• TFS 2012 Upgrade and SQL Server - SharePoint - OS Requirements.

  - by Vishal

  Hello folks,Recently I was involved in Installation and Configuration of Team Foundation Server 2010 Farm for a client. A month after the installation and configuration was done and everything was working as it was supposed to, Microsoft released Team Foundation Server 2012 in mid August 2012. Well the company was using Borland Starteam as their source control and once starting to use TFS 2010, their developers and project managers were loving it since TFS is not just a source control tool and way much better then StarTeam. Anyways, long story short, they are now interested in thinking of upgrading to the newest version. Below are some basic Hardware and Software requirements for TFS 2012:Operating System:Windows Server 2008 with SP2 (only 64bit)Windows Server 2008 R2 with SP1 (only 64bit)Windows Server 2012 (only 64bit)SQL Server:SQL Server 2008 R2 and SQL Server 2012SQL Server 2008 is no longer supported.SQL Server Requirements for TFS.SharePoint Products:SharePoint Server 2010. (SharePoint Foundation 2010, Standard, Enterprise).MOSS 2007 (Standard, Enterprise)Windows SharePoint Services 3.0 (WSS 3.0)SharePoint Products Requirements for TFS.Project Server:Project Server 2010 with SP1.Project Server 2007 with SP2.Project Server Requirements for TFS.More information onf TFS Upgrade Requirements can be found here. Hardware Recommendations can be found here.Thanks,Vishal Mody

• Opinions on logging in multiprocess applications

  - by chkorn

  We have written an application that spawns at least 9 parallel processes. All processes generate a lot of logging information. Currently we are using Pythons QueueHandler to consolidate all logs into one file. Unfortunately this sometimes results in very messy files which make them hard to read (e.g. Track what exactly is going on in one thread). Do you think it is a viable option to separate all messages into dedicated files, or is this going to make things even more messy due to the high number of files? What are your general experiences when writing log files for multiprocessed/multithreaded applications?

• cPanel email doesn't seem to work - error 550?

  - by Megh

  I am fairly new to the web hosting game, so bear with me :) Recently set up a VPS with cPanel and WHM. Everything is going well so far, I've created a user domain and transferred my website there, managed a couple of databases with phpmyadmin, everything was going great until I started messing around with email. I made an email account [email protected] through cPanel, although when I try and email this address I get the following error: Technical details of permanent failure: Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 550 550 Unknown user (state 13) Quite unsure of what to do next, in all honesty.

• SQL Server 2008 Service Pack 1 and the Invoke or BeginInvoke cannot be called error message

  - by Jeff Widmer

  When trying to install SQL Server 2008 Service Pack 1 to a SQL Server 2008 instance that is running on a virtual machine, the installer will start:   But then after about 20 seconds I receive the following error message: TITLE: SQL Server Setup failure. ----------------------------- SQL Server Setup has encountered the following error: Invoke or BeginInvoke cannot be called on a control until the window handle has been created. ------------------------------ BUTTONS: OK ------------------------------ Searching for this issue I found that several people have the same problem and there is no clear solution.  Some had success with closing windows or Internet Explorer but that didn’t work for me; what did work is to make sure the SQL Server 2008 “Please wait while SQL Server 2008 Setup processes the current operation.” dialog is selected and has the focus when it first shows up.  Selected (with the current focus) it looks like this:   Without focus the dialog looks like this: Add a comment if you find out any information about how to consistently get around this issue or why it is happening in the first place.

• SEO indexing with dynamic titles, keywords and description

  - by Andrea Turri

  I'm working on a worldwide website (all in one single domain) so I'm wondering to create dynamic titles, descriptions, keywords and headings for each location. What I'm doing is to get information from the IP of the user and show for example a dynamic title: var userCity = codeToGetCityFromIP; <title>Welcome to userCity</title> // and same for description, keywords and headings... Obviously the code is different... I'd like to know if it is a good solution to create multiple SEO indexing based on cities? I'm also using GeoLocation and I do same using the returned values from it. I'm doing right or there are more effective ways to indexing in different countries and cities without create multiple website for each city of the world? Thanks.

