WebCache connection error (WWC-40019)

Dear All,
I installed Oracle9iAS Release 2 Portal & Wireless installation type on my PC and the Oracle Infrastructure on another PC. When i tried to follow the described steps to shutdown my Oracle9iAS instance and then the Infrastructure instance to increace the RAM size of the Infrastructre machine and when i tried to startup the infrastructure and then my portal instance. I faced with the problem that my portal instance can't connect to the web cache and got the following error message :
Error: Could not open web cache connection. The portal use-web-cache setting is set to ON while web cache
may be down. (WWC-40019)
Any help will be appreciated.

Web Cache Connection Error

Hi All,
I had installed Application Server 10g on one Window 2000 Server machine. It was working fine. But as all the components of Application Server were installed on one machine thats why its performance was bad.
So i decided to move the Oracle AS Portal to another machine. I installed only oracle portal and its required subcomponets on another machine. The new instance used the old server's metadata and other services.
The Portal Now works fine but there are certain issues.
First is that when i deploy an application on the new portal home and when try to register it, it gives me following error:
=============================================================
Internal error (WWC-00006)
The provider URL specified may be wrong or the provider is not running. (WWC-43176)
=============================================================
The Provider URL is also correct and the the provider is also running. as when i open the URL in browser it gives me success page.
The Second Error is of Web Cache. and i think it could be the cause of the first error as well.
When i go to the global Setting of the Portal/Administer, and then to Cache Tab and check Clear The Entire Web Cache and press apply i get the following error.
=============================================================
Could not open web cache connection. (WWC-40019)
=============================================================
I checked everything and everything seams to be fine. Remember that now the WebCache is pointing to the new server webcache services.
I need help in removal of these problems.

Hi Osama,
See my reply in the Install forum:
Just checking, have you reviewed the OracleAS Portal Error Messages Guide for the error message "WWC-40019: Could not open web cache connection?"
This guide can be found on OTN at http://www.oracle.com/technology/documentation/appserver1012.html and it t describes this error and what can be done to solve it in detail.

This error could happen because of various causes. These are mentioned in the Config Guide.
Oracle9iAS Portal Configuration Guide Release 2 (9.0.2)
8.1 Oracle9iAS Web Cache related issues
Error: Could not open web cache connection. The portal use-web-cache setting is set to "on" while web cache may be down. (WWC-40019)
http://portalcenter.oracle.com/pls/ops/docs/FOLDER/COMMUNITY/CONFIGHTML/cgtroub.htm#1015385
Most often the reason is that of wrong Web Cache related config. info.in the Portal.
The following doc on scripts might help you address the config. issue
B.2 Oracle9iAS Web Cache configuration scripts
http://portalcenter.oracle.com/pls/ops/docs/FOLDER/COMMUNITY/CONFIGHTML/cgscript.htm#639250
If your problem is still not sovled you might want to read the following sections

Have you tried to register your provider with other then english logged in user?
If yes, plesase log out, and log in to english language Portal, and register your provider!
I don't no if this Portal bug still exists in 10.1.2.0.2 (Build: 139).

Hi,
Firstly, would you please post the result of running “ipconfig/all” on the DHCP server and domain controller?
It seems that the DHCP server cannot be authorized in AD DS. Please make sure that the DHCP server is a domain member and try to ping the domain controller on the DHCP server.

Data Federator data source not available causes Universe Connection error

I created a Data Federator project that connects to 20 servers across US and Canada. All data sources are SQL Server 2005. The DF project maps 40 source objects into 4 target objects. I created a universe based on the DF project and we have been quite pleased with Webi query response. Today one of the source servers was taken off line and this generated a connection error when trying to access the universe (not trying to access the data source that failed). We do not want the universe connection to error when one source server is not available u2013 is that possible?
If the answer is no then I see us abandoning what appears to be a great solution for real time distributed reporting and resorting to ETL and moving data.

Hi Chapman,
Can you be little elobrate on what you have done to solve the issue.

RFC connection error between Netweaver 7 EHP1 and Ides ECC6

Hi Friends,
I try to create source system in BI from Netwever EHP1 to IDES ECC6 EHP3.
During the creation I get a connection error, says. check connction parameter.
I checked the parameter, everything is fine. Server, System and number.
When I went to the SM59 and created a connction.
I.E. with the same parameter like system = 06 and server = compi9 gave client 800 etc.
The Host name is resolved to 192.168.2.111 wich is OK.
But when I run the connection test it shows me "ERROR: partner '80.156.86.78:sapgw06' not reached"
I have no idea where this IP '80.156.86.78" is comming from.
No Problem with the opposite way, from Ides to NW and login to the System is OK too.
Can anybody help me with this problem.
RG. Jimbob

Hi,
What is the next screen that comes up when you click on remote logon.
If no screen comes up then:
Check the user type of the user id used for this RFC.
It should be either dialog or service user for able to remote login.
If it open a new window and asks for password, then its excatly password issue.
Also make sure that the password is in numeric and correct.
Also make sure that the current user check box is unchecked.
Even if it dosent work, delete the connection and create again.
Please award points if helps.
Thanks
Santhosh

