Log file in project online
Hallo,
I Need crate a log file which will contain all transactions made by project online users.
how can i do that.
Hello,
It depends what level of detail you are after? You could exact the Project Server queue log each day if you using the APIs, you could create a console app that runs on a windows schedule task and uses the PSI to exact the queue details. An simple example
of this for on-premise using PowerShell and the PSI can be seen below:
https://pwmather.wordpress.com/2012/03/05/projectserver-2010-2007-high-level-audit-export-via-powershell-msproject-ps2010-epm/
You would just need to probably move this to a console app and get the authentication working for Project Online and the PSI - all doable.
Alternatively if you wanted more details than what goes via the queue services, you could create you own remote event receivers for Project Online to capture the details.

Importing existing project to Project Online
Hello, my company recently purchased Project Online to add to our existing Office 365 environment.
From the Project Web App home page, I would like to use the Create or Import projects tile to add an existing .mpp project file that I have uploaded to my SkyDrive to Project Online, and manage this project from the Project Web app.
However, I cannot figure out how to do this or if it is even possible. The tile itself says "Create new or import from Sharepoint sites and project files.". To import an existing project you're then referred to this site: http://office.microsoft.com/en-us/project-server-help/more-ways-to-create-or-import-projects-HA102923810.aspx.
On that site the only listed ways of importing an existing project are to import a Sharepoint task list (not what I want) or by connecting your local Project Pro to Project Online and publishing the project.
Importing or uploading an existing project file directly to Project Online would seem to be a fundamental basic usage of Project Online. Do I really need to also purchase Project Professional in order to import existing project files to Project Online?
ThanksProject Online cannot read mpp files, hence the reason for requiring Project Professional 2013 if you want to import these into Project Online - even if you only want to manage them via Project Web App from then on.
If you've not got Project 2013 Pro, you could cut and paste the existing task list from Project into a SharePoint list, and create the project from there.
The way forward will depend on the complexity of your schedules, remember that PWA does not have all of the capability of MS Project 2013

You mean you have taken an online backup and lost all your archive log files after that online backup?

To perform a recovery with an online backup you will need all archive log files until the end of the online backup. If you have lost them you are not able to recover (or open) your database in a consistent state.
So the only suggestion we can do is:
You need the archive log files that were created during the online backup to perform an incomplete recovery ... if they are gone you can not restore your database.

Log4j misinterpretation - log files
Hi,
I have 2 applications running in my weblogic domain say TestDomain.
I am using Weblogic 9.2 patch3 version.
1) ABC.*ear* where one of the jar located inside APP-INF/lib/log4j-1.2.13.jar
2) Xyz.*war* where one of the jar located inside WEB-INF/lib/log4j-1.2.13.jar
I have 2 log4j porperties
1) abc_log4j.properties where name of the log file configigured */project/logs/abc.log*, RollingFileAppender
2) xyz_log4j.properties where name of the log file configigured */project/logs/xyz.log*, RollingFileAppender
abc.log file writes properly for sometime by the ABC.*ear* and then writes in to the xyz.log
Xyz.*war* writes log info properly into the xyz.log ONLY
What is the issue, how to resolve using weblogic 9.2 patch3 version?

Edited by: narayana on Dec 12, 2012 1:26 AMHi,
I think it causing due to miss classpath.
I would say to implement prefer-web-inf with in weblgoic.xml file and place the properties files out of the classpath and try to again.

Moving the online redo log files to different location
We just installed few more drives into our sandbox system and I want to move the online redo log files for better performance. We've got the SAPARCH directory moved to a different location.
Does anyone know how/where I can change the parameters so redo log files are pointed at different drives? It's not in the <b>init<SID>.ora</b> file...
Regards,
SumitHi Sumit,
The following link contains information about moving the redo logs:

