Hi Guru,

I am using oracle 8i, SAP 4.0b, OS sun solairs 7.5.

I want to increase tablespace through sapdba but default path file comes in sapdata3 and i want to in sapdata1. Because i have space in sapdata1. How can change datafile path. Please explain with step by step.

I am given default path show in sapdba

c - New size: 2088960 K

File system: '/dev/dsk/c68t3d0s3'

Select a number or q(uit) ==> 0

Filesystem: '/dev/dsk/c68t3d0s0'

Filesystem block size: 8192

Filesystem fragment size: 1024

ORACLE block size: 8192

SAPDBA: For performance reasons, these three sizes should be equal.

Continue or choose another file system!

Do you want to continue? (y/n) [y] ==>

If i select y then what is the harm and if i slect n then how can increase tablespace in sapdata1.

Please its very urgent.

Thanks in advance.
