APEX IMAGE ISSUE (503 Unavailable Error raising while access or load the images through Apex user).


Requirements:
--------------
Apex 5.1.3
ORDS 3.0.9
Glassfish 3.0

Error:
======
1.It will raised in ORDS with Apex only.
2.The developer got 503 Unavailable Error while accessing or load the image through apex link.
3.Applications are working fine , but the icons(buttons , labels etc) are not showing in the application front end.


Solution:
=========

1.Check the Apex users account status and ensure all the apex users are open status.

SQL> SELECT USERNAME , ACCOUNT_STATUS FROM DBA_USERS WHERE USERNAME LIKE '%APEX%';

2.APEX_REST_PUBLIC_USER is the user can have the privileges to access all the componenets in APEX with ORDS GLASSFISH.

3.Grant the privilege to WORKSPACE SCHEMA (Application Schema) connect through APEX_REST_PUBLIC_USER.


SYNTAX :
ALTER USER <USERNAME> GRANT CONNECT THROUGH APEX_REST_PUBLIC_USER.

Example:

Workspace schema = FMS
Workspace        = FMS

ALTER USER FMS GRANT CONNECT THROUGH APEX_REST_PUBLIC_USER.

Now we can see all the images are working fine.

Database Security Assessment Tool.

The Oracle Database Security Assessment Tool (DBSAT) analyzes database configurations, users, their entitlements, security policies and identifies where sensitive data resides to uncover security risks and improve the security posture of Oracle Databases.

The Database Security Assessment Tool (DBSAT) consists of the following components:

1. Collector
2. Reporter
3. Discoverer

1. Collector.

l The collector should be run on the database server.
l Collector gathers information from the database and generates a JSON file containing all the information.

2. Reporter

l DBSAT Reporter will take as input the file generated by the collector (json or zip file).
l The Reporter and will produce one zip file containing three reports in different formats: HTML, spreadsheet, and text.

3. Discoverer

l The discoverer is essentially a separate Java-based tool that checks for sensitive data in the database.
l First you need to create a dbsat.config file. You can call it anything you want as you will be referencing it explicitly later.


1. DBSAT INSTALLATION:

Requirements:
1. DBSAT Tool zip.
2. Python 2.5 and above.
3. Java 1.8 and above.

A) Create specific DBSAT Directory.

When try to start up an Oracle database, the below errors occur:

ORA-27125: unable to create shared memory segment
Linux-x86_64 Error: 28: No space left on device
Additional information: 3773
Additional information: 3221225472

CAUSE

Kernel parameter kernel.shmall is not set properly.

RESOLUTION

Make sure kernel.shmall  is given the appropriate value.

1)  Calculate the value of shmall.

# getconf PAGE_SIZE 4096 Shmall=total size of the SGAs /PAGE_SIZE.

If the total SGA size is 480GB, then it would be 1024 * 1024 * 1024 * 480 / 4096 = 125829120

2) Edit /etc/sysctl.conf

kernel.shmall = 125829120

3) Apply the change

# sysctl -p   4) Check shmall value after change.
# sysctl -A | grep shmall

5) Start up database successfully.

ORA-02374: Conversion error loading table during impdp

Error:

ORA-02374: conversion error loading table  "SCHEMA"."TABLENAME"
ORA-12899: value too large for column ENAME (actual: 66, maximum: 64)
ORA-02372: data for row: ENAME : 0X'45737061C3B16F6C2020202020202020202020202020202020'


More About the Error:

1.        Used expdp and created a dump for the table: SCHEMA.TABLENAME
2.        While doing a impdp on the target database :
ORA-02374: conversion error loading table "SCHEMA"."TABLENAME"
ORA-12899: value too large for column ENAME (actual: 66, maximum: 64)
ORA-02372: data for row: ENAME : 0X'45737061C3B16F6C2020202020202020202020202020202020'

Solution:

When you describe the table, you will see that the column ENAME is char(64):

SQL> desc  SCHEMA.TABLENAME
 Name                                      Null?    Type
 ----------------------------------------- -------- ----------------------------
 ENUM                                     NOT NULL  NUMBER(5)
 ENUM1                                    NOT NULL  NUMBER(5)
 ENUM2                                              NUMBER(5)
 ENUM3                                              NUMBER(5)
 ENAME                                              CHAR(64)

Execute the below to modify the column of the table:

SQL> alter table SCHEMA.TABLENAME modify ENAME CHAR(66);

Table altered.

Now perform the import using the below command:

impdp directory=DATA_PUMP_DIR dumpfile=ENAME.dmp logfile=ENAME.log tables=SCHEMA.TABLENAME table_exists_action=truncate

Troubleshooting ASM Proxy instance startup

I had trouble starting ASM proxy instance on  one of the nodes in my  2 node flex cluster having nodes host01 and host02. As a result I could not access the volume I created on an ASM  diskgroup.  This post explains  how I resolved it.
While connected to host01, I created a volume VOL1 on DATA diskgroup with corresponding volume device /dev/asm/vol1-106 .

