How to alow system with Static IP E2000

I have one system running as a fale server in my house, upgraded my wrt54g to an e2000 and that server cannot get through therouter. if I switch to dhcp it works fine, then switch bake to a static ip outside the dhcp range and use the same mask, gateway, nds,etc I can ping the router but can't get through it. If I then reboot the router it will work for a short time but eventually stop and I have to reboot the router again. I haven't setup any kind of restrictions or other security, server is wired not wireless.

Does this happen with all the computers or only with the server?
Try to assign a static IP address to any other system and see if you can access the Internet on that computer.
What DNS numbers do you use?
You can ping the router when you are not able to access the Internet. Open the setup page of the router and check the Internet IP address on the status page of the router.
How many wired and wireless computers/devices do you have in the network?
Can you access the Internet on any other computer when you are not able to access the Internet on the server?

How To Create Table with Static Data

JDEV 10.1.3
ADF BC
ADF Faces
I am trying to make some simple screen/screenflow diagrams to help flesh out some requirements. To do that, I need to make a table with static data that is not hooked up to a data source (because the data model has not yet been clearly defined, and I'm using the diagrams to help iterate the requirements).
Is it possible to create a table that shows static data (i.e. a set of rows that does not come from a model data source, but rather is hardcoded.)
If not, how does one create mock ups without actually implementing the data model?
Thank you.

Deepak, what specifically in those 2 links from Amis are useful? Those 2 posts are about bind variables, not static list of values?
In response to the original poster, I'll attempt to help a little more.
In the 11g release you can create VOs based on a static list of values. However in your case on 10.1.3, the best method I've found is to create a VO based on a SELECT <columns> FROM DUAL statement. The columns then include your dummy data. If you need more than one row, simply UNION ALL a number of SELECT statements together.
What I haven't checked, is when you eventually transform the VO based on the SELECT DUAL statement into a VO based on an EO drawing real data from the database, is it an easy process? I recommend you try this out before committing to the approach above. Let us know how you go.

CM.

How to import files with static variables into a block with methods?

i have a problem. is it possible to import files with static variables into tags like
<%!
//here i want to import a file named settings.inc
//whitch is used to set jdbc constants like url,driver,...
private void method() {
private void method2() {
%>
<%@include file="xy"%>//dosn�t work above
//only in <%%>tag

This should be done using either the Properties class or ResourceBundle. Ex.
<%
ResourceBundle resBun = ResourceBundle.getBundle(String resource);
String username = resBun.getString("username");
String password = resBun.getString("password");
// etc
%>

How to configure router with static IP

Hi,
I have requested a static IP from ISP provider.
Now I would like to give static IP addresses to all my internal PC's using my Mac Extreme router.
my ISP requires the Airport extreme to be configured in 'DHCP' (internet connection).
If I use 'static' then the ISP router does not see my Extreme router.
However my mac router does not allow me to use internet connection 'DHCP' when using router mode 'DHCP only'
Can anybody give me a some tips?
Thanks in advance

You are talking about two completely different Static IP questions here.
If your ISP has issued a Static IP address to you for the AirPort Extreme, this is the IP Address that you must use in order for your AirPort Extreme to connect to the Internet.
Open AirPort Utility, click on the AirPort Extreme icon and then click Edit
Then click on the Internet tab a the top of the screen.
The setting for Connect Using must be set to Static, and you will need to enter in the IP address, DNS servers, etc information that your ISP has provided for you to be able to connect to the Internet. In the screenshot example below, you would enter the Static IP address that your ISP provided to you in the IPv4 box.
For now, click the Network tab at the top of the screen and insure that the setting for Router Mode is set to DHCP and NAT.
We first need to make sure that your AirPort Extreme can connect to the Internet using the Static IP address that you have been assigned.
Then, we will tell you how to set up Static or Reserved IP addressed for each of your devices on your local network if this is what you want to do. Normally, this would not be needed, but it can be done if you wish.

How to play Mozaic over car radio speaker system without static?

Playing Zen Mozaic over Car?s Radio Speaker system without static?
I just purchased a Zen Mozaic and want to use it primarily for playing books downloaded from the local library over our car?s radio speaker system without static.
I purchased a cheap audio cable to connect the zen to the AUX interface in the car but I understand that trying to play it over the car runs into the problem of bad static.
Is there some device that will allow me to play the Mozaic over the car radio system without static?
Thanks very much.
Bruce? [email protected]

D? Are you simply plugging a jack from the headphone output on the Zen into a headphone-like input on your stereo? That sould work fine, with possibly only slight "whine". If you are wiring into the back of your stereo, it should work just as well unless you have poorly shielded cables or your car has crummy sparkplugs. Do a Google search on this---what you are doing in case 2 is common on motorcycles and they will tell you how to use a resistor circuit to cut down on ignition interference.
You can also either use a cassette adapter (if your stereo has a cassette player) or an FM transmitter (many varieties of these). The FM transmitter works well, but you'll pick up static and interference if you dri've into an area where an actual FM station is using that frequency. You just have to "change channels" on your radio and transmitter in this case---simple. The sound is pretty good (not as good as direct cable or cassette adapter) and is more than adequate for books.

