Oracle RAC summer time

Hi!
Environment: Oracle RAC 9.2.0.7 in AIX 5.3.
I have a database with the following configuration:
$ srvctl getenv database -d mydb
TZ=NFT-1DFT
Because of in Spain we have summer time, I need change it. (TZ=NFT-1DFT is only valid for winter).
I have tried:
$ srvctl setenv database -d mydb -t TZ="NFT-1DFT,M3.5.0,M10.5.0"
But it does not work:
ava.lang.StringIndexOutOfBoundsException: String index out of range: -1
at java.lang.String.substring(String.java)
at oracle.ops.opsctl.SetenvAction.parseNameValues(SetenvAction.java:204)
at oracle.ops.opsctl.SetenvAction.executeDatabase(SetenvAction.java:80)
at oracle.ops.opsctl.Action.execute(Action.java:92)
at oracle.ops.opsctl.OPSCTLDriver.execute(OPSCTLDriver.java:223)
at oracle.ops.opsctl.OPSCTLDriver.main(OPSCTLDriver.java:121)
¿Could anybody help me?
Thanks in advance.

Unless you are on R12.1, you can't control this value. If you are on 12.1, Default Timecard Period has been added to preference Self Service Timecard Period for a Worker, where the following options are available:
Period on or after system date

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

Regarding Hangcheck timer configuration in Oracle RAC 10g r2 installation

Hi,
Is it necessary to configure hangcheck timer in Oracle RAC 10g R2 installation .
Can somebody guide when we should install the hangcheck timer in Linux oracle 10g R2.
Best Regards
Gupteswar Prasad Mishra
Edited by: Gupteswar on Jan 25, 2010 8:42 PM

yes, its recommended to configure hangcheck timer in RAC configuration
Configure the Hangcheck Timer
The hang-check timer is loaded into the Linux kernel and checks if the system hangs. It will set a timer and check the timer after a certain amount of time. There is a configurable threshold to hang-check that, if exceeded will reboot the machine. Although the hangcheck-timer module is not required for Oracle Clusterware (Cluster Manager) operation, it is highly recommended by Oracle.
cat /etc/rc.local
modprobe hangcheck-timer hangcheck_tick=1 hangcheck_margin=10 hangcheck_reboot=1

Oracle Upgrade from Oracle RAC 9.2.0.6 to Oracle 10.2.0.4

Hi All,
Currently, we are running 4 node Oracle RAC environment with below mentioned configuration.
OS: Sun Solaris 5.9
Hardware: Sun E2900
Oracle Version: 9.2.0.6
Veritas Cluster Server: 4.1
We want to upgrade Oracle version to 10g, and currently analyzing the options to perform this. The current database size is 1TB appx and we want to spend minimum application shutdown time running on this database.
As part of upgrade, we also need to upgrade Veritas Cluster Server from 4.1 to 5.1 to support Oracle 10g. It would be great help,, if someone can pass some guideline to perform this task.
We are currently thinking about piecemeal approach, where we can upgrade each node individually and then put them back to cluster. There are some complexities involved, and its really high risk approach.
Thanks a lot in advance for help
Regards,
Manoj

Orcale 10g RAC requires you to install Oracle Clusterware. Oracle Supports running it along side a 3rd party clustering software. Not sure why you're so anxious to upgrade Veritas Clusterware when it will be trivial on the 10g db hosts.

Try this. It worked for me.
Please keep in mind that you will need wait till each step finishes successfully before move to next one
For Step1 and 2, you can skip node(s) on which you didn't execute root.sh yet.
Step 1: As root, run "$GRID_HOME/crs/install/rootcrs.pl -verbose -deconfig -force" on all nodes, except the last one.
Step 2: As root, run "$GRID_HOME/crs/install/rootcrs.pl -verbose -deconfig -force -lastnode" on last node. This command will zero out OCR and VD disk also.
Step 3: As root, run $GRID_HOME/root.sh on all node one by one

