I got in charge to create a website based on Java. Production environment specs include Solaris 11.1, OHS 12.1.3, WebLogic 12.1.3, Java 1.7.0_51 and Oracle Database 11.2.
I want to create a server on some cloud or hosting service as Development environment with the same specs to avoid migration problems to Production. I also think this approach helps to give my team a single server where they can work and have some testers/client to visit the site.
Normally I would use a local Development environment but a lot of people is involved and differences with Production can become a problem at migration.
I checked http://www.polarhome.com/ but I don't know if it will fit all specs needed. I looked at Windows Azure and Google Cloud with no success. AWS maybe? I also checked https://cloud.oracle.com but I don't understand if they already offer what I need.
Do you know any providers to create my Development environment or another approach/suggestion to develop this project??
Thanks!
EDIT.
To clarify, the client's Production environment already exists and is running somewhere. My project will be installed on that environment when development is finished. I personally think that developing on any VM with WebLogic 12.1.X and Oracle Database 11.X should be enough, but I've never done it so I wanted to follow client's advise on having a Development environment similar to Production.
Do you think I can just create a VM on any OS and just install WebLogic 12 with Oracle Database 11?? Any suggestions to avoid migration issues if I take that route?
I think that develop a new website from scratch thinking to use the architecture proposed by you is a nonsense. I think that if you will use cloud services like PaaS you will do something better.
In any case, you can find solaris VMs on Cloudsigma , Entic and Oracle Public Cloud

I recently set up a Ubuntu Linux instance in Oracle Cloud. I'm used to take snapshots of VM's so I can roll back if something later goes wrong. In Digitalocean (droplet) this is as simple as pressing a button but in Oracle Cloud I can't seem to find this functionality. I've read documentation and Googled but to no avail. Also seems Oracle have several different cloud offerings with similar naming which makes it hard to find relevant information.
Go to boot volume and create a full backup. This will help you to restore your server to the last good configuration.
Our web developer picked OctoberCMS to develop our new website (his skill). Unfortunately before completion he rapidly left us due to health reasons and is no longer available. His Ubuntu environment has some problems and we need it on CentOS 7 anyway. The rest of us are OctoberCMS newbies, but want to learn it.
We built a CentOS 7 VM and installed OctoberCMS and want to move his work over.
We can not find any instructions on how to "export" the work he has done thus far and import it into our new OctoberCMS.
He is using 10 plugins and 3 he developed. (I don't know if that is relevant)
Is there an easy way to do this or at least instructions?
We have been googling, youtubing, IRC'ing for a week and still at a loss.
Any help would be most appreciated.
There really isn't anything special you need to know about moving an OctoberCMS install to a new server compared to moving over any other PHP application.
I am assuming you know how to do the basics of setting up a LAMP stack, such as setting up a virtual host for the domain you want to host the site on and setting up a MySQL database and user/password to access the database. There are of course many variants on how you could accomplish this such as using a management tool like Plesk or cPanel, or just configuring the services manually via the command line.
1) Ensure your new server is running at least roughly the same version of Apache, MySQL, and PHP.
2) Copy over the directory that contains all of the web files from the old server into the document root for your domain on the new server.
3) Do a database dump from the old server and copy it to the new server. If possible, use the same database name and username and password as the old server. This way you don't have to worry about updating the configuration of the website.
4) Pull up the site and troubleshoot any errors that come up. It is helpful if OctoberCMS debug mode is on.
Following the above method will ensure that you have the exact same setup on your new server that the old server had. This will copy over all of the plugins, data, etc.
There are of course many complexities that can come up during a switch over like this, but this should at least get you started and you can come back to StackOverflow with some more specific hurdles.
Hope that helps.
I am here to get some expert advice on deploying applications to WebLogic Production Server.
Is it a best practice to use Admin Server Console for deploying and redeploying applications in production. Actually I am deploying to a cluster having two managed server instances.
I have encountered this issue while i am redeploying application in the production. When i am deleting existing .ear file and adding updated .ear file will put the updated .ear file into prepared state. I can not make it Active state using Admin Server Console. If i try it will through some exceptions. But after some time it automatically goes in to active state, but i don't know what is happening inside. Sometimes i restart the server to make it active. Could anybody explain me what is the procedure when deploying application and redeploying applications in weblogic
Thanks in advance for any Help...
Generally WLST (WebLogic Scripting Tool) is used to deploy the applications. Administration Console can also be used to deploy/upgrade the applications but if there are many environments that need to be upgraded then WLST (which works like a command line tool) is much better option.