Solstice DiskSuite[TM] Software: How to Delete and Reset a Lost Root Password on a System With a Mirrored Root Disk [ID 1010755.1]
Solution
Steps to Follow
How to delete and reset a lost root password on a system with a mirrored root disk.
1) Insert the Solaris[TM] Operating System CD-ROM into the CD-ROM drive.
2) Once the CD-ROM is in the drive, perform a stop-a. This brings the system down to the "ok" prompt.
3) From the "ok" prompt, perform a single-user boot from the Solaris OS CD-ROM.
ok boot cdrom -s4) At the "#" prompt, determine which disk is the system's boot disk (containing the root file system). There are several Oracle architectures and various configurations of systems when it concerns a boot disk. As a general rule, most boot disks are attached to controller 0 (c0). Usually, their SCSI target is
either 3 (t3) or 0 (t0). However, Oracle machines are very flexible, and the boot disk could be at a different location. If you are not sure which disk is your boot disk, perform the following steps to determine the location of the boot device:
a) # eeprom boot-device
The output might appear to be simple, such as "disk" or "disk1" or more complicated, such as a pathname "/iommu/sbus/espdma@4,8400000/...../sd@3,0:a".
b) Make note of the boot-device. If the boot-device is a pathname, it is beyond the scope of this information to provide the location of the customized boot disk. However, for most configurations,
finding the customized boot disk is an easy task. The "Format" command shows all available disks:
#format
Searching for disks...done
AVAILABLE DISK SELECTIONS:
(enter its number): c) Enter d to exit format.
Now, you will have an idea what disks are on the system. Therefore, if the boot-device is "disk" and format shows "c0t0d0" (on some systems "c0t3d0") then that is the boot device. If boot-device
shows "disk1" and format shows "c0t1d0," then that is the boot device. If format shows multiple disks, then based on what the "eeprom boot-device" command shows, the system's boot disk would be:
boot-device format
disk c0t0d0 or c0t3d0 (machine dependent)
disk1 c1t0d0
disk2 c0t2d0
disk3 c0t3d0 or c0t0d0 (machine dependent)
and so on ....
5) Because the system was not brought down gracefully (no root password means having to use the Stop-a keystroke to "crash" the system), you need to run "fsck" to clean the root partition (slice). The fsckalso confirms that you selected the proper slice.
# fsck /dev/rdsk/c1t0d0s0
where the X and Y are determined by the previous procedure. It is also possible to have a root partition which is not on slice 0 (s0), but, again, that is not a standard configuration.
The output of "fsck" looks like this:
** /dev/rdsk/c1t0d0s0
** last mounted on /
** Phase 1 .....
The second line in the output of "fsck" ("** Last mounted on /") confirms that this is the correct root filesystem partition. Answer "y" to any questions fsck asks. There shouldn't be too many items
needing repair. If there are, there is a possibility of a corrupted root filesystem. After fsck is finished, mount the root partition:
# mount /dev/dsk/c1t0d0s0 /a
Again, X and Y are the same as for the fsck command.
For example:
# mount /dev/dsk/c1t0d0s0 /a
6) From the root prompt, set the proper TERM type command (such as vt100, dtterm, sun, and so on)
by entering this command:
# TERM=sun; export TERM
7) Use the VI text editor to edit the /etc/shadow file:
# vi /a/etc/shadow
8) The first line of the /etc/shadow file is the one you want to modify.
It looks like this:
root:c3.yAVmYodWsc:6445::::::
9) Delete every character between the first and second colons in the first line of the file. When you finish deleting the characters, the line should look like this:
root::6445::::::
10) Press the Escape key, then enter the following to save the file and exit vi:
:wq!
11) Use the VI text editor to edit the /etc/system file andremove the "rootdev" line shown below:
# vi /a/etc/system
*rootdev:/pseudo/md@0:0,0,blk
Don't comment out the "rootdev" line. Actually remove it.
12) In the /a/etc/vfstab file, replace the lines for the system filesystem meta-devices with their underlying partitions. For example, change lines from
/dev/md/dsk/d0 /dev/md/rdsk/d0 / ufs 1 no -
to
/dev/dsk/c1t0d0s0 /dev/rdsk/c1t0d0s0 / ufs 1 no -
ONLY change the lines for root (/) and the filesystems that were affected by the actions you took in step 1 of this procedure. All other metadevices may stay as is in this file.
13) Unmount root, check the root filesystem, and then stop the system:
# cd /
# umount /a
# fsck /dev/rdsk/c1t0d0s0
# stop-a
14) Boot to single-user mode:
ok boot -swTHIS STEP IS VERY IMPORTANT; YOU MUST BOOT TO SINGLE-USER MODE TO AVOID FILESYSTEM CORRUPTION.
If the system does not boot to single user mode, you might have made a mistake in the previous steps.
15) Because the root password was cleared in an earlier step, press Return when prompted for the the root password. Once you are in single-user mode, you must clear the metamirrors and all the sub-mirrors for the root filesystem. For example, if root (/) is d0, run the following command:
# metaclear -f -r d0
Running the metaclear command not only clears the metamirror but also clears the submirrors that are part of this mirror.
16) When the metamirror is cleared, continue the boot up to multiuser mode by either pressing CTRL-D or by entering the following:
# exit
Now everything should be as it was, except that the system partition is on the underlying partition and isn't mirrored. You will simply need to re-create the metadevices for the root mirror as you had originally.
many thanks

