Checkpoint question....
Once a checkpoint has occured all the blocks modified by transactions after that have to wait till the next checkpoint(or 3 seconds) for the DBW0 to write it to the disk. But, in one of the Oracle training materials for 1Z0-042 i read that, after a checkpoint has occured, some modified blocks may be written to the disk before waiting till the next checkpoint.
Is this possible?
DBWR writes,
every 3 secsI think that it'sLGWR that writes every 3 seconds not the DBWR.

I have a ACE checkpoint question. when u create a checkpoint to save the config on the ACE module where does the file get stored
HI,,
To display checkpoint information, use the show checkpoint command in Exec mode. The syntax of this command is:
show checkpoint {all | detail name}
The options and arguments are:
â¢all-Displays a list of all existing checkpoints
â¢detail name-Displays the running configuration of the specified checkpoint
For example, to display the running configuration for a specific checkpoint, enter:
host1/Admin# show checkpoint detail MYCHECKPOINT

Navigation issues with question slides in Captivate 6
In earlier versions of Captivate (5.5) we have always been able to insert question slides into our projects as checkpoints and allow the user to freely navigate through the project and answer the checkpoint questions as often as they like. We have also been able to provide success and failure feedback popups for those question.
In Captivate 6 we are seeing that question slides can apparently only be answered once and do not reset to be answered again the next time the user navigations to those slides. We want to allow the user to answer checkpoint questions as often as they like and we need to be able to provide success and failure feedback popups. We have tried every imaginable combination of setting with no success. Has anyone else been experiencing this or have a solution to this problem?
Thanks,
Vernon . . .When I run the same projects with the exact same settings side by side in Captivate 5 and Captivate 6, in the Cap 5 project I can navigate the project freely and answer the checkpoint questions repeatedly as often as I like. As I navigate the questions are reset and can be answered again every time I enter the question slides.
In Cap 6 the questions are locked after the first answer and cannot be answered a second time. Even stranger is the fact that when tested using only a subset of the slides adjacent to the question slide (next 3) it works and does appear to reset the question allowing repeated answers, but it fails when the entire project is run.
I have asked our other developers to test this and they are experiencing the same problem with their projects.
The only difference I can see between the two projects is that the Quiz results slide in Cap 6 cannot be deleted whereas it does not exist in the Cap 5 project ??? -
Checkpointing - control file contents question
Some clarification is needed if possible...
When you commit a transaction:
- commit scn is recorded in the itl of the data block and undo segment header
- lgwr records the committed scn (for all data blocks involved) to the redo log
Checkpoint Event
- (3 seconds or possibly less passes by) CKPT wakes up and signals DBWn to write dirty (modified and committed)
blocks to disk
- CKPT records the scn of those blocks in the control file (data file and redo thread sections) and the data file
header (task of checkpoint when a log switch occurs)
- Checkpoint position in the Redo Log is forwarded
Control file contents question:
When LGWR writes the commit scn to the redo log, who writes the scn to the control file? LGWR or CKPT?
Also, when is the redo thread scn written?
MattMatt,
This is my understanding of the stuff. Feel free to correct me.
Checkpoint SCN , as I mentioned in my last reply is the marker of the point till which the data is "chekpointed" to the datafiles. This marker tells the controlfile that in the case of the crash, where to start recovery of the datafile and have to go which extent in the redo stream? This is only available in the datafile header and in the controlfile. This doesn't get recorded in the redo log file/stream.
I mentioned checkpoint queue in my reply too. Though I couldn't find any reference directly mentioned between this and in the checkpoint SCN but I believe my theory , if not totall, partially is correct. The incremental checkpoint is the stuff which makes the decision that how many redo blocks needs to be applied to the datafile if its closed without a proper checkpoint. So this part is maintained in the Datafile header itself in the form of the checkpoint SCN. When not matched with the conrolfile checkpoint SCN, which is always higher than this, a recovery is reported.
I hope its somewhat correct. Do let me know your views too.
Cheers

