We have a DTS package that is submitted every minute by a SQL Agent job (2000). We see instances where before the first job is completed, the second one starts running.
Has anyone encountered this type of behavior before?
In my application code I am trying to invoke multiple threads in which each thread is loading an instance of the same SSIS package and would initialize the package variables with different values and execute the different instances in parallel. In each thread - after the package execution has completed successfully - I read that instance's SSIS package variables to get result information from that Instance run.
When I load the same package in different thread using LoadFromSqlServer() method
- does the code create multiple instances of the SSIS package and load the distinct instances in each of the thread
- Will the Package Execution ID be different for the different instances?
- Are the package level variables instance safe?
I have a website running under Windows Server 2003 which I am trying to deploy Reportin Services to using a custom security extension using Forms authentication. There is also another website which is just a Report Server running on this IIS 6.
On my development machine, XP with IIS 5.1, the Website with Reporting Services using forms authentication works fine, shares cookies for authentication and all that jazz. but trying to configure a second instance of Reporting Services on Server 2003 is not behaving.
Is there some trickery or details involved with running two instances of Reporting Services?
Also in the Configure Report Server tool it is failing and so not initializing on the last step of the Database Setup

I am running multiple instance of the same application. This application is connecting to the database and running stored procedures using ADODB (all code examples are taken from msado15).
The problem is that somehow these two applications are sharing something either with the connection or commands.
For instance if the two instances are in the following function at the same time then they both thow an SEH exception:
Code Snippet
inline _RecordsetPtr Command15::Execute ( VARIANT * RecordsAffected, VARIANT * Parameters, long Options ) {
struct _Recordset * _result = 0;
HRESULT _hr = raw_Execute(RecordsAffected, Parameters, Options, &_result);
if (FAILED(_hr)) _com_issue_errorex(_hr, this, __uuidof(this));
return _RecordsetPtr(_result, false);
}
The exception that occurs is: "First-chance exception ...: 0xC0000005: Access violation reading location 0x00000068."
And afterwords when they go to release the command an error occurs on
First-chance exception at 0x4de4120c in IpsEngine.exe: 0xC0000005: Access violation reading location 0xcccccccc.
Code Snippet
inline void _bstr_t::Data_t::_Free() throw()
{
if (m_wstr != NULL) {
::SysFreeString(m_wstr);
}
if (m_str != NULL) {
delete [] m_str;
}
}
This is being called from.
Code Snippet
inline void Command15::PutRefActiveConnection ( struct _Connection * ppvObject ) {
HRESULT _hr = putref_ActiveConnection(ppvObject);
if (FAILED(_hr)) _com_issue_errorex(_hr, this, __uuidof(this));
}
The exception that occurs: First-chance exception at ...: 0xC0000005: Access violation reading location 0xcccccccc.
Similarly when one instance releases a command using
Code Snippet
inline void Command15::PutRefActiveConnection ( struct _Connection * ppvObject ) {
HRESULT _hr = putref_ActiveConnection(ppvObject);
if (FAILED(_hr)) _com_issue_errorex(_hr, this, __uuidof(this));
}
The second instance of the application fails when running the command at the exact same time.
Code Snippet
inline _RecordsetPtr Command15::Execute ( VARIANT * RecordsAffected, VARIANT * Parameters, long Options ) {
struct _Recordset * _result = 0;
HRESULT _hr = raw_Execute(RecordsAffected, Parameters, Options, &_result);
if (FAILED(_hr)) _com_issue_errorex(_hr, this, __uuidof(this));
return _RecordsetPtr(_result, false);
}
The command and connections are not static and there should be completely seperate instances of these for each instance of the application. Does anybody know why this may be happening. Any help would be appreciated. Thanks in advance.
I'm looking at installing 2008R2 and 2014 side by side, then using Mirroring to provide HA for the 2008R2 instance and AoHA for the 2014 instance. I'd be using the same two physical servers for both the Mirroring pair and the AoHA pair.
View 2 Replies View RelatedMy client has a server running MS 2003 Server for Smal Business Server, and it has SQL Server Express 2005 installed (I believe it is installed 3 times, as part of SharePoint, Veritas Backup Exec and ACT! applications).
I am trying to implement an application that uses SQL Server 2000, but the Server 2003 SBS does not support that version. So I need to launch an additional instance of SQL Server Exp 2005.
To do so, do I need to download and install SQL Server Express 2005 software again? Or can I just run SQLSVR.exe from an existing instance, but with a different instance name (sqlservr.exe -s<InstanceName>?
The reason I need another instance is that these existing instances limit DDL statements.
I am new to this and compare it to launching MS Word multiple times - you don't need to reinstall Word to run it multiple times.
Is launching from the command line a bad idea - and if it is, what is the better way to ensure that it launches under the local system context a service?
Thanks in advance for any help and insights. It is much appreciated.
A small question which may be stupid.
In Management Studio Express, one instance of Sql Express is running, with User Instances. This in indicated by a green circle with a white arrow head.
At the same time I'm connected to an instance of Sql Express on a Small Business Server. This server instance just has a white circle, but is also running. Is this normal.?

