IP Pool

Hi,
Just want to create a class that provides a unique IP address to the client from the pool of available IP address. the client will then maintain possession of this IP address until a time when the workstation is ready to return the IP address to the server pool. on return, the IP should be made available for distribution to satisfy further requests. Any idea how to implement the mechanism for providing the pool? Its a bit stupid to use an array of IP addresses :).Any other more efficient way to do it?
Thank you very much for your help

RFC_FAILURE affects Connection Pool

Using VB.NET (2003) with .Net Connector 2.0.
An intermittent problem causes a RFC Call to fail, and an exception is raised in the .NET code. The Exception message is:
 See RFC trace file or SAP system log for more details
The Trace file shows:

This error adversely affects the Connection Pool as calls to other RFCs are now prone to similar intermittent errors
Is there any way to prevent the problem causing problems with Connection Pool ?
Is there any way of removing a faulty connection from the pool ? (NB Close and Dispose on the connection does not help)

The application is a Windows service - so I don't want to lose any connections. I assume that closing the connection (and not returning it) will affect the number of available connections in the pool(?).
I'm using async. RFC call, and the problem is detected in the callback function when the EndRFCCall is performed.
Original code:
Public Sub Execute_RFC(ByVal parameters as string())
' Assign SAP Connection to RFC Proxy
sapRFCProxy.Connection = SAPConnectionPool.GetConnectionFromPool(ConnectString)
Call the SAP RFC - Asynchronously
arAsyncResult = m_sapRFCProxy.BeginRFCCall( params..., AddressOf RFC_CallBack, objAsyncState)
End Sub
Private Sub RFC_CallBack(ByVal ar As IAsyncResult)
Try
 ' Retrieve the SAP RFC Response...
 Call sapRFCProxy.EndRFCCall(ar, param1, param2, etc...)
Catch ex As Exception
 ' Log the Error...
End Try
' Return the Connection
Call SAPConnections.ReturnConnection(sapRFCProxy.Connection)
End Sub
I have changed the code as suggest so that the connection is closed, disposed but not returned. This cleared the RFC_INVALID_HANDLE errors, but the main problem of a corrupted connection persists.
Diagnostics produced by the amended code:

How to delete the row in table control with respect to one field in module pool programming?

Hi,
Can I know the way to delete the row in table control with respect to one field in module pool programming
Regards
Darshan MS

HI,
I want to delete the row after the display of table control. I have created push button as delete row. If I click on this push button, the selected row should get deleted.
I have written this code,
module USER_COMMAND_9000 input.
DATA OK_CODE TYPE SY-UCOMM.
OK_CODE = SY-UCOMM.
CASE OK_CODE.
     WHEN 'DELETE'.
        LOOP AT lt_source INTO ls_source WHERE mark = 'X'.
            APPEND LS_SOURCE TO LT_RESTORE.
            DELETE TABLE LT_SOURCE FROM LS_SOURCE.
            SOURCE-LINES = SOURCE-LINES - 1.
        ENDLOOP.
But I'm unable to delete the selected rows, It is getting deleted the last rows eventhough I select the other row.
So I thought of doing with respect to the field.

Is there a limit of how many resources can be shared via a single Resource Pool in Project 2010 Professional standalone?

We have a single master project resource pool of over 150 resources that are shared across let's say 10-15 sub projects or sharer files.
We are using Microsoft Project Professional (standalone no project server)
Are you aware of any limitations outside of project server with resource pool and sharing, or should we be using Project server (as I have read a lot of articles about resource pool sharing working better in project server)
I'd like to get clarification on:
1. I read that the calendars for resources (of which there could be many shift patterns etc.) should always be created in the master project only, not in the sharer files. In my testing I see that a shared resource also brings the additional calendars from
the Master Project file - and can be chosen in the calendar column from Resource sheet.
2. Each sharer file can have it's own specific project calendar, but the resource calendar (used by the assigned resources from the pool) will drive the scheduling (as per normal), unless;
3. A specific task has a 'Task Calendar' applied to it AND "scheduling ignores resource calendars" is ticked.
I am trying to find an article that addresses, in detail, the limitations or 'look out fors' in this area. I have found plenty about how to create and share resources, but this is more troubleshooting.
Any advice or direction that can be given would be appreciated. Thanks.

