Another bug in the OSCEXO module… When searching for mails within a mailbox well known folder with more than “PageSize” messages the cmdlet Search-OSCEXOEmailMessage never return and keeps “searching” forever (or until you run out of memory – whatever happens first). The reason behind this is that the code that handles the “ExchangeService.FindItems()” calls does not increase the PageOffset and […]
When trying to use the Clickatell SOAP WebService via “http://api.clickatell.com/soap/webservice.php?WSDL” you receive a “FileNotFoundException” exception: You effectively have to use the workaround described in the manual by calling the web service under this address: ‘http://api.clickatell.com/soap/webservice_vs.php?WSDL’. The reason behind it seems to be use of a conflicting attribute named ‘callback’.
When using the System.Net.WebClient class you are actually using a class that wraps WebRequesr and WebResponse with some benefits as abstracting stream and handling logic. However, this, comes at a price and sometimes along with some errors, too. When a web server responds with an HTTP 500 Status the WebClient throws an exception and you do not have access to […]
As already described on elsewhere on the Internet and on Microsoft Connect, the new Invoke-WebRequest Cmdlet, that comes with PowerShell v3, handles form fields incorrectly. Instead of referring to the name attributes of input elements within a form the Fields Collection stores the ids of the attributes under the ‘key’ property. As in the following example you see the text […]
[UPDATE 2014-04-08] Thanks to Meir I updated the post as the code was missing the definition for the regular expression. Now I corrected that, so the code should work now. In addition, I found out that the apple web server is not serving ‘Set-Cookie’ header according to RFC so I changed the example from apple.com to google.ch (as we are […]
Serialising and Deserialising data structures is pretty easy when using Export-CliXml/Import-CliXml. However, there are some gotchas. In addition to the already described bug when using [ordered] hashtable in PowerShell v3 with Import-CliXml there is another error when importing [Array] with Import-CliXml: an [Array] becomes an [ArrayList]. The following code shows the problem: Again, this error seems to occur when you do […]
When you have a DistributedVirtualPortGroup in vCenter (vC) with a fixed number of VirtualPorts of 10 and you set that DistributedVirtualPortGroup to “non-expanding” you will get an error with vCloud Director (vCD) when you try to allocate more than one (1) DistributedVirtualPort. However, when you look at the DVS DistributedVirtualPortGroup you find enough available DVS DistributedVirtualPort displayed. The error message […]
When you try to add a “Global Blueprint” in vCenter Automation Center (vCAC) 5.1 for an Organisation VCD (OvDC) in a vCloud Director (vCD) endpoint you cannot save your settings if you have no Organisation Networks (OrgNetwork) defined. As the selection of a network (and a storage path) is mandatory input and the selection list for the networks is empty you […]
Recently I quickly mentioned the universal PowerCLI applet Search-Cloud that can be used when dealing with vCloud Director. Howevery it seems you have to verify its output when using it to query Provider Vdc parameters. The output mixes the “allocation” and “used” counters for CPU, Memory and Storage as you can see in the example below (“used” is larger than […]
Today I want to share a funny experience we had with a clean vCO 5.1 install … Having a freshly installed vCenter 5.1 with an integrated installation of vCO upon first startup the vCO Service did not start and took (15!) minutes to finally reach a state where it was between starting and stopping. The log files included lots of […]
In vCloud API (via REST, vCO PlugIn, or PowerCLI) you can query CPU, memory and disk usage for VDCs. However, when retrieving the values for current CPU usage you always get ‘0’ – regardless of real current usage. Values for memory and storage seem correct. There is a workaround for this via querying the underlying vCenter resource pool for that […]
The new powershell feature “ordered” hashtable (a new PowerShell feature in v3. See OrderedDictionary Class) becomes an ordinary hashtable when it is imported via Import-CliXml. There is a “active” bug on Microsoft Connect OrderedDictionary becomes Hashtable when exported to and imported from clixml but no action for a couple of months. As a workaround do not use ordered hashtables but […]
