Segmentation Fault when connecting to SQL*Plus from Applications tier
Hi Everyone -
I am currently in the process of upgrading a client from 11.5.10.2 to 12.1.1 (eventually 12.1.3) on a OEL x86-64 server. I have laid down the software stack and followed all of the requirements as per the Installation manuals and 761566.1. I also have an open SR right now on this issue - but I wanted to see if any of you have ever run into the issue that I am encountering.
When I try to run adadmin/adpatch - I get to the prompt of providing the system user password and the utility simply exits. No errors in adpatch.log or adadmin.log (both are 0 bytes in size).
When I try to connect using SQL*Plus from the applications tier using either:
sqlplus apps/****@SID
sqlplus system/****@SID
I get a Segmentation Fault error. There are also no errors in my alert log file on the database tier. I found this error while attempting to apply the upgrade merge patch.
Has anyone ever seen s Segmentation Fault error? I have search MOS, found a couple of potential solutions - but nothing has solved the issue so far.
Thanks in advance...

Are you on 11.1.0.5.0? Is this the database version?
No, my database tier is 11.2.0.3 (the database version displayed above was the client version running on the Application Tier.
Who is the owner of the application tier files? If it is applmgr user, please make sure you login as that user and source the application env file before running sqlplus -- Please issue "echo $ORACLE_HOME" and "which sqlplus" and post the output here.
My owner of the application tier is oracle. I have sourced the environment using $APPL_TOP/APPSR12Dev1_******.env

Segmentation fault when calling dbms_alert.register() procedure from OCCI
I am trying to call the dbms_alert.register() from the OCCI but I get segmentation fault when I run the program, here is the code snippet. I am gettin segmentation fault immediately after calling setSQL() method.
Environment *occiEnvironment_;
Connection *occiConnection_ ;
string userName("SCOTT");
string userPasswd("tiger");
string url("");
occiEnvironment_ = Environment::createEnvironment();
try{
occiConnection_ = occiEnvironment_->createConnection(userName,userPasswd,url);
Statement *occiStatement1;
cout << "Before setSQL" << endl;
occiStatement1->setSQL("BEGIN dbms_alert.register(:1); END;");
cout << "After setSQL" << endl;
string alert1("MY_ALERT");
occiStatement1->setString(1,alert1);
occiStatement1->execute();
catch (SQLException ea)
cout << ea.what();
}Thanks for the reply, now I dont see segmentation fault.
I tried to exted the code further to wait for the registered events, I added the following code, I do get and event but then get the exception:
Statement *occiStatement1 = occiConnection_->createStatement();
Statement *occiStatement2 = occiConnection_->createStatement();
string alert, msg;
int status;
occiStatement1->setSQL("BEGIN dbms_alert.register(:1); END;");
string alert1("MY_ALERT");
occiStatement1->setString(1,alert1);
occiStatement1->execute();
occiStatement2->setSQL("BEGIN dbms_alert.waitany(:alert,:msg,:status); END;");
occiStatement2->registerOutParam(1, OCCICHAR, sizeof(alert));

Error when connecting to SQL*PLUS via ODBC to Excel
OS: Windows 2000 Professional
Oracle DB: 9i release 2
SQL*Plus: Release 9.2.0.1.0
MS Excel: 2000
===================
When I try to connect to SQL*PLUS via ODBC to Excel with "connect scott/tiger@odbc:libro" I get the following error:
ORA-03121: no interface driver connected - function not performedSQL Server objects are commonly case sensitive, so please surround the column and table names by double quotes:
SELECT "Type_PK_ID" FROM "dbo"."boundaries"@sqlserver
SIDE NOTE: Oracle is by default not case sensitive and all object names are stored in upper case. To get case sensitive objects they need to be surrounded by double quotes. In HSODBC case sensitive table names were commonly found even when not surrounded by double quotes as the gateway used internal SQL Server methods to find the correct table nameing - this method does not work for column names. So to be able to query a case sensitive column it needs to be surrounded by double quotes and the table name must be written as stored in the source database. -
Failure when connecting MS SQL SERVER from ODI ! could not load JDBS driver
i have some trouble with connecting MS SQL SERVER from ODI.
I have already downland jdbs driver 3.0 (and 2.0 ) and copy the sqljdbc4.jar to D:\oracle\product\11.1.1\Oracle_ODI_1\oracledi\agent\drivers( where the oracle jdbs driver is already exitst )....but i have this error :
could not load JDBS driver class..
thanksAfter more investigation and even more chocolate, we've identified the problem and it's now working. For anyone else who strikes this problem in future, here's something to check/consider/try:
Even though Squirrel SQL Client was connecting and working ok using the MS JDBC driver (v 3.0), it recorded this in its logs:
Cannot resolve the collation conflict between "SQL_Latin1_General_CP1_CI_AS" and "Latin1_General_CI_AS" in the INTERSECT operation.
We've found that the open source jTDS driver does not have the same issue as the Microsoft one.
We've installed the current jTDS driver, recorded the driver name (net.sourceforge.jtds.jdbc.Driver) and the JDBC URL (jdbc:jtds:sqlserver://<hostname>:1433/<database>) and the connection is now working fine.
Hope this helps other people...
Thanks to those of you who offered suggestions and things to check...much appreciated.

