Server Administration :: User See Only Synonyms And Avoid Looking At Definitions
May 26, 2010
I have granted connect,resource privilege to a user 'TestU' and have create several synonyms in the schema using the public database link. What worries me is that the user 'TestU' can view the all_ and users_ dictionary views, which makes him accessible to all public database links and all user specific objects definition.
Is there a way to restrict the user to see only the synonyms and avoid looking at their definitions
Suppose two users (CONNECT and RESOURCE roles) A and B who work on the same project. How can B create synonyms of all tables of A without asking admin to do that? Of course, we assume that these users have the CREATE SYNONYM privilege. My problem is that B does not have access to user_tables of A, so he cannot obtain the list of A's tables to create synonyms.
Sunddenly my exports hangs at 'exporting cluster definitions'. I had been using this database since last 4 years and it never cause a problem or hangs at this level. here i'm pasting my screen details. it is my production db.

I found there is clear password in the xml file in the process of Oracle instance creating. The process like below
1, when using the following process to create the instance
Login as user Oracle /home/Oracle11home/bin/dbca -createDatabase -silent -templateName /home/Oracle11home/assistants/dbca/templates/Small.dbt -gdbName testDB -sid testSID -sysPassword [b]testpwd[/b] -systemPassword [b]testpwd[/b]
2. Found the file in $ORACLE_HOME/checkpoints/dbca/OraDb11g_home2_oracle_creation_checkpoint.xml , it listed the sys and system passwd (like testpwd for sys and system password) directly.
I have a strange problem when creating a view in user from another user
I have a user called "Cash_tst"
its syntax creation is
-- Create the user create user CASH_TST identified by "" default tablespace CASH temporary tablespace TEMP profile DEFAULT quota unlimited on cash; -- Grant/Revoke object privileges grant connect to CASH_TST; grant dba to CASH_TST; grant resource to CASH_TST;
-- Grant/Revoke system privileges grant create any view to CASH_TST; grant unlimited tablespace to CASH_TST;
I want to create a view
CREATE VIEW TAMER AS SELECT * FROM [b]AROFL[/b].RA_CUSTOMER_TRX_LINES_ALL_BEFO
"AROFL" is another user on the same database when try to create the view "tamer" i got message of "insufficent privilege" although i granted "create any view" to the user "cash_tst"
i have created form. one field is there "Payment_terms" at line level. for that i created LOV containing 3 fixed Payment terms. my requirement is that Avoid the user to select twice the same value from LOV.
I did an export from 8.1.7 and imported in 10g. All the tables were imported. I created all the users and gave them necessary grants. when i try to compile synonyms for this schema i imported,I get the following error in enterprise manager:
Failed to compile: ORA-00980: synonym translation is no longer valid
I cannot login to my application with these users even though they have all grants. I receive the following error:
i want to do a schema export from Database A. There are hundreds of users under this schema.I have to import this schema into other database say B. My question's are:
1) Do i need to pre-create only schema user or all the users under it.
2) Will the schema export all the roles,procedures,packages,synonyms,funsctions and triggers?
We have installed Oracle RAC 11gR2, installation was all successful.But i cannot see ASMSNMP user to login as ASM enterprise manager .If i tries to login as sys (even after assigning SYSASM role) he cannot login.

Whenever I create a table using login A, the table gets created successfully. But when I query the dba_objects, the object owner is different, login B. What might be the reason behind this?

I am using TOAD to monitor user sessions. I have a user who uses nearly 80% of Overall resources in the mornings. He calls me daily and say that his work is done. But even then the TOAD shows that he is using same resources for some time.
My question is can i kill the session once he confirms his work is done OR do i need to wait till the redologs are cleared.
