Failover, SO activation sequence and Log

Hi
Wud u please clarify my following doubts :-
1. Failover
If a partition carries 3 failover service objects-. A, B & C - and if service object A fails, I
believe that the whole partition in replicated and reinstantiated. If so what happens to the
non-failed objects in old partition and the newly created clones of those objects in new partition?
Which one wud be used while referenced ?
My unerstanding is that it manages failover by partition than by objects so that failed partiton is
activated on some other assigned nodes.
2. Service object activation sequence
How the activation sequence of service objects are determined ? I have a strange problem. One of my
service object (in its init method) try invoking a method on another service object; but gives
"Attempt to invoke a method on a NIL object" exception. I inserted a loop above this line as
DO WHILE thisSO = NIL THEN
END DO;
flag = thisSO.GetStatus();
Still the exception occurs. The called service object reads from a flat file to populate its data
members. Can I change the activation sequence of service objects ? Both the service objects, talked
about here, belongs to same partition and are of USER visibility type.
3. Partition Log
The partition log generated overwrites the existing file if I specify a file name name using -fl
flag at command line. Is there anyway that I can make it to append to existing log ?
ThanX.. @nthoz

Re: Failover, SO activation sequence and Log

Ok. I was dozing. I was thinking "parition" when you were saying "node". We currently have just one production box, so I don't think like that yet. :)

Hi,
The only reason I thought that Node2 should be less powerfull was that I consider that a backup box should be less powerfull (less expensive!), with less memory for instance.

We have had extensive problems with Forte's Failover scheme & our fledgling WAN. Say we have a partition with 1 SO (mostly events) replicates for failover with 2 counts.

The only thing that may make it less powerful, is if you start replicate 1 with certain memory flags, and start #2 with less memory (why, I have no idea).
So, due to our rather unstable WAN, at this point, we have stopped setting up that partition for failover. It was causing more problems, than it was helping. (unless someone can tell me how a client can suddenly switch from using #1 to #2 & I have no Events or Exceptions thrown?)
Ok. I'm done rambling & I'm going back to sleep now.

Hi,
1. Failover
As far as I know (and can imagine), on most cases you are right, because the main cause would be that your replicate (or your node) has shut down. But, the real mechanism should be a little more complex.
The fail-over should be detected with a DistributedAccessException received by the caller. So if you have Partition 1 with 2 Service Objects with some network problems : you could call Service 1 without success on replicate 1 (because of network time outs), Forte could start to give you the new reference for Service 1 on Replicate 2, then you call Service 2 with success (network is now available) on Replicate 1 because you still have the Service 2 reference on the Replicate 1 in the caller partition (you did not ask the name server a new reference). As far as I tested, it could happen : you can stop the name server, if your partition has already resolved the names (Services references), your application will still work; only new client partitions will have an error.
So, I guess that fail-over has been imagined more for Partition, node shut down. One other point : on a single node, auto-start should be more efficient because it will be dynamic and not limited to a fixed number of replicate.
An other case should not be forgotten : when you hit to Replicate 2 on Node 2, due to fail over, you can imagine that Node 2 is only a back-up node (less powerfull than Node 1). You restart the Node 1 and Replicate 1. You would like to use Replicate 1 on Node 1 then. Forte will not do the work for you. You will need to release connections from your Service Objects to resolve once more the Names from your name server. If you don't do it, new clients may use Node 1 Replicate 1 and old clients Node 2 Replicate 2 also.

No activity on smspxe.log and I am not getting very far when testing OS deployment

Hello and thanks for any help. I have a few OS deployment issues.
1. There is no activity on smspxe.log. This has been a problem for two weeks. I believe it is a symptom of trying to fix a bigger issue (#2)
2. I am trying to move us from SCE imaging to SCCM 2012. We had CM working at first but had to switch back. Now when I try to do a PXE boot, I see this message.
Recovery
Your PC needs to be repaired
The Windows Boot Configuration Data file from the PXE server does not contain a valid operating system entry. Ensure that the server has boot images installed for this architecture.
File:\Tmp\x86x64{BBD9AF6-E64E-41A9-840504118DB33B45}.bcd
Error code: 0xc0000098
I have tried these steps - disable PXE on the DP (which is also the MP), remove WDS, I hid the remote install folder, restarted server, installed the WDS role. It wouldn't start so I did wdsutil initialize. Enabled PXE. Maybe important to note; before
this the remoteinstall share was RemoteInstall. Now it is "REMINST".
I have boot images for both i386 and x64.
Thanks so much for any help.

