Steps to Re-configure Oracle Fusion Middleware 11.1.1.9 Components for Oracle E-Business Suite specially after clone

 

Overview

OPMN will log the following errors when attempting to start the patched opmn process with a default MD5withRSA signed certificate:

[opmn] [ERROR:1] [] [ons-secure] Connection server SSL set credentials failed (43084)
[opmn] [ERROR:1] [222] [ons-secure] SSL initialization failed

Generating and Deploying a New Wallet for TLS Enabled Release 12.2 Environments


Log in as the user that owns the application tier installation (this is usually applmgr or oracle).

Source the run file system environment and the $FMW_HOME/SetWebtier.env file.
  • $ source <EBS base install directory>/EBSapps.env run
  • $ source $FMW_HOME/SetWebtier.env
For a new Oracle E-Business Suite Release 12.2 installation, all steps must be performed on the run edition file system, which is sourced by running the following command:
  • $ source <EBS base install directory>/fs1/EBSapps/appl/APPS<CONTEXT_NAME>.env

Set an alias for the correct orapki.
  • $ alias orapki=$FMW_HOME/oracle_common/bin/orapki

Create a new wallet with an acceptable self-signed certificate in $HOME/ss. For example:


$ mkdir ~/ss
$ cd ~/ss
$ orapki wallet create -wallet ./ -auto_login_only
$ orapki wallet add -wallet . -dn "CN=FMWSmallCircleOfTrust" -asym_alg RSA -keysize 2048 -sign_alg sha256 -self_signed -validity 3652 -auto_login_only
$ orapki wallet display -wallet .


The last command (orapki wallet display -wallet .) allows you to verify that the wallet was properly created.

Find the instanceName of this environment and save in an environment variable for later use.


$ tr < $CONTEXT_FILE '<>' '  ' | awk '/"s_ohs_instance"/ {print $(NF-1)}'
EBS_web_OHS1
$ iName=$(tr < $CONTEXT_FILE '<>' '  ' | awk '/"s_ohs_instance"/ {print $(NF-1)}' )
$ cd $FMW_HOME/webtier/instances/$iName
Find the default wallets used by this instance.
$ find . -name cwallet.sso | fgrep -v /webgate/
./config/OPMN/opmn/wallet/cwallet.sso
./config/OHS/EBS_web/proxy-wallet/cwallet.sso
./config/OHS/EBS_web/keystores/default/cwallet.sso
Verify that each wallet only contains the self-signed certificate.
$ find . -name cwallet.sso | fgrep -v /webgate/ | while read w ; do echo -e "\n$w"; orapki wallet display -nologo -wallet $w ; done
If it is a default wallet, each wallet should list one "User Certificate" and an identical "Trusted Certificate", as shown in the following example:
./config/OPMN/opmn/wallet/cwallet.sso
Requested Certificates:
User Certificates:
Subject: CN=Self-Signed Certificate for EBS_web_OHS1\20,OU=OAS,O=ORACLE,L=REDWOODSHORES,ST=CA,C=US
Trusted Certificates:
Subject: CN=Self-Signed Certificate for EBS_web_OHS1\20,OU=OAS,O=ORACLE,L=REDWOODSHORES,ST=CA,C=US

Note: If a wallet is not a default wallet, make a backup copy of that wallet before proceeding.
Copy the new SHA-256 signed wallet to all default wallet locations.

$ find . -name cwallet.sso | fgrep -v /webgate/ | while read w ; do echo $w; cp -p ~/ss/cwallet.sso $w ; done
You have now copied the new self-signed wallet to the default locations in the run file system. This avoids modifying the OPMN and OHS configuration files to point to a different wallet (or wallet directory).
Prepare to make the changes to the patch file system by modifying adop_sync.drv located under $APPL_TOP_NE/ad/custom to include the following:
#Oracle HTTP Server Wallet - cwallet.sso
rsync -zr %s_current_base%/FMW_Home/webtier/instances/%s_ohs_instance%/config/OHS/%s_ohs_component%/keystores/default/cwallet.sso %s_other_base%/FMW_Home/webtier/instances/%s_ohs_instance%/config/OHS/%s_ohs_component%/keystores/default/cwallet.sso
#OPMN Wallet - cwallet.sso
rsync -zr %s_current_base%/FMW_Home/webtier/instances/%s_ohs_instance%/config/OPMN/opmn/wallet/cwallet.sso %s_other_base%/FMW_Home/webtier/instances/%s_ohs_instance%/config/OPMN/opmn/wallet/cwallet.sso
rsync -zr %s_current_base%/FMW_Home/webtier/instances/%s_ohs_instance%/config/OHS/%s_ohs_component%/proxy-wallet/cwallet.sso %s_other_base%/FMW_Home/webtier/instances/%s_ohs_instance%/config/OHS/%s_ohs_component%/proxy-wallet/cwallet.sso

The changes will be propagated to the patch file system when you perform the steps in Section 3 during the prepare phase (adop phase=prepare) of online patching and will take effect after a successful cutover (adop phase=cutover).


