JCA / JDBC configured for non - XA trying XA Transaction Commit

I'm trying to create a simple composite SOA BPEL in SOA 11.1.1.5 who use a DbAdapter to run a stored procedure in an 11 g database. The database task are executed only involves a single database and doesn't require transaction support. I carefully strengthened with the creation of the data source and JCA pointing through the DbAdapter to the JDBC DataSource if support for XA transactions is disabled, the JCA pool sets the mode of transaction "without transaction" and the JCA pool uses the value of data source to point to the poolside JDBC JNDI name rather than the value of xADataSource.

Visually,.

Definition of data source:
name = jdbc/myserviceDataSource
Driver = oracle.jdbc.xa.client.OracleXADataSource
URL = jdbc:oracle:thin:@mydbhost.myfirm.com:1521:GENERIC
Use the unchecked = XA data source
set the time-out XA = unchecked
Keep XA connection until the transaction completes checkmark =
keep the connection once the local transaction = checked

JCA definition:
name = eis/DB/myserviceDataSource
dataSourceName = jdbc/myserviceDataSource
xADataSourceName = (empty)
class name of platform = org.eclipse.persistence.platform.database.Oracle10Platform
Transaction | Support for transactions: any transaction

This configuration works on a single server sandbox and I got it in a second sandbox server. However, after you delete the JDBC and JCA pools to go through the process once more to document the procedure on the second server, I am unable to get configuration working again. The WebLogic domain seems to be to resurrect portions of an old configuration that still refers the poolside JDBC JNDI name in the xADataSourceName parameter. I unzipped the archive DbAdapter.rar to the DbAdapter and verified that the content of the fichier./META-INF/weblogic-ra.xml do not use the xADataSouceName parameter. The deployment Plan for the DbAdapter (called DbAdapterPlan.xml in $SOA_HOME/soa/connectors) also explicitly configures the JCA pool using the dataSourceName leaving blank the value xADataSourceName.

However, the SOA service using the JCA connection generates this error:

java.sql.SQLException: cannot call Connection.commit in the distributed transaction.

Again, I know the theoretical answer to this question is to disable transactions in the JCA and JDBC configurations and do not use the xADataSourceName of the JCA configuration element to point to the JDBC pool. However, after the validation of these items and restart the pools or perform an update on deployment of DbAdapter, WebLogic always seems to create connections via the JDBC pool with transactions enabled.

Any suggestions?

Should I just completely the DbAdapter undeploy and redeploy from the SOA's binary installation directory? These are just machines laboratory right now so that is obviously not a response of good long-term for production, but can help to start over with a better procedure to do this refining.

You must use a driver for your data source non - xa...

Weblogic documentation...

Configure the Options of the Transaction
When you configure a data source JDBC using the Console of WebLogic Server Administration automatically selects the options of specific transaction according to the type of the JDBC driver:
For XA drivers, Protocol selects automatically the Commit in two-phase system for the treatment of the overall transaction.
For the non - XA drivers, local transactions are supported by definition and WebLogic Server offers the following options...

  • Thunderbird 38.3.0: No writable calendars are configured for the invitations with the provider for Google Calendar 1.0.4

    Hello

    I searched many hours today in the internet and your forums, but it seems that this problem is not solved yet:

    No writable calendars are configured for the invitations with the provider for Google Calendar.

    My Thunderbird is 38.3.0 and the provider for Google Calendar 1.0.4.

    I put calendar.google.enableEmailInvitations; true but it did not help. I also tried [email protected]... @googlemail.com. Calendar works fine, it syncs, I see all the entries etc. But I can't accept invitations even IF she must have write access.

    What can I do? Is there a solution for this?

    Thank you!
    Daniel

    Use CalDAV here to access Google Calendar via lightning. I have no experience with the add-on of the provider.
    In any case, it is my understanding that you must assign an e-mail address to a calendar in order to be able to accept the invitations for this calendar. I see that in your screenshot.
    You can try to remove the Google calendar in lightning and re-create it. Given that all the data is on the server nothing will get lost.
    Or you may want to try CalDAV.

  • Where can I find instructions for alternative configurations for my time capsule?