Online redo log files being removed physically
Grid Infra version: 11.2.0.4
RDBMS Version: 11.2.0.4
Although this is a RAC DB, this is not a RAC-specific question. Hence posting it here.
Few months back, I remember issuing a command similair to below (DROP LOGFILE GROUP ...) and the redo log files were still physically present in the diskgroup.
If I remember correctly, the file is not deleted physical so that we can use the REUSE functionality (ALTER DATABASE ADD LOGFILE MEMBER '+REDO/orcl/onlinelog/redo1b.log' reuse to group 11; ) ie. you can use the REUSE command to add the logfile of the same name which is physically present in OS Filesystem/Diksgroup to redo log group.
But today, after I issued the below command, I checked the diskgroup location from ASMCMD
SQL> alter database drop logfile group 31;
Database altered.
From ASMCMD, I can that the file has disappeared physically. Is this a new feature with 11.2.0.4 or am I missing something here ?
ASMCMD> ls +DATA/msblprd/onlinelog/group_31.548.833154995
ASMCMD-8002: entry 'group_31.548.833154995' does not exist in directory '+DATA/msblprd/onlinelog/'Just to add to what Aman has said.
It is a bad practice not to let OMF decide the placement of Online redo logs because of this issue especially when you use ASM.
Executing rm command in Linux/Unix is easy but Dropping ASM aliases in the disk group can be a hassle.
This is documented.
"When a redo log member is dropped from the database, the operating system file is not deleted from disk. Rather, the control files of the associated database are updated to drop the member from the database structure. After dropping a redo log file, ensure that the drop completed successfully, and then use the appropriate operating system command to delete the dropped redo log file."
http://docs.oracle.com/cd/E11882_01/server.112/e25494/onlineredo.htm#ADMIN11324
BTW . You don't even need to set db_create_online_log_dest_n to enable OMF for ORLs.
SQL> show parameter log_dest
NAME TYPE VALUE
db_create_online_log_dest_1 string
db_create_online_log_dest_2 string
db_create_online_log_dest_3 string
db_create_online_log_dest_4 string

Physical Standby Online Redo log files,
Hi,
I'm trying to create a physical standby database (10.2.0.3). I'm a little confused about the requirement for online redo logs on the standby.
in my standby alert log I get the following when I issue:
SQL> alter database recover managed standby database disconnect from session
"ORA-00313: open failed for members of log group 1 of thread 1
ORA-00312: online log 1 thread 1: '/appl/oradata/prod/prod_1_redo_01_02.log'
ORA-27037: unable to obtain file status
SVR4 Error: 2: No such file or directory
Additional information: 3"
/appl/oradata/prod/prod_1_redo_01_02.log is the path to the location of the online redo logs on the production system. This file does not exist on the standby filesystem so the error is correct.
I assume that it gets this information from the standby control file I created on the production system and copied over to the standby.
Do I need to copy the online redo logs from the primary over to the standby site or do I need to create online redo logs on the standby?
Does the standby need to have redo log files?
I'm not talking about 'standby log files' of the type created using 'alter database add standby log file'. I've not got that far yet.
I just need to establish if a physical standby requires online redo log files?
Thanks in advance,
user234564I wanted to update this thread since I've been dealing with the exact same errors. The basic question is: "does a physical standby need the online redo logs?"
Answer: Not really, until one wants to switchover or failover (and become a primary database). Furthermore, whenever the MRP process is started, Oracle prepares for a possible switchover/failover by "clearing" the online redo logs (MetaLink note# 352879.1). It is not a big deal, since Oracle will build the actual redo files when the "alter database open resetlogs" is accomplished during a "role transition."
In our situation, we have decided to use our standby for nightly exports. We stop MRP, open the database read-only, then restart MRP. We built these standby DBs with RMAN. The RMAN duplicate process will not build the online redo log files until the database is opened for read/write (with resetlogs). However, we haven't had a need for read/write (i.e. a switchover).
Thus, every morning we have been getting the same errors that "user234564" posted above. At first the errors seemed scary, then we realized they were just a nusiance. In order to clean things up, all I did was just "cp" our stanby redo logs (SRL) into our online redo directories ensuring the names matched what was in v$logfile. When I restarted MRP, the alert log clearly showed Oracle clearing these "newly found" online redo logs. -
Commit Completes although current online redo log file have been removed.
Although i have removed current online redo log file in linux os (Oracle Linux),when i type "commit" it says that "commit complete".
Is this fair for this princip?*:" if Only when all redo records associated with a given transaction are safely on disk in the online logs is the user process notified that the transaction has been committed."*
I think that it can lead to loss of data in some cases..I'm using Oracle 11g R2 on OEL (x64)..
Can anyone explain me ? I'm getting stuck in this situation..
P.S : I haven't multiplexed current ORL group files...Javid wrote:

In *nix, a file that is open by a process isn't really deleted until the process that has it completes. So even though you 'deleted' a redo log, oracle is still holding it. As soon as you stop your database (maybe even as soon as the db does a log switch) the redo will really be gone and no longer available. consider the implications for archive logging.
P.S : I haven't multiplexed current ORL group files...You need to fix that. the online logs are the achilles heel of the database. That's why it is standard practice to multiplex them. -

As you can see from the above output at the database level everything is fine. So why during backup it is giving me warnings in DB12. Any help with this regard will be appreciated.

