XI System backup and restore for the JAVA Stack

Hello experts
I am few queries regarding backup of XI System.
1- What is the procedure to backup the XI System on AIX OS?
2- Should I backup the J2EE Engine also with Jload and Java migration toolkit, when I backup the XI System?
3- If XI system crashes, what is the procedure to restore XI system from backup?
4- Do I have to restore the J2EE Engine also from backup with XI with the help of Jload and Java migration toolkit. If so, what is the procedure on AIX OS?
5- If I take a backup of XI system, after 3 days the server crashes. When I restore the backup, how should I recover the lost messages of 3 days?
Kindly help me out with these issues. If anybody has any documents, kindly email me at [email protected] Points will be rewarded for any kind of help. Thanks a ton in advance.

Hi Bipin,
This blog contains very little info. It says zip the XI files and extract the compressed zip files. Also it talks about backup of registry.
I am on AIX OS. How can I backup the registry in AIX? Also how should I zip all the files and extract those compressed files during restore. Is there any SAP utility to do that. Kindly let me know.

Can someone help.
I tried doing my backup restore on the same computer as I once did a year ago. and THis time I cant do the restore on the iphone.
computer osx is 10.5.8

I do not wish to go to ios 7 at this time.

Settings > General > Reset > Reset Network Settings.
Basic troubleshooting is reset, restart, restore (first from backup then as new). Try each of these in order until the issue is resolved.
If the issue continues, contact the carrier to troubleshoot the network connectivity issues.

Windows 8 full system backup and restore to new laptop (system with 32GB mSata Cache)?

Hi, I have a new Envy DV7-7205 which has 2TB storage with 32GB HDD Cache (or mSata, not really sure how it's implemented). I need to return the laptop as it's faulty but I would like to startup on the replacement exactly where I left off.
Are there any special methods required to backup and restore the system image from the old laptop to the new one, particularly with consideration to the 32GB SSD cache, as this doesn;t seem to appear as a distinct "drive" on the system.
Please can anybody advise the simplest, safest method to move my entire system from old to the new laptops (should be exactly the same spec machine).
Many thanks,
Greg

Hi,
Firstly I don't know how this is going to work on new machine because the Windows 8 lisence would NOT work at all.

RMAN backup and restore for Disaster Recovery

Hi Guys,
I am very new to Oracle and have a question about RMAN backup and restore feature. I am simulating a disaster recovery scenario by having two VMs running oracle 11g, say hosta and hostb, hosta is sort of production db and the other a disaster recovery db (one that will be made primary when disaster occurs). My goal is to backup production db using RMAN and restore it on the other machine. For some reason when I restore the db on hostb, the command restores the previous backup but not the most recent one e.g. I took a backup yesterday (09/20) and applied it to the hostb that worked fine, but when I try to apply a fresh backup from today (09/21) it always picks up the old backup. Here's a dump of the screen:

Thanks guys, I really appreciate all your help here. I redid everything all over again to get all the information you guys wanted. Since I noticed that more eyes are looking into this I am going to reiterate my steps one more time followed by specific answers to questions. My first backup on Host B is located under ..../restore_db/backupset whereas the subsequent one is under .../restore_db/backupset/backupset2.
I take backup on Host A using:
rman target /
backup as compressed backupset database plus archivelog;
backup spfile;
quit;
I restore the backup on Host B using:
set dbid=13732232063;
startup force nomount;
restore spfile to '/oracle/app/dev/product/11.2.0/dbhome_1/dbs/spfileforums.ora' from '/export/home/dev/restore_db/backupset/o1_mf_nnsnf_TAG20110928T171830_787gbpxh_.bkp'
shutdown immediate;
startup force nomount;
restore controlfile from '/export/home/dev/restore_db/backupset/o1_mf_ncsnf_TAG20110928T171638_787gbkxn_.bkp'
quit;
/* restart rman here */
alter database mount;
catalog start with '/export/home/dev/restore_db/backupset' noprompt;
restore database;
recover database;
alter database open resetlogs;
quit;
I take another backup on Host A using (notice no spfile backup this time):
backup as compressed backupset database plus archivelog;
quit;
I restore the database on Host B using:
alter database mount;
catalog start with '/export/home/dev/restore_db/backupset/backupset2' noprompt;
recover database;
alter database open;
quit;
Output of List Backup of database (I have done this after I recovered the second time, also note that it is referring to backupset2 which is were my second backup is stored)

Algorithm for online backup and restore of the entire grid

Hello!
I am trying to write a utility program that backs up the entire grid data to a binary file and restores it at a later point in time. Assuming that the class files are not updated, I am using the following simple logic
1. Use the cluster and CacheService APIs, get the names of all named caches of types replicated, distributed and optimistic
2. Iterate through each named cache and use ExternalizableHelper.writeMap method to extract the data as byte arrays
3. Create a custom datagrid object holding a map of byte arrays by names
4. Write the custom object to a persistent storage
Similar logic to restore the data grid from the custom object on the disk.
I have the following questions
1. I am sure the above logic is not going to recreate the entire datagrid in the exact state it was backed up. For e.g. if I used write-behind, I must either flush or backup the write-behind queue. What other objects should
I consider backing up other than the data from the named caches? If I used the incubator patterns, I am guessing I need to backup the command objects and functor objects.
2. I do not have a need for other cache services now. If I need to use the same utility across different grid configurations, what other services should I include for the back up (overflow, external, paged external) ?
3. Are there best practices for such use cases? Any insights you can provide to enhancing this utility would be much appreciated.
Thank you
Regards,
Sairam

