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.

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 !!
