Drop SQL Profile

Step-1: Check below SQL Profile: SYS_SQLPROF_7cd65e0000

SQL> select name from dba_sql_profiles;


SQL> select NAME,CATEGORY,TYPE,STATUS,TASK_ID,TASK_EXEC_NAME from dba_sql_profiles where NAME like '%7cd65e0000%';


Step-2: Drop below SQL Profile: SYS_SQLPROF_7cd65e0000

SQL> exec dbms_sqltune.drop_sql_profile('SYS_SQLPROF_7cd65e0000');


SQL> select NAME,CATEGORY,TYPE,STATUS,TASK_ID,TASK_EXEC_NAME from dba_sql_profiles where NAME like '%7cd65e0000%';


Drop SQL Plan directives:
==========================

Step-2: Drop SQL Plan directives:

SQL> EXEC DBMS_SPD.flush_sql_plan_directive;

PL/SQL procedure successfully completed.

SQL> BEGIN
FOR rec IN (SELECT directive_id did FROM DBA_SQL_PLAN_DIRECTIVES)
LOOP
DBMS_SPD.DROP_SQL_PLAN_DIRECTIVE (directive_id => rec.did);
END LOOP;
END;   2    3    4    5    6

Step-3:
Set the optimizer_adaptive_features to FALSE. They can Ref. the DOC ID 396009.1 for the recommended parameters for EBS.

Optimizer Parameters


Optimizer Parameters
 
ð  Release 12 uses cost based optimization. The following optimizer  parameters must be set as shown, and should not be changed.
 
ð  It is recommended to disable the adaptive optimizer features: adaptive plans,  automatic re-optimization, and SQL plan directives. 

ð  Post 12.1.0.2.170831 (Aug 2017) Bundle Patch for Windows Platforms or higher

ð  Remove optimizer_adaptive_features from pfile/spfile and replace it with optimizer_adaptive_plans=FALSE  and optimizer_adaptive_statistics=FALSE

ð  For more details Refer MOS Doc ID 1594274.1(Table 1.5 - Footnote 1).

_optimizer_autostats_job=FALSE #MP Turn off automatic statistics.
optimizer_adaptive_features = FALSE #MP 

Parallel Execution and Oracle RAC parameters


Parallel Execution and Oracle RAC parameters

ð  It is recommended to set the parameters PARALLEL_FORCE_LOCAL on each instance, to ensure that parallel requests do not span instances.

ð  As of 11gR2, EBS customers must set the value of this parameter to TRUE and then are no longer required to set parallel_instance_groups and instance groups for the purpose of preventing inter-instance sql parallelism in RAC environments.


parallel_force_local=TRUE


TEMP_UNDO_ENABLED


TEMP_UNDO_ENABLED


ð  TEMP_UNDO_ENABLED helps to reduce the amount of redo caused by DML on global temporary tables.

ð   Setting to TRUE may cause serious issues, such as ORA-55526, for distributed transactions (Ref. Bug 20712819). 

ð  The recommended value for systems using distributed transactions is currently FALSE (Pending ER 24286334). 

ð  If not using distributed transactions, TRUE will improve performance by eliminating REDO on permanent UNDO.


temp_undo_enabled = FALSE


Database Password Case Sensitivity

Database Password Case Sensitivity


ð  The default value of this parameter is TRUE, i.e. passwords are case-sensitive at the database level.

ð  Although the parameter is deprecated in Database 12c, it still needs to be explicitly set for Oracle E-Business Suite.

ð  To enable case-sensitivity of database passwords in Oracle E-Business Suite (supported with Oracle E-Business Suite Release 12.1.1 or higher), set the parameter to TRUE and follow the steps in Doc ID 1581584.1. Also, if on a release prior to Release 12.2,  apply patch 12964564.

ð  To disable case-sensitivity, set the parameter to FALSE.

sec_case_sensitive_logon = FALSE

PGA_AGGREGATE_LIMIT feature in 12c limits PGA memory usage


PGA_AGGREGATE_LIMIT feature in 12c limits PGA memory usage

·         The default value of PGA_AGGREGATE_LIMIT is set to the greater of 2 GB, 200% of PGA_AGGREGATE_TARGET, and 3 MB times the PROCESSES parameter.
·          It will not exceed 120% of the physical memory size minus the total SGA size.



·         PGA_AGGREGATE_LIMIT cannot be set below its default value. If a value of 0 is specified, it means there is no limit to the aggregate PGA memory consumed by the instance.
·         If total PGA memory usage is over PGA_AGGREGATE_LIMIT value. The sessions or processes that are consuming the most untunable PGA memory will be terminated.

·         Recommended value for PGA_AGGREGATE_LIMIT is 0.

·         pga_aggregate_limit = 0

FS_CLONE issues


FS_CLONE issues

Issue 1:

There is not enough space on the volume you have specified.
Oracle Universal Installer has detected that you currently have 0 MB available on the chosen volume. 750 MB of space is required for the software.

Solution:

Rapidwiz File System Upgrade Fails With "There is not enough space on the volume you have specified." Even Though There Is Sufficient Space (Doc ID 1942808.1)

ð   As per note id, we have requested SA team to reduce the mount point((/test/applmgr) size from 4TB to 2TB

Issue 2:

ERROR: RC-50410: Fatal: OUI Registration failed with an Abnormal Termination error during call from ouicli.pl.

Solution:

Fs_Clone fails with "ERROR: RC-50410: Fatal: OUI Registration failed with an Abnormal Termination error" (Doc ID 2095966.1)

ð  As per node id, we have unset the $ENV


Issue 3:

[UNEXPECTED]Error 1 occurred during Blocking ports on hostname01
[UNEXPECTED]Error 1 occurred during Blocking ports on hostname02

Patch filesystem services were running on hostname01 and hostname02

Solution:

ð   Issue got resolved after clearing the services related to patch filesystem(fs1).

REP-3000: Internal error starting Oracle Toolkit.


Error Message:

REP-3000: Internal error starting Oracle Toolkit.


We have noticed that Active Users program is failing with above error message.
Only report related programs are failing (like Active Users) all other programs are completing normal.

We suspected that this is due to DISPLAY/VNC session issue.

When we checked CONTEXT_FILE the DISPLAY setting was set to "hostname:1"

Solution:

DISPALY setting is set to hostname:1, So we need to start the vnc session with port 1.


Xlib: connection to "hostname:1.0" refused by server
Xlib: No protocol specified

Xlib: connection to "znohsvtvc513:1.0" refused by server
Xlib: No protocol specified

I have encountered  above issue when i started vnc session with my GUID.

After some time i realized that it should be started from "applmgr" user.

After starting vncserver :1 as "applmgr" user issue got resolved.
