any suggestion?

PS2013 - When creating a new instance of Project Server hangs in 'Waiting for resources' status

Hi,
I have one instance of Project Server 2013 fully operational and I tried to duplicate the instance to make some tests. As I know the issue of using the same Content Database of Project Server in the same Server Farm, I used the powershell backup/restore/dismount
and mount the content database to change the site IDs to avoid index duplication. The Project server database was a regular SQL backup and restore in another database.
I created a new Web App in the port 90 as show below.
Then I included the Content database of Project Server as separated DB from SharePoint for this new SharePoint -acme90 and I tried to create the new instance. The creation hanged in "Waiting for Resources" status.
To make another check excluding the reuse of the SharePoint-80 I tried to create another instance both in the SharePoint-80 where is the working instance and in the SharePoint-90, everything default and again they all hanged in Waiting for Resource.
If I try to create the instance using PowerShell I got the following error:
PS C:\Users\epm_setup> Mount-SPProjectWebInstance -DatabaseName Test_EPM -SiteCo
llection http://acme02/epm -Lcid 1046
Mount-SPProjectWebInstance : Cannot find an SPSite object with Id or Url:
http://acme02/epm.

    + FullyQualifiedErrorId : Microsoft.Office.Project.Server.Cmdlet.PSCmdletM
   ountPwaInstance
All SharePoint and Project Server services are running, all App Pools and sites are started at the IIS. I could not find a hanging timer job.
I cannot stop the hanged process or dismount the instances using Powershell since no instance created.
How should I solve the hanging status of creation of the instance? As they are in Hyper-V I can go back using one snapshot.
Thank you.
Best regards, Ricardo Segawa - Segawas Projetos / Microsoft Partner

Hi Eric,
Thank your for your interest in this case.
I checked for running and crashed PWA jobs and deleted all of them just after restoring the snapshot and tried to create the new instance in the new web app in port 90 (besides the existing and working instance in port 80), but again it hanged in "waiting
for resources". There is not any timer job hanging, no error in event viewer or in log. So the error is well before working with cloned dbs.
Answering your questiion, I am working all on 2013. My intention is backup one instance of the port 80 and copy to the instance of port 90, changing of course the url and the index of the content db of SharePoint. The process I used was:
Create a new web app in port 90, creating a new SharePoint_Content_2 on a
http://server:90 site.
Created the top level site called Portal using the Team Site template.
Create a new content db for new instance of Project Server named EPM_Content_2 using Central Admin.
Backup content db from port 80 instance of Project Server and restore to this EPM_content_2 using PowerShell cmd.
Dismounted and mounted this Project Server content db to create new index for existing sites to avoid index conflicts.
Backup the Project Server DB from port 80 using SQL backup and restored as ProjectWebApp2 db for port 90 instance.
Tried to create a new instance of Project Server
http://server:90/pwa on web app of port 90 using the ProjectWebApp2 db and using the same app pool of the other instance. But as in the previous case, it hang out in "Waiting for resources".

