我在 HA Exchange 环境中顺序调用多个 powershell 命令时遇到问题(在单个开发主机上一切正常)。只要它只是关于交换命令,我就通过管道传输多个命令(执行在同一个节点上)来使用解决方法,一切都很好。我的代码:
string casUri = "cas1.srv.net/Powershell?serializationLevel=Full";
string credentialUserName = "User";
string credentialUserPassword = "secret";
string newOU = "thenewou";
string baseOU = "OU=root,DC=srv,DC=net";
System.Security.SecureString passwd = new System.Security.SecureString();
foreach (char c in credentialUserPassword) {
passwd.AppendChar(c);
}
PSCredential credential = new PSCredential(credentialUserName, passwd);
WSManConnectionInfo connectionInfo = new WSManConnectionInfo(
new Uri(casUri),
"http://schemas.microsoft.com/powershell/Microsoft.Exchange",
credential);
connectionInfo.AuthenticationMechanism = AuthenticationMechanism.Default;
runspacePool = RunspaceFactory.CreateRunspacePool(1, 5, connectionInfo);
runspacePool.Open();
powershell = PowerShell.Create();
Command command;
command = new PSCommand();
command.AddCommand("New-ADOrganizationalUnit");
command.AddParameter("Path", baseOU);
command.AddParameter("Name", newOu);
command.AddParameter("DisplayName", "My new OU");
powershell.Commands = command;
powershell.Invoke();
// ... another AD commands: Set-ADForest, New-AcceptedDomain (work fine)
// v--- trouble
command = new PSCommand();
command.AddCommand("New-GlobalAddressList");
command.AddParameter("Name", "GAL.Name");
command.AddParameter("RecipientContainer", newOu + "," baseOU);
powershell.Commands = command;
powershell.Invoke();
单主机环境不存在问题。在这样的 HA 上,另一个命令在不同的主机上运行:
[myApp]---[CAS load balancer]---[CAS-1..CAS-N]---[EX-1..EX-N]
这会导致异常:
Active Directory operation failed on DC2.srv.net. This error is not retriable.
Additional information: The name reference is invalid.
This may be caused by replication latency between Active Directory domain controllers.
Active directory response: 000020B5: AtrErr: DSID-03152804, #1:
0: 000020B5: DSID-03152804, problem 1005 (CONSTRAINT_ATT_TYPE), data 0, Att 9b7f0292 (msExchSearchBase)
我不知道如何为几个命令强制使用单个远程 shell 的持久连接。你有什么解决办法吗?