Oracle RAC with ASM install failure

Hi Guy's
I've just rebuilt an Oracle RAC system, i've built this system many times and have the build documented. I usually follow the build doc to the tee and everything works fine. I have now been asked to rebuild the system to go into the production evironment. This is a two server standard RAC setup using ASM. We have a HP MSA500 shared storage setup. I've run the cluster verification tool and all the checks have come out fine. Whilst installing the clusterware i get a failed error message whilst it try's to confiure the Oracle Clusterware Configuration Assistant.
The error message i get is:
Command = C:\Windows\system 32\cmd\C Call E:\Oracle\Product\10.2.0\crs\install\crssetup.config.bat
PROT-1:Failed to intialize OCR Config
STEP 1 Checking status of CRS cluster
STEP 2 Creating directories (E:\Oracle\Product\10.2.0\Crs
STEP 3 Configuring OCR repository
ocr upgrade failed with (-1)
I've done this build many times and never seen this error. From what i've read on the internet it looks like it could be something up with my shared storage but i dont know what.
Any help would be greatly appreciated
Thanks

Problem statement:
ORA-29701 DURING DATABASE CREATION AFTER APPLYING 9.2.0.6 PATCHSET
*** 03/25/05 07:32 am ***
TAR:
PROBLEM:
Customer applied 9.2.0.6 patchset over 9.2.0.4 patchset.
While creating the database, customer receives following error:
ORA-29701: unable to connect to Cluster Manager
However, if customer goes from 9.2.0.4 -> 9.2.0.5 -> 9.2.0.6, the problem does not occur.
DIAGNOSTIC ANALYSIS:
It seems that the problem is with libskgxn9.so shared library.
For 9.2.0.4 -> 9.2.0.5 -> 9.2.0.6, the install log shows the following:

This means that while patching from 9.2.0.4 -> 9.2.0.5, Installer copies the libcmdll.so library into libskgxn9.so, while patching from 9.2.0.4 -> 9.2.0.6 does not.
ORACM is located in /app/oracle/ORACM which is different than ORACLE_HOME in customer's environment.
WORKAROUND:
Customer is using the following workaround:
cd $ORACLE_HOME/rdbms/lib make -f ins_rdbms.mk rac_on ioracle ipc_udp

How to install oracle rac on linux using virtualbox

Hi,
I have recently started working on oracle rac
I have system with 64 bit os windows 7 installed
core i3 processor with 6 gb of ram
I want to install grid infrastructure on linux running as a virtual machine
how can I install and configure it? Please help me .
can ubuntu work as a virtual machine for oracle rac?

Hi,
I suggest you use Oracle Enterprise Linux on your lab. There are a lot of step-by-step guide to install RAC on OEL. A good example is by Tim Hall, search Google for "Tim Hall Oracle Database RAC Installation".

Reporting Services connections are getting dropped by Oracle RAC

My current customer is using Oracle RAC (11g) for their data store. They currently are using SQL Server Reporting Services to connect to it. We are experiencing an issue where the connection appears to be redirected at the server which causes the connection to be lost with the client.
I am curious if this is "by design" or if we need to review some configuration settings to better handle this.
We have 3 VIPs fronting the RAC and they are all specified in the TNSNAMES.ORA file.
Any feedback or input on this issue would be greatly appreciated.

Hi,
I suggest you look at:
http://www.oracle.com/technetwork/database/clustering/overview/awm11gr2-130711.pdf
and the similar paper from 11.1:
http://www.oracle.com/technetwork/database/clustering/overview/awmrac11g-133673.pdf
This explains the basic concept, of how clients should connect to the database, and probably clarifies your issue.
In generall Oracle will not redirect during runtime, only during connection time.
This however should not be of an issue, if you connect to a service. (You shouldn't connect to a SID since 8.1.7 anymore).

Hello,
The errors you are receiving are typically a result of not following our published MOS note and our documentation. It’s important in order for Oracle E-Business Suite systems to be properly recognized by E-Business Suite Plug-in, AutoConfig must be enabled and updated on all nodes. You should prevalidate your system before the running discovery to help ensure success of the discovery process. These tests check that context files, context variables, users, and components are set up correctly in the system for successful discovery.
For more information on both topics refer to:
•     Getting Started with Oracle Application Management Pack (AMP) for Oracle E-Business Suite, Release 12.1.0.1 (Doc ID 1434392.1)
•     Oracle Application Management Pack for Oracle E-Business Suite Guide Release 12.1.0.1.0 Part No. E28715-03 October
If you are still experiencing errors after reviewing our documentation and taking the appropriate steps to prevalidate your system consider filing a Service Request with Support.

