How do we check interconnect between RAC nodes speed in Linux environment

How do we check interconnect speed between RAC nodes on Linux, I tried with ethtool eth1 , I am not able to get good information.

Either ethtool or miitool.
If you want some synthetic benchmark tool try "iperf".

How to shutdown and start agent in ODI 11g in Linux Environment

Hi Experts,
Pls any one can help me on "How to shutdown and start agent in ODI 11g in Linux Environment" and where can I find Agent.sh and Agentshutdown.sh files location in ODI 11g and parallely how can I find Odiparameter.sh file location
Thanks in Advance
Regards
Phani

Phani ,
Go to your <ODI_11g_HOME>/oracledi/agent/bin
and you will find agent.sh , agent_<standalone_agent>.sh and odiparams.sh and other agent files.
Step 1. Update your odiparams.sh
Step 2. Create the Physical and Logical Agent int your Topology using the same port_number and name provide while creating the Stand alone agent during installation ( or) create accordingly the agent in Topology with name and port number as required and make the modification in agent_<stand_alone>.sh file
Step 3. After doing so start your agent_<stand_alone>.sh
Step 4. Repeat the process 2-3 for any number of stand alone agent created on different ports and steps 1 to 3 for different Work repository
Thanks

How do you check the existance of a file in Linux?

Hi,
How do you check to see if a file in certain directory exists?
I'm trying something like.
if [ "ls fhs_jwesha_2.log" ]; then echo Here; else echo Not Here.;fibut I know that's not the right command.
Anybody?

Assuming from command line:
[user@myhost /]$ [ -f /etc/passwd ] && echo "here" || echo "not here"
here
[user@myhost /]$ [ -f /etc/no_file ] && echo "here" || echo "not here"
not hereFor a script, try:

How to disable checking for updates on Mac Silverlight for enterprise environment

Hi Guys,
We are trying to create a package for our enterprise environment to push the install of Silverlight for the Mac and have it not automatically check for updates.
What is the best way to do that?
I found the setting in the com.microsoft.silverlight.plist file that was in the user profile/library/preferences folder.
Is there a way to have this UpdateMode key set to the desired setting regardless of which user is logged onto the mac?
Thanks.
Aaron

I have zero experience of macs.
Can't you install Silverlight and the plugin for all users rather than a specific one?
I would guess/hope/expect there'd then be one plist file for everyone?

How to check interconnect load and health in RAC environments

I have setup the 2 node RAC (10.2.0.4.0) in Enterprise Linux 5.2. How can I check the load on interconnect. Interconnect NIC are not using bonding but are in full duplex mode.
Thanks
Naveed

Hi Naveed
You can control that by doing the following queries
Measure the latency of the interconnect:
set numwidth 20
column "AVG CR BLOCK RECEIVE TIME (ms)" format 9999999.9
select
b1.inst_id,
b2.value "GCS CR BLOCKS RECEIVED",
b1.value "GCS CR BLOCK RECEIVE TIME",
((b1.value/b2.value) * 10) "AVG CR BLOCK RECEIVE TIME (ms)"
from gv$sysstat b1,
gv$sysstat b2
where b1.name='gc cr block receive time'
and b2.name='gc cr blocks received'
and b1.inst_id=b2.inst_id;
Your latency should be lower than 16ms
The load btw the instances;
set pagesize 60 space 2 numwidth 8 linesize 132 verify off feedback off
column service_name format a20 truncated heading 'Service'
column instance_name heading 'Instance' format a10
column service_time heading 'Service Time|mSec/Call' format 999999999
select service_name,
instance_name,
elapsedpercall service_time,
cpupercall cpu_time,
dbtimepercall db_time,
callspersec throughput
from gv$instance gvi,
gv$active_services gvas,
gv$servicemetric gvsm
where gvas.inst_id=gvsm.inst_id
and gvas.name_hash=gvsm.service_name_hash
and gvi.inst_id=gvsm.inst_id
and gvsm.group_id=10
order by
service_name,
gvi.inst_id;

How to establish user equvalance between 2 rac nodes on non default ports??

RBHi RB ,
22 is default port for ssh. For configuring

For non default port , first of all you need to configure ssh on new port . For that refer :

Rac node failed how do you bring it back up?

Example: If there are 3 RAC nodes and one becomes unavailable/fails, how do you bring it back up?

