We are, to both our benefit and disadvantage, creatures of habit. We tend to get stuck in our ways quite easily, and it takes a lot of work to change them. And we often don’t realize that these behaviors are getting in our own way when it comes to things like achieving our biggest goals.
Success is quite a unanimously shared goal because we all want to be happy, secure, proud, and respected. But the path there is often loaded with hurdles. There are surely more than enough obstacles posed by the outside world, and you aren’t doing yourself any favors by getting in your own way, so click through to see all the things you should leave behind to propel yourself forward.
A singular idea of success
If you let other people define what success is, you’ll only be chasing after what they have. Instead, consider that some artists define success as completing and releasing their work, as opposed to it selling well. Some define success as being able to do what they love, and others want to hit a certain salary or see an idea through. Define what success means to you first and foremost.
An unhealthy lifestyle
Almost everything you want to achieve in life will depend on your health. Eat well and exercise, and you’ll have the right foundation to chase your dreams.
Downplaying yourself
Being humble is a wonderful quality that we should all maintain, but downplaying yourself so that others will feel better about themselves or because you’re afraid of seeming arrogant is definitely something you want to leave behind.
Mindless scrolling
This is a difficult one because social media apps are literally designed to keep you on them, mindlessly scrolling through an infinite feed, but they’re a huge time suck and they are completely demotivating, as so much of it relies on people showing off and comparing themselves to others.
Short-term thinking
Success involves having a vision and setting long-term goals. Short-term thinking can help start to establish successful habits, but, for example, if you only work out for the summer, it’s not sustainable in comparison to if you were working out because that’s part of who you are.
Excuses
There will always be a reason getting in the way of your success, but in order to achieve success it’s essential to take responsibility for all of your actions, despite the hand that life deals you.
Excuses
There will always be a reason getting in the way of your success, but in order to achieve success it’s essential to take responsibility for all of your actions, despite the hand that life deals you.
A fixed mindset
If the path you’re on isn’t leading you where you want to go, you have to be able to reroute. That could involve learning new skills or trying new methods.
The need for control
It’s important to make plans for the future, but it’s equally as important to allow room for life to happen—and to be prepared so that you’re ready to change your plans. Focusing on what you can actually control will save you a lot of energy.
The dream of overnight success
Even the people who seem to have overnight success were likely working towards their goals out of the spotlight for ages before making it. Just focus on the work you need to do, and a much more sturdy success will come when it’s time.
Waiting for success to feel happy
Success is a moving target, and so if you believe your happiness will only arrive when you achieve success, you’ll be unhappy for a long time. Focus on enjoying the journey and you won’t be so let down when the happiness you get from success inevitably fades or underwhelms you.
Perfectionism
The thing with perfectionism is that it isn’t attainable, so while sometimes it feels like you’re chasing success, you’re actually just running in the same spot. Don’t let perfectionism hold you back from getting yourself and your work out into the world.
Fear of failure or rejection
No one wants to fail, but it’s an inevitable part of everyone’s journey. It’s how you learn, and it’s why you must be resilient. We love to hear a good underdog story, but we’ll have to learn to live it!
Multitasking
This might sound like the opposite of what one might expect, but while multitasking can get a lot done, it also dilutes your efforts. Most successful people know the value in sticking to an idea, project, or task, and being fully present and committed to it.
Other people’s expectations
When we try to meet other people’s expectations, we set ourselves further back on our own unique paths to our own unique ideas of success. Seek to exceed others’ expectations by defying them completely.
The need to be liked
Wouldn’t it be nice if everyone adored you and believed in you? Unfortunately we don’t quite live in such utopia, and everyone has their own acquired taste. That’s totally natural and should actually encourage you to be as authentic as possible because you don’t need to appeal to the masses.
The have-do-be paradigm
Most people think they must have something (i.e. success) before they do something (write a book, start a business, etc.), which will allow them to be something (i.e. happy). But it should be reversed: first be something (happy), then do something from that healthy state, and then you’ll have the things you want (success).
Toxic people
Not only do they totally sap your energy, but they’ll want to hold you back from achieving your goals, sometimes because that’s easier than going after their own. You should surround yourself with people who are more successful than you.
Saying “yes” to everything
You have to be very selective with what you put on your plate if you truly want to achieve your goals. Most successful people say “no” to many tasks and activities from colleagues and even friends and family if they don’t align with their goals.