Hi all,
I got one basic question regarding SSIS 2010 Package where source is Microsoft Excel 97-2005. I wanted to know How this package works in production where there is no Microsoft office or Excel driver installed. To check that there is excel driver installed
or not, I followed steps: Start-->Administrative Tools--> Data Sources(ODBC)-->Drivers and I found only 2 drivers one is SQL Server and another one is SQL Server Native Client 11.0.
Windows edition is Windows Server 2008 R2 Enterprise, Service Pack-1 and System type is 64-bit Operating System.
We are running this package from SQL Server Agent and using 32-bit (\\Machine_Name\d$\Program Files (x86)\Microsoft SQL Server\110\DTS\Binn\DTExec.exe /FILE "\\Machine_Name\d$\ Folder_Name\EtL.dtsx" /CONFIGFILE "\\Machine_Name\d$\Folder_Name\Config.dtsConfig"
/MAXCONCURRENT " -1 " /CHECKPOINTING OFF /REPORTING E) to run this package. I opened the package and tried to find out what connection we have used and found that we have used "Excel Connection Manager" and ConnectionString=Provider=Microsoft.Jet.OLEDB.4.0;Data
Source=F:\Fares.xls;Extended Properties="EXCEL 8.0;HDR=YES"; and source is ‘Excel Source’
I discussed with my DBA and He said that SSIS is having inbuilt Excel driver but I am not convinced.
Could anyone please clear my confusion/doubt?
I have gone through various links but my doubt is still not clear.

How Can I Get a List of the ODBC Drivers that are Installed on a Computer?
http://blogs.technet.com/b/heyscriptingguy/archive/2005/07/07/how-can-i-get-a-list-of-the-odbc-drivers-that-are-installed-on-a-computer.aspx
Thanks Shiven:) If Answer is Helpful, Please VoteHi S Kumar Dubey,
In SSIS, the Excel Source and Excel Destination natively use the Microsoft Jet 4.0 OLE DB Provider which is installed by SQL Server. The Microsoft Jet 4.0 OLE DB Provider deals with .xls files created by Excel 97-2003. To deal with .xlsx files created by
Excel 2007, we need the Microsoft ACE OLEDB Provider. SQL Server doesn’t install the Microsoft ACE OLEDB Provider, to get it we can install the
2007 Office System Driver: Data Connectivity Components or
Microsoft Access Database Engine 2010 Redistributable or Microsoft Office suit.
The drivers listed in the ODBC Data Source Administrator are ODBC drivers not OLEDB drivers, therefore, the Excel Source/Destination in SSIS won’t use the ODBC driver for Excel listed in it by default. On a 64-bit Windows platform, there are two versions
of ODBC Data Source Administrator. The 64-bit ODBC Data Source Administrator is C:\Windows\System32\odbcad32.exe, while the 32-bit one is C:\Windows\SysWOW64\odbcad32.exe. The original 32-bit and 64-bit ODBC drivers are installed by the Windows operating system.
By default, there are multiple 32-bit ODBC drivers and fewer 64-bit ODBC drivers installed on a 64-bit platform. To get more ODBC drivers, we can install the 2007 Office System Driver: Data Connectivity Components or Microsoft Access Database Engine 2010 Redistributable.
Besides, please note that 2007 Office System Driver: Data Connectivity Components only install 32-bit ODBC and OLEDB drivers because it only has 32-bit version, but the Microsoft Access Database Engine 2010 Redistributable has both 32- bit version and 64-bit
version.
If you have any questions, please feel free to ask.

Performance / stability issues with BDB 3.3.62 while checkpointing
Hi,
first of all: we use BDB 3.2 for more than a year within our application and we never had any performance or stability issues. Now we are about to release a new version of our software with BDB 3.3 and we found some problems during our release tests.
This is the situation: we have implemented some cleanup routines that make very heavy use of the BDB environment. The common usage pattern is to scan the database (about 300GB with >> 100 million items) and than delete a lot of items from the database. The first versions of our cleanup routine worked without any problem but during performance tuning of our code we suddenly and reproducible encountered segmentation faults in the com.sleepycat.je.recovery.Checkpointer thread. We analysed more that 10 VM crashes and ALL crashes were related to Checkpointer thread. (Linux 64 bit, JDK 1.5.0_013 / 1.6.0_06)
After we removed our performance tuning (only application logic – nothing BDB-related) the VM crashes disappeared – so it looks like some kind of problem which only occurs under high load conditions. Next thing we tried was enabling our performance tuning and setting Ceckpointer configuration to default (write a checkpoint after 20MB) before that we used time based checkpointing with 60 sec interval.
With Default Checkpointer configuration there were no VM-crashes but performance was very slow!
Finally my question: What Checkpointer configuration would you recommend for an environment that is under very high load with regard to delete operations? Would you recommend using “high priority Checkpointing”? Would you recommend time- or data-based checkpointing?
It looks like Checkpointing every 60 seconds was not a good idea but 20MB seems to be too slow.
This leads to another question: What does a longer Checkpointing interval mean for recovery time? Does recovery take substantially longer if checkpointing is done less fequently?
Any help would be very much apprechiated.
Here are two HS_ERR_PID