Weblogic server hangs during stress-testing -- possibly EJB deadlocks

Hi
While running stress tests on our application, our WLS 4.5.1 hangs even at a
mere load of 20 users. We are running on a Solaris machine. Database: Oracle
8.1.5, running on the same machine. Using oracle.jdbc.driver.OracleDriver as
the JDBC driver, and using JTS as the transaction manager.
When we did a thread dump (complete lis at the end of this post) and
basically we are seeing a bunch of our entity beans in a "locked" state. A
common pattern we see in the thread dumps is that
[1] weblogic.ejb.internal.BaseEJBContext.lock(BaseEJBContext.java:180)
[2] weblogic.ejb.internal.StatefulEJBCache.bind(StatefulEJBCache.java:250)
[3]
weblogic.ejb.internal.StatefulEJBObject.getContextForInvoke(StatefulEJBObjec
t.java:88)
[4] weblogic.ejb.internal.BaseEJBObject.preInvoke(BaseEJBObject.java:164)
[5] com.nps.ers.ejb.organization.<Our Entiy Bean>EOImpl.<a get
method>(ERSSystemConfigurationBeanEOImpl.java:1539)
[6] com.nps.ers.ejb.awardnomination.<Our entity bean>.<some method>
After more thorough studying of EJB transactions, we changed the isolation
level of all our beans from TRANSACTION_SERIALIZED to
TRANSACTION_READ_COMMITTED and made sure all our beans say TX_REQUIRED for
their transactionAttribue. Still, this problem persists.
The basic scenario we are load testing is that of multiple users logging
into the system and trying to access a particular user's record, and right
now, this is causing deadlocks at 20 users.
What we fail to understand is that --
(a) even if a method is attempting a read-only access to the data, why would
it try to obtain a lock? or why would it matter that the data is locked?
Some of the locks we are seeing are actually on a bean that is used for
read-only purposes.
(b) if 2 or more processes are trying to access the same record, based on
whichever process got their first, shouldn't one succeed, and the other go
into a 'waiting' state?
We have also opened this issue with weblogic support, and the response so
far has been that there "may" be a bug in weblogic 4.5.1 itself that's
causing it, and they need to look into it further. Other similar posts in
the newsgroup haven't been resolved either -- hence this general plea for
help. Please advise if you've any suggestions. Thanks
Sandeep

Can you post details on this instrumentation?
I know in the past when we ran into this type of problem, it took us a while
to think through and identify the problems.
Thanks,

Generally this indicates a deadlock in the order that you access your
entity beans. Please follow-up with [email protected]. There is
some instrumentation that you can turn on to help spot why this is
occurring.

Hi
While running stress tests on our application, our WLS 4.5.1 hangs even
at a
mere load of 20 users. We are running on a Solaris machine. Database:Oracle
8.1.5, running on the same machine. Usingoracle.jdbc.driver.OracleDriver as
the JDBC driver, and using JTS as the transaction manager.
When we did a thread dump (complete lis at the end of this post) and
basically we are seeing a bunch of our entity beans in a "locked" state.A
common pattern we see in the thread dumps is that

method>(ERSSystemConfigurationBeanEOImpl.java:1539)
[6] com.nps.ers.ejb.awardnomination.<Our entity bean>.<some method>
After more thorough studying of EJB transactions, we changed theisolation
level of all our beans from TRANSACTION_SERIALIZED to
TRANSACTION_READ_COMMITTED and made sure all our beans say TX_REQUIREDfor
their transactionAttribue. Still, this problem persists.
The basic scenario we are load testing is that of multiple users logging
into the system and trying to access a particular user's record, andright
now, this is causing deadlocks at 20 users.
What we fail to understand is that --
(a) even if a method is attempting a read-only access to the data, whywould
it try to obtain a lock? or why would it matter that the data is locked?
Some of the locks we are seeing are actually on a bean that is used for
read-only purposes.
(b) if 2 or more processes are trying to access the same record, basedon
whichever process got their first, shouldn't one succeed, and the othergo
into a 'waiting' state?
We have also opened this issue with weblogic support, and the responseso
far has been that there "may" be a bug in weblogic 4.5.1 itself that's
causing it, and they need to look into it further. Other similar postsin
the newsgroup haven't been resolved either -- hence this general pleafor
help. Please advise if you've any suggestions. Thanks

Connect To Server Hangs Before Prompting For Name And Password

Hi Everyone.
Connect to Server hangs for 25 seconds before prompting for name and password.
I am trying to access a share on a Windows 2008 R2 domain controller via a Mac running 10.6.8 (Snow Leopard) using SMB.
Example: smb://192.168.101.11/sharename
Once connected, browsing is fine - it's just the connecting that takes a long time.
I have specified port 139 and login name, I have disabled IP6 on the Mac, the Mac and Windows 2008 server are on the same LAN and are wired.
Again, once connected, browsing is fine - it's just the connecting that takes a long time.
Any help would be appreciated.
Damian

Something to add ...
Connecting to a Windows 2008 stand-alone server outside of the domain (e.g., workgroup) does not have the same problem - the name and password prompt shows immediately.

