We 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.

My problem:
+ Oracle 11g
+ Centos 5.5
+ I create many users by shell script (user01, user02, user03 ..... user0n)
+ How can I connect all user to Oracle database in Centos (may be create connect.sh) - command line env ?
......
// user01 , user02 ... ---===> connect Oracles ?
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.
insight 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.

View 1 Replies View RelatedI 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 RelatedA 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.

I performed a switchover test of my Exadata databases last night. Both databases are running 11.2.0.2 (BP7) on top of GI of the same version.I'm using Data Guard Broker to administer the Data Guard configuration.
I have, as you'd expect, the standby_file_management set to AUTO, so any file changes/additions/deletions that are made on Primary should be applied to Standby also.And they have been. Until last night.
When I had switched over to running Primary on the Standby site, I got this error message:

ORA-25153: Temporary Tablespace is Empty
I checked and my two temp tablespaces existed, but had no files in them. These files are 200Gb and 448Gb in size, so you'd think you'd notice them going missing. This wasn't by any means the first time we switched over (and, yes, I did create temp files for Standby when I built it and first switched over)
We've switched over to Standby multiple times and even ran a whole day's processing against it and haven't seen this. Ultimately, it wasn't a big deal, because I just created a tempfile for each of the tablespaces and off we went.Nothing in MOS seems to mention something like this. Basically, it looks like the switchover process decided to eat my tempfiles but keep my temp tablespace defintion. Odd.
OS: Solaris
DB: Oracle 11.2.0.1 EE
Not Using ASM or RAC
I have a Production database that is in archivelog mode and a Standby DR server. Both servers (Prod, Standby) have exact same structure and db name/version.
We manually scp archive logs and recover them to a manual standby database via SQL Scripts "cron". (I.E. set autorecovery on; recover standby database;)
We recently got out of sync with our log files and have not been applying them to the standby. As part of Prod Maintenance, these log files were deleted and are not available anymore.
I've tried several ways to "rebuild" our standby database. I have tried to Shutdown prod, backup all the db files and scp them to standby, re-create standby controlfile and startup mount and recover standby. Every time I try to apply a new archive log via recover standby, these are the errors:

When I check v$log_history, the new logs have not been applied. I've also tried the "Restore from incremental backup via SCN" method with same results. Is there a way to re-create the standby clean and ensure that the log chain that is currently broken gets fixed or reset? I would eventually like to get DataGuard in here, but that's not the case at the moment.

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.
I am abolute new in PL SQL and I am working on following topic:

- if not ...... simply go on
I tried the following:

I fetched the result into a variable entries
if entries > 0 .....
MY problem is the following:
If there are entries (entries>0) --> it works
If there are no entries, entries is not 0 but 'no data found' --> crash
I cannot work with Exceptions because this all happens in a Loop which must go on in both cases!
I 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.
