Oracle DB among Multiple Sites

Helo DBAs
I have six sites running oracle databases, accessing between any of them at any time.
5 sites running Oracle 8i and One site running 11g.
Each site having number of computers, installed with Oracle Client 8i
All the sites connected by 64kbps dedicated leased lines.
The issue is,
the application runs much slower when accessing the remote db.
Is there any tuning methods to be applied to make it faster either in server or client ?
Have any hints, welcome please...

Too many to list here. The biggest thing is to minimize the amount of data that has to be pushed over the wire. This means doing as much of the work as possible in the server itself. Make sure you are fully utilizing the features available within oracle to filter and message your data before sending it back to the client. Many programmers just treat the db as a data dump, pulling too much data into the client for processing that could have been done by the data base. An example of such coding would be to create a cursor based on an unqualified SELECT and fetching every row (across the wire, mind you) into the client for filtering and deciding on a row-by-row (slow-by-slow) UPDATE to push back across the wire -- all when a single, well crafted UPDATE could have been pushed across the wire on time.

Share an ASM disk group among multiple nodes

According to Oracle documentation:
*“To share an ASM disk group among multiple nodes, you must install Oracle Cluster ware on all of the nodes, regardless of whether you install Oracle RAC on the nodes”.*
And if I understand it right to share the same ASM storage group from multiple nodes from separate RACs or multiple non-RAC nodes ASM instances in those nodes need to communicate to synchronize ASM related metadata using same technique like cache fusions.
My question is how this ASM communication take place among different ASM instances located in different RACs and standalone servers. Do we have to have some kind of Interconnect settings among the nodes?

Hi,
ASM and database instances require shared access to the disks in a disk group. ASM instances manage the metadata of the disk group and provide file layout information to the database instances.
ASM instances can be clustered using Oracle Clusterware; there is one ASM instance for each cluster node. If there are several database instances for different databases on the same node, then the database instances share the same single ASM instance on that node.
If the ASM instance on a node fails, then all of the database instances on that node also fail. Unlike a file system failure, an ASM instance failure does not require restarting the operating system. In an Oracle RAC environment, the ASM and database instances on the surviving nodes automatically recover from an ASM instance failure on a node.

Managing multiple sites in different iWeb versions - PLEASE HELP!

apnewbie/cyclosaurus/roddy/old toad (and any others more knowledgeable than i):
i've run into a bit of a pickle. i am hoping someone can help straighten me out. i am about to jump out of a window. here's the rundown:
(for starters, i have a .mac account and am publishing to .mac.) i created a site in iWeb 1.1.2 on my work computer (mac book pro). worked great, really lovely. thought to myself, "hey, i'd like to create another site from home, but i don't have iWeb at home (powerbook G4) - i should buy iLife 08 so i can build these things from home and not have personal files on my work computer."
so: i had a site that i created within 1.1.2 with files written to iDisk. i purchased iWeb 08 and would like to have another site, but this one is being created in 2.0. i also am using a personal domain name this time around bought with google apps and hosted by godaddy. i published the new work in progress for a test run and...you guessed it...my original 1.1.2 site was rewritten by the 2.0 site. and the 2.0 site comes up as the standard google search page for domains that aren't up and running. whooopsie.
sorry for the lengthy intro, but that's the background. i guess my specific questions are:
1) i want to be able to maintain multiple sites from iWeb 2.0...can i open my 1.1.2 domain file in 2.0 and successfully bring that site into 2.0?
2) what is the most efficient and easiest way to get both of these sites running in 2.0? right now i have two domain files (created on two different computers).
3) for domain management, is it best to move from the iWeb folder in my home library to different folders (one for each site, with separate domain files, and my 2.0 domain file is NOT called domain, it's the name of the site) to another location? (and of course, i will back these up just in case.) and when i want to update a site, i just open that individual domain file, right? or will these sites publish over each other?
please help. i am at my wits end. i'm sure this is a relatviely simple issue, but i'm new to iWeb.
thanks, thanks, thanks for your help guys.

