Server Administration :: Oracle 10g - First Put Server Into Actual Use - Not Working?
Aug 12, 2010
We are using oracle 10g in linux machine which runs as server. And there are around 25 clients which run at the same time parallel to each other. I am new to oracle 10g and also for client-server version of database. I faced some problems when i first put the server into actual use.
-> Users have been created and tablespace is USERS and temporary space is TEMP. RESOURCE privilege is given.
-> Some times login fails for some clients.
-> Some times all the client login will be successful.
-> Query execution will be sometimes fast, but some times it takes too much time.
-> Some times the connection will be lost and again I have bring UP the server.
to maintain the oracle server.
-> Should I have to make any configuration settings in the server.
-> Should I change any values in the server.
-> Is there any way to properly maintain the server.
essentially create data fragmentation within the datafile resulting in the db having lots more space to write into but not actually freeing space, even if you shrink the file it doesnt free space or do a reorg?
We have as an example a DB with 2 billion rows of data in 1 table, no partioning just one large table.
We have worked out that we can probably delete 1 billion rows or even better only keep a rolling 3 month window of data.
What would be the suggestion on deleting this data and reclaiming the disk space to actually see additional disk space made available at the os level.
deleting the data and reclaiming the space.
Through reading it looks like it might be something like, delete, creating new table space partitions from this data. This in theory would create new a tablespace in newly created data files which would result in the data being reorganised and taking up less physical space and when completed you point to the newly created partitions and drop the old tables.
We are using Oracle 10g and have 10 tablespaces defined for our Database which have 108 tables. Size of 108 tables is around 251 MB as seen during importing the dump. While creating these 10 tablespaces I used below parameters for allocation of space
SIZE 1M REUSE AUTOEXTEND ON NEXT 1M MAXSIZE 1M;
which set the initial space for 10 tablespaces to around 1032Kb each. Now my Question is after importing the dump , how the disk space for 10 tablespaces increases to 398 MB in total ?
Is there any relation of Tablespace disk space and Actual Data present in the tables ?

if there are any problems with updating statistics? My manager told me that they had big performance issue when they updated the statistics of whole database. Is this a rare case?
I know the advantages of updating statistics,but are there any dis-advantages?
It seems that dml trigger doesn't fire when lob field is being updated using dbms_lob package. As it stated in Oracle documentation:
Quote:Using OCI functions or the DBMS_LOB package to update LOB values or LOB attributes of object columns does not cause Oracle to fire triggers defined on the table containing the columns or the attributes.
I need to know that table was updated (or is about to be updated), how can I do that in case it is lob field that is being updated?
i am trying to install Oracle 10.10.2.0 on Windows Server 2003 standard x64 Edition Service Pack, but when i try to run the installer or open DVD it gives me below error.
"The image file D: is Valid, but is for a machine type other than the current machine."
I was trying to delete the database in the test server. When i was deleting listener was already stopped, i continued deleting using dbca, it shown me some alert that datafiles cant be deleted because system could't find database, since listner was stopped so only service was deleted(the one showing in the windows administrator toolsservicesOracleServiceTEST).
All the datafile parameter files are still there. How can i delete the datafiles and parameter files belongs to that database or how to create the deleted service, so that i will start the listener and do the complete deleting of the database.
I am trying to find the unix process for one of my application in the database but I am unable to view the same. To simulate, I did the following.
1. My database runs on different server. 2. I invoked "sqlplus" from another unix box to login to the database. 3. I found that the process id (ps -ef |grep sqlplus). 4. When I execute the below mentioned query it does not display the process id that I am looking for. But the osuser, username, program and machine details are correct. How can I know the process details from the database?
SELECT SYS.GV_$SESSION.OSUSER, SYS.GV_$SESSION.USERNAME, SYS.GV_$PROCESS.SPID, SYS.GV_$SESSION.MACHINE, SYS.GV_$SESSION.PROGRAM, SYS.GV_$PROCESS.PROGRAM ,SYS.GV_$SESSION.SQL_ID FROM SYS.GV_$PROCESS, SYS.GV_$SESSION WHERE SYS.GV_$PROCESS.ADDR=SYS.GV_$SESSION.PADDR and SYS.GV_$SESSION.USERNAME='TEST' and SYS.GV_$SESSION.MACHINE like '%hostname%'
I want to install Oracle 11g R2 in windows 2008 64 bit server. How can I know whether my server is ready to install Oracle ie is all components are available in server or any patch is to be applied etc.
I'm trying to connect a oracle client application on the client machine to a remote oracle server on the server machine but i get a connection fail.
