hi,

balavignesh .. mahesh had given u link of document so that you can study and clear your concept related to RBS & u can understand why this 0ra-01555 occurs...

but if you want to increase the size of your rollback segment .. then first of all you have to find rollback segment whose size you have to increase ....

The following statement alters the maximum number of extents that the RBS_01 rollback segment can allocate.

SQL>ALTER ROLLBACK SEGMENT rbs_01 STORAGE (MAXEXTENTS 120);

note :- rbs_01 is rollback segment name.

You can also create a rollback segment with a bigger size may be as RBS_LG and assign that trasaction to that rollback segment ..
