Changes:
JRE updates were installed recently.
Cause:
The wrong value is set for “s_forms_tracking_cookies” in the context file.
Solution:
To resolve the issue, test the following steps in a development instance and migrate accordingly:
1. Login EBS > OAM > System Configuration > AutoConfig
2. Modify the following value:
＜before＞
<forms_tracking_cookies oa_var=”s_forms_tracking_cookies”>disabled
＜after＞
<forms_tracking_cookies oa_var=”s_forms_tracking_cookies”>enabled
3. Stop the AP tier service
$ADMIN_SCRIPTS_HOME/adstpall.sh
4. Run Autoconfig on AP Node.
5. Start AP tire service
$ADMIN_SCRIPTS_HOME/adstrtal.sh
Note:
After the above changes ensure users restart the client PC and clear browser and jre cache. Otherwise the following error may be received.
