Unwired Server Upgrade Stalls if Cluster Name is Longer than 16 Characters

Problem: If an existing 2.1.X cluster has a cluster name that is longer than 16 characters, when upgrading to version 2.2, the 2.2 installer throws this error: Upgrade failed. Cannot find the 32 bit ClusterDB DSN registry key.

Workaround:

Make sure all Sybase Unwired Platform services and process are stopped on the server to be upgraded.

On 64-bit systems, create the following key (all on one line):

HKLM\SOFTWARE\Wow6432Node\ODBC\ODBC.INI\
clusterdb_cluster_32bit

Create the following STRING (REG_SZ) values under the above key
- CommLinks
- DatabaseName
- Driver
- ServerName
- UID, if it exists in
```
HKLM\SOFTWARE\ODBC\ODBC.INI\clusterdb_<clustername>
```
- PWD, if it exists in
```
HKLM\SOFTWARE\ODBC\ODBC.INI\clusterdb_<clustername>
```
Values for CommLinks, DatabaseName, UID, PWD and ServerName should come from the corresponding STRING values in HKLM\SOFTWARE\ODBC\ODBC.INI\clusterdb_<cluster-name>.
Value for Driver should come from the corresponding STRING value in HKLM\SOFTWARE\Wow6432Node\ODBC\ODBC.INI\default-cdb_32bit.
Make a copy of HKLM\SOFTWARE\ODBC\ODBC.INI\clusterdb_<clustername> and name it HKLM\SOFTWARE\ODBC\ODBC.INI\clusterdb_cluster.
Make a backup of sup.properties in SUP_HOME\Servers\UnwiredServer\Repository\Instance\com\sybase\sup\server\SUPServer.
Use a text editor to open sup.properties.
Locate the line that begins with cldb.dsnname=.
Replace the string to the right of the equal sign with clusterdb_cluster.
Save the file.