joojy,
Welcome to the forums!
First of all, your original 1.1.2 site may not, in fact, have been overwritten. It is quite possible that the site remains in it's position on the iDisk, Web/Sites/iWeb/YourSite, but because you published to the iDisk (.Mac) from 2.0, a different index.html file has been placed in the root level Web directory which is causing the 404 error. Navigate to the directory on the iDisk, using the Go menu in Finder, and look to see what is actually there. Follow this path:
Go/iDisk/My iDisk/Web/Sites/iWeb/YourSiteWillBeHereIfYourLuckIsGood
If your site is there, great; if it isn't, it's not really a problem because hopefully you still have the Domain.sites file on the MacBook Pro and you can republish it if necessary. If it is there, you can modify the index.html file on the iDisk using a text editor and get your url redirected back to where it should be.
Second, do not open your 1.1.2 Domain.sites file with 2.0 until you have a backup of this Domain file. External drives are best for this. Assuming the backup is in place, launch 2.0, choose the Domain.sites file, and click on "update". It will be updated to a Domain.sites2 file. If the site looks ok then continue on with editing/publishing.
Skipping to question (3), by all means, abandon the default location of the Domain.sites file in the Home folder's Library and get accustomed to keeping your Domain files in their own, respective folders. When you want to open one just double-click it.
You are going to encounter difficulties publishing multiple sites in 2.0.2, unless you keep all of the sites in a single Domain file. 2.0 is publishing to a different directory on the iDisk than 1.0; it publishes to /Web/Sites/, as opposed to /Web/Sites/iWeb/. Publishing a site from a separate Domain file erases previously published sites. I have been able to publish multiple sites, from multiple Domain.sites2 files, by mounting the iDisk and actually moving the Site folder back one level, into the root Web folder, and then publishing. When finished, I move it back again. If you have RSS feeds you will probably get a 'file in use' error. The alternative, (other than keeping all sites in a single Domain), is to publish the site to a folder and then manually drop the Site folder into the Web/Sites/ directory on the iDisk. Of course, some .Mac functions are lost when publishing this way.
Work through this info and post back.

Azure multiple site-to-site VPNs (dynamic gateway) with Cisco ASA devices

Hello
I've been experimenting with moving certain on-premise servers to Azure however they would need a site-to-site VPN link to our many branch sites e.g. monitoring of nodes.
The documentation says I need to configure a dynamic gateway to have multiple site-to-site VPNs. This is not a problem for our typical Cisco ISR's. However three of our key sites use Cisco ASA devices which are listed as 'Not Compatible' with dynamic routing.
So I am stuck...
What options are available to me? Is there any sort of tweak-configuration to make a Cisco ASA work with Azure and dynamic routing?
I was hoping Azure's VPN solution would be very flexible.
Thanks

Hello RTF_Admin,
1. Which is the Series of CISCO ASA device you are using?
Thank you for your interest in Windows Azure. The Dynamic routing is not supported for the Cisco ASA family of devices.
Unfortunately, a dynamic routing VPN gateway is required for Multi-Site VPN, VNet to VNet, and Point-to-Site.
However, you should be able to setup a site-to-site VPN with Cisco ASA 5505 series security appliance as demonstrated in this blog:
Step-By-Step: Create a Site-to-Site VPN between your network and Azure
http://blogs.technet.com/b/canitpro/archive/2013/10/09/step-by-step-create-a-site-to-site-vpn-between-your-network-and-azure.aspx
You can refer to this article for Cisco ASA templates for Static routing:
http://msdn.microsoft.com/en-us/library/azure/dn133793.aspx
If your requirement is only for Multi-Site VPN then there is no option but to upgrade the device as Multisite VPN requires dyanmic routing and unfortunately there is no tweak or workaround due to hardware compatibility issue.
I hope that this information is helpful
Thanks,
Syed Irfan Hussain

