Oracle8 and Redhat 6.0

I know that Oracle8 uses an older version of glibc and that it
doesn't work out of the box with RH6.0... Does anybody have a
fix? Maybe installing the old glib RPMs? Can they co-exist
with the new stuff?
Thanx in advance... Eric

I'm sorry if I've missed something obvious, but this seems very
unclear:
Oracle will work on Red Hat Linux 6.0, but you will need to
use the "compat" packages in order to relink Oracle, if you
need to do so. You will need to patch the Oracle Makefiles
to use the correct linker from the "compat" packages in
order to do so. In order to install Oracle on Red Hat Linux
6.0, you will need to choose not to create a database at
install time; wait until after you have relinked Oracle to
create a database.I have been attempting to modify the Oracle Makefiles to use the
linker from the "compat" packages, and have had varying degrees
of success. I still have not been successful in getting 'make -f
ins_rdbms.mk install' to produce any usable binaries though. If
someone who has successfully done this could post a patch or,
even better, more detailed instructions I would be much
apperciative.

Large Data file problem in Oracle 8.1.7 and RedHat 6.2EE

I've installed the RedHat 6.2EE (Enterprise

I've finally solved it!
I downloaded the following jre from blackdown:
jre118_v3-glibc-2.1.3-DYNMOTIF.tar.bz2
It's the only one that seems to work (and god, have I tried them all!)
I've no idea what the DYNMOTIF means (apart from being something to do with Motif - but you don't have to be a linux guru to work that out ;)) - but, hell, it works.
And after sitting in front of this machine for 3 days trying to deal with Oracle's, frankly PATHETIC install, that's so full of holes and bugs, that's all I care about..
The one bundled with Oracle 8.1.7 doesn't work with Linux redhat 6.2EE.
Don't oracle test their software?
Anyway I'm happy now, and I'm leaving this in case anybody else has the same problem.
Thanks for everyone's help.

Performance issues with Oracle EE 9.2.0.4 and RedHat 2.1

Hello,
I am having some serious performance issues with Oracle Enterprise Edition 9.2.0.4 and RedHat Linux 2.1. The processor goes berserk at 100% for long (some 5 min.) periods of time, and all the ram memory gets used.
Some environment characteristics:
Machine: Intel Pentium IV 2.0GHz with 1GB of RAM.
OS: RedHat Linux 2.1 Enterprise.
Oracle: Oracle Enterprise Edition 9.2.0.4
Application: We have a small web-application with 10 users (for now) and very basic queries (all in stored procedures). Also we use the latest version of ODP.NET with default connection settings (some low pooling, etc).
Does anyone know what could be going on?
Is anybody else having this similar behavior?
We change from SQL-Server so we are not the world expert on the matter. But we want a reliable system nonetheless.
Please help us out, gives some tips, tricks, or guides
Thanks to all,
Frank

Thank you very much and sorry I couldnt write sooner. It seems that the administrator doesnt see the kswap going on so much, so I dont really know what is going on.
We are looking at some queries and some indexing but this is nuts, if I had some poor queries, which we dont really, the server would show pick right?
But he goes crazy and has two oracle processes taking all the resources. There seems to be little swapping going on.
Son now what? They are all ready talking about MS-SQL please help me out here, this is crazy!!!
We have, may be the most powerful combinations here. What is oracle doing?
We even kill the Working Process of the IIS and have no one do anything with the database and still dose two processes going on.
Can some one help me?
Thanks,
Frank

Connecting personal oracle8 and dev2000

How to connect personal oracle8 and dev2000

ok, for connecting PO8 to D2k you have to do the same setting as for central database connectivity.
Anyway, here is the solution :
1. Make an entry in tnsname.ora for your PO8 sid.
2. Start the listener by giving the command lsnrctl start on command prompt.
3. Start the database.
4. Check the connectivity through SQL Plus.
5. If sql plus is connected, start forms and connect it from there.
Note : you may need to give po8.world in the connect string, but it is not required most of the time.
where po8.world is the entry in the tnsname.ora.
Best of luck

Personal Oracle8 and Developer6 ?

I've installed Personal Oracle 8.0.3 on my Win98 computer. I
tried to install also Developer6 (required support files 8.0.5c),
but instalation was interrupted because of version conflict
between support files of Dev6 and Personal Oracle8 (I was
installing in one ORACLE_HOME). If I had ignored warning and
continued with instalation of Dev6, I was not able to start
Oracle database after succesfull installation of Dev6. I've got
message: "The Oracle80.exe file is linked to missing export
NZ80.dll:nztpfvec".
I tried to copy NZ80.dll from Oracle distribution to my
Oracle_Home, but database still was not operational.
Is possible to install these products to diffrent Oracle_homes?
Could anyone help me ?

Hi there,
You cannot have Oracle8 and Dev6.0 in the same Oracle home.
Install Dev6.0 in a different Oracle home.
I guess it should solve your problem.

when you download and install the 9i thin driver, the connection pool
can be
configured as,

You cannot use two different OCI drivers at the same time to create
Connection pools in a single server.

