Migrating Backed-Up Logical Logs to Tape

You can set up your storage manager to back up logical logs to disk and then write a script to automatically migrate the logical logs from disk to tape for off-site storage. Edit the onbar script to call this migration script after the onbar_d process completes. The following example shows a script that calls the migration script:

UNIX Only

onbar_d "$@" # starts the backup or restore
EXIT_CODE=$?         # any errors?

PHYS_ONLY=false      #if it's physical-only, do nothing
for OPTION in $*; do
    if [$OPTION = -p]; then
        PHYS_ONLY = true

    fi
done
if ! PHYS_ONLY; then   # if logs were backed up, call another
     migrate_logs      # program to move them to tape
fi

End of UNIX Only

Windows Only

This example for Windows invokes the migration script:

%INFORMIXDIR%\bin\onbar_d %*
set onbar_d_return=%errorlevel%

if "%onbar_d_return%" == "0" goto backupcom
goto skip

REM Check if the command is a backup command

:backupcom
if "%1" == "-b" goto m_log
if "%1" == "-l" goto m_log
goto skip

REM Invoke the user-defined program to migrate the logs

:m_log
migrate_log

REM Set the return code from onbar_d (this must be on the last 
line of the script)

:skip
%INFORMIXDIR%\bin\set_error %onbar_d_return%

:end
