Check point occurs

What will happen check point occurs
Regards,

Basically this:
1. All dirty blocks are written from DB cache are written to the data files.
2. The latest SCN is written into the data file header.
3. The latest SCN is also written to the control files.
part of that process you can pick up from the Oracle manuals "Concepts, Process architecture"
I remember I saw more detailed ppt from someone like Steve Adams or Julian Dyke, but can't remember where it was exactly.

NET8의 LOCAL NAMING METHODS 이용관련 CHECK POINTS & TROUBLESHOOTING

Net8의 Local Naming Methods 이용관련 Check Points & Troubleshooting
====================================================================
Net8 관련 내용중 Local Naming Methods(sqlnet.ora와 tnsnames.ora
를 이용해서 DB에 Connect하는 방법)에 관한 일반적인 Check Points 및
Troubleshooing 사항을 정리해보도록 하겠다.
[Client Connection : Local Naming Methods]
1. Local Naming method resolves service names by using the local configuration files tnsnames.ora and sqlnet.ora.
2. One of the benefits of the Local Naming method is that it provides a simple method for resolving service name addresses. It is easy to configure local naming by using a GUI called the Net8 Assistant. When you configure a client machine for local naming by using the Net8 Assistant, a tnsnames.ora file is generated. To configure all the other client machines on the network that need to use the same database services, you can simply copy this file to the client machines.
3. Another benefit of using the local-naming method is that it resolves service name across networks running different protocols.
[Local Naming : Configuration]
1. The local-naming method resolves service names by using the information configured and stored on each individual client. Local naming is most appropriate for simple distributed networks with a small number of services that change infrequently.
2. Local naming requires the configuration of two local files, tnsnames.ora and sqlnet.ora. The tnsnames.ora file contains the address needed to direct a connection request to the specified listener on the specified node by using the specified database. The sqlnet.ora file stores information about the selected naming method.
3. Local naming is easy to configure by using the Net8 Assistant. The Net8 Assistant is implemented in Java and is packed with the Java Runtime Environment. You can run the Net8 Assistant on any platform on which Net8 is installed.
4. When you configure an Oracle8 server to use the local-naming method for service names resolution, the client-side configuration files tnsnames.ora and sqlnet.ora are automatically generated. After the configuration is complete, you copy these two files from the server to the client machines.
[Client Files : Parameters]
1. The tnsnames.ora and sqlnet.ora files are generated at the default location ORACLE_HOME\net80\admin.
2. The first parameter in the tnsnames.ora file specifies the service name and the domain name for the client.
3. The tnsnames.ora file contains a parameter called DESCRIPTION. This parameter contains information about the connect descriptor for the client.
4. The ADDRESS parameter in the tnsnames.ora file specifies the network address of the host to which the client is connected. If multiple addresses are specified, use the keyword ADDRESS_LIST before the ADDRESS parameter.
5. Another parameter in the tnsnames.ora file is the CONNECT_DATA parameter. This parameter specifies the SID of the database to which the client is connected.
6. The DEFAULT_DOMAIN parameter of the sqlnet.ora file specifies the domain from which the client most often requests names. When this parameter is set, the domain name is automatically appended to the service name in a connect string.
7. The DIRECTORY_PATH parameter is another key parameter of the sqlnet.ora file. This parameter specifies the names resolution method to be used for the client-server connection.
8. The sqlnet.ora file also contains a parameter called DEFAULT_ZONE.
This parameter specifies the region to which the client belongs.
[Troubleshooting the Client Side]
These are common client-side problems and the error messages associated with
each error code.
ORA-12154: "TNS: could not resolve service name"
ORA-12198: "TNS: could not find path to destination"
ORA-12203: "TNS: unable to connect to destination"
ORA-12533: "TNS: illegal ADDRESS parameters"
1. The ORA-12154 error occurs when Net8 cannot locate the connect descriptor specified in the tnsnames.ora configuration file. To solve this problem, first verify that a tnsnames.ora file exists and is accessible. Next, verify that multiple copies of the tnsnames.ora file are not present. After checking the existence of the tnsnames.ora file, verify that the service name specified in the connect string is mapped to a connect descriptor in the tnsnames.ora file. Verify also that the file does not contain any syntaz errors. The ORA-12154 error also occur if there is more than one copy of the sqlnet.ora file. Verify that duplicate copies of the sqlnet.ora file are not present.
2. The ORA-12198 and ORA-12203 errors occur when the client is unable to find the required database. To solve this problem, first verify that you have correctly entered the service name that you want to use. Next verify that the service name parameters in the ADDRESS section of the connect descriptor in the tnsnames.ora file are correctly defined. Then, verify that the tnsnames.ora file is stored in the correct directory. The ORA-12198 and ORA-12203 errors can also occur if the listener on the remote node is not running. Verify that the listener on the remote node has started and is running. If the listener is not running, start the listener by using the Listener Control(LSNRCTL) utility.
3. The ORA-12533 error occurs if the protocol-specific parameters in the ADDRESS section of the designated connect descriptor in the tnsnames.ora file are incorrect. To solve this problem, use the correct protocol-specific parameters in the ADDRESS section of the connect descriptor.
4. The ORA-12545 error occurs when the listener on the remote node cannot be contacted. This may happen if the values of the ADDRESS parameter in the tnsnames.ora file and the listener.ora file are incorrect. In this case replace the incorrect values with the correct values in both the files. The ORA-12545 error can also occur if the listener on the remote node is not
started. To verify whether or not the listener is started, determine its status with the STATUS command of the LSNRCTL utility. If necessary, start the listener on the remote node with the START command.