Hi,
You could try the steps in the blogs below(I know that you have tried some steps). Please make sure the RemoteInstall folders have been populated.
Quote:
Go to the Properties of the DP and uncheck the box "Enable PXE support for clients"
Wait for a short time while Windows Deployment Services uninstalls
Reboot the DP
Re-enable PXE support and wait while WDS re-installs
WDS usually requires a reboot so you should reboot again
ConfigMgr 2012 / SCCM 2012 Task Sequence fails with BCD error
Quote:
My initial thoughts were to try and redistribute the boot images but this didn’t work for me. So I removed the PXE role from the DP in question, waited for the success message to appear under the DP monitoring and rebooted the server. After rebooting the
server I enabled the PXE role on the DP, this time leaving Unknown Computer Support enabled. I waited for the success message in the DP monitoring and rebooted the server. After the reboot I made a point of checking the status of the WDS role in Server Manager
(all was well). I also checked the RemoteInstall folder had the same contents as other working DP’s and tried again. Hey presto problem solved!

To apply license in FWSM (Active-Active mode) and disable failover

Dear Team
I want to apply license to increase security context in FWSM which is running in Active-Active mode on VSS Core switches
As per below document, first we need to disable failover by entering 'no failover' command on active FWSM and then apply the license seperately on both FWSM.
I just want to know when i will disable the failover then standby move to pseudo-standby state.
Will there be any services impact which are running behind the FWSM when disbaling the failover and then re-enabling the failover.
http://www.cisco.com/c/en/us/td/docs/security/fwsm/fwsm40/configuration/guide/fwsm_cfg/swcnfg_f.html#wp1073226
Appreciate your response.

Hi,
I think in your case as it is Active/Active , there is one extra step required.
You need to make all the contexts active on one unit and on the other one all should be standby.
Then disable the failover and update the license and re-enable the failover.
Thanks and Regards,

Problem in uploading data from psa to active data and change log dso.

hi experts
my data from psa is coming to new data dso but not to active data and change log dso. can you please help me out...

Uday,
Please select the request from Manage screen of DSO and click on Activate, pop-up comes again select the request and click on Start. ( If it is Standard DSO ).
In case of Write optimized DSO you need not to activate it.
Regards,
Ramkumar.

HT1414 I was using my IPAD this morning. Powered it down, then when I powered it back up, it said activation required.. but it would not accept my password. I hit skip and logged in fine. Is this something I should be concerned about?

Probably - if it happens again. Chalk it up to a fluke occurrence for now.
I get the message on my iPad that it can't connect to the iTunes Store - While I am in the iTunes Store or the App Store happily navigating from one tab to another.
You can try rebooting the iPad to "clear the cobwebs" but if it is OK now, I probably wouldn't be overly worried. Rebooting being holding down on the sleep and home buttons until the Apple logo appears on the screen.

Any help on creating a Generic logic would help as in future there would be Event sequences added to EVENT_NAME_SEQUENCE table

So that was an interesting problem!
I decided to go for a solution where build concatenated lists to compare these. As started to play with it, I realised that there is risk for a scaling problem, so I introduced some optimisations. And it seems that they helped me to find the final solution.
There are two CTEs. The first CTE builds a fixed-width list of the event-name ids for each sequence. I also extract the length and the first value of each sequence.
In the next CTE I find the start of all sequences in the EVENT_NAMECHANGE table. For each row where the the event is the first of a sequence I read as many rows as there are in the sequence and form a fixed-width list of event-name ids. If this list matches
the sequence list, this row is returned from the CTE, together with the count of the sequence.
In the final query, I repeat the CROSS APPLY in the second CTE, but this time without FOR XML to get the actual rows. I need DISTINCT here, since one sequence may include another.
It is of course impossible to test performance without knowledge of the actual table. But is my assumption that EVENT_NAMES and EVENT_NAME_SEQUENCE are fairly small table, whereas EVENT_NAMECHANGE is big, maybe 100 millions of rows. Obviously the table has
to be scanned once, but I think performance should be proportional to the number of rows in the table times the length of the longest sequence.
Here is my complete test script.

