I make a pardon the binary which I chatr'ed was sqlplus
rgds
Hi all
I have more information, I did a chatr to check differences between working server oracle binary and the non working.
I see two differences, in the server which LD_PRELOAD doesnt cause problem oracle binary has these two attributes:
explicit unloading disabled linkage table protection disabled
Does anyone know how can I change these attributes with chatr?
Cheers