Hi,
I dont know exactly what driver we use, but I know that the same driver

The behavior is that connection duo the 9i are rollin back sometimes,
about
30%
of all transactions are rolling back.
Thats why I ve been told to use newer drivers (9i drivers).
So, yes, I see exceptions, roll back exceptions of the transactionsthat
are

But I wonder how to do that, and how can I see exactly what driver

XA : Oracle8 and Oracle9

I using Tuxedo8.0 ..and I need to use XA with both Oracle8 and Oracle9...
This time is using only Oracle8, Two-Phase commit, and next year we have to join
with Oracle9.
Then I would like to know Can I use XA across Oracle8 and Oracle9...
What is RM file for Oracle9?
Regards,
Yos

Hello Yos,
XA transactions can span multiple RDBMSes... There may be limitations/problems
as every RDBMS has a different implementation and hence do not work the same way.
The base rule is: You can definitely have a single XA transaction across Oracle,
Informix and DB2. So, your scenario of XA transactions across Oracle 8 and 9 databases
should work..
For RM file entry, please refer Oracle/Tuxedo documentations. Oracle 8.x RM file
entry may also work fine with Oracle 9.x. Just give it a try.

Srini,
The major features that are in Oracle8i and are not in Oracle8
are the following:
1) Java and internet capabilities are in Oracle8i and these
are not in Oracle8
2) JVM - Java Virtural Machine also known as JServer, this
allows developer to create applications in Java, PL/SQL
or OCI
3) iFS - Internet File System, this allows the database to
store relational and non-relation data files is present
in Oracle8i and this is not in Oracle8.
4) Oracle8i comes with interMedia which allows user to access
multi-media data.
5) Oracle8i comes with WebDB, a web developement environment.
These are the major differences and I hope it helps. For
complete new features, please refer to Oracle8i manual.

Oracle8i On RedHat 7.x Mini How-To

For those of you still struggling with getting Oracle8i to work on RedHat 7.0/7.1 (or any other glibc 2.2 based Linux), here are some simple steps that should get you up and running:
0. Be sure to follow the instructions in the Installation Guide, particularly those in Chapter 2: Pre-Installation.
1. Before running 'runInstaller', unset the LANG environment variable from the Linux shell prompt (ex. unset LANG).
2. Install Oracle as usual, but do NOT create a database or configure Oracle networking (Net8).
3. When prompted to run the 'root.sh' script during installation, stop and fix the bug before proceeding. The line that reads:
RUID=`/usr/bin/id|$AWK -F$ '{print $2}'|$AWK -F$ '{print $1}`
should read
RUID=`/usr/bin/id|$AWK -F$ '{print $2}'|$AWK -F$ '{print $1}'`
(there is a missing single quote in the next to last character of the line).
Insert the missing single quote and then run 'root.sh' as root. Be sure to have the ORACLE_HOME environment variable set.
4. Download the 'glibc-2.1.3-stubs.tar.gz' patch from Technet or from ftp://oracle-ftp.oracle.com/server/patchsets/unix/LINUX/bug1467074 and install according to the README file.
5. Perform this step if you are planning to install Oracle Parallel Server (OPS). Otherwise, skip this step. There is a missing library in the sysliblist that prevents the Oracle kernel from relinking properly if OPS is installed. Edit the $ORACLE_HOME/lib/sysliblist to include '-lnsl', so that '-ldl -lm -lpthread' becomes '-ldl -lm -lnsl -lpthread'. Then relink the Oracle kernel like this:
cd $ORACLE_HOME/rdbms/lib
make -f ins_rdbms.mk install
6. Now configure networking (using netasst or netca) and the database (using dbassist) as usual. Be sure to 'unset LANG' before running these tools.
That's it. I hope this was useful to you.

Hi:
I just spent 12 hours trying to install Oracle 8.1.6.1EE on RH Linux 7.1 and finally got it to work. The problem always arose when the UI started linking the executables. RedHat 7.0/t.1 ships with glibc 2.2. but Oracle compiles with glibc 2.1. So what you have to do is install all of the compat-* RPMS that come with the Linux distro and then enter the following in the shell:
LD_ASSUME_KERNEL=2.2.5
./usr/i386-glibc21-linux/bin/i386-glibc21-linux-env.sh
Then run the Installer from the shell prompt. Also make sure you have set the correct environmental variables in the .bash-profile file belonging to the user that owns the oracle installation. Visit http://jordan.fortwayne.com/oracle/817.html for this information. I got this Oracle distro with the book "Oracle 8i for Linux starter kit" by Steve Bobrowski.

OAS4.0.7, DB8.1.5 and Redhat 6.1

Has anyone succesfully installed Redhat 6.1 with Oracle 8.1.5
(8i) and OAS 4.0.7 on it? I tried but i stranded now that OAS
seems installed. When i want to start the services it seems that
the orb services don't want to start.
From the GUI it mentions an OWS-20214: CORBA orb processes can
not be started... but if i dig a bit deeper the most detailed
info i can actually dig up is from the ORB control utility:
unexpected exception IDL:omg.org/CORBA/COMM_FAILURE:1.0, from
yocorb.c 780.
I looked at the issue some other people with the OWS-20214 error
message had, where the hostname could not be resolved, but that
doesn't seem to be the problem in this case.
Any suggestions?

