Recovery LOG Script

Question

Hi we have copied our PRD system into a new box.
The new system is not a standby system of the PRD system, just a copy.
We have build a script that sends logbackups to tape and to this new system for recovery.
Is there a way to recover the log on the copied system with a script without user interaction?
I have tried this but no sucess
dbmcli -d PRD -u superdba,******* recover_start Autologbackup LOG
-24991,ERR_NODBSESSION: no database session available
Any help?

To make a more complete and automated Windows script, I have made some amendments so as it will generate a recovery file, using the logs it needs to get up to the last avilable log file page number, compared to its current log page number, and apply it, each time it is run, and then shut the db back down ready to be put back to admin mode for more log applications at a later point. It also looks at the live host to find out what backup page it is up to.
This needs to be run as a batch file rather than from the command line, due to the difference in the way windows interprets the %% variables between the two modes.
This can then be scheduled to run at set times and keeps the standby up to date. The script is in three sections, which gets around the issue of it trying to import the recovery script before it has finished.
The scripts need to be saved separately, and called from the central batch file on the standby server.
To adapt this script the database name needs changing from CSP, password needs setting where xxxx is present after SUPERDBA. Also the LiveDB variable needs setting to the FQDN of the live host server i.e. ADCB-EF-1.domain. Obviously if the locations of you dbmcli.exe and things are different they need to be amended also.
The command which searches for the logs (`"dir E:\Backup\CSP\Log\Auto\au. /b /o:e"`) would need to have the File\Device path for the log backup and the first couple of letters of the file name as would the name of the defined backup medium, in this case Auto_Log_Backup
