I have the IBM Business Process Manager Advanced 7.5 installed.
Question:
Is it possible to install and run newer version - IBM BPM 8.5 on the same machine?
I worry about ports conflict (for example port 9043 to IBM Console).
Maybe I should ask how to change default port configuration?
Please help.
Technically it can be possible, however I suggest you do not do this as ibm bpm requires a lot of system resources to run and installing two versions of ibm bpm can make the system slower than ever before.
However I have seen multiple instances of same ibm bpm version running on a single cluster on server VM. This is practically stable and in use from considerable tenure.
PS. - I had administered a huge ibm bpm infra containing 80+ ibm bpm servers.
As Gas already commented, in theory this is possible. But you have to be aware, that IBM BPM is not only using the specified ports for web access, it also uses ports for internal communication. In my opinion, this is not an easy task to get right.
On the other hand, the system requirements for IBM BPM are quite challenging for the server, if You want to run both instances in parallel, you should consider that your server will need to be capable. WebSphere is kind of greedy and not really designed to share its resources ;)
Yes, you can run multiple versions of BPM on the same system. The primary concerns are going to be port conflict and OS system resources. Use the BPMConfig to create a new profile and installation that is on different ports. On my lab machines with VMs, I install all the BPM installs with the default ports and only have one (1) running at a time. If I need 2, I just spin up a new VM from the base template and go from there.
By Default, the port conflicts are addressed by the WebSphere Application server code. If needed you can specify "initialPortAssignment" for Dmgr, node and cluster members while creating the environment using BPMConfig command. You can even specify specific port numbers using the
https://www.ibm.com/support/knowledgecenter/en/SSFPJS_8.6.0/com.ibm.wbpm.ref.doc/topics/samplecfgprops.html
You can also provide Websphere options like "-startingPort starting_port | -portsFile ports_file_path | -defaultPorts" for Dmgr bpm.dmgr.profileOptions= and nodes bpm.de.node.#.profileOptions in the BPMConfig properties file. For cluster members just have option to indicate the starting port.
REf: https://www.ibm.com/support/knowledgecenter/cs/SSAW57_8.5.5/com.ibm.websphere.nd.multiplatform.doc/ae/rxml_manageprofiles.html
I would not advise on changing the port numbers once you start using the BPM environment.
As indicated by others make sure you have enough resources if you are planning to run both environments at the same time.
Yes, I am using two versions for evaluation. Port conflicts can be handled using server (WebSphere Integrated Solutions Console) console or BPMConfig utils.

We have one existing vmware virtualization contains 4 host, each host contains nearly 6vms, Now we are planning to deploy Open stack, The thing which Open stack version is good to deploy in VM, i have installed Centos 7 on VM.
I have to confirm which version of open stack is good for real time environment.
If anyone knows pls suggest version, and installation URl it will much better understanding to me,
Get started with devstack which is easier to install as you just have to run one script(stack.sh) and it will deploy all the clients on same machine. You can use that to practice creating VMs, making security groups and assigning floating ip to the vms. After that try to configure on a multinode architecture and I would suggest that you get a Ravello account (https://www.ravellosystems.com/) for that instead of using your own servers. This link might help you in configuration (https://docs.oracle.com/cd/E36784_01/html/E54155/archover.html#scrolltoc).
Search "openstack multinode deployment" on google. You will have plenty of links.
With OpenStack's architecture, is it possible to, for instance, have a PowerPC64 (Altivec) machine, a Intel CoreDuo machine, and a ARMv6 all on the same cluster?
Or is this impossible, because of the restrictions in building buildpacks when deploying to multiple architectures?
EDIT: Whoops, I meant OpenStack, not OpenShift ;)
The answer above is correct (answer from developercorey).
Although whether this suits you depends on how its managed and what your trying to achieve. Typically when you add servers with different physical attributes such as CPU, Disk, Network cards etc you group them into different host aggregates.
By default when you launch a VM it will try and find a suitable host, but you can also tag it, so for example if your VM required alot of disk IO, you might want to place it on a host that has SSD drivers. So you can put those hosts into a 'SSD' aggregate, and then when launching your VM you can make sure it goes to a host in that aggregate.
If your just trying to make the most out of the hardware you have, then I don't see any issue by mixing them.
