SAP Note 15626 - SAPDBA: Invisible password for SAPDBA

Symptom:

Password input for SAPDBA

Other terms

ops$, OS_AUTHENT_PREFIX

Solution
The ORACLE username and password can be transferred to sapdba with the flag "-u username[/password]".
The default is "-u system/manager", that is, in this case the flag can be omitted in the call up.

From Version 3.0C onwards, the entry is invisible. In any case, there are limits to the length of the password (BS-dep. > 8 characters). If a longer password must be used, it can be entered with "-l " but once again transparently. This option is also needed to store a password in a file and have the password transferred via diversion
" -u system < ".

As a thrid solution, the OPS$-User-Mechanism can be used: (see ORACLE Documentation under "OPS$" or SAP Problem Note 8523).
The call would then be:
"sapdba -u / ..." (... for possible additional flags depending
on the purpose)