Competition with peers
We often strive for our goals under the myth that there is a limited amount of success available and we must compete with everyone else on the path, but that’s not actually true. This harmful capitalist-fed competition becomes a battle of who can slightly outdo the other for cheaper and cheaper until neither party is winning.
Copying others
The way to get ahead is really to be authentic, unique, and niche, to provide something novel that you can be an expert in and that shifts the focus away from competition and towards genuine quality work.
Fear of criticism
The sooner you embrace criticism, the sooner you’ll get to where you want to be. Praise, while it feels good, isn’t very constructive, whereas criticism is like free advice. Plus, when it’s not constructive, you’ll know that you’ve achieved enough success to have haters, which means you’re intimidating enough to evoke a response.
Bingeing shows every weekend
When you work hard all week, it can be easy to convince yourself that you “deserve” a weekend of escape into your favorite series. While it’s, of course, essential to take breaks, think of it this way: you deserve to have healthy restful habits that also contribute to your success.
Not valuing what you have now
Of course success depends upon wanting more, but knowing that what you have right now is enough will ensure that you’re acting out of a stable sense of self, and that when you do acquire more you won’t succumb to the endless suffering of always wanting more.
Compartmentalizing your life
Though our lives can feel more and more robotic these days, humans are intrinsically holistic beings that need all parts of life to be aligned so as to really succeed. Don’t neglect one part, like relationships for example, in favor of a career, because you’ll inevitably find that it will seep into your work and throw the balance off.
Self-doubt
Believing that something is too hard for you to achieve is putting a huge hurdle in front of yourself for no reason, giving you a disadvantage just for lack of an optimistic imagination. Plus, if you don’t believe in yourself, how will you get others to?
Seeking permission
You can’t wait for someone to give you permission to chase your dreams, because it won’t ever come. You have to give yourself permission to go against the grain and change your circumstances, no matter what people say.
Reluctance to ask for help
No good business is run by just one person. Instead, a good business person knows how to ask for help and when to delegate. Your personal success might seem like an individual task, but success almost necessarily depends on other people.
Waiting
Timing is important, and when it comes to things like selling your project, for example, it’s best not to be too early. But when it comes to starting, the answer is always now. You’re not behind, and it’s never too late.

If weblogic seems to load slow, or connecting to the nodemanager takes 4-5 mins, the issue may be with /dev/urandom
Change
$JAVA_HOME/jre/lib/security/java.securityReplace
securerandom.source=file:/dev/urandom
with
securerandom.source=file:/dev/./urandomNote that the
/./is needed.I know this seems odd, but it fixed the 5 min startup issue that we saw.
I hope this helps.

(Original questions and answers are copy from narayanasetti’s blog)
Q1) What is Weblogic server?A weblogic server is a instance of java process executing in a JVM.
Weblogic server is a software application that runs as a middle tire between back-end database and related applications and browser based thin clients.
Two Type of servers:
1. Administration server:
2. Managed server:Every domain have one and only one admin server.
It is the central point of control for the webLogic domain.
It runs Weblogic admin console.Q3) What is a Managed server?
A domain can have zero or more managed servers.All the applications are hosted in managed servers only.
Admin server stores the master copy of the domain config. Each Managed server stores local copy of domain config.
Managed server contacts the admin server while starting. So, to do any changes, we need to contact Admin server. Admin server will push those changes to Managed servers. We can start the managed server if admin server failed. But we cant do any changes in managed server if admin is failed(Stopped).Q4) What is a Domain?
Logically related group of WebLogic server resources that are managed as a single unit.
It is administrative boundary for all servers, admin server, managed Servers, clusters, applications, services etc.
– Each domain must have its one Admin server.
– Any given admin or managed server or cluster can belong to only one Domain.
– Managed servers in a domain must run same WL server version and Admin server must have same or higher WL server version.Q5) What is a Cluster?
A cluster is a logical group of WebLogic Servers Instances, acting together for high availability and load Balancing.
All the servers in a cluster must be in same domain. All servers in a cluster must be same version level, though they can run on different machines.Q6) What is a Machine in Weblogic server?
A computer that hosts the WL server instances.
Used by node manager to restart a failed managed server.Q7) What is a Node Manager?
-Node manager is a utility or process running on a physical server that enables starting, stopping,suspending or restarting admin and managed server remotely.
-It is not associated with a domain, though can start any server that reside on same physical server.
