Basic flashback config question
I have an Oracle database (10.2.0.4.0 on Linux) installation that I have inherited. A user deleted some data and I attempted to recover it. There were backups and archive log files in the FRA, but when I queried about flashback status I got:
select flashback_on from v$database;
FLASHBACK_ON
NO
1 row selected (0.06 seconds)With that config set to "no" that means I can not use flashback to recover lost data. It must be set to yes before the failure occurs in order to use flashback to recover afterwards. Do I have that right?

If your retention is not enough big, however you disabled FLASHBACK, you cant get it.
But there is a big procedure, if it is really critical, if your database is running in archivelog mode, Restore database in any test server, recover database before deleting rows, Take an export of the table and import into this database.

Hi,
What does the "input" attribute of the struts-config.xml do?
ThanksCheck out the [url http://struts.apache.org/dtds/struts-config_1_2.dtd]struts-config dtd[ur;]. It documents each of the attributes/tags you can use in the xml file.
input Module-relative path of the action or other resource to
which control should be returned if a validation error is
encountered. Valid only when "name" is specified. Required
if "name" is specified and the input bean returns
validation errors. Optional if "name" is specified and the
input bean does not return validation errors.Simply put, it specifes the jsp page to return control to when validation fails - ie return you to the input screen, display errors and let you correct them.

Basic Server Config question: Restricting user access to files & folders
I am in the process of locating a good Apple Server consultant in south florida, but in the meantime I want to educate myself on what we have.
We now have an XServe in our office, running 10.6 Server. We intend to use it as a File Server, and we want to set it up in such a way that we can specify which individual users have access to each directory.
As a 100% beginner, where would you suggest I start in understanding how do this? Or even, which Help resource I should look at to begin learning. I imagine that our senario is a very simple one. I'd appreciate any help or suggestions from anyone out there.Hi
These for starters:

A few post config questions on new setup
Hi Group,
Just a few post config questions.
First, how can I confirm my controller is in fact associating properly with an NTP server? On a typically cisco product, I could just do a 'show ntp associations' or a 'show ntp status'. I cannot see a way to confirm this on the gui or command line.
Second, on my guest network with web-auth, if one were to choose to not use https for web-auth and instead use unsecure http, would that be possible and if so where in the gui?
Thanks.The third field is from a WLC running v7.4 not v7.2. I usually would install a 3rd party certificate, but what eles you can try is issue this command on from the CLI. It had issues working with certain code versions, but you might as well give it a try.
config network web-auth secureweb disable
Thanks,
Scott

Workshop Weblogic config questions
I'm using Oracle Workshop for WebLogic 10.3 and I'm hoping someone can answer some setup/config questions.
When I double click on the server (WebLogic Server v10.3 at localhost) a window opens with various settings that manage how workshop and weblogic work together.
Under "Startup & Deployment" I have the following turned on:
Launch WebLogic server in Eclipse console
Always start WebLogic Server in debug mode
Ignore project compilation errors when publishing (I have this turned on because of errors in a portal project, the errors aren't inmportant, and don't prevent the project form running)
Run stand-alone web module directly from workspace
So, first question, with these settings I was able to quickly switch to debug mode, with out restarting the server, now the server restarts whenever I turn debugging on. What have I done that has stopped this working correctly? How can I get it to start debugging without a full restart?
next question, what happens if I turn on "Start WebLogic Server in Express Mode"? As far as I can tell nothing happens.
Lastly, under "Automatic Publishing" I have it set to "Never publish automatically", if I choose another setting workshop essentially freezes because it's constantly publishing. So whenever I make a change, even in a jsp, I need to remove the project, then re-add it to see my changes in the browser. This is frustrating, not just because it takes 8 or 9 minutes (8 or 9 MINUTES!!!), but because the project doesn't run properly until it is redeployed. You'd think that if it needs to be re-deployed, then none of my changes should matter on the server until it is re-deployed.
So, my question is, Is there any way to get this re-deployment to happen faster?
Thanks for any and all helpWell, in my experience performance is not bad as you experienced. Is it locally connected server or remotely connected server? If it is a remote server, network issue could cause this latency issue.
Is performance better if you run the server without enabling debug mode? If yes, probably you can also review any break points set.
You could also try out the following options
1) Run workshop with -clean option, by opening command prompt and navigating to workshop_home\'workshop.exe -clean'
2) Untick the option 'Launch WebLogic server in Eclipse console' and start server which would enable server to start on command prompt
3) This would enable you to take multiple thread dumps (cutl +Break) on the server console output, while performance is very bad, to see where threads are halt. -
Re: PLM4P v6003 Config Question: Any way to configure UGM Notifications?
After reading:
PLM4P v6003 Config Question: Any way to configure UGM Notifications?
This is one of the requirements from me as well. We always wanted to customize emails sent not only for UGM but also for other modules. We wanted to conveysome message to approvers. But it seems this is still not possible. Is this functionality on road-map of AgielP4P product management?Currently, the subject and body of emails can be customized to an extent, as they are translations that can be overridden. The translations have some placeholder fields that get populated by the system, but you are limited to those placeholder fields. The upcoming release will give you full control of the email body and subject lines, for GSM and SCRM emails, as well as Supplier Rep emails.

