I wanted to know the checkpoint information and the interval of checkpoint for my instance.I have checked alert.log file for the same.
Is there is any other way or any view exists to get that information?
after i issue the following command,what checkpoint does it trigger?(full checkpoint or incremental checkpoint):
SQL> ALTE SYSTEM SWITCH LOGFILE;
I found there is clear password in the xml file in the process of Oracle instance creating. The process like below
1, when using the following process to create the instance
Login as user Oracle
/home/Oracle11home/bin/dbca -createDatabase -silent -templateName /home/Oracle11home/assistants/dbca/templates/Small.dbt -gdbName testDB -sid testSID -sysPassword [b]testpwd[/b] -systemPassword [b]testpwd[/b]
2. Found the file in $ORACLE_HOME/checkpoints/dbca/OraDb11g_home2_oracle_creation_checkpoint.xml , it listed the sys and system passwd (like testpwd for sys and system password) directly.
<CHECKPOINT LEVEL="MAJOR" NAME="db_oracle" DESC="db creation checkpoint" STATE="FAIL">
<PROPERTY_LIST>
<PROPERTY NAME="command" TYPE="STRING" VAL=" -silent -createDatabase -templateName Small.dbt -gdbName testDB -sid testpwd -sysPassword testpwd -systemPassword testpwd"/>
</PROPERTY_LIST>
</CHECKPOINT>
I hope to confirm :
1. what is the purpose for oracle to genate the checkpoint.
2, can we remove the file safely ?
3, if there is configuration that we can avoid to show clear password in checkpoint file?
I am running Oracle 9.2.0.1 on Solaris 9. On just about a daily basis we perform sqlldr loads that load on the order of 300000 rows. I frequently see in my alert log:
Checkpoint not complete
Current log# 5 seq# 176431
I have 5 redo logs each of 10M in size. If I check what is going on in v$log and correlate to the alert log when it throws the checkpoint error I always notice that I have one current log (which is good) and the rest are in a status of 'ACTIVE'. It seems that when this happens I get the checkpoint error.
What can I do to get rid of this checkpoint error? Should I increase the size of my redo logs? Is there a good way to go about estimating what size redo logs I should have?
My context on our servers is the following one:
- one ASM instance
- X DB instances
- each DB instance uses 2 or more dedicated diskgroups from the ASM instance
- there is one diskgroup named FREEDISK that contains spare disks
On each DB instance you can see:
- the list and global parameters of all diskgroups using v$asm_diskgroup view
- the list and parameters of all disks the instance is using with v$asm_disk view
So my question is: how (if this is possible) to know the list of (spare) disks in FREE DISK disk group?

I know that you can view all constraints in a table using $USER_CONSTRAINTS or $USER_INDEXES view. What i find difficult is that the information in those views is not really well presented.
I find it very hard to follow. For example, just to find out which columns are foreign keys and which tables they refer to is really tedious. Is there a simpler way to view all the constraints especially foreign keys of a table and including which table columns they refer to in the child table.
I like to see a diagramatic representaion of all the tables involved so i like to see both the parent and the child tables, which columns are related and using which FKs etc. is there an easier way to view this information?

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?

We imaged production Oracle Server ( OS and Oracle and everything) to a backup server. I guess my question shall be how do we access the local instance via this backup server. When we log on to this backup server, we ran sqlplus and connected to the instance but it ended up to connect to production instance. Shall we stopped local Oracle services and change init.ora, tnsname, or listener files in order not conflict with production instance?

create an ASM (Automatic Storage Management) instance using dbca. At first try I mistakenly skipped the part where I click on ASM Parameters to add /dev/raw/raw* as my asm_diskstring so it created an ASM instance. When I get to the next page ASM Disk Groups, I selected Create New and I did not have the desired display, because of the step I missed.
I went back to do some cleaning up as follows:
1) Edit the oratab file to remove the ASM entry
2) backed up these files by renaming to old-<filename>
old-ab_+ASM.dat
old-hc_+ASM.dat
old-lk+ASM
old-orapw+ASM
old-spfile2+ASM.ora
3) killed the following processes (kill -9):

oracle 1592 1 0 22:52 ? 00:00:00 asm_psp0_+ASM

4) Run the following as root:
/u01/app/oracle/product/10.2.0/db_1/bin/localconfig delete
5) Restarted the database
Now when I try to go through the steps to create an ASM instance, at the point after I enter my ASM Parameters, I get the following prompt:
"DBCA will now create and start the ASM instance. After the ASM instance is started you can create the diskgroups to be used as storage for your database."
I click OK. Then I get the error message:

I got this error after i patch to 10.2.0.4.0. Before patch, database running smooth.
I shutdown as usual using shutdown only.
Find an appropriate script to automate Oracle DBs in one server? This db server have 6 instances. We always done the starting up and shutting down manually, although we have a reference script that does this but in Oracle v7.3.4. We do want to include the automatic start/stop of dbconsole for accessing it via OEM.