Accidently Deleted Online Redo Log Files
Dear friends
Just to give a try, I deleted online redo log files from the disk after clearn shutdown (In Test Environment Not A Production Database), then i started the dabase, I know we need atleast two online redo files for database to work properly. now my point of question is how can i create new online redo files ?
I have 2 redo logfile groups each with one member. In group 2 i have added new member for the deleted one using add logfile member ....... to group 2. but when i try todo the same to add logfile member to group1 I am not abale to do so. because its saying that this is the current logfile member. then I tried manual log switching to use next logfile member but database is not allowing as the database is just mounted not opened. plsease if any body helps me out to sort out this problem it will be a great help.

rC6Exv3hello ur instruction u have is some what bit rite. but i was not able to solve the problem
finally i solved the problem with these commands after database is mounted
recover database until cancel Enter
then I select the cancel option when it provide the user with the options
after cancelling the recover i issued the following command
alter database open resetlogs;
this method sorted out my problem
anyway very very thanks for ur root hints from where i got the Idea to recover online redo logfiles
Thank u very much -
Purpose of ONLINE REDO LOG FILES - Media or Instance recovery or BOTH ?
Hi
Currently studying this topic for the 1z0-031 exam and am a little confused.
my books (from instructor led class) say
-redo logs are a mean to provide redo transactions in the event of a DATABASE recovery
-redo log buffer gets flushed to redo log files to provide a recovery mechanism in case of MEDIA FAILURE
Then it says
-Online redo log files are used in a situation such as an INSTANCE FAILURE to recover uncommitted data which has not yet been written to the data files
- online redo log files are used for RECOVERY only.
Am i misunderstanding? Or are redo log files for both MEDIA and INSTANCE recovery? Or just INSTANCE ?
confused....
AmanjitOnline Redo Log Files are used in a sense for both Media and Instance Recovery. If your database is in NoArchive Mode then you will only be able to use the Redo Log Files for instance recover. But if you are running in Archive Log Mode then Redo Log Files are archived and will allow you to recover from media failure.

What is online redo log files???
Dear All,
I m bit confused with redo log files.what is need of back up of redo log files?????As i m new in the Basis please tell me i always get confused with redo log files and archive files.
Thanx and reagard's
AshokIn Oracle you have a number of online redo log files.
In an typical SAP installation you have two directories:
origlogA and origlogB
origlogA contains online redo log 1 and 3 and
origlogB contains online redo log 2 and 4.
In most installation you also have mirrlogA and mirrlogB, which the name tells, is mirrors of origlogA and origlogB.
Now, the online redo logs are circular,
so when 1 gets full oracle jumps to number 2.
At the same time oracle's archiver process starts to copy
online redo log number 1 to a file on disk.
This files are also known as archive redo logs.
In an recovery situation you might do with just the online redo logs,
but usually a combination of both online and archive redo logs is needed.
During database backup, you also backup the online redo logs
You also need to backup (backup twice then delete) archive redo logs.
the archive redo logs are your way back from the restored database to the last transaction of the database.
If one archive redo log is missing, you have to stop you recovery there and loose the rest of the transactions done in the database. -
Project Online - Timesheet Auditing - where do we read the log?
Where are the Timesheet Auditing logs maintained?
I can retrieve a bunch of Timesheet data with this query -
https://MyProjectOnlineTenant.sharepoint.com/sites/pwa/_api/projectdata/TimesheetLineActualDataSet() – but not sure if these are the audit logs or not.Spot on Paul - looks like either the option shouldn't be there for Project Online or we should have an OData feed - I'll try and find out which is the case - but suspect the former.
Best regards,
Brian

I found this in the oracle docs:
"Oracle Database uses only one redo log files at a time to store redo records written from the redo log buffer. The redo log file that LGWR is actively writing to is called the current redo log file."this is where it confuses me actually. I also thought about 2 nodes writing to 2 online log. But when I was querying gv$log, I saw 4 CURRENT entries.