On the server machine I configured oracle server in the following way:
Installed oracle server. Created a database "DB_Test" with the database configuration assistant Created a LISTNER with the Oracle NET Manager with the following parameter:
Protocol: TCP/IP HOST: server pc hostname (ENZOVAIO) or server machine address ip (192.168.0.71) in the network lan Port Number: 1521 Created "dbtest" service with the Oracle NET Manager with with the following parameter: Service Name: "dbtest" Protocol: TCP/IP HOST: server pc hostname (ENZOVAIO) or server machine address ip (192.168.0.71) in the network lan Port Number: 1521
All services on the server machine are running and I opened port number (1521) in the router. On the client machine I installed SQL PLUS and SQL Developer.
With SQL Plus as by the official documentation I have entered the following command:
CONNECT username/password@[//]host[:port][/service_name]. In my case is: CONNECT SYSTEM/oracledb@//ENZOVAIO:1521/testdb.
With SQL Developer I have entered the same parameter.
But with both SQLPlus and SQL Developer the connection fails.
We performed image copy of production Oracle server (OS and instances) to a backup server. After a few weeks, we try to restore a latest Oracle database backup from production server to backup server. As we know, Oracle instance must be unique on the network.
Even we log on to backup server and bring up the instance, I think that still point to production instance since all init file, TNSNAMES.ora and listener file are still same. If we restore the database, we will end up bring down the production instance and restore on top of productions. How to change instance name on backup server including TNSNAMES, sqlnet, listener files in order for us to restore Oracle database from production to backup server?
I recently installed Oracle 10g on my windows Xp laptop. It has become considerably slow since then. I want to start the database server only when I need it, and not every time I start my laptop. I looked around in OEM and did found a way.
I am connected as System. It was the only user I set-up a password when installed the database on personal computer.
SQL> alter user sys identified by mypass007 2 / User altered. SQL> connect sys/mypass007 ERROR: ORA-28009: connection as SYS should be as SYSDBA or SYSOPER
We will be having a meeting with our client regarding their Database Server Migration (They are planning to buy a new server). Their current database is Oracle 10gR2, they will not upgrade to 11g, they just plan to migrate to a new more powerful machine.
I was planning to ask the following questions.
1. Specifications of the current server and the new one. 2. Operation system (I think they will use same OS, just an updated one) 3. Can the business afford full downtime on current servers? 4. Size of the DB, because it can take hours to move large files.
And is there documentation regarding Server Migration (Change of machine only, not database upgrade or anything,
Sometimes our db server goes in hanging condition. It does not save any transaction & user waits for long. When I restart, it starts working fine.What should I do, I mean regarding diagnosis & performance tuning.
In Process of upgrading Oracle EBS 12.0.4 to 12.1.1 I updated the $IAS_ORACLE_HOME/appsutil/jdk to jdk 6u24. After replacing the original jdk with jdk 6u24 when I attempted to start the apps adoacorectl.sh failed with below error.
Quote:ld.so.1: /d4/app/oracle/apps/12.0.0/vdd700/web/10.1.3/appsutil/jdk/bin/java: fatal: libjli.so: open failed: No such file or d irectory
I followed below steps to update the jdk 1. extracted the jdk-6u24-solaris-sparcv9.tar.Z to $IAS_ORACLE_HOME/appsutil/jdk 2. Copied lib from old jdk to $IAS_ORACLE_HOME/appsutil/jdk 3. Copied lib from oldjdk/jre to $IAS_ORACLE_HOME/appsutil/jdk/jre 4. The java was not infact in jdk/bin rather it was /bin/sparcv9 so I copied them to /jdk/bin. The same way copied the executables from /jdk/jre/bin/sparcv9 to /jdk/jre/bin .
I have some requirement wherein I need to install Oracle 9i database server (9.2.0.7). I am not getting it on Oracle website. where can I get the download.
i am installing oracle database 8.1.7 on dell server power edge 2650 first time database successfully installed but when i want to crate new database by Database Configuration Assistant it is not working for new database creation.
We have changed the SYSDATE to 03-FEB-1994 in our AIX machine where oracle11g database is running. Once the sysdate is changed db and listner are getting down immediately and its generating the core in $ORACLE_HOME/dbs
This AIX machine is for PT test and as per one requirement we are changing the sysdate. Moreover, we found that database is getting down if we change the sysdate till 1999. If we change the sysdate to 2000, then we are not seeing any issue.
Below point is for additional info. After changing the sysdate and trying to connect to the db user, we are getting the below issue.
