Identify the OCR master node for 11.2
My customer is on 11.1.0.6 RAC DB with 11.2 CRS+ASM and interested in finding "OCR master node" at any point time.
I noticed that one way is to identify the OCR master node is to search
$ORA_CRS_HOME/log/hostname/crsd/crsd.log
file for the line "I AM THE NEW OCR MASTER" or "MASTER" with the most recent timestamp. Does this applicable 11.2 Release ?
and what are the other alternate ways to identify master node.
Thanks in advance.
Hi,
as it was mentioned before, you can use the RAC FAQ Oracle Support Note to determine the masters in a RAC system. Except that this note would not elaborate on the OCR Master that you are asking for (OCR Writer as it is called in the documentation these days) in this context.
However, your command to check $ORA_CRS_HOME/log/hostname/crsd/crsd.log works and the message is pretty much the same in 11.2 as it was pre-11.2. However, note that only checking the CRSD.log may not always tell you the OCR master all the time. Reason: The CRSD.log is used in a rolling fashion. Once the log entries have reached approx. 50MB, it is rolled over to crsd.l01 or something like that and a fresh crsd.log is used. 10 archived logs are maintained.
For an average cluster this will last for a while, but in general, there might be a time when all these logs have been used and the OCR master has never been changed. In this case, you cannot use the logs anymore. Luckily, you should not have to find the OCR Master all the time. Why are you interested in knowing which node the OCR Master resides on all the time?
At least, you should therefore cat all crsd.l* files under the respective directory on all nodes to determine this. But again, that should not be necessary.
Hope that helps. Thanks,
Markus

TUXEDO11 in MP mode can't boot TMS_ORA on the non-master node
I have my Tuxedo 11 installed on Ubuntu9.10 server as the master node (SITE1) and on CentOS6.2 as the non-master node (SITE2). The client program is using WSL to communicate with the servers. Tuxedo 11 has no patch, and both Tuxedo11 and Oracle10gR2 are 32 bits running on 32 bits OS.
On both node a TMS_ORA associated with an ORACLE 10gR2 database was installed. When I issue "tmboot -y", the servers on the master node booted normally, however, the TMS_ORA server and server that using TMS_ORA on SITE2 reported "Assume started (pipe). ". There is no core file for these servers on SITE2 and in ULOG on SITE2 there is no Error or Warning concerning the failure starting of TMS_ORA.
In order to check my servers and TMS_ORA works OK on SITE2, I used the master command under tmadmin to first swap the master and non-master node, and after the migration is successful, on SITE2 I issued "tmshutdown -cy" command then "tmboot -y" command. Surprisingly, all the servers booted correctly on both nodes. Then I migrate the master node back to SITE1 and the servers are still there alive and my client program can successfully call these servers which means the TMS_ORA and server using TMS_ORA on both nodes works fine.
The problem is, when I "tmshutdown -s server" (those on SITE2, either TMS_ORA or server using TMS_ORA), then using "tmboot -s server" to boot them (those on SITE2, either TMS_ORA or server using TMS_ORA) I got "Assume started (pipe). " reported and those server process didn't appear on SITE2.
It seems that I can't boot TMS_ORA on SITE2 from the master node SITE1 but can boot all the servers correctly if SITE2 are acting as the master node. Server that don't use TMS_ORA on SITE2 can be booted successfully from SITE1.
Can anybody figure out what's wrong? Thanks in advance.
Best regards,
Orlando

Need help on how to identify the latest timestamp ran for the WorkBooks
I know some tables to identify the workbooks when they are created.But this tables are not updating If we ran the workbook today.
for example, : if we created workbook & saved on 05/25/2009 or opening old WB.After that if we ran same workbook on 05/26/2009 then system has to update the latest timestamp as last ran.but iam unable to find this timestamps for workbooks.
WB are maitained in RSDDSTAT.here i can able to find when it was last changed but not the latest timestamps.Our requirement to find the latest timestamp ran for the WorkBooks from last one year, which are using.
below are the tables to identify when the workbook was created and other details:
RSRWBINDEX List of binary large objects (Excel workbooks)
RSRWBINDEXT Titles of binary objects (Excel workbooks)
RSRWBSTORE Storage for binary large objects (Excel workbooks)
RSRWBTEMPLATE Assignment of Excel workbooks as personal templates
RSRWORKBOOK Where-used list for reports in workbooks
Thanks in advance
MaheshAny Updates,
I got one more table to identify WB,

OCM for Revesion level in the Material Master and for the BOM
Hello,
I use My SAP 6.
I have implemented OCM. It's used for 2 things:
- The first is for revision level in the Material Master.
- the second is for the BOM.
Today, the customizing is good, it's work.
My need is to have the same change number for those 2 evolutions: for the material master evolution and for the BOM evolution.
It's possible, and how?
Thanks for your answers.
BérengerI do not think this is possible. Service level is usually used for safety stock planning.