    I am resident in a House with a router not apple using Uverse.  I just bought a Time Capsule, hoping to use it as a storage drive to backup my imac and mac air.  For the MacAir, I would be like it is able with time Capsule wireless backup, and depending on how I can configure the system, connect the imac directly to the TimeCapsule or wireless connection.

    What I can't do connect the Capsule of time with an ethernet cable to the router not apple, that is in a different room than my desktop.  I have permission to use the internet service provided by the non-apple router - so right now, I don't have time Capsule to provide internet access in itself - as long as it can enable to backup wireless option at least for my mac air.

    Any suggestions?

    Unfortunately, you're stuck in the middle of a router that is not apple and an Apple router without ethernet... and therefore no way to connect.

    What you need is a wireless bridge (wireless to ethernet bridge if you want that it is more accurate).

    Wireless bridges are pretty cheap... Look at TP-Link, because a lot of their wireless access points will make wireless bridge...

    Or you can purchase an airport express... It's the only apple router which allows the wireless bridge. However, it is more than twice the price of an equivalent of non-apple.

    With the bridge... you plug in ethernet on the TC and run the TC in bridge (it is the router bridge)... your clients can then connect to the TC directly and the two backup and get internet at the same time... otherwise you can do it in the order...

    That is, you can plug the TC to the iMac by ethernet. It's a bit complicated, but I've given instructions here. Then you have wireless internet and backup on ethernet... It is indeed the best configuration for the imac.

    Time Capsule using wired for Mac for backup only.

    What you can't do, is use wireless for internet and backup at the same time... you will need to do one and then sometimes switch for the wireless of TC to run a backup... not a great idea.

  • How can I remove guest account configured for the administrator?

    I tried to add a second user account on my computer and I blew it. My main user account is now defined as a standard account and no matter how many times I click the button to set it as an administrator account that he will not save these settings. The guest account (which I want to delete) is defined as an administrator account and it wont let me save it as a standard account, because there is no other administrator accounts. Even when I try to create a new account just to see what he would do he tells me that he cannot accept some of the characters that I use for the name of the account, even if it's just 5 letters, so I can't even create the new account.

    I have no idea what's going on with my user settings, but I want to just that everything back to how it was before... with a single main account configured for the administrator.

    Can someone help me?

    I bet that your administrator account is an admin account and your guest account is a regular account. Buttons that you look at don't tell you the State of the special consideration, but the change that you can apply. In other words, looking at the administrator account, the 'Administrator' button is highlighted not because it's already an admin account!

    Now you should do this, in the following order:
    1. Create a CD to repair Windows via Control Panel / backup and restore. People like you who make their own PC maintenance need.
    2. Test the CD.
    3. Create, test, and document an admin account to spare, even you have a spare House key.
    4. Disable the guest account.
  • CPL configuration for the handling of source on VCS - E

    Hi all
    When we tried to have a video call with an external company on the VCS - E, the address IP of CUCM appear in the distant field rather end when making external calls.

    It occurs because the SIP URI field on the sx device interface has completed our IP CUCM ( [email protected]/ * /)

    We are discussing with the TAC engineer, this problem can be solved by making one of these options below
    • 1-) field of sets for the CUCM so the field will not appear the IP address.
    • 2-) save endpoint on the VCS.
    • 3-) script on CUCM to change the SIP header and standardization for more details you can check out the link below:
    • 4-) - write scripts CPL on the VCS.
    • According to above choice, the only way to solve this problem for us applies a CPL
    • as much as I did research it is also not possible to change the source with the CPL on VCS - E. is it good?

    anyone can share me a CPL configuration for this manipulation? What I would do is this show get [email protected] / * / instead of [email protected] / * / address.

    [email protected]/ * / > [email protected] / * /

    our topology is device SX > CUCM > VCS - C > VCS-E > Internet

    VCS version is X8.7.1

    I would send me a CPL config for it.

    Thanks in advance

    Halit

    Can you provide a copy of your rules of research of VCS and a search for the call history failed.

    Hi Mike, the built-in client for MAC does not work with the RV220W. The reason is, the MAC IPSec client is the same as the Cisco VPN 5.x client.

    The reason that this is important is that the 5.x client work that on certain small business products include the SRP500 and SA500 series.

    I would recommend that you search by using a client VPN as Greenbow or IPSecuritas.

