Oracle 10g XE startup time

Hello,
Correct me if I'm wrong but I've been looking for this kind of topic on this forum but couldn't find any.
On my Dell Inspiron laptop (Windows XP) with 2Go RAM and dual core Intel Centrino @ 2GHz, it takes about 50 to 60 seconds for the "OracleServiceXE" service to start...
Is it the expected average startup time ? If not, how can I disable a maximum of startup time consuming functionnalities ?
I'd like to be able to use OracleXE as a lightweight database like MySQL or Postgresql.
Thanks for your tips !
Fred

One of the biggest issues with XE startup is XE shutdown.
When XE starts up, it checks whether it crashed the last time it ran. If it crashed, it goes through a very lengthy crash recovery process.
Unfortunately most people do not shut down the database before shutting down their machine. The 'normal' Windows shutdown seems to crash the database to get it stopped quickly.
On my Dell D430 with Vista Business and 2GB RAM, after a crash, my XE starts up in about 55 seconds. After a proper DB shutdown, it seems to come back up in about 17-20 seconds.

Oracle 10g automatic startup in Solaris 10

Good afternoon,
I've installed Oracle 10g Enterprise Edition Server on a server with Solaris 10. I'm trying to configure the automatic startup/shutdown. I've changed dbstart script. I've prepared dbora script and I've created the necessary link to this script in the rc*.d directories.
When I launch dbora start or dbora stop everything is ok, but when I reboot my machine nothing happens.
My dbora script is as follow:
#!/bin/sh
ORA_HOME=/u01/app/oracle/product/10.2.0/Db_1
ORA_OWNER=oracle
if[ ! -f $ORA_HOME/bin/dbstart ]
then
echo "Oracle startup: cannot start"
exit
fi
case "$1" in
'start')
su - $ORA_OWNER -c "ORA_HOME/bin/dbstart"
su - $ORA_OWNER -c "ORA_HOME/bin/emctl start dbconsole"
su - $ORA_OWNER -c "ORA_HOME/bin/isqlplusctl start"
'stop')
su - $ORA_OWNER -c "ORA_HOME/bin/isqlplusctl stop"
su - $ORA_OWNER -c "ORA_HOME/bin/emctl stop dbconsole"
su - $ORA_OWNER -c "ORA_HOME/bin/lsnrctl stop"
su - $ORA_OWNER -c "ORA_HOME/bin/dbshut"

Thanks in advance.

I think that I've found the problem but I need your help. The problem is related to the listener. The file listener.ora doesn't exist!!! In fact the listener starts perfectly when I type the command lsnrctl start, but I don't understand why this file doesn't appear :-O. And of course neither the file sqlnet.ora exists.
I've create these files and I'm going to check. But could you tell how to configure sqlnet.ora to get the file listener.trc?
Thanks in advance.

Hi Linc,
Thank you for yout suggestion.
Export the import makes sense. Do you know of any "How to..." articles for exporting from Tiger?

I want to connect oracle 10g developer run time forms to oractle data base

Hey,
Would any body want to tell me, how come i can connect oracle dev 10g from its forms with oracle 10g data bases

Try asking this on the Oracle Forms forum:

In any case you need to set-up a sqlnet connection from your client to your server. Use the Network Configuration Utility that comes with the Oracle Forms installation.

JDBC connection to Oracle 10g RAC periodically times out

I've been banging my head against the wall for months now and can't figure out why this is and what's causing it.
We have 6x CF8 servers in our environment. 3 of which work perfectly and the other 3 have the following problem. All 6 machines were installed at the same time and followed the exact same installation plan.
When I configure Oracle RAC data source, some of the machines time-out connecting to Oracle from time-to-time.
Config:
Solaris 9 on both CF and Oracle
CF8 Enterprise with the latest updater.
Apache 2 (not that it's relevant)
6 machines, load-balanced (not clustered), identical install and configuration.
data source config:
JDBC URL: jdbc:macromedia:oracle://10.0.0.3:1521;serviceName=dbname.ourdomain.com;AlternateServers= (10.0.0.4:1521);LoadBalancing=true
DRIVER CLASS: macromedia.jdbc.MacromediaDriver
The problem:
Every few minutes, CF starts hanging requests that deal with a specific RAC only data source. After about 30 seconds, all requests bail and generate this error in cfserver.log:
A non-SQL error occurred while requesting a connection from dbsource.
Timed out trying to establish connection
This happens with any RAC data source on the "bad" servers while the "good" servers don't have this problem. The "bad" server doesn't have any problems with direct (non-rac) Oracle data source.
Already tried:
Moving server connections around on a switch (rulling out bad switch port)
Copying driver from the healthy server (but it's the same installer anyway)
Changed from RAC to normal Oracle type data source - works perfectly. So at the moment I have 3 servers connecting to a specific oracle instance and the other 3 connecting to RAC.
Tried googling and searching forums and even Oracle metalink - nothing I could see relevant to this.
It's a shame that after spending a ton of money on CF8 upgrades and Oracle RAC, we can't really utilize fail-over on the database connection.
Any takers?
Thanks,
Henry

DB_RECOVERY_FILE_DEST_SIZE specifies (in bytes) the hard limit on the total space to be used by target database recovery files created in the flash recovery area. You should increase this value.
On the other hand, out from the context I guessed it is a 10gRx database, but you should specify this on your thread, as well as specify os details.

