Snapshot Schedule

Hey,
I have created several snapshots with 'Start With' set to sysdate and next set to sysdate + 1 and I was just wondering what would happen if for some reason the materialized wasn't updated on a particular day, would the schedule resume with the update the following day or would the schedule need to be set again?
I am asking this because it seems some of my views are not being updated on the schedule I initially created them with and I am trying to find out why.
Thanks

Hi,
i already had this case
It seems that you have not to set again the schedule, he resumed himself to the next schedule.
Cheers

How to enable snapshot-schedule in Soalris 10

Hi,
I have installed Solaris 10 with ZFS as root file system.
In the same ref. I would like to enable the automatic snapshot schedule rpool.
While checking I found GUI option only to do the same, can any one help me out to enable the above option with command line.
Thanks in advance.
Note: I do not have GUI access of the server.
Thanks
Rajan

Hi,
What about using cron?
To snapshot everyday at 19:00 all zfs under zones_pool, we just add these lines in crontab:
00 19 * * 1 /usr/sbin/zfs destroy -r zones_pool@monday_19:00;/usr/sbin/zfs snapshot -r zones_pool@monday_19:00
00 19 * * 2 /usr/sbin/zfs destroy -r zones_pool@tuesday_19:00;/usr/sbin/zfs snapshot -r zones_pool@tuesday_19:00
00 19 * * 3 /usr/sbin/zfs destroy -r zones_pool@wednesday_19:00;/usr/sbin/zfs snapshot -r zones_pool@wednesday_19:00
00 19 * * 4 /usr/sbin/zfs destroy -r zones_pool@thursday_19:00;/usr/sbin/zfs snapshot -r zones_pool@thursday_19:00
00 19 * * 5 /usr/sbin/zfs destroy -r zones_pool@friday_19:00;/usr/sbin/zfs snapshot -r zones_pool@friday_19:00

Snapshot refresh DBMS Jobs

Hello,
I have a snapshot scheduled to refresh every hour. I have noticed that job is actually not running every hour. Here is an example of what i am trying to explain.
DECLARE
X NUMBER;
BEGIN
SYS.DBMS_JOB.SUBMIT
( job => X
,what => 'dbms_refresh.refresh(''"Schema"."FLODS_RENEW_MV"'');'
,next_date => TO_DATE('08/08/2006 09:22:00','dd/mm/yyyy hh24:mi:ss')
,INTERVAL => 'SYSDATE+1/24 '
,no_parse => TRUE
SYS.DBMS_OUTPUT.PUT_LINE('Job Number is: ' || TO_CHAR(x));
END;
COMMIT;
This runs approximately for 3 mins. And i noticed today that the next_date changed the time to next_date => TO_DATE('08/08/2006 10:25:00','dd/mm/yyyy hh24:mi:ss').
So, is there any way to schedule a job every hour? Insted of every hour after the job finished executing?
Thanks

Hi,
This is one of the good reasons for using dbms_scheduler instead of dbms_job. dbms_scheduler supports a calendar syntax (actually a modified iCal RFC 2445 standard) for scheduling at regular intervals. The following job skeleton runs every hour at 22 mins after the hour starting immediately
begin
dbms_scheduler.create_job(
job_name=>'my_hourly_job',
job_type=>'plsql_block',
job_action=>'my_proc();',
repeat_interval=>'freq=hourly;byminute=22;bysecond=0',
enabled=>true , auto_drop=>true
end;
This is much clearer than using an ugly PL/SQL time function with TRUNC . It also deals automatically with daylight savings time switchovers which is uncertain with the PL/SQL time function.
With the new calendar syntax there should really be no reason to revert to time functions.
Hope this helps,
Ravi.

Do we need Snapshots on our aggregates?