As far as I knows, OAS 4.0.7 will not work on RH6, you will have
to wait for OAS 4.0.8 for Linux. OAS3 can run on RH6.

Oracle 8.1.7 ProC and RedHat 7.2

I found this answer in Metalink for a similar issue with
Mandrake. Anyhow, I thought I'd pass it on.
Apparently Oracle817 does not ship with a good pcscfg.cfg for
RH 7.2. As a result you need to create one to use with RH 7.2
The order of what lies within the pcscfg.cfg is very
significant. I had first copied the bottom one from Metalink
and although it got me past all of the compile errors
concerning the 'header' files, it still would not work.
This one works (sys_include has to be on one line for real):
sys_include=($ORACLE_HOME/precomp/public,
/usr/include,
/usr/lib/gcc-lib/i386-redhat-linux/egcs-2.91.66/include)
include=($ORACLE_HOME/precomp/public)
include=($ORACLE_HOME/rdbms/demo)
include=($ORACLE_HOME/network/public)
include=($ORACLE_HOME/plsql/public)
include=($ORACLE_HOME/otrace/public)
This one basically causes ProC to eat all available memory and
swap and finally get killed by Linux. This one came from
Metalink as well. Although it is basically the same as the one
above, the order of the directories for 'sys_include' are
different. For my system, this is significant.
sys_include=($ORACLE_HOME/precomp/public,
/usr/lib/gcc-lib/i386-redhat-linux/egcs-2.91.66/include,

I agree with the rest of you folks. JDOM will be your best bet for integration. I am currently using JDOM to parse and/or create xml documents. As mentioned the tutorials are very good to check out. If you just want to hit the JDOM highlights and hit the ground running check out this link. http://www.jdom.org/downloads/docs.html
Take some time to check out the first 3 links on that page. They are JDOM and XML Parsing, Part 1, Part 2, and Part 3. Very good information about JDOM and XML parsing.

SDK 1.4.1 and Redhat 8

Okay then...
I'm running Redhat 8 and Netscape 4.75 and I'd like to run the J2 sdk v1.4.1.
I have it installed and it will happily compile, it will run command line applications. The problem is it won't run applets, or anything with a GUI. They will compile but when it comes to running.....not a chance
I have the plug-in installed on netscape. And am using the 'demo' applets supplied from Sun with the sdk to test this function.
If I try to run the applet one of two things happens.
1) By double clicking in the file manager it launches mozilla (which also has the plug-in) the window comes up with the html presented and an icon on the screen that represents the applet, when I click on the applet I get a error message " This page contains information of a type (applicatio/x-java-vm) that can only be view with the appropriatwe plug-in"
2) I open the file via Netscape ( File -> Open Page -> Choose File etc etc) and the html page pops up with the message " java.lang.ClassFormatError - Bad major version number" along the bottom of the screen.
3) I use the command prompt (java MyApplet) and I get a hole host of errors, mainly to do with class Lang... but others also.... there's too many to metion here...
So then a few questions arise.... why doesn't the plug-in work... and why don't applets work at all??? I use the applets on the java.sun tutorial pages and they come up without a problem.... unless I take the code which doesn't compile and doesn't run... most odd.
Anyway, I'm completely out of ideas and all and any help is greatly appreciated.... HAS ANYONE ELSE EXPERIENCED THIS...
Actually I have sonce removed the SDK and replaced ut with the run time environment, the same thing happens.
Cheers

I got some of my answer in the following web page
http://home.bredband.no/gaulyk/java/tutorial/javaredhat.html
The problem I ran into was when I installed Redhat 8.0 with every
package, the /usr/bin/java is in 1.3.1 and it was not compatiable
with even jdk1.3.1_07, and of course j2sdk1.4.1_02 because
many changes to javax.swing went in.
The about web page suggested to create the file /etc/profile.d/java.sh
to include PATH=/usr/java/j2sdk1.4.1_02/bin:$PATH.
I also installed javax.comm.properties from javax.comm.api
package in /usr/java/j2sdk1.4.1_02/jre/lib directory
to get rid of the run time error from GNU that invokes
java applet.
If anyone is interesting to run applet or web application that
needs special fonts other than Enlish, please download
fonts to /usr/java/j2sdk1.4.1_02/jre/fonts directory.
I just installed some Chinese tru type fonts (.ttf) in that
directory and am able display Chinese character with
given encoding. You have to tell for example JTextArea what
font you want to display and FileInputStream for example
what encoding you want to use in your java code.
In Windows, every thing work right after I downloads the jdk
I do not need to do anything special because my Window 2000
and Window XP already have Chinese fonts I need. I also
use Textpad to code, compile and run my java application and
applet. Textpad is a nice tool on Window environment
that color code Java program key words and you can double
click compiling error and get to the error right away.
Hope this info help.

Oracle8 and Redhat 6.0
