Replace http return code

Can WLS 10.3.x with certain settings return http-code=503 in a situation where under normal settings it returns http-code=500?

Hi,
Yes, I understand the issue.
However, error 500 doesn't mean that the server is unavailable. The server could return 500 for different reasons, and the issue could be related to the application behaviour.
I don't know exactly what kind of application you have, but if we think of webservices for example, whenever the app returns a SOAPFault, HTTP 500 is also returned. In some cases, it could be just a payload validation error.
Having said that, if you can identify an error condition when you believe the server is unavailable due to specific exception, you could monitor either Weblogic resources using JMX or the log files, and write scripts to either stop/restart the server.

Fabio.

JSP and HTTP return code

I am new at developing jsp, and I am looking for a way to send an HTTP return code under a specific condition.
for ex :
if(data==ok)
HTPP_return_code = 200;
else
HTPP_return_code = 500;
Is it possible ?

Within your JSP you can use the sendError method on the response object.
e.g.
if (data == ok) {
response.sendError(HttpServletResponse.SC_OK);
} else {
response.sendError(HttpServletResponse.SC_INTERNAL_SERVER_ERROR);
} See http://java.sun.com/j2ee/1.4/docs/api/javax/servlet/http/HttpServletResponse.html
for possible HTTP return code constants.

Is there a way to direct requests based on HTTP return-code checking?

I'd like to implement a policy based on return-code. The algorithm is as below,
If HTTP return-code == 500 to 600
serverfarm1
else
serverfarm2
We have a CSM V3.2. Can someone tell me if this is doable? If yes, would you please tell me how.
Appreciation, Q.Xie

The solution I suggested is still what I recommend.
What you have to do is split your serverfarm in multiples instances. One for HTTP and another one for the rest of your applications. Or you could do one for each application.
The serverfarm for HTTP will have the HTTP probe and will go down when the response is 500-600.
The other serverfarm(s) will not use the same HTTP probe and should not go down based on the response code.
ie:
serverfarm WEB
real 10.10.10.10
ins
real 20.20.20.20
ins
probe http
serverm ALL
real 10.10.10.10
ins
real 20.20.20.20
ins
no probe
vserver web
vip 1.1.1.1 tcp 80
serverfarm WEB backup WEB_B
vserver all
vip 1.1.1.1 any
serverfarm ALL
Hope this helps.

HTTP Return Code on CSM causes IP Sticky does not work

I have CSM running on 3.1(1a).
I configured HTTP Return Code Checking:
map HTTPCHECK retcode
match protocol http retcode 404 404 action remove 5 reset 60
And apply it to the following web server serverfarm:
serverfarm DCMSWEB
nat server
no nat client
predictor leastconns
retcode-map HTTPCHECK
real 10.1.31.1
inservice
real 10.1.31.2
inservice
I also configure IP sticky for my web server:
sticky 2 netmask 255.255.255.255 timeout 60
And apply that sticky to the virtual server:
vserver DCMSWEBHTTP
virtual 10.1.30.100 tcp www
serverfarm DCMSWEB
sticky 60 group 2
replicate csrp sticky
replicate csrp connection
persistent rebalance
inservice
But, the problem is my sticky does not work if I apply HTTP return code checking on the serverfarm.
"show mod contentswitchingmodule 8 sticky" does not show any IP sticky connection.
If I remove HTTP return code checking from serverfarm, my IP sticky is back to normal.
Has anyone encoutered this similar problem before?
Is this a bug on the CSM software?

This is a new bug.
The workaround is to use the command 'client 0.0.0.0 /0' under the vserver.

CSM HTTP return code checking

Hey again.
I have been looking into the CSM return code checking feature as suggested by this forum. This is a little closer to what I am looking for but I have question about what happens when there is a failure.
If a 500 code for HTTP is seen three times, for example, and the server is removed from the farm, is the original request from the client tried on the next server? Or is a reset sent back to the client, or the original code, and the client must try again.
I am trying to understand if the client will notice if the CSM noticed X number of a particular error and removed the server from the farm.
Thanks for any help!

I think you are mixing two things up(Inband health monitoring & HTTP return code checking).
The "Inband health monitoring" feature checks for both RSTs from a server and the failure of the server to respond to a SYN. If a SYN ACK response to a SYN is not received,the TCP portion of the code will perform several retries of a SYN before timing it out.
It is configured as follows
CSM(config-module-csm)# serverfarm xyz
CSM(config-slb-sfarm)# health retries 10 failed 50
(Retries are the number of abnormal end sessions that the CSM will tolerate before removing a real server from service. The failed time is the number of seconds that the CSM waits before reattempting a connection to a real server that was removed from service by inband health checking.)
"HTTP Return Code checking" is the CSM feature that can be configured to take a server out of use in response to receiving specific return codes.
When HTTP return code checking is configured, the CSM monitors HTTP responses from all balanced HTTP connections and logs the occurrence of the return code for each real server. The CSM stores return code counts. When a threshold for a return code is reached, the CSM may send syslog messages or remove the server from service.
Unlike "Inband Health monitoring", "Http Return code checking" feature has a small (estimated in 10-15%) impact on CPS setup rate, since it requires parsing L5 information in the server-to-client direction.
If the server is taken out of service, Client's request will be loadbalanced among available servers.

