The overall function of the CM Operations Manager is to transfer configuration data between planning tools, NetAct Configurator, and the network. It provides both real-time feedback and history information on the operations.

CM Operations Manager functionality includes the following operations: Provisioning plans to the network:
Preparing, pre-activating, activating Validating BSC
Queuing for RNC provisioning and BSC file-based provisioning Scheduling provisioning operations
Generating and activating backup plans Falling back the RNC database

3G Rehosting Wizard
3G Rehosting Wizard is a functionality included in the Rehosting WCDMA BTS Sites tool, which facilitates and speeds up the execution of the WCDMA BTS sites rehosting operations. It enables faster rehosting preparation by minimising the number of param- eters to be entered. The 3G Rehosting Wizard guides you step by step through the defining rehosting parameters process for each BTS site to be re-hosted. For each BTS site you need to specify only the parameters that are changing during the rehosting process. You can change the default set of the rehosting parameters to be specified and their names shown in the user interface by defining your own Rehosting Wizard XML file. 3G Rehosting Wizard starts automatically when you drag and drop or copy and paste the WBTS(s) to be re-hosted from the CM Editor to the Rehosting dialog in the CM Oper- ations Manager.

Workflow engine
Workflow is a configurable workspace, executed from CM Operations Manager, where operator-specific tasks can be defined and executed in a user-friendly manner. Workflow engine controls the operation execution and takes care of the operation feed- back. The purpose of workflow engine is to simplify and speed up the execution of pro- cesses which consist of number of operations, for example, export, import, download, upload, provisioning, and automated plan generation.
Nokia Siemens Networks provides the following ready-made operation workflows: Reconfiguring Transport for IP-based Iub
Depending on the workflow execution, you can select the appropriate network elements to which you want to apply desired workflow.
The workflow definition contains a list of operations to be executed to complete a task. You can execute each operation defined in the selected workflow separately. After exe- cuting each operation, you can monitor its progress, and when it is completed, you can see the feedback of the operation.
Apart from the ready-made operation workflows provided by Nokia Siemens Networks, you can create/define new workflows tailored for your specific needs. The workflow is created as an XML-formatted operation definition list file.
For more information on workflow engine, see CM Operations Manager Help.

Command Manager window
Command Manager window in CM Operations Manager provides a convenient and fast way to execute commands to MSC, MGW, SGSN, GGSN ang FING. It allows you to perform the following operations:
The output of the executed command or command file can be viewed in the Command Manager window and exported to a file.
The user can also schedule the command execution to be performed at a specified time. Command Manager allows to manage network elements as a user defined groups for faster command execution on several network elements at one time. There is also pos- sibility to execute command at once on more than one group at one time.

Operation statuses in CM Operations Manager
CM Operations Manager provides the information on the statuses of the operations and operation groups that the user has executed using CM Operations Manager. The oper- ation group is, for example, plan provisioning, while the operation is a plan provision to a specific network element (e.g. BSC). It means that operation group consist of number
operation groups are visible in the Operation History tab of the CM Operations Manager user interface.
The following operation (or operation group) statuses are possible:
Started - RAC Operation Service has created a new operation (and group) to the NetAct Database.
Ongoing - The operation execution has been started.
Finished - The operation has been completed without errors. The possible warnings can be checked from operation feedback.
Failed - The operation has failed. The reasons for the failure are described in oper- ation feedback.
Interrupted - The user has interrupted the operation, which has been in Started or Ongoing state.
Interrupting (only for operation group) - The user has interrupted the operation group, but operations which cannot be interrupted will be executed normally and will go to Finished or Failed state.
Queuing - The operation has been put to a queue.
The operation or operation group status is updated to the CM Operations Manager user interface every time the operation status changes. The status information is also saved to the NetAct Database.