Redundant FWSM Config Question
Hello All,
I'm going to be configuring failover with FWSMs for our 6500 at my job and I have a config question. There is one current 6500 chassis with 2 FWSMs installed. They are both online but currently since failover isn't setup, only one FWSM is actually active. My question is since we are using mutiple contexts where do I setup the failover interface, and do I need to configure failover on every single vlan on the FWSM? We have over 10 contexts each with 2-3 interfaces on them, so do I need a failover IP for every vlan that exists on every context? Also, does the failover config get setup on the admin or system context? Any help would be greatly appreciated, and thank you so much in advance!Hi John.
Failover config goes in the system context. For the data interfaces in each context, you will need a primary and a standby IP i.e. 2 IP's per VLAN. Once failover happens, the secondary FWSM will assume the active role and the secondary FWSM will take over the Primary IP address thus making the failover process transparent to end users.
HTH.

Basic recording/feedback question
I'm recording basic vocals against accompaniment tracks using an APOGEE ONE and Audio-Technica 40 series AT8449 condenser mic. I use only headphones, no external speakers.
If I record with "monitoring" on I constantly battle feedback/distortion, especially on songs with a wide dynamic range. When the feedback protection kicks in the message indicates that I'm getting feedback through my external speakers (which I don't have), I can minimize the problem by turning "monitoring" off but I lose the reference vocal. I know I must be overlooking something very simple. Any help is appreciated.hi all,Hi Neerav

Okay, I know this is a basic question, and I'm not sure if this is really where I should be posting it, but maybe someone out there has experience with this.
I have a PDF form sitting on a secure server. I have it set up to email the completed PDF back to our company when the user clicks the SUBMIT buttton. Whether or not the PDF is secure coming back to us would be dependent on the email server the user uses - not that the form sits in a secure area on our server or that the PDF is security settings are set, correct?
Any input appreciated.
Thanks

