The work of the Disqualification of Linux Shell Script

• ESXi 4.0 underperformance (one quarter) of the workload on Linux (shell scripting) - specific example given

  Hi everyone;

  Basics:

  Our vmware environment is vmware esxi 4.0 on an IBM x 3650, double quad-core processors, 32 GB RAM, 6 x 450 GB 15 k RPM WHAT drives (local). There is a single guest from vmware that is inactive except for this test. The guest is a RHEL 5.3 x86_64 only fully patched host. Best practice: current version of vmware tools is installed, vmxnet3 driver is used, the kernel startup params are notsc divisor = 10, all 6 discs are in a raid10 table, elevator is set to noop.

  The above, vmware environment with regard to performance, is facing a 5 year, IBM x 336, who has a copy of RHEL installed.

  Scenario:

  We have shell scripts which runs a software installation rather complicated. Without getting too inside, scripts to make a ton of calls of subroutines (e.g. VAR = $(écho $line | cut-f1-d:)). This script works horribly slow in the new vmware and vmware environment otherwise slow (less than 1/2 the speed, perhaps only 1/3 the speed) 5 year old physical server. Because the operation is an operation of 15 minutes in the best of times, it takes 30-60 minutes to complete, on a new server.

  As a test case, I made this script (yes I know 'let i = i + 1' would be faster, but do not reflect the actual workload.)

  #! / bin/sh

  I have = 0

  While------[$i - lt 1000]

  do

  I have = $(echo "$i + 1" | bc)

  fact

  I then run this script (which basically incriments I from 0 to 1000) and time. I the time using an external timer because I know that vmware can distort a bit sometimes. However, the results represent the picture. The script above takes about 8.5 seconds on the guest operating system and about 2.25 seconds on the physical host computer. Basically, it is considerably slower.

  I have read the 3 VI and vSphere 4 practices better performance... I read that potentially binary translation and VMware could cause a problem, or the fork then the/bin/sh is slow on vmware (some article strange re Zap?) ... but I'm curious to know if anyone has had similar experiences or recommendations? For the guys out there linux, RHEL and other suppliers, the above script gives also a second 8-10 response?

  For the people of vmware, y at - it something on bash (/ bin/sh) which makes it slow... especially on iterations () $ who call/bin/sh and more? I tried to replace the above $i = with 'I = i + 1' and it ends in less than a second and I tried to add a true/bin/in the mixture of execution, and he had a minimal impact on the speed (currently testing the forkO / exit() combo - and re - write this particular program/script I know is an option, do not write say to do)

  Any comments welcome, thank you

  MMU operations-hungry as fork/exec run a lot faster on processors AMD with IVR, that we support with ESX 3.5 and Intel processors with EFA, requiring vSphere.

• Run the emca in linux shell script command

  Hello everyone,
  I would like to launch emca to create dbconsole in my Production database, so I have to run this command in the script, because this command causes the base of data either in passive mode.
  my gaze of script like:
  #/ bin/sh
  Su - oraprod-c"sh /oraprod/db/tech_st/10.2.0/bin/emca - config dbcontrol db-rest create" > > /backora/log.log "
  
  but the problem is how to interact with this command (provide the parameters of database SID, Port of the database, sys password...)

  And the MAIL_SERVER_NAME too. But using "" can do the trick.

• Stop the Service Console and shell scripts

  Now that VMware announced ESX 4.1 is their last hypervisor with a service console, I was wondering-

  What are the options to make what is now a large number of Linux shell scripts perform the same functions on ESXi - i.e. PowerCLI, Host Profiles, etc. and how long we have until officially support chips for the ESX service console?

  Thank you

  PowerCLI does not rely on a service console. However, you must have paid the ESXi version for them to work.  With respect to the profiles of the host, which is a characteristic of vCenter and has more no dependencies on the COS.  You can start watching to convert all of your shell scripts PowerCLI and use scripts.

  What about when VMware will stop support for ESX, I do not anticipate happening any time soon.

• The BCC ETPM Linux database scripts?

  I recently worked with BCC and ETPM on Linux platforms and the only linux script, I found the cdxdba.plx allows to create the database. I was wondering if there is a Linux version of Windows database scripts to export/upgrade/etc. tasks

  I've used this successfully:

  -Source operations
  Log on as oracle
  (Make sure your ora env is set with the associated database)
  Export NLS_LANG = AMERICAN_AMERICA. AL32UTF8
  expdp DUMPFILE DUMP_DIR = DIRECTORY = expdp_CISADM_ (mydb) _ (today) .dmp LOGFILE = expdp.log patterns = EXCLUDE = STATISTICS CISADM
  (enter the credentials of the manager/system)

  -Target operations
  Log on as oracle
  (Make sure your ora env is set with the associated database)
  Export NLS_LANG = AMERICAN_AMERICA. AL32UTF8
  Impdp DIRECTORY = DUMPFILE DUMP_DIR = expdp_CISADM_ (mydb) _ (today) .dmp LOGFILE = impdp.log patterns = CISADM
  (enter the credentials of the manager/system)

• PowerShell to execute the shell script in Linux guest

  Is there a way of powershell to access a Linux VM in a domain environment and then run a Linux shell script to a guest Linux OS - for example to set the network settings of the virtual machine?