Dear mates, our question is very simple.We have two Storage Processors on a FAS2240-4 Chassis that are replicating volumes (Through SnapMirror technology) to another FAS2240 Chassis on a remote/different DataCenter.We do NOT replicate the whole aggregates that contain these volumes and we will NOT need to revert an entire aggregate to a previous state.In this scenario, is it needed/advisable to have:- The aggregate snapshots scheduling active ?> snap sched -AAggregate aggr0: 0 1 4@9,14,19Aggregate aggr1: 0 1 4@9,14,19- The 5% aggregate snapshot reserve?netapp2-spa> aggr options aggr0...... percent_snapshot_space=5%, May we disable scheduling and set percent_snapshot_space=0%?Thank you so much in advance

That's the default out of the box configuration.In my case, I do snap sched -A aggr0 0 immediately and remote any snaps that might be there.I don't see a reason why you need aggregate snapshots in your caseAlso, another way to check your aggrs reserve issnap reserve -A From: severino santirso fernandez <[email protected]>To: Josh Goldfarb <[email protected]>, Date: 04/22/2014 12:25 PMSubject: - Do we need Snapshots on our aggregates?Do we need Snapshots on our aggregates? created by severino santirso fernandez in Data ONTAP 7G/8.x 7-Mode - View the full discussion Dear mates, our question is very simple.We have two Storage Processors on a FAS2240-4 Chassis that are replicating volumes (Through SnapMirror technology) to another FAS2240 Chassis on a remote/different DataCenter.We do NOT replicate the whole aggregates that contain these volumes and we will NOT need to revert an entire aggregate to a previous state.In this scenario, is it needed/advisable to have: - The aggregate snapshots scheduling active ?snap sched -AAggregate aggr0: 0 1 4@9,14,19Aggregate aggr1: 0 1 4@9,14,19 - The 5% aggregate snapshot reserve?netapp2-spa> aggr options aggr0...... percent_snapshot_space=5%, May we disable scheduling and set percent_snapshot_space=0%?

Subscriptions in Database but not showing in SSRS report

Hi,
I recently migrated our primary SQL server to a new server. Everything has been working without issue and SSRS has also been working without issue.
However I now see that the subscriptions that were created have disappeared from SSRS. However they are visible in the Report Server database subscriptions table.
Is there any reason that I cannot see them in SSRS? How do I get these back? I am an admin and have full rights but cannot view them.
Thanks

Hi JordanWebbBoxit,
In SQL Server Reporting Services (SSRS) migration, we can move the report server databases that are used in a current installation to a SQL Server Database Engine instance that is on a different computer. Both the ReportServer and ReportServerTempdb databases
must be moved or copied together. Subscriptions, cached reports, and snapshots are preserved in the moved database.
However, we must re-create role assignments, subscriptions, shared schedules, report snapshot schedules, custom properties that we set on reports or other items, model item security, and properties that we set on the report server.
There is a tool (Reporting Services Migration Tool) that migrates reports and other artifacts from one report server to another report server. It can also be used as a backup and restore tool for Reporting Services. You can down load from following link:

Automate statspack report generation.

Hi All,
I have a 9i db on HP-UX. It has statspack snapshot scheduled at every 10 mins.
Is it possible to generate and mail the stats report automatically for a perticular period ? Is there any standard job or Shell script is to be used.
Thanks in advance,

First thing 9i is loong time back got desupported. Please use a supported release at the moment. Second, AFAIK there is no such mechanism available by default to do so. Since you are in 9i and the only scheduling package in that was dbms_job, even writing a custom code to do so would not be a very trivial task.

How do you troubleshoot a scheduled snapshot

Hello, I have a ton of reports that have a snapshot taken on the 2nd day of the month. Has worked fine until this past weekend when the snapshots did not happen. There is nothing I see in SSRS that explains it. The schedule is still there. Is there a way
to find the root cause of why the snapshots didn't fire? The server and database were functioning at the time.