basic wifi service question
A Windows-using friend of mine subscribes to a service from Verizon that is sort of like a cell phone for a computer - wifi service that you can access from theoretically anywhere, for something like $60 a month -
as far as I can determine, one CAN get this for Mac but ONLY if you have a 15 or 17 inch laptop with PC slots - unless I am missing something. It requires a special kyocera card.
Another company, T-Mobile, offers a similar service, but with no MAC access at all.
So my question is: is there a similar service, wi-fi access theoretically anywhere (or even just anywhere in New York City) ? Hopefully with just the regular mac airport card and not any additional special hardware?
Thanks!
WillHello WillFriedwald2
The kind of service your describing is probably a 3G and GPRS service.
Phone companies now offer mobile high speed connections using EDGE technology or GPRS2 and supply a 3G or GPRS PCMCIA card.
However some companies are now offering a package whereby you get high speed 3g and gprs and also wifi.
So to use this service on a laptop that has no PC card slot you need to get a 3G or GPRS2 phone that supports blue tooth then you can connect your laptop to the phone over bluetooth and therefore access high speed internet.
But if you had a desktop mac such as a G5 you would be better just getting a regular cable or dsl connection in your home and invest in a wireless router. -
Basic JDBC transactional question
Hello all,
I have (what I believe) is a basic transactional JDBC question.
Here's what I want to do:
begin transaction
select a row from a table where (some condition).
that row may or may not exist.
if the row exists: update the row
else if the row does not exist, insert a new row
end transaction
I want this entire thing to be atomic .. I don't want the select to complete, then have something else come in there before the update/insert takes place.
I'm using MySQL .. I seem to remember hearing about some proprietary MySQL command which would do a SELECT + UPDATE atomically .. which would be fine, but I can't find it.
Wrapping this with a row-level lock would be fine too .. I'm just not sure how to do that in JDBC.
Thanks!
-dBy thte way, and not that it helps the orignal poster, who's using MySQL, but Oracle has a proprietary MERGE statement that does "insert or update" in one go. For example:
MERGE INTO bonuses D
USING (SELECT employee_id, salary, department_id FROM employees
WHERE department_id = 80) S
ON (D.employee_id = S.employee_id)
WHEN MATCHED THEN UPDATE SET D.bonus = D.bonus + S.salary*.01
DELETE WHERE (S.salary > 8000)
WHEN NOT MATCHED THEN INSERT (D.employee_id, D.bonus)
VALUES (S.employee_id, S.salary*0.1)
WHERE (S.salary <= 8000); -

SCCM 2012 application portal: config questions
Hi,
We have setup SCCM 2012 application portal correctly and it's working fine.
However some config questions:
-can we change the name of the configuration portal? Now its servername/CMApplicationCatalog ... what's not userfriendly.
We'd like it to be applicationportal.ourcompany.com. Howto achieve that?
-can we customize layout in a supported way (we could change html pages but after an upgrade of SCCM they would/could be erased)?
-how does flexera (adminstudio?) plugs in into this. I've read this entry
http://helpnet.installshield.com/appportal2014/Content/helplibrary/AP_CreatingCatItemSCCM.htm but what's the big picture here? Anybody using this? What are the advantages?
J.
Jan HoedtWe want to offer software center for overview of mandatory installs, application catalog for optional software.
On our companies portal, we can then set a link which directs to the application portal. User can then install optional software from there.
My current config works http://applicationportal.ourcompany.com/ goes to the sccm-server but not to the url below.
That would be http://applicationportal.ourcompany.com/CMApplicationCatalog/#/SoftwareLibrary/AppListPageView.xaml
how can I make sure the application portal shows up when this link is opened?
It sounds like you want to perform a URL rewrite?
http://www.iis.net/learn/extensions/url-rewrite-module/creating-rewrite-rules-for-the-url-rewrite-module
You should test this to see if it's what you want - I may have misunderstood your question.
Also, I wouldn't host this module on your AppCatalog server, I'd host the rewrite module elsewhere.

Basic internet config for t1 incoming wan
what would be a basic internet config on a t1 wic w/ a public ip and two fast ethernet ports? 1841 router. i'm trying to write up a checklist of everthing the config should accommodate so i don't leave anything out.
hello johnny,
sample config of a T1 is as below:
Interface serial 0/0
service-module t1 clock source internal
service-module t1 timeslots 1-24 speed 64
service-module t1 framing esf
service-module t1 linecode b8zs
ip address 10.1.1.1 255.255.255.0
encapsulation ppp
fair-que
no shut
make sure the framing and linecode are configured right. check this with the ISP... if your LAN is on a private range, you also might need to do a NAT/PAT over the T1 interface.. for NAT examples refer to the CCO. you also need a default route to the outside towards the t1 interface...
Hope this helps.. all the best. rate replies if found useful..
