When I try to start the database service or connect to the write file (using dbeng9) I get the following error:

Error Connection Failed:database error ERROR Assertion failed: 201818 (9.0.2.2451) Checkpoint Log: invalid bitmap page -- transacction rolled back

No log file exists. I had tried to valid or rebuild the database file but the error stops that.

Some tools or procedures for recovering data ?

Thanks for your help

Assertion 201818 indicates a corruption problem with the checkpoint log, which is why you cannot start the database - the checkpoint log bitmap is found to be corrupt before the forward transaction log can be processed.

If you don't have a (valid) backup that you can restore, you should contact Sybase technical support for assistance with salvaging the data from the database.