Hi cmunkres,
As JJordheim posted earlier, please check if the schedule is work well in the report server. In SSRS, we can open the Schedule table in the ReportServer database to check the schedule. And the SnapshotData table is record the data about the snapshot.
Reference: Report Server Database
Alternatively, we can check the log file to fine the root case. In SSRS 2012, the log file default location is:
C:\Program Files\Microsoft SQL Server\MSRS11.MSSQLSERVER\Reporting Services\LogFiles
Could you please post the error log? It is benefit for us to do further analysis.
Hope this helps.

Schedule Snapshots Rotation

Hello,
I have two Hyper-V servers running Replica feature, it is working great, but it only protects me from hardware failure.
Now I want to have snapshots enabled for quick rollbacks (and full backups for more restoring options, but that's for later).
I found this script which describes how to schedule a snapshot each 7 days: https://support.managed.com/kb/a1872/how-to-automatically-rotate-hyperv-snapshots.aspx
From what I understand, it will rotate the Snapshot each 7 days, creating a new one and deleting the previous... but I am looking for something more complicated.
What I really wanted was having a snapshot each 7 days, just like that example, but keeping the last two weeks, and also have a new snapshot daily. So I would always have three separate snapshots instances (2 weeks old, 1 week old and "yesterday").
If I notice performance degradation, I will only keep 2 snapshots (1 week and 1 day old).
Does anyone know how to do it?
Thanks,
Rafael

Hi Brian,
Thank you very much for your answer.
Well, I am not thinking of snapshots as a backup. I am thinking about a fast way to do a rollback in case of need.
Recently I had a problem with a server where the last backup I had was 5 days before, and recover was not very fast (very fast I mean a few minutes, if that much). Snapshots are a way to cover me from that kind of problem.
Because of the quantity of servers I run, most of them have automatic updates. I had a case not long ago that one update messed up the "fonts" on a windows server 2003. I also have some servers where more then one people have access... once a employee
deleted by accident something he was not supposed to.
Beyond having snapshots, I will also have proper backup. Maybe having 2 weeks of snapshots is a little too much. But I think having at least one day and a week always recoverable can save me some headaches.
So... my question is how to make a script to always have a one week old and a one day old snapshot. The script I have for a week is:
$Days = 7 #change this value to determine the number of days to rotate.
$VMs = Get-VM
foreach($VM in $VMs){
$Snapshots = Get-VMSnapshot $VM
foreach($Snapshot in $Snapshots){
if ($snapshot.CreationTime.AddDays($Days) -lt (get-date)){
Remove-VMSnapshot $Snapshot
Checkpoint-VM $VM
How to add a daily snapshot without overwriting the weekly snapshots?

Analytical snapshots and scheduled jobs

Hello,
for extended analytical reports we need to make the snapshots of our statistic datas every day.
There is an option of doing snapshots of the Project in Project Management, but we need to have snapshots of our own BO's or data sources. Is there any possibility to do this?
In case snapshots can't be done by the system we also would perform it in coding, by creating business objects with required datas and saving them. But we need to do the saving automatically (regularly).
In Project Management it is also possible to run scheduled snapshots. How can we schedule jobs (it would be enough if we could execute an action which saves our datas at scheduled time)?
We have found only "Mass Data Run Process" in this context but the MDR's can be done only for the special standard Floorplans, aren't they?
Best regards,
Leonid Granatstein.

Hi,
currently it is not possible to create snapshots for partner BO content by a standard process.
Also defining a mass data run object, which you could schedule and where you could implement the snapshot by yourself, is not available for partners yet. So we have no standard mechanism available to get your task done with the use of the current implementation possibilities.
The only option I see is that you develop the snapshot activity on your own in ByD studio.
To trigger the snapshot activity on a regular basis, I only see the option to trigger this from outside. An option would be to define a web service or an XML file upload.
You could write for example a small program ( by using PHP or .NET) on a PC which runs on a regular basis and which uploads an XML file or calls a web service. This then triggers the snapshot activity you have programmed in ByD Studio.
I hope this helps.