Hi Sairam,
If you want a non-intrusive solution then you cannot really use cache stores, as these would certainly intrude into the cluster. Cache stores would also not really be an option if the cluster already used another type of cache store - unless you write some sort of multiplexing cache store.
If your backup/restore solution needs to be a "client" (optionally over Extend) then you have two choices:
1. Build something that is run whenever you want to do a backup - this would usually be an Extend client application. This application would then read data out of the caches and write it to disk. With this option a backup might take a while if the cluster is large but running the backup is pretty easy.
2. Build something that is permanently connected to the cluster being backed up and uses Map listeners to listen for inserts and updates and stores the data to disk. This application could be either an Extend client or a storage disabled cluster member. With this option your cluster is always backed up in real time but you have the overhead of another process to manage.
If all your caches use POF serialisation then either of the above options could be written to just store the POF binary without having to deserialize it and could then be "bolted on" to any cluster. Re-loading stored binaries would need a bit of thinking about although a couple of options come to mind. If you just worked with the binary you might not need to worry about you backup application needing the pof-config of the cluster.
You backup application would need to either be told which caches to back up or be able to dynamically figure out what caches had been created. You cannot always do this from the cache config file if the cache names in the mappings section use wild card names.
As you can see there is lots to think about if you want to build something truly non-intrusive.

to my new Lenovo server running windows server 2012 r2 and restore everything? will it copy the 2008r2 at 100 percent?
in other words have everything from my 2008r2 server on my new 2012r2 server
any help will be appreciated
thanks in advance

Hi,
We could not restore the server 2008 r2 backup on server 2012 r2. System State Recovery is only supported on the same operating system instance. It is not supported on a reinstalled operating system on the same or different hardware.
For more detailed information, please refer to the article below:

If your iPhone is jailbroken then it doesn't have a virus.
Your problem is most likely something else and the chances of your computer catch it are nonexsistant.

System backup and restore

Hi, all
This thread mentions a method to store a backup of relevant parts of the filesystem, and how to restore it. Akin to windows system restore.
gazj wrote:
Using tar is the most simple way smile
tar cvpzf backup.tgz --exclude=/proc --exclude=/lost+found --exclude=/backup.tgz --exclude=/mnt --exclude=/sys /
This will create a file backup.tgz in your / folder
To restore - Just do a base install and run this command or you could even untar it into an empty partition from the install cd
tar xvpfz backup.tgz -C /
Is this still ok to do? It seems simple and effective enough.

Yes it should work - there are lots of other options here. Personally, I find rsync to be much better suited to such a task.
But I mainly wanted to comment to disuade you from doing it exactly as you describe: a backup of a filesystem saved on that filesystem wouldn't be of any use in the times you'd really need it.

HT1766 I got my iPhone 5 replaced and had to backup and restore with the cloud, but all my apps started disappearing one by one??

I had backuped my phone before and after I got the iOS7 update. Then, I went to the apple store to change my phone for a new one because my old one had a hardware issue with the camera. It was all going smoothly until I saw each and every one of my apps disappearing one by one...The people at the store told me that it was because I had a bad backup (which could be caused by multiple reasons)??? So we tried doing it three times with different backup times, and this kept on happening. Why is this happening and what do I do to get my apps back, hopefully with the latest backup I had done prior to this disaster???? Please help!!

Morning Vjohara,
Thanks for using Apple Support Communities.

Backup and restore to the other database with Recovery Catalog

Dear All,
i need your help about recovery catalog.
I have 3 databases, 2 databases version are 8.1.7.3 (HostA and HostB) and other database is 9.2.0.6 (as Catalog Database)
I want to backup files from HostA with Catalog Database into tape, then restore the backup files into HostB.
Please suggest me how to do this.
Best Regards,
abip

you can achieve this with the rman duplicate command.
if you have the same directory structure then it is a relatively simple task, if the directory structure is different then you need to use the
'set newname' syntax.

A New MBP (and one for the road: any highly-recommended external drive for.

If I order a new MBP 17" for architecture and planning grad program, will SL come installed on the machine? Is SL considered a whole new OS or jut an update to Leopard? I am not even sure I am wording the questions correctly, so I apologize if I am not. I stopped at Tiger because the Leopard OS looked a bit too intimidating for me back then but I think I can deal with it now. Is it a big set-back that I did not learn how to use Leopard and now I am getting SL?
thanks for any help in this area.
I will throw this out there. I also need a decent but very heavy duty external hard drive to use for the work done with CAD. Any recommendations on a top-of-the-line heavy duty external hard drive? I guess the case is the main thing but the drive should be able to take some extra abuse because I baby the MacBook Pros but sometime the external drives get the abuse. I think USB2.0 is good enough for what I need.
Thanks Again

I would imagine that you could turn up good and bad reports on any drive. I have been highly satisfied with my 3 LaCies, two dating back to 2004. And, LaCie has very good phone support.
I use only clones and drag and drop for data changes between clonings. If I had to choose one method of backing up, then I definitely would use this process. Still, one can take a dual approach other than mine. The idea is to have a clone, which is updated fairly recently, to serve as a fail-safe, system backup, and restoration device. And, one could still use TM for day-to-day backups because of the flexibility it allows in moving backwards in time to retrieve data and because it updates automatically frequently. I want to experiment more with TM. So, I will move to this sort of dual system in the near future--as soon as I figure out which partition on my main external I can do without.
For cloning, I like SuperDuper because it has the ability to make incremental clones--thus, shortening the recloning process significantly. CCC is good, but I have never used it. Actully, Disk Utility is a highly respectable cloner, but it does not have as many options as the others, including not having the ability to make incremental clones.
