Replace standby server in CCX 8.02su3 HA cluster

Hej.
I am replacing the standby server (secondary node) in a CCX 8.02su3 cluster because of hardware failure.
I can only find the procedure for replacing the primary node on cisco .com.
Here is what I attend to do :
1. Remove secondary node (server name) from primary node's www under System->Server
2. Take backup of primary node
3. Add secondary node (server name) in primary node's www under System->Server ( Same ip, sub etc as old secondary node but new mac)
4. Start installation on secondary node (with adding patches in the installation phase so the server comes to SU3 with the same)
5. Take full backup of cluster.
Don't if step 1 (and 3) is nessesary..
Can anyone please verify this procedure.
Thanks in advance
Thomas

This is exactly what you need to do if you are reinstalling the second server.
Thank you
Rajani

UCCX Active / Standby server

Hello,
We have UCCX HA pair. I am trying to find out the current active and standby server. How can I do this? How do I know which of the 2 server is Active and Standby. Also, which server should be active? Should Publisher be Active? or Subscriber be active?
Thank You,

It doesn't matter which server is active. Both will work. I try to keep my publisher the active (master) server as this is what the CAD clients are configured to connect to first.
To find out which one is currently the master, log in to Cisco Unified CCX Serviceability (from drop down menu in top right of appadmin), select tools --> control centre. Select your node, if the CCX Engine has a blue box with an M - it is currently the master. If it is an S, it is currently the slave.

Will RMAN delete archive log files on a Standby server?

Environment:
Oracle 11.2.0.3 EE on Solaris 10.5
I am currently NOT using an RMAN repository (coming soon).
I have a Primary database sending log files to a Standby.
My Retention Policy is set to 'RECOVERY WINDOW OF 8 DAYS'.
Question: Will RMAN delete the archive log files on the Standby server after they become obsolete based on the Retention Policy or do I need to remove them manually via O/S command?
Does the fact that I'm NOT using an RMAN Repository at the moment make a difference?
Couldn't find the answer in the docs.
Thanks very much!!
-gary

Hello again Gary;
Sorry for the delay.
Why is what you suggested better?
No, its not better, but I prefer to manage the archive. This method works, period.
Does that fact (running a backup every 4 hours) make my archivelog deletion policy irrelevant?
No. The policy is important.
Having the Primary set to :
CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON STANDBYBut set to "NONE" on the Standby.
Means the worst thing that can happen is RMAN will bark when you try to delete something. ( this is a good thing )
How do I prevent the archive backup process from backing up an archive log file before it gets shipped to the standby?
Should be a non-issue, the archive does not move, the REDO is transported and applied. There's SQL to monitor both ( Transport and Apply )
For Data Guard I would consider getting a copy of
"Oracle Data Guard 11g Handbook" - Larry Carpenter (AKA Dr. Paranoid ) ISBN 978-0-07-162111-2
Best Oracle book I've read in 10 years. Covers a ton of ground clearly.

Logical standby server stopped applying changes

Hi
I set up a logical standby database with database guard and it worked fine for some time. But recently I had to use it again and discovered that applying changes from primary database to secondary database just stopped working. I see in V$ARCHIVED_LOG one entry per day. If I restart the logical standby then the changes from primary server are also applied. But if I just make a change on primary server and even call 'alter system switch logfile' then I see an entry in V$ARCHIVED_LOG on primary server but not on standby server (BTW in general there are much more entries in this view on the primary server). I checked pairs of log files indicated by the parameter *.log_file_name_convert in standby server's spfile: their last changed date is always the same.
I will paste spfile of my standby server (dh5). Primary server name is dh2.

Hi,
Nice to hear you issue got resolved.
It is good practice to keep monitoring the progress of SQL apply on the logical standby on a regular basis.
You can mark my response as helpful if it has helped you.

I just purchased the Mac Mini Server with the intention of replacing Lion Server with Lion for the first hard drive while installing Windows 7 thru Bootcamp on the second hard drive. Is it possible for me to do this? Thanks.

I just purchased the Mac Mini Server with the intention of replacing Lion Server with Lion for the first hard drive while installing Windows 7 thru Bootcamp on the second hard drive. Is it possible for me to do this? Thanks.

I would use Parallels or VMWare and use the second drive to hold the virtual machine. That way the VM only uses the space that it needs and you can still use the remainder of the drive for other things, not to mention that you would not need to reboot to run windows.
Also Time Machine does not back up a boot camp partition.