Thomas

I need to schedule the refreshes every day except Saturday and Sunday. Got any idea how can I do that?
Prash

You would probably want to use the dbms_job package to schedule the refresh in that case, rather than scheduling the refresh in the materialized view creation. Write a function that returns the next refresh time for your snapshot and pass that in when you create your job.

ISCSI Target Scheduled Snapshots

I know there are cmdlets to snapshot a target but is there a built in way to schedule snapshots?
Alternatively, is there a cmdlet to list snapshots for a target so I can create a script to run on a schedule to remove old snapshots and create new ones.

Yes, you can use Schedule Snapshot Wizard to have automatic snapshots. See:

http://technet.microsoft.com/en-us/library/gg232610(v=ws.10).aspx
Alternatively you can use cmdlets to deal with these tasks (PowerShell would give you more control over
creation / deletion of a snapshots. See:
iSCSI Target Cmdlets in Windows PowerShell
http://technet.microsoft.com/en-us/library/jj612803.aspx
The ones should be of your interest are Checkpoint-IscsiVirtualDisk and Remove-IscsiVirtualDiskSnapshot cmdlets.
Also you may use SMI-S and WMI if you want to use say C# or C++ and not PowerShell.
Some more of the cmdlets use links (including samples). See:

Error while scheduling through web service

We have created Web service through WSDL of OBI Publisher. Also we created a web service proxy client to call the services offered by OBI Publisher. We actually want to "Automate the Scheduling of Reports" according to our requirement:
1. We used to schedule the reports manually by giving the parameters(used to populate data in reports) and other fields like select report name, report destination, format of reports ( .pdf, .docx,etc) through Oracle BI Publisher.
2. As there are thousands of permutations of report input parameters possible, so it is difficult to schedule them manually.
3.We also want to schedule report to a particular folder according to some parameter, for the ease of the user visibility.
Above requirements are not currently available with Oracle BI Publisher.
We are getting error while scheduling through ScheduleRequest class.
The client.java is as follows:
public class ScheduleServiceClient
@WebServiceRef
private static ScheduleService_Service scheduleService_Service;
public static void main(String [] args)
    scheduleService_Service = new ScheduleService_Service();
    ScheduleService scheduleService = scheduleService_Service.getScheduleService();

One read_only snapshot can not be refreshed?

Hi,
I have created a read_only snapshot in the snapshot site(Oracle 8.1.6). The master table is a view table in the master site( Oracle 7.3.4).The master site has install the replication option and the snapshot site doesn't install the replication option.
Here is my script to create snapshot in snapshot site:
CREATE SNAPSHOT testing
TABLESPACE hyper_d01
STORAGE (INITIAL 32K NEXT 32K)
REFRESH NEXT sysdate + 1
WITH ROWID
AS SELECT *
from testing@mastersite;
/****end **/
The snapshot has been created successfully.
I found this snapshot doesn't refresh everyday after I created it. It doesn't change after I created it.
I can manually refresh it by running this command in snapshot site:
execute dbms_snapshot.refresh('testing');
It did complete refresh and It worked.
I am confused...
Could anyone tell me what could cause the scheduled refresh fail?
-Do I need to ask DBA to give me special privillage to do automaticlally refresh?
-Does the difference between Oracel 7 and Oracle 8 cause the scheduled refresh fail?
One more question:
Does Oracel 7.3.4 support primary key type snapshot?
I tried to create the primary key type snapshot in Oracle 8.3.4 for the master table in oracle 7.3.4, I got error message.
Thanks in advanced,
Helena Wang

How did you create the database link?
We were testing it here, and when we had created the database
link using the syntax "create database link mastersite using
'mastersite';", it doesn't work.
It only works when the database link is created using the syntax
"create database link mastersite connect to user identified by
password using 'mastersite';"
The person that realized it was one of the DBAs that works with us.
I hope it helps you.