Identifying the correct MIME type for file uploads
How does Apex identify the MIME type of an uploaded file? I have a page that uploads a file and accesses it via APEX_APPLICATION_FILES. That works fine. The problem is that, for certain file types, the mime_types column is "application/octet-stream" instead of the correct file type. I think it's using the Content-Type from the client browser, though I'm not quite sure. Is there any way to override this server-side in Apex?
I'm running Apex with mod_plsql. Adding an AddType directive to Apache and adding the correct association to the mime.types file did not work.Hi,
I also noticed this - it seems that Microsoft's 4 char extensions like .docx are not being recognized by application type so that either the web server or mod-plsql is defaulting to the "application/octet-stream" mime type which refers to a file with binary content - instead of the traditional "application/msword" mime type you would expect.
If you know, at the point of insert into your database table, both the mime type and file name, one workaround would be to check if the mime type is 'application/octet-stream' and the file's extension is ".docx" or other likely extensions and then treat it as mime type 'application/msword", etc.
Not really a solution but might be sufficient workaround depending on your situation.

Alsa/pulseaudio - keep the same master volume for speaker&headphones
Hello,
I have laptop Asus N550JV.
I installed alsa ant pulseaudio (alsa-utils and pulseaudio, nothing else, no pulseaudio-alsa plugin, because I noticed that it causes me more problems rather than reduces them.
the problem is that I want to keep Master audio channel untouched. If I listen through speaker, I could set master volume to 50%, then I can plug in headphones, set volume to 100%, then I can unplug headphones, the sound will play still at 100% THROUGH SPEAKER for about 0.5 sec. and after 0.5sec it will set back to 50% as I set when I was listening through speakers.
My question is, how can I fix this problem. I see that there are 2 ways to fix this:
1. make a lag time (delay) to switch from headphones to speakers.
2. keep the same master audio volume for both headphones and speakers.
Any ideas? I think the second solution would be easier to make, but I dunno howHi,
I am having the same problem with the ringer volume automatically being reset to some other volume. In my case the ringer volume slider under "Settings" + "Sounds" seems to be tied to the iPod speaker volume.
For example, I go in to "Settings" + "Sounds" and I set the ringer volume to maximum, I return to the home screen and then back to settings to make sure the volume is still the same (and it is), and then I go to iPod and play a track via the built-in speakers (i.e., no headphones). If I happen to change the iPod speaker volume and then stop playback and return to "Settings" + "Sounds" from the home screen I find that the ringer volume has been reset to whatever volume level I had previously set the iPod speaker volume.
I had assumed that these two volume settings were independent . Certainly, changing the ringer volume does NOT affect the iPod speaker volume, but setting the iPod speaker volume DOES affect the ringer volume.
Hopefully this is corrected in the first firmware update.