Syncing the same iTunes library among multiple computers

I have two computers, a Windows 7 laptop and a new iMac. iTunes on both computers are signed into the same Apple ID. I currently have my iTunes library on my laptop, but I would like to also have the exact same library on my iMac. For instance, if I download a new podcast to my laptop, it should be placed on my iMac as well. When I delete the podcast, it should be deleted on the iMac too. When song metadata is updated on my laptop (play count, lyrics, etc), I want it updated on the iMac automatically.
I have not had much experience with Home Sharing, but would that do all of this automatically? I know I could manually transfer songs from one computer to the other using Home Sharing, but what about updated metadata or deleting files?
iCloud has made this situation more interesting. I know iTunes in the Cloud and iTunes Match will keep music files in sync among various devices (including metadata?), but what about podcasts or movies or files not purchased via iTunes? I know there are plenty of details that are yet to be released concerning iCloud, but do you think it will solve this problem entirely, or will manual labor be required to obtain the exact same library among multiple computers?
I have considered only using my iMac to maintain my library, since it is always on and I could use Home Sharing to listen to music on my laptop since they are on the same Wifi network. However, I feel it would be best to keep the same library on two computers for when I take my laptop on vacation away from my home network.
What would you suggest for this situation?
Thanks!

sorry about the slight irrelevence of this post on this thread....i saw this much older post you had in my explorations and it is almost to a "T" my issue currently and i was wondering if you ever came to a conclusion or had any tips or resolution paths i could explore. your original message:
     I have 2 computers I'd like to set up Home Sharing on. One is Windows XP and the other is Windows 7.
     I set it all up but then the libraries never show up. Nothing happens.
     The computers are on the same network and I can successfully share files and a printer. Both computers are      authorized using the same account. Both are signed into that account.
     I don't know why it's not working. Can you please help?
          Thanks!!
is EXACTLY my problem with the only variable being that both of my computers run 7. furthermore, you went on to say you were experiencing issues with the "remote" app. that was the initial objective for me in my system that got me here with a deeper problem with home share. i want to home share my itunes library and control it from my iPod touch 4g. is that such an unreasonable request?!?!? lol. i'm incredibly frustrated and was hoping that since you had such specifically similar circumstances....have you found a solution? PLEASE HELP!!! thank you so much for your time.

Multiple Domain files, Multiple Sites, Publishing Problems

I am frustrated beyond belief. I'm an old hand-coder, coming from BBEdit, but I've been using iWeb almost exclusively since its release, because it really is a great product for quick, easy, stylish designs.
However.... In that year, my collection of sites has grown to 12. Discovering that iWeb becomes a major dog when dealing with that much material, I found and followed the instructions - today - to separate my sites into individual domain files, and edit them individually. iWeb is much snappier and publishing goes much more quickly.
The problem? Well... after editing, "Publish to .Mac" rarely works. Only "Publish All to .Mac" will get the site online (something about an error with the index.html file). But "Publish All to .Mac", I've just discovered, DELETES the other websites that I have previous published. All day I've been doing updates and publishing my sites, only to discover that the uploads have all been wiped out by the most recent one!
I'm a big enough fellow to admit that my knowledge isn't total nor perfect - so please, would someone out there with a better handle on iWeb than I (preferably someone who actually deals with multiple domain files rather than someone who thinks they can guess the problem) please clue me into how we make use of this program non-destructively?
I suppose I could always publish everything to folders and upload it to my iDisk (which itself remains ridiculously slow after how many years now? Sheesh!), but that detracts from the elegance of the .Mac integration, the counter features, - not to mention the little fact that I'm a paying .Mac customer and this darn thing should just work, no?

Mark:
I was where you were also. You should give iWebSites a try. It's to iWeb what iPhoto Library Manager is to iPhoto.
I use iWebSites to manage multiple sites.. It lets me create multiple sites and multiple domain files.
If you have multiple sites in one domain file here's the workflow I used to split them into individual site files with iWebSites. Be sure to make a backup copy of your Domain.sites files before starting the splitting process.
This lets me edit several sites and only republish the one I want. Just remember to put a copy of your current Domain.sites file somewhere else on your HD in case the splitting gets messed up. It went very smoothly for me and I now manage 19 or so sites.
Do you Twango?

