Shell script to monitor the data guard

Hi,
Can any body please provide the shell scripts to monitor the data guard in all scenarios and to get the mail when problem occurs in dataguard.
Thanks,
Mahipal

Sorry Mahi. Looks like all of the scripts i've got are for logical standbys and not physical. Have a look at the link ualual posted - easy enough to knock up a script from one or more of those data dictionary views. Just had a look on metalink and there's what looks to be a good script in note 241438.1. Its a good starting point definately.
regards,
Mark

Shell script to monitor the application health deployed on weblogic

Hi All,
Is it possible to monitor the health of a application deployed on weblogic and send a mail if it is not running. I have JasperServer reporting application deployed on weblogic. The shell script should check if the application is running, if it down a mail should be sent.
Thanks

You can use WLST to get information on the state of your deployments, for example,
the python script can be used
class DeploymentInfo:
     def __init__(self,name,target):
          self.name = name;
          self.target = target;
     def getName(self):
          return self.name;
     def getTarget(self):
          return self.target;
print 'CONNECT TO ADMIN SERVER';
connect('weblogic', 'transfer11g');
print 'OBTAINING DEPLOYMENT INFORMATION';
deploymentsInfo = [];
applications = cmo.getAppDeployments();
for application in applications:
     name = application.getName();
     target = application.getTargets()[0].getName();
     deploymentsInfo.append(DeploymentInfo(name, target));
print 'CHANGE TO DOMAIN RUNTIME ENVIRONMENT';
domainRuntime();
print 'APPLICATION LIFE CYCLE INFORMATION';
applicationRuntime = cmo.getAppRuntimeStateRuntime();
for deploymentInfo in deploymentsInfo:
     state = applicationRuntime.getCurrentState(deploymentInfo.getName(), deploymentInfo.getTarget())
     print 'Application: ' + deploymentInfo.getName() + ', State: ' + state;
     if (state != 'STATE_ACTIVE'):
          startApplication(deploymentInfo.getName());In the example above the application gets started when it is not running, you can also
send an e-mail by using the smtplib package, for example
import smtplib;
server = smtplib.SMTP('email-server-host');
server.set_debuglevel(1);
server.sendmail(fromaddress, toaddress, message);
server.quit();More information on the package smtplib can be found here:

Help on preparing shell script for setting the listener password

Hi All,
I am working on checking all my DB servers listeners and if the password is not set for the listener then I need to set the password for that.
As we have many servers, I am planning to prepare the shell script for doing this task.
I am familiar with setting up the listener password manually, but strucked up to prepare the shell script to do the same task.
Can any one kindly help me on this.
Thanks in advance,

DG broker is the way to go. There are only minor points you can't control - like when you have standby redo logs and no redo application delay, dg broker will always start real-time apply.
Also, DG broker is the only way if you want fast-start failover (10gR2 feature).
What is the latency of your nework, especially under load? Add this latency to each commit - will the commit time be acceptable? If not, you cannot use sync.
What version do you use? In 10gR1, there are issues with async - there is only about 50MB buffer, and if you get such backlog, even with async commit will wait for standby. (In 10gR2 this is solved, async will read from disk redo logs.)
NET_TIMEOUT - set it low for sync (so commits won't hang long), higher for async. Default is 180 seconds, Oracle recommends minimum value to 10 seconds. I would start with 10 sec for sync, 180 for sync. The main question is, how reliable your network is, and how long brownouts you want to survive without affecting data protection (with the expense of performance).
Regarding the proper setting of all bells and whistles of archive_log_dest_n - I had best experience with leaving it to dg broker. Just set LogXptMode property to sync/async/arch, and let dg broker set everything else (service, valid_for, affirm, retries...).
The authoritative source: http://www.oracle.com/technology/deploy/availability/htdocs/maa.htm#Publications
If you are on 10.2.0.1 - 10.2.0.3, please see metalink bug 5578157, 5587231 - if sqlnet.outbound_connection_timeout is not set, the lgwr can hang even if net_timeout is set. (Yes, real-world experience:-)

Hi,
I removed the configuration and removed the broker files from RAC primary(mvmxp2) and single instance standby(mvmxs2) and re-created back.i tried it many times but getting error "ORA-16532" .I needed to have this standby backup before i start upgrading the primary.

How can change the font in the script output and the data grid ?

How can change the font in the script output and the data grid in Sql Developer?

You can't easily unless you have the latest version (2.1.1).
If you do have this version then changing the font in the Tools/Preferences menu under the code editor/fonts section will also change the font of the data grid.
For details of changing the fonts in an earlier version then see Sue's post below.

Monitor the data change

Hello guys,
I have a little problem here. I got the data stream from the data acquisition device, and the data could be indicated on a chart. I could see the waveform on the Labview front panel, and even got the data value from the indicator. However, I need to record the data at one moment, and record another data after a small time interval. Then, I need to monitor the data change. Any good idea? Thank you!