Weblogic 6.0 : Server hangs while reading a https request

Hi,
I'm running WLS6.0 on Win2000. The server hangs for some requests sent over https,
unless it times out. It seems that the server is not able to read the complete request
from the socket. It somehow thinks that there is more data available and keeps on
waiting. Is this a bug?
Also, it works fine if i change the url from a https to a http one. So, is this
related to SSL implementation of weblogic?
Has any of faced a similar problem? Thanks in advance for any ideas/thoughts on this
problem,
Thakur.

Also, it works fine if i change the url from a https to a http one. So, is this
related to SSL implementation of weblogic?
Has any of faced a similar problem? Thanks in advance for any ideas/thoughts on this
problem,
Thakur.

Best practice for GWT testing?

I was wondered what is the best way to test my GWT client logic which calls into my server and processes the results. I don't want to have to have a server running for these tests? That will come under my functional/performance testing. Is there a way to mock a server ?
Specifically some code like
String url = "localhost:8080/myApp/login";
RequestBuilder builder = new RequestBuilder( RequestBuilder.POST, url );
builder.sendRequest( "My data String", new MyResponseHandelr() );How should I test this without there being a service available at the given URL, but instead have a means where by I can send specific data back to the client code under test?

The unit testing support of GWT does not work for you?
http://code.google.com/webtoolkit/doc/latest/tutorial/JUnit.html
If not, running a server might be the only option you have. Perhaps JBoss Arquillian can help you there.
http://www.jboss.org/arquillian
Arquillian supports Jetty as a container for example, which boots really fast.

PS2013 - Creating a new instance of Project Server does not run and hangs in "Waiting for Resource"

Hi,
In my Project Server 2013 environment I created an instance of Project Server which is running in a notebook Hyper-V Windows 2012 Server with 11 GB, 4 threds, 3 GHz, one box configuration with complete version of SQL Server 2012 with SP1, nothing trial.
PS and SPS 2013 updated with Cumulative Update of Dec 2013.
I want to create a new empty instance in the same port 80 with a different URL or in the port 90 creating a new web application.
Whatever option I choose, when I try to create the instance of the Project Server it hangs in "Waiting for Resource" status. No Event Viewer, no hanged timer Jobs, all services running, all pools and sites started and I found out nothing in the
SharePoint Logs. After every attempt I return the server snapshot to the former state.
The Project Server and SharePoint continue to work normally.
Any hints where should I look to solve this issue?
Thank you.
Best regards, Ricardo Segawa - Segawas Projetos / Microsoft Partner

Ricardo,
so, the only clue I can find in your posting is around the web application.
if you want a 2nd PWA instance on the same web application (this presums you have one already, working, right?).
all you really have to do is give it a different "pwa" name - like "Test" or some such and use a unique project database name : Test_ProjectServerData
there is much more you could do, for isolation into a private content database for example.
to use a different port, then you need to setup a web application on a different port and proceed as above, selecting that web app to start from.
if the basic action of new pwa site provision is not working, then it may suggest there is something systemmically wrong with the setup.
let us know,
Thanks, Eric S. Pcubed

Can we Install SQL Server Express with Advanced Services x 64 bit for our testing purpose without procuring any license? Also can we use it for commercial use if we are neglect risk sof using it on Production?

Can we Install SQL Server Express with Advanced Services x 64 bit for our testing purpose without procuring any license? Also can we use it for commercial/Production
use if we are agree to take risk of using it on Production?