Logging Alarm Activations, deactivations, and Acknowledgments

Lookout 5.1
I have a need to be able to execute an event on alarm events when they become active, inactive, and are acknowledged. Management wants an up to date record of when an alarm comes in, how long that alarm is on, how long it takes operations personnel to respond to the alarm, etc... I see that I can use the $Alarm block to produce a list of when the alarm is activated, but don't see any method of allowing me to capture when that alarm goes inactive, or when the alarm is acknowledged.
Does such a capability exist, or is management stuck yet again?
David

David,
There is not an easy way to access the alarm database. Alarms are stored in the MSDE database, and you are free to try to access this database via OBDC (in a 3rd party environment or from Lookout) but the tables aren't published and it is not a supported method of accessing alarm information. Oh, you are using Lookout 5.1 which stores alarms in the Citadel db. In any case, you could try using OBDC to import alarms into a datatable. This may be easier than in Lookout 6.0 but I don't know the structure of the tables -- you'd be on your own there. Here are a few other ideas:
Have you used the ActiveX AlarmBrowser object? This embeds the same Alarm Browser you use in MAX right into your Lookout Panel. This gives you all the information you are asking for (timestamp for when the alarm occured, when it was acknowledged, when it became inactive) and color codes the four alarm states: active unacknowleged, active acknowledged, inactive acknowledged, and inactive unacknowledged. Now, it just presents the timestamps, not a running amount of time the alarms have been active, etc, and you can't really do anything besides acknowledge the alarms from it, but it does present the information you are referring to.
If you actually want to programmatically do things with alarms, you can use either the $alarm object built into every process, or create your own Alarm objects. Alarm objects have an 'active' datamember that you could work with to create different types of timers with. As far as knowing when individual alarms are acknowledged programmatically, the only thing I can think of would be to create a separate alarm area for each alarm, then you can use the $alarm object and check which alarms are active and/or acknowledged. With some creative uses of timer objects, the $alarm object, and expressions, you may be able to do what you are thinking about. Hope this helps!

Open database if an active online redo log is missing

Hi,
Sorry for the rather long post, but I specified all the steps I performed and couldn't make it shorter :-(
I need an advice on how to open the database if an active online redo log is missing.
For test purposes I intentionally performed a shutdown abort when the redo log group 1 was in active state and then renamed its only member (REDO01.LOG) so that the database couldn't perform crash recovery using it. Then upon startup I obviously got the message:
ORA-00313: open failed for members of log group 1 of thread 1
ORA-00312: online log 1 thread 1: 'H:\ORADATA\TESTDB\REDO01.LOG'
ORA-27041: unable to open file
OSD-04002: unable to open file
O/S-Error: (OS 2) The system cannot find the file specified.Ok, so I checked the state of the logs:
{noformat}
SQL>SELECT a.GROUP#, first_change#, SEQUENCE#, a.status, SUBSTR(b.MEMBER, 1, 40) MEMBER, b.status mem_status, a.archived
2    FROM v$log a, v$logfile b
3   WHERE a.GROUP# = b.GROUP#
4 ORDER BY a.GROUP#, b.MEMBER;
GROUP# FIRST_CHANGE# SEQUENCE# STATUS           MEMBER                         MEM_STA ARC
     1        592134         29 ACTIVE           H:\ORADATA\TESTDB\REDO01.LOG           YES
     2        592268         30 CURRENT          C:\ORADATA\TESTDB\REDO02.LOG           NO

{noformat}Since opening the database to perform a log switch and thus change the status of the redo log group 1 from ACTIVE to INACTIVE to recreate the member isn't possible, I performed database recovery.