Get an overview of WLST to know how to use it to deploy/undeploy/upgrade applications.
Check out "Understanding WebLogic Server Deployment" and the "Redeploying Applications in a Production Environment". There are different factors that affect redeployment of an application which you might be running into.

Additionally, there is a WebLogic Plug-in for Maven in more recent WebLogic releases that you can use for deployments in conjunction with Maven.
I installed a java web service on a machine that accesses an Oracle DB via JDBC on the same network. The service was functioning fine for several months until this morning when I installed another applicaiton that access the database using ODP.NET. I'm trying to figure out what went wronge to cause the ORA-01017 exceptions that I'm getting. This generally means that the login credentials are invalid, but the login credentials haven't changed. I also verified it the service's log4j output that it is indeed still trying to connect to the DB correctly.
I realize I don't have much to go off of here, but I'm trying to figure out what other dependencies that. The web service came packaged with ojdbc14.jar, so that tells me that it targets java1.4, but presumably would work fine in later java versions. Not too sure about it working with later java versions, however, it was working fine until today.
Does OJDBC rely on tnsnames.ora. If it depends on how the service uses OJDBC, then I'm not sure which it is doing. I suppose it's possible I deleted the tnsnames.ora, but that is a bit of a longshot. I also tried manging Apache Tomcat (running on Win Server 2003 x64) to target different java jvm versions, but to no avail. It was initially targeting the default jvm.
Are there other dependencies that I've missed here, or any diagnostic measures I could try? THe same web service is running on another machine on the same network which I am pretty sure is configured exactly the same. Again, it was working on both machines until today, and is now just working on the one.
Tomcat targets JDK 7.
Looks like replacing ojdbc14.jar with ojdbc6_g.jar did the trick. No idea why it was the case only for 1 of the 2 machines. ojdbc6 targets JDK 6, but ojdbc14 did, and should have continued to work. If anyone has any additional insight here, let me know.
My office is growing and ive been tasked to build out the IT for our web development.
Whats the best tool/setup for doing web development in a group setting? The requirements are a centralized code repository, a location to test development code on, and finally a way to push tagged code out to a staging server. What im thinking is svn/redmine for code repo, each user has an account on a central development machine to allow for ssh access(eclipse over ssh) and their own virtual host on the dev server which gives everyone a centralized development sandbox. Code is written and tested on this dev box then checked back into svn and later tagged and pushed out to the staging server. Yeah? Thoughts comments or recommendations?
*Also, in a dev environment what is the best way to handle databases? Is it wise to pull from the production database? Also should each developer have his/her own db or work off a master db?
**We are building a magento application and also have some custom backoffice tools that run on cakePHP.
Although this subject is off-topic in StackOverflow and flagged so then you need to concentrate on following areas:
VERSION-CONTROL
GIT has all the glory and you don't need your own box for this as https://bitbucket.org/ offers unlimited data and private/public repos and you can set your codebase there. http://github.com is also powerful and de facto most popular version-control oriented tool out there although it comes for a small price
so your master branches live in your version control and your devs will checkout frpom there and commit to it as well
your deployment tools will deploy data to your live and staging environments from your master
ENVIRONMENTS
usually three are used LIVE, STAGE, DEV
LIVE is well live and only approved code gets deployed there
STAGE is pre-live environment and should be exact replica environment according to LIVE so all things can be tested there by merchant
DEV is cool to have exact replica but can as well be on developers local env and is ment for loose testing and experimenting
DATABASES AND DEPLOYMENT
mysql databases are pain in the ass to sync so you better have a script for it that syncs from live to others and prevent syncing from other environments to LIVE. This limitation also requires that all the configuration and content will be added from LIVE only and only then synced down the line. Every change to schema or permanent setting should be handled by update scripts (As we are talking MAGENTO CE , MAGENTO EE has migration built in)
for deployment I also suggest you to build a fabric or capistrano script that resets dev and staging environments, handles database reset and pull from LIVE DB, and imports code from central repository.
it's also a good idea to target the following everyday tasks:
clients needs to reset the stage for it's tests
project manager, developer or testers need to test so spawning a test clone should be oneclick action (take current db and code and make it live in some subfolder for specific test only) as well as deleting the test
3rd party devs might need access to specific test or dev environment (this is actual with magento as in average there are at least 10 external extensions installed in every magento store)