How Can I Share iPhoto Library/Keywords Among Multiple Users

Hi there! I am having a bit of a dilemma where I am trying how I can have several users access a shared iPhoto library (as well as retain their own personal iPhoto libraries). Basically, I have a handful of (three) users that need to be able to store/search against a common shared photo library - ideally, in iPhoto.
I understand that I can share albums through iPhoto (users are using a mix of iPhoto '08 and '09) on one account as long as iPhoto is running - a serious drawback. When I tried sharing photos via this method I was able to see the shared albums; however the keywords that were defined for those photos were not available. This presents two questions:
1) Can iPhoto share its library among multiple users (including keywords, etc) so that if a user account (let's call it "media") shares out selected albums that the viewing users (user1 and user2) can search against the keywords in the host library? Or is this not possible with iPhoto?
2) Is there another way of sharing photos that is more efficient and can be hosted on our private servers? The interface in iPhoto is amazing - and if there was an application that allowed for that same sort of feel/tagging we would be good to go...

Well here is the weird thing. If I was sharing out the library from my computer, I could search for the keywords (and obtain results) as expected. However, if I went to another computer that was viewing my shared library, searching by the same keyword did not return any results.

Share files over multiple sites

Hello everybody,
Is there a way to use a single file from multiple sites without having to maintain them twice?
For example I want to use the same PHP-functions in two projects (include file).
Is there a Dreamweaver-technique which allows me to use and upload a file, that is outside of the site-root-directory.
Librarys? Templates?
greeting

Is there a Dreamweaver-technique
Firstly, this has nothing to do with Dreamweaver, so no, there isn't a DW technique. This depends on your webserver and operating system.
The solution also depends on what kind of file you are trying to share, and if the websites are on the save server. HTML/CSS can't normally access files outside the web root, so, for instance, you can't normally share a CSS file between websites (but there is a workaround using aliases). PHP files don't have this limitation, as long as they are on the same server.
I took a quick look at the Google hosted libraries. It looks like it is all javascript. Javascript doesn't have the same limitation that PHP has. For instance, Lots of people reference a remote copy of jQuery in their web pages.
There is a method of sharing files across servers that involves configuring the receiving server to accept the remote file. I experimented with this some years ago but can't find any info on it now. Sorry, I can't even remember what the technique was called. It wasn't easy to get it to work with all browsers as they have different security policies.

Multiple sites, different computers

I have set up multiple websites on my original iMac using iWeb08. I just purchased a MacBook Pro with iWeb09 and would like to do one of two things: 1) Manage all my sites on each computer or 2) Manage "site1" on the MBP and "sites2-4" on the iMac. I am publishing all the sites to my MobileMe account.
It looks like I can copy my original Domain onto a USB Drive and then transfer it to the MBP and edit there. But then I need to make sure I always bring the USB drive back and forth and replace the Domain file each time before I make any changes. Sure that will work, but seems a little annoying and time consuming.
So my question is would it be best to separate the sites into separate Domain files and load them individually from each computer? or just maintain each site on each computer? Can I even publish to MobileMe from two different places like I am thinking?
Thanks for any input!

Do these sites have domain names associated with them?
If you publish multiple sites from separate domain files to the same MMe account the last published site will be the default for any domain name using the CNAME method and will be the default URL for that MMe account: http://web.me.com/YourMMe_AccountName/.
The full URL to each site will work: http://web.me.com/YourMMe_Account_Name/SiteName.
Are those computers linked together on a local network? If so you can just log into the primary computer which houses the domain file from the other computer and work on the domain file. Or, if you have an external HD connected to any of the computers, put the domain file on it and set up access so both computers can reach it.
There is another possible method using DropBox: Old Toad's Tutorial #21 - Managing an iWeb site from multiple Macs with Dropbox.. It's worked for me on a simple site. But one user reported photo pages not getting updated on one computer. It does take a while for the other computer to be updated as it has to be on and connected to the internet. Just proceed with caution till you're sure there's no lagging in the updating.

How do you setup multiple sites to allow for code promotion?

