Managing Partitions: exclusive access?

I have a partitioned table, each partition has 2 subpartitions except for CPART0 which has 1 subpartition.
For this example, assume each partition holds a days data and we have 5 partitions (we have many more depending on volume and number of days stored)
Partitions: CPART0 - CPART4
Subpartitions: keep and other
CPART0 < monday CPART0_keep This partition always holds old data we need to keep for awhile.
CPART1 < tuesday CPART1_keep CPART1_other
CPART2 < wednesday CPART2_keep CPART2_other
CPART3 < thursday CPART3_keep CPART3_other
CPART4 < friday CPART4_keep CPART4_other
When data comes in for friday, we want to drop tuesday but merge data in CPART1_keep subpartition
with CPART0_keep subpartition. We then add a new partition CPART1 with a high value < saturday
The keep subpartitions always get rolled into the cpart0keep partition.
What we do (using Pro C/C++) is:
alter table archive drop subpartition CPART1_other;
alter table archive merge partition CPART0 into CPART1;
alter table archive rename partition CPART1 to CPART0;
alter table archive rename subpartition CPART1_keep to CPART0_keep;
for 6 indexes:
alter index .. rename partition CPART1 to CPART0;
alter index .. rename subpartition CPART1_keep to CPART0_keep;
alter table archive modify subpartition CPART0_keep rebuild unusable local indexes.
alter table archive add partition CPART1 values less than ( saturday ) tablespace xxx;
In doing some volume testing we are seeing that the "rollover" of data will take 5 - 20 minutes.
My question is whether exclusive access is needed to do the alter table commands above.
We did get this error once when trying to prepare the rename partition statement:
ORA-00054: resource busy and acquire with NOWAIT specified (-4)
I had to manually fix and add the new partition.
Is exclusive access needed for 'alter table rename' ? What about drop, merge or add partition?
If it is the renames that need exclusive access, we can probably just not do any renames.
( the 1-subpartition old data can rotate thru CPARTx partitions )
Can we insert data in partitions not involved in the "rolling over" while the rollover to a new day is
in progress? What about queries?
thanks for any help or comments,
Lisa

OWA is not good enough because OWA doesn't notify you when there is a new email message. If the partners only had OWA, they would miss lots of time sensitive emails and meeting reminders and we don't want to forward the messages and attachments to
their other email address.
OWA does notify you when a new email arrives. It even makes the message arrival sound.

Can you set a single FILEGROUP to READONLY without getting exclusive access to the entire DB?

I'm in the process of building a partitioned table with a sliding-window partition. I have several years of historical static image data that will be moved to individual filegroups created to hold year's worth of data each. The Business
requires that the last 60 days of images be updateable, everything older needs to be readonly which simplifies the backup process.
Since the PRIMARY filegroup is always READWRITE, I'm going to use the PRIMARY filegroup for the upper range of my partition to allow users to make necessary modifications to images in this 60 day window. On a nightly basis, I'm going to run
a process that changes the upper range on the partition to the daterange = (getdate() - 60). The 61st day moves seamlessly from PRIMARY filegroup to my 2013FileGroup in milliseconds.
The process runs almost flawlessly, however, I'd like to change the FILEGROUP to READ-ONLY after moving the data to the archive partition. In my process, I can quickly switch this archive filegroup to READWRITE and run the Partition MERGE \ SPLIT to
change my upper range and move records between partitions. However, I cannot change the FILEGROUP back to READ_ONLY without getting exclusive access to the entire database to save the change.
Is there any way to set a single FILEGROUP to read-only quickly without setting the entire DB to SINGLE-USER with ROLLBACK IMMEDIATE? I've tried the WITH ROLLBACK IMMEDIATE on the ALTER DB statement to modify the filegroup without any success.
I need WRITE access for a matter of seconds before setting it back to read only. Any help would be greatly appreciated.
I'm dealing with a TB of data, a full restore could take 60+ hours to recover the entire db. However, doing partial backups on the READWRITE portion of the DB is done quickly and I can get the business back online quickly by recovering the
PRIMARY filegroup and then restore readonly filegroups in the background. If I can't change these filegroups to read-only on the fly, I may have to maintain more backups for extended periods of time and may need to wait for maintenance windows to set
filegroups to READONLY.

