Hibernate & Standby not working on Portege 2000

I've recently bought a refurbished Portege 2000. It did not come with any documentation or Toshiba software installed. I've grabbed what I saw fit from the download section of the support page and have installed.
I've got the Toshiba console working, the accessibility utility and the Intel performance thingy. Power saving works now and so do all the hotkey functions apart from Standby and Hibernate (FN + F3/F4).
Have I missed something from the download section or is there a particular order to which I should be installing?
Thanks in anticipation,
Coastal

Hi
At first we should clear the operating system question I assume you use Win XP.
Am I right? Did you install the right Power saver utility for Win XP?
Two different Power saver utilities are available on the page; 5.04.00 and 5.01.00.
I would recommend using the latest one!
The other FN keys work correctly and therefore it looks like the important applications like common modules and Hotkey utility were installed correctly.
I think its only a setting issue. The Hibernation is disabled as default setting.
If you want to use the FN + F4 you have to enable it firstly in the power saver settings.
The same should be done with standby mode which can be used with FN+F3

Yet another standby question...

Hi gurus,
Please help to resolve the quiz. I have completed manual physical standby installation. It is up and running. I then decided to install Grid Control and to use Data Guard for the standby creation. I've successfully installed GC, deployed all agents, I can see my previous standbys, life is good in short. Now, when I am trying to create the second standby for my production database using the Data Guard I stuck on a logical question:
On the step 3 of Data Guard standby creation, there is a note, saying:
The instance name (also referred to as the SID) must be unique on the standby host.
Yeah, fair enough. But i can't understand what should I do next? I have:
db_name YELLOW - primary prod
db_name YELLOW - standby prod 1st
and i need db_name YELLOW - standby 2nd
But I can't create it on the same server where the first standby resides.. What options do I have? Do I need to create the second standby on another server? Do I need to kill 1st standby? Is there any way to avoid this conflict? I am confused. I have no equipment for TWO standby servers... I thought I can install there up to 9 standbys.. But it seems to be a problem.. And definitely, I cannot give my second standby other name than YELLOW as all my applications are strongly tied on db_name...
Friends, please clarify this if you can. I am kinda lost in here..
Thanks as usual,
Maria

well, that's a good question! :)
because I don't have spare server for the standby. the question is not about: 'should I or should not put more than one standbys in one server' , but more about: 'is there any way to put two standbys with the identical db_names in one server'. I know that I probably sound unprofessional, but I just wanna know.. If the answer is 'no way', I will kill the first standby then and recreate the second one using DG with the correct name.
Thanks for writing to me,
M.

Standby question

Hi experts , i have a simple question ..Can we convert a logical standby to physical standby ? Yes or No, if yes how .. if no please let me.. please help

Yes or No, if yes how .. if no please let me.. please helpNo, that is logically impossible: a physical standby is byte-for-byte identical to the primary, but a logical standby may be very different. Even though it will have been instantiated from a physical standby, it will have diverged: different dbname and dbid, the physical and logical structures will have changed, it may have additional objects, it may have objects that are not maintained.

Hibernate Interview questions

where can i find technical frequently asked interview questions on hibernate. i am new to hibernate and i want to learn about hibernate
can anyone please help me

The purpose of Hibernate is to relieve the developer from a significant amount of common data persistence-related programming tasks. Hibernate adapts to the developer's development process, whether starting from scratch or from a legacy database.
Hibernate not only takes care of the mapping from Java classes to database tables (and from Java data types to SQL data types), but also provides data query and retrieval facilities and can significantly reduce development time otherwise spent with manual data handling in SQL and JDBC. Hibernate generates the SQL calls and relieves the developer from manual result set handling and object conversion, keeping the application portable to all SQL databases.
Hibernate provides transparent persistence for "Plain Old Java Objects"; the only strict requirement for a persistent class is a no-argument constructor, not compulsorily public. (Proper behavior in some applications also requires special attention to the equals() and hashCode() methods.[1])
Hibernate is typically used both in standalone Java applications and in Java EE applications using servlets or EJB session beans.

10gr2 standard edition standby question - archive log shipping

Hello,
I have 2 servers with 10gr2 standard edition, one is production(primary) and secondary is standby on windows platform. To keep standby synchronized i use a script to copy archived logs from primary to standby and applying manually (with scripts).
My question is: can i use redo transport service in order to copy archivelogs from primary to standby ?
Thank you in advance.

Hi,
It is a bit of topic.
According to the Licensing Document page 10 DataGuard is not supported for standard edition.

Ye olde "delete archivelogs in standby" question

11.2.0.2.0
According to note
Configure RMAN to purge archivelogs after applied on standby [ID 728053.1]
oracle should remove archive logs if we have deletion policy set to "delete applied on standby" which I have set on primary and standby. Monitoring the alert log we see
"Deleted Oracle managed file /path/to/an/archive/log"
so we think cool, its removing them automatically. Question is, when does it delete them? Right now my standby is in sync, yet my alert log is only sporadically showing my logs being deleted which were applied hours ago which I can visibly verify.

