Configuring multiple identical Loaders

Steps to configure multiple identical Loaders.

About this task

Typically, you would configure and start more than one loader of a particular type.

The following examples illustrate how to add extra loaders of a particular type. Run commands as user virtuo unless otherwise indicated.

Procedure

Create a loader instance by using default system properties, or by using the properties of an existing loader instance. To create a loader instance by using default properties, first use lcm_admin to check the data source name and version of the loader you want to create:
```
$ lcm_admin –list
Data Source Information
Techpack Name Version DataSource Name Version Technology Vendor
----------------------------------------------------------------------
Ericsson GSM BSS 1.0 Ericsson BSS R10 GSM Ericsson
```

Add a loader instance, by using the loader_admin command, giving an arbitrary name for the instance and the data source name and version from the required technology pack:

$ loader_admin –init –instance ericssconbss_r10_1 –dsname “Ericsson BSS” 
–dsversion R10
Buildfile: /appl/virtuo/conf/loader/loader_admin.xml
init:
[initlog] 18:14:11,483 [main] WARN logging - TRCE-0022 : 
The name of the process is null or empty.
initloader:
[initloader] Initialise Loader:
[initloader] Instance Name: [ericssconbss_r10_1]
[initloader] Datasource Name: [Ericsson BSS]
[initloader] Datasource Version: [R10]
[initloader] New properties created for [ericssconbss_r10_1]
[initloader] Created sap process file for [ericssconbss_r10_1]
[initloader] Restarted sapmgr
[initloader] New instance creation completed

Create an instance from the properties of an existing instance:

$ loader_admin –init –instance ericssconbss_r10_1 -copy ericssonbss_r10
Buildfile: /appl/virtuo/conf/loader/loader_admin.xml
init:
[initlog] 18:17:27,389 [main] WARN logging - TRCE-0022 : 
The name of the process is null or empty.
initloader:
[initloader] Initialise Loader:
[initloader] Instance Name: [ericssconbss_r10_1]
[initloader] Source instance name: [ericssonbss_r10]
[initloader] New properties created for [ericssconbss_r10_1]
[initloader] Created sap process file for [ericssconbss_r10_1]
[initloader] Restarted sapmgr
[initloader] New instance creation completed
BUILD SUCCESSFUL
Total time: 8 seconds

Whichever method you use to create the new loader, use the sap disp command to check that it is now in the SAP process list. (Note SAP might be unavailable for a few seconds after loader_admin –init while the sapmgr process reinitializes):
