Server Administration :: Oracle Shutdowns While Setting The RESOURCE_MANAGER_PLAN
Jun 10, 2010
The Oracle Instance gets down while setting the Resource_manager_plan with internal error in trace file:
SQL> ALTER SYSTEM SET RESOURCE_MANAGER_PLAN='EST_EXEC_TM';
ALTER SYSTEM SET RESOURCE_MANAGER_PLAN='EST_EXEC_TM'
*
ERROR at line 1:
ORA-03113: end-of-file on communication channel
I can not change the parameters RESOURCE_MANAGER_PLAN, at first, I set the parameters to DAYTIME,but when I restart my db,the parameters hold old values named MAXCAP_PLAN. Why?
SQL> select * from v$version; BANNER -------------------------------------------------------------------------------- Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - Production PL/SQL Release 11.2.0.1.0 - Production CORE 11.2.0.1.0 Production TNS for 32-bit Windows: Version 11.2.0.1.0 - Production NLSRTL Version 11.2.0.1.0 - Production
My server version is:- 10.2.0.3.0 Here is the INIT Parameter file.
My question is, how it will affect if I configure the UTL_MAIL package by executing the Scripts ("utlmail.sql" and "prvtmail.plb")? And setting the Parameter SMTP_OUT_SERVER=''?
I have a simple question about database sessions. The value of parameter "sessions" is set to 500 and the users connect to database through an application server(Jboss). There are more than 500 users connect to the database through application.
My question is, how more than 500 users can connect to the database without any issue, if we set the value of "sessions" parameter to 500?
Users are reporting that are unable to use the NVARCHAR(4000) due to the character set which is set in the database.
Currently NLS_CHARACTERSET is set to AL32UTF8 and NLS_NCHAR_CHARACTERSET from AL16UTF16
They want me to change both the character set to UTF8, so that they can use the NVARCHAR2(4000) datatype in their tables.
As UTF8 is the subset characterset and I did the cs scan and this found characterset can't be modified to UTF8 and there may be the data dictionary corruption.
Is there any other way so that users can use the NVARCHAR(4000) as datatype. And the reason why NVARCHAR2 is required is, users are trying to import the data from other database which is using NVARCHAR(4000) as one of the field.
I've been following Metalink note 602952.1, 309815.1 and 605828.1
metalink note 602952.1 states Quote:Note: Keep in mind for ASMLIB disks you will need to use the /dev/dm-* disks instead of the /dev/mapper/mpath* devices since they are present in the partition table ==)> /proc/partitions and ASMLIB will look at that file during the disk discovering phase. If you do not use the disks located at /dev/dm-* then ASM will not be able to discover them. and to create ASM disks with Quote:/etc/init.d/oracleasm createdisk DISK1 /dev/dm-<disk><partition> Also further stating Quote:NOTE: When scanning, only the device names known by the kernel are scanned. With device-mapper, the kernel sees the devices as /dev/dm-XX. The /dev/mapper/XXX names are created by udev for human readability. Any configuration of ORACLEASM_SCANORDER or ORACLEASM_SCANEXCLUDE must use the dm prefix.My environment is RHEL5 and towards the end of the note it says Quote:Note: On release RH 5 the /dev/dm-N devices are not persistent, starting, these devices are no longer created by udev. So release RedHat 5 you can create the ASMLIB disks on the /dev/mpath/<partition> or /dev/mapper/<partition>
Therefore I created a ASM disk using /dev/mapper path and it is only visible on the node it was created. Even after scandisks on other node it is still not visible when listdisks/oracleasm-discover
I've also tried creating the asm disks with dm-12 option and the same, disk get created but not visible on the other node.
Moreover if I restart the oracleasm restart the disk disappears from the node that it was visible Quote:
[root@db2 ~]# /etc/init.d/oracleasm createdisk vol1 /dev/mapper/mpath6p1 Marking disk "vol1" as an ASM disk: [ OK ] [root@db2 ~]# ls -l /dev/oracleasm/disks/* brw-rw---- 1 oracle dba 253, 12 Nov 8 10:22 /dev/oracleasm/disks/VOL1 [root@db2 ~]# /etc/init.d/oracleasm scandisks Scanning the system for Oracle ASMLib disks: [ OK ]
[code]....