#names.default_domain = world
#Syntax: domain-name
#Default: NULL
# Indicates the domain from which the client most often requests names. When
# this parameter is set the default domain name (for example, US.ACME), the
# domain name will be automatically appended to any unqualified name in an
# ONAmes request (query, register, deregister, etc). Any name which contains
# an unescaped dot ('.') will not have the default domain appended. Simple
# names may be qualified with a trailing dot (for example 'rootserver.').
#names.initial_retry_timeout = 30
#Syntax: 1-600 seconds
#Default: 15 (OSD)
# Determines how long a client will wait for a response from a Names Server
# before reiterating the request to the next server in the preferred_servers
# list.
#names.max_open_connections = 3
#Syntax: 3-64
#Default: ADDRS in preferred_servers
# Determines how many connections an ONames client may have open at one time.
# Clients will ordinarily keep connections to servers open once they are
# established until the operation (or session in namesctl) is complete. A
# connection will be opened whenever needed, and if the maximum would be
# exceeded the least recently used connection will be closed.
#names.message_pool_start_size = 10
#Syntax: 3-256
#Default: 10
# Determines the initial number of messages allocated in the client's message
# pool. This pool provides the client with pre-allocated messages to be used
# for requests to ONames servers. Messages which are in the pool and unused
# may be reused. If a message is needed and no free messages are available in
# the pool more will be allocated.
#names.preferred_servers = (address_list =
# (address=(protocol=ipc)(key=n23))
# (address=(protocol=tcp)(host=nineva)(port=1383))
# (address=(protocol=tcp)(host=cicada)(port=1575))
#Syntax: ADDR_LIST
#Default: Well-Known (OSD)
# Specifies a list of ONames servers in the client's region; requests will be
# sent to each ADDRESS in the list until a response is recieved, or the list
# (and number of retries) is exhausted.
# Addresses of the following form specify that messages to the ONames server