Oracle 10g dataguard Connect-time failover Parameter 15 minutes

Hello,
we running a system with DataGuard in Maximum Availability protection mode and one physical Standby Database. There are two connections between primary and standby. I configured listener and tnsnames to perform a Connect-time failover in case one connection is down. In first place it seemed to work fine but since it has happened that the primary always hangs for exactly 15 minutes until the failover is performed. (ALL redologs need archiving)
I think this must be the default value of a Parameter but reading docs for hours I can't find it.
Can anybody help me?
Best regards
Fritz

It's like this. The connection failover I'm talking about is only between the primary database and standby database. I have two connections between them. That makes two addresses for the service (servicetostandby) specified in the log_archive_dest used by dataguard. In my case the log_archive_dest Paramater looks like this:
log_archive_dest_3 = 'SERVICE servicetostandby OPTIONAL LGWR SY
NC AFFIRM VALID_FOR=(ONLINE_LO
GFILES,PRIMARY_ROLE) DB_UNIQUE
NAME=standby REOPEN=10 NETTIME
OUT=9'
The tnsnames.ora entry looks like this:
servicetostandby =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = address1)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = address2)(PORT = 1521))
(FAILOVER=true)
(LOAD_BALANCE=false)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = standby)
So if either address1 or address2 is down dataguard should use the other address to connect to the standby database.
Maybe because of the Maximum Availability protection mode the primary database does not perform if the standby database is not available. I'm not sure about that. But fact is that if I power off the standby database, the primary database hangs only for 9 seconds. That's specified in the net_time_out attribut of the log_archive_dest Parameter. So I'm quite sure that something in the oracle net service causes the problem.
With the "primary hangs" I mean: After the used connection (say address1) went down the redologfiles of the primary database get filled and then it stops for 15 minutes. The messages in the alert.log:
Thread 1 cannot allocate new log, sequence 1304
All online logs needed archiving
After 15 minutes the connection via address2 is established and everything works fine.
I hope I made myself clear this time and didn't confuse you totally.

Downloading & installing Oracle 10g

I have Downloaded Oracle 10g about 4 times, when i try 2 install it it gives me error message " Error reading setup initialisation file". How do i overcome this? I am new with Oracle i dont know if the problem is with the "setup file" or with my PC I am running XP sp2 pentium 4 processor 500 MB of Ram, 80 gig hard drive

It looks like your setup disks are corrupt. It
should just start the Oracle Universal Installer.
Before any new attempt to download, verify that the
zip file is correct. If you are using the regular
winzip, you may check the file using the Shift-T
keyword combination, or if you are using zip.exe, you
may verify it with
unzip -T zipfile
Let me know.Sorry 4 taking sometime 2 respond, i was trying 2 redo everything againg, even downloading!!... I checked the file size from oracle site and file sizes that i downloaded they are not equal. My downloads are not in zip files but just the setup file. can this be the problem? also there is a pause during down load. The download starts well then there is a long pause, i dont know why, else everything downloads easily and quickly.

Oracle 10g DB doesn't startup artomaticlly

Oracle 10g (10.2.0.1) DB doesn't startup artomaticlly with the server.
Navigate to the Windows HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE\oracle_home_name , I find the
ORA_SID_AUTOSTART already set to TRUE. In the Windows Service (local) tab , I find the OracleServiceSID
already appear there and the Startup_type already set to AUTOMATIC.
What is the reasons?
Another issue: I open the Windows Task Manager, the ORACLE.EXE process does not appear in the Task Manager.
In fact, the database is running.

