Start/Stop LISTENER_ES as Oracle User in Oracle Collabsuite 10g

Published on by AdvaitLeave a comment

Introduction

When we install Oracle Collabsuite 10g, we can administer all the services using oracle user (user who has installed Oracle Collabsuite 10g) except one service, which is LISTENER_ES.

LISTENER_ES is a apps side listener which is mainly responsible for bringing up SMTP and IMAP ports. All the ports for apps tier are defined in ORACLE_HOME/network/admin/listener.ora file present on apps side.

We always have to start LISTENER_ES as a root user and we cannot by default start this using oracle user. However, there is a way to enable start/stop using oracle user. This post explains the same.

Follow below steps to enable oracle to start/stop LISTENER_ES

  • Login to OCS host as root user
  • Go to apps tier and Source the environment using .env file
  • Stop the LISTENER_ES as root user using following command

$ORACLE_HOME/bin/tnslsnr LISTENER_ES stop &

  • As a root user run the below commands

cd $ORACLE_HOME/bin
chown root tnslsnr
chmod 6751 tnslsnr

  • Exit and login to OCS host as OH owner, source the instance on apps side using.env file and Start/stop the listener

lsnrctl start LISTENER_ES
lsnrctl stop LISTENER_ES

Hope this helps !!

Increasing Email Quota in Bulk – Oracle Collabsuite 10g

Published on by AdvaitLeave a comment

Introduction:

Some times we get a situation for increasing email quota for users. For example in Oracle Collabsuite 10g we have a default email quota limit of 38M and some times we want to increase or decrease the limit depending on the requirements.

In such situation we can change the global settings for email quota and any new users created will have the email quota that we specified. But what happens to the existing users? Problem is they will have same quota limit which was set at the time of creation.  However we can also change the quota of existing users as well, not just one by one but in bulk.

This post covers changing email quota for new users and existing users.

Changing E-mail quota for New users

Follow below steps for changing quota for new users

  1. Login to Oracle Web Mail client. The user should be domain administrator.
  2. Navigate to Administration tab
  3. Select an installation from the Installation drop-down list.
  4. Select a domain from the Domain drop-down list.
  5. Click Submit.
  6. Modify the following attributes:

*mail Quota (MB)**:  *(We can put 50MB here)

*** Note: 1048576 MB is the maximum quota that can be specified in this field. If you enter 0, a user has unlimited quota.

For more information check – Oracle Collabsuite Documentation

Changing E-mail quota for Existing Users

To change the email quota for existing users we need to make modification to one of the parameters in OID. For that you can get the value of that parameter from OID into an ldif file using ldapsearch and then modify the file and upload again using ldapmodify. Here are the steps

1) Retrieve information from OID using ldapsearch

$ORACLE_HOME/bin/ldapsearch -h <OID_HOST> -p <OID_PORT> -D “cn=orcladmin” -w <PASSWD> -b
“cn=Users,dc=yourdomain,dc=com,cn=um_system,cn=EMailServerContainer,cn=Products,
cn=OracleContext” -s sub “objectclass=*” dn orclmailquota > quota.ldif

Example:

ldapsearch -h ap6019fems -p 389 -D “cn=orcladmin” -w ocs10gadm -b “cn=Users, dc=ap6019fems, dc=us, dc=oracle, dc=com, cn=um_system, cn=EMailServerContainer, cn=Products, cn=OracleContext” -s sub “objectclass=*” dn orclmailquota > quota.ldif

2) Modify quota.ldif created above

In order to update the information about email quota, modify the ldif file created above so that file looks as given below.

dn:
mail=test1@test.yourdomain.com,cn=users,dc=yourdomain,dc=com,cn=um_system,cn=EMailServerContainer,cn=Products,cn=OracleContext
changetype: modify
replace:orclmailquota
orclmailquota: 50000000

dn:
mail=test2@test.us.oracle.com,cn=users,dc=yourdomain,dc=com,cn=um_system,cn=EMailServerContainer,cn=Products,cn=OracleContext
changetype: modify
replace:orclmailquota
orclmailquota: 50000000

dn:
mail=test3@test.us.oracle.com,cn=users,dc=yourdomain,dc=com,cn=um_system,cn=EMailServerContainer,cn=Products,cn=OracleContext
changetype: modify
replace:orclmailquota
orclmailquota: 50000000

where orclmailquota is the value of quota you want to modify. The values is in bytes.