Hi,
Halt your machine.
Boot with fail-safe mode.
format and list out the disks. (You can get the root & mirror disk (c#t#d#) details from /etc/lvm/md.tab of your root or mirror disk. Earlier explorer output may help)
Mount the root disk and remove the password entry in /etc/shadow
umount it.
Mount the mirror disk and remove the password entry in /etc/shadow
umount it.
reboot the server.
Hope this helps!

How to connect SAP R/3- System with SAP NetWeaver Portal (2004s)?

Hello to all,
sorry, can someone help me? How can I connect SAP R/3- System with SAP NetWeaver Portal (2004s)?
Thanks and regards,
Galyna

Hi,
In previous link contain this info
This describes how to connect an SAP R/3 system to SAP NetWeaver Portal using an iView
1)      Go to System Administration
2)      Go to System Configuration
3)      Go to Portal Content (Right Side Panel), open that folder.
4)      Right Click on Portal Content, a Panel is displayed select "System (from Template)".
5)      That will display a new view on right side, now select "SAP system using dedicated application server" from
the existing templates. (Other templates are possible - for example, load balanced or through a SAProuter connection string).
For this exercise, we'll use the simplest type.
6)      Choose next
7)      Give the System Name and System Id (which are mandatory fields) incase you want to give any brief notes
about the system then give them in the "Description" field.
8)      Open the Newly Created System.
9)      Now when you want to create a New System, you have to fill four Properties they are:
"Connector" - contains basic connectivty details
"Internet transaction Server (ITS) - if you wish to use SAPGUI for HTML and/or IACs",
"Web Application Server" - if you wish to access BSPs and/or Web Dynpro for ABAP and
"User Management".
You also need at least one "System Alias" has to be defined from the Display drop down menu.
Make sure you have set end user access in the Permissions drop down menu to all users who need to access the system
10) Select "Connector" property, now fill the required fields such as:
a)      Application Host (should be fully qualified hostname) - Give the R/3 "Application Name",
which can be obtained from the SAP Logon Pad (check what R/3 system you are using, right click on it , go to the properties,
it will open a window which has the Application Server Name.
b)      Logical System Name - Give the logical name as defined in the backend system
c)      SAP Client - Check the Client in the backend system and give the appropriate number (3 digits)
d)      SAP System ID(SID)* - Check the R/3 properties and give the check for System ID
e)      System Type* - Since we are connecting to R/3, select SAP_R3 system.
f)       System Number - This is a two digit number that you can find in the SAP Logon Pad
11) Select "Internet transaction Server (ITS)" property, now fill the required fields like
a)      ITS Description à Give some Description
b)      ITS Host Name - Same as "Application Host" of R/3 (when integrated ITS) and should be attached with the
port number of ITS Server (to get port number detailed description is given below). ex: hostname : port number
c)      ITS Path - To get the path along with the port number you have to Log on to R/3 system. Use the
Transaction Code "SICF", it opens a new window go to:
      default_host -> sap -> bc -> gui -> sap -> its -> webgui -> SAP GUI for HTML -> right click on
that and click "Test Service'. This will open a new window, on the address bar you will find the "port number", and
the path something like (/sap/bc/gui/sap/its/webgui). Use the path after the port number.
d)      ITS Protocol - There are two protocols "http" & "https", select the appropriate protocol which is
visible when you opened "Test Service" window.
12) Select "Web Application Server" property , now fill the required fields like
a)      Web AS Description -> Give some Description
b)      Web AS Host Name - same as ITS Host Name
c)      Web AS Path - usually /sap/bc/bsp/sapd)*
Web AS Protocol - should be same as the ITS Protocol.
13)   Select "User Management" property, now fill the required fields like
a)      Authentication Ticket Type - Since we are not using SSO leave the field
empty i.e. put in select mode. (Please note that longer term you will probably want to use SSO)
b)      Logon Method - Select UIDPW.
c)      User Mapping Type - In case you have administration rights then you choose "admin" or in case you
just have user rights then choose "user", better go for "admin/user".
14)   Since all the required fields are filled appropriately now create a System Alias name, this can be done by following steps:
a) go to Display -> Select "System Aliases" give some Alias Name, let's call it "SAP_R/3"
15) Now that System is created we have to create a iView which will display the given Transaction Code.
16) Go To "Content Administration".
17) Go To "Portal Content".
18) Go to Portal Content (Right Side Panel), open that folder
19) Right Click on Portal Content, a Panel is displayed select "New" -> iView
20) Select iView template, click next
21) Select "SAP Transaction iView" from the list of templates available. Click next.
22) Give the iView name and iView ID. Incase you want to give any brief notes about the iView then give it in "Description" field. Click next
23)   Select "SAP GUI for HTML" radio button. Click next
24) Now select the system which you have create "SAP_R/3", give some Transaction Code, say SE12 (Dictionary Display). Click next and Finish.
25) Now Preview the iView
26) You will see a new Window where in SE12 Dictionary Display window is displayed.