[grid@host01 root]$ asmcmd volcreate -G DATA -s 300m VOL1

[grid@host01 root]$ asmcmd volinfo -G DATA VOL1

Diskgroup Name: DATA

Volume Name: VOL1
Volume Device: /dev/asm/vol1-106
State: ENABLED
Size (MB): 320
Resize Unit (MB): 32
Redundancy: MIRROR
Stripe Columns: 4
Stripe Width (K): 128
Usage: ACFS                                                             Mountpath:
I created  ACFS file system on the newly created volume

[root@host01 ~]# mkfs -t acfs /dev/asm/vol1-106
I also created corresponding mount point /mnt/acfsmounts/acfs1 on both the nodes in the cluster.
root@host01 ~]# mkdir -p /mnt/acfsmounts/acfs1

root@host02 ~]# mkdir -p /mnt/acfsmounts/acfs1
When I tried to mount the volume device, I could mount the volume device on host01 but not on host02 .

[root@host01 ~]#mount -t acfs /dev/asm/vol1-106 /mnt/acfsmounts/acfs1

[root@host01 ~]# mount | grep vol1

/dev/asm/vol1-106 on /mnt/acfsmounts/acfs1 type acfs (rw)

[root@host02 ~]# mount -t acfs /dev/asm/vol1-106 /mnt/acfsmounts/acfs1

mount.acfs: CLSU-00100: Operating System function: open64 failed with error data: 2
mount.acfs: CLSU-00101: Operating System error message: No such file or directory

The corresponding volume device was visible on host01 but not on host02
[root@host01 ~]# cd /dev/asm
[root@host01 asm]# ls
vol1-106

[root@host02 ~]# cd /dev/asm
[root@host02 asm]# ls
Since ADVM / ACFS utilize an ASM Proxy instance in a flex cluster to access metadata from a local /  remote  ASM instance ,  I checked whether ASM Proxy instance was running on both the nodes and realized that whereas ASM Proxy instance was running on host01, it  was not running on host02

 TNS-12560: TNS:protocol adapter error  TNS-00583: Valid node checking: unable to parse configuration parameters


I  Received following errors when trying to startup my listener. I verified the listener.ora and sqlnet.ora files and everything seemed to look normal.

I had below line in my sqlnet.ora file.

[oracle@Linux03 admin]$ cat sqlnet.ora_bak
# sqlnet.ora Network Configuration File: /u01/app/oracle/product/12.1.0.2/db_1/network/admin/sqlnet.ora

ENCRYPTION_WALLET_LOCATION =
  (SOURCE =(METHOD = FILE)(METHOD_DATA =
    (DIRECTORY = /u01/app/oracle/admin/$ORACLE_SID/encryption_keystore/)
   

Solution (in my case): Removing the ENCRYPTION_WALLET_LOCATION info did the trick for me.

1.Check with the DBA about the field LFILE_SIZE in the table FND_CONCURRENT_REQUESTS is set to what value.
2.Check if log file is created properly with LFILE_SIZE > 0.
  If LFILE_SIZE is not set then set the value >0 and check if issue can be replicated.
3.Check with their DBA to delete old trace/log files so that enough space is present on the slot.
4. Check if issue can be replicated now.

5.Either apply the latest version of (invprg.ldt), with patch <27656545:R12.INV.C> OR action below
A. Take the back up of the existing file invprg.ldt
($INV_TOP/patch/115/import/US).
B. download the newly uploaded file in binary format.
C. Apply the newly downloaded file to the instance using fndload:

FNDLOAD apps/apps@mm1dv210 0 Y UPLOAD $fnd/patch/115/import/afcpprog.lct

Opatch fails with Lock file error

While applying Oracle Patch, Opatch reports the below error :

OUI-67064:OPatchSession cannot load inventory for the given Oracle Home /ora01/app/oracbr/product/11.2.0/dbhome_1. Possible causes are:
                               No read or write permission to ORACLE_HOME/.patch_storage
                               Central Inventory is locked by another OUI instance
                               No read permission to Central Inventory
                               The lock file exists in ORACLE_HOME/.patch_storage
                               The Oracle Home does not exist in Central Inventory
[Dec 20, 2013 8:29:05 AM]    OUI-67073:UtilSession failed: Lock file left by a different patch, OPatch will not try re-using the lock file.




Note : It has been noticed that opatch lock error also leads to the error "OPatch failed with error code 255"



In earlier releases, error used to look like:

Problems with the lock file
Lock file exists, details are:
Interim Patch is holding the lock from this patch xxxxxx,
probably due to previous unsuccessful operation

ERROR: OPatch failed during pre-reqs check



CAUSE
 When Opatch is invoked, it creates patch_locked file in $ORACLE_HOME/.patch_storage during its execution.

 If the patch application is interrupted or cancelled, this file gets retained under /.patch_storage directory. Hence, On an an attempt to re-apply the patch, the presence of patch_locked file doesnt allow further processing and throw error.


