Oracle EBS登录页面显示空白

重启应用

但尝试以上操作后都无法解决问题，只好在ORACLE METLINK上搜索相关案例

查到ID 2036519.1和我相似

登录ebs的apps数据库

SQL> SELECT fnd_web_sec.validate_login(‘GUEST‘,‘ORACLE‘) FROM dual; 

FND_WEB_SEC.VALIDATE_LOGIN(‘GUEST‘,‘ORACLE‘) 
-------------------------------------------------------------------------------- 
N 

SQL> select fnd_message.get from dual;

GET
--------------------------------------------------------------------------------
Oracle error -29548: ORA-29548: Java system class reported: release of Java syst
em classes in the database (12.1.0.2.161018 1.6) does not match that of the orac
le executable (12.1.0.2.170117 1.6) has been detected in FND_WEB_SEC.VALIDATE_PA
SSWORD.

从messige可知是由于oracle的补丁和数据库中的post install的补丁不一致导致的，是由于oracle程序补丁更新了，但没有post install，想起来所回退时间之后又打了最近季度的PSU补丁，回退后导致数据库没有post install

重新post install下psu补丁

SQL>sqlplus / as sysdba

SQL>shutdown immediate

SQL>startup upgrade

$cd $ORACLE_HOME/Opatch/

$./datapatch

post install之后重启数据库，再次查询fnd_web_sec.validate_login(‘GUEST‘,‘ORACLE‘)的值

SQL> select fnd_web_sec.validate_password(‘GUEST‘,‘ORACLE‘) from dual;

FND_WEB_SEC.VALIDATE_PASSWORD(‘GUEST‘,‘ORACLE‘)

重启应用，打开页面正常

以下为oracle metlink上的说明

APPLIES TO:

Oracle Applications Technology Stack - Version 12.1.3 to 12.1.3 [Release 12.1]
Information in this document applies to any platform.

SYMPTOMS

E-Business Suite 12.1.3 Applications Technology Stack, IAS for Applications Technology issues

Users unable to login to the application, and when attempting to login the following errors are reported in the log files:

15/07/20 14:13:32.570 html: chain failed
javax.servlet.ServletException: java.lang.RuntimeException: Guest user/pwd does not exist or match: GUEST/ORACLE

       at oracle.jsp.runtimev2.JspPageTable.service(JspPageTable.java:473)
       at oracle.jsp.runtimev2.JspServlet.internalService(JspServlet.java:594)


The issue can be reproduced at will with the following steps:

1. Restart the system after 2015 PSU patching.

2. Login to E-Business Suite.

CHANGES

2015 PSU patching was performed and/or other system updates were completed.

CAUSE

April 2015 PSU was applied on the shared RDBMS oracle_home, but the RDBMS post install steps were not completed (Per Note 1933286.1#aref_section213) .

The 2015 PSU patch contains ojvm patches for the database JVM, which is also used by E-Business suite for authentication.  To confirm the issue test GUEST password validation via the following SQL:

SQL> SELECT fnd_web_sec.validate_login(‘GUEST‘,‘ORACLE‘) FROM dual; 

FND_WEB_SEC.VALIDATE_LOGIN(‘GUEST‘,‘ORACLE‘) 
-------------------------------------------------------------------------------- 
N 

SQL> select fnd_message.get from dual; 

GET 
-------------------------------------------------------------------------------- 
PASSWORD_INVALID 
 

SOLUTION

To implement the solution test the following steps in a development instance where the problem can be reproduced and then migrate accordingly:

cd $ORACLE_HOME/rdbms/admin
sqlplus /nolog
SQL> CONNECT / AS SYSDBA
SQL> STARTUP
SQL> @catbundle.sql psu apply
SQL> QUIT