So I switched the logs a couple of times in production as well to see would that help and we did get some deleted then to bring the space used down to 17.5.gb which is just below the 85% mark.

so what I take from this is that if there is any space available in the 15% free then Oracle waits to be woken up by the receipt of a log from primary, sees that theres less than 15% free and deletes logs to below that limit. however, if the space free is less than the space used then oracle wakes up itself and deletes the logs. Cool.

Router HSRP Active/Standby question

Hello,
Can I use following command to setup HSRP Active/Standby mode for both router ?
Router A:
ip address 10.10.228.202 255.255.255.248
standby 3 ip 10.10.228.201
standby 3 preempt
Router B:
ip address 10.10.228.203 255.255.255.248
standby 3 ip 10.10.228.201
standby 3 preempt
standby 3 track 1 decrement 10
standby 3 track 2 decrement 10
Thanks

Wilson,
we don't know what objects you're tracking, so it's a little bit difficult to answer the question.
You use the default priorities on both routers (100), so, as long as track objects 1 and 2 are up, Router B will be the active router, because it has the higher IP address.
If track object 1 or 2 goes down, Router B's priority will be reduced to 90 (or 80 if both are down at the same time), so Router A will become active, because preemption is enabled.
If the track object(s) change to up, Router B will take over again, because it also has preemtion enabled.
Correction:
Preemption only comes into play when the local priority is higher than the priority of the current active router. In your examle, the priorities on RA and RB have the same values. The IP addresses serve as a tie breaker only in the initial phase, the preemption feature doesn't consider the IP addresses later on.
Consequence: Router A continues beeing the active router.

Rebuild standby question

Good morning,
I am puzzled by this in rebuilding standby process. I remember see this:
Before run “rman dup for standby …” you do “ALTER SYSTEM SET LOG_ARCHIVE_DEST_STATE_2=defer..” in primary db.
After finish RMAN dup and start MRP process you do “ALTER SYSTEM SET LOG_ARCHIVE_DEST_STATE_2=enable..” in primary db.
So during this RMAN dup time period (it can take several hours) we don’t ship any archive logs to standby and when RMAN finishes it inevitably has a lot of logs not in standby side. Does this mean that we definitely are going to have log gap after the RMAN dup? Do we need to manually copy those archive logs from primary to standby in order for MRP to apply them? What is the main reason we disable the log ship during rman dup period?
Thanks a lot in advance for sharing your insight!!
Shirley

The main reason to disable shipping during the dup is nothing exists to apply them to. If you are using RMAN to dup a standby you probably will move the RMAN backup and the current logs over before you issue the dup command which is something like this:
RMAN> run {
allocate channel C1 device type disk;
allocate auxiliary channel C2 device type disk;
duplicate target database for standby nofilenamecheck;
Once you have the new Standby you can "enable" shipping again. I generally do a log switch on the primary and used the v$ view v$archived_log to check the results. v$archived_log will show logs on both primary and standby, use the DEST_ID to check just one side and order by sequence#.
The alert log on both sides are a great source of information.
Does this answer your question?
Thoiught about this more. You could also try:
duplicate target database for standby from active database;
I have never tested this myself.

Ncf flaky/unpredictable when resuming from hibernate/standby onlaptops

I have noticed on my own laptop, and some of my customers are complaining about the same thing... many times when you resume from either hibernate or standby, the client firewall, either does not allow any traffic, or only some of the allowed applications.
It is simply a matter of unloading and reloading ncf to fix this, but the end-users do not like this, and each time they run into it, usually results in a call to the IT staff.
Is this a known bug? Is there any solution for it?
Thanks.

i don't know if novell has acknowledged this as a real bug or not but i
used to see this happen. it was consistent if the IP address changed
when you came out of hibernate... say you're at a hotel and it's using
DHCP to hand out IP#s for high-speed. in the AM, you check your email
and hibernate for the drive to the jobsite. Once there, you
de-hibernate and the jobsite uses DHCP as well. You grab a new IP#
from the DHCP server when the NIC comes back to life and NCF goes off
the deep end. As a consultant, I ran into this alot and wrote a couple
simple BATs to work around it:
to stop:
net stop "novell client firewall service"
PING 1.1.1.1 -n 1 -w 1000 >NUL
to start:
net start "novell client firewall service"
PING 1.1.1.1 -n 1 -w 1000 >NUL
"C:\Program Files\NovellClientFirewall\NCF.EXE" /waitservice
You run the stop right before you hibernate and then the start right
after. The downside was the minimal exposure window. All that said, I
haven't had it happen in maybe 4-5 months so you might want to check
the auto update and see if the clients are running the latest version.
Cheers!

