Duplicate an existing server environment

The following describes how to duplicate an existing MOMI environment making the changes necessary in order to support another instance of the MOMI server. Take note of the explanations following as avoiding some files may speed up the creation of the duplicate environment.

1. stop the existing MOMI process.

2. using FUP duplicate all of the files in the existing MOMI subvolume to another subvolume.

3. restart the existing MOMI process.

4. In the duplicate OBYMOMI file, assign a new process name to MOMI (each main MOMI must have a unique name).

5. In the duplicate CONFMOMI file, change the settings that must be unique for each environment:

for the keyword TCPIP-LISTEN, assign a new port number (each MOMI server must listen on a unique port).

for the keyword HSTnnDB, assign new vol/subvol locations (each MOMI server must have unique history files).

check the file for any other reference to vol/subvol used by the existing MOMI for storage or work purposes (the keywords previously listed are the most common but a few others exist).

The following are brief explanations of certain files within the MOMI subvolume. MOMI will automatically create on start up new one(s) if they are not duplicated into the new environment:

The CNF01DB file is the MOMI configuration database. It stores configuration information entered online such as Alarm definitions. It does not generally store information found in the OBYMOMI or CONFMOMI files. To start the start the duplicate environment 'clean', simply delete this file.

The LOG01DB file is the MOMI log file. It stores messages logged by MOMI. If you want to start the duplicate environment with an empty log file, simply delete this file.

The HSTnnDB files are the MOMI history files. If you want to start the duplicate environment with empty history files, simply delete them. These files are usually large and may take some time to duplicate. It is usually faster to duplicate them from one disk volume to another (to avoid drive thrashing).