Check point in fund management for budget and creation of po

I have a Budget for a perticular expenses say Rs 100000/-, so the po should not be created for more than Rs 100000/- as per the budget. but the po is been created for more than the budget amount.
pls. let me know where the check point has to be maintain.
Thanks

Moderator: Please, search SDN

Hi ,
First of all as a primary step you can do the following :
1. is the commitment item getting derived in the PO.
2. Is the commitment item non statistical ( means you have not put the tick on statistical commitment item ) in FMCIA .
3. check the budget amount via the report FMRP_RW_BUDCON for the budget amount and released amount .
Hope this would help .
Cheers ,

Performance tuneup for a special DB (disable locking, check-pointing,...)

Hi,
I have simple database contains key/value records. The program is a multi-thread application that iterate over records. Each worker thread read a record and after some calculations, replace it. The records are completely independent from each other. The following is my DBController class that share between all threads.

If you are writing and you need to recover in a reasonable amount of time after a crash, you need checkpointing.
If multiple threads may access a record concurrently, you need locking.
If you need good read performance, you need as large a JE cache as possible.
If you want to tune performance, the first step is to print the EnvironmentStats (Environment.getStats) periodically, and read the FAQ performance section. Try to find out if your app's performance is limited by CPU or I/O.
If you are reading records in key order, then you'll get better performance if you also write them in key order.
I'm not sure why you're using a TupleBinding to do Java object serialization If you want Java serialization, try using a SerialBinding.

App server check Points

Hello Guys
Can any one pass on a document that will explain what are the check points that to be monitored on a daily basis for a Application Server?
We have several issues where users are complained about load balancing / Citrix / connection issues ?
If any one can pass me a document about the health check of any server, area where we need to monitored / mindful on a daily basis.
Thanks
BI

Hi,
When you are speaking about user logs, what logs are you reffering?
BPC logs, Citrix logs, Windows logs?
for BPC logs you can use the follow note:1328702
User profile path is define into Citrix when the installation was perfomed.
Person which perform the installation of CITRIX server can provide you this information.
Kind Regards

I want to know the main areas which may get affected due to Patch-up.
Regards

Hi,
Pls keep go thru the new features that were introduced thru this patch level. Make note of the Bugs SAP has fixed with this service pack.
Keeping in view of the features and bug fixed keep track of the areas that you need to keep track of.
Its is also important to check for below things.
1. Master Data - Materials, Vendors and Users.
2. Transactional Data - SC's, PR's,PO's Confirmations, Invoices.
3. Workflow.

From where did you get this error, as you said you have went through the SQL errorlog & no issues reported, then it is not related to the SQL database server, Also as you said it is 3rd party tool, then suggesting to check what that 3rd party tool it is
for & where it configured & for what(like monitoring,application level query etc) & what inside described it.

Check Point 620 Wired Appliance: Real World Throughput and Experiences

I am considering a purchase of the Check Point 620 wired appliance. If you have used the 620, I would like to request some help:
1. What real-world throughput have you seen with all blades active? The internet speed at our site is 120 Mbps
2. What has your experience been -- good and bad? Anything notable?
Thanks!

Check Point VPN-1 SecureClient

I've successfully installed Check Point's VPN-1 SecureClient. How do I invoke the connection to the remote PC? What's the OS X equivalent to Windows' mstsc? (I'm new to Mac.) Thanks.

The CheckPoint VPN-1 Secure Client software is only compatible with Mac OS v 10.3 (Panther). I had the same issue and am waiting for CheckPoint to update the software.

Check Point VPN

I successfully installed Check Point VPN software and was able to connect but the policy update hung up.
I elected to uninstall via the uninstaller option in the application.
The uninstaller hung up but seemed to uninstall. The menu bar icon disappeared.
I have been unable to reinstall the software from a new download. The installer seems to run successfully but no application appears in the Applications folder after rebooting.
Any suggestions as to what might prevent reinstall?

Thanks for the reply.
I found an installer in the Library as suggested.
The installer did not install successfully.
I trashed the installer, repaired permissions, downloaded the software again and was able to install successfully.
I will not be able to test the connection until I am off the network but I am better off.

Check Point VPN and local wireless network

I need to use Check Point VPN to access a client's remote network. Now I cannot access my wireless printer or AirPort base station, even when I have disconnected and shutdown the Check Point client. I have removed the Check Point startup items from LaunchAgents and LaunchDaemons in order to restart without Check Point loading at start up.
When I start in Safe Boot I can access the printer, but not with a normal start up. How can I find the other startup items that are interfering with my local wireless network?
Am running Mountain Lion.
