I know that the best things how to deal with split-brains is to avoid them. I have a traditional 1 x 3 replication set up. I am looking for an indicator (except of gluster logs) that tells that a split brain or any other type of error occurred. This then could trigger some other actions from my side, nevertheless, I can't sit and look into logs all day long waiting for an error there. Is there anything in gluster that would tell me that "something wrong has happened, take a look into logs" or "take some action" ?
Thanks for any hints in advance,
Peter
For determining split-brains there is a command "gluster volume heal info split-brain". This will list all the files which are in split-brain state. With this there is no need of monitoring split-brains in log messages.
Or You can use syslog/rsyslog to receive mails in case of split-brain event . Refer to : http://www.techrepublic.com/article/configure-it-quick-log-linux-system-events-with-syslog/ or https://www.dalemacartney.com/2012/08/19/configuring-syslog-in-red-hat-enterprise-linux-6/
Check out this gluster plugin for Nagios.
It will tell you about the healing status. Split-brain is a particular case of file that is not getting healed properly.
This link explains how to configure the glusterfs plugin using nagios :

All my datasheets, tables, and ALL items inside BQ are un EU. When I try to do a View->to->Table 15 min scheduled query I get an error regarding my location, which is incorrect, because all, source and destiny are both on EU...
Anyone knows why?
There is a transient known issue matching your situation, GCP support team needs more time for troubleshooting. There may be a potential issue in the UI. I would ask you to try the following steps:
Firstly, try to make the same operation in Chrome's incognito mode.
Another possible workaround is trying to follow this official guide using a different approach than the UI (CLI for instance).
I hope it helps.
In our current production system, we have several files that will be processed by Hybris hotfolder from external system on a daily / hourly basis. What is the best way to check the status of each file that is being processed by hot folder? Is there any OOTB dashboard functionality available for hotfolder? or is it a custom development?
So far, I'm following to check see backoffice cronjob logs. But it is very cumbersome process - by monitoring logs, finding out unique cron job id etc..any other best approaches?
I'm looking something similar to jenkins jobs status.
Appreciate your inputs.
There is a workaround. Please check this link :
https://help.sap.com/viewer/d0224eca81e249cb821f2cdf45a82ace/1808/en-US/b8004ccfcbc048faa9558ae40ea7b188.html?q=CronJobProgressTracker
Firstly, you need to implement the CronJobProgressTracker class to your current cronjob. And you can see the progress of cronjob in either hac or Backoffice ;
hac : execute flexible search
Backoffice : you can add a setting for the CronJobHistory menu. Then
just click the refresh button to see the last state of progress.
As I know , not possible to track file progress state in OOTB hotfolder. Also you can write custom code in your uploading process .BTW , to be honest my last sentence is not so meaningful . Because need to know your hotfolder xml context to give more hints ..
Hot-folder ingests a file in a series of steps specified by the beans in the hot-folder-spring.xml.Add loggers in each of the bean, eg- batchFilesHeader, batchExternalTaxConverterMapping
Then you can see the status in the console logs.
Is it possible to replay all failed messages through nServiceBus without using ServiceControl/ServicePulse?
I'm using NServiceBus.Host.exe to host our endpoints. Our ServiceControl/ServicePulse database became corrupt. I was able to recreate it, but now I a few failed messages in our SQL database which are not visible through the ServicePulse.
Will this help?
Take a look at the readme.md
For people who want the functionality that this tool previously
provided please take one of the following actions
Return to source queue via either ServiceInsight or ServicePulse.
Return to source queue using custom scripting or code. This has the
added benefit enabling possible performance and usability
optimizations since, as the business owner, you have more context as
to how your error queue should be managed. For example using this
approach it is trivial for you to choose to batch multiple sends
inside the same Transaction. Manually return to source queue via any
of the MSMQ management tools. If you still want to use
MsmqReturnToSourceQueue.exe feel free to use the code inside this
repository to compile a copy.
You can look at the link provided to build your own script (to mach SQL) and trip the error message wrapper so you can push the stripped message back to the SQL queue.
Does this help?
If not please contact support at particular dot net and we will be glad to help :-)
There is nothing built into the Particular stack that I know of that will take care of this.
When I have ran into issues like this before I will usually setup a console application to send some commands into the endpoint and then setup a custom handler in the endpoint to fix the data inconsistencies. This allows you to test the "fix" in a dev/uat environment and then you have an automated solution for production to fix the problem.
I need to lock a single file in AccuRev to avoid modification in the file by anyone. I know there is one way is to achieve it through AccuRev trigger. But I can't go with trigger because of the following:
1) Our AccuRev is on client side and used by many teams and therefore can't ask for server level trigger.
2) For client level trigger I need to ask put the script on all client machines or at some shared location.
Is there any other ways to achieve this easily in AccuRev?
Thanks in Advance.
Yes, Element-Level Security (EACLs)
Look in the admin manual under section "Element-Level Security (EACLs)".

I had installed Oracle 11g on windows 07,everything was working fine.But today it is giving me an error saaying ORA-01033: ORACLE initialization or shutdown in progress . I followed the steps mentioned in the different communities but unable to solve the error. After connecting as sqlplus sys/sys as sysdba. and executing below statement,i got following error. How to solve this error?
SQL> recover database;
ORA-00283: recovery session canceled due to errors
ORA-01110: data file 9: 'C:\APP\MKHATAL\ORADATA\ORCL\VELODBDATA.DBF'
ORA-01157: cannot identify/lock data file 9 - see DBWR trace file
ORA-01110: data file 9: 'C:\APP\MKHATAL\ORADATA\ORCL\VELODBDATA.DBF'
Thanks in advance!!
First, check your ALERT.LOG file typically located in D:\app\oracle\diag\rdbms\DBNAME\SID\trace\.
The latest entries in your ALERT.LOG should give you an indication on what is going on. Is the database starting? Shutting down?
Should the database be stuck in the shutdown process, you can try to kill the oracle.exe process and then restart the database via Windows Service.
Often, when the database seems to hang on startup, it is actually applying REDO to get a consistent state, so pay close attention on what the ALERT.LOG tells you.
There's more info needed to be able to solve similar issues. Questions like these are interesting to get answered:
To what level can you start the database ? None, nomount, mount or
open (exclude the last one in this case)
What does the ALERT.LOG file show ? This from the moment the first
issue is suspected to be around
An obvious question is just : what happened ? What action were you
doing when you saw the first error message ?
Can you shutdown the database ? If yes, which methods : normal,
immediate or abort only ? Know that stopping the database with ABORT
option may make problems bigger as they are already.
Did you try rebooting the server ? This is particularly an issue on
Windows, which is your case.
Depending on how you stopped the database, do you have a cold backup
?
Depending on RMAN still working : can you take a backup ? The RECOVERY you were trying is not bad, but it could be interesting to know what is happening on OS level with that file; Is it there ? If yes, is it locked or not ? Does the OS think it's a valid file ?
