Hi Samid,
Two things you need to work on
SQLERRTEXT : invalid username or password:
***LOG BY2=> sql error 10 performing CON [dblink 550]
***LOG BY0=> invalid username or password: [dblink 550]
*** ERROR => saplikey: failed to connect to the database. [saplikey.c 830
1. Connect user name and passowrd
2. You kernel level, if possible use 740 and try again.
Regards.
