retry_timeout = 5

You do not indicate whether you are using the Oracle Names server. The names.initial_retry_timeout tells Oracle Net how long to wait, in seconds, for a response from an Oracle Names server before it attempts the next in your preferred list. You indicated, however, that you were having a problem with your firewall. The only connection this setting has with a firewall is that the firewall may be causing the connection to the Oracle Names server to timeout. If that is your problem, then adjust the value of this parameter to increase or decrease the delay before Oracle Net attempts the next server in your preferred list. If, on the other hand, your problem is in connecting to a database, then this parameter will have no effect.
What I do not understand is how your firewall can cause problems with starting your database. Is this a software firewall running on your PC? If so, what program is it? You should be able to setup a rule in the firewall software to permit the connection.
Kind Regards,
Russ Cannon

JDBC connection to Oracle 10g RAC periodically times out

I've been banging my head against the wall for months now and can't figure out why this is and what's causing it.
We have 6x CF8 servers in our environment. 3 of which work perfectly and the other 3 have the following problem. All 6 machines were installed at the same time and followed the exact same installation plan.
When I configure Oracle RAC data source, some of the machines time-out connecting to Oracle from time-to-time.
Config:
Solaris 9 on both CF and Oracle
CF8 Enterprise with the latest updater.
Apache 2 (not that it's relevant)
6 machines, load-balanced (not clustered), identical install and configuration.
data source config:
JDBC URL: jdbc:macromedia:oracle://10.0.0.3:1521;serviceName=dbname.ourdomain.com;AlternateServers= (10.0.0.4:1521);LoadBalancing=true
DRIVER CLASS: macromedia.jdbc.MacromediaDriver
The problem:
Every few minutes, CF starts hanging requests that deal with a specific RAC only data source. After about 30 seconds, all requests bail and generate this error in cfserver.log:
A non-SQL error occurred while requesting a connection from dbsource.
Timed out trying to establish connection
This happens with any RAC data source on the "bad" servers while the "good" servers don't have this problem. The "bad" server doesn't have any problems with direct (non-rac) Oracle data source.
Already tried:
Moving server connections around on a switch (rulling out bad switch port)
Copying driver from the healthy server (but it's the same installer anyway)
Changed from RAC to normal Oracle type data source - works perfectly. So at the moment I have 3 servers connecting to a specific oracle instance and the other 3 connecting to RAC.
Tried googling and searching forums and even Oracle metalink - nothing I could see relevant to this.
It's a shame that after spending a ton of money on CF8 upgrades and Oracle RAC, we can't really utilize fail-over on the database connection.
Any takers?
Thanks,
Henry

Transaction on Oracle 9i data source connection times out before JTA transaction

Hello,
I have a MDB with a long-running transaction (3600 second timeout).
In the MDB, I make a call to another EJB that has its transaction
attribute set to NotSupported (I do this because I need
non-transactional semantics in the called method).
If the EJB call take more than about a minute to complete, then I get a
datasource error when using the data source in the MDB after the return
(see error at bottom). However, if the call completes quickly, then I do
not get this error. It seems like the datasource connection somehow
times out, but I don't see where I can change this timeout.
pseudocode:
// timeout set to 3600 seconds
transactional MDB onMessage() {
// receive connection from Oracle BEA driver
// myEJB performLongOperation has transaction attribute
// set to NotSupported
String result = myEJB.performLongOperation();
// use connection from Oracle BEA driver
If the performLongOperation takes more than about a minute, then I get
the following error when using the connection after the operation:
Caused by: java.sql.SQLException: XA error: XAER_NOTA : The XID is not

I don't have contract customer support access with BEA, and thus I can't

OC4J -Time out and Oracle sequence problem

hi
i m using OC4J to access application which is using java as front and
and we using oracle sequence with cache as 20.
so when i accessing application thro' network my sequence skip from 20
mean 1-21-41-61 is it possible due to if lost connection opened from java for oracle thro' OC4J ? will it keep cache ?or lost ? is it really time out error?
if then hw to set time out in oracle?
u can refer below link
Re: ORABPEL-05002

i think i may be having the same problem. My table is savings entries out of order. I would assume that each row saved would be in sequence number order...instead it goes from like 963, 964, 678, 679, ....??? wonder why it would place new entries in front of older entries in the table???

Oracle Time Out - This is very interesting

We have run across a very curious situation. We have a series of statements (1 update, 1 insert, 1 call to a package) wrapped in a begin/end block. About 1 percent of these grouped statement timeout every day. Further research showed that only statements that were 2005 bytes long would time out. Even more strange was that if we retried the statement (in code; immediately after the time out occured) it would execute right away. The same statement pasted into SQL Plus (2005 bytes) completed instantly. Any thoughts on this? I have seen a number of postings discussing timeouts and mysterious random events like this but I have yet to see one explained.