Hi,
Yes you can, but you should be aware of the limitations of MS SQL Express version.
1. 1GB RAM
2. 10 GB database size per database excluding log file (SQL 2008 R2 and above)
3.Job Scheduling service is not available with SQL Server Express.
4.Data import and export feature is not available with SQL Server Express.
5.Limitation on number of CPU
Refer following article for features supported by different editions of MS SQL Server.

Power Bi for o365 - Odata connection test worked but "The server encountered an error processing the request. See server logs for more details". Port 8051? Authority\System

We set up the Data Management Gateway and created a new data source (odata to SQL via sqL user)
Did a connection test and it was successful!
Tried the URL (maybe it needs more):
https://ourdomain.hybridproxy.powerbi.com/ODataService/v1.0/odatatest
That resolves to some :8051 port address and then spits out this message:
The server encountered an error processing the request. See server logs for more details.
I checked and the data management gateway is running.
Does that 8051 port need to be opened on our firewall for this server? How can I confirm that is the issue.. I see no event on the server indicating this is the issue?
I am seeing this event:
Login failed for user 'NT AUTHORITY\SYSTEM'. Reason: Failed to open the explicitly specified database 'PowerBiTest'. [CLIENT: IP of the Server]

O365,
Is this still an issue?
Thanks!

Which is better for performance Azure SQL Database or SQL Server in Azure VM?

Hi,
We are building an ASP.NET app that will be running on Microsoft Cloud which I think is the new name for Windows Azure. We're expecting this app to have many simultaneous users and want to make sure that we provide excellent performance to end users.
Here are our main concerns/desires:
Performance is paramount. Fast response times are very very important
We want to have as little to do with platform maintenance as possible e.g. managing OS or SQL Server updates, etc.
We are trying to use "out-of-the-box" standard features.
With that said, which option would give us the best possible database performance: a SQL Server instance running in a VM on Azure or SQL Server Database as a fully managed service?
Thanks, Sam

hello,
SQL Database using shared resources on the Microsft data centre. Microsoft balance the resource usage of SQL Database so that no one application continuously dominates any resource.You can try the
Premium Preview
for Windows Azure SQL Database which offers better performance by guaranteeing a fixed amount of dedicated resources for a database.
If you using SQL Server instance running in a VM, you control the operating system and database configuration. And the
performance of the database depends on many factors such as the size of a virtual machine, and the configuration of the data disks.

Server, it was advised that the best approach is to study for all three exams rather than one at a time as there's a certain amount of overlap.
My question is does this apply to SQL Server 2012 too? Or would it be bets to study for, and take, the three exams separately and one at a time? I'm just completing the Trainsignal (now Pluralsight) SQL Server 2012 Administration Essentials 28-video course
and was just about to begin going through the equivalent book when I read the blog post.
My background is mainly in desktop/server support (10years following an IT degree) and before now, have had no real exposure to SQL Server. I was asked about a year ago by my current manager to "keep an eye" on the SQL instances we have and began
by replicating the our fail-over cluster in a virtual environment for testing purposes and to gain an understanding of the set-up. I've since developed a keen interest in SQL Server and plan to get certified...
Many thanks in advance.
Marcus.
Exams are:
1
Querying Microsoft SQL Server 2012
2
Administering Microsoft SQL Server 2012 Databases
3
Implementing a Data Warehouse with Microsoft SQL Server 2012

Hello,
My humble recommendation is to study for each exam one at a time. I found 70-461 most difficult exam of SQL Server I have
taken to this date for its XML content and the extent of the exam. Go for 70-461 first.
You will find tips and recommendations on the following Channel 9 resources:
http://channel9.msdn.com/Events/TechEd/Europe/2013/EXM15
(70-461)
http://channel9.msdn.com/Events/TechEd/Europe/2013/EXM16
(70-462)
Hope this helps.

Can dw cs3 connect directly to sql server database without a testing server?