Is there any way to set a single FILEGROUP to read-only quickly without setting the entire DB to SINGLE-USER with ROLLBACK IMMEDIATE? I've tried the WITH ROLLBACK IMMEDIATE on the ALTER DB statement to modify the filegroup without any success.
I need WRITE access for a matter of seconds before setting it back to read only. Any help would be greatly appreciated.
I am moving it to Tools. Consider setting up a separate database for the 60+ days data.

If you don not have any process running on your pc that uses your database like Enterprise Manager or any other third party application, use
SqlConnection.ClearAllPools();
in C# code before restoring. Like the following code:
Code Snippet
public void BackupAndRestore(string Query)
     SqlConnection.ClearAllPools();
SqlConnection connection = new     SqlConnection(ConfigurationManager.AppSettings["ConnectToMasterDB"]);
     SqlDataAdapter da = new SqlDataAdapter();
     da.SelectCommand = new SqlCommand();
     da.SelectCommand.Connection = connection;
     da.SelectCommand.CommandText = Query;
     da.SelectCommand.ExecuteNonQuery();

Operations Manager Failed to Access the Windows Event Log and management server is showing warning state

Hi,
I am monitoring AD server from SCOM 2012 R2. My management server goes into waning state. When i run Health explorer then it come back in the healthy state but after some time it again goes into warning state. After seeing alert i found that a alert is coming
again and again i.e. Operations Manager Failed to Access the Windows Event Log.The description of alert is mention below
The Windows Event Log Provider is still unable to open the DhcpAdminEvents event log on computer 'nc2vws12ad5.corp.nathcorp.com'.
The Provider has been unable to open the DhcpAdminEvents event log for 64080 seconds.
Most recent error details: The RPC server is unavailable.
Please suggest me how to resolve this so that my management server will again come back in healthy state.
Thanks
Abhishek

Hi Abhishek,
As i mentioned earlier the Alert resolution says the same points.
Can you give details on the below ?
Is there really a log named "Dhcpadminevents" in the MS's Event viewer ?
Did you recently configure any new alert where you mentioned "Dhcpadminevents"
as a event log location ?
If yes then what is the target you selected for the rule / monitor there ?
Can you post the results for analysis ?

ESYU: R12 - Order Management를 위한 Multi Org Access Control(MOAC) setup 방법

Purpose
Oracle Order Management - Version: 12.0 to 12.0
Information in this document applies to any platform.
R12의 Order Management에 대핸 Multi Org Access Control(MOAC) setup 방법에 대해 알아본다.
Solution
일반적인 MOAC Setup:
1. HRMS에서 Security Profile을 정의:
a. HRMS Management responsibility 선택
b. HRMS Manager> Security> Profile로 이동
c. Security Profile이 정의되어 있는지 확인 (OM responsibility 혹은 Site level로)
d. 만일 아직 setup 되어져 있지 않다면 Operating Units를 입력
e. 저장
Note: 만일 위 d step과 같이 새로운 security profile을 생성하였다면 concurrent program 'Security List Maintenance'를 꼭 실행해야 한다.
그렇지 않으면 multiple operating units가 OM forms의 LOV에 나타나지 않을 것이다.
이 program은 multi-org access를 validating 하기 위해 사용하는 table에 data를 생성한다.
Navigation: HRMS Management> HRMS Manager> Processes & Reports> Submit Process & Report> Security List Maintenance
2. MO Profile Options setup:
a. MO: Security Profile - 이 profile setting은 MOAC functionality를 활성화 한다.
b. MO: Default Operating Unit - 이 Operating Unit는 OM forms과 report에서 default가 될 것이며, 이를 clear 하거나 변경하기 위해 LOV를 사용할 수 있다.
Keep the MO profiles in sync:
MO: Security Profile은 site와 responsibility level로 setting 할 수 있다.
MO: Default Operating Unit은 site, responsibility, user level로 setting 할 수 있다.
Application이 원하는대로 동작되지 않는것을 발견하면 이 profile options의 setting 값을 확인한다.
3. OM setup:
R12 upgrade 시 OM Profile에서 migrate 된 새로운 OM System Parameters를 확인:
Order Management Super User> Setup> System Parameters> Values
(See <<NOTE 393646.1>>-R12 Readiness Cheat Sheet: Migrated OM Profile Options)
4. Form에서 hidden field 'Operatin Unit'를 활성화시키고 default folder로 저장:
Sales Order and Order Organizer forms
Quick Sales order and Organizer forms
Sales Agreement forms
Pricing and Availability form
Other forms
Note: Sales Order form에서 hidden field 'Operating Unit'를 'Show' 하기 전에 fotm안에 이 field를 위한 공간을 만들어 놓아야 한다.
예를 들면 Customer Number field를 짧게 하거나 Operating Unit field로 이 field를 덮어씌울수 있다.

