java - XA transaction for two phase commit -


Hi,

If two resources are included in a transaction then the XA Transition setting should be weblogic The server should be enabled then the XA drivers should be turned down. This is an alternative way of transacting two resources without enabling the XA transaction

< P> Yes, you can use global transaction emulation. Weblogic has two modes:
  • Logging Previous Resources - Weblogic creates a table in all your data sources and writes transaction data in this table. This is a preference option.

    From the official document:

    With this option, connection is used in transaction branch & gt; Transaction is processed as the final resource and in the form of a local transaction. & Gt; Record for two-step commit (2 pc) transactions is put into a table on record resources, and & gt; The result determines the success or failure of the prepared phase of the global transaction. & Gt; This option offers some performance benefits and two-step ambulatory & gt; Provides more data protection than commits, but there are some limitations in it.

    See

    • simulation two-step command - Transaction branch always returns "success" while preparing the steps. Select this option if your app can tolerate predictable conditions.

      See for more information.

      I like the LLR option, but if you work with legacy DB and you do not have a table grant, you should use two-step committed emulation.

c - Mpirun hangs when mpi send and recieve is put in a loop -

I was trying to use the program to use mifrewan on 4 node clusters. Distributing node 0 data in nodes 1, 2 and 3. In the program, from '90 'to variable values ​​of' dior 'to be calculated. Therefore the node is distributing data and collecting results in an omitted fashion (for different values ​​of var 'dir') when do {*******} Whereas (dir Loop is given, Mippun is hanging, and no output is found. But when I comment on two {*******} (dir The loop output is obtained for the initial value of variable dir dir = -90 ), and that output is correct. The problem occurs when the loop is given. Can anyone help me in solving this problem. #include "mpi.h" int main (int argc, char * argv []) Float dir = -90; Int rank, nanoprakash; MPI_Status status; MPI_Init (& amp; argc, & argv); MPI_Comm_rank (MPI_COMM_WORLD, & amp; Rank); MPI_Comm_size (MPI_COMM_WORLD, & amp; numprocs); If (rank == 0) {/ / data to begin / / (dest = 1; dest ...

python - Apply coupon to a customer's subscription based on non-stripe related actions on the site -

I can not find anything in the source about using coupons after subscribing to a user's plan. Is it possible to use a coupon to credit a user's membership after initial subscription? If not, what is the best option? Specifically, I want to give a user 100% coupon for that month, when they take 5 [site specific actions]. This is possible, but may not be the best idea. Coupons are currently applied to the stripe, then apply again at the customer level and each client can have a single coupon. So if you are already offering discounts to the coupon, then the customer who is currently in the present will also give up. It also means that if you are using a recently-added multiple subscription capacity, then all of the user's subscription will be ready for the month. Coupons can be set to "Once", only once (as the only name) can be used by any customer, so if this credit can earn more than once, You will have to maintain a 100% discount coupon continuousl...