Hi,
Please follow this steps:
Creating RFC Destinations in the ABAP and Java Environment
You need to create the following RFC destinations in transaction SM59 (ABAP) and the Visual Administrator (Java):
u2022 AI_RUNTIME_JCOSERVER
u2022 AI_DIRECTORY_JCOSERVER
u2022 LCRSAPRFC
u2022 SAPSLDAPI
Depending on your client settings, it may be necessary to be logged on your SAP Exchange Infrastructure host as SAP system user with the authorization to maintain customizing tables and to release transport orders. Note, that user "SAP*" or "DDIC" does not have these authorizations.
Maintaining the RFC Connections (Transaction SM59)
1. Log on to your SAP Exchange Infrastructure central instance host.
2. Call transaction SM59.
3. Choose Create.
4. Enter at least the following:
RFC destination: AI_RUNTIME_JCOSERVER
Connection type: T
Description: <your description>
5. Choose ENTER
6. Choose the tab Technical settings and do the following:
a. Select Registered Server Program
b. In the Program ID field, enter: AI_RUNTIME_<SID> where <SID> is the SAP system ID of your Integration Server host. Use uppercase letters only.
c. Enter Gateway host and Gateway service of your Integration Server host. To find out the required parameters:
a. On the Integration Server host, call transaction SMGW
b. Choose Goto u2192 Parameters u2192 Display (see entries for gateway hostname and gateway service)
7. Choose tab Special Options and select the flag Unicode in the box Character Width in Target System.
8. Save your settings.
9. Repeat the steps 3 u2013 8 for the remaining destinations:
Destination
Values
AI_DIRECTORY_JCOSERVER
Program ID: AI_DIRECTORY_<SID>, where <SID> is the SAP system ID of your SAP XI host
LCRSAPRFC
Program ID: LCRSAPRFC_<SID>, where <SID> is the SAP system ID of your SAP XI host.
SAPSLDAPI
Program ID: SAPSLDAPI_<SID>, where <SID> is the SAP system ID of your SAP XI host.
10. Leave the transaction SM59 open for later tests.
J2EE Configuration for the Destinations (Visual Administrator)
1. On your SAP Exchange Infrastructure central instance host, start the J2EE Engine administration tool.
2. Choose Cluster u2192 Server u2192 Services u2192 JCo RFC Provider
3. In the section RFC destination, enter exactly the same program ID and gateway options for AI_RUNTIME_JCOSERVER that you used in the step Maintaining the RFC connection above. Additionally, set the number of processes to 10.
4. In the section Repository, do the following:
a. Enter the parameter for the SAP XI host: Application Server, System Number, Client and Language.
b. For User and Password maintain the login parameters for the user SAPJSF.
c. Select the flag Unicode.
6. Choose Set.
7. Repeat the steps 3 u2013 6 for the remaining destinations:
Destination
Values
AI_DIRECTORY_JCOSERVER
u2022 Corresponding values from SM59
u2022 Number of processes: 10
LCRSAPRFC
u2022 Corresponding values from SM59
u2022 Number of processes: 3
SAPSLDAPI
u2022 Corresponding values from SM59
u2022 Number of processes: 3
Testing the RFC Destination
After you have maintained all RFC destinations in both the ABAP and Java environment, you can check all the connections above as follows:
1. Call transaction SM59 again.
2. Open your RFC destination.
3. Choose Test Connection. No error should be displayed.
This will solve your problem.
Thanks

RFC connection error when registering PROGRAM ID.

Points to be rewarded for any kind of small help.

Thanks Ramesh.
I followed the blog. Here are the steps that I did.
RFC destination:
1. To create the RFC go to TCODE: SM59 -> Done2. Create new destination of type T (TCP/IP) -> Done
3. Make sure you select Registered Server Program option before writing your program ID -> Done
4. Write you program ID (remember it's case-sensitive) -> gave the SID name
5. In the gateway host and gateway service write the values of your "Application system" - business system (not the XI server) -> Typed the gateway hostname and gateway service "sapgw<instance no>", that I got from SMGW.
But still I face the same problem. It get the following error:

I tried the following fixes spread across different threads in this Expert Forums:
1. Someone said network problem. I rebooted, restarted the install and even redo it.
2. Another suggestion was to use caps on the password. Didnt work.
3. One suggestion was to update the keydb.xml file. However, I could find such property name:
search for the table t_SAPComponent_SAPSystemLogon_SHARED
then look for <fld name="pPW">, <properties>,
<property name ="GUIENG_USER_INPUT" and set the value
"GUINEG_TRUE" to "GUIENG_FALSE".
4. I even used the ddic password 19920706 which is supposed to be the default.
5. Restarted the instance and applied all the fixes above.
Does anyone know what is going on base on the logs above? Thanks.

try moving all your install disk onto local file system then rerun the install. That might work....