SOLUTION
1. Check if the file "patch_locked" is present in the directory $ORACLE_HOME/.patch_storage

2. If present, rename, move or remove the patch_locked file from $ORACLE_HOME/.patch_storage

3. Re-apply the patch

How To Create An OCM Response File.

January 25, 2019, 1:49 am
$

During patching, Opatch tool may ask for an OCM (Oracle configuration manager) response file.

OCM can collect the configuration of your servers and send it to Oracle support.  Oracle support staff will use it when you open a service request. With OCM, you’ll get better and faster response from Oracle support. You can also view your configuration on metalink. Oracle can suggest you updates or patches according to your configuration. You can even use OCM in disconnected systems (where there is no internet connection).

Although it is useful, using OCM is not mandatory. You can still get support from Oracle without OCM. However, during patching, opatch utility may ask for an OCM response file.

How to create an OCM response file?

Opatch utility ships with a script file named “emocmrsp” which is used for creating a response file. “emocmrsp” script will ask your metalink account information and your internet connection information and store it in a response file named “ocm.rsp”.

“emocmrsp” script is found  under “$ORACLE_HOME/OPatch/ocm/bin/” directory. Simply execute this script (as root or oracle user) and enter the required information when prompted.

$ cd $ORACLE_HOME/OPatch/ocm/bin/

$ ./emocmrsp

This post is to define "How to attach ebs 10.1.2 oracle home to central inventory"


bash-3.2$ opatch apply

Oracle Interim Patch Installer version 1.0.0.0.64
Copyright (c) 2011 Oracle Corporation. All Rights Reserved..

Oracle recommends you to use the latest OPatch version
and read the OPatch documentation available in the OPatch/docs
directory for usage. For information about the latest OPatch and
other support-related issues, refer to document ID 293369.1
available on My Oracle Support (https://myoraclesupport.oracle.com)

Oracle Home           : /a01/appstier/UAT/fs2/EBSapps/10.1.2
Oracle Home Inventory : /a01/appstier/UAT/fs2/EBSapps/10.1.2/inventory

Creating log file "/a01/appstier/UAT/fs2/EBSapps/10.1.2/.patch_storage/18752577/Apply_18752577_11-25-2017_09-57-56.log"

The Oracle Home /a01/appstier/UAT/fs2/EBSapps/10.1.2 is not registered with the Central Inventory.  OPatch was not able to get details of the home from the inventory.

ERROR: OPatch failed because of Inventory problem.

When we apply patch in oracle home, OPatch checks for the inventory to understand the patch detail which already present. It gives the error above if it does not find any patch details. Since oracle home is not registered with central inventory, opatch could nt get any of the patch details thus it threw an error. We need to attach this particular oracle home to central inventory in order to overcome this error. This is one of the method to overcome this error.

bash-3.2$ cat /var/opt/oracle/oraInst.loc
inventory_loc=/var/opt/oracle/oraInventory
inst_group=dba

Source env file

bash-3.2$ cd $ORACLE_HOME/oui/bin/

EBS R12 Login Page Is Not Coming Up - java.lang.RuntimeException: Guest user/pwd does not exist or match: GUEST/ORACLE

January 25, 2019, 1:52 am
$
0
0

Acual Behavior
E-Business Suite (EBS) Production Instance Login page is not coming up, Instead a blank page is being displayed.

The issue can be reproduced at will with the following steps:
1. Type the EBS URL on browser.
2. It redirects to EBS login page.
3. But a blank page is displayed.



CHANGES


CAUSE
The root cause of the issue is with GUEST User and Password not in sync.

Running the below query, confirmed that GUEST user and password was not in sync


select fnd_web_sec.validate_login('GUEST','ORACLE') from dual;

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


Run following SQL to see more details on why above SQL reported No

select fnd_message.get from dual;
Also, confirmed with the below error on the oacore log

javax.servlet.ServletException: java.lang.RuntimeException: Guest user/pwd does not exist or match: GUEST/ORACLE



SOLUTION
Please perform the below steps

1. Shutdown the EBS services.

2. The only supported way to change the Guest user password is to update the context variable s_guest_pass and run AutoConfig, which runs the AdminAppServer utility internally.

Note : Restriction on the GUEST User Password : The GUEST User password cannot include the special character "#".

 3. Run Autoconfig on DB Node and then application node.

4. Execute the below sql again:

select fnd_web_sec.validate_login('GUEST','ORACLE') from dual;

Check whether query output is showing Y.

If no,  Please check whether the below error is seen on autoconfig log:

Unable to update GUEST_USER_PWD in database to GUEST/ORACLE - Password was not changed, this point to the DB parameter JAVA_JIT_ENABLED which is set as TRUE.

5. On 11g DB you need to have the below settings for EBS specifically, run the below sql

alter system set JAVA_JIT_ENABLED= FALSE scope = both;
6. Follow the steps 2 and 3 again.

7. Run the below command:

perl $FND_TOP/patch/115/bin/ojspCompile.pl --compile --flush -p 2

7. Check whether the compile completed successfully.

8. Restart the application services.

9. Retest the issue.

10. Migrate the solution to appropriate environments.