Question about versioning (history) in the latest release
Hallo,
Some questions:
1. Will versioning ever be integrated with locked pages, locked scene, colored pages, revision marks functionality etc, so that at a particular moment you can optionally augment the current versioning with the more traditional way of production revision cycles?
2. If above will not be the case (or is never activated): what currently happens with scene numbers & manual breakdown info that is already added, but than the scene gets deleted. Is all this info gone (& scenes renumbered). Can we save a version to keep this info? Please clarify.
3. Regarding breakdown of elements: will there be a way that we can visualize breakdown sheets on screen. It's much easier for me to look at it that way, e.g. the Scenechronize way (I guess I'm old).
4. Regarding breakdown and making the script 'production ready', will there be a way to combine scenes that belong together and part scenes (that are not in the same shooting location but where the writer chose to combine the action in one scene, eg like telephone conversation etc).
I guess all my questions boil down to this: will Story also aim to offer serious production breakdown features that could be used by production managers & assistant directors to prep for physical production, or will it mainly be a collaborative writing tool (even if it does allow you to transfer text into On Location shotlists and then eventually into your clips).
I guess there's a conceptual difference (at least when talking about narrative film with a lot of cast, locations, props etc): do you support mainly the writing effort and than transfer into a tool like Scenechronize once production starts - or do you go further? For (corporate) interview type shoots this matters less.
I would be interested to hear your views on the matter.
Regards,
BavoYes. Versioning will be integrated with locked pages, colored pages but we are not planning to lock scenes yet. We will also show asterix against changed lines in future updates.
You can always explicitly save a version (file->save as) to mark a checkpoint draft. You can add your own comments while saving this draft so that you can find it later.
We'd like to support production related features because we want to leverage script metadata for all it can be leveraged for. That said, "full fledged" is a loaded term. We will take small steps and enable workflows related to production as we go along. Dynamic breakdown reports, that can be viewed and edited in Story are on our roadmap.

Hi,
I have a Oracle 10.2.0.4 Standard Edition database with a manual physical standby on a remote server. To synchronize my stnadby, I'm forcing a log switch then I copy the archive log on the standby site for recovery.
I'm having several "Checkpoint not complete" in the alert log and I found the reason: when you switch the log, there's only an incremental checkpoint not a full one... so when I force the switch and the system wants to recycle the first log (the one where the last full checkpoint occurs), I'm getting the warning because the database must complete the checkpoint.
My question: Is performing a "ALTER SYSTEM CHECKPOINT" before my log switch the solution to my problem or is there a better way to do so?
Thanks
ChristopheHi Pavan,
I don't think there's any link with slow IO: as I said, the system is doing nothing and the archived logs are from 500K to 1.2M, with my redologs being at 50M.
For the FAST_START_MTTR_TARGET, I tested it with a value of 30 secondes and it does complete incremental checkpoint.
Here's an example of what is happening:
SQL> alter system checkpoint;
System altered.
SQL> select * from v$sysstat where name like '%background checkpoint%';
STATISTIC# NAME CLASS VALUE
166 background checkpoints started 8 2
167 background checkpoints completed 8 2
SQL> alter system switch logfile;
System altered.
SQL> select * from v$sysstat where name like '%background checkpoint%';
STATISTIC# NAME CLASS VALUE
166 background checkpoints started 8 3
167 background checkpoints completed 8 2
SQL> alter system switch logfile;
System altered.
SQL> select * from v$sysstat where name like '%background checkpoint%';
STATISTIC# NAME CLASS VALUE
166 background checkpoints started 8 4
167 background checkpoints completed 8 2
SQL> alter system checkpoint;
System altered.
SQL> select * from v$sysstat where name like '%background checkpoint%';
STATISTIC# NAME CLASS VALUE
166 background checkpoints started 8 5
167 background checkpoints completed 8 5I think, that in my case, the only option is to force a checkpoint before I force the switch to avoid the system to issue a "Checkpoint not complete" with all the transactions stopped while it complete the checkpoint.
Thanks

Thread 1 cannot allocate new log, sequence 714 - Checkpoint not complete
I'm working in a Oracle 10g database, running on RHEL. The alert_*.log file is putting out this type of text for the past few months:
Thread 1 advanced to log sequence 713 (LGWR Switch)
Current log#2 seq# 713 mem# 0: /dbfiles/..../onlinelog/filename.log
Current log #2 ..........
Thread 1 cannot allocate new log, sequence 714
Checkpoint not complete
Any ideas to get me pointed in the right direction is appreciated,
Thank you in advance,
WesThe immediate fixes Vishal suggests are the standard answer, but there is more to it, as the MOS doc he references shows. Additional questions I would ask:
How long is the delay between the inability to switch and when it actually switches? How many datafiles do you have? What is waiting in the db?
In general, I find making log files sized for the rare massive updates, then using the built-in timeouts to switch every 20 or 30 minutes (depending on management recoverability expectations), helps avoid some of these problems. More specifically, run a statspack or awr (if licensed) report for maybe an hour during heavy times, and see what it thinks the waits are. Tuning is an iterative process, and sometimes different things can cause similar symptoms. Sometimes fixing the biggest problem (which is often poor SQL) can radically change the symptoms observed. Other times you find you have dying hardware, or someone messed up a switch configuration. -
Thread 1 cannot allocate new log, sequence 1196,Checkpoint not complete
We were receiving the following messages in alert log. We have Oracle 10g R2 database having four redo log groups with two members each (50 MB). To overcome this error yesterday we added two more groups with same config. Again we received the same message in the alert log.

