Two-phase commit

To use two-phase commit with ASE servers

Connect to an ASE.
Add an external login entry for the DirectConnect server for the “probe” login which is used to recover two-phase commit transactions. The Oracle login that is used must have the necessary privileges to recover transactions for any user.

For example:
```
sp_addexternlogin dco_server, probe, system, manager
```
Configure the DirectConnect server to use two phase commit.

For example:
```
dco_server...sp_configure dco-server, two_phase_commit, 1
```
Shut down and restart the DirectConnect server.
Shut down and restart the ASE.