No limit to resources, but linked master and resource pools are at high risk of file corruption if you rename, over-write or move a linked file without removing it from the master and pool first. Files will corrupt, its when not if.
Master files should never have any resources or tasks in them, only inserted projects.
I much prefer creating master files with the Link option deselected. This copies all data and consolidates resource info (so no pool needed). I record a macro to create new masters each week. This method has no corruption risk.
Your alternative now is to experiment with Project Server. By far the best way to prototype a system is to get Project Online through Microsoft, ProjectHosts or Bemo. It will give you access to a vanilla project server very quickly and cost for a few months
testing is trivial for a few users.
If you go ahead with a full implementation I strongly recommend getting a qualified Project Server partner to help you implement the full system.

How can I cancel the "Recreate All Virtual Dekstops" for a pooled collection in 2012 R2?

I currently have a system single-server installation of VDI, using 2012 R2 Standard as the server, using pooled collections of Windows 8.1. In general, everything works very well, but I've been searching in vain for ONE command. When
I make a change to the master template in Hyper-V, Checkpoint it, then go into the Remote Desktop Services, go the appropriate collection and initiate a "Recreate All Virtual Desktops", how would I cancel that?
It's happened on more than one occasion, where I make a change or an update to the template, and then push out the 25 new Virtual Desktops, and then the client comes back asking for a "little" change....but I'm stuck pushing it out until
all 25 desktops have been recreated. There must be a way to interrupt this process (probably leaving a few VM Desktops in an unstable state...which I don't care too much about as it's a pooled collection), update the template, and push it out again with
the "Recreate All Virtual Desktops". I do have the concurrency set so it recreates 5 at a time, but that noticeably impacts the users, and I don't want to just push out all 25 at a pop and interrupt everyone's work. Any ideas?

Hi,
Have you tried Stop-RDVirtualDesktopCollectionJob ? Something like below:
Import-Module RemoteDesktop
Stop-RDVirtualDesktopCollectionJob -CollectionName "PooledCollectionName" -ConnectionBroker "broker.yourdomain.com"

Front End servers within same Pool on different subnets

The customer is looking to have Amazon AWS host Lync 2013, and despite Lync 2013 having built in HA via Pools, Amazon wants to split the Pools across two of their availability zones (AZ ). An AZ is nothing more than a metropolitan area network, or simply
a data center located a few miles away. Essentially they want to split the Pools between their two AZs.
I know that for Lync 2013, the only stretch Pool supported is the Persistent Chat server Pool, and that Front End Pools, Edge Pools, or Mediation Pools are not supported.
Amazon states that the latency between their AZs is from 1 - 5 ms, which is well within tolerance, though they state that the AZs all have unique subnets.
I know that none of this is supported, though I am being requested as to why it isn't.
Forgetting about latency, is this not supported because all servers within a Pool must share the same IP subnet? Is this coded within Lync that only Pools within the same subnet will work? I think it is as with Lync 2010, a stretched VLAN was required for
a FE Pool to work, which implies the same subnet.
While on this, a Central site does not mirror that of an AD Site, where a Central Site is a reflection of Pools within an area. So can a Central Site span two AD sites? I believe the answer is yes when one considers that a remote branch office can also be
its own AD site. The reason for asking this question is I am attempting to see if if the Central Site might also have something to do as to why stretched Pools aren't supported.
Thanks!
Christian
Christian Frank