HTTP Return Code Checking on ACE

Hey there.
I have a question regarding return code checking for a serverfarm on ACE. I am looking to have the ability to monitor a client's session real-time and monitor return codes passing back from the origin servers to the client.
For example, if during a client's session there is a single HTTP 500 error code sent from server to client, the intercept that response and first retry the request on a different server in the farm. Or perhaps only if I see three 500 error codes in 30 seconds. Something like that.
From what I can tell from the docs the retcode check command for a serverfarm is maybe only for statistical purposes?
Thanks for any help.
/ahuffer/

In ACE return codes checking is only used to count number of return codes from Rservers. Unlike CSMs (where return codes were used for inband health monitoring) ACE is not using them for load balancing or inband health
monitoring. Once you enable return code checking and counting you can then display the return code statistics per serverfarm
for example
serverfarm host serverfarm1
retcode 200 499 check count
rserver real1
inservice
rserver real2
inservice
show serverfarm serverfarm1 retcode
serverfarm : serverfarm1
rserver : real1
np : 1
return code action total count
+------------+--------+------------+
200 count 100
201 count 0
202 count 0
203 count 0
204 count 0
205 count 0
206 count 0
498 count 0
499 count 0

Hi
Can you check this out?
Transaction SXMB_ADM  Integration Engine Configuration
For an application system you have to maintain the role of the business system as an application system. Set the corresponding Integration Server as an HTTP destination (for example, dest://INTEGRATION_SERVER). Create the destination in transaction SM59 and set the type to HTTP Connections to R/3 System. Test the connection by using the Connection Test button; you should get HTTP 500 u2013 Empty HTTP Request received, because no u201Ereal‟ XML document is sent during this test.
A HTTP return code 500 (Internal Server Error) is OK.

Windows Azure Pack - Server returned HTTP response code: 500 error while accessing the public tenant API

Hi,
We are facing the following error while trying to access the given Windows Azure Pack Public tenant API to query the virtual machines list along with network adaper details -
java.io.IOException: Server returned HTTP response code: 500 for URL: https://<hostname>:30006/<subscription-id>/services/systemcenter/vmm/VirtualMachines?$expand=VirtualNetworkAdapters&$top=10000&$skip=0
The response is proper when we access the following URL -
https://<hostname>:30006/<subscription-id>/services/systemcenter/vmm/VirtualMachines
Only on adding the $expand=VirtualNetworkAdapters, url parameter we are getting the above error.
Where can we check for the error logs on the Azure Pack server ? We checked for the logs using Windows Event Viewer but did not find any for the public tenant API.
What should be the cause for such an error and how can we fix this to get the proper data?
Thanks in advance.

Yes, we tried this, $top=10&$skip=0 works for the following url
https://<hostname>:30006/<subscription-id>/services/systemcenter/vmm/VirtualMachines?$top=10&$skip=0
It is only when we add $expand=VirtualNetworkAdapters,
the server returns the mentioned error response -
URL for which the server returns the 500 error -
https://<hostname>:30006/<subscription-id>/services/systemcenter/vmm/VirtualMachines?$expand=VirtualNetworkAdapters&$top=10&$skip=0
Can
you point to the error logs for Windows Azure Pack and SPF ?

Error in Webservice Call HTTP error (return code 404, message conn failed)

Hi
We wish to call a standard EP7 webservice through ABAP.
When we try to create consumer proxy , we get the following error.
HTTP error (return code 404, message "conn failed")
Message no. SPRX090
==> Display Error Document
If you want to generate a proxy for an external WSDL document by specifying a URL, check that the proxy settings of the system are correct (transaction SICF - Client - Proxy Settings). If you want to generate a proxy for an XI Repository object, check the connection to the Enterprise Services Builder as follows:
Check List for Setting Up a Connection to the Service Repository
1. The address of the Enterprise Services Repository must be known in the SAP system
Check with report SPROX_CHECK_IFR_ADDRESS
The address is taken from the following parameters in the exchange profile ('Connections' section):
com.sap.aii.connect.repository.name: Server (for example,pwdf0436)
com.sap.aii.connect.repository.httpport: Port (for example, 1080)
com.sap.aii.connect.repository.contextroot: Root (for example,rep)
The logon data is also read from the exchange profile ('ApplicationSystem' section):
com.sap.aii.applicationsystem.serviceuser.name: User
com.sap.aii.applicationsystem.serviceuser.pwd: Password
As an alternative to using the exchange profile, you can maintain the RFC destination SAP_PROXY_ESR. If this RFC destination is maintained it will be used by the proxy generation in place of data from the exchange profile to access the Service Repository. In this case, the Exchange Profile will even not be read.
The RFC destination has to be set up using transaction SM59 and should look like this:
RFC Destination: SAP_PROXY_ESR
Connection Type: G (HTTP Connection to External Serv)
Description1: ESR for Proxy Generation
Target Host: esr_host
Service No: 1080
Path Prefix: rep
Logon and Security:
Basic Authentication: active
User: esr_user
Password: esr_password
2. The HTTP Framework of the Web Application Server must function
Check with report SPROX_CHECK_HTTP_COMMUNICATION
If necessary, contact your system administrator. Please be aware of the fact, that the HTTP framework is depending on the application server. Thus the result of the report may differ for different application servers.
3. Proxy generation must interpret the data of the Enterprise Services Repository correctly
Check with report SPROX_CHECK_IFR_RESPONSE
you can also login in dev and go to Xn se91
enter msg id SPRX and msg no 090
select the message and click on long text..
you get the same message in a formatted manner..
How to get rid of this ?

but now it doesn't works with URL url = new URL("http://www.infoamistades.net/load.do");
and putting thia addrees to the browser it works, of course..
no changes at the server, not firewalls.. (?!?!)
thanks,

Hi,
Actually I am also having exactly same problem that you mentioned, I am new to the world of servlets. I could not get what you mean by "put variable in the request" Please tell me exactly what to do to solve this problem.