  Thank you!

  You can use the Invoke-VMScript cmdlet. It allows you to run a script bash inside the Linux guests supported.

  There is also the Set-VMGuestNetworkInterface cmdlet to configure NETWORK card. It is based in fact on the same technique as the Invoke-VMScript cmdlet, but PowerCLI Dev team provided the bash script to you.

• Call the OBIEE Unix Shell Script

  Hi all
  
  Is it possible to make a call to a Unix Shell Script with the framework of the Action of OBIEE.
  
  Thanks in advance

  I don't think, but we can go for it instead side BI. Try to transfer the same features side shell script so that the script can identify your report using the tail of the log nqquery and execute the rest of your lines in shell script.

  This can done and works as expected. If you identify your report instead of this long logical query at all with my suggestion that you can go for a little keyword.

• Executes the DDL statement via ksh script

  I need execute a DDL statement (for example, ALTER USER) using ksh script and capture the result to be able to verify whether the statement succeeded or failed.

  I wrote a script below:

  SQL = "test ALTER USER...;"

  When I run the above script, I get 'modified by the user.  Commit complete. "written in a file.

  Is there an easy way to check the contents of the file for the result to a variable instead of an output file or program to see if the ALTER USER statement was successful?

  There is no need to check the contents of the file, just check for the error in your shell script.  Something like:

  Oracle > cat t.sh
  Export ORALCE_SID = dev2
  SQL = "select 1/0 from dual;"
  sqlplus-s / t.log

• Try to collect events to a log file and the Agent installed Linux and work - need help.

  I modified liagent.ini by documentation... If I understand well it... actually I changed so many times my eyes hurt.

  Here it is:

  ; Configuration of the Agent of VMware Log Insight. Please save it in UTF-8 format if you use non-ASCII names / values!

  ; The actual configuration is this file that is associated with the server settings to form animal - effective .ini

  ; Note: The agent is not necessary to restart after making a configuration change

  ; Note: It may be more efficient to configure Server Agents page!

  [Server]

  hostname = 192.168.88.89

  ; Name of host or IP of your Server Log Insight / load balancing cluster. By default:

  ; hostname = LOGINSIGHT

  ; Protocol can be cfapi (Log Insight REST API), syslog. By default:

  proto = cfapi

  ; Server port connect Insight to connect to you. Default ports for protocols (TCP all):

  ; syslog: 514; syslog with ssl: 6514; cfapi: 9000; cfapi with ssl: 9543. By default:

  port = 9000

  ; Use SSL. By default:

  SSL = no.

  ; Example of configuration with the certification authority:

  ; SSL = yes

  ; ssl_ca_path=/etc/PKI/TLS/certs/CA.PEM

  ; Time in minutes to force the reconnection to the server.

  ; This option reduces the imbalances caused by the long lifetime as TCP connections. By default:

  Reconnect = 30

  [record]

  ; Logging detail level: 0 (no debug messages), 1 (essentials), 2 (verbose with more impact on performance).

  ; This option should always be 0 in normal conditions. By default:

  debug_level = 1

  Post edited by: kevinkeeneyjr added liagent.ini

  Ah! Yes, the agent is to collect real-time events. If no new event is written then it won't work. If you want to collect logs that have been generated before you use the importer of Log insight which was published with LI 3.3. I hope this helps!

• Fail to perform the work of the Disqualification of command line

  Hi all experts,

  I am facing problem on execution of OEDQ work of prompt on localhost.

  My system configuration is:

  OS-> Windows 7

  RAM-> 2 GB

  System-> 32-bit type

  On my system, OEDQ 11.1.1.7.3. (1050) is installed in the path C:\Program Files\Datanomic\dnDirector

  The jmxtools.jar file is present in the path C:\Program Files\Datanomic\dnDirector\tools

  At first, I opened the windows command prompt. Go to the above specified jmxtools.jar directory on command prompt.

  Then after one in a single command according to the document of the Disqualification command-line tool.

  1. Java -jmxtools.jar jar version / / work on my system
  2. Java -jar jmxtools.jar - list / / also work on my system
  3. java-jar jmxtools.jar runjob-doingTest of the employment project-Disqualification - CDS - u dnadmin Pei p4dqnvo2 localhost:9002 / / does not work on my system

  where,

  doingTest-> name of the job that has been created by me

  Disqualification - CD-> name of the project (in fact, it is built into the project on OEDQ)

  dnadmin-> user name

  p4dqnvo2-> password

  localhost-> name of the server on which OEDQ has been installed (but I mostly doubt here, is good?)

  9002 > port number

  After that, run it above command shows below error:

  Error in levant interface system to remote registry: error during JRMP connection on putting in place;

  nested exception is: java.io.EOFException (code: 7052)

  I think that it is related to my system, network error.  I tried Googling several times to find the solution to this problem. but, alas!  I am powerless to solve this problem.