#names.directory_path
#Syntax: <adapter-name>
#Default: TNSNAMES,ONAMES,HOSTNAME
# Sets the (ordered) list of naming adaptors to use in resolving a name.
# The default is as shown for 3.0.2 of sqlnet onwards. The default was
# (TNSNAMES, ONAMES) before that. The value can be presented without
# parentheses if only a single entry is being specified. The parameter is
# recognized from version 2.3.2 of sqlnet onward. Acceptable values include:
# TNSNAMES -- tnsnames.ora lookup
# ONAMES -- Oracle Names
# HOSTNAME -- use the hostname (or an alias of the hostname)
# NIS -- NIS (also known as "yp")
# CDS -- OSF DCE's Cell Directory Service
# NDS -- Novell's Netware Directory Service
# - Client Cache (ONRSD) ---------------------------------------------
names.addresses = (ADDRESS=(PROTOCOL=IPC)(KEY=ONAMES))
Syntax: ADDR
Default: (ADDRESS=(PROTOCOL=IPC)(KEY=ONAMES))
Address on which the client cache listens (is available to clients).
Any valid TNS address is allowed. The default should be used if at
all possible; clients have this entry hardwired as the first line
of their server-list file (sdns.ora). If the address is set to a
non-default value the client's preferred_servers parameter should
be set to include the client-cache address first.
names.authority_required = False
Syntax: T/F
Default: False
Determines whether system querys (for the root etc) require Authoritative
answers.
names.auto_refresh_expire = 259200
Syntax: Number of seconds, 60-1209600
Default: 259200
This is the amount of time (in seconds) the server will cache the addresses
of servers listed in server-list file (sdns.ora). When this time expires the
server will issue another query to the servers in those regions to refresh
the data.
names.auto_refresh_retry = 180
Syntax: Number of seconds, 60-3600
Default: sec. 180
This set how often the server will retry when the auto_refresh query fails.
names.cache_checkpoint_file = cache.ckp
Syntax: filename
Default: $ORACLE_HOME/network/names/ckpcch.ora
Specifies the name of the operating system file to which the Names Server
writes its foreign data cache.
names.cache_checkpoint_interval = 7200
Syntax: Number of seconds, 10-259200
Default: 0 (off)
Indicates the interval at which a Names Server writes a checkpoint of its
data cache to the checkpoint file.
names.default_forwarders=
(FORWARDER_LIST=
(FORWARDER=
(NAME= rootserv1.world)
(ADDRESS=(PROTOCOL=tcp)(PORT=42100)(HOST=roothost))))
Syntax: Name-Value/address_list
Default: NULL
A list (in NV form) of the addresses of other servers which should be used to
forward querys while in default_forwarder (slave) mode. NAME is the global
names for the server to which forwards whould be directed, and ADDRESS is its
address.
names.default_forwarders_only = True
Syntax: T/F
Default: False
When set to true this server will use the servers listed in default_forwarders
to forward all operations which involve data in foreign regions. Otherwise it
will use the servers defined in the server-list file (sdns.ora) in addition
to any defined in the default_forwarders parameter.
names.log_directory = /oracle/network/log
Syntax: directory
Default: $ORACLE_HOME/network/log
Indicates the name of the directory where the log file for Names Server
operational events are written.
names.log_file = names.log
Syntax: filename
Default: names.log
The name of the output file to which Names Server operational events are
written.
names.log_stats_interval = 3600
Syntax: Number of seconds, 10-ub4max
Default: sec. 0 (off)
Specifies the number of seconds between statistical entries in log file.
names.log_unique = False
Syntax: T/F
Default: False
If set to true the server will guarantee that the log file will have a unique
name which will not overwrite any existing files (note that log files are
appended to, so log information will not be lost if log_unique is not true).
names.max_open_connections = 10
Syntax: 3-64
Default: 10
Specifies the number of connections that the Names Server can have open at any
given time. The value is generated as the value 10 or the sum of one
connection for listening, five for clients, plus one for each foreign domain
defined in the local administrative region, whichever is greater. Any
operation which requires the server to open a network connection will use
an already open connection if it is available, or will open a connection
if not. Higher settings will save time and cost network resources; lower
settings save network resources, cost time.
names.max_reforwards = 2
Syntax: 1-15
Default: 2
The maximum number of times the server will attempt to forward a certain
operation.
names.message_pool_start_size = 24
Syntax: 3-256
Default: 10
Determines the initial number of messages allocated in the server's message
pool. This pool provides the server with pre-allocated messages to be used
for incoming or outgoing messages (forwards). Messages which are in the pool
and unused may be reused. If a message is needed and no free messages are
available in the pool more will be allocated.
names.no_modify_requests = False
Syntax: T/F
Default: False
If set to true, the server will refuse any operations which modify the
data in its region (it will still save foreign info in the cache which is
returned from foreign querys).
names.password = 625926683431AA55
Syntax: encrypted string
Default: NULL
If set the server will require that the user provide a password in his
namesctl session (either with sqlnet.ora:namesctl.server_password or 'set
password') in order to do 'sensitive' operations, like stop, restart, reload.
This parameter is generally set in encrypted form, so it can not be set
manually.
names.reset_stats_interval = 3600
Syntax: 10-ub4max
Default: 0 (off)
Specifies the number of seconds during which the statistics collected by the
Names Servers should accumulate. At the frequency specified, they are reset
to zero. The default value of 0 means never reset statistics.
names.trace_directory = /oracle/network/trace
Syntax: directory
Default: $ORACLE_HOME/network/trace
Indicates the name of the directory to which trace files from a Names Server
trace session are written.
names.trace_file = names.trc
Syntax: filename

Syntax: list of numbers
Default: NULL
Internal mechanism to control trace behavior.
names.trace_unique = True
Syntax: T/F
Default: False
Indicates whether each trace file has a unique name, allowing multiple trace
files to coexist. If the value is set to ON, a process identifier is appended
to the name of each trace file generated.
# - Namesctl ---------------------------------------------------------

#Default: False
# If set to TRUE namesctl will suppress any error messages when namesctl is
# unable to connect to a default names server.
#namesctl.internal_use = True
#Syntax: T/F
#Default: False
# If set to true namesctl will enable a set of internal undocumented commands.

