Automatic Memory Management (AMM) in Oracle Database 11g R2


Identify Memory Requirement.

Following queries show you how to display the relevant memory information and how to combine with a single statement to calculate the required values.

-- Individual values.
COLUMN name FORMAT A30
COLUMN value FORMAT A10

SELECT name, value
FROM   v$parameter
WHERE  name IN ('pga_aggregate_target', 'sga_target')
UNION
SELECT 'maximum PGA allocated' AS name, TO_CHAR(value) AS value
FROM   v$pgastat
WHERE  name = 'maximum PGA allocated';

-- Calculate MEMORY_TARGET
SELECT sga.value + GREATEST(pga.value, max_pga.value) AS memory_target
FROM (SELECT TO_NUMBER(value) AS value FROM v$parameter WHERE name = 'sga_target') sga,
     (SELECT TO_NUMBER(value) AS value FROM v$parameter WHERE name = 'pga_aggregate_target') pga,
     (SELECT value FROM v$pgastat WHERE name = 'maximum PGA allocated') max_pga;

Assuming our required setting was 10G, we might issue the following statements.

CONN / AS SYSDBA
-- Set the static parameter. Leave some room for possible future growth without restart.
ALTER SYSTEM SET MEMORY_MAX_TARGET=15G SCOPE=SPFILE;

-- Set the dynamic parameters. Assuming Oracle has full control.
ALTER SYSTEM SET MEMORY_TARGET=10G SCOPE=SPFILE;
ALTER SYSTEM SET PGA_AGGREGATE_TARGET=0 SCOPE=SPFILE;
ALTER SYSTEM SET SGA_TARGET=0 SCOPE=SPFILE;
ALTER SYSTEM SET SGA_MAX_SIZE=0 SCOPE=SPFILE;


-- Restart instance.
SHUTDOWN IMMEDIATE;
STARTUP;

Once the database is restarted the MEMORY_TARGET parameter can be amended as required without an instance restart.

ETL Phases


Oracle BI Applications ETL processes includes three main phases: SDE, SIL, and PLP.
  • SDE stands for Source Dependent Extract. In this phase, SDE tasks extract data from the source system and SDS and stage it in staging tables. SDE tasks are source specific.
  • SIL stands for Source Independent Load. Load tasks transform and port the data from staging tables to base fact or dimension tables. SIL tasks are source independent.
  • PLP stands Post Load Process. PLP tasks are only executed after the dimension and fact tables are populated. A typical usage of a PLP task is to transform data from a base fact table and load it into an aggregate table. PLP tasks are source independent.

Customizing the WebLogic JVM heap size

How to customize Java Virtual Machine Settings in Oracle WebLogic Server

To achieve the best performance of the application and avoid performance bottlenecks problems ( “OutOfMemory”) you need to tune your Java Virtual Machine.
After fresh install of WebLogic Server and create a Domain (WebLogic or SOA or Forms or OBIEE etc.) you may set some properties such as Java “Heap size”, tune Java “Garbage Collection” and WebLogic Server start options.
Tune JVM settings
set the Variable USER_MEM_ARGS for the Admin Server and each Managed Server to tune the JVM Parameters. For Example:
USER_MEM_ARGS="-Xms1g -Xmx3g -XX:+UseParNewGC -XX:+UseConcMarkSweepGC -XX:NewSize=1g"


Where:
  • Xms1g: JVM initial heap size: In this example: 1 GB
  • Xmx3g: JVM maximal heap size: The heap can grow to 3 GB
  • -XX:+UseParNewGC: Uses parallel version of a younger generation

You can change the default JVM heap size to fit the needs of your deployment.
The default JVM heap size for WebLogic is 3GB. The size is set in the setDomainEnv.sh file for Linux or setDomainEnv.cmd for Windows, which is in the $DOMAIN_HOME/bin directory. The heap size is set with the -Xmx option.
To change the WebLogic JVM heap size:
  1. Open the setDomainEnv file in a text editor.
  2. Search for this comment line:
    For Linux:
    # IF USER_MEM_ARGS the environment variable is set, use it to override ALL MEM_ARGS values
    For Windows:
    @REM IF USER_MEM_ARGS the environment variable is set, use it to override ALL MEM_ARGS values
  3. Immediately after the comment line, add one of these lines:
    For Linux:
    export USER_MEM_ARGS="-Xms128m -Xmx3072m ${MEM_DEV_ARGS} ${MEM_MAX_PERM_SIZE}"
    For Windows:
    set USER_MEM_ARGS=-Xms128m -Xmx3072m %MEM_DEV_ARGS% %MEM_MAX_PERM_SIZE%
  4. Save the file.
  5. Re-start WebLogic Server.

