This chapter covers the common self service operations that need to be performed before setting up DBaaS or MWaaS. It also describes the monitoring operations that can performed on DBaaS or MWaaS. It contains the following sections:
A PaaS Infrastructure Zone is a group of homogeneous resources such as hosts, or other targets. Each resource in a zone represents a location at which a service instance is to be deployed.
Before you enable or setup DBaaS or MWaaS, you must create a PaaS Infrastructure Zone which allows you to define the placement policy constraints for a specified set of targets and the users to whom this zone will be available.
Prerequisites
Before you create a PaaS Infrastructure Zone, you must ensure that the following prerequisites are met:
The EM_CLOUD_ADMINISTRATOR, EM_SSA_ADMINISTRATOR, and EM_SSA_USER roles must have been created.
The Software Library must have been configured.
Note:
To enable Administrators (or users) to access, and leverage an OMS Agent Filesystem Software Library Location, the owner of the Named Credential must ensure that an explicit View privilege is granted to all the Administrators accessing the OMS Agent location. To do so, you can either click Add Grant and add the names of the administrators while creating the Named Credential, or edit an existing Named Credential to grant privileges to other Administrators (or users) by following these steps:From the Setup menu, select Security, then select Named Credentials.
On the Named Credentials page, click Manage Access.
On the Manage Access page, click Add Grant to add a user, or Change Privilege to edit the privileges of an existing user. Click Save.
For example, if you have a Cloud Plug-in installed, and are using the Cloud features offered in Enterprise Manager, then ensure that the CLOUD_ENGINE_USER is also granted view privileges on credentials associated with Software Library. Since the CLOUD_ENGINE_USER is a hidden user account, the owner of the named credential will not be able to grant him View privileges from the Enterprise Manager UI. To handle this situation, (especially on a Windows host where OMS Agent Filesystem is the recommended approach for setting up Software Library) you can run the following EMCLI commands:
emcli login -username=<username -password =<>
emcli grant_privs -name=CLOUD_ENGINE_USER -privileges="GET_CREDENTIAL;CRED_ANME=<>:CRDED_OWNER=<>"
You must log in as a user with EM_CLOUD_ADMINISTRATOR privileges to create a PaaS Infrastructure Zone.
To create a PaaS Infrastructure Zone, follow these steps:
From the Enterprise menu, select Cloud, then select Middleware and Database Home.
From the Middleware and Database Cloud menu, select Create PaaS Infrastructure Zone. The Create PaaS Infrastructure Zone: General page appears.
Enter a name and description for the zone, and specify appropriate values for placement policy constraints based on the resources available to the members. The EM_SSA_ADMINISTRATOR can use these placement policy constraints to set maximum ceilings for any host in the zone. Placement policy values are used during deployment to filter out hosts that are overburdened. You can define the following placement policy constraints for each host:
Maximum CPU Utilization: The average CPU utilization percentage over a specified period.
Maximum Memory Allocation: The average memory allocation over a specified period.
During provisioning, hosts with these constraints will not be considered for provisioning operations. Click Next. The Create PaaS Infrastructure Zone page appears.
Specify the Named Credentials to be used for provisioning all the targets in this zone. Click the + icon to add new named credentials. The credentials you specify must be the same for all the hosts in this zone.
In the Targets region, click Add to add one or more targets to the zone. A target can be a host or an OVM Zone. See Creating a Zone for details.
Click Next. The Create PaaS Infrastructure Zone: Roles page appears.
A PaaS Infrastructure Zone can be made available to a restricted set of users through the use of roles. Click Add to add and select the roles that can access this PaaS Infrastructure Zone.
Click Next. The Create PaaS Infrastructure Zone: Review page appears. Review the details of the zone being created and click Submit to create the zone. You will return to the Database and Cloud Home page.
To edit a PaaS Infrastructure Zone, follow these steps:
From the Enterprise menu, select Cloud, then select Middleware and Database Cloud Home.
Click on the PaaS Infrastructure Zones link in the General region to drill down to the PaaS Infrastructure Zones page.
Select a PaaS Infrastructure Zone from the list and click Edit.
Follow the steps in the wizard to edit the necessary parameters and click Submit to accept the changes.
To delete a PaaS Infrastructure Zone, follow these steps:
From the Enterprise menu, select Cloud, then select Middleware and Database Cloud Home.
Click on the PaaS Infrastructure Zone link to drill down to the PaaS Infrastructure Zones page.
Select a PaaS Infrastructure Zone from the list and click Delete.
A confirmation message is displayed. Click Delete PaaS Infrastructure Zone to delete the zone.
After the SSA_ADMINISTRATOR has completed DBaaS and MWaaS setup and one or more SSA users have submitted requests, a unified view of the DBaaS and MWaaS service types can be seen on the Middleware and Database Cloud Home page. To view the Middleware and Database Cloud Home page, from the Enterprise menu, select Cloud, then select Middleware and Database Cloud.