Archived log to standby server stopped

Hi,
I configured dataguard standby server few weeks ago,
I set log_archive_dest_2='SERVICE=JHRD0107_OFS1 OPTIONAL'
and log_archive_dest_state=ENABLE in primary server,
and very go fine until yesterday, I shutdown my standby server and set the log_archive_dest_state=DEFER,
when I tried to startup again the standby server, and set log_archive_dest_state=ENABLE again,
the archive stop sending the archived log to log_archive_dest_2.
No error was found in alert log of primary and standby server.
It seem that the primary server don't know there is another archive destination..
The database version is 10g 10.2.0.4
Anyone what could be the cause of this?
Thanks

How to migrate an existing Microsoft SSIS deployment if it is decided to replace SQL Server with an Oracle database?

Hi Oracle Gurus!
Currently, I am designing an ETL solution that transforms and loads a lot of data from flat files and sends it to an SQL Server 2008 R2 database for storage. However, at a future point of time, it may be decided to add or even replace SQL Server with an Oracle 11g database.
Currently, I am writing script transforms in C# to dynamically generate SSIS packages to tansform and load the data into SQL Server. But considering that in future, an Oracle 11g or 12c database might be added to, or replace the SQL Server database, how do I make my script transforms (or whatever else I am developing currently for SQL Server) reusable to the extent possible?
Or more precisely, what steps do I take, from an Oracle point of view, to ensure that any future migration of data to an Oracle database would be smooth to the extent possible?
Looking up to my Oracle Gurus for enlightenment in this matter!
Novice Kid

When you're writing your on C# code to load data into the SQL Server you have to modify the routines so that they will work with Oracle.
One approach is to use the extproc agent which would allow you to directly call external programs with all the logic in it to perform the load of your files and to put the data into the Oracle database. Another option would be to use utl_file package (or equivalents) which will allow you to open external files from your Oracle database and to directly read its content and then to pass it to the related tables.

Standby server in oracle9i standard edition under linix

I want to know more abt the standby server option on oracle 9i standard edition, whether is it possible or not, if yes give me step by step doc and useful scripts for automating the system.
thanx in advance.

UCCX 8.0 SNMP notification to report failover from active to the standby server?

Does any know the UCCX 8.0 SNMP notification to report failover from active to the standby server? (The specific notification.)
ftp://ftp.cisco.com/pub/mibs/v2/CISCO-VOICE-APPS-MIB.my
I see this in the MIB.
cvaModuleStart NOTIFICATION-TYPE
OBJECTS   { cvaAlarmSeverity, cvaModuleName }
STATUS    current
DESCRIPTION
        "A cvaModuleStart notification signifies that an
        application module or subsystem has successfully
        started and transitioned into in-service state.
        This notification is working in conjunction with
        the cvaModuleStop notification to notify the start
        and stop status of a particular application module."
::= {ciscoVoiceAppsMIBNotifications 1}

Attached are two files:
cad-ecc-viewer.html
This is a template HTML document which dictates how the pop up will look and what data fields are available.
cad-ecc-viewer.vbs
This is the Windows Scripting Host file which you run from a CDA workflow, and you pass it the values of the call data, it then launches an instance of IE and loads the above template.
By default the code is setup to use the following data from the call, but can be modified to work with more, less, or different data:
Customer Name
Customer Status (like Premium, or Platinum)
Customer Number (like an account number)
Customer Phone Number
So when you specify the VBS file to run in CDA you need to pass those variables in that order.
The CDA should expect the VBS file on the root of C:\ by default, and the VBS file expects the HTML Template on the root of C:\ also.
I have only tested this on UCCX 7x and IE 8x. Use the code as a guide to your own solution, that suites your business requirements.
EDIT: I see that this does not work on my Win7/IE9 system, so I will spend some time updating the code for Win7/IE9 and I'll let you know how it goes.