"Create or Replace view" execution fails with "ORA-01720: grant option does not exist"

Developer complains that he can't run CREATE OR REPLACE VIEW for a particular view. He is getting error "ORA-01720: Grant Option Does Not Exist"
I searched online and didn’t find solution that fix my issue. Everyone was getting this error with a GRANT statement. I turned to My Oracle Support and found excellent note which saved my time.

Cause: view has incorrect grants.

Solution:
Remove all grants on the view or Drop and recreate the view

Reference: Post Upgrade To 11.2.0.4, "create or replace view" execution fails with "ORA-01720: Grant Option Does Not Exist" (Doc ID 1628033.1)

How to switch RUN File System and Patch File System in R12.2

The existence of the dual file system has implications for patches that change the system configuration. Depending on the specific situation, configuration changes can be made to either the run file system or the patch file system.

Sourcing Environment for run File system:

. /u01/app/EBSapps.env RUN

Sourcing Environment for patch File system:

. /u01/app/EBSapps.env patch
  


How to Synchronize FND_NODES, ADOP_VALID_NODES, and FND_OAM_CONTEXT_FILES in 12.2 When ADOP Phase=Prepare Fails with Error

[STATEMENT] Please run adopscanlog utility, using the command

"adopscanlog -latest=yes"

to get the list of the log files along with snippet of the error message corresponding to each log file.

Cause
There is a synchronization error between fnd_nodes, adop_valid_nodes, and fnd_oam_context_files.

Solution
Due to the method required for "cleaning out" / "re-synchronizing" the following tables, it is EXPECTED / REQUIRED that the Applications have been shutdown.
The only thing running should be the Database Tier.
Note: A full backup should also be taken before any testing begins.

Test the following steps in a development instance, and then migrate accordingly once the desired result is confirmed:

1. Backup the fnd_oam_context_files, fnd_nodes, and adop_valid_nodes tables in the EBS env:

 sqlplus applsys/pwd

 create table fnd_oam_context_files_bkp as select * from fnd_oam_context_files;
create table fnd_nodes_bk as select * from fnd_nodes;
create table adop_valid_nodes_bk as select * from adop_valid_nodes;

2. Truncate the following tables:

truncate table fnd_oam_context_files;
truncate table fnd_nodes;
truncate table adop_valid_nodes;

3. Run AutoConfig on the DB tier
Confirm Autoconfig completes successfully

4. Run Autoconfig on the run file system.
    Source the Environment File to switch to run file system
    . /u01/app/EBSapps.env RUN

Confirm Autoconfig completes successfully

5. Run Autoconfig on the patch file system
   Source the Environment File to switch to patch file system
   . /u01/app/EBSapps.env patch

 Due to the method required for "cleaning out" / "re-synchronizing" the following tables, it is           EXPECTED / REQUIRED that the Applications have been shutdown.
 The only thing running should be the Database Tier.
 Before running Autoconfig on the patch file system the ebs_login trigger MUST be disabled
 After the successful completion of Autoconfig the ebs_login trigger MUST be re-enabled.
 This needs to be done as the SYSTEM schema user.
   a. Disable the ebs_login trigger using the following SQL.
     SQL> alter trigger ebs_logon disable;
  At this time Run autoconfig with the patch env sourced.
  Make sure Autoconfig completes ok
   b. Enable the ebs_login trigger using the following SQL.
  SQL> alter trigger ebs_logon enable;

6. After Autoconfig has been run successfully on all nodes, run the following two (2) queries in order to verify the tables have been correctly populated:
SQL> select node_id, platform_code, support_db D, support_cp C, support_admin A,
support_forms F, support_web W, node_name, server_id, server_address, domain, webhost, virtual_ip, status from fnd_nodes order by node_id;

SQL> select NAME,VERSION,PATH, STATUS from FND_OAM_CONTEXT_FILES;

Check adop with prepare phase. This time it should complete successfully.
$ adop phase=prepare

The prepare phase completed successfully.
adop exiting with status = 0 (Success)