• Using JPA 2.0 with WebLogic Server 10.3.4 and Eclipse

  - by greg.stachnick

  Beginning in Oracle Enterprise Pack for Eclipse (OEPE) 11.1.1.6.1, we introduced a new feature for WebLogic Server configuration called Server Extensions. Similar in concept to project facets, Server Extensions allow us to install additional technologies, libraries, configurations, etc into an existing server runtime. WebLogic Server 10.3.4 introduces new support for Java Persistence 2.0, the new JEE 6 standard entity access. In order to start developing JPA 2.0 applications with WebLogic Server 10.3.4, a SmartUpdate patch must be applied to add and configure the EclipseLink libraries. More information on the manual EclipseLink installation and configuration can be found here. OEPE provides a Server Extension for JPA 2.0, making the addition and configuration of JPA 2.0 and EclipseLink much easier. When defining a new WebLogic Server 10.3.4 configuration, simply click the Install link for Java Persistence 2.0 and OEPE will take care of the WebLogic Server enablement for JPA 2.0.

• TypeScript Resources

  - by csmith18119

  TypeScript looks like a great start to evolving javascript.  I am going to start playing with it seeing what it is like.  This is the post I will update will all the resources I've found. Welcome to TypeScript - The TypeScript Language has an offical site, and this is it. This site does a nice job of giving the key information about the language and its uses, as well as highlighting that it is an open source project, which is cross platform. TypeScript is still causing quite a buzz in the community, here are some more of peoples initial impressions: Introducing TypeScript - Rob Eisenberg Why does TypeScript have to be the answer to anything? - Scott Hanselman TypeScript (or the obligatory post about it) - Shawn Wildermuth TypeScript project in Visual Studio 2012 - Linvi Microsoft TypeScript : A quick introduction and A Love Affair Begins here. - Anoop Madhusudanan Microsoft TypeScript : A Typed Superset of JavaScript & Using TypeScript in ASP.NET MVC Projects - Shiju Varghese Hello TypeScript - Getting Started - Sumit Maitra

• How can I implement a Epub Reader in Javascript

  - by Vlad Nicula

  I'm wondering if I can create a epub reader in javascript. The basic requirements would be: 1) Server parts of the epub reader from a server API. 2) Read the EPUB data in javascript. 3) Render it on page. 4) Provide some extra functionality, like text highlights or page notes. I have no information about how I could do this. I'm willing to try a prototype project. What are the steps that I could take towards implementing such a thing?

• HSSFS Part 3: SQL Saturday is Awesome! And DEFAULT_DOMAIN(), and how I found it

  - by Most Valuable Yak (Rob Volk)

  Just a quick post I should've done yesterday but I was recovering from SQL Saturday #48 in Columbia, SC, where I went to some really excellent sessions by some very smart experts.  If you have not yet attended a SQL Saturday, or its been more than 1 month since you last did, SIGN UP NOW! While searching the OBJECT_DEFINITION() of SQL Server system procedures I stumbled across the DEFAULT_DOMAIN() function in xp_grantlogin and xp_revokelogin.  I couldn't find any information on it in Books Online, and it's a very simple, self-explanatory function, but it could be useful if you work in a multi-domain environment.  It's also the kind of neat thing you can find by using this query: SELECT OBJECT_SCHEMA_NAME([object_id]) object_schema, name FROM sys.all_objects WHERE OBJECT_DEFINITION([object_id]) LIKE '%()%'  ORDER BY 1,2 I'll post some elaborations and enhancements to this query in a later post, but it will get you started exploring the functional SQL Server sea. UPDATE: I goofed earlier and said SQL Saturday #46 was in Columbia. It's actually SQL Saturday #48, and SQL Saturday #46 was in Raleigh, NC.

• Calculating instantaneous speed and acceleration for a simple Car software model

  - by Dylan

  I am trying to model a speedometer and tachometer for a simple software model of a car dashboard. I want this to be relatively simple, so for my purposes I won't likely simulate variables such as drag (or, assume that drag is a constant). But I would like to know the general formulas for: 1) Calculating the RPM, depending on a position of a graphical slider representing the accelerator. 2) Using this information to find the instantaneous speed (or, magnitude of instantaneous velocity?). I am not sure, in the case of 2), what other independent variables I need to consider. Do I need to consider the frequency of rotation of the wheels (assuming a fixed radius), in addition to the RPM? If anyone can give me a rough explanation plus relevant formulas, or alternatively direct me to other trusted resources online (I have had a hard time sifting through info and determining the accuracy), it would be much appreciated.