I am somewhat frustrated with the single site flow of the Dreamweaver Site Manager in helping me manage a full development to production code cycle. Ideally I need to have multiple sites managed by Dreamweaver that are just different stages in the code lifecycle. Currently DW only supports local_file -> production. Instead I need (and this is sort of standard for software product systems) to have my local sandbox, a test site, a beta site and a production site.
In the normal dev cycle I would work in my sandbox and have DW synchronize with my test site ( allows scripts that need a full server to be tested in case my local machine is not running a full server ). I can do this today with DW. When I am ready I want be able to have DW synchronize with my beta site (might very well be on a different server via FTP) so that my users/customers can review, test and approve the changes. When everyone has signed off I then want DW to promote this code to the production site.
Now I can do this manually but DW seems to have 95% of the capability in place (mostly the synchronization logic). Is there a way to have it also manage/synchronize the beta and production sites?
Thank You

turingtest, I do have a couple questions.
Number one, does everyone in your family only sych their ipods from only 1 computer? If everyone only uses itunes from 1 computer I can see how that will work. But what if kids want to use itunes for windows? Will "Home Sharing" allow all their music purchased on the MAC, to be also displayed on their itunes for windows laptop? I noticed you have PCs and also an ipad. How do you manage your family's music on these devices?
Also, how did you first get everyone's music library into their own library? Drag & drop? Is the "grouping field" you mentioned under "view", then "view options"? What does this do?
Thanks.
Sorry I missed your post earlier. Normally I follow up on any replies. This one must have fallen off the page on a busy day.
As my kids have left home I have created for them a complete clone of the familiy library, then deleted the tracks from it they don't want. Over time their libraries will divirge, but if needs be they can still update their devices using the library at home. Handy when eldest's kit was stolen.
Grouping is just another property, useful because it isn't generally overwritten by other software but is stored in the tags, so preserved when you copy files from one place to another. You can make the column visible and edit for multiple tracks in Get Info. Some software calls the same field "mood" or "sub-genre". iTunes has a specialist purpose for it generally used with classical music, but it doesn't seem to work very well for that and I don't use it that way.

Multiple sites, publish one at a time?

I have multiple sites, but when I publish them they all publish together. Can I just publish one at a time??? If not, this program is not very good..

I just want to select one SITE and
upload it, not have all the others upload too. Anyway
to get aroud that?
It should not upload a site that has no changes. But there is no way to avoid uploading changes, unless you want to start using separate Users/username/Library/Application Support/iWeb/Domain files for each site.

Noob needs help with hosting multiple sites

Hello I am new to this multi hosting. I have looked on the forum for answers but haven't found any. I am trying to figure out how to host multiple sites. I have my dns working for my default site "example1.com", but need to know if I need to add another dns record for my second site. "example2.com". Also when I point to the new fold that has the second site in it and I assign it port 82 for testing purposes I get an error message saying 403 access forbidden. I need to find out how get permission to view the site for the public. Its in a separate folder on an external hard drive right now for testing purposes. Can any body help me or point me in the right direction? Thanks so much!!!

While what you are telling him is technically functional, it is not correct
I beg to differ, Paul. You are the one that is not correct.
CNAMES have been deprecated as of some years ago
What? huh? really?
Please show me any official document that states this (and not someone who just started a rumor because he didn't understand them). Indeed, the DNS RFC makes no such claim.
{quote}
I stand very much corrected. CNAMEs are not officially deprecated. Interestingly, your post cites precisely what happens when CNAMES used carelessly. How many transactions are needed to resolve Apple's CNAME chain below? RFC1912 (http://www.faqs.org/rfcs/rfc1912.html) has some recommendations that suggests Apple's own network folks have, like me and perhaps even others here, some learning to do. Is that a 'best practice?'
{quote}> Then make sure you tell Apple since this site depends on the use of CNAMEs:
dig discussions.apple.com
discussions.apple.com. 492 IN CNAME discussions.apple.com.edgesuite.net.
discussions.apple.com.edgesuite.net. 4427 IN CNAME a1399.b.akamai.net.
a1399.b.akamai.net. 2 IN A 128.241.220.82
a1399.b.akamai.net. 2 IN A 128.241.220.72
In fact, it uses TWO CNAMES in a chain. Oh my.{quote}
From RFC1912 (which I'm sure many have now read here), section 2.4 is as follows:
{quote}... having chained records such as CNAMEs pointing to CNAMEs may
make administration issues easier, but is known to tickle bugs in
some resolvers that fail to check loops correctly. As a result some
hosts may not be able to resolve such names.{quote}
{quote}> It is not valid to say "don't use these because they could cause problems'. A records can be just as problematic, as can PTRs. Let's not even talk about MX.{quote}
How, exactly, does is an A record problematic? No chains, no additional lookups, no wasted cycles...
We differ here -- and if we are dealing with a newbie, we don't need to enter into unnecessary complexity UNTIL it is a requirement for their solutions.
{quote}> There are many valid reasons to use CNAMEs in DNS, not least of which is the ease of moving a service if it uses CNAMEs. For example, if you have 10 A records all pointing at the same server and you want to migrate to a different machine you have to locate and update all 10 records. If they used a CNAME to the physical server you could move them all at once using a single change. This is especially important in cross-domain links where you may not control all the origin zone files.
{quote}
You're somewhat reaching here, and it is well beyond the scope of the OP's post or needs (well, until they tell us more about their needs, I suppose). There is nothing difficult about 'finding' and updating the necessary records. The final example you gave is a good one and I'll say THAT is an appropriate use of a CNAME, 'though there are other workarounds for it.
Thanks for keeping me honest.