I'm new to dreamweaver but have used script tools that link
directly to my sql server database.
Not in dw, so far. As of this early stage, I don't have or
want to use a web server, and it's blocking me
without one. I just want to prototype without a testing
server, directly to my database. And while I'll try php
later, I didn't want to have to get into it or cold fusion,
etc. right away.
Can dw connect directly to sql server database without a
testing server?
I'm running XP sp 3 at this point, and don't see IIS. There's
probably some security issues
I'll have to tangle with. The goal is for my website to end
up on the company intRAnet, not the www.
fwiw, I can Build in Data Link Properties and get a
successful test to my sql server database via
Microsoft Data Link, but once I go back and try the test in
OLE DB Connection it balks on the testing server,
as I don't have one locally or otherwise. Isn't there a way
to link to db without a testing server?
Thanks for any insights.

Yes, you can. However, Dreamweaver's PHP server behaviors
work only with
MySQL. To connect to any other database, you need to hand
code
everything yourself.

Using HA SQL server For 3rd Party SQL Access

Is it possible to use the HA SQL server as the access point for SQL stored proceduers on a link
server instead of the production SQL server. IPCC 4.0

you can try it out and see if it works however with 4.x we have observer memory leak which crashes the boxes.
Moreover as this type of scenario has not been tested by Cisco - TAC will state you to remove the setup before troubleshooting.
Hope this helps

The PL/SQL command (select/update) was hanged for long time

We have a proc program to access a 160 rows table (F_TRDATA), however, it always hanged for a long time, then it was retarted by our defence process.
(1)Table structure:
SQL> desc F_TRDATA;
Name Null? Type
SCP_NBR NUMBER
A_INDEX NUMBER
A_BITMAP LONG
SQL> select index_name, column_name from user_ind_columns where TABLE_NAME='F_TRDATA';
INDEX_NAME
COLUMN_NAME
I_F_TRDATA
SCP_NBR
I_F_TRDATA
A_INDEX
(2)Use DBLINK between two different machines:
LONG rtc;
char f_tabname[100];
EXEC SQL BEGIN DECLARE SECTION;
char srvname[100];
char dblink_name[100];
EXEC SQL END DECLARE SECTION;
sprintf(srvname,"%s",(const char*)STRING(INOBJECT::srvname).ToUpper());
EXEC SQL SELECT DB_LINK INTO :dblink_name FROM ALL_DB_LINKS WHERE OWNER=:srvname;
     db.setLastSqlCode(sqlca.sqlcode);
     if (sqlca.sqlcode!=0)
          TRACE("SELECT DB_LINK error "<<sqlca.sqlerrm.sqlerrmc)
          return VAL_ERROR;
     else
          TRACE("SELECT DB_LINK OK");
sprintf(f_tabname,"F_%s@%s",(const char*)STRING(parent->getClassName()),(const char*)STRING(dblink_name));
TRACE_SHOW(f_tabname);
rtc=get_free_ri(f_tabname);
EXEC SQL COMMIT;
(3)get_free_ri ():
memset(s_ln,0,800);
sprintf(s_ln,"SELECT A_BITMAP FROM %s WHERE A_INDEX=:a AND SCP_NBR=:b \
          FOR UPDATE OF A_BITMAP",tab);
EXEC SQL PREPARE S FROM :s_ln;
if (sqlca.sqlcode)
{TRACE(""<<s_ln);
TRACE(""<<sqlca.sqlerrm.sqlerrmc);
EXEC SQL DECLARE C_FREE_RI CURSOR FOR S;
if (sqlca.sqlcode) {TRACE("DECLARE C_FREE_RI : "<<sqlca.sqlerrm.sqlerrmc)};
memset(s_ln,0,800);
sprintf(s_ln,"UPDATE %s SET A_BITMAP=:a WHERE A_INDEX=:b AND SCP_NBR=:c",
     tab);
EXEC SQL PREPARE S FROM :s_ln;
EXEC SQL EXECUTE S USING :bitmap,:rand_ind,:scp;