Hi,
I think this is a question for the specialists among us.
Can I use one general reporting server (installed on instance MAINREPORTING)
for multiple customers who all have their own sql instance (CUST1, CUST2, CUST3, ..)
I would use UserAuthenciation on the reportserver url to display the specific reports customers can use.
Is this possible, and what do i have to take care off concerning installation and/or configuration (especially on
the reporting side) ?

Hi all
We are planning to upgrade vom SQL 6.5 to SQL 2000 and SMS 1.2 to SMS 2.0. We want to first migrate SMS 1.2 to 2.0 with the SQL 6.5 database. Afterwards we want to install SQL 2000 as a second instance on the sql 6.5 server and migrate from there our databases. Is this the best way to do this? Does anybody have experience with running two instances of different SQL-Versions on one server? and what kind of trouble can I expect to run into?
Any tips & tricks are welcome
Thanx

Hello,
I want to enumerate all the RUNNING SQL instances[in a mixed env where SQL 2000 and SQL2005 are deployed] using SQL DMO.
But any of the following methods would not help
ListAvailableSQLServers Method
ListInstalledInstances Method
because they list all the installed instances and while my intent is getting only the running instances.
Is there any other direct API ? Pls advise.

View 12 Replies View Relatedi have sql server 2005 express running. during install, i had issues with a system dll that i found answers online and resolved. i am still very green, but i know much more now than i did at the time. i believe that as a result of the partial then failed installs i have multiple instances either fully or partially installed. when i am in the sql server mgmt express environment, it lists two sql engines. i only ever use one, and would like to safely remove the second without damaging or corrupting anything done with the other instance.
my reasons for wanting to do this are twofold. first, i would like to free up the drive space taken up by the second instance. (i am a stickler for clean harddrive mgmt and maintenance). second, now that i have used the software and am somewhat more familiar with it, i would consider installing a second, intentional instance so that i may attempt to better customize some of the install-time settings and configurations.
can anybody give me any pointers/ guide me in the direction of information on how to SAFELY go about this?
thank you in advance for any help.
I created a second SQL2000 instance on a Windows 2000 server. The strange thing is that I can create an ODBC connection to the default instance but cannot for the new named instance. If I try from a client that has SQL installed on it, I can see both instances. Any idea why this is happening?
Thanks,

We're trying to decide if we should use a single large instance of SQL Server or multiple instances on the same server. This is for a dev environment.Have to limit max RAM per instance so no instance grabs it all.There will be I/O contention and CPU contention between instances since the different instances won't coordinate with each other.It limits the available RAM for In-Memory tables..It sets lower limits to the amount of RAM available for any given query, causing artificial "contention" even when there's nothing else running at the time.

I am running SQL 7.0 as the default instance and SQL 2K as a named instance. Each is using a different port....7.0 is using port 1433 and 2K is using 1024. Everything appears to be up and running fine on the server. However, I am not able to access the 2K instance from a client. I have tried to use both TCP IP and named pipes setting them up using the server network utility and the client network utility. No luck anywhere. I continue to get connection errors...check network documentation...
ANY IDEAS??????
Currently, I am running SQL Server 2000 with the default instance. I know SQL2K can run up to 16 instances simultaneously. I would like to add another instance but am unable to find documentation on how to add it. Books online tells me "about" multiple instances, but not how to set it up. I've obviously missed something somewhere. Can someone please direct me to a document that will help explain "how" to add another instance?
Thanks for your time and your help.
I have a need to add a second Sql instance to an existing cluster. However I read in this article http://www.sql-server-performance.com/articles/clustering/clustering_best_practices_p1.aspx
that this is not recommended. Does anyone know why this is or what problems I may encounter?

Dear Listers,
1.) Is it possible to install Analysis Services on multiple SQL Server 2000 instances? If it is, then can you instruct me as to how to perform the install. If it is not possible, then does one restrict access to cube data via the Database Role Manager?
ie. The host box is - DOILAB30 with Analysis Services & SP2
Instance - DOILAB30/DOILAB30_FIN (Can AS be installed here?)
Do I severely restrict the membership of OLAP Admins?
2). Re. AS maintenance. - How do I backup and restore OLAP dbs/cubes etc. Following a restore, what issues, such as cube users/permissions should I be aware of? (if any).
TIA

I have two instances installed on my server. I have one database on the default instance and two very large reporting databases on the other instance.
Will having the default instance running affect the performance of the non-default instance where my reporting databases are?