-it is required if we use Admin console to start servers.There is two types of NM,
1. java-based
2. Script based.Q8)What are the Default port number for admin, node manager and ssl ?
Default multicast address? Multicast range?Default port no for admin :7001
ssl: 7002
node manager: 5556Default multicast address :239.192.0.0
range 224.0.0.0 to 239.255.255.255What is the Domain in Weblogic server?
An Oracle WebLogic Server administration,
Domain is a logically related group of Oracle WebLogic Server resources.
Domains include a special Oracle WebLogic Server instance called the Administration Server, which is the central point from which you configure and manage all resources in the domain.
Usually,you configure a domain to include additional Oracle WebLogic Server instances called managed Servers.Note:
Domain is a logically related group of Oracle WebLogic Server resources that are managed as a single unit.Back up of existing domain
Abhishek Porwal Simple way is to make tar File.
Atchut Ram Gundu Use domain-builder.sh file under wlsserver directory which will create a template..
Kumara Guruparan R You can take a template of the existing domain… Also config. XML can be backed up… Moreover the data on the server is backed up by tsm servers
Gaguturi Kamalbee pack means copy the pack the domain and unpack means paste the domain to multiple server
Mohammad Faisal Zakarneh pack used to ‘pack’ a domain or managed servers only of domain in a template file .. unpack then used to ‘unpack’ the package packed by pack
PACK Process
export PATH=/export/home/wlsuser/bea/weblogic92/common/bin:$PATH
Syntax:
pack -domain=domain -template=template -template_name=“template_name”
[-template_author=“author”][-template_desc=“description”]
[-managed={true|false}][-log=log_file] [-log_priority=log_priority]if it is in the pack command in the path you can give pack.sh from any directory otherwise you need to goto that path.
Examplebash-3.00$ pack.sh -domain=”/export/home/wlsuser/domains/wlscldom”
-template=”/export/home/wlsuser/templates/wlscltemp.jar” -template_name=”WLS
CLUSTER DOMAIN” -log=/export/home/wlsuser/logs/wlscldompack.log -log_priority=INFO
UNPACK Process
To run this we must already run the pack command on a domain which is already existing. The domain template jar must be copied to the destination machine.Syntax:
unpack -template=template -domain=domain [-user_name=username]
[-password=password] [-app_dir=application_directory]
[-java_home=java_home_directory] [-server_start_mode={dev|prod}]
[-log=log_file] [-log_priority=log_priority]Example
bash-3.00$ unpack.sh -template=wlscltemp.jar -domain=domains/wlscldom
-log=wlscldomunpack.log -log_priority=INFO———————————————————————————————————————-
To unpack managed server also it will work in the similar manner. But need to put the
“-managed=true”Example:
pack.sh -managed=true -domain="/home/wluser/domains/WLclsnm/" -template="/home/wluser/templates/WLclsnm.jar" -template_name="WLS CLUSTER DOMAIN" -log=/home/wluser/logs/wlscldompack.log -log_priority=INFO unpack.sh -template=WLclsnm.jar -domain=domains/WLclsnm -log=WLclsnmpack.log -log_priority=INFO
8. If two managed servers is there Same Domain is configured in both servers, but one server is crashed then how can you create a domain with the same configuration?
Pack one domain and unpack it to the new server for the same domain.

After you installed the Oracle 11gR2 on Linux 7 machine, you start the EM console, and can open it from local server web browser (Firefox). But you don’t like it because that’s firefox plus you have to login to server. You believe DB console is an web service, it should be able to be accessed from any device on same network.
But the truth is NO by default. The port number 1158 which used by EM console are blocked by firewall on this Linux 7 box. You have to do following steps to open the port 1158 in order to access EM console from remote machine:
Edit /etc/sysconfig/iptables, add one new line to active port 1158:
[root@ol7 sysconfig]# vi iptables
... ... ... -A INPUT -i lo -j ACCEPT -A INPUT -p tcp -m state --state NEW -m tcp --dport 22 -j ACCEPT -A INPUT -p tcp -m state --state NEW -m tcp --dport 1158 -j ACCEPT -A INPUT -j REJECT --reject-with icmp-host-prohibited -A FORWARD -j REJECT --reject-with icmp-host-prohibited
Restart iptables service:
[root@ol7 sysconfig]# service iptables restart
Now you can use following link to remotely access EM Console from you be loved browser.