First some questions:
* Is the database on the same machine as the JDBC client? If not, does the same problem occur on all clients?
* Does the problem only occur for your specific statements, or any set of statemensts that are 2005 bytes? Can you reproduce it with statements that don't make any modifications to the database?
* What JDBC drivers are you using? Have you tried the latest versions (ojdbc14.jar for Oracle). Are you using THIN or OCI? Can you try the other mechanism?
I presume you're talking about Oracle here. One of your best bets would be to use Oracle's trace facilities. If you're using OCI driver then you can do client side tracing (I think). You can also do server side tracing. You might identify what kind of conversation is occurring during the timeouts.
While I'm pretty sure this isn't going to be your problem, figured I'd share my story with you.
A number of years ago we had a client server database app that suffered a similar problem: A certin statement always failed with an Oracle network error message (although I'm not sure it was a timeout). We also discovered it was any statement of an exact byte size (the amount escapes me).
It turned out we had a network switch that dropped packets of an exact byte size. There was a bug in its OS. The manufacturer name also escapes me. Anyway, we uncovered the problem by using the "ping" command to ping the exact same packet size. The ping always failed. Note that we had to adjust the byte size passed to the ping command to account for the additional bytes added to the packet by ping.

Oracle Explorer connections times out -- cannot reconnect

Hello
How do I reconnect to the database about the connection times out?
Sometime I go to the Oracle Explorer to check some things out in the database, then switch to coding for a while -- maybe 30 minutes or so.
When I go back to the tree to check something, it says basically "not connected". I'm assuming it has timed out. However there doesn't seem to be an option to reconnect without closing Visual Studio and reopening it.
Am I missing something?
Thanks!
Horus

All you need to do is close the connection and reopen it. you do this by right clicking on the connection node in oracle explorer, from the menu that shows up select Close connection. again right click on the connection node in oracle explorer, from the menu that shows up select Open.

Time out problem while uploading large bpel processes into oracle soa suite

Hi everyone,
I'm using oracle soa suite 10.1.3.4.0 and I'm encountering time out problem while trying to upload a 5MB bpel process into my bpel process server located in the LAN network. The error is coming from apache common file upload.
Is there a way to increate the connection time out for oc4j to avoid this problem?
Thanks for any help.
Regards
Esfand

Hi Marc.
Thanks for your reply. I increased the transaction manager time-out but still I have the same problem. I believe this is something related to oc4j settings and related to upload bpel process. here is my stack trace output:

Database connec times out to Oracle cluster

When connecting from client machine to Oracle shared cluster, connection times out but cannot reconnect again,
What could cause this problem and what can be done regarding the timeout.
Thanks
Zaz

Hi,
Yes you can also use existing server as a part of first RAC node but would be better to have similar hardware configuration for all the cluster nodes. In order to migrate your database
from single instance with ASM to RAC database you have to follow below steps:-
Step 1> Install 11g Grid Infra software which will basically install clusterware ASM binaries ACFS
Step 2> Install database binaries in separate home in cluster mode
Step 3> Take the database backup which is running from non-clustered database home
Step 4> Use rconfig utility to convert single intsnace existing database running on one of cluster node into RAC database.
Please follow the below link how to use rconfig utility:- (Before proceding rconfig utility I would like to mention that both database binaries should be same. I mean older database home binaries and new installed database binaries in clustered mode. If both are not same then please first upgrade your database and then use rconfig utility).

Oracle IRM Desktop connection to server times out

I have installed IRM server on Linux VM and use https to make desktop client to connect to server. The desktop is running on Windows XP. I am getting connection time out very frequently when I refresh context or validate the server, which means the connectivity between desktop to server is not stable. It is very difficult to track down the root cause since there is no log for desktop client I can look at.
Any input?
-J

I have the same problem. Ping works fine(http://irmserver:16100/irm_desktop/ping). There are connections both on server and on the desktop (netstat shows it). In logs on the desktop there are:
"[5840] Сбой синхронизации для http://10.12.248.173:16100/irm_desktop
Сообщение пользователя: "Невозможно установить соединение с сервером IRM"
Код ошибки = 0x80040308 (0x80040E02)
<?xml version="1.0"?><wininet_error>12002</wininet_error>
[IrmBackground.exe]"
On server side there is no information in the server logs.
I am using IRM server - Oracle EL 4 x64, Oracle DB 11G x64, Oracle WL1034, irm server 11.1.1.4.0, irm desktop 11.1.20.86. Desktop on Windows XP Professional.
There is no proxy server between irm server and desktop
Although I found that the syncronization works after 2-3 attempts. It seems that the problem is in the short timeout of the irm desktop waitong for authorization when there are different platforms(Weblogic on linux and AD on MS)

