Server Administration :: Default Count Of Oracle 11g Database
Mar 6, 2011I installed Oracle 11g and created a test database in that the default count should be 4196... but it is 4143.. some packages are missing.. even when i'm creating materialized view it is showing some error that packages are missing. what can i do for that? Is my oracle s/w corrupted ? even when i downloaded from oracle site it also shows the same count.

PL/SQL :: Single Long Connection Vs Multiple Short Connections To Oracle Server
Oct 8, 2012A DB server (Oracle 11g) on Linux will support a Web Application Server (Java based) for hosting a public web site.For sending multiple INSERT statements over from the Java Server to Oracle Server, I have two ways to do it:
1) Wrap those insert statements together and send it over with one connection to Oracle
2) Send each insert statement separately to Oracle. As the result, multiple insert statements are sent and accordingly multiple connections to Oracle are needed.
Advantage of option 1 is just using one Connection. Disadvantages are that Oracle will then need to parse the statement string into multiple separate insert statements, and then loop through them to execute each. This may be costly in CPU sense.
While the option 2 may have quicker execute of each insert statement, but will need to create multiple connections.If the number of users is known and stable (such as intranet), I would prefer option 1; while for the internet there could hundreds concurrent users at the peak, I lean towards the option 2.

Server Utilities :: ORA-01918 / User (SDE) Does Not Exist
May 25, 2010I'm trying to move a complete tablespace with all associated schemas/users and data.
The command that I'm using is as follows:
impdp DP_USER/DP_USER directory=datapumps network_link=backup tablespaces=SDE
DP_USER has the IMP/EXP_FULL_DATABASE, as does the target of the database link.
The error that I get is the following:
Processing object type TABLE_EXPORT/TABLE/TABLE
ORA-39083: Object type TABLE:"SDE"."VERSION" failed to create with error:
ORA-01918: user 'SDE' does not exist
The SDE tablespace has objects from the SDE schema, but the SDE schema does not seem to be created along with the tablespace. How do I cause it to be?

How To Kill Inactive Connections Automatically
Apr 26, 2011i was gone through the below link
[URL]
so when i changed my idle_time value in profile and the when the user exceeds the idle_time value the user still i can see in-active state in v$session.
and when i was tried to execute any query on inactive session that time i got an ORA- error and then session was not visible from v$session.
in my environment inactive session was not getting used afterwards so is there any way to kill that sessions automatically once reached idle_timeout value.
lets say i have 50 max sessions, out of which 10 are inactive state and 40 in active state .what if i created one more sessions will that give me ORA- error stating max sessions reached or it will kill the one session which are in-active state.
Performance Tuning :: SSL On Database Connections?
Oct 10, 2012insight into the overheads for mutally authenticated SSL for database connections? This is over a fast local network, to a RAC cluster, with DB firewall in front. There's always a large element of "it depends"
Information I'm interested in are things like latency for initial session setup and subsequent data transfer. Also the increase in network packet size, and the increase in CPU cost for the database server. I guess there is some implications for session memory usage as well.
PCI - Auditing Connect / As Sysdba - Connections?
Feb 15, 2012I have a problem with a PCI DSS - requirement in Oracle 11.2. (PCI DSS = Payment Card Industry Data Security Standard)
Problem:
we connect via ' ssh -2 -X -l oracle hostname ' to the databaseserver and become os-user 'oracle'. we have also two offshore locations with dba's and each dba comes with his personalized user to the jumphost and then with the above ssh command to the database server.
the problem is that each dba becomes the oracle-os-account and can now connect with '/ as sysdba' to the database.in pci-dss this is not allowed !
now my question:how can I audit these '/ as sysdba'-connections and prove which user connected at which time with the '/ as sysdba' command ?
database is in audit mode. we log to syslog on linus redhat 5. I know one solution could be setting "SQLNET.AUTHENTICATION_SERVICES" parameter to "NONE" in sqlnet.ora file will make it not possible to connect to the database without a password as sysdba. (sqlplus / as sysdba). but we have to many applications and jobs and this is not really the solution in this case.
I think I can only solve this problem with personalized OS-user DBA-accounts in the dba-goup on os-site and os-user oracle should not be used for the future ?? I also need personalized dba-user-accounts in the database. using sys and system is not allowed. this users has to be locked and only for special administration work could it be unlocked.

My idea: using fork to create multi sqlplus to connect but it cant o_0
If all users can connect to Orcl db, I can count real user connections.

Restrict Client Connections To Just Two Specific IPs Over Oracle Listening Port?
Jan 18, 2013I was asked if it was possible to restrict which users / or client IP's connect to my Oracle 11.2 database. I guess I could just shutdown the listener and have me and one other DBA connect to it via SSH / LOCALHOST but I was wondering if there was a more DBA specific way to restrict client connections to just two specific IP's over the Oracle listening port?
View 5 Replies View RelatedOracle Listener Log Entries Missing And Database Not Allowing Connections
Mar 20, 2013We have a custom portal application that uses a bunch of application servers. Our connection pool max size is 1100. For the past two days, we had two incidents when the cpus reached the max limit and the db was not allowing connections to come thro' for 10 minute periods. The alert log does not have any entry and the listener log does not have any entry for that 10 minute period.
View 5 Replies View RelatedClient Tools :: Alter Session Of Connections In JBoss Connection Pool
Aug 23, 2012We have a Data Source with min_pool_size (10) and max_pool_size (20). A Data Source is by default a connection pool. By starting a transaction we are retrieving a connection from the pool (i.e., opening it to retrieve data, perform queries, inserts and updates). Our application server is JBoss. An application workflow uses many transactions to build a product. The same connection is not used by the application for the entire workflow; but, it uses and returns them to the connection pool. We do not use Java syntax like "rs.close():"... this is performed by iBATIS.
On the Linux side when we execute a "ps" command (ps -elf|grep -i ora) we see all the Oracle processes. A further refinement of that command (ps -elf|grep -i local=no)shows a list of the "waiting" connections in the connection pool. The DB may be queried with the following syntax:
SELECT schemaname, sid, serial# FROM gv$session where schemaname = 'APP_USER' order by SID;
A list of connected sid and serial numbers is returned, identifying which connections are in use. From here we are able to force the connection to trace by executing the following:
exec dbms_monitor.session_trace_enable(249, 6595, TRUE, FALSE); ! 249 and 6595 being SID and Serial# from query above
There should be no need to execute the inverse, since the connection is returned to the pool when the transaction is committed or rolled back.
exec dbms_monitor.session_trace_disable(249, 6595);
We are trying to trace in order to use the Quest Benchmark Factory. Their instructions request the following syntax be applied to each session:
alter session set events '10046 trace name context forever, level 4';
and again, the inverse should not be necessary.
alter session set events '10046 trace name context off'
When it became too cumbersome to alter each session as it appeared, we issued an "alter system" to monitor (trace) everything. The trace files filled the disk, and four hours of testing was stopped two hours in. Doing a system level trace is probably not a good idea.
My first inclination was to create a post-logon trigger to set trace in the session; however, these connections, coming from an JBoss connection pool, do not logon each time, and I presume that they are not all the "same session".
We opened a support ticket with Quest last Friday and do not have an answer yet. This was the third ticket with them, the first to get Benchmark Factory installed (the original installer did not work). The second ticket was to setting up a shared directory on Linux with a folder on Windows, a setup configuration required by their tool. The third ticket to address this issue.
They needed to contact "the developers" to answer the last two questions. Their latest suggestion is to fix ticket two so we "won't need to trace" anything. How do I set trace in these connections?