Hi,
I've seen that, if the following message persists for a long time, then it is an ERROR.
FAL[client]: Failed to request gap sequence GAP - thread 1 sequence 17857-17863 DBID 3371425568 branch 681431456 FAL[client]: All defined FAL servers have been attempted.
The possibility is that log shipping of 17857 is stuck. It is not stuck because of any network disconnect, as it is in the case you mentioned. It is probably due to the following.
The parameter LOG_ARCHIVE_DEST_1 on standby is set as L:\ORACLE\A30\ORAARCH\A30ARCH\ARC and STANDBY_ARCHIVE_DEST is also set to L:\ORACLE\A30\ORAARCH\A30ARCH\ARC. When a GAP is identified, standby database tries to pull the missing files FROM PRIMARY, and the in turn when you enable standby destination on primary (log_archive_dest_state_2 = enabled), it starts shipping logfiles on its OWN.
When such a situation occurs in a system when archived logs are generated at a high rate, it can happen that the file which standby is trying to pull is being pushed/already pushed by primary database. Then a conflict arise, and standby deletes the file and tries to pull it again...this may go on in a loop. (because the locations are SAME).
When i had this issue, I maintained different locations for LOG_ARCHIVE_DEST_1 and STANDBY_ARCHIVE_DEST on standby database. After this is done, you will find that the logs shipped by primary are written in STANDBY_ARCHIVE_DEST. The file written in this location will be used by the standby database only when you do a managed recovery. If you are doing a manual recovery by issuing the command RECOVER STANDBY DATABASE; then, the stanbdby database will check if the file exists in LOG_ARCHIVE_DEST_1.
The point is, when there is BIG gap, then you have the option of doing the following procedure.
1. On the primary database keep LOG_ARCHIVE DESTSTATE_2 = enable
2. On the standby ALTER DATABASE RECOVER MANAGED STANDBY DATABASE CANCEL.
3. Copy the missing archive logs sequence from the primary to standby's LOG_ARCHIVE_DEST_1 and perform manual recovery on standby untill the gap is over.
4. issue the command ALTER DATABASE RECOVER MANAGED STANDBY DATABASE DISCONNECT to start managed recovery. ( This will use the files present in STANDBY_ARCHIVE_DEST ).
Hope the above procedure helps.
Note: If the GAP is not that big and you see that last applied log is advancing, then conflict is not there...standby will automatically fill the GAP. But it is advised to maintain different location for the parameters i mentioned.
Regards,
Anish

Upgrading Unity 4.0.5 to version 8 and replacing the server. Need advice for most efficient upgrade path.

Hello,
I need to upgrade Unity 4.0.5 without failover to Unity 8, and we are replacing the server as well.
What would be the most efficient upgrade path for this?
Thanks!!

Brian,
The most efficient path is to use COBRAS. I have a number of posts explaining the overall process. At the highest-level, this allows you to build out the new Unity 8x environment, get it integrated with AD/Exchange, and then build out configurations that don't migrate over (there are a few which are highlighted in the COBRAS help). From there, you migrate data over from the 4x system. There may or may not be a few steps along the way but they are outlined in numerous posts I've contributed to regarding COBRAS and also in the COBRAS Help which is located at www.ciscounitytools.com.

Oracle 10gR2 Data guard physical or logical standby server?

Hi
We are planing to implement an Oracle 10gR2 data guard standby server for DR purposes, I found out that there are two type of standby server which is logical and physical standby server. I want to know which one is preferable? in term of complexity of setup and maintenance?
regards

Well it depends on what you mean by maintenance. I found the physical standby to be very little trouble at all ; however the logical standby has restrictions on it that the physical standby does not. In essence the physical standby merely digest archive logs; where as the logical standby uses logminer like functionality to process sql statements much like Oracle streams.
Hope that helps,

Replacing Essbase server , different drive letter

Will be getting a replacement Windows server for our Essbase software & apps(don't have it yet). The directory structure will be the same(\Hyperion\Essbase\...)but not the drive letters.The existing server has a C:(OS) and a D:(data drive). The new server will have a C:(OS) and E:(data drive-this is based upon IT standardization).My plan is to install software and copy Hyperion directories & subdirectories from old to new. I have done this copy in the past when the drives letters are the same, but will it work when the drive letters are different?My main concern is the security file. Will the copy work for security or will I be forced to rebuild security?

You need to re-start the application in order that it takes the new setings.But in order that it moves the files to another drive, you need to export the database (all data), clear the data (clear all data) and to import the data again from the exported file.hope that helpsClaudio

Why FRA filling faster in logical standby server.

I have two standby servers one physical and one logical for my primary database. I have notice that on logical standby server the FRA is filling faster then physical standby server. Any one have some suggestions.
Thx

>

That is to be expected, because the logical standby not only creates archive logs on behalf of the transmission from the primary but also generates its own archivelogs on behalf of the filling (& archiving) of the local online logfiles. If you watch a logical standby applying, you may notice that the standby logs are getting archived and the online logs as well. That is significant for a logical standby and leads to (at least temporary) higher space consumption in the recovery area. Temporary, because the applied archive logs can get deleted (automatically, if you allow that).
