go to post Robert Cemper · Feb 19, 2019 structure is OK, and it worked for me.Removing all CR,LF,TAB,BLANK still looks good here. Could you have some control characters in your string ?USER>ZZDUMP myfile may show itUSER>write $TR(myfile,$c(13,10,9,32))<Oceano><Header><DataSource>Oceano</DataSource><DataType>EDAttendance</DataType></Header><Body><MIU><Department>BCH</Department><TotalNumber>6</TotalNumber><NumberWaitingToBeSeen/><LongestWaitMin/></MIU><MIU><Department>BOS</Department><TotalNumber>1</TotalNumber><NumberWaitingToBeSeen>1</NumberWaitingToBeSeen><LongestWaitMin>109293</LongestWaitMin></MIU></Body></Oceano>
go to post Robert Cemper · Feb 19, 2019 this happens if your variable myfile doesn't have a clean XML structure check the content it. eg: https://www.w3schools.com/xml/xml_validator.asp
go to post Robert Cemper · Feb 18, 2019 By XML bit I understand you have some myfile="<mynode>anytext</mynode>" or similar in handsso this should cover your needs:USER>set sc=##class(%XML.TextReader).ParseString(myfile,.reader)USER>zwrite @reader.GlobalName^||CacheTemp=1^||CacheTemp(1,1)=$lb("element","","mynode","mynode",0,1)^||CacheTemp(1,2)=$lb("chars","anytext","")^||CacheTemp(1,3)=$lb("endelement","","mynode","mynode")or is the content of myfile something else ??
go to post Robert Cemper · Feb 12, 2019 First, CACHETEMP doesn't maintain a Journal. (could be a minor advantage) .Second, CACHETEMP follows a different storage strategy as it is kept in memory (global buffers) as long as affordable.While for the other DBs data (global buffer blocks) get written to disk as soon as possible it is the opposite for CACHETEMP.Third, CACHETEMP is common to all namespaces.Forth, CACHETEMP is cleared at every restart and total empty after. I doubt that this could be useful in an ECP setup.
go to post Robert Cemper · Feb 12, 2019 to my understanding, there is no technical limit.Though I believe to remember that it used to be ~16.000 some time in past.Class SYS.Database maps to ^SYS("CONFIG","IRIS","Databases",<DBNAME>) and has NO limit theresimilar Namespaces are stored in SYS("CONFIG","IRIS","Namespaces",<NSPCE>) an are covered by %SYS.Namespace If there is any limit it must be related to internal memory structures. (gmheap ??)

go to post Robert Cemper · Feb 6, 2019 In addition to the reply from @Evgeny Shvarov :INT is highly important to identify error locations.eg. <DIVIDE>label+5^routinename refers to the location in routinename.INT
go to post Robert Cemper · Feb 5, 2019 Out of curiosity, I have built a more exotic solution that is easier to understand. (At least for me)I don't like so much this protocol upgrade stuff and encrypting and simulation of a browser.My personal workaround:start browser over ZF(-1, "start chrome http://.................my csp......")the page gets my request passed with the URL. very simple just as a Hashthe page does all the WS stuff via JavaScriptthe reply is returned using Hyperevent #call(....) It works fine and is rather "classic CSP" style.

go to post Robert Cemper · Feb 4, 2019 To me, this looks like your port doesn't like WS as initial connection protocol but expect the switch from HTTPS -> WSS or the port is just wrong.several suggestions for the investigation to get it moving:#1) verify your server from a normal web page (e.g. based websocketdem.csp in Samples) especially the port !!!!#2) If you have control over your server then skip SSL and get running over HTTP -> WS first. You can add this once it works.#3) If you have no server just use Caché / SAMPLES / Web.SocketTest.cls I found it very useful to have control over both ends and now I own several variants for testing.Staying tuned

go to post Robert Cemper · Feb 4, 2019 #1) if it is a Caché Backup you need an Installation of Caché to restore it.#2) if it is a CACHE.DAT file you also need an installation of Caché and mount this as an additional DataBase.Without the installation of Caché it's a thrilling exercise to high-level experts. Not really advisable.try to have the same processor type { big / little endian :== (Intel/AMD) or not } as the original Caché instances. This saves some headache.Forget about SQL Server. Caché is far more efficient and advanced technology!
go to post Robert Cemper · Feb 4, 2019 #1)You need to get %Net.HttpRequest in hands to set your property Content Type.#2)instead of PutURL(...) you have to use method SendFormDataURL(....) of EnsLib.HTTP.OutboundAdaptermore details in docs here:Creating Custom HTTP RequestsIf you use the more common methods of the HTTP outbound adapter (such as Get), the adapter automatically creates and sends an HTTP request, which can include either form data or a request body. In special cases, you may want to create a custom HTTP request so that you can specify details such as proxy authorization or a different character encoding.To send the custom request, use the SendFormDataArray() method of the HTTP outbound adapter as described in “Calling HTTP Commands” in the previous chapter. Then see the chapter “Sending HTTP Requests and Reading HTTP Responses” of Using Internet Utilities.

go to post Robert Cemper · Jan 26, 2019 I'd personally prefer that $LB(var) also follows the elementary rules of COS.Though I have no hope on any ProdLog on this subject
go to post Robert Cemper · Jan 26, 2019 as pointed out by Alexander Koblov already:you can create a $LB() od $LB(undefined) and it's all the same set a=$LB() zzdump a 0000: 01 or write $d(undefined) 0 set a=$lb(undefined) zzdump a 0000: 01 Your coincidence of NULL, null, Null, nuLL, .... is just an optical eye-catcher without syntactical relevance in COS