Hi Larry,
Have you considered adding the exec apps.mo_global.set_policy_context call to your connection's start-up script?
Tools -> Preferences -> Database -> Filename for connection startup scriptNot the most flexible approach, so I'm not sure if it is appropriate for your application, but just a thought. You might create distinct connection names with different start-up scripts for each org_id.

There is enough space on the site server and the site server has full control over the source directory. I wish I can give you more information but I'm hoping this is enough info to get some assistance. If more information is needed please let me know!

We usually give the DP's computer account and the site server computer account read access to these shares in our environment.

Using the Security Manager to restrict access to a single package

After reading up on the Security Manager, the package.access property and the use of the [accessClassInPackage RuntimePermission|http://java.sun.com/javase/6/docs/technotes/guides/security/permissions.html#RuntimePermission] , it seemed to me that it would possible to set up the following: I have a security-sensitive code base packaged in a jar, and I want to make sure that only one client code base that I specify is permitted to access it. The idea here is to prevent malicious code from executing anything in the sensitive code base; the sensitive code is only accessible to one client that I name in a security policy file. Perhaps rather foolishly, I advised a client to consider this before testing out a sample myself, because much to my surprise, it appears to me that it isn't possible to get the Security Manager to do this at all. Am I missing something? I'm a bit startled by this conclusion -- it seems like such an obvious use for the Security Manager, I'm hard-pressed to be believe that it can't be done, and more inclined to suspect that I'm going about it wrong.
Here's what I thought I could do: set up the package.access property so that it denies access to any package; then in the policy file, grant the RuntimePermission/accessClassInPackage to the client code base that is permitted to access the sensitive code.
Of course, you wouldn't want the package.access property to exclude all packages in the global java.security file, because then no code could be accessed at all. It would be necessary to use the trick of resetting the package.access property within the code, as [illustrated in the secure coding guidelines|http://java.sun.com/security/seccodeguide.html#1-1a] .
But the problem lies in the idea of "use the package.access property to deny access to +any+ package". There doesn't seem to be any way to use wildcards or the like with the property -- it has to specifically name packages (or package prefixes) to which access is forbidden. It wouldn't do to try to name the packages to which I'm trying to prevent access, since we're trying to prevent access from malicious code -- the attacker could just choose package names that aren't on the list. I'd really need to say that access is denied to all packages, except for those in the permitted code base, but the security mechanisms for package access don't seem to allow that.
Moreover, the trick of changing the value of package.access can't be done within the client code -- otherwise, the attacker client would just set the property to his own purposes. But it can't really be done within the sensitive package either, because the whole idea is to prevent access to that package, and by the time it's busy setting the property, it's already too late, because the package has to have been accessed by a client to get there at all.
It seems to me that this a symptom of something I've never really understood about the design of the Security Manager -- you can grant permissions to specific code bases, but you can't revoke permissions from specific code bases, let alone all code bases. What I want to do here is grant access permission to one specific code base and revoke it from all others. There doesn't seem to be any way to express that with the mechanisms of the Security Manager.
The more I look at it, the more it seems that there's just no way to use the Security Manager this way -- set up package access so that a specific code base can only be accessed by one specific client code base. There are surely other ways to get the effect that I'm looking for, but as far as I can tell, none of them involve restricting package access (for example: define a custom permission, grant it only to the permitted client. and check against that permission within the sensitive code base; meaning that the sensitive code has to be accessible to anyone in the first place). This conclusion really surprises me (not to mention my bit of embarrassment with the client); wouldn't this be precisely the sort of thing the Security Manager ought to be good for?