Log applied.
Media recovery complete.
SQL>So for log sequence #28 I accepted the proposed archived redo log in the FRA, for sequence #29 (that's the online redo log that is missing!) I manually specified its archived copy, and for sequence #30 I specified the CURRENT online redo log. And as it seems the media recovery was successful.
Next I tried to open the database but again got the error:
SQL>alter database open noresetlogs;
alter database open noresetlogs
ERROR at line 1:
ORA-00313: open failed for members of log group 1 of thread 1

O/S-Error: (OS 2) The system cannot find the file specified.
The status of the log groups and its members is exactly as it was in the first query I wrote above, i.e. the redo log group 1 is still ACTIVE, so it's needed for crash recovery (which I had already done manually if I understand correctly how Oracle works!). I also checked if the datafiles are inconsistent (described in metalink doc id 1015544.102):
SQL>SELECT DISTINCT CHECKPOINT_CHANGE#, FUZZY FROM V$DATAFILE_HEADER;
CHECKPOINT_CHANGE# FUZ
            592269 NOSo, everything seems ok as far as datafile consistency is concerned.
My question is: how can I rename/drop/clear/whatever the member of redo log group 1 to open the database?
I tried to rename the log file member, to add another member to it, to open the database with resetlogs, to clear the logfile group 1, but all without success:
1)
SQL>alter database clear logfile group 1;
alter database clear logfile group 1

You could check if the recovery was complete by (re)creating the controlfile with the resetlogs option.
<CREATE CONTROLFILE REUSE DATABASE define_db_name RESETLOGS NOARCHIVELOG
...>Thanks for the hint. If possible, could you only check if the steps I'm going to perform are ok.
I did an "alter database backup controlfile to trace;" and then extracted the create controlfile definition part. So in essence I should run the following statements:
CREATE CONTROLFILE REUSE DATABASE "TESTDB" RESETLOGS ARCHIVELOG
    MAXLOGFILES 16
    MAXLOGMEMBERS 3
    MAXDATAFILES 100
    MAXINSTANCES 8
    MAXLOGHISTORY 292

CHARACTER SET EE8MSWIN1250
ALTER DATABASE OPEN RESETLOGS;
ALTER TABLESPACE TEMP ADD TEMPFILE 'C:\ORACLE\PRODUCT\10.2.0\ORADATA\TESTDB\TEMP01.DBF' REUSE;Is that correct?
About the RMAN backups: Wouldn't a 'CATALOG RECOVERY AREA' populate the controlfile with backup information again (I'm not using a recovery catalog in this case)?
Thanks for the help!

Failover exec active write mem

Hi Everyone,
I was doing config change on firewall in multicontext mode.
IT has 2 contexts admin and X.
I log into admin context via ASDM and switch to context X with the ASDM as need to make changes to context firewall X.
When i config the changes via asdm and click on apply it show me message
failover exec active write mem followed by ACL which i was going to apply.
Need to confirm if above command is safe to run on production network without causing any issues?
Finally i logged into Context X which was admin for that and made the chnages via CLI.

hi mahesh,
i'm suspecting you're making changes in context x from the standby unit. you could verify with show failover command.
it's safe to assume to issue a failover exec active write mem since you're just saving the config for the active unit.
you could alternatively use the write memory all command to save the system and all context config changes.

What is the correct way to use Version Information from the sequence and from the deployment tool

I seem to be missing something in how the various version numbers are supposed to be used. My end goal is to log and possibly display in the UI the version of the sequence and which installer version was used to inspect a UUT. I have gotten most of the way there using:
How Can I Programmatically Query the Sequence File Version of My TestStand Sequence?
and logging this into the report with a function which contains:
Parameters.UUT.AdditionalData.SetValString("Test Version",1,RunState.SequenceFile.Data.Version),
Parameters.UUT.AdditionalData.SetFlags("",0,PropFlags_IncludeInReport)
The "Deployment Version" in the TestStand Deployment Utility auto incrementing the 3rd position of a version number while the sequence auto increment is working on the 4th.
My first question is are these 2 version numbers in anyway supposed to be related to each other? As it seems to me you would want those 2 reversed, I can make several installers based on sequence version X, making changes to what supporting files are also installed.
If they are not related as I suspect that they are not. How do I programatically grabed the installer version and also log that into the result report?
is there an option to perform a custom deployment build step to log the deployment version before it builds and then reference that log at runtime of the test?

Hi,
The sequence file version and deployment versions are not related.
You can build the installer with whatever version you want using the command line :

I purchased a used 2008 iMac. And although the previous owner said he deleted all of his information his iCloud account is still the primary. I don't have a clue about what to do about it. I signed him out and logged in with my info, but still no go.