I don't think that they have to be, but I do believe that they only build packages for 1 or 2 architechtures, so I'm not sure how many options you really have there.
I have been looking to use Storm which is available with Hortonworks 2.1 installation but in order to avoid installing Hortonworks in addition to a Cloudera installation (which has Spark in it), I tried to find a way to use Storm in Cloudera.
If one can use both Storm and Spark on a single platform then it will save additional resources required to have both Cloudera and Hortonworks installations on a machine.
You can use storm with Cloudera installation. You will have to install it on your own and maintain it as such. It will not be part of the Cloudera stack but that should not stop you from using it along with Hadoop if you need it.
You can use Storm on any of the vendor platform. However, storm cluster management is something you have to consider. Storm is not part of the CDH distribution. Cloudera Manager does not manage the lifecycle of the storm services and configurations, nor does it monitor the storm cluster, unless you are willing to write a Clouderea Manager extension yourself. On the contrary, if you choose a vendor such as HDP, the Ambari management tool on HDP provides all the above management features.
If you have a streaming project on CDH, you should strongly consider Apache Spark first, as it provides the same programming model for both batch and streaming processing. You do not need to learn a new API. However, Apache Spark streaming is micro-batch. Thus in use cases that requires sub-second low latency real-time processing, Storm is more suitable.
You can use Storm alongside Cloudera.
All the above are true, but why would you?
Spark includes Spark Streaming, which allows you to handle data processing and stream/event processing workloads using a single API. Spark/Streaming is already inside CDH.
So, why burden yourself with two different APIs?
You can install Apache Storm on Cloudera VM.
For a basic setup and test run, follow below link:
https://github.com/vrmorusu/StormOnClouderaVM/wiki/Apache-Storm-on-Cloudera-VM
This should get you started on developing Storm applications on Cloudera VM.
Need help on 3 aspects of Cloudstack. It has become the major point of our decision to go ahead with the implementation
Serial port debugging:
We do lot of serial port kernel debugging in Windows and UNIX. There is no out of box support for it . We need to go to VMWARE level to enable it , and we want to shield users from this. Any suggestions on this front.
Memory Snapshoting
People here are used for VMWare memory snapshoting feature. Also the ease with which Workstation/vSphere manages the Snapshots. Is there any way we can use that in Cloudstack? Our implementation is on VMWare , so we already have things in place , so just want to know , how to get it integrated with Cloudstack.
VMWare Tools
Whenever we create an instance from ISO's , we see that Mouse do not work. It is really painful to install the VMWare tools and get the mouse working. Is there any solution for this problem.
Need immediate feedback on Apache CloudStack?
Send your question to the mailing list
Need specific features to be added?
Talk to support Vendor such as Citrix.
Serial port debugging: -- What Steps you follow in enabling it in vmware
Memory Snapshoting: -- Cloudstack provides the snapshot feature ,but after taking snapshot you can not create vm from that snapshot,first you will have to convert that snapshot in templates and then you can create vm
VMWare Tools -- You can use attach iso facility of cloudstack .Initially install operating system with tabs but after installation attach vmware-tools.iso to that vm from cloudstack and install it on browser itself.
I have the same problem as the poser of this question:
System.Data.OracleClient requires Oracle client software version 8.1.7
I have made the changes to the security settings on the oracle folder, and have to wait for the server to reboot overnight.
My question is why is this reboot necessary? I am getting the same error after making the changes without rebooting, so I don't doubt that it is. Is there an alternative to rebooting the server, like IISRESET? (Although I wouldn't be allowed to run IISRESET during the day either)
Perhaps not an answer to your specific question, but for the record it is for this kind of reasons that I always favor Oracle Instant Client :
You don't have to install anything on the target machines (including dev boxes !). So no tricky manual setup and goat sacrificing.
You can make sure that your application will run with the specific client you picked (version, x86/x64).
You could even easily have multiple applications work with different client versions on the same computer.
As a downside, it adds a significant weight to your application (~19Mb minimum), and you can't participate in distributed transactions.
If you still can switch, this is the way to go IMHO. Check What is the minimum client footprint required to connect C# to an Oracle database? for more information.
Starting with Server 2003 (hosting IIS6) it is enough to restart the service to bring environment changes and security changes into effect.
But this is done with iisreset. What is not allowed too.
Thats a pity, I see no other way as wait.