• How did Ubuntu know my WPA Key?

  - by nebukadnezzar

  I've recently moved my /home to another computer (keeping all configuration files), with a fresh installation of Ubuntu 10.10. After Installation I've installed wicd and ndiswrapper, to get my Internet Connection up and running. However, after changing /etc/network/interfaces from auto lo iface lo inet loopback To auto wlan0 iface wlan0 inet dhcp and running sudo /etc/init.d/networking restart to get wlan0 set up, wicd just suddenly connected... to my modem. Without supplying any information about the modem whatsoever. Of course wicd creates a local directory at ~/.wicd/, but that directory is empty, and the temporary global configuration at /var/lib/wicd/configurations/ didn't exist due to fresh installation of ubuntu. So what's the deal? Where did wicd get the ESSID and the WPA Key? There hasn't been any activity in this question, but it's still open (and even worth some rep)!

• Removing existing filtered pages from Google's index: noindex / 301 / canonical to non-filtered page?

  - by Noam

  I've decided to remove some of my site's pages from the Google index to focus more of the indexed pages on higher quality pages. The pages I'm going to remove are already in the index. These removed pages are filtered pages which will continue to exist, I just don't want them in the google index because they add little quality to the same page without any filter selected. I've added in webmaster tools specification of narrow for the parameters that set these filters, but it doesn't seem this changes anything in how he handles these pages. So I'm considering three options: Adding <meta name="robots" content="noindex" /> to the html header of these filtered pages 301 to the non-filtered page that contains the most similar information and will remain in the index Canonical tag. Which I'm not sure is exactly the mainstream use case, as these aren't really the same pages. Which should I use?

• ZeroBin Is an Encrypted PasteBin Alternative

  - by Jason Fitzpatrick

  ZeroBin is like the heavily armored sibling of PasteBin; You can still paste large chunks of text but that text is encrypted with client-side encryption. PasteBin is great when you need to share snippets of code or log files, the only problem is the service is essentially wide open. Not such a big deal if you’re sharing your XBMC logs on the support forum to get a little help figuring out why your movie list won’t update, but less than idea if you’re sharing more sensitive information. ZeroBin steps in to fill that gap by offering client-side encryption where ZeroBin has no knowledge of the content of your shared text snippets. In addition you can set up the ZeroBin content to self destruct after a set amount of time. Hit up the link below to take ZeroBin for a spin.

• Twig Code Completion

  - by Ondrej Brejla

  Hi all! After few weeks we have a new feature for you which will be available in upcoming NetBeans 7.3. It's about new code completion in Twig files! So let us introduce it a bit. Now we hopefully support all of Twig built-in elements. It means Tags, Filters, Functions, Tests and Operators (see Twig documentation for more information). All elements are also documented, so if you don't know what which element does, just read it in the IDE documentation window! We try to resolve some Completion Context to suggest you only the most corresponding element types, but it's not so visible, since almost everything can be used everywhere in Twig files ;) And that's all for today and as usual, please test it and if you find something strange, don't hesitate to file a new issue (product php, component Twig). Thanks a lot!

