Increasing tablespace quota

Question

Hi
i have a requirement in which i need to increase tablespace size for my schema. actually the tablespace that is given to me is shared by many other 'owners' too but i want the datasize just for me to be increased.
SELECT OWNER,TABLESPACE_NAME,SUM(BYTES/1024/1024) "Allocated Size in MB"
FROM DBA_SEGMENTS WHERE TABLESPACE_NAME = 'DATA_TS1'
GROUP BY OWNER,TABLESPACE_NAME ORDER BY OWNER;
will give this result
OWNER | TABLESPACE_NAME| Allocated Size in MB
30026882 | DATA_TS1 | 170.9375
30042534 | DATA_TS1 | 0.1875
myself | DATA_TS1 | 106951.875
now how can i just increase quota for 'myself'?
Can this be done? and if so can you plz provide me with syntax?

ALTER USER myself    QUOTA x M    ON data_ts1;where x is the new number of megabytes.
There is no way to guarantee that other users won't use the newly created space if they have sufficiently large quotas. If you want to make some space available only to a given user, then you need a tablespace where nobody except that user has a quota.