After this procedure is complete, do not remove or alter the updated adop_sync.drv file.


To use the Oracle Fusion Middleware Control Enterprise Manager (EM) Console at http://<app01>:7001/em to manage OHS, you may have to re-register OHS and its new certificate with Fusion Middleware Control. This must be done on both the run and patch file systems.

If you have determined that OHS reports as down in the Oracle Fusion Middleware EM Console, perform these steps to re-register OHS

a. Obtain the host, port, and user name variables for WLS Admin from CONTEXT_FILE:

$ aHost=$( tr < $CONTEXT_FILE '<>' '  ' | awk '/"s_wls_admin_host"/ {print $(NF-1)}' )
$ aPort=$( tr < $CONTEXT_FILE '<>' '  ' | awk '/"s_wls_adminport"/ {print $(NF-1)}' )
$ aUser=$( tr < $CONTEXT_FILE '<>' '  ' | awk '/"s_wls_admin_user"/ {print $(NF-1)}' )


b. Re-register OHS using the following commands:

$ cd $FMW_HOME/webtier/instances/$iName/bin
$ ./opmnctl unregisterinstance -adminHost $aHost -adminPort $aPort -adminUsername $aUser -instanceName $iName
$ ./opmnctl registerinstance -adminHost $aHost -adminPort $aPort -adminUsername $aUser

How to fix Oracle SQL Developer connection issue "Got minus one from a read call"

Image
 During connection from SQL Developer to EBS database got below error message: Status : Failure - Test failed: IO Error: Got minus one from a read call Following solution can be done : 1. Go to directory $ORACLE_HOME / network / admin 2. Modify sqlnet.ora file with following parameter : tcp.validnode_checking = no 3. If you don 't want to disable this, you can put the machine names as follows: tcp.invited_nodes=(machine1, machine2) 3. Bounce the listener. Due to security enhancements it is not good to put tcp.validnode_checking = no or comment out will through error when we start listener like below: Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=shsebs7idb1.appsolworld.com)(PORT=1522))) TNS-00584: Valid node checking configuration error TNS-12560: TNS:protocol adapter error Better plan is to add localhost or IP address of client (Local Computer) in the sqlnet.ora file That will solve the problem NAMES.DIRECTORY_PATH=(TNSNAMES, ONAMES, HOSTNAME) SQLNET.EXPI

How to troubleshoot Long Running Concurrent Request in EBS 12.2

 The following points need to answer before jumping into troubleshooting: Are there any recent code changes done in the concurrent program?           Check long_running_sid and verify the recent code change of last_ddl_timestamp after a             discussion with the developer. Was this running long in the last few run as well, or was this time only?            ==> Check the program history. How much time does it take to complete?           Once again program history can give us some idea. Are these jobs fetching higher data compared to the last run           ===> Confirm on data change . Query Plan change will indicate this issue. Does this job runs at any specific time or it can be run anytime           ===> The nature of the job can help to understand the job's nature. Does this job fetch data using DB Link          ====> Check whether the DB link is involved or not. The below-given approach would help to conclude the gray areas.

How to autopopulate user_guid in fnd_user table ( EBS Blank Page)

  Issue:  EBS Local Login url is working fine. When accessing sso url, users are getting error as below appended to the url. And login page will be blank. One of the reason could be : OAM Authentication is fine but during authorization process, OAM is unable to map guid from oid to user_guid in fnd_user. This can be due to user_guid being null in fnd_user table. As per the process, when user logins for the first time, user_guid need to be populated automatically (from oid) Query guid from oid and update fnd_user table with that. ldapsearch -h oidhost.appsolworld.com -p 3060 -D "cn=orcladmin" -w orcladmpwd -b "cn=Users,dc=dc,dc=online,dc=org" -s sub "(uid=$1)" orclsamaccountname krbprincipalname mail orcluserprincipalname orclguid Pass userid to this command which gives guid along with other details.

The Server is not able to service this request: [Socket:000445]Connection rejected, filter blocked Socket, weblogic.security.net.FilterException

Image
  Connection Filters allow one to deny access to UNWANTED Connections at the network level. Connection Filters can be used to protect server resources on individual servers, server clusters, or an entire internal network or Intranet. Connection filters are particularly useful when using the Administration port. Depending on the network firewall configuration, it may be possible to use a connection filter to further restrict administration access. A typical use might be to restrict access to the Administration port to only the servers and machines in the domain. WebLogic Server provides a default connection filter called  weblogic.security.net.ConnectionFilterImpl . This default connection filter accepts all incoming connections except the ones defined in the Administration Console as a Connection filter rule. Custom connection filters may be written  by implementing the classes in the weblogic.security.net package. This post will demonstrate the steps to configure Weblogic Connection F