Please see following article:
How to create Physical Standby on the same host for testing purposes (Linux + ORACLE 11.2)
Following is my steps:
Standby Database can be reside on same host (with same Oracle software installation) with primary database. For this configuration, you have to give standby database a different DB_NAME and DB_UNIQUE_NAME.
Assumption:
One Oracle Database Software 11.2.0.4 Linux 64bit installation on host ol7.localdomain
Primary instance created and DB_NAME=ORA11G, DB_UNIQUE_NAME=ORA11G[oraadmin@ol7 oracle]$ hostname ol7.localdomain [oraadmin@ol7 oracle]$ env|grep ORACLE ORACLE_UNQNAME=ORA11G ORACLE_SID=ORA11G ORACLE_BASE=/u01/app/oracle ORACLE_HOSTNAME=ol7.localdomain ORACLE_HOME=/u01/app/oracle/product/11.2.0/dbhome_1
Switch force_logging to YES if not enabled yet:
SQL> select force_logging from v$database; FOR --- NO SQL> alter database force logging; Database altered. SQL> select force_logging from v$database; FOR --- YES
Configure the standby redo logs on the primary database with the same size
SQL> select GROUP#, trunc(bytes/1024/1024,3) Mbytes from v$log; GROUP# MBYTES ---------- ---------- 1 50 2 50 3 50 SQL> alter database add standby logfile 2 ('/u01/app/oracle/HA/redolog1/ORA11G/onlinelog/sdyredo1a.log', 3 '/u01/app/oracle/HA/redolog2/ORA11G/onlinelog/sdyredo2a.log', 4 '/u01/app/oracle/HA/redolog3/ORA11G/onlinelog/sdyredo3a.log') size 50M; Database altered. SQL> alter database add standby logfile 2 ('/u01/app/oracle/HA/redolog1/ORA11G/onlinelog/sdyredo1b.log', 3 '/u01/app/oracle/HA/redolog2/ORA11G/onlinelog/sdyredo2b.log', 4 '/u01/app/oracle/HA/redolog3/ORA11G/onlinelog/sdyredo3b.log') size 50M; Database altered. SQL> alter database add standby logfile 2 ('/u01/app/oracle/HA/redolog1/ORA11G/onlinelog/sdyredo1c.log', 3 '/u01/app/oracle/HA/redolog2/ORA11G/onlinelog/sdyredo2c.log', 4 '/u01/app/oracle/HA/redolog3/ORA11G/onlinelog/sdyredo3c.log') size 50M; Database altered.Set LOG_ARCHIVE_CONFIG and LOG_ARCHIVE_FILE_DEST parameters on the primary database:
SQL> select * from v$dataguard_config; DB_UNIQUE_NAME ------------------------------ ORA11G SQL> alter system set log_archive_config='dg_config=(ORA11G,ORA11GSDY)'; System altered. SQL> select * from v$dataguard_config; DB_UNIQUE_NAME ------------------------------ ORA11G ORA11GSD SQL> alter system set log_archive_dest_1='SERVICE=ORA11GSDY 2 VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) 3 DB_UNIQUE_NAME=ORA11GSDY'; System altered. SQL> show parameter log_archive_dest_1 NAME TYPE VALUE ------------------------------------ ----------- ------------------------------ log_archive_dest_1 string SERVICE=ORA11GSD VALID_FOR=(ONLINE_LOGFILES,PRI MARY_ROLE) DB_UNIQUE_NAME=ORA11GSD
revert DB_RECOVERY_FILE_DEST as archive log destination:
SQL> alter system set log_archive_dest_10= 2 'LOCATION=USE_DB_RECOVERY_FILE_DEST'; System altered. SQL> sho parameter log_archive_dest_10 NAME TYPE VALUE ------------------------------------ ----------- ------------------------------ log_archive_dest_10 string LOCATION=USE_DB_RECOVERY_FILE_ DEST
Configure ARCHIVELOG for primary database and enable automatic archiving:
SQL> select log_mode from v$database; LOG_MODE ------------ NOARCHIVELOG SQL> shutdown immediate; Database closed. Database dismounted. ORACLE instance shut down. SQL> startup mount; ORACLE instance started. Total System Global Area 1453092864 bytes Fixed Size 2253304 bytes Variable Size 872418824 bytes Database Buffers 570425344 bytes Redo Buffers 7995392 bytes Database mounted. SQL> alter database archivelog; Database altered. SQL> alter database open; Database altered. SQL> select log_mode from v$database; LOG_MODE ------------ ARCHIVELOG
Perform a whole database backup including archived redo log files using RMAN:
[oraadmin@ol7 schema]$ rman target / Recovery Manager: Release 11.2.0.4.0 - Production on Fri Jun 12 13:47:39 2015 Copyright (c) 1982, 2011, Oracle and/or its affiliates. All rights reserved. connected to target database: ORA11G (DBID=4278207140) RMAN> backup database plus archivelog delete all input; ... ... ... Finished backup at 12-JUN-15 RMAN>
Prepare listener.ora and tnsname.ora for standby database:
$ORACLE_HOME/network/admin/tnsnames.ora
ORA11G = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = ol7.localdomain)(PORT = 1525)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = ORA11G.localdomain) ) ) LISTENER_ORA11G = (ADDRESS = (PROTOCOL = TCP)(HOST = ol7.localdomain)(PORT = 1525)) ORA11GSDY = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = ol7.localdomain)(PORT = 1525)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = ORA11GSDY.localdomain) ) )
$ORACLE_HOME/network/admin/listener.ora
# listener.ora Network Configuration File: /u01/app/oracle/product/11.2.0/dbhome_1/network/admin/listener.ora # Generated by Oracle configuration tools. ADR_BASE_LISTENER_ORA11G = /u01/app/oracle SID_LIST_LISTENER_ORA11G = (SID_LIST = (SID_DESC = (SID_NAME = PLSExtProc) (ORACLE_HOME = /u01/app/oracle/product/11.2.0/dbhome_1) (PROGRAM = extproc) ) (SID_DESC = (ORACLE_HOME = /u01/app/oracle/product/11.2.0/dbhome_1) (SID_NAME = ORA11G) ) (SID_DESC = (ORACLE_HOME = /u01/app/oracle/product/11.2.0/dbhome_1) (SID_NAME = ORA11GSDY) ) ) LISTENER_ORA11G = (DESCRIPTION_LIST = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = ol7.localdomain)(PORT = 1525)) ) )
Create new password file for the Standby database (or copy it from Primary)
[oraadmin@ol7 admin]$ cd $ORACLE_HOME/dbs [oraadmin@ol7 dbs]$ ls hc_ORA11G.dat init.ora lkORA11G orapwORA11G snapcf_ORA11G.f spfileORA11G.ora [oraadmin@ol7 dbs]$ cp orapwORA11G orapwORA11GSDY Create some directories for Standby DB: [oraadmin@ol7 admin]$ cd $ORACLE_BASE/admin [oraadmin@ol7 admin]$ ls ORA11G [oraadmin@ol7 admin]$ mkdir -p ORA11GSDY/adump [oraadmin@ol7 admin]$ cd $ORACLE_BASE/oradata [oraadmin@ol7 oradata]$ ls ORA11G [oraadmin@ol7 oradata]$ mkdir ORA11GSDY [oraadmin@ol7 oradata]$ ls ORA11G ORA11GSDY
From sqlplus on the Primary database perform next statement for initfile creation:
[oraadmin@ol7 dbs]$ cd $ORACLE_HOME/dbs [oraadmin@ol7 dbs]$ ls hc_ORA11G.dat init.ora lkORA11G orapwORA11G orapwORA11GSDY snapcf_ORA11G.f spfileORA11G.ora [oraadmin@ol7 dbs]$ sqlplus / as sysdba SQL> create pfile from spfile; File created.

