Oracle Linux 6.3 and Oracle VM 3.0.3 : high "os thread startup" waits

Hi all,
we just installed Oracle Linux 6.3 as a PVM guest with Oracle VM 3.0.3.
The vm is acting as a dbserver.
We see high "os thread startup" wait times from statspack report. A 10-hour report shows:
Top 5 Timed Events Avg %Total
~~~~~~~~~~~~~~~~~~ wait Call
Event Waits Time (s) (ms) Time
CPU time 13,819 57.5
db file sequential read 1,839,279 5,791 3 24.1
enq: TX - row lock contention 1 664 ###### 2.8
os thread startup 1,350 451 334 1.9
control file sequential read 166,312 386 2 1.6
This seems to be an OS or virtualization issue: if i run some very simple commands like "ls " or "top", sometimes I see them hangig some seconds .
What should I check for ?
Thanks,
Andrea

This will sound silly, but: Make sure you aren't a victim of the "Some Linux machines have high CPU utilization after Leap Second insertion on July 1st". If your server was "doing NTP", this might have happened. You can google this, if you didn't hear of it. A reboot makes it go away.

Installing Grid Infrastructure 11.2.0.2 fails on Oracle Linux 5.6 and 6.0

Hi all,
We are in the process of building our new enterprise environment and tried to install the following:
Oracle Linux 6.0
Grid Infrastructure 11.2.0.2
ASM
OCFS2
Oracle RDBMS 11.2.0.2
Installation of Grid Infrastructure failed on Oracle Linux 6.0 and 5.6 as well. Is it because it's not yet certified for these Oracle Linux versions? Where can we find compatibility matrixes or certification information to find out which versions do work together? Been trying to find them with no success.
Thanks for any help!

I have recently installed Oracle 11.2.0.2 including ASM, which also installs Grid infrastructure under Oracle Linux 5.6 (default UEK kernel) without any problems. I installed the oracle-validated package prior to the Oracle installation.OEL 5.6 and 11.2..02 Grid Infrastructure installation (for x86_64) failed in our case. Have opened a SR several weeks ago for it, but no resolution. We since reverted back to OEL 5.5 for building and running this specific RAC.
There's also errors in OEL 5.6's Infiniband s/w stack. The openibd service fails to apply errata correctly because the o/s command used has since changed command line parameters. My guess is that testing happened solely on new h/w where this errata did not have to be applied, thus were not tested. Also, this service failed to start the srp_daemon (is critical for making sure that the storage layer works each and every time and does not cause stale connections that lead to command rejections from the storage server after a reboot of a RAC node)
I not only had to fix the openibd service to correctly apply the errata, but also write a separate srpd service that dealt with starting up and shutting down the srp_daemon.
Not very impressed with OEL 5.6 at all and it will be unlikely that we'll use it. And it raises a lot of concern whether OEL 6 would be a robust enough o/s for running our RAC systems.

Oracle Single Sign on and Oracle Internet Directory

Hello Gurus,
What is the relationship between Oracle Single Sign on and Oracle Internet Directory.
To my understanding, OID is required to install SSO.
If OID already exist, can we just install SSO and go on integrating it to existing OID.
Great Thanks,
vimal jain.

Hi Tim,
I've been working on this and could reproduce the issue with anonymous binds. A fix will be ready in 4.2.1.
So what I really need is the password used for login to pass to the is_member call.The P101_PASSWORD item does not save state. However, you can access the value during submit processing of the login page, for example in the post authentication function of your authentication scheme. People sometimes put code in there to query the user's groups (e.g. with apex_ldap.member_of2) and save them in an application. This item value can then be used in the authorization schemes.

Running Tuxedo8.0 on oracle 8.1.6 and oracle 10.2.0.2.0 on the same machine

Hello,
I have oracle 8.1.6 64 bit and oracle 10.2.0.2.0 64 bit
running on the same hp UX 11i 64-bit machine
I have installed Tuxedo 8.0 32bit on the same machine.
I have a working tuxedo 8.0 environment running against the 8.1.6 oracle
database
in the Tuxedo .../udataobj/RM file I have for the 8.1.6 environment the string
Oracle_XA:xaosw:-L${ORACLE_HOME}/lib -lclntsh
In oracle 8.1.6 home there are directories lib and lib64
but in oracle 10.2.0.2.0 home there are directories
lib and lib32
what string should I use for the oracle 10.2.0.2.0?
Oracle_XA:xaosw:-L${ORACLE_HOME}/lib32 -lclntsh maybe???
Must the string in the RM file for oracle always begin with the string
Oracle_XA?
If so is, possible at all to run the the binaries of one Tuxedo installation
against two different databases versions because the RM strings are similar in
the beginning but in 8.1.6 refer to the lib directory and in 10.2.0.2.0 refer
to the lib32 directory ?
Or do I need to have two installations of tuxedo8.0 binaries on the machine?
