database - TFS 2017 Error: TF401054 -


i've following issue: i've set new tfs2017 new databases. remapped tfs2017 our old tfs2015 databases described here.

when try connect tfs2017 in webbrowser following error:

tf401054: requested service level property tfs_service_level did not match expected value. team foundation server requires dev15.m105.5 service level database implements dev14.m102.

is there way manualy upgrade tfs2015 databases match tfs2017? or there way can fix this? (tfs2017 repair didn't help)

thanks in advance :)

edit:

i solved problem described here on msdn.

first off, article linked tfs 2008. in general, don't expect instructions applied version released in 2008 going same (or remotely similar) instructions version released decade later.

tfs 2008 didn't have same database structure tfs 2010 onward. don't know how followed instructions tfs 2015, since they're totally incorrect , reference command line utilities haven't existed 7 years.

i hope have backups of databases in known state; best bet going to bring working tfs 2015 instance , follow modern upgrade documentation.

the basic problem team project collection databases have upgraded. pointing tfs 2017 tfs 2015 project collection databases without putting databases through normal process of attaching them (and upgrading them) isn't going work. in migration-based scenario, typically accomplished via tfs admin console.

you may able go admin console , attach databases, recommendation bring working instance of tfs 2015 environment , start scratch.

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
