Hi Praveen,

Welcome to the forum and the dba world.

Have a go thro of Useful Sybase ASE Topics

Will you be a dba on a small environment or will you be working on a large environment. If its the latter, theres nothing like picking their brains and learning from them. It helps a lot. If its in a small env and you are the only dba, its not bad as such, but you need to put in a lot of reading.