I have tried to for 10.2.0.2.0 the line (the Ora10_XA is only a try...)
Ora10_XA:xaosw:-L${ORACLE_HOME}/lib32 -lclntsh
in the RM file but when starting tuxedo I get:
$ cat /mnt04/edu/ressu/bin/xa_NULL06092006.trc
ORACLE XA: Version 10.2.0.1.0. RM name = 'Oracle_XA'.
111035.16584.0:
xaogetmod: XAER_INVAL; Invalid xa_info string.
Any comments on the matter appreciated.
rgds,
Jyri

Jyri,
The information before the first colon in the $TUXDIR/udataobj/RM file is
only used by the buildtms, buildserver, and buildclient programs to find the
line corresponding to the value of the -r option, so it should be OK to
specify different values for Oracle 8.1.6 and Oracle 10.2.0.2.0.
The information specfied in the OPENINFO string in the *GROUPS section of
the TUXCONFIG file must be of the form
OPENINFO="ORACLE_XA:Oracle_XA+...."
The strings ORACLE_XA and Oracle_XA cannot be changed, except for case. The
"...." can be replaced with parameters such as
SqlNet=NAMESesTm=100+LogDir=.+MaxCur=5 or whatever is used in your
applicatino. The "xaogetmod: XAER_INVAL: Invalid xa_info string" error you
are getting is due to an incorrect OPENINFO parameter.
If you are running a 32-bit version of Tuxedo you must link with the
${ORACLE_HOME}/lib32 library on 10gR2; if you are using a 64-bit version of
Tuxedo you must link with ${ORACLE_HOME}/lib library. The procedure is
similar for Oracle 8 except that it seems that the lib directory may be the
32-bit library in that version of Oracle.
32-bit and 64-bit binaries cannot be mixed under a single TUXDIR, but it is
possible to use multiple RMs or multiple versions of the same RM on the same
machine.
The syntax of the open string and the list of libraries to link with is
specified in the "Oracle Database Application Developer's Guide -
Fundamentals" in the "Developing Applications with Oracle XA" chapter.

Oracle Client 64-bit and Oracle Client 32-bit on the same server

Hi,
I have a Windows 2008 server 64-bit with Oracle Client 64-bit and Oracle Client 32-bit installed on different directories (D:\Oracle and D:\Oracle32)
Is it possible to define for certain applications to use the TNSNAMES entry from the 64-bit Oracle Client
and for other applications to use the TNSNAMES entry from the 32-bit Oracle Client
Once I installed the Oracle Client 32-bit (Oracle Client 64-bit version was already installed) and restarted the server I performed a TNSPING and it defaulted to the Oracle Client 32-bit installation path
Thanks,
Barry

Hello,
When you install a new client on a server, it will update the PATH variable, and add the ORACLE_HOME\bin path to it, at the first place. That explains why the tnsping use the last installed ORACLE_HOME.
What you can do if you want only to change the default path to the tnsnames is to set the environment variable TNS_ADMIN to the path where the tnsnames you want to use is located. You can modify this variable in your application if you want to use another tnsnames.
If you want switch from 32 bits to 64 bits client, then you have to modify the PATH variable.
Hope this will help.
Best regards,
Sylvie

Oracle 11.5.9 and Oracle 9i RAC fresh install

How is there an Oracle 11.5.9 and Oracle 9i RAC fresh install

No, except you upgrade your developer patchset which should not be an issue for the customized forms you have.
Can you please explain more in detail about this option and i will be thankful. Appreciate your help.Please see (Upgrading Developer 6i with Oracle Applications 11i [ID 125767.1]) for the steps you need to follow to upgrade your developer patchset.

"Oracle BPM Suite 11g" and "Oracle SOA Suite 11g" components

Dear Friends,
I am very confusing about the "Oracle BPM suite 11g" and "Oracle SOA Suite 11g" and would like your help on explanation as the following :
I have learn that In order to use "Oracle BPM Suite 11g" require to have "Oracle SOA Suite 11g" components to install first. Does it means that :
1) When we buy "Oracle BPM Suite 11g" , we automatically get the "Oracle SOA Suite 11g" components as well ?
2) IS it correct that these " these Oracle SOA Suite 11g components" are included :
(a) Oracle BAM
(b) Oracle Business Rules
(c) Oracle BPEL Manager
(d) Oracle Service Bus
(e) Oracle Complex Event Processing
3) Do we have a right to use all of these components listed in (2) ?
4) Then the answers in (3) is "YES", then Is it correct when the customer buy the "Oracle BPM Suite 11g" , they no need to buy "Oracle SOA 11g" any more when they would like to implements that applications based on SOA in the future (without using BPM) ?
5) What IF , the customer would like to start with "Oracle SOA Suite 11g" product and decide to buy only Oracle SOA Suite 11g first ; then later on in the future they would like to implement BPM projects in the future. Can you upgrade "Oracle SOA Suite 11g" to include "Oracle BPM Sutie 11g" and pay only the price different ?