There are typically two basic reasons why a RAC node will go down.
A cluster issue, causing the node to be evicted. This usually means the node lost access to the cluster storage (e.g. no access to voting disks), or lost access to the Interconnect.
An o/s issue causing the node to fail. E.g. a kernel panic due to a page swap and memory not syncing, or a soft CPU lockup, etc.
You need to determine why it went down, and determine what is needed to enable it to join the successfully cluster again.

Private Interconnect: Should any nodes other than RAC nodes have one?

The contractors that set up our four-node production 10g RAC (and a standalone development server) also assigned private interconnect addresses to 2 Apache/ApEx servers and a standalone development database server.
There are service names in the tnsnames.ora on all servers in our infrastructure referencing these private interconnects- even the non-rac member servers. The nics on these servers are not bound for failover with the nics bound to the public/VIP addresses. These nics are isolated on their own switch.
Could this configuration be related to lost heartbeats or voting disk errors? We experience rac node expulsions and even arbitrary bounces (reboots!) of all the rac nodes.

I do not have access to the contractors. . . .can only look at what they have left behind and try to figure out their intention. . .
I am reading the Ault/Tumha book Oracle 10g Grid and Real Application Clusters and looking through our own settings and config files and learning srvctl and crsctl commands from their examples. Also googling and OTN searching through the library full of documentation. . .
I still have yet to figure out if the private interconnect spoken about so frequently in cluster configuration documents are the binding to the set of node.vip address specifications in the tnsnames.ora (bound the the first eth adaptor along with the public ip addresses for the nodes) or the binding on the second eth adaptor to the node.prv addresses not found in the local pfile, in the tnsnames.ora, or the listener.ora (but found at the operating system level in the ifconfig). If the node.prv addresses are not the private interconnect then can anyone tell me that they are for?

How to execute DBMS_JOB at exactly one RAC node

Hello,
after unsuccessfully searching for "RAC" and "DBMS_JOB" I open this thread.
Can you tell me how to dedicate one RAC-node for doing my batch-jobs
which are started by using dbms_job (so there is no tnsnames.ora which is used).
Thanks in advance

hi,
Let's say the instances are named:I1, I2, I3, I4
Issue:ALTER SYSTEM SET JOB_QUEUE_PROCESSES=0 SCOPE=BOTH SID='I1';
ALTER SYSTEM SET JOB_QUEUE_PROCESSES=0 SCOPE=BOTH SID='I2';
ALTER SYSTEM SET JOB_QUEUE_PROCESSES=0 SCOPE=BOTH SID='I3';
ALTER SYSTEM SET JOB_QUEUE_PROCESSES=10 SCOPE=BOTH SID='I4';So that only instance I4 will run jobs.

Yoann.

How to make interconnection between a legacy system and SAP system?

Hi Group,
I have a query on the interconnectivity between a legacy system( non-SAP ) and an SAP system.
The legacy provides data in the form of Files only.
my queries are as under:
1)
how can I make a connection to the Legacy from my SAP system?
2)
what are the different ways by which I can connect these 2 different systems?
3)
I hope there might be a chance of connecting the systems by way of using webservices, in this case what are the things I need to follow inorder to make the connection and get the data from legacy?
please provide me with necessary info on these queries to proceed further.
thanks in advance.
Regards,
Vishnu.

Hi,
U can use the GUI function m modules to fetch the data from legacy systems.
Also With the help of Remote FMs u can get connected to the SAP backgrounds from NON SAP background like Portal.XI is an interfacing tool used to connect 2 SAP or SAP to non SAP medium.

Ajit.

How to get dbms_scheduler to run jobs on different RAC nodes

lets say I have 3 jobs and I want to run each on different RAC nodes. How do I do this?

Hi,
Pierre's response shows the easiest way to do this on 10g (create a service for each instance, then a job class for each service, then assign jobs to specific job classes).
In 11g there is a more direct method, you can just set the INSTANCE_ID attribute of a job using dbms_scheduler.set_attribute.
Note that for PL/SQL jobs Oracle recommends using services instead of instance ids because they provide better availability if one instance goes down or has to be taken down.
Hope this helps,
Ravi.

Automation adjustments between 2 nodes...How?

Hi,
I'm trying to lower or increase volume on a track with automation on a selection between 2 nodes by just moving the line in-between the 2 nodes.
seemingly a simple task but, I don't seem to know what command to use in order to achieve this.
Can someone help me out
Thanks

This sometimes happens when you're resolution of the Arrange is too small so get a bigger picture of the area you're working at and it should work fine. I use it every day so I know it works fine. Also your mouse handling could be the problem - just drag the middle line down vertically without moving to the right or left otherwise you will overwrite the outer nodes like you have experienced.