Hi Guys,
Just saw both of your responses. I totally agree that it isn't supported, and what Amazon has been proposing is essentially adding their HA via a redundant AZ so that their infrastructure is redundant, which is their HA (I don't agree!).
What I am looking for is something a bit deeper as to why. For example, when Lync 2010 had the stretched FE Pool between two locations, it was done via a stretched VLAN, which implies that the servers on both ends must be on the same subnet.
Amazon wants to stretch all the Pools, between their data centers, so they can say that the Lync infrastructure is highly available, though at each data center, the subnets will be different, and that is what I am attempting to validate.
I know this isn't supported, though is it because the members within the pool would come from different IP subnets, and Lync 2013 is coded to expect fellow members to be within the same subnet? That essentialy is what the case of Lync 2010 FE Pools was when
they stretched them. And if you go back to Exchange 2007, stretched VLAN was back then a way to create geo-clustering also, which is no longer the way.
Frankly, I think it has to do with subnet, and I believe it has to do with how the Windows Fabric is written, and what it is expecting to see. I really think this is the case, which explains the whys as to how stretched Pools are no longer supported any
longer. Yes?
Thanks!

ISE 1.2 IETF Attribute 88 Framed-Pool not available

Using ISE 1.2 and setting up a new Radius Server Sequence, I am unable to use IETF Radius attribute 88 (Framed-Pool) as it is not displayed in the Radius IETF Dictionary.
Is there a reason for this? Most other IETF attributes are available, I am curious as to why this one is missing
Thanks

Can not delete server from pool

Ok.....I think I'm on a sinking ship.....
I want to start from scratch.....deleting the SAN servers, server pool, everything and start over.....
however, I can not remove any servers from the pool because the manager thinks their in an error state. I rebooted on of the servers and it came up just fine. The manager is just messed up!
So how can I remove the server in an error state?
Is there a way to bring the manager back to where I started discovering the servers? Please don't say re-install or I will have to start looking for a rope.

I have barley got the system off the ground and am now facing a "re-install". With the problems that I am having and others I see on this forum....makes it look like this is still a beta product.
A system in production should not have to be "re-installed" to solve a problem....or that someone needs to do something at the OS level to do a fix. The manager should have the ability to "go back to factory defaults", do backups and restores of its data (not relying on backups/restores of the Oracle database).
I have a great 'rock sturdy" reliable system right now.....but is dated and I need to upgrade hardware. I need something as reliable to replace it.....
I guess I am just frusterated that their are some major bugs down deep that need to be addressed.

RFC Destination Connection Pool requirement

Hi Experts,
I have a custom webdynpro java application to display number of work items pertaining to that particular user in a backend.
There are users who dont use this functionality as well. But the requirement is to place this application in home screen.
I have used both metadata and modeldata with hard coded user since we did not want error messages to appear for users who do not have backend access.
Application & Access Details
Application Location : Home Screen
Concurrent Users : 600 concurrent users maximum possible value
Connection Usage : Close connection immediately using disconnectIfAlive() method.
Now I need to configure JCO Pool Size , Max Connections, Wait Time for the RFC destination.
I have read a lot of post and documents but could not acheive clarity of thought on this.
Kindly let me know what values I should give in these fields for optimal performance and no connection issue for users.
Regards,
Porselvan

Hi Muthavudaiyan,
Hope you are doing good.
Basically from the JCo perspective, there are only 5 parameters that are involved here:
jco.destination.pool_capacity:
Maximum number of connections that are held open in the pool for reuse (default: 1)
jco.destination.peak_limit:
Maximum number of connections that can be obtained from a pool at peak usage times
jco.destination.max_get_client_time:
Maximum time to wait for a free connection if the peak limit is reached before exception is thrown
jco.destination.expiration_time:
Timeout period after which pooled idle connections can be closed (default: 600000ms = 10mins)
jco.destination.expiration_check_period:
Regular time interval for checking if pooled connections have expired and will be closed
The values are determined by the application in question. The ideal values have to told to you by the application developer; there are no two ways about this.
Thank you and have a nice day :).
Kind Regards,
Hemanth