Oracle RAC Nodes getting reboot in case of preferred controller failed

When we are disconnecting both Fiber cable from preferred Controller A or plugging out Controller A card from Disk Array(IBM DS 4300), After 90 seconds both the servers are rebooting.
In this time complete RAC network is going out of service for approx 5 minutes.After reboot both servers are coming with both instances without any manual intervention
Its a critical issue for us because we are loosing High Availability, Let us know how we can resolve this critical issue.
Detail of Network:
1. Software- Oracle 10g Release2
2. OS- Redhat Linux 3 (Kernel Version-2.4.21-27.ELsmp)
3. Shared Storage- IBM DS 4300.
4. Multipathing Driver - RDAC (rdac-LINUX-09.00 A5.13)
4. Nodes- IBM 346
5. Databse on ASM
6. ASM,OCR & Voting Disk Preferred controller is A.
7. Hangcheck timer value is 210 seconds.
8. Both Server available with 2 HBA port . I HBA port is connected with Controller A and Seconfd HBA port is connected with Controller B of SAN Disk Array.
As per my understanding,
Voting disk resides in Disk Array and Controller A is preferred owner of Voting Disk LUN.. When i am disconnecting both fiber cable from preferred controller A , then Both Nodes Clusterware software trying to contact with Voting Disk, When they are unable to contact with Voting disk in specfic time period, they are going for reboot.
I tested Controller failure testing with Oracle RAC software as well without Oracle. Without Oracle its working fine and reason behind, in that time Disk Array is waiting for approx 300 seconds for changing preferred controlller from A to B.
But With Oracle, Clusterware Software reboot both nodes before Controller can shift from A to B.
So if i conclude,the tech who has good understanding of Oracle Clusterware on Linux OS & IBM RDAC multipath driver can help me.
when we install Oracle RAC on Linux, it is required to configure hangcheck timer.
Oracle recomends 180 second.
It means if one of node is hanging, then second node will wait for 180 seconds, if within 180 seconds ,it is not able to resolve this situation then it will reboot hung node.
I think Hangcheck timer configuration reuired only with Linux OS.
Configuration File
cat >> /etc/rc.d/rc.local << EOF
modprobe hangcheck-timer hangcheck_tick=15 hangcheck_margin=60

Sorry
Hangcheck timer is

Oracle RAC - Not getting performance(TPS) as we expect on insert/update

Hi All,
We got a problem while executing insert/update and delete queries with Oracle RAC system, we are not getting the TPS as we expected in Oracle RAC. The TPS of Oracle RAC (for insert/update and delete ) is less than as that of
single oracle system.
But while executing select queries, we are getting almost double TPS as that of Single Oracle System.
We have done server side and client side load balancing.
Can anyone knows to solve this strange behaviour? Shall we need to perform any other settings in ASM/ Oracle Nodes
for better performance on insert/update and delete queries.
The following is the Oracle RAC configuration
OS & Hardware :Windows 2008 R2 , Core 2 Du0 2.66GHz , 4 GB
Software : Oracle 11g 64 Bit R2 , Oracle Clusterware & ASM , Microsoft iSCSI initiator.
Storage Simulation : Xeon 4GB , 240 GB ,Win 2008 R2, Microsoft iSCSI Traget
Please help me to solve this. We are almost stuck with this situation.
Thanks
Roy

Gig Ethernet V/S SCI as Cluster Private Interconnect for Oracle RAC

Hello Gurus
Can any one pls confirm if it's possible to configure 2 or more Gigabit Ethernet interconnects ( Sun Cluster 3.1 Private Interconnects) on a E6900 cluster ?
It's for a High Availability requirement of Oracle 9i RAC. i need to know ,
1) can i use gigabit ethernet as Private cluster interconnect for Deploying Oracle RAC on E6900 ?
2) What is the recommended Private Cluster Interconnect for Oracle RAC ? GiG ethernet or SCI with RSM ?
3) How about the scenarios where one can have say 3 X Gig Ethernet V/S 2 X SCI , as their cluster's Private Interconnects ?
4) How the Interconnect traffic gets distributed amongest the multiple GigaBit ethernet Interconnects ( For oracle RAC) , & is anything required to be done at oracle Rac Level to enable Oracle to recognise that there are multiple interconnect cards it needs to start utilizing all of the GigaBit ethernet Interfaces for transfering packets ?
5) what would happen to Oracle RAC if one of the Gigabit ethernet private interconnects fails
Have tried searching for this info but could not locate any doc that can precisely clarify these doubts that i have .........
thanks for the patience