I hope you can help providing the answers to these questions. THank you very much in advance.
Best Regards
Pearapon S.

This is a question best answered by your Oracle reseller or Oracle account manager to give you all the details but I hope this brief answer helps:
- The Unified Business Process Management Suite (BPM Suite 11g) includes: BPM Studio, BPM Composer, BPMN Service Engine and Workflow Extensions, BPM Process Spaces, and BPM Process Analytics.
- BPM Suite 11g requires the licensing of SOA Suite 11g for Oracle Middleware which requires a license for WebLogic Suite.
- You can license SOA Suite 11g now and license BPM Suite 11g later.
Since the products are layered, I don't see this cutting into SOA sales at all. My personal view is that BPM on top of SOA is brilliant since it provides easy integration between human and automated tasks, builds on many of the SOA concepts that are key for a successful BPM implementation (functional, not the Oracle product), and uses the same IDE. The synergies extend past easy use of services; the same business rules and human workflow components are used between both products.

Oracle 10g release 2 and Oracle Unbreakable Linux 5

I see in this forum some solutions but none works for me (I´m installing Oracle Unbreakable Linux 5 x64) to solve this problem I put libXp lib but the problem is the same.
The library is installed:
[root@SRVAXILAB072 oracle]# ll /usr/lib64/libXp.so.6
lrwxrwxrwx 1 root root 14 Aug 16 18:10 /usr/lib64/libXp.so.6 -> libXp.so.6.2.0
[root@SRVAXILAB072 oracle]#
But I think the installation process are searching in /usr/lib but I didn´t have the library in 32b I tried to copy to /usr/lib and another crazy ideas but didn’t work.
I read alot of post and guides for installation process but I didn´t see nothing to install Oracle in Oracle Unbreakable Linux 5
Some ideas??
If not..... I will try with Oracle Unbreakable linux 4 :(
Thanks
Best Regards

Well, I've not been in touch with installs on linux myself for a long time, but it seems you need a few 32-bit libs. Try installing libXp-1.0.0-8.i386.rpm.

I'm glad you did not take my remark to call you a Linux enthusiast in bad way. It certainly was not meant to be a bad comment, but it's was probably silly of me to make such a remark anyway. I do not take personally offence easily in a forum like this. No, if you want to offend me, post poor code and claim it as the best thing since slice bread. ;-)
I guess I strive to be liberal, but by definition I don't think I really fit into any political wing.Likewise. Find politics a necessary evil to keep abreast of - such as the election in the US.
Back to Linux and your example, I have used such interfaces for many years too. Unfortunately we often have to use what is provided. However, the reason for the text interface is no longer valid, unless your input device is only a text based terminal.Not as much the input device - heck, pure tty devices are pretty much a thing of the past. It is about the complexity of the infrastructure between you and the device you need to administer. And about the task you need to perform.
The connectivity can mean being unable to run a GUI - due to performance, firewalls, router configurations and so on. The task at hand could very well be easily done, using the relevant o/s commands via a command line interface.
I think there is nothing against a GUI app that runs on your PC to sends appropriate commands to a text interface over a slow serial link, apart from the effort that is required to interact with errors, etc.Much more complex than that. A terminal server is usually used - and it attaches to the serial/RS232 connections of multiple devices that need to be administered. It will typically reside on a separate management network too, and not on the local company/corporate intranet.
So for you to access a device to administer, you need an open firewall to the management network to reach the management server that handles the serial console connection for the device you want to administer. You need a valid o/s account on that terminal server. You need to use ssh to access the command line of that terminal server. You need to enter the relevant command that will attach your ssh session to the RS232 console connection to the device to administer.
There is no GUI app on your side that can not only automagically do all this for you, but also provide you with GUI admin widgets to send commands to the remote device. Even if that remote device being sysadmin'ed is Linux, different distros and different versions of the same distros, means different commands, variances in command line parameters for such commands, and so on.
A sysadmin that cannot deal with such situations, and need a GUI as a crutch to administer a device.. I for one will not call that person a sysadmin. I would call the person incompetent instead. Harsh views perhaps, but being sysadmin is an unforgiving job. A mistake, or inability to access a device and fix it using the bare minimum, could result in severe financial loss for the company.

Problem on Installing RAC System - Oracle Linux 6.2 and 11gR2

Folks,
Hello. I just start to install 4-nodes RAC system using VMplayer 3. The host Operating System is Windows 7.
The Guest OS is Oracle Linux 6.2.
Because my computer's hard disk does not have enough space, I install the Guest OS Oracle Linux 6.2 into a external hard disk. But its speed is very slow. It has taken more than 24 hours by now, but still don't finish installing Oracle Linux 6.2.
Do any folk understand what's going on ? Is there any problem on Oracle Linux 6.2 ?