Connection pool / db failure

WLS6.0 sp2 / Win2k
Oracle 8.1.7 / Solaris 8
problem is if DB fails, the connection pool fails, and will not restart. If I run a java weblogic.Admin EXISTS_POOL command, it says the pool doesnt exist.
If i run a RESET_POOL, using the system user password, it comes back with:
Exception in thread "main" javax.naming.AuthenticationException. Root exception is java.lang.Securi
tyException: Authentication for user guest denied in realm weblogic
<<no stack trace available>>
I have test on reserved set (and dual as the table).
Anyone shed any light on what could be going wrong, because right now, every time the DB fails, we have to restart the **&$"&^ server.... (and that takes around 20mins for all the apps to init)

Hi Will,
When you bring up the server, if the database is down, your connection pools
will not come up if you have an initial capacity greater than 0. This is a
known issue and the workaround for this is to set the initial capacity to
zero so the pool comes up even when the database is down, then make sure you
set the capacity increment to the value that you like your initial capacity
to be and have the TestConnectionOnReserve to true.

Connection Pool Failure: "No suitable driver"

Hi,
Upon server startup, I get the following result:
<Nov 7, 2001 4:18:32 PM CST> <Error> <JDBC> <Cannot startup connection pool "ora
cleTrufflePool" No suitable driver>
I assumed it was a path problem, but in the startWebLogic.cmd script I've set the PATH and CLASSPATH variables to the same as in a separate command window that can successfully dbping the Oracle db.
One thing I completely don't understand is what the URL value should be for the pool, and I can't see a pattern in the examples and docs I've found on this. Here are my pool settings, at any rate:
Name: oracleTrufflePool
URL: myOracleServerName
Driver Classname: weblogic.jdbc.oci.Driver
Properties:
user=user
password=password
server=myOracleServerName
ACLName: user
Password: password
As you can see, I also don't understand whether the Oracle user name and password must be duplicated in the Properties section, or should they really only be listed in the ACLName and Password fields (in the Server Console UI)?
TIA,
Steve

Hi. The issue is that the URL you give is not the URL the driver (weblogic.jdbc.oci.Driver)
wants. The URL should be "jdbc:webLogic:oci". The properties user, password and server
will be passed to the driver for conenction attempts. The ACL is for who gets to use the
pool, and the other password entry is only if you need the DBMS password to be encrypted
in the XML. If so, set that password value, and don't have it in the driver properties.

I assumed it was a path problem, but in the startWebLogic.cmd script I've set the PATH and CLASSPATH variables to the same as in a separate command window that can successfully dbping the Oracle db.
One thing I completely don't understand is what the URL value should be for the pool, and I can't see a pattern in the examples and docs I've found on this. Here are my pool settings, at any rate:
Name: oracleTrufflePool
URL: myOracleServerName
Driver Classname: weblogic.jdbc.oci.Driver
Properties:
user=user
password=password
server=myOracleServerName
ACLName: user
Password: password
As you can see, I also don't understand whether the Oracle user name and password must be duplicated in the Properties section, or should they really only be listed in the ACLName and Password fields (in the Server Console UI)?
TIA,
Steve

Connection Pool Failure

Hello. I'm using wls 5.1 and Oracle 8i and an unable to make a connection pool. I keep getting the following with the message below. Where and how do I change my path?
weblogic.common.ResourceException: weblogic.common.ResourceException:
Could not create pool connection. The DBMS driver exception was:
java.sql.SQLException: System.loadLibrary threw java.lang.UnsatisfiedLinkError
'no weblogicoci36 in java.library.path'.
at weblogic.jdbcbase.oci.Driver.connect(Driver.java:116)

Hi,
You need to ensure that the ORACLE_HOME is set and PATH has
%ORACLE_HOME%\bin;%ORACLE_HOME%\lib;%WL_HOME%\bin\oci816_8 (check verison of
database) in the server startup script.