• The Arab HEUG is now a reality, and other random thoughts

  - by user9147039

  I just returned from Doha, Qatar where the first of its kind HEUG (Higher Education User Group) meeting for institutions in the Middle East and North Africa was held at Qatar University and jointly hosted by Damman University from Saudi Arabia. Over 80 delegates attended including representation from education institutions in Oman, Saudi Arabia, Lebanon, and Qatar. There are many other regional HEUG organizations in place (in Australia/New Zealand, APAC, EMEA, as well as smaller regional HEUG’s in the Netherlands, South Africa, and in regions of the US), but it was truly an accomplishment to see this Middle East/North Africa group organize and launch their chapter with a meeting of this quality. To be known as the Arab HEUG going forward, I am excited about the prospects for sharing between the institutions and for the growth of Oracle solutions in the region. In particular the hosts for the event (Qatar University) did a masterful job with logistics and organization, and the quality of the event was a testament to their capabilities. Among the more interesting and enlightening presentations I attended were one from Dammam University on the lessons learned from their implementation of Campus Solutions and transition off of Banner, as well as the use by Qatar University E-business Suite for grants management (both pre-and post-award). The most notable fact coming from this latter presentation was the fit (89%) of e-Business Suite Grants to the university’s requirements. In a few weeks time we will be convening the 5th meeting of the Oracle Education & Research Industry Strategy Council in Redwood Shores (5th since my advent into my current role). The main topics of discussion will be around our Higher Education Applications Strategy for the future (including cloud approaches to ERP (HCM, Finance, and Student Information Systems), how some cases studies on the benefits of leveraging delivered functionality and extensibility in the software (versus customization). On the second day of the event we will turn our attention to Oracle in Research and also budgeting and planning in higher education. Both of these sessions will include significant participation from council members in the form of panel discussions. Our EVP’s for Systems (John Fowler) and for Global Cloud Services and North America application sales (Joanne Olson) will join us for the discussion. I recently read a couple of articles that were surprising to me. The first was from Inside Higher Ed on October 15 entitled, “As colleges prepare for major software upgrades, Kuali tries to woo them from corporate vendors.” It continues to disappointment that after all this time we are still debating whether it is better to build enterprise software through open or community source initiatives when fully functional, flexible, supported, and widely adopted options exist in the marketplace. Over a decade or more ago when these solutions were relatively immature and there was a great deal of turnover in the market I could appreciate the initiatives like Kuali. But let’s not kid ourselves – the real objective of this movement is to counter a perceived predatory commercial software industry. Again, when commercial solutions are deployed as written without significant customization, and standard business processes are adopted, the cost of these solutions (relative to the value delivered) is quite low, and certain much lower than the massive investment (and risk) in in-house developers to support a bespoke community source system. In this era of cost pressures in education and the need to refocus resources on teaching, learning, and research, I believe it’s bordering on irresponsible to continue to pursue open-source ERP. Many of the adopter’s total costs are staggering and have little to show for their efforts and expended resources. The second article was recently in the Chronicle of Higher Education and was entitled “’Big Data’ Is Bunk, Obama Campaign’s Tech Guru Tells University Leaders.” This one was so outrageous I almost don’t want to legitimize it by referencing it here. In the article the writer relays statements made by Harper Reed, President Obama’s former CTO for his 2012 re-election campaign, that big data solutions in education have no relevance and are akin to snake oil. He goes on to state that while he’s a fan of data-driven decision making in education, most of the necessary analysis can be accomplished in Excel spreadsheets. Yeah… right. This is exactly what ails education (higher education in particular). Dozens of shadow and siloed systems running on spreadsheets with limited-to-no enterprise wide initiatives to harness the data-rich environment that is a higher ed institution and transform the data into useable information. I’ll grant Mr. Reed that “Big Data” is overused and hackneyed, but imperatives like improving student success in higher education are classic big data problems that data-mining and predictive analytics can address. Further, higher ed need to be producing a massive amount more data scientists and analysts than are currently in the pipeline, to further this discipline and application of these tools to many many other problems across multiple industries.

• How to access values of dynamically created TextBoxes

  - by SAMIR BHOGAYTA

  If one adds controls dynamically to a page and wants to get their information after PostBack, one needs to recreate these elements after the PostBack. Let's consider the following idea: First you create some controls: for(int i=0;i TextBox objBox = new TextBox(); objBox.ID = "objBox" + i.ToString(); this.Page.Controls.Add(objBox); } After PostBack, you want to retrieve the text entered in the third TextBox. If you try this: String strText = objBox2.Text; you'll receive an exception. Why? Because the boxes have not been created again and the local variable objBox2 simply not exists. How to retrieve the Box? You'll need to recreate the box by using the code above. Then, you may try to get its value by using the following code: TextBox objBox2; objBox2 = this.Page.FindControl("objBox2") as TextBox; if(objBox2 != null) Response.Write(objBox2.Text);

• Can Kind People Finish First?