Caching configuration (Times Ten - Oracle 10g)

Hi all,
I have managed to setup Times Ten and get a cache group configured against a table in an oracle 10g instance.
That all works so great. My question is how do I define a set of cache groups and get Times Ten to load them in automatically all together. So what I am saying, is I dont want to have to enter these cache group definitions in manually via ttisql command line (as I have done this time).
Could someone please point me in the right direction with this? Also I would like to be able to set TT up such that the cache agent is automatically started. Is this possible?
Thanks,
Dan

Hi Dan,
In the same way that you can create cache groups through a ttIsql script you can also load them from a script using the LOAD CACHE GROUP and REFRESH CACHE GROUP commands.
However, let's remember that TimesTen is a persistent database and so you should not need to re-create the cache groups nor re-load them just becasue you have stopped and started TimesTen. The cache group definitions and data will still be present as they are persistently stored. Also, if you have a READONLY or USERMANAGED cache group using AUTOREFRESH then the changes that occur in oracle are captured and refreshed to the cache group(s) automatically.
As for starting the cache agent 9or the repagent0 automatically, this kind of depends on how you are managing the startup/shutdown of the cache datastore (i.e. what itss ramPolicy is). You can set the cachePolicy for the datastore using ttAdmin as follows:
ttAdmin -cachePolicy always DSNname
this tells TimesTen that the cache agent should always be running for this datastore. However, a side effect of this is that the datastore will allways be loaded in memory when the TimesTen instance is up (i.e. the TimesTen main daemon is running). If you want to be able to start and stop the datastore manually (or from a script) then you will likely be using a ramPolicy of manual and running some script to load/unload the datastore into/from memory. If so then just add the relevant ttadmin -cacheStart|-cacheStop commands to that script.

To me it looks like your undotbs on node3 is filled and not marking old undo as expired. Use this query to find out if it is labeling old undo as expired.
SELECT tablespace_name, status, COUNT(*) AS HOW_MANY
FROM dba_undo_extents
GROUP BY tablespace_name, status;
Another thing I noticed from your alertlog is it is only doing that on undotbs3, which I assumes is on node3.
1) try recreate undotbs on node3
2) take node3 out of service (stop nodeapps, ASM, instance and finally CRS on node3) and see if you can do DML on your database.

Oracle 10g: How to reduce the select * time

Hello,
We have 10 million entries in our database (Oracle 10g in windows 32 bit machine.)
The execution of 'select * ....' takes 3 to 4 hour. Is there any way to reduce this time.
Is any tool available which can read the oracle export data and produce the output in text file format.
or any idea ?
Thanks
With Regards
Hemant.

OK, let me try again. Where is the output being directed? To the screen? To a file?
The reason I ask is that often people will say "It takes n minutes to run this query" when in fact Oracle is producing the result set in a few seconds and what is taking n minutes is to run the results past the screen.
You should take a statspack report while the query is running and see where it is spending its time.

That's a different problem. I assume by "export data" you mean a .dmp file created by exp or expdp? If so what do you hope to achieve by outputting it in text format? What is the business problem to be solved?Answer: Since customer want to read all 10 milion entries. so we are think if we can dump (Oracle export) the data and using some tool (not Oracle) to read the data so there is no wait for the customer.As stated, a dmp file is oracle proprietary binary file that exists solely to transport data across platforms/versions. It is not suitable for your purpose. You are far better off finding where the current query is spending its time than looking for some kludge. 10 million rows of data is still 10 million rows of data. Do you think extracting it from the db, storeing it in some other format, and having some other tool read it off of disk in that format is going to be faster than simply selecting it from the db -- asking the db to do what it was designed to do?

Procedure execution time difference in Oacle 9i and Oracle 10g

Hi,
My procedure is taking time on

EXECUTE IMMEDIATE 'ALTER SESSION SET TIMED_STATISTICS = TRUE';
OPEN cur_list;

so Please guide me how to reduce the time in oracle 10g for procedure?
1) Is this envrionment setting parameter?
2) I have to tune the query? but which is executing fine on oracle 9i?
so how to decrease the execution time?
Thanks in advance.

Insert statement taking time on oracle 10g

Thanks.

According to the execution plan you posted parallelism is not taking place - no parallel operations listed
Check the hint syntax. In particular, "PARALLEL" does not look right.
Running queries in parallel can either help performance, hurt performance, or do nothing for performance. In your case a parallel index scan on MFIPROCESS.INDX_TEMP_CUST_AUTH_PERF_MV using the PARALLEL_INDEX hint and the PARALLEL hint specifying the table for MAT_VIEW MFIPROCESS.TEMP_CUST_AUTH_PERF_MV Cost might help, something like (untested)
select /*+ PARALLEL_INDEX(INDX_TEMP_CST_AUTH_PERF_MV) PARALLEL(TEMP_CUST_AUTHPERF_MV) */Is query rewrite causing the MVs to be read? If so hinting the query will be tricky

Oracle 10g Real Time Backup

Hi
My company need to set database real time backup for Oracle 10g release 2 (Standard Edition).
I see in Oracle Database 10g Product Family [Oracle Database 10g Product Family|http://www.oracle.com/technology/products/database/oracle10g/pdf/twp_general_10gdb_product_family.pdf] not support the Data Guard.
Can I do it in Oracle 10g SE ?
Thanks in advance

hi,
trouble is the cost of EE can be quite expensive
another way of creating a psuedo (hope I spelt that correctly) dataguard would be to script a method of shipping archive files to a DR server.