You're looking at this back to front. The security policy file is there for the client to decide how much access he is going to give this application, not for to application to restrict who can use it. If you want to control what used to be called 'state orientation' you can do that directly by looking down the stack trace inside your code.

Swap Error: Windows Azure is currently performing an operation on this deployment that requires exclusive access.

When swapping our deployments for a web role, we are receiving an error, "Windows Azure is currently performing an operation on this deployment that requires exclusive access." We have been waiting patiently for over 48 hours and the error
persists. We have deployed/swapped many times before without issue. The dashboards do not show any known Azure issues at this time. We are stuck with an out-dated deployment.
We have deleted the staging deployment and tried again and it still does not work. It appears to be an issue with the production deployment.
Other threads state to create a support ticket. So we have attempted to do so with the following scenario: We are a BizSpark Plus partner and have MSDN tickets available to use for support. It bites that we have to use 1 for this Azure
issue. However, it appears you can't use MSDN support tickets for Azure as each time you go to create a ticket, it kicks you back to Azure to force the purchase of an Azure support plan...??

If you have the MSDN support plan, please contact their local Global Customer Service center for assistance in creating a Azure support case.

Error: Windows Azure is currently performing an operation on this hosted service that requires exclusive access.

Hello,
We are creating 2 cloud services in parallel with one deployment(VM Role) in each cloud service. For both requests (Sometimes only on 1) we are getting the following 409 Conflict error as a response to create hosted service POST request:
409 ConflictError :
Windows Azure is currently performing an operation on this hosted service that requires exclusive access.
On getting the exception we have a cleanup call and in retry we are trying to create again. On each retry we are using a new cloud service name.
The error occurs few times, every time we invoke the creation of 2 cloud services with VM in parallel. And on 2-15 retries, its getting created successfully. However when we invoke 1 cloud service creation with VM, we are not seeing this error.
Not sure why this error is thrown during simultaneous creations. Any help would be greatly
appreciated.
Thanks.

Hi Sowmya,
We are using the REST APIs for all our operations – Edit:
Creating two cloud services with one virtual machine (IaaS) each having
two different deployment IDs.
Step by Step procedure for creating the services:
1.
Create an Affinity Group
2.
Create a Virtual Network
3.
Create Hosted service
4.
Create Deployment (VM Role) under that hosted service
Step 3 & 4 are executed concurrently for two different VM Creation where it is failing with 409 Conflict error.
Also, the two cloud services are being deployed under the same Virtual Network and same Affinity Group. Apart from this there are no shared resources
between two cloud services.
Please let us know if you have more queries.
Thanks.

Exclusive Access To The Database

Is there a way for my code to know if I have
Exclusive Access To The Database? If so, what would the
Compress Database Command be?
Application: I would like my update script to include a command to compress the database, when no one else is in the database.

Hi Mark,
>> Is there a way for my code to know if I have Exclusive Access To The Database?
I think you could check whether the Access is exclusive with vba code, some key code as below:
Function IsCurDBExclusive () As Integer
' Purpose: Determine if the current database is open exclusively.
' Returns: 0 if database is not open exclusively.
' -1 if database is open exclusively.
' Err if any error condition is detected.
Dim db As Database
Dim hFile As Integer
hFile = FreeFile
Set db = dbengine.workspaces(0).databases(0)
If Dir$(db.name) <> "" Then
On Error Resume Next
Open db.name For Binary Access Read Write Shared As hFile
Select Case Err
Case 0
IsCurDBExclusive = False
Case 70
IsCurDBExclusive = True
Case Else
IsCurDBExclusive = Err
End Select
Close hFile
On Error GoTo 0
Else
MsgBox "Couldn't find " & db.name & "."
End If
End Function
For more information, you could turn to the link below:
# ACC: How to Determine If a Database Is Open Exclusively

