Step 2: Porting ISM to Your Target Database Server

To port ISM to your target database server

Log in as user root (UNIX) or Administrator (Windows) on the target database server.
Shut down the Informix database server and ISM.
Dynamic Server
On Dynamic Server:
```
onmode -ky
ism_shutdown
```
End of Dynamic Server

Extended Parallel Server
On Extended Parallel Server:
```
xctl onmode -ky
ism_shutdown
```
End of Extended Parallel Server
Unset the ISM_CLIENT environment variable as follows:
```
unset ISM_CLIENT
```
Edit the ism_startup script or ism_startup.bat script:
UNIX Only
On UNIX:
1. Locate the following line in the $INFORMIXDIR/bin/ism_startup script and type hostname verbatim:
```
hostname=$(hostname)
```
2. Add the following line immediately after that line:
```
hostname=source_hostname
```
End of UNIX Only

Windows Only
On Windows:
1. Locate the following line in the %INFORMIXDIR%\bin\ism_startup.bat script:
```
Set nextLabel = ask_init
```
2. Add the following line immediately before that line:
```
set hostname = source_hostname
```
End of Windows Only
Reinitialize ISM:
```
ism_startup -init
```

Using a text editor, create a temporary file and enter the following information:

UNIX Only

On UNIX:

create type: NSR client; name: source_hostname; remote
access: root@target_hostname, informix@target_hostname

End of UNIX Only

Windows Only

On Windows:

create type: NSR client; name: source_hostname;
remote access: Administrator@target_hostname,
informix@target_hostname

End of Windows Only

Run the following command against the temporary file:
```
nsradmin -s target_hostname -i temporary_file
```

To replicate ISM with the same resources that you have on the source host, you must recover your bootstrap

If your source INFORMIXDIR does not match your target INFORMIXDIR, you need to create a symbolic link to recover the bootstrap from the source computer.
For example, if INFORMIXDIR on your source computer is /usr2/informix and INFORMIXDIR on your target computer is /usr/local/informix, create the /usr2 directory on the target computer and symbolic link as follows:

UNIX Only
On UNIX:
```
mkdir /usr2
ln -s /usr/local/informix /usr2/informix
```
End of UNIX Only

Windows Only

On Windows:

Create a shortcut from your source INFORMIXDIR to your target INFORMIXDIR. For information on how to create a shortcut, see your operating-system documentation.

End of Windows Only
Add the device that contains the volume pool that contains the bootstrap file:
```
ism_add -device device_name -type device_type
```
Add the remaining devices for the other volume pools.
Mount the storage volume that contains the most recent backup from the ISMData volume pool.
Mount the remaining storage volumes.
Scan the volume for the most recent bootstrap save set:
```
ism_catalog -find_bootstrap device_name
```
ISM displays the ssid numbers for all bootstrap save sets on the volume. Record the most recent ssid number because you will need to use this number again in step 8.
Recover the most recent bootstrap save set:
```
ism_catalog -recover
```
Enter the most recent bootstrap save set number you recorded earlier in step 6.
Wait until the following message appears. Ignore the warning and proceed to the next step:
```
nsrindexasm: Didn't find earlier versions to recover!
WARNING: The online index for hostname was NOT fully
recovered...
```
Shut down ISM:
```
ism_shutdown
```
Recover the res.R file from the source database server.
The res.R file contains the resource configuration information for the source database server.

UNIX Only
On UNIX:
```
cd $INFORMIXDIR/ism
rm -rf res
mv res.R res
```
End of UNIX Only

Windows Only
On Windows:
```
cd %ISMDIR%
del res
rmdir res
move res.R res
```
End of Windows Only

Important:

Perform step 11 for disaster recovery only if you did not issue the ism_add -admin command on the source computer because it was unavailable.

Create the following temporary file and then run the nsradmin command against that file.