I purchased a used 2008 iMac. And although the previous owner said he deleted all of his information, his iCloud account is still the primary. I don't have a clue about what to do about it. I signed him out and logged in with my info, but still no go. Is there any way to eliminate his iCloud account and make mine the primary without rebooting it back to factory settings? There was an update, I believe, that I couldn't install because i didn't have his password that is what made me aware that his acct. was still active. I don't know what to do. Any help is greatly appreciated. Thank you.

Before buying a second-hand computer, you should have run Apple Diagnostics or the Apple Hardware Test, whichever is applicable.
The first thing to do after buying the computer is to erase the internal drive and install a clean copy of OS X. You—not the original owner—must do that. Changes made by Apple over the years have made this seemingly straightforward task very complex.
How you go about it depends on the model, and on whether you already own another Mac. If you're not sure of the model, enter the serial number on this page. Then find the model on this page to see what OS version was originally installed.
It's unsafe, and may be unlawful, to use a computer with software installed by a previous owner.
1. If you don't own another Mac
a. If the machine shipped with OS X 10.4 or 10.5, you need a boxed and shrink-wrapped retail Snow Leopard (OS X 10.6) installation disc from the Apple Store or a reputable reseller—not from eBay or anything of the kind. If the machine is very old and has less than 1 GB of memory, you'll need to add more in order to install 10.6. Preferably, install as much memory as it can take, according to the technical specifications.
b. If the machine shipped with OS X 10.6, you need the installation media that came with it: gray installation discs, or a USB flash drive for a MacBook Air. You should have received the media from the original owner, but if you didn't, order replacements from Apple. A retail disc, or the gray discs from another model, will not work.
To start up from an optical disc or a flash drive, insert it, then restart the computer and hold down the C key at the startup chime. Release the key when you see the gray Apple logo on the screen.
c. If the machine shipped with OS X 10.7 or later, you don't need media. It should start up in Internet Recovery mode when you hold down the key combination option-command-R at the startup chime. Release the keys when you see a spinning globe.
d. Some 2010-2011 models shipped with OS X 10.6 and received a firmware update after 10.7 was released, enabling them to use Internet Recovery. If you have one of those models, you can't reinstall 10.6 even from the original media, and Internet Recovery will not work either without the original owner's Apple ID. In that case, contact Apple Support, or take the machine to an Apple Store or another authorized service provider to have the OS installed.
2. If you do own another Mac
If you already own another Mac that was upgraded in the App Store to the version of OS X that you want to install, and if the new Mac is compatible with it, then you can install it. Use Recovery Disk Assistant to prepare a USB device, then start up the new Mac from it by holding down the C key at the startup chime. Alternatively, if you have a Time Machine backup of OS X 10.7.3 or later on an external hard drive (not a Time Capsule or other network device), you can start from that by holding down the option key and selecting it from the row of icons that appears. Note that if your other Mac was never upgraded in the App Store, you can't use this method.
3. Partition and install OS X
a. If you see a lock screen when trying to start up from installation media or in Recovery mode, then a firmware password was set by the previous owner, or the machine was remotely locked via iCloud. You'll either have to contact the owner or take the machine to an Apple Store or another service provider to be unlocked. You may be asked for proof of ownership.
b. Launch Disk Utility and select the icon of the internal drive—not any of the volume icons nested beneath it. In the Partition tab, select the default options: a GUID partition table with one data volume in Mac OS Extended (Journaled) format. This operation will permanently remove all existing data on the drive.
c. An unusual problem may arise if all the following conditions apply:
          OS X 10.7 or later was installed by the previous owner
          The startup volume was encrypted with FileVault
          You're booted in Recovery mode (that is, not from a 10.6 installation disc)
In that case, you won't be able to unlock the volume or partition the drive without the FileVault password. Ask for guidance or see this discussion.
d. After partitioning, quit Disk Utility and run the OS X Installer. If you're installing a version of OS X acquired from the App Store, you will need the Apple ID and password that you used. When the installation is done, the system will automatically restart into the Setup Assistant, which will prompt you to transfer the data from another Mac, its backups, or from a Windows computer. If you have any data to transfer, this is usually the best time to do it.
e. Run Software Update and install all available system updates from Apple. To upgrade to a major version of OS X newer than 10.6, get it from the Mac App Store. Note that you can't keep an upgraded version that was installed by the original owner. He or she can't legally transfer it to you, and without the Apple ID you won't be able to update it in Software Update or reinstall, if that becomes necessary. The same goes for any App Store products that the previous owner installed—you have to repurchase them.
4. Other issues
a. If the original owner "accepted" the bundled iLife applications (iPhoto, iMovie, and Garage Band) in the App Store so that he or she could update them, then they're irrevocably linked to that Apple ID and you won't be able to download them without buying them. Reportedly, Mac App Store Customer Service has sometimes issued redemption codes for these apps to second owners who asked.
b. If the previous owner didn't deauthorize the computer in the iTunes Store under his Apple ID, you wont be able to authorize it immediately under your ID. In that case, you'll either have to wait up to 90 days or contact iTunes Support.
c. When trying to create a new iCloud account, you might get a failure message: "Account limit reached." Apple imposes a lifetime limit of three iCloud account setups per device. Erasing the device does not reset the limit. You can still use an iCloud account that was created on another device, but you won't be able to create a new one. Contact iCloud Support for more information. The setup limit doesn't apply to Apple ID accounts used for other services, such as the iTunes and Mac App Stores, or iMessage. You can create as many of those accounts as you like.