  Please someone help me on this problem.

  Any help will be much appreciated.  Thanks adavance.

  Kind regards

  Hello

  Looks like you have the wrong port. You need the JMX port, which is probably in your configuration, 9005, not the HTTP port (9002).

  You did not first louyo 'NAT or Bridged?' question but its context was not perhaps not clear even if, after seeing...

  [root@test-host ~] # ifconfig

  eth0 Link encap HWaddr 00: 0C: 29:55:EF:96

  INET addr:192.168.241.0 Bcast:192.168.241.255 mask: 255.255.255.0

  RUNNING BROADCAST MULTICAST MTU:1500 metric: 1

  It is not really important because despite everything, it is patently obvious what is the main problem!

  The IP address of the guest operating system is not set properly!

  louyo asked 'NAT or Bridged?', meaning is card virtual machine network configured as a 'NAT or Bridged?' if it has been filled, the guest operating system would have an IP address on the 192.168.0.0 subnet IP and as NAT would have an IP address on the 192.168.62.0 IP subnet.

  Configure the guest operating system to use DHCP or manually assign a correct IP address while setting the virtual machine Network Adapter is connected by a bridge or a NAT.  Since the host uses a Wi - Fi connection, I suggest using NAT and if manually assign an IP address must be between 192.168.62.3 and 192.168.62.127, as that is beyond the scope of the DHCP Server VMnet8 IP address Pool.  If you choose to use Bridged can use DHCP in the guest operating system or using an IP address that is outside the scope of the routers IP DHCP Server Address Pool and for that, you need to check the Configuration of the router.

  You didn't say which VMware product or version you are using however I strongly suggest you read the documentation and specifically Chapter 5 "Configuring network connections" in Using VMware Workstation (PDF file).

• How to strengthen the failure on jobs of the Disqualification

  We execute the Disqualification autosys scheduler jobs (ksh shell script called CLI command) and have the following conditions:

  1. do not the autosys job each time that there is a problem in the execution of the task of the Disqualification (i.e. the Disqualification job failed because of blocking problem)

  2. do not work autosys whenever at least a save fails in the processor business rules

  Currently, the shell script returns a 0 return code (success) on both scenarios.

  Can you advice how Disqualification jobs can be configured to trigger failure to the caller?

  Yes the bug has been checked on 12.2.1. It is the version, and not specific o/s. The bug does not exist in previous versions. We are working on a fix for the fix.

• Problems with the developer of the Disqualification VM

  We want to assess a few characteristics of the Disqualification, so the developer provided by Oracle VM for 12.1.3 was downloaded and imported in Virtual Box and configured by the installation guide for VM to Oracle for the Disqualification.  He promises (I guess you are aware) a ready-to-go, essentially free installation, vm where some exercises based on a Disqualification can be worked, etc.

  It will not work.  We are not an Oracle shop in a perspective of DB, aren't we a store of Linux so there is not a lot of expertise to try to solve the problems with what is supposed to be a good install.

  Essentially, the WebLogic administration server fails to start and the Disqualification app server does not start.

  Don't want to take much time at all, but I'm just curious, if there are a few known issues with this VM developer who are documented somewhere and resolution so that we can get things facing up and running without having to learn about weblogic, etc at this stage.

  Thanks in advance.

  There there was no problems known with this, other than to ensure that you have sufficient resources to run it. A machine at least 16 GB of RAM is preferred.

  An alternative to evaluation purposes would be the quick start installation for windows you will find on the page of the OTN Disqualification.

• Using the shell script sql variable

  OS: Oracle Linux 5.10

  DB Oracle 11.2.0

  I have need to query the database and assign the return value to a variable of shell, but it does not work.

  create table imr_env (key varchar2(1000), value varchar2(1000) ;
  insert into imr_env values('TblspcUsagePct','90');
  commit;
  

  Here is the shell script:

  #!/bin/bash
  echo "in script"
  ORACLE_HOME=/u01/app/oracle/product/11.2.0/db_1 ; export ORACLE_HOME
  ORACLE_SID=IMR1 ; export ORACLE_SID
  export PATH=$PATH:$ORACLE_HOME/bin
  
  pct=`sqlplus -S app/manager <<END
         set serveroutput on
         declare
            output_val number ;

            select value into output_val from imr_env where key = 'TblspcUsagePct' ;
            dbms_output.put_line('output_val: ' || to_char(output_val)) ;

  ## another sqlplus connection, use $pct in the where clause
  
  echo "var value is $pct"
  
  

  Here is the result:

  SQL> ./test.sh
  in script
  var value is 
  
  output_val: 90
  

  Why isn't the shell variable is populated with the value retrieved from the database?

  I need to use $pct in another query that will be storage spaces that are at least 90% full.

  I had to change to a korn shell - I couldn't get the "READ" command in shell or bash.

  But it is not only "READ" command:

  SQL > select * from IMR_ENV;