Tim
Can any one pls confirm if it's possible to configure
2 or more Gigabit Ethernet interconnects ( Sun
Cluster 3.1 Private Interconnects) on a E6900
cluster ?Yes, absolutely. You can configure up to 6 NICs for the private networks. Traffic is automatically striped across them if you specify clprivnet0 to Oracle RAC (9i or 10g). That is TCP connections and UDP messages.
It's for a High Availability requirement of Oracle
9i RAC. i need to know ,
1) can i use gigabit ethernet as Private cluster
interconnect for Deploying Oracle RAC on E6900 ? Yes, definitely.
2) What is the recommended Private Cluster
Interconnect for Oracle RAC ? GiG ethernet or SCI
with RSM ? SCI is or is in the process of being EOL'ed. Gigabit is usually sufficient. Longer term you may want to consider Infiniband or 10 Gigabit ethernet with RDS.
3) How about the scenarios where one can have say 3 X
Gig Ethernet V/S 2 X SCI , as their cluster's
Private Interconnects ? I would still go for 3 x GbE because it is usually cheaper and will probably work just as well. The latency and bandwidth differences are often masked by the performance of the software higher up the stack. In short, unless you tuned the heck out of your application and just about everything else, don't worry too much about the difference between GbE and SCI.
4) How the Interconnect traffic gets distributed
amongest the multiple GigaBit ethernet Interconnects
( For oracle RAC) , & is anything required to be done
at oracle Rac Level to enable Oracle to recognise
that there are multiple interconnect cards it needs
to start utilizing all of the GigaBit ethernet
Interfaces for transfering packets ?You don't need to do anything at the Oracle level. That's the beauty of using Oracle RAC with Sun Cluster as opposed to RAC on its own. The striping takes place automatically and transparently behind the scenes.
5) what would happen to Oracle RAC if one of the
Gigabit ethernet private interconnects fails It's completely transparent. Oracle will never see the failure.
Have tried searching for this info but could not
locate any doc that can precisely clarify these
doubts that i have .........This is all covered in a paper that I have just completed and should be published after Christmas. Unfortunately, I cannot give out the paper yet.
thanks for the patience

Oracle RAC Interconnect, PowerVM VLANs, and the Limit of 20

Hello,
Our company has a requirement to build a multitude of Oracle RAC clusters on AIX using Power VM on 770s and 795 hardware.
We presently have 802.1q trunking configured on our Virtual I/O Servers, and have currently consumed 12 of 20 allowed VLANs for a virtual ethernet adapter. We have read the Oracle RAC FAQ on Oracle Metalink and it seems to otherwise discourage the use of sharing these interconnect VLANs between different clusters. This puts us in a scalability bind; IBM limits VLANs to 20 and Oracle says there is a one-to-one relationship between VLANs and subnets and RAC clusters. We must assume we have a fixed number of network interfaces available and that we absolutely have to leverage virtualized network hardware in order to build these environments. "add more network adapters to VIO" isn't an acceptable solution for us.
Does anyone know if Oracle can afford any flexibility which would allow us to host multiple Oracle RAC interconnects on the same 802.1q trunk VLAN? We will independently guarantee the bandwidth, latency, and redundancy requirements are met for proper Oracle RAC performance, however we don't want a design "flaw" to cause us supportability issues in the future.
We'd like it very much if we could have a bunch of two-node clusters all sharing the same private interconnect. For example:
Cluster 1, node 1: 192.168.16.2 / 255.255.255.0 / VLAN 16
Cluster 1, node 2: 192.168.16.3 / 255.255.255.0 / VLAN 16
Cluster 2, node 1: 192.168.16.4 / 255.255.255.0 / VLAN 16
Cluster 2, node 2: 192.168.16.5 / 255.255.255.0 / VLAN 16
Cluster 3, node 1: 192.168.16.6 / 255.255.255.0 / VLAN 16
Cluster 3, node 2: 192.168.16.7 / 255.255.255.0 / VLAN 16
Cluster 4, node 1: 192.168.16.8 / 255.255.255.0 / VLAN 16
Cluster 4, node 2: 192.168.16.9 / 255.255.255.0 / VLAN 16
etc.
Whereas the concern is that Oracle Corp will only support us if we do this:
Cluster 1, node 1: 192.168.16.2 / 255.255.255.0 / VLAN 16
Cluster 1, node 2: 192.168.16.3 / 255.255.255.0 / VLAN 16
Cluster 2, node 1: 192.168.17.2 / 255.255.255.0 / VLAN 17