How do I identify the actual /dev nodes in use by ASM?
I'm using ASM on LUNs from an EMC SAN, fronted by PowerPath. Right now I have only one fiber path to the SAN, so /dev/emcpowera3 maps directly to /dev/sda3, for example. Oracle had a typo in what they told me to do in /etc/sysconfig/oracleasm*, so the scan picks up both devices.
#/etc/init.d/oracleasm querydisk -p ASMVOL_01
Disk "ASMVOL_01" is a valid ASM disk
/dev/emcpowera3: LABEL="ASMVOL_01" TYPE="oracleasm"
/dev/sda3: LABEL="ASMVOL_01" TYPE="oracleasm"
But I don't think it can be using both. How do I see which one it's actually using?
*They said:
ORACLEASM_SCANORDER="emcpower*"
ORACLEASM_SCANEXCLUDE="sd"
But I think that should be "sd*".Powerpath supports multiple I/O paths. Most HBA (Fibre Channel PCI cards) have dual ports.
This means 2 fibres running from the server into the FC switch(es). And more than one I/O path for that server to read/write a SAN LUN.
That SAN LUN will be seen multiple times by the sever - so it will create multiple scsi devices (in the +/dev/+ directory). One device for each I/O path.
There are 2 basic reasons why you should not use these scsi devices directly.
They can and do change device names after each reboot. The sequence the SAN LUNs are named in, depends on how the I/O fabric layer enumerates the LUNs when the kernel runs a device discovery on each I/O path. So LUN1 can be device sdg and sdk on one boot, and the same LUN1 can be sde and sdx on another boot. There is thus no naming consistency which makes it very difficult to use the device names directly as these names change.
The second reason is redundancy. If you use device sdg and that I/O path fails, your s/w using that device fails. Despite a second path being available to the LUN on the SAN via device sdk.
Powerpath (and Open Source Multipath) addresses this issue. The unique scsi ID of each device is determined. The devices with the same ID are I/O paths to the same LUN. A single logical device (an emcpower* device) is created - and it serves as the interface to the LUN, supporting all the I/O paths to the LUN (providing load balancing, and redundancy should an I/O path fail).
The powermt command (if I recall correctly) will show you how this logical device is configured and what scsi devices are used as I/O paths to the EMC LUN.
Personally - we do not use PowerPath any more for a number of years now. We instead use the Open Source Multipath solution. This was build for very large Linux clusters (1000's of nodes and Pentabytes of SAN storage) and is now a standard driver in the Enterprise distros of the Linux kernel. It works fine with EMC (we have used it with Clariion, Symmetrix SANs, and currently with VNX SANs).
Multipath does not taint the kernel. Multipath allows for far easier kernel upgrades. Multipath supports a number of different I/O fabric layers transparently. Multipath is very easy to configure. -
Hello,
I have two nodes rac setup. I just need to change the master node to different node in the cluster. How to change the master node?
Please help me out.Hi,
Master Node not exist on RAC and I have pretty sure you are not talking about "OCR Master", you are talking about RESOURCE MASTER.
The only thing closest to something like a "Master" is that only one node has the role to update the Oracle Cluster Registry (OCR), all other nodes only read the OCR.
However this is just a role, which can easily switch between the nodes (but is normally fix as long as the responsible nodes lives).
This node hover is then called OCR master.
How do I change node which hold "OCR Master"?
You can't decide that and you can't change that manually the Clusterware do it automatically without human intervention.
OCR Master is not a MASTER NODE it's only a role.
Good answer here:
Re: Identify the OCR master node for 11.2
Re: which node will become master
Please don't confuse the concept of MASTER OCR with RESOURCE MASTER (e.g Data Block).
All nodes hold MASTER RESOURCE, because that I said : all nodes are equal.
With "billions" of data block spread out in memory of cluster (SGA Instances), one node maintains extensive information (i.e Lock, Version, etc) about a particular resource (i.e a data block).
So, one node has master resource of data block "data_01" the other node has a master resource of data block "data_02" and so on. If a node which hold master resource fails (shutdown) GCS choose other node in the cluster to be a MASTER Resource of that particular resource.

BDB Native Version 5.0.21 - asynchronous write at the master node
Hi There,
As part of performance tuning, we think of introducing asynchronous write capabilities at the master node in replication code that uses BDB native edition (11g).
Are there any known issues with the asynchronous write at the master node? We'd like to confirm with Oracle before we promote to production.
For asynchronous write at the master node we have configured a TaskExecutor with the following configuration:
<bean id="MasterAsynchronousWriteTaskExecutor" class="org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor">
<property name="corePoolSize" value="3"/>
<property name="maxPoolSize" value="10"/>
<property name="daemon" value="true"/>
<property name="queueCapacity" value="200000"/>
<property name="threadNamePrefix" value="Master_Entity_Writer_Thread"/>
<property name="threadGroupName" value="BDBMasterWriterThreads"/>
</bean>
Local test showed no issues. Please let us know at the EARLIEST convenience if there are any changes required to corePoolSize, “maxPoolSize” and “queueCapacity” values as a result of asynchronous write.
To summarize, 2 questions:
1) Are there any known issues with the asynchronous write at the master node for BDB Native, version 5.0.21?
2) If there are no issues, are any changes required to corePoolSize, “maxPoolSize” and “queueCapacity” values as a result of asynchronous write, and based on the configuration above?
Thank you!Hello,
If you have not already, please take a look at the documentation
on "Database and log file archival" at:
http://download.oracle.com/docs/cd/E17076_02/html/programmer_reference/transapp_archival.html
Are you periodically creating backups of your database files?
These snapshots are either a standard backup, which creates a
consistent picture of the databases as of a single instant in
time; or an on-line backup (also known as a hot backup), which
creates a consistent picture of the databases as of an
unspecified instant during the period of time when the
snapshot was made. After backing up the database files you
should periodically archive the log files being created in the
environment. And I believe the question here is how often
the periodic archive should take place to establish the
best protocol for catastrophic recovery in the case of a
failure like physical hardware being destroyed, etc.
As the documentation describes, it is often helpful to think
of database archival in terms of full and incremental filesystem
backups. A snapshot is a full backup, whereas the periodic
archival of the current log files is an incremental backup.
For example, it might be reasonable to take a full snapshot
of a database environment weekly or monthly, and archive
additional log files daily. Using both the snapshot and the
log files, a catastrophic crash at any time can be recovered
to the time of the most recent log archival; a time long after
the original snapshot.
What other details can you provide about how how much activity
there is on your system with regards to log file creation
and how often a full backup is being taken, etc.
Thank,
Sandra

Quite mysteriously, my Mac is refusing to play some of my DVDs. The DVDs aren't scratched or unplayable. I tested them this weekend on someone else's multi-regional player. These DVDs most certainly did play before on this laptop (a late-2003 Titaniu