  • who can help me with "insufficient resources to meet the level of failover configured for vSphere HA.

    Hello world

    We tried to gif a 14GB of ram and make server complete a booking for her.
    This is a server for the exams and the vendor told us to do.

    I can't any more then 5500MB reservation on it, when I anymore that I get
    "Insufficient resources to meet the level of failover configured for vSphere HA.

    We have:

    2 X 5.1 ESXi hosts
    Each host has
    2 x processors (8 Cores each) with HT active.
    255,75 GB of Ram

    vSphere HA has been activated.
    Admission control policy is enabled and that the ability to failover is 1 host.

    What is the problem here?

    Thank you
    Ernst.


    Admission control policy is all about to give you the kind of guarantee that if the host failure happens then there will be enough resources to perform the successful failover.

    in simple terms, it comes to reserve the resources of failover.

    I would recommend going through the notion of vSphere HA, reduced control policy the following document.

    https://pubs.VMware.com/vSphere-60/topic/com.VMware.ICbase/PDF/vSphere-ESXi-vCenter-Server-60-availability-Guide.PDF

    From the Page number 22, the details that you need to study is given. Focus especially on part calculations Slot size of it.

    in your case you HA vSphere with number of failure of host to tolerate as admission control strategy defined.

    This means system will calculate CPU and memory slots out of the resources in your cluster, and the total number of units, it will keep some resources like reserved for failover, and others will be available to be used. It all depends on how much failure of hosts that you want to tolerate.

    now in your case, if you try to increase booking one of the virtual machine, which will then affect the number of locations in your environment, and so reserved ability to failover is violated, the system will not let you do what you want to do. As the energy on a virtual machine, or growing booking a powered VM etc..

    If you find that you have enough resources in your cluster and due to some virtual machines with very large cpu or memory reservation, number of places is less than you can still manage the settings some advanced in vSphere HA configuration, but I strongly recommend, try to take the help of someone who has done it before.

    also try to go through other admission control strategies which are explained in the document for more inputs.

  • Invalid configuration for the device 3

    Hi all

    I have set up a lab nested with three hosts esxi and two warehouses of data connected with the Microsoft iscsi target server. I know nested vm is not supported, but I'm trying to implement this workshop because I support a real VMware environment and I wish I could test some things before I break anything, so it's important. I get this error when you try to create a virtual machine "invalid configuration for the device 3.  Someone knows how can I know where is the problem?

    Thank you

    I think I can find the answer, it seems that it could be a windows problem causing data corruption. Somehow I created a VM but get all kinds of error trying to create an another VM.  Iscsi targets set up using windows server 2012 and it seems that there is a fix from Microsoft below which deals with corruption LUNs in windows 2012.  I have not yet tested, but this seems to be the right direction. http://support.Microsoft.com/kb/2908783

  • Not enough resources to meet the level of failover configured for vSphere HA

    I have a cluster of vSphere based 5.0 based on ESXi 5 knots 2.

    When I try to start a virtual machine, I get an error saying that there is "insufficient resources to meet the level of failover configured for vSphere HA.

    If I turn off an another VM the problem disappears and I can turn on my VM.

    If I try to turn on the virtual machine, I have already turned off, I get the error again.

    It seems obvious that there is a lack resources or some setting is misconfigured, but even after reading the forums and manuals, I am unable to locate the critical resource or parameter that is not correct.

    Based on my experience or vSphere server and ESXi servers are overloaded.

    I have an another similar cluster of hosting a larger number of virtual machines with no similar problem.

    This performance counter and this setting should check to identify the bottleneck?

    Concerning

    Marius

    To check reservations for virtual machines, I would select the Cluster in your vCenter inventory, then select the resources"" tab.  Which displays the child objects of the bunch (VMs, Resource Pools, vApps).  There you can watch settings of CPU resources and memory.  You'll want to watch the column of "Reserves".

    To find the size of the slot and places available, look at the tab "Summary" of your cluster.  There is a tile marked "vSphere HA.  In this mosaic, there will be a link for "Advanced Runtime Info" which will open a new window with the location information.

    When the Admission AP policy is set to "Number of failures of host cluster will tolerate", HA has a very pessimistic view of your resources, since it must be able to handle all the possibilities.