Checkpoint not completeYou might not want to revivify threads from 2006. Create a new thread, including all the information to make it a [url http://catb.org/esr/faqs/smart-questions.html]smart question. Which version and patch level of Oracle are you on, which platform, how often are your logs switching, a relevant clip from your alert log surrounded by {noformat}{noformat} tags, etc.

Checkpoint not complete + db_writer_processes/dbwr_io_slaves
Hi,
Oracle Database 11g Release 11.1.0.6.0 - 64bit Production With the Real Application Clusters option.
After I noticed this error into the alert log:
Thread 2 cannot allocate new log, sequence 152831
Checkpoint not complete
Current log# 17 seq# 152830 mem# 0: +ONLINELOG/evodb/onlinelog/group_17.272.729333887
Thread 2 advanced to log sequence 152831
Current log# 14 seq# 152831 mem# 0: +ONLINELOG/evodb/onlinelog/group_14.269.729333871
And read a lot to understand the real cause (for the moment I increased the the redolog file from 5 to 7 (250mb each)).
As it seems I've no problem with the ARCH processes, I read that the cause can be the DBWR0 process that is not "fast" enough to write block I've into redos, and free them for archiving.
I read then something about the asynchronous I/O, and how db_writer_processes/dbwr_io_slaves can simulate the async write to disk.
I think I understood the difference between db_writer_processes and dbwr_io_slaves.
My question is how I can understand if my database needs more DBWR process.
At the moment my configuration is:
db_writer_processes 1
dbwr_io_slaves 0
Thanks in advance,
SamuelHi Samuel,
There is still a major confusion on your side concerning the DBWR. It will NOT write data from your redo buffers to the redo logs, since it is the job of the LGWR.
When a log switch occurs (so, you will use a different redo group), then it is the job of the ARCn process(es) to backup the 'used' redo log to a archive log.
When your ARCn process(es) are not fast enough, and a log swicth occurs, it may happen that you have no inactive (read archived) redo group.... then Oracle 'hangs' till it can find such a redo group available.
So, you may want to add 1 (or more) redo group, or increase the size of the redo log files, or have more archiver processes.
DBWr job is to write dirty database blocks back to datafiles.
CKPT also works independently of the LGWR and DBWR.

Checkpoint occuring for every log transfer
Thanks for taking my question!
I have a new server and not much is running except exports, imports and rman backups. Problem is every redo transfer gets a checkpoint. Is this normal occurrence while doing backups and loads?
Thanks!
Kathie
My server is 11.1.0.7 windows 2008.
I have archive logging on.
I had 3 log groups with two members each.
redo size is 100m.
I just added a fourth group to see if that will help but it seems strange to get a checkpoint everytime the log transfers.

Laura,
Please don't take it as nitpick , this is just a little more elaborated view of what you said.Checkpoint is initiated with the log switch and keeps on getting completed. Oracle does it on its own pace. With log switch, checkpoint doesn't need to get completed but before thesae log is requested , it must be completed. I agree with You, I was just explaining that it's normal that it occurs and not going into details why there is message about Checkpoint not complete
But probably should have ... -
10.5.7 breaks CheckPoint SecureClient VPN
After upgrading to 10.5.7, my CheckPoint VPN client stopped working. I tried uninstalling and reinstalling the VPN client, however, re-installation does not work either.
Has anyone had a similar experience or a solution?I have a related but different issue.
I recently installed Checkpoint client latest version, and can connect to the remote network etc.
But nothing can connect to my mac from my local LAN, behind my firewall/router, even when SecureClient is not running. Doesn't respond to ping, can't ssh in from my laptop, etc.
nmap says the Mac Pro is invisible.
Little Snitch is installed but not active - besides, this is a problem incoming, not outgoing.
The Mac firewall is off.
I tried unloading the checkpoint kexts but they refuse.
Uninstalling makes things return to normal - connections happen fine with no other change.
So my question is -- is this expected behavior?