  - by Oracle Accelerate for Midsize Companies

  by Jim Lein, Oracle Midsize Programs In an earlier post, I expressed my undying love for KIND Snacks' products. This month's Oracle Profit magazine features an interview with KIND Healthy Snacks Founder and CEO Daniel Lubetzky entitled "Better Business". Lubetzky expresses his vision for making KIND a "not for profit only" company.  All great companies start with a good idea. In this case, that one great idea was to offer a healthy snack with ingredients you can "see and pronounce". That's one of things I really like about this company--that coupled with the fact that their snacks taste great. They compete in an over crowded playing field but I've found that it's rare to find an energy snack that both tastes good and is good for you.  A couple of interesting facts I learned from reading this article: Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin-top:0in; mso-para-margin-right:0in; mso-para-margin-bottom:10.0pt; mso-para-margin-left:0in; line-height:115%; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin;} 9 out of 10 consumers who try a KIND bar will purchase a KIND product again and recommend it to others KIND has the highest Net Promoter Score among the top 10 brands in the nutritional bar category (I confess I've never heard about this rating before but now that I have it's pretty cool) KIND's coporate mantra, "Do the Kind Thing" both encourages people to do random acts of kindness and provides easy mechanisms for doing so. Not coincidentally, I think, KIND is indeed a story about how nice guys can finish first. KIND has doubled in size every year for the last ten  years and now employees over 300 people, with sales exceeding $120M annually. Growth Applies Pressures One thing I know for certain from interacting our with fast growing customers over the last fifteen years is that growth applies myriad pressures across the organization--resources, processes, technology systems, and leadership agility. And it's easy to forget that Oracle was once an entrepreneurial startup and experienced all those same pressures that other growing companies are experiencing today. When asked by Profit Editor in Chief Aaron Lazenby, " What sort of pressure does KIND"s growth and success place on operations?", Lubetzky responded, "We have a demand planning process right now that is manual to a significant extent, and it just takes so much management time. It takes us days and sometimes weeks to produce information that is critical to our business—and by the time we get the results, we need revised data. Our sales leadership could go out selling, but instead they’re talking to our team about forecasts." Hitching Your Wagon to Oracle Lubetzky and his team selected Oracle for what I believe is our company's greatest strength: hitch your wagon to Oracle and you can trust that we will be there for the long run with the solutions you need and financial staying power. In Lubetzky's words, "The KIND philosophy requires you to have a long-term view of things; taking shortcuts may be the fastest way to get things done, but in the long term that can come back and bite you. Oracle is the type of company—and has the kind of platform—that is here for the long term. It’s not going to go away tomorrow. And Oracle is going to invest all the necessary resources into staying ahead of the game and improving." o next time you're in the supermarket or an REI (my favorite store in the world) or any of the other 80,000 locations that carry KIND, give one a try. Maybe some day you'll want to become a KIND Brand Ambassador.   Looking for more news and information about Oracle Solutions for Midsize Companies?

• What is a generalized form creator that runs on .NET / Windows?

  - by Josh

  At the institution that I'm at, we've been looking for web applications that enable users to create and deploy their own forms. Similar applications are Wufoo, and google forms. Unfortunately, those solutions will not work for us, because we are required to host all data and information on our own servers. I've found a few solutions that are written in PHP, but at this point, it doesn't appear that this is acceptable. I've tried searching for ".net form creator" but unfortunately, when you search for ".net forms" you get a lot of results relating to created asp.net webforms, which is not what we're looking for at all. I've been told that finding a solution that runs on .NET and windows servers with either Oracle or MSSQL databases would be much more acceptable. I've found a few, but they are open source, and the IS Security people are not kind to those solutions, despite my attempts to show otherwise. If anyone knows of some solution out there, I would greatly appreciate you passing on the names of those applications!