Home Hub 3-- Re-activating BTWIFI and BTFON signal...

I have a Home Hub 3 and some days ago I had to do a factory reset on it. After that I had lost the BTWIFI and BTWIFI-with FON hotspot signals from the hub.
When I logged in to the hub it said “You aren't currently part of the BT FON WiFi Community”.
I found this page on your website: http://bt.custhelp.com/app/answers/detail/a_id/12987/~/i%27ve-changed-my-bt-home-hub-and-my-bt-wi-fi...
I carried out the instructions to opt out and to opt in again, but after 3 days nothing had happened. There were still no hotspot signals from the hub and if I looked at the hub it still said “You aren't currently part of the BT FON WiFi Community”, despite the fact that if I checked my status online it said “opted in”.
I then called the support number 0800 022 3322 recommended on this forum and got the Indian call centre who told me that home hubs do not have a dedicated hotspot signal and that the problem was due to a lack of hotspots in my area….!!!
I then sent a support message using the BT support contact form describing the above problem and asking if they could re-instate the signals manually. This is the reply I received:
“*removed
This reply was also from India and needless to say, I did not phone the help desk as suggested, as this was the same number that had failed me previously. It is obvious that BT staff in India are not aware of how BT provide hotspots in the UK.
I opted out and in again once more at that point, but it is now 5 days since my opt in and nothing has happened at the hub.
So my question is, is there a way of contacting someone in BT in the UK who understands the problem and can arrange for the hotspot signals to be re-activated on the hub.
After all, they were de-activated inadvertently, and you would think that it would be in BT’s interests to activate them again as soon as possible.
I have no complaints about the BT broadband service, and I can understand the need for them to use an inexpensive call centre to filter out most of the simple queries, but in situations where the staff do not understand or cannot help they should refer the customer back to someone in the UK qualified to solve the problem.
Solved!
Go to Solution.

All power to the Mods! I had a letter from Stuart this morning saying he had checked my hub status and that it was queued for activation and that it should happen within 48 hours, but by the time I read his letter it was already activated. He thinks it was a combination of luck and co-incidence, but I blame divine intervention.
So I have marked SJTP’s post as the accepted solution. Thank you.
However, it should not be necessary to resort to these forums and the mods to resolve a problem like this, so I am going to suggest the following to any BT employees who might be interested.
While having a call centre in India is an inexpensive way of dealing with most of the problems raised by BT’s clients, there will always be some problems that are not resolved or are advised badly due to the limited training of call centre staff. At present BT send a customer satisfaction survey after any query of their call centre, but the results are used for their own purposes. What I would suggest is that any unresolved issues at that point should result in the client being given a contact to a UK based technical team so they can have some hope that their issue would be resolved.
This would create a huge boost to BT’s image amongst users and would probably greatly reduce the number of issues on this forum, particularly the ones resulting in negative press for BT.