And configure initORA11GSD.ora like below:
ORA11G.__db_cache_size=503316480 ORA11G.__java_pool_size=16777216 ORA11G.__large_pool_size=33554432 ORA11G.__oracle_base='/u01/app/oracle' ORA11G.__pga_aggregate_target=520093696 ORA11G.__sga_target=939524096 ORA11G.__shared_io_pool_size=117440512 ORA11G.__shared_pool_size=234881024 ORA11G.__streams_pool_size=16777216 *.audit_file_dest='/u01/app/oracle/admin/ORA11GSD/adump' *.audit_trail='db' *.compatible='11.2.0.4.0' *.control_files='/u01/app/oracle/HA/redolog1/ORA11GSD/controlfile/o1_mf_bqjql4mj_.ctl','/u01/app/oracle/HA/redolog2/ORA11GSD/controlfile/o1_mf_bqjql4ts_.ctl','/u01/app/oracle/HA/redolog3/ORA11GSD/controlfile/o1_mf_bqjql52b_.ctl' *.db_block_size=8192 *.db_create_file_dest='/u01/app/oracle/oradata' *.db_create_online_log_dest_1='/u01/app/oracle/HA/redolog1' *.db_create_online_log_dest_2='/u01/app/oracle/HA/redolog2' *.db_create_online_log_dest_3='/u01/app/oracle/HA/redolog3' *.db_domain='localdomain' *.db_name='ORA11GSD' *.db_recovery_file_dest='/u01/app/oracle/HA/fast_recovery_area' *.db_recovery_file_dest_size=5218762752 *.diagnostic_dest='/u01/app/oracle' *.dispatchers='(PROTOCOL=TCP) (SERVICE=ORA11GXDB)' *.local_listener='LISTENER' *.log_archive_config='dg_config=(ORA11G,ORA11GSD)' # *.log_archive_dest_1='SERVICE=ORA11G ASYNC VALID_FOR=(ONLINE_LOGFILE,PRIMARY_ROLE) DB_UNIQUE_NAME=ORA11GSD' *.log_archive_dest_10='LOCATION=USE_DB_RECOVERY_FILE_DEST' *.memory_target=1443889152 *.open_cursors=300 *.processes=150 *.remote_login_passwordfile='EXCLUSIVE' *.undo_tablespace='UNDOTBS1'
Start Standby database using new pfile:
If you get error “ORA-00845: MEMORY_TARGET not supported on this system“, then refer to following this article.
Start Standby database. Please note, you have to start standby database by using pfile, not spfile which hasn’t been created yet:
[oraadmin@ol7 dbs]$ sqlplus sys/oraadmin@ora11gsd as sysdba; SQL> startup nomount pfile='initORA11GSD.ora'
Invoke RMAN to connect target database (Primary DB) and auxiliary database (standby DB):
[oraadmin@ol7 dbs]$ rman target sys/oraadmin@ora11g ausiliary sys/oraadmin@ora11gsd
and run following script dup.sql
run { allocate channel prmy1 type disk; allocate channel prmy2 type disk; allocate channel prmy3 type disk; allocate channel prmy4 type disk; allocate auxiliary channel stby type disk; duplicate target database for standby from active database spfile parameter_value_convert 'ORA11G','ORA11GSD' set db_unique_name='ORA11GSD' set db_file_name_convert='/u01/app/oracle/oradata/ORA11G/','/u01/app/oracle/oradata/ORA11GSD/' set log_file_name_convert='/ORA11G/','/ORA11GSD/' set control_files='/u01/app/oracle/HA/redolog1/ORA11GSD/controlfile/controlfile01.ctl','/u01/app/oracle/HA/redolog2/ORA11GSD/controlfile/controlfile02.ctl','/u01/app/oracle/HA/redolog3/ORA11GSD/controlfile/controlfile03.ctl' set log_archive_max_processes='5' set fal_client='ORA11GSD' set fal_server='ORA11G' set standby_file_management='AUTO' set log_archive_config='dg_config=(ORA11G,ORA11GSD)' set log_archive_dest_1='service=ORA11G valid_for=(ONLINE_LOGFILE,PRIMARY_ROLE) db_unique_name=ORA11GSD'; }If you see following ORA-17628 error:

This may because you didn’t create directory “/u01/app/oracle/HA/redolog1/ORA11GSD/controlfile” (and also redolog2,redolog3 directories) to host control files yet. Create directory, rerun the scripts, error should be gone. Please also note, when you try to re-run this RMAN script to duplicate database, you may need to remove spfile, restart standby database using pfile again, if the spfile already been created and used by standby database by this RMAN script.

Tip 1:
What to do if you missed 32bit package only on 64bit OS?
[root@ol7 ~]# rpm -qa|grep -i libstdc++
libstdc++-devel-4.8.3-9.el7.x86_64
libstdc++-4.8.3-9.el7.i686
compat-libstdc++-33-3.2.3-72.el7.x86_64
libstdc++-4.8.3-9.el7.x86_64
compat-libstdc++-33-3.2.3-72.el7.i686You can see you missed libstdc++-devel-4.8.3-9.el7.i686./n
Here is simply way to do it:[root@ol7 ~]# yum install libstdc++-develdouble hit “tab” button, you will see an “.i686” automatically appended. See? you don’t need to enter full package name and you can get it installed.
Enjoy!
