Server Administration :: Check Status Of Listener And Read Only From DB Query?
Jun 13, 2010
I need to display the parameter and status of DB for listener and Read Only.
I know those value could be get from command line , but could we get the values of Listener and Read only by SQL/PlSQL? So I can get it through the query of DB.
My application is opening a lot of sessions in my DB server. I applied resource_limit=true and idle_time=15 min. ans assign this profile to all application user.
Now I am seeing a lot of sessions having status sniped in v$session.
I want to clean up these sniped sessions and what they mean.
We are upgrading 10.2.0.4 enterprise edition single instance to 11.2.0.3 enterprise edition single edition manually. What should the listener status while doing upgradation. This is my first upgradation project.
One of our developers team member had created a Anonymous block program to do something in the Database, and he forgotten and terminated the session without confirming the program's status, whether it was fully ran or not.
Is there any way to check out the status of this, which happened yesterday?
How to find out the status of the import job(how much work is done, ETA), i have started the job few days back it still running on the server. i am using import not datapump, because i got the dump which took with export. DB version is 11.2.0.2.0
for datapump i know i can use the following queries, but these are not giving any output l think these are only for datapump
select sid, serial#, sofar, totalwork from v$session_longops; select sid, serial# from v$session s, dba_datapump_sessions d where s.saddr = d.saddr;
I am manually committing the form by writing commit statement in key - commit trigger for some reason.
Everything is working fine. I want to display a message if some necessary fields are not filled properly, like if a user filled half table and mistakenly he press the commit button. Here I want to show him a message that you can't saved the data because the table is not completely filled.
I was working with forms and found a problem related to accessing of status of checkbox. In a block with multi record to be checked, if we want to check all the checkbox status which is already clicked, Then what should i do.
Now i am using the function Checkbox_check as:
if Checkbox_Checked('FVA.STATUS')
But the problem with this function, it is giving status of last clicked checkbox only.

We are in 11gR2 in windows 2008. Our database is 2 nodes rac. I got alert message below.

I did check the cluster resources by srvctl status resource -t and all of resources are in online and none of them i saw in intermediate state. Is there any other command and option to investigate this error?
I am in charge of several instances located on a Linux server CentOS, virtualized on a ESX 3.5 environment.
From time to time (every 4 to 5 days), I have some errors in the alert.log. Last occurence was last night :
Corrupt block relative dba: 0x01004e12 (file 4, block 19986) Fractured block found during buffer read Data in bad block: type: 6 format: 2 rdba: 0x01004e12 last change scn: 0x0000.131aaa5b seq: 0x2 flg: 0x04 [Code] ........
We are doing user manual backup (with BEGIN/END BACKUP) every night at 8PM, ending at 9PM approx. Then, fractured blocks never occur during backups. At 1AM, the maintenance window is opening, thus explaining the GATHER_STATS_JOB job.
When I check corruption on early morning, I am always unable to reproduce the problem. DBV is OK without issues. We never had a problem with the data itself, whatever it is a table or an index in the reported failed block.
I would like to know what could cause these logical corruption, and how to stop them ?
I am facing a strange issue on 11gR2 (OEL 5.4) standby readonly with apply database.It's throwing 16000: database open for read-only access during SELECT's .
Here is snapshot of errors.
ORA-00604: error occurred at recursive SQL level 1 ORA-16000: database open for read-only access
I have created an user named "Raja" with a default tablespace as "Raja_TBS" along with a datafile "rajadata.dbf". I have taken the tablespace offline
SQL> alter tablespace raja_tbs offline;
Tablespace Altered. when I take a tablespace offline, which means I cannot read or write and the tablespace is currently unavailable for users. I am still able to create a table on the "Raja_TBS" while it is offline.
How can i check a partition whether it has been compressed? just as flowing test,i can not get the information about partition P_L1 whether been compressed.
SQL> Select 2 aa.compression, 3 aa.partition_name 4 From dba_tab_partitions aa 5 Where aa.table_name = 'TB_HXL_LIST';
1. Install patch 6613550 (./rootpre.sh) 2. Install 10.2.0.1 for AIX 64-bit 3. Install 10.2.0.5 Patch Set 4. Create Database 5. Created/Setup LISTENER and TNSNAMES (test connection successful)
After installation of database, everything went well until we tried to restart the server, what happened is that we cannot start the listener, the error was:
TNS-12555: TNS:permission denied TNS-12560: TNS:protocol adapter error TNS-00525: Insufficient privilege for operation IBM/AIX RISC System/6000 Error: 1: Not owner
What i did to resolve this problem is to change the owner of /tmp to oracle, after that i was able to start the listener. ($lsnrctl start) The problem is that our sys admin said that the /tmp directory is being used by the OS and it's owner must be root. But if i return it to root, the listener will not start again. (After server restart)
BTW, our /tmp has enough space so we did not perform the following steps from the installation guidelines:
quick check on a hidden parameter? I need to know the default value and possible values for _serial_direct_read on various releases, I have only 11.2.0.3 available right now and I'ld like to know this for 11.2.x.x 11.1.x.x, and 10.2.x.x.
Below is the query that will show what it is currently which (unless you've changed it) will be the default: auto for my 11.2.0.3. Then to see the options, try to set it to something wrong, my options are false/true/never/auto/always. I think false/true were the only choices for 10.2 and are maintained only for compatibility. But I can't rememebnr 11.1.
