Re: [basex-talk] [bxerr:BXDB0002] Too many open files

[Mansi Sheth]

Thanks Joe for your input. I haven't tried all the options yet, but will
surely go thru.

I guess, what I was trying to see is, if there is a way I can optimize my
XQUERIES, to close open databases which it not longer needs. Currently, my
queries are something of below nature. I am thinking, if there is a better
way to deal with *bold* piece of code below.

declare variable $n as xs:string external;
declare option output:item-separator "";


let $queryData :=
for $db in db:list()

*let $query := "declare variable $db external; " || "db:open($db)" ||
$n*
*return xquery:eval($query,map { 'db': $db, 'query': $n })*

return distinct-values($queryData)

Re: [basex-talk] [bxerr:BXDB0002] Too many open files

[Mansi]

So, increasing ulimit, based on below blog helped.

Thanks,

Hi Mansi,

The results of ulimit can be misleading.  See this article - which really
helped me when I encountered this issue (though not with BaseX):

Re: [basex-talk] [bxerr:BXDB0002] Too many open files

[Mansi Sheth]

Thanks Christian,

I had already set open files limit on the OS:

ubuntu@ip-10-0-0-83:~$ ulimit -Hn



However, I still face exact same problem. Process breaks at the same db
count

[bxerr:BXDB0002] Resource "/veracode/msheth/BaseXDB/bi_output_715/inf.basex
(Too many open files)" not found.