Resource busy time out oracle message - Concurrency and Locks

I have a requirement to generate gapless invoice and receipt number in our application. so i have currently used the below approach.
a. created table with a column to hold the invoice and receipt number sequence value.
b. whenever transaction gets succeed. i will lock the table which holds the invoice number and receipt number inorder to avoid the sequential number slipages.
Issue
1. since the application belongs to online payment through portal by customers, when concurrent users trying to pay and while generating receipt number's, i am facing with "resource busy time out" message frequently. Here i noticed when user1 locks the table to access the receipt number value and session is not committed or rollback and another session user2 trying to access the same resource, in this scenario i am facing this error.
Frequency of encountering this error is low, but customer was telling us this error is show stopper and affects normal business.
Is there any alternative solution or method can be applied to overcome this problem?
Current SQL used in application
cursor <cursor name> is.
select <column_name>
into <variable>
from <table name>
for update of wait 5
update <table name> set <column name> = value + 1
where current of <cursor name>

Engage the business and inquire WHY this "requirement" exists. I have personally never seen an audit requirement wherein invoices MUST be devoid of gaps (that's not to say they do not exist, just that I've never seen one
They certainly must be unique, but that's what a sequence will do for you. If the business absolutely needs gapless information, then they will have to be willing to pay the price which is going to be longer transaction times (as requests queue in a busy system to get this sought after gapless resource). Your job is to explain this to them ... nothing comes without a cost.
The only thing you can really do (assuming you engage the business and the requirement doesn't change) is ensure the transactions are designed in such a manner that
1) they complete as fast as possible AND that the locking is done at the latest possible stage of the transaction
2) there is no user interaction (you cannot allow the users a "review" screen of any sort ... because users get silly sometimes and go for a coffee while reviewing things)

playback options->script->maximum delay 1500 seconds value
playback options->event playback->maximum 1500 seconds value
i tried restarting my pc. but it still failed after 120seconds. Any help will be highly appreciated.
Thanks in advance,
Hanson

Hi Avinnash,
Your time out setting may be very short.You may want to check your timeout Options (set it at 120 seconds) .
Options===> Current Script Options==> Playback==> General.
Hope it help.

Getting Connection Time out while connecting and with tnsping

Hello Experts,
I am new to Oracle world, so please go easy on me.
I installed Oracle 11 XE on Centos 6.4 VM. followed the official installation procedure and database was installed without any errors.
I am able to login to database through sqlplus and able to run sql queries.
Problem comes when i am trying to connect from sql developer or external application. i get Connection Time out error.
Below are the tnsnames.ora and listener.ora file content
# tnsnames.ora Network Configuration File:

I am stuck and don't know where else to check.
Could you guys please help me out here?
Thanks.

That tnsping error indicates several possible problems, most related to the setup for the client. Or network setup on the database server host.
Connecting to a database using sqlnet requires three things, the database host, the listener port, and the ORACLE_SID or instance SERVICE_NAME.
The tnsping utility is only concerned with the first two items, host and port. It will not perform an actual connection, and will not verify the tnsalias ORACLE_SID or SERVICE_NAME values.
An "OK" result from tnsping verifies that the specified host has a listener running at the specified port and it is servicing connections.
Since you're not getting an "OK" from tnsping, could be something is blocking the connection (i.e. firewall), the host= specification is not correct, or the port= spec is not correct. Note that host= must either be a valid and correct hostname, or a an IPv4 address. If IPv6 is in the mix, only the correct hostname will work. A hostname that resolves correctly.
Look at your network interface setup on the host, find its IP address, make sure the IP will `ping`, and try a new sqlnet.ora entry with the IPv4 address.
ifconfig -a
<interface>: flags=...
inet n.n.n.n
# in sqlnet.ora:
xe2 = ... host=n.n.n.n ...
tnsping xe2
... ok? ...

SSO Partner Application and Session Time out

Hi ,
We have an application on forums.oracle.com which is implementing the Authentication scheme as SSO, that is working well, now we want to implement Session Time out if the user is idle for some time and ask him to login again after the session fails, I have tried to implement this feature as given by Scott in the thread session timeout , well the problem is since we dont have a login page here how do we set the cookies owa_cookie.send(
name => 'HTMLDB_IDLE_SESSION',
value => to_char(sysdate+(20/1440),'DD-MON-YYYY HH24:MI:SS'),
expires => null,
path => '/',
domain => null
and where is the current point to implement it.
Any help on this is greatly welcome.
Thanks in Advance.

Naveen,
I don't remember how the solution works. But if you don't have a login page you can usually put code in the post-authentication process of your authentication scheme to do whatever the login page process would have done.