Thank you for your reply.
I would like to monitor the data, when the data sudden drop-down, I could send a message to switch off the system. My idea is obtain a data at one moment and obtain another data after a small time interval. When the change is larger than acceptable value, I switch it off.
Could you show me more detail about single point acquisition? So appreciate!

# Example INIT.ORA file
# This file is provided by Oracle Corporation to help you customize
# your RDBMS installation for your site. Important system parameters
# are discussed, and example settings given.
# Some parameter settings are generic to any size installation.
# For parameters that require different values in different size
# installations, three scenarios have been provided: SMALL, MEDIUM
# and LARGE. Any parameter that needs to be tuned according to
# installation size will have three settings, each one commented
# according to installation size.
# Use the following table to approximate the SGA size needed for the
# three scenarious provided in this file:
# -------Installation/Database Size------
# SMALL MEDIUM LARGE
# Block 2K 4500K 6800K 17000K
# Size 4K 5500K 8800K 21000K
# To set up a database that multiple instances will be using, place
# all instance-specific parameters in one file, and then have all
# of these files point to a master file using the IFILE command.
# This way, when you change a public
# parameter, it will automatically change on all instances. This is
# necessary, since all instances must run with the same value for many
# parameters. For example, if you choose to use private rollback segments,
# these must be specified in different files, but since all gc_*
# parameters must be the same on all instances, they should be in one file.

Need Shell Script for picking the files

Hi,
    I want to write a shell script for piking the files in a sequence order (according to filename with time stamp) from the sorce FTP server ..
                 Requirement is in the source directory I'm getting files (Jain_1.xml , Jjain_2.xml, Jain_3.xml .. ect..) at present my file adapter is picking all the files at a time but i want to pick one by one... that to first i want to Jain_1.xml after finish the processing of the file then only my file adapter should pick the next file ( Jain_2.xml ) .
              so.. all the forum mates suggest me to write a shell script.. but where i have to write the s hell script. and where i have to deploy this script.... my Xi is running on UNIX ... so please sugest me the procedure ...

Hi,
Why dont you use the option EOIO in which files will be picked up in order and will be proccessed in sequence....one after another....

Shell Script- To FTP the latest file with the date stamp

I have a Solaris 10 based system, where it generate some application files (multiple) in XML format and the file name comprises of the current date.
File Format is as follows;
CX-FIL-20070624000000-2-8452536d-000133.xml
Where 20070624 repesents the curent date of the file
I want to FTP these files to another server (Solaris 10 based Sun Machine) by comparing the file name with the current date.
Please let me know how I can do this by using a shell script.

Assuming you want to ftp the files with today's datestamp, you could match the files you want like so:
CX-FIL-`/bin/date +"%Y%m%d"`*
Use that in your script to generate the file list to be transferred...

Difference between the Data Guard and Stand By

Hi,
Can any one specify the difference between the Standy and Data Guarding.
Since are the Advantages of Data Guarding over the
User Created Stand By Database.
Thanks
Pavan Kumar N

DataGuard is used to allow you to create and manage standby databases, so I'm not totally clear on your question. If you're using DataGuard, you're creating standby databases.
Are you talking about the difference between using DataGuard to manage your standby databases rather than writing your own scripts to manage your standby databases? If so, you've got cost issues-- DataGuard requires the enterprise edition, while you could write your own standby scripts using the standard edition. You've got support and testing issues-- if something goes wrong, you're on your own to debug your scripts. If you're using DataGuard, there is a variety of documentation available and a variety of options for support. Oracle has also invested quite a bit of time testing DataGuard with various failure scenarios-- it's likely that you wouldn't have that much time to test your own scripts. On a day-to-day basis, DataGuard provides integration with various monitoring utilities (i.e. Enterprise Manager) and provides a rather nice set of tables to view information about what's going on. DataGuard also provides functionality like the ability to automatically detect and resolve gaps in the archived log files that your scripts would not likely be written to handle.
And, of course, your scripts could only manage a physical standby database. DataGuard can manage both physical and logical standbys.

Monitoring failover - Data Guard Broker

Hi,
I work on a Oracle 10.2.0.4 database on Solaris 10. It is a 2 node RAC database with a physical standby configured.
I want to monitor (send a mail) to myself when failover occurs (which will be triggered by data guard broker ) , I think so I can monitor the failover using alert log (which normally does log the command when we initiate a failover) but I am not sure whether data guard broker also does the same( writes appropriate commands when a failover is triggered)
Is there any other way we can come to know when a failover occurs (we can query database_role from v$dataguard status) but I am looking for some trigger that will be fired instantaneously when a failover is initiated ?
Also is it possible to monitor the observer, whether it is up or not ?

Hi,
you have several possiblities to do that. Easiest is to use predefined Grid Control Events for it. Or you may put a trigger on the event "after DB_ROLE_CHANGE on database".
Monitoring the observer can be done with dgmgrl like
connect sys/<pw>@<cd>;
show configuration verbose;That show you the presence and location of the observer.
I give you an example for the usage of the trigger that starts a service depending on the role of the database. You may customize it to send you an email.
begin