Which eats one VLAN per RAC cluster.

Thank you for your answer!!
I think I roughly understand the argument behind a 2-node RAC and a 3-node or greater RAC. We, unfortunately, were provided with two physical pieces of hardware to virtualize to support production (and two more to support non-production) and as a result we really have no place to host a third RAC node without placing it within the same "failure domain" (I hate that term) as one of the other nodes.
My role is primarily as a system engineer, and, generally speaking, our main goals are eliminating single points of failure. We may be misusing 2-node RACs to eliminate single points of failure since it seems to violate the real intentions behind RAC, which is used more appropriately to scale wide to many nodes. Unfortunately, we've scaled out to only two nodes, and opted to scale these two nodes up, making them huge with many CPUs and lots of memory.
Other options, notably the active-passive failover cluster we have in HACMP or PowerHA on the AIX / IBM Power platform is unattractive as the standby node drives no resources yet must consume CPU and memory resources so that it is prepared for a failover of the primary node. We use HACMP / PowerHA with Oracle and it works nice, however Oracle RAC, even in a two-node configuration, drives load on both nodes unlike with an active-passive clustering technology.
All that aside, I am posing the question to both IBM, our Oracle DBAs (whom will ask Oracle Support). Typically the answers we get vary widely depending on the experience and skill level of the support personnel we get on both the Oracle and IBM sides... so on a suggestion from a colleague (Hi Kevin!) I posted here. I'm concerned that the answer from Oracle Support will unthinkingly be "you can't do that, my script says to tell you the absolute most rigid interpretation of the support document" while all the time the same document talks of the use of NFS and/or iSCSI storage eye roll
We have a massive deployment of Oracle EBS and honestly the interconnect doesn't even touch 100mbit speeds even though the configuration has been checked multiple times by Oracle and IBM and with the knowledge that Oracle EBS is supposed to heavily leverage RAC. I haven't met a single person who doesn't look at our environment and suggest jumbo frames. It's a joke at this point... comments like "OMG YOU DON'T HAVE JUMBO FRAMES" and/or "OMG YOU'RE NOT USING INFINIBAND WHATTA NOOB" are commonplace when new DBAs are hired. I maintain that the utilization numbers don't support this.
I can tell you that we have 8Gb fiber channel storage and 10Gb network connectivity. I would probably assume that there were a bottleneck in the storage infrastructure first. But alas, I digress.
Mainly I'm looking for a real-world answer to this question. Aside from violating every last recommendation and making oracle support folk gently weep at the suggestion, are there any issues with sharing interconnects between RAC environments that will prevent it's functionality and/or reduce it's stability?
We have rapid spanning tree configured, as far as I know, and our network folks have tuned the timers razor thin. We have Nexus 5k and Nexus 7k network infrastructure. The typical issues you'd fine with standard spanning tree really don't affect us because our network people are just that damn good.

Failover not happening the Oracle RAC 10g

Hi All,
I am new to RAC.
I have installed Oracle RAC 10g on Redhat Linux 4.0. Till yesterday failover was happening that is when i stopped one instance on node01 the vip of node01 was transferred to node02.This was shown using ifconfig -a but now that is now happening.Don't know as what has happened.Can you please help me out

Since you didn't say "thank you", I assumed my time was of no value to you.
However, I shall try again.
There is no relationship between instance failure and VIP failover. How can there be? What if you are running ten instances on each node, and one fails? Would you want the VIP to relocate? And I've already told you how to test it: kill the node. Just reboot it.