Build PAS Model - Cannot get exclusive access to model

Hi all!
I am receiving "Cannot get exclusive access to model" when we generate Build PAS Model from CubeBuilder.
This is the environment info:
OS: Red Hat Enterprise Linux Version 5.4
Product: SSM 7.5 SP09 HotFix 03 (working in SAP Netweaver CE 7.1 SP5 for MaxDB)
DB: MaxDB 7.6
I create CBDEFAULT model connection, ODBC DSN SSM_CB_EA and SSM_CB_EA LINKDID, as per instructions in the install and config guides.
All except the cube builder is working fine, even though after receiving the error y verified in my SSM Administrator that the Model Connections were
correctly defined, my cube was named "CLARO" so the connection was automatically created as CBCLARO_MM and CBCLARO_SC, we tested connection and all was ok.
I suspect about the ODBC for linux, for that instance, I install unixODBC and configure, but the problem persist. In my test, we verified that the user root
and smpadm (smp is my instance name) the ODBC connection works fine, however, I configure the SYSTEM DSN however I was unable to verify it.

Exclusive access to a stored procedure

Hi all,
I've the following question:
Is it possible to set an exclusive access for sessions to a procedure in the DB?
So if session A enters the procedure and runs for example a loop or something like that and then session B comes and needs to enter the same procedure, it has to wait till session A finished and left the procedure.
If it is possible, how?
Thanks in advance.

> If it is possible, how?
It is called serialisation - forcing a resource (a procedure in your case) to service only a single caller at a time.
The means used to protect a resource to (for example) force serialisation is called a semaphore. There are numerous technical definitions for a semaphore. But they all imply the same thing. Apple calls it "A programming technique for coordinating activities in which multiple processes compete for the same kernel resources."
In Oracle, you can typically do this using DBMS_LOCK (as already stated). However, DBMS_LOCK is classified as a system procedure and by default, user/app schemas should not have access to it.
There is a very easy alternative to DBMS_LOCK - using Oracle's own default row locking.
This approach works in the following fashiion.
You create a dummy table (it will never contain any committed rows and only serve as the "semaphore device").
create table semaphore( id number primary key ) organization index;
To force serialisation, the very first step in the procedure is to insert a row into this table using a unique id for that procedure. E.g.
insert into semaphore values( UNIQUE_ID_FOR_MY_PROC );
A second (or 3rd/4th/etc) copy of the procedure will be blocked on its INSERT. It will wait for the 1st INSERT to be either committed or rolled back.
The procedure does its thing. Right at the end, it issues a:
delete from semaphore where id = UNIQUE_ID_FOR_MY_PROC;
This will still block the 2nd copy of the procedure. As soon as the 1st process now issue a COMMIT, the 2nd copy will continue and it will insert successfully into the SEMAPHORE table.
What I like about this approach is that any failure in the procedure, will result in ROLLBACK (either implicitly or explicitly). The ROLLBACK will remove the INSERT on the SEMAPHORE table and the 2nd copy of the procedure will now be able to continue.
Of course, it make sense not to do the INSERT and DELETE manually against the SEMAPHORE table, but instead use a PL/SQL package that does this for you. This way you have a nice wrapper API that can be extended to include more features.

Central Management Store being accessed is not the active store

We are experiencing issues with our Lync 2013 services after hardening our SQL backend. Even though we have created aliases to the backend database instances and FrontEnd servers is able to access the databases, we are having this error when performing tasks
like enable-csuser or new-clientpolicy from powershell or Lync control panel:
###50023:XdsPublishItems: The central management store being accessed is not the active store. No data can be read or any changes can be made to this store.
Any suggestions or ideas?

Here some guidance that must be followed for Lync Servers

A client made a DirSync LDAP request for a directory partition. Access was denied due to the following error

We started getting this error when we installed Lync Server. I already verified that the "RTCHSUniversalServices" group has “Replicating Directory Changes" permission.

Domain Controllers and Lync server are running on Windows 2008 SP2. Any other things that I could check?