    Another option would be to change the admission control strategy in settings of Cluster HA to "percentage of resources reserved for failover.  It reserves a part of the resources for use by HA in the case of a failover, rather than trying to calculate the size of the individual virtual machines.  With a 2 cluster nodes, I think it a relatively safe bet to set these values to 50%, as your worst case scenario HA would be losing a single host on 2.

  • Best configuration for Pegasus J4(up to 4 HDD/SSD's) - RAID or JBOD?

    I'm looking through a configuration of Pegasus J4 Thunderbolt disc for installation in first, until I can buy a more robust solution (probably Pegasus2). I am trying to determine what would be the ideal configuration for best performance on the casing of the drive. I apologize for my ignorance, but from the point of view of creation, that I'd better be using 4 small SSD (120-240 GB each), set up as JBOD? or should I use 7200 rpm disks, configure in RAID 0? Connection via Thunderbolt.

    Thanks in advance.

    See Page Tweakers - External Drives

    If you read carefully, you will notice that 2 SSD is max Thunderbolt connection, then add more SSD does not improve performance at all, will cost more.

    Four conventional disks 7200 RPM in raid0 will be released also (almost) max the Thunderbolt bus, but are much cheaper and offer much more space. JBOD is not desirable, because of lagging performance.

    4 x 1 TB HARD drive @ $70 = $280 less than 2 x 256 GB Samsung SSD Pro 840 @ $220 = $440

  • Optimal configuration for vSwitches?

    I used to have a configuration with a bunch of different switches and each switch had his own Teddy bear, etc.  Virtually every assignment (iscsi, VM, vmotion, SC) has their own assigned Teddy.

    "After reading a Dell ' good practices ' (http://www.dell.com/downloads/global/products/pedge/en/poweredge-configurations-for-virtualisation.pdf) PDF file, I thought their way makes much more sense how I had mine Setup.  So here's how I think to do so (following quite close to their examples):

    vSwitch0 (3 natachasery plugged into a Cisco 6509 in etherchannel):

    Traffic - VM

    -SC

    -VMotion VMKernel (VLANs separated)

    vSwitch1 (2 natachasery plugged into a Cisco 6509 in etherchanel):

    iSCSI - SC

    -iSCSI VMKernel

    Does make sense?  Also, how do I know what vSwitch is used for iSCSI traffic because I don't see an option to turn on iSCSI as it is marketing VMotion?

    Thank you.

    Because the service console is used that for the discovery of the volume, not the traffic connection, it won't really matter.  I'm not sure to be used and am a little surprised that you were able to create 2 ports of console service on the same subnet.  I remember running into an error when I tried.  Maybe I'm remembering something similar though.

    I don't know how to determine which service console port to be used.  Maybe on the side SAN?  Maybe you can tell what IP made the discovery.  It can use one or the other at different times though. You should see that the IP address of the VMKernel connected to the volume however.  Who assure you real iSCSI traffic is on the good vSwitch.

  • Best Configuration for optimal IO RAID parameters and ESX 3.5 vmfs volumes

    Hello

    We currently have ESX 3.5 update 3 installed on a HP DL585 and connected to a HP MSA 1500.  ESX is installed on the server in a RAID 1 2 x 72 GB configuration.  I tried to determine the best possible configuration for the VMFS partition on the MSA 1500 (or more), but it seems to be getting some mixed reviews between RAID 1, RAID 5, and RAID 10.  That's why I thought I post the question and I hope that some people have recommendations.  Even if the disk size and type may be the best available and we can add to write the memory cache to the MSA then let me know the following... I'm coming looking with better i/o performance overall as well as redundancy (number of readers and size is not limits so if we had better available so how would he).  Assuming that VM will perform a high volume of reads/writes:

    1 size Max of LUN to optimize i/o performance (I have read 250 GB but perhaps it can be more)?

    2 for the LUN RAID configuration (RAID 5 or RAID 10, as well as all others who may still be better)?

    3. number of disks to span as appropriate?

    4. the amount of memory to install in the table itself or if anything be installed within the guest card and/or fiber ESX?

    Thanks in advance

    I'd say go with RAID 10

    Number of disks and the size depends on the VMs that spins the discs,
