The operation could not be performed because OLE DB provider "SQLNCLI11" for linked server was unable to begin a distributed transaction -


i'm trying run distributed transaction machine (sql server 2012) client server (sql server 2008).

i'm trying run:

begin distributed transaction select * [172.01.01.01].master.dbo.sysprocesses commit transaction

and get:

ole db provider "sqlncli11" linked server "172.01.01.01" returned message "no transaction active.". msg 7391, level 16, state 2, line 2 operation not performed because ole db provider "sqlncli11" linked server "172.01.01.01" unable begin distributed transaction.

i can run select server data coming back, @ least know servers can see each other, , linked server exists , operating

now, there multiple posts on web this, can't work. have tried far: 1. set dtc properties following (on both server) enter image description here

  1. restarted distributed transaction coordinator (msdtc) control panel -> services (on both servers).

  2. uninstalled , installed dtc (on both servers).

  3. restarted remote server.

  4. turned off firewall on both servers.

  5. enabled sp_configure 'ad hoc distributed queries', 1 (on both servers).

  6. i ran dtcping , pinged successful.

  7. linked server properties changed following: enter image description here

what else there try?

update: running transaction server 172.01.01.01 works. therefore issue not on destination server, on machine source.

if after configuring ms distributed transaction coordinator (msdtc) on 2 sql server's according op's original post, still "no transaction active", should check each host reachable via ip (assuming that's you've used) registered in linked server.

for example; on recent setup, 2 sql servers reachable through network in 192.168.200.x range (same subnet), each server indirectly connected through ip in 10.x.x.x range. on 1 sql server, dns server used kept resolving target sql server it's 10.x.x.x ip (which firewalled) though linked server entry used ip in 192.168.200.x of target server.

it appears msdtc uses hostname of server, while sql server connects on linked connection using ip or hostname defined in linked server entry, leading confusing behaviour of apparent connectivity when checking target linked server within sql management studio, inability execute remote procedures on target.

the solution add entries in host file's (%windir%\system32\drivers\etc\hosts) explicitly force each sql server resolve other ip address on 192.168.200.x network.

on host 1 (ip 192.168.200.15):

# target server 192.168.200.20    targetserverhostname.and.any.domain.suffix  targetserverhostname

on host 2 (ip 192.168.200.20) 

# source server 192.168.200.15    sourceserverhostname.and.any.domain.suffix sourceserverhostname

don't forget ensure msdtc has been configured according op's screenshot above allowing network access , (if required) no authentication.

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod

thorough guide for profiling racket code -

did googling ("racket profiling", "racket measure performance"), didn't find , there no examples in docs. did google "profile" search on htdp - no luck. (profile (f ...)) output isn't obvious other small snippets. ideally want python's python -m cprofile usage examples. when search "python profiling", both duckduckgo , google give top result: 26.4. python profilers . (although scanned quickly, seems more of reference "thorough usage guide" examples. if had else in mind, perhaps please link that?) the equivalent racket documentation be: profile: statistical profiler . a usage example: #lang racket (require profile) (profile-thunk (thunk (function-to-profile arg0 arg1) )) here (thunk e) convenience (lambda () e) . bigger example: #lang racket (module mod racket (provide f) (define (f) (for/list ([i 10000]) i))) (require (prefix-in mod: 'mod)) (define (f) (for ([i 10000