3) load the modified ldif file

$ORACLE_HOME/bin/ldapmodify -h <ldap-host> -p <ldap-port> -D “cn=orcladmin” -w
<orcladmin_password> -f user.ldif

Example:

$ORACLE_HOME/bin/ldapmodify -h ap6019fems -p 389 -D “cn=orcladmin” -w
ocs10gadm -f quota.ldif

Hope this helps !!

Changing Various Passwords in Oracle Collabsuite 10g

Published on by Advait1 Comment

This simple post is to make you aware of the procedure for changing various passwords in Oracle Collabsuite 10g. I am having a project on Oracle Collabsuite 10g and I faced few issues in password management. So I though of putting the same in an organized way so that one can follow the same process.

There are few super user accounts present in Oracle Collabsuite which is used by administrator. Following is the list of accounts.

  1. ias_admin – used for logging into Oracle Collabsuite Server console (both on infra tier and apps tier)
  2. orcladmin super user for OID (Oracle Internet Directory)
  3. orcladmin super user for SSO (Single Sign On)
  4. Sys, System database users

Out of the above list of users, sys and system users are database users and I am sure you are well aware of the fact about changing passwords for these users. I will explain about changing passwords for other users.

Changing ias_admin password

We can use command line tool or server console for changing ias_admin password.

In user command line tool you can use emctl as given below.

-bash-3.00$ which emctl
~/product/ocs10g/apps/bin/emctl

emctl set password <old ias_admin password> <new ias_admin password>
Example:
[ocs10g@ap6059rt bin]$ emctl set password welcome1 ocs10g
Oracle Enterprise Manager 10g Application Server Control Release 10.1.2.0.2
Copyright (c) 1996, 2005 Oracle Corporation.  All rights reserved.

Changed the password on apps side and was able to login as ias_admin using ocs10g password for link http://ap6059rt.us.oracle.com:1810/emd/console

However password for ias_admin on infra is still welcome1. Confirmed.

Before doing the password change, source the environment which means setting following parameters

ORACLE_HOME
TNS_ADMIN=$ORACLE_HOME/network/admin
ORACLE_SID
PATH=$ORACLE_HOME/bin:$PATH
LD_LIBRARY_PATH=$ORACLE_HOME/lib:$LD_LIBRARY_PATH

If you are setting ORACLE_HOME to apps side then emctl command shown above will change the password only on apps side. For infra tier you have to source the .env file on infra side or set ORACLE_HOME to point to infra tier. Once done you need to run emctl command again to change ias_admin password, but this time on infra side.

You can change the password using collabsuite server console using following steps

1) Go to apps side server console http://ap6059rt.us.oracle.com:1810/emd/console

2) Click on preferences and place old password and new password.

3) Click on OK. Password will get changed

Repeat same thing for infra URL http://ap6059rt.us.oracle.com:1156/emd/console

Changing password for orcladmin Super user for OID

  1. Source the env on infra side
  2. Run oidadmin
  3. Connect using orcladmin
  4. click on orcladmin@<hostname>:<port>
  5. Click on System password tab
  6. Enter new password (ocs10g) for orcladmin and click on Apply at the bottom

Changing password for orcladmin super user for SSO

  1. Login to OIDDAS self-service application using orcladmin user
  2. Go to Directory tab
  3. Search for orcladmin
  4. Click on Edit button
  5. Enter password in password field and Confirm Password field
  6. Click submit

You can also change this orcladmin password using oidadmin tool. You can navigate using following

  1. login to oidadmin as orcladmin (super user for OID)
  2. Go to “Entry Management” -> “dc=com” -> “dc=oracle” -> “dc=us” -> “dc=ap6019fems” -> “cn=Users”
  3. (The above navigation is specific to my instance, in you installation the namespace may be different)
  4. Click on “cn=orcladmin”
  5. On right hand side it will show all the attributes for this user. Scroll down to bottom and you will see a field called userpassword
  6. Change the password here and then click on Apply.

Note that this orcladmin password is different then orcladmin super user for OID.

Hope this helps !!