But disk lable is there and could be seen from both nodes on the same partition Quote:
head /dev/mapper/mpath6p1 VOL1ORCLDISKVOL1
My suspicion is on multipath configuration. I've tried both (not at the same time) combinations given below.
regarding sizing undo tablespace and undo_retention parameter.we have to implement the database in production system with 40 users but how much space should be allocated to undo tablespace is there any propotions related to virtual memory and the parameter.i have gone thru oracle doc's and some related sites.its an ERP aplications that contains 20 modules .I am an new one to this dba level
We are running a brower based client application in a J2EE container on weblogic, connecting to the database using proxy authentication from a connection pool.
We want to set the logging level in the front end, which should set a PL/SQL package/session variable to the respective value.
Any subsequent calls to the DB layer (stored procs) would then log appropriate messages depending on what the logging level has been set to.
The trouble is that the calls to be database are not persistent and in different sessions, and therefore the second call (i.e. the call to the stored proc) would not 'know' what the first call (to set the package variable) has done.
Alternatively we can change all the stored procedures to accept an input parameter denoting the logging level, but I am sure there are other better options.

SQL> ALTER SYSTEM SET ENCRYPTION KEY AUTHENTICATED BY "XXX"; ALTER SYSTEM SET ENCRYPTION KEY AUTHENTICATED BY "XXX" * ERROR at line 1: ORA-28368: cannot auto-create wallet
As you can see the directory is not created.
ls -ld /oracle/10.2.0.1.0/network/admin/encryption_wallet ls: 0653-341 The file /oracle/10.2.0.1.0/network/admin/encryption_wallet does not exist.
The directory above where I want to create my wallet is owned by oracle, which is the user I am running sqlplus as (see below)
I am having a few issues trying to set up a physical standby database.
The primary database has a different naming structure than the standby and they are at different sites.
Physical is /var/hpsrp/ctrorp03/oradata/u0x/<DB_NAME>/<DB_UNIQUE_NAME> and standby is /var/hpsrp/drforp03/oradata/u0x/<DB_NAME>/<DB_UNIQUE_NAME>.
I have set db_file_name_convert to '<PRIMARY PATH>', '<STANDBY PATH>' times the number of paths as pairs. I have created a blank database for standby and having taken a full backup of primary with control file and standby control file.
Now I hit the issues:
The DB incarnation numbers are different. When I try and do a normal restore e.g. set dbid, restore controlfile; mount; it fails as it is trying to find files in the primary structure and not standby structure. When I try renaming via set newname or auxname it can't find files to restore I guess due to the incarnation id's. If I set the incarnation id and try to restore backup it fails as the incarnation id's don't match.
I have tried looking through various forums and the documentation but can't find a solution, probably can't see the wood for the trees though as there is so much.
i need to retrieve html using oracle and setting the correct user agent.I used the ut_http package and his fuction utl_http.request_pages.
I worked perfectly for me, execpt that i could be able to setup the correct user-agent.I read the documentation and i found that this instruction utl_http.set_header(req, 'User-Agent', 'Mozilla/4.0'); should fix my problem, but when i used it, nothing changed and the webserver didn't recognize the correct user agent.
I post downhere a piece of the pl-sql procedure i made (it seems that i could find the correct "link" between utl_http.set_header instruction and utl_http.request_pieces instruction)
We are in the process of setting up a DR environment for our SAP and Oracle databases . The netapp and our architects came up with solution as follows .
1.Standby databases are built for all production databases. 2.The SAP file systems are replicated to the secondary site 3.The Oracle logfiles and controlfiles are replicated by netapp snap mirror every 10 mins interval 4.The database is recovered through recover standby database every 15 mins at standby site 5.Please note there is no data guard involved . 6.To test the failover , the mirror is broken .The standby controlfile is replaced with Production controlfile and Redo logs files. 7.The standby database issued a startup comnmand and it worked .
Would like to know whether the step 6 is a correct approach ? I tried to convince the architects that this will result in a very disastrous situation for us but none is listened to .
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.