How to cooperate the current mail system with Sun Java Commnication Suite 5

Dear all and Shane,
Excuse me for bothering you again.
Due to time limited, I would like to know how to cooperate the current mail system with Sun Java Commnication Suite 5. I mean I would like to use current mail system (mailscanner + postfix + courier-IMAP + clamav + spamassassin + webmail) and use the outlook connector to connect to Sun Java COMMS 5 to share the calendar, contacts only.
Right now I have done the testing by using outlook, mac mail, thunderbird to share calendar,contacts via Sun Java COMMS 5 in Centos Linux 5.
My plan is as following
1. Sun Java Communication suites 5 server ( I called it comms5 ) will be in DMZ zone and will open the necessary ports in firewall.
2. I will create more than six sub domain name in Sun Delegate server and the necessary accounts within these domain names.
3. All messages will be transmitted via Postfix and clients will retrieve from Courier-IMAP
4. All Clients included other branch offices will use different mail clients to share their calendars, contacts via COMMS5 ( But how will COMMS handle the messages such like invitation ? )
Any suggestions will appreciate.
PS: Is it possible to classify the contacts in outlook address book ?
For example, when user click the receiver, it will show like as following
GLOBAL ADDRESS BOOK
--Director
--and so on
----CN.BRANCH OFFICE
-----------CN01 EMAIL ADDRESS
-----------CN02 EMAIL ADDRESS
-----------CN03 EMAIL ADDRESS
and so on
----JP.BRANCH OFFICE
-----------JP01 EMAIL ADDRESS
-----------JP02 EMAIL ADDRESS
-----------JP03 EMAIL ADDRESS
and so on
----TW.BRANCH OFFICE
and Due to the user account is located in CN.BRANCH OFFICE, it will extend the CN.BRANCH OFFICE contacts level.
Excuse me for bad English, hope you can understand it.
Best Regards,
Bruce

Also the use of Outlook Connector with a non-Sun IMAP backend isn't supported, nor is the use of a non-Sun IMAP backend possible with UWC.
Right now I have done the testing by using outlook, mac mail, thunderbird to share calendar,contacts via Sun Java COMMS 5 in Centos Linux 5. Once again I should remind you that CentOS is not a supported platform for comm-suite-5

How to configure R/3 System with Load Balancing?

Hello,
I've created a Web DynPro Application and I would like to case an iView on it. According to SAP tutorials I first need to configure an R/3 System with Load Balancing.
My problem is how to configure the "WAS Host Name".
According to the tutorial:
WAS Host Name = <host>.<domain>:port (this corresponds to the Web Dynpro server location and the port on which it is running eg. PXYZ.wdf.sap.corp:50000.)
I am using NW 04 and my portal is running on this address:
http://ep6sp9test:50000/irj/portal
When I set the WAS Host Name to ep6sp9test:50000 the Test connection fails (I have privildges and created an alias and User mapping). What should I put at this field then?