Hibernate license question

Hi,
I am planning to use hibernate which comes under LGPL license perview.
My question is that can i Use hibernate library (without modifying it) for my Java application and then include the hibernate jar in EAR file for deployment purpose?
Regards
Aman

You don't "purchase" LGPL.
LGPL is a legal contract that you must agree to before you can legally use Hibernate. You can read it yourself if you like. As I recall, by agreeing to it you promise certain things, like for example you will not redistribute Hibernate and claim that you wrote it yourself, and so on. As the others said, there is probably nothing in there that would prevent you from taking the Hibernate jar file and using it in whatever way you like.

Satellite A100 Hibernate / Standby wake up problems (doesn't work!)

Hi,
I have a Toshiba A100 Satellite PSAARA-055007 with Win XP Home SP3 and current updates.
For the life of me, I cannot get this machine to successfully wake up from standby or hibernate!
It goes into hibernate and standby just fine, but when you try to power it back up or take it out of hibernate or standby it seems to start waking up and then it just hangs without the display ever powering up. The only option is to hard boot the system.
So at present Standby or Hibernate do not work at all.
Anyone? Please help!

>If it's a windows issue, where should I be looking?
You are using Win XP?
In such case you should check the Toshiba Power Saver tool.
First of all you should reinstall this utility. As far as I know the Toshiba Power Saver controls the hibernation and standby mode
But of course; this could not be related power saver but windows in such case just an new installation might be helpful

Logical standby question

Hello Everyone,
The application team has a request, they want to set up logical standby . But if they delete records from primary, those records should NOT get deleted from logical stdby. Is this possible ?
They want to create a database which acts like a archive of the primary and stores all the data . Insertions should get reflected , but deletion happens in primary , it should not happen in the archive database.
Please give your valuable inputs. Thanks

Swing + JGoodies, EJB3 / Hibernate - Design question...

Hi,
Forgive me if I screw up the terminology here.. I'm pretty new to J2EE and Swing development. I'm developing a Swing based application to replace a paper process. It's basically a long form that gets submitted to a server where it is reviewed and in some cases sent back to the user for corrections. I'm having trouble figuring out a good implementation for the data tier.
The prototype that I've developed makes extensive use of the JGoodies framework (Forms, Binding, Validation). The domain model is basically a bunch of POJO's. For each object there is a separate validator object which has a a validate() method that returns a ValidationResult object. On the Swing side, there is a Model object for each POJO/Validator which listens for changes to the result of validate(). The GUI class attaches to the model and updates the GUI to reflect results of the validation. Basically the result is that if you don't fill out a required field, the field's background color changes and you get a list of reasons why you aren't allowed to submit the form at the bottom of the page. What you type in the field is synchronized with the data object on key release or focus changes (not sure yet).
Pretty much all of this functionality rests upon the domain model calling 'firePropertyChange' in the setXYZ() functions. This solution seems to work when the client uses Hibernate to persist the objects directly to the DB Server, but I'm wondering if/how it could work if we decided to use EJB3 Entity Beans for storing the data instead of Hibernate (primarily because we don't want to leave our DB server's port open on the firewall).
From what I've gathered, under EJB3 the POJO's that I'm currently using on the client side (which call 'firePropertyChange') would end up on the server. I am assuming that the 'firePropertyChange' functionality would be broken. When the client binds to the Entity Bean, the server would cause the creation of a new object with simple getters and setters based on the interface on the server side. I assume that this code would be generated for me automatically and I wouldn't be able to get the 'firePropertyChange' functionality back. In other words, the binding between the GUI and the POJO would be lost, along with the automatic validation.
Is this still possible? Was it ever? Was it possible with EJB2 using the Home objects? Should I just stick with Hibernate and let the clients access the DB server directly? Does anyone have any idea what I'm talking about? The only possibility I could think of was to create another layer of java objects and bind the matching properties between the EJB3 entity bean and the model beans that I already have, but this results in an additional class per form element.
Thanks,
Scott

ScottYou definitely want the app server and the database to be on the same side as the firewall. The EJB app tier will stand between the UI and the database. That way you can do validation and, perhaps more importantly, authentication and authorization.
You don't say whether this is an intranet (clients and servers inside the firewall) or Internet application (clients outside the firewall). If it's the latter, you'll have a very hard time indeed continuing with Swing. If you go with a web-based UI (JSPs and servlets), you eliminate the problem of getting through the firewall, but you take on the added complexity of a web tier, an app tier, and a persistence tier.
Why EJBs? You're using Hibernate and POJOs - good choice. Why not ditch EJBs altogether and go with Spring instead? You can use Spring MVC for your web tier and Bob's your uncle.

Oracle standby question?

The datafile locations between the primary and standby can be different. We can use DB_FILE_NAME_CONVERT and LOG_FILE_NAME_CONVERT to convert the paths.
But does the Oracle software need to be installed in the same path on both nodes? I've tried to look for this information in the dataguard doco but haven't seen it.
Any help is appreciated.
If you can provide a link to oracle documentation, that would be great.
Thanks.

Hi,
From the document "Oracle Data Guard Concepts and Administration 10g Release 2"
"In addition, the standby database can use a different directory structure from the primary database."
