sql - Oracle's imp.exe problems over tunneled connection -

-

we have oracle server running in remote server has ssh connection , need run data import process against that.

i tried different ssh tunnel combinations:

  • 127.0.0.1:1521
  • 127.0.0.1:1522
  • 127.0.0.1:11111
  • 127.0.0.107:1522
  • 127.0.0.107:11111

but none of them work imp.exe. intresting thing combinations works fine sql developer , scriptella scripts use jdbc. following error shown in standard error output:

imp-00058: oracle error 12514 encountered ora-12514: tns:listener not know of service requested in connect descriptor imp-00000: import terminated unsuccessfully

and following appears in sqlnet.log:

*********************************************************************** fatal ni connect error 12514, connecting to:  (description=(connect_data=(service_name=tktdb1)(cid=(program=c:\oraclexe\app\oracle\product\10.2.0\server\bin\imp.exe)(host=...)(user=...)))(address=(protocol=tcp)(host=127.0.0.1)(port=11111)))    version information:     tns 32-bit windows: version 10.2.0.1.0 - production     windows nt tcp/ip nt protocol adapter 32-bit windows: version 10.2.0.1.0 - production   time: 07-mar-2011 10:53:26   tracing not turned on.   tns error struct:     ns main err code: 12564     tns-12564: tns:connection refused     ns secondary err code: 0     nt main err code: 0     nt secondary err code: 0     nt os err code: 0

any ideas?

i asume connect strings correct. if are: database happen in restricted mode? in case, service supports not available connections. if case, try connecting tns alias using sid=xxx

i fail see ssh has impact here. database connection working. ssh plays role if need tunnel database connection through ssh. if normal sql client can connect without this, imp can same. ssh used connect server, not needed in case.

i hope helps, ronald.

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

razor - Is this a bug in WebMatrix PageData? -

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...

i need sort through array , sort each individual row in array in ascending order. doesn't seem going (surprise!) keep getting hit 2 errors: a2101: cannot add 2 relocatable labels , a2026: constant expected here's sort, makes sense me, think i'm still trying implement high-lvl language techniqes assembly. there way around not being able use relative values?
