Is View Journal of Cache Management Portal the only way to search in Cache journals? I need a way to define several search conditions and Portal often breaks on http timeout.

Every time I click Save on  System > Configuration > Memory and Startup page, I get "ERROR #5005: Cannot open file '/var/cache/cache.cpf_XXX' " error message, where XXX is a random number. This problem appeared some time ago without any clear reason. All file access right are seems OK.

Any ideas?

(We are in contact with IS support for this problem but I would like to ask Community too, perhaps somebody experienced this problem in the past)

Hello Community,

we need your help with Cache 2017.2 freezing on Linux machine.

Since we moved our primary production Cache from Windows to Linux in the begging of this year, we have experienced system freezing twice. Yesterday without any good reason Cache stopped to respond with the log shown below.

Questions:

• Any idea what could cause WRTDMN freezing?
• What actions it makes sense to take in order to have enough info when the system freezes next time.

Hi Community! I need your advice.

The method below is 6 times slower on production server than on developing machine:

ClassMethod runme4()
{
    s cnt=615210
    s st=$zh
    for i=1:1:cnt {
        s p=##class(digi.packet).%OpenId("packet||5237")
        w:p="" "not found",!
        k p
    }
    w $zh-st,!
}

BUT the server is 6 times faster if OpenId replaced with simple read of a large global (s p=^someLargeGlobal). Any ideas what makes OpenId so slow only on the server?

If two globals have same structure, how to reuse one CacheSQLStorage-based class to read both locations?

Thanks!

Update:

Let's say we have two globals:

^a(1)="dataa1"
^a(2)="dataa2"

and

^b(1)="datab1"
^b(2)="datab2"

i.e. the structure difference is global name only.

I would like to have two classes TableA and TableB both are inherited from TableAB, and TableAB taking global name as a parameter.

A simple question: View Global Data  page shows globals always in ascending subscript order. Very often I need to see latest page, is there any trick for this?

Update: I mean to see last subscripts in Management Portal, not using the code

A quick question regarding to SQL Query Plan:
Why these two requests have different plans, in particularly, why second request needs temp file? To me, temp file is a bad thing which should be avoided, right?

1. select * from Test.Log where cdate = 1
2. select * from Test.Log where cdate > 1

Plan for 1:

Read index map Test.Log.cdateIndex, using the given %SQLUPPER(cdate), and looping on ID.
For each row:
 Read master map Test.Log.IDKEY, using the given idkey value.
 Output the row.

Plan for 2:

Call module B, which populates bitmap temp-file A.
Read bitmap temp-file A, looping on ID.

For each row:

All of the sudden, Cache Studio's Debug->Run command started to fail with error '6704 Target has exited debugger' (German: Kein Anbinden möglich). What could be a reason of that? Today we installed Cache Web Terminal (https://intersystems-community.github.io/webterminal/
), could it be possible that the terminal somehow hijacked some debugging api end-point?

Update: any idea what error 6704 means exactly? Studio was able to launch debugging job but it unexpectedly exited? German text seems is trying to say "Can't connect"

I have global with binary data, structured like:

^a(1)=<binary>

^a(2)=<binary>

^a(n)=<binary>

What could be easiest way to read it via Stream interface? I.e. to pass an adapter to a function expecting Stream?

I'm getting this compilation error:

Kompilieren der Klasse digi.packet
FEHLER #5002: Caché-Fehler: <FUNCTION>zLockUse+5^%ExtentMgr.GlobalRegistry.1
  > FEHLER #5030: Während der Kompilierung von Klasse 'digi.packet' ist ein Fehler aufgetreten

when importing one of my classes on the production server into one particular namespace:

Time after time on CSP Session page of our Cache 2017.2.1 installation I see that all licenses are consumed by CSP sessions of /csp/sys, /csp/sys/op/and /csp/sys/mgr applications which I assume are sessions of Management Portal. The problem is that there are only few of us accessing the Portal and as we test by browsing Portal, we can't reproduce the problem. 

Is there any way to see client IP of CSP session? Any other way to approach the problem?

The problem looks very similar to the Forefox-related one but we don't use Forefox.

%XML.Reader.OpenFile fails with SAX XML Parser-Error: <STORE> on importing large (1.5 GB) xml file. Any workaround for it?

My goal is one-time import of the file using classes generated by its XML schema.

A function iterates global ^data(a,b,c) with $order using 3 nested for-loops. At certain point, for example with a=10, b=20, c=30, the function exits and later has to resume the iteration from the same point. What could be easiest way for it? My solution looks too ugly.

Has anyone managed to port ASP.NET Identity Caché Provider  to ASP.NET Core?

Edit: this one https://github.com/intersystems-ru/identity_cache I mean

Today %SYS.Namespace.ListAll started to report one namespace, for example USER, two times: once as "USER" and once as USER's database "^^c:\databases\user".

Details: my Cache instance has  50+ local namespaces. Today I have "touched" 3 of them (imported new classes), and now ListAll reports each of these 3 twice. Looks like ListAll is the only one who sees those strange duplicates, in all other places (Portal, Studio) only USER is shown.

Can someone explain what is happening?

Is it possible to export PRJ file without section BreakPoints and Target attribute? /diffexport does't help.

They just make noise when pushing into GIT

In case of system exception (missing property, method etc) Cache Studio's debugger stops at the line throwing it. Unless the line is in try/catch block. 

Is there a way to make it break also in try/catch case?

Cache 2016.1.1

Cache Studio almost always crashes when I click rows in Call Stack view during debugging. Then Cache has to be restarted because last edited file remains locked.

Looks like I'm the only one who uses the debugger. Or is there a magic spell to make stack view working?

Cache 2016.1.1

I have classes A and B, B derived from A, A has method Abc.

From INT of class B I see that compiler copies implementation of Abc to class B, so that Abc exists both in A and B.

As result, when B invokes Abs, B.Abs() is executed instead of A.Abs(). In result debuger is not able to step into Abs and breakpoints in A.Abs never hit.

Why this happens and how can I avoid this?

Update:

OK, now I know the reason: compiler makes the copy if Abc has this line:

s cn=##Expression($$$quote(%classname))