• WebLogic JDBC Use of Oracle Wallet for SSL

  - by Steve Felts

  Introduction Secure Sockets Layer (SSL) can be used to secure the connection between the middle tier “client”, WebLogic Server (WLS) in this case, and the Oracle database server.  Data between WLS and database can be encrypted.  The server can be authenticated so you have proof that the database can be trusted by validating a certificate from the server.  The client can be authenticated so that the database only accepts connections from clients that it trusts. Similar to the discussion in an earlier article about using the Oracle wallet for database credentials, the Oracle wallet can also be used with SSL to store the keys and certificates.  By using it correctly, clear text passwords can be eliminated from the JDBC configuration and client/server configuration can be simplified by sharing the wallet across multiple datasources. There is a very good Oracle Technical White Paper on using SSL with the Oracle thin driver at http://www.oracle.com/technetwork/database/enterprise-edition/wp-oracle-jdbc-thin-ssl-130128.pdf [LINK1].  The link http://www.oracle.com/technetwork/middleware/weblogic/index-087556.html [LINK2] describes how to use WebLogic Server with Oracle JDBC Driver SSL. The information in this article is a guide on what steps need to be taken in the variety of available options; use the links above for details. SSL from the driver to the database server is basically turned on by specifying a protocol of “tcps” in the URL.  However, there is a fair amount of setup needed.  Also remember that there is an overhead in performance. Creating the wallets The common use cases are 1. “data encryption and server-only authentication”, requiring just a trust store, or 2. “data encryption and authentication of both tiers” (client and server), requiring a trust store and a key store. It is recommended to use the auto-login wallet type so that clear text passwords are not needed in the datasource configuration to open the wallet.  The store type for an auto-login wallet is “SSO” (Single Sign On), not “JKS” or “PKCS12” as in [LINK2].  The file name is “cwallet.sso”. Wallets are created using the orapki tool.  They need to be created based on the usage (encryption and/or authentication).  This is discussed in detail in [LINK1] in Appendix B or in the Advanced Security Administrator’s Guide of the Database documentation. Database Server Configuration It is necessary to update the sqlnet.ora and listener.ora files with the directory location of the wallet using WALLET_LOCATION.  These files also indicate whether or not SSL_CLIENT_AUTHENTICATION is being used (true or false). The Oracle Listener must also be configured to use the TCPS protocol.  The recommended port is 2484. LISTENER = (ADDRESS_LIST= (ADDRESS=(PROTOCOL=tcps)(HOST=servername)(PORT=2484))) WebLogic Server Classpath The WebLogic Server CLASSPATH must have three additional security files. The files that need to be added to the WLS CLASSPATH are $MW_HOME/modules/com.oracle.osdt_cert_1.0.0.0.jar $MW_HOME/modules/com.oracle.osdt_core_1.0.0.0.jar $MW_HOME/modules/com.oracle.oraclepki_1.0.0.0.jar One way to do this is to add them to PRE_CLASSPATH environment variable for use with the standard WebLogic scripts. Setting the Oracle Security Provider It’s necessary to enable the Oracle PKI provider on the client side.  This can either be done statically by updating the java.security file under the JRE or dynamically by setting it in a WLS startup class using java.security.Security.insertProviderAt(new oracle.security.pki.OraclePKIProvider (), 3); See the full example of the startup class in [LINK2]. Datasource Configuration When creating a WLS datasource, set the PROTOCOL in the URL to tcps as in the following. jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS=(PROTOCOL=tcps)(HOST=host)(PORT=port))(CONNECT_DATA=(SERVICE_NAME=myservice))) For encryption and server authentication, use the datasource connection properties: - javax.net.ssl.trustStore=location of wallet file on the client - javax.net.ssl.trustStoreType=”SSO” For client authentication, use the datasource connection properties: - javax.net.ssl.keyStore=location of wallet file on the client - javax.net.ssl.keyStoreType=”SSO” Note that the driver connection properties for the wallet require a file name, not a directory name. Active GridLink ONS over SSL For completeness, there is another SSL usage for WLS datasources.  The communication with the Oracle Notification Service (ONS) for load balancing information and node up/down events can use SSL also. Create an auto-login wallet and use the wallet on the client and server.  The following is a sample sequence to create a test wallet for use with ONS. orapki wallet create -wallet ons -auto_login -pwd ONS_Wallet orapki wallet add -wallet ons -dn "CN=ons_test,C=US" -keysize 1024 -self_signed -validity 9999 -pwd ONS_Wallet orapki wallet export -wallet ons -dn "CN=ons_test,C=US" -cert ons/cert.txt -pwd ONS_Wallet On the database server side, it’s necessary to define the walletfile directory in the file $CRS_HOME/opmn/conf/ons.config and run onsctl stop/start. When configuring an Active GridLink datasource, the connection to the ONS must be defined.  In addition to the host and port, the wallet file directory must be specified.  By not giving a password, a SSO wallet is assumed. Summary To use SSL with the Oracle thin driver without any clear text passwords, use an SSO Oracle Wallet.  SSL support in the Oracle thin driver is available starting in 10g Release 2.