Hi
I think you have to specify the HTTP port og the WAS running the R/3 system. The 50000 port is the HTTP port of your portal - not the R/3 system. You can see the HTTP port of the R/3 system using transactioncode SMICM - services in the R/3 system.

CUA with HR-Org - How to assign systems for role

Dear all,
we are planning to use CUA with HR-Org assignment. Can please anyone explain to me how or where the system for the role comes from.
I mean, normaly in SU01 -> Role Assignment I have in the first colum the system and in the second colum the role. It the role assigment come from HR-ORG there is always the local logical system in the system colum. This is not what we want.
CUA is on Solution Manager, HR-ORG is replicated from R/3 HR Systeme and the user needs the roles in ECC production systeme.
So how can we manage the system/role combination assignment?
Thanks for any hints.
Best regards
Roman

Hi,
If I understand your problem you want to do role assignment from the HR-Org structure on a system that is using CUA.
I have only managed this successfully when the CUA master is also the system with the HR-Org structure on it. Otherwise you have lots of issues with replicating data between systems. I did this for a UK council's SAP solution where we allocated all the roles from the HR system, including roles on ECC, SRM(EBP), CRM and BI - so it does work.
PO13 on the system with the org. structure will only allow you to allocate a role that exists on that system, but if the roles that you are allocating are composite roles that include single roles on other systems, you can achieve this sort of business role allocation without having to go the IdM route.
Darren Hague (no relation) gave a presentation at SAP Tech Ed 07 on such a scenario, that explains how the composites would be set up far better than I can, but in essence you use the CUA connectivity and the rights of the CUA master system (which includes the org. structure) to allocate roles on other systems / clients in your CUA landscape.
Have a search through SAP Tech Ed 07 presentations and you should find what you are looking for.

Hi Dharani,
You can get information from the following links:

SAP CONNECTORS:- Basically Connectors are like middlewares , that we use to connect to the backend system including Non SAP systems also. Will try to explain it to u with some examples of SAP Connectors:-
a) SAP Business Connectors:-
A middleware application based on the B2B integration server from webMethods.
The SAP Business Connector enables both bi-directional synchronous communication and asynchronous communication between SAP applications and SAP and non-SAP applications.
The SAP Business Connector makes all SAP functions that are available via BAPIs or IDocs accessible to business partners over the Internet as an XML-based service.
The SAP Business Connector uses the Internet as a communication platform and XML or HTML as the data format. It integrates non-SAP products by using an open, non-proprietary technology.
b) SAP Java Connector:-
SAP Java Connector (SAP JCo) is a middleware component that enables the development of SAP-compatible components and applications in Java. SAP JCo supports communication with the SAP Server in both directions: inbound calls (Java calls ABAP) and outbound calls (ABAP calls Java).
SAP JCo can be implemented with Desktop applications and with Web server applications.
SAP JCo is used as an integrated component in the following applications:
1) SAP Business Connector, for communication with external Java applications
2) SAP Web Application Server, for connecting the integrated J2EE server with the ABAP environment.
SAP JCo can also be implemented as a standalone component, for example to establish communication with the SAP system for individual online (web) applications.
To Know more go through,
SAP Java Connectors
II) ALE Concept:-
ALE is not restricted to communication between SAP systems, it can also be used for connecting SAP Systems to non-SAP systems.
By using IDocs as universal information containers, ALE can reduce the number of different application interfaces to one single interface that can either send IDocs from an SAP system or receive IDocs in an SAP system.
SAP certified Translator Programs can convert IDoc structures into customer-defined structures.
Alternatively, the RFC interface for sending and receiving IDocs can be used in non-SAP systems.
In both cases you need the RFC Library of the RFC Software Development Kit (RFC-SDK).

III) Communication Between SAP Systems and External (Non-SAP) Systems using RFC:-
When you use RFC for communication with an external (non-SAP) system, you can also implement the SAP Java Connector or the SAP .Net Connector for the conversion of data. However, there are no specific security requirements for these components, since they only perform internal system conversion functions.
The additional security recommendations for communication with external systems in this section make particular reference to cases where an external system is used as a server (SAP calls the external system). If you use an external system as a client (the external system calls SAP), the appropriate SAP-specific security mechanisms are implemented on the SAP side.
This link explains in detail all the security considerations you need to take for connecting to an External Non SAP system like, User administration, Network Security etc.