Best Way to Sync Lists Across Multiple Site Collections?

A quick query I'm hoping someone might be able to help me with...
Within our university intranet I am assigning each department a team site within its own Site Collection. So that departments can associate Document Library files with a set list of academic courses, I created a custom dropdown field and deployed it as a Feature. While this worked within SharePoint, when you attempted to set the document properties within the Microsoft Word environment the custom fields were rendered as empty text boxes (meaning that staff are no longer restricted in when information they can enter).
To get around this I'm considering going back-to-basics and creating a Custom List, populating it with the titles of our academic courses, and then assigning it to a Document Library via a Lookup Field. I know that Microsoft Word will then correctly display the metadata dropdown.
As I am using multiple Site Collections, I'm unsure of the "best" way to proceed.
I've already written a Console Application which can create a Custom List within a targetted site and populate it with the contents of an XML file - but I would need to run this every time I created a new Site Collection and what would I do when I wanted to update the contents of all the lists?
Other than modifying my Console Application to loop through all instances of the Custom List within Site Collections and sync it to the contents of the XML file, is there another (better) option that I am over-looking?
Its such a shame I can't create cross-collection Lookup Fields within all of the Site Collections that point to a single top-level list.
Many thanks.

My instinctive questions drifts towards why you have different site collections. If all the sites were sub sites within the same site collection, a global field would solve the issue quite nicely.
If you have legitimate reasons for keeping the sites seperated into separate site collections, I would look at using an Event Handler to trigger updates to reference values in each site collection, be they global fields or lists. Then if you wish to update the values, you only need to update the trigger list to propagate the updates across your site sollections to all your sites in question.
I trust that answers your question...
Thanks

What is the best way to sync multiple collections of contacts among multiple users?

(I originally submitted this question under the "Mac OS X Technologies" section, but got no response. I'm submitting a duplicate here because this is where all the smart folks are! My apologies that my question is only partially related to OS X Server . . . )
What is the best way to sync multiple collections of contacts among multiple users on iOS and OS X?
For example, suppose I have three collections of contacts: Bob's, Sally's, and Common. I want Bob to be able to access and sync Bob's contacts and Common contacts, and Sally to access and sync Sally's contacts and Common contacts. Bob and Sally never need to access or sync each other's contacts. Bob and Sally would both sync and share contacts in Common.
How would I best implement this? It's my understanding I have three options for managing contacts across iOS and OS X: 1. iCloud accounts, 2. Install OS X server, or 3. Install and manage Darwin CardDAV directly. Which method would best support what I wish to do?
I am a seasoned Unix geek well versed in the terminal, so I am prepared to get my hands dirty as much as necessary to achieve what I want. Also, it is sufficient if syncing takes place over WiFi on the local network, in fact, that is desirable versus syncing over the cloud.

Thanks for your reply Nick101. I see my example was oversimplified. When I say "multiple groups of contacts over multiple users" I'm really referring to N groups of contacts over N users.
So I need to add Fred, who can access and sync Bob's contacts, Sally's contacts, and Common contacts, as well as Fred's contacts. Can I do it with OS X server?
You mention you keep your and your partner's contacts administered locally. What keeps you from administering them through OS X server as well?
I am guessing this can all somehow be accomplished with multiple contact accounts, but I can't find any information on the web explicitly describing this.