No suitable driver when connect MS SQL server from Oracle 10g using JTDS
Hi,
I have developed a java servlet application connection to MS SQL using jtds-1.2.jar. I have try to deploy this application to Oracle 9ias and it works fine.
However, when I deploy the same application to Oracle 10g (10.1.2.0.2), I encounter this error - java.sql.SQLException: No suitable driver.
I have copy the jtds-1.2.jar to Ora10g/jdbc/lib, Ora10g/j2ee/home/lib and also the Ora10g/j233/OC$J_GENERAL/applications/sampleApp/sampleApp/WEB-INF/lib folder, and also setup the data source via the EM interface. The data-source.xml entry is as follows:
<data-source location="jdbc/ess" class="com.evermind.sql.DriverManagerDataSource" xa-location="jdbc/xa/essS" ejb-location="jdbc/ess" connection-driver="net.sourceforge.jtds.jdbc.Driver" username="scott" url="jdbc:jtds:sqlserver://202.xx.xx.xx:1433/sampleDB" inactivity-timeout="30" name="ess"/>
</data-sources>
Is there any configuration that I've forgotten to set?>

Which I believe from what you have entered is:
Ora10g/j2ee/OC4J_GENERAL/applib
There's a general JDBC 3rd party driver set of documentation here:
http://download.oracle.com/docs/cd/B14099_11/web.1012/b14012/datasrc.htm#sthref592
This is not using jtds-1.2.jar but it shows how another set of 3rd party jdbc libs are used with the server.

Connect via SQL*Plus taking more time in Oracle 11 than in 10

NLSRTL Version 10.2.0.4.0 - ProductionOS is AIX 5.3 for Oracle 10 and AIX 6.1 for Oracle 11.
We are currently in the process of migrating some applications from Oracle 10 to 11. Our admins have setup a new development system for us with an Oracle 11 instance. Regarding performance the new system behaves more or less the same than our old, e.g. when executing SQLs we notice hardly any performance differences and those we find are slightly in favour of the new system.
But now we discovered that the time it takes to establish a database connection via SQL*Plus is longer on the Oracle 11 system. Running the following code
sqlplus -s user/pw@database <<END
quit
ENDa thousand times takes ~60s under Oracle 10 but ~140s under Oracle 11. This may not seem much but we are running a test framework consisting of a bunch of shell scripts where several thousand connections are openend via SQL*Plus to execute some SQLs, so that even this small time difference results in rather huge difference in total runtime. The SQLs themself require roughly the same time in both databases, as already mentioned above they are in fact slightly faster in Oracle 11.
To analyze the time difference I ran a trace for the connect with the following parameters in sqlnet.ora
TRACE_LEVEL_CLIENT=4
TRACE_UNIQUE_CLIENT=ONand found out that there is a time difference of about 70ms during the connect handshake:

(1) [22-MAR-2013 13:33:40:618] nscon: got NSPTRS packetAny ideas what could be the reason for this time difference? Something in our network configuration or something else?With local connections - I do not think a TCP packet send from an IP to the same IP, leaves the interface as an actual wire protocol/signal. If I'm correct, then running local connection tests will be mostly useless in checking the actual network infrastructure.
Tests 3 and 4 should be showing the same connection times as the same physical network infrastructure is used - only the direction is reversed in the tests.
I would assume that port settings on the switches and interface settings on the routers treat packets equally in both directions between 2 servers. But this could in part explain the problem if this is not the case. In a case of a router for example, the 1st test's ingress interface is the egress interface of the 2nd test (and vice versa). Configurations can differ substantially between interfaces on the same router. Likewise if there is a firewall - as different rule sets are applied in each test and these rule sets could differ.
So I would not be too quick to state that this is definitely not a network problem. But I agree that based on the small percentage difference (assuming comparable tests), it does not look like a network issue.
The next step is to determine what the delay is between the listener accepting the client connection, and the connection being serviced by a dedicated server process.
This will require listener tracing - tracing the time from when the listener accepted the connection (and parsed the TNS connection string), to handing off the connection to the dedicated server process.
As a comparison test, you can also test shared server connections. Dispatcher processes (of the db instance) register themselves with the listener. The shared server client hand off is thus done to an existing server process - no need for the Listener to make a kernel call to load and initialise an executable image.
Shared connections are typically faster than dedicated connections in this respect.
If there is a major time difference, then it means some kind of issue with the listener dealing with dedicated servers as oppose to dispatcher hand off's. As both connections would have had very similar network transit time - which means the connection time difference is related directly to dealing with a dedicated server connection request and hand off.
You can also substitute the oracle executable with a wrapper - and troubleshoot the actual dedicated server startup. I've only done this with Oracle XE 10.2 though and with local IPC connections. Unsure how robust this will be for testing purposes via TCP using 11g. -
TNSPING failure and but surprising connecting through SQL*PLUS
I have Oracle 9i and Oracle 10g express edition installed on my local machine.But since in the path i specified path of Oracle10g first so always tnsnames.ora got picked up from Oracl10g directory which is
C:\softwares\oraclexe\app\oracle\product\10.2.0\server\network\admin\sqlnet.ora
Following are the contents of my sqlnet.ora :--->
SQLNET.AUTHENTICATION_SERVICES = (NTS)

Now when i am doing tnsping to this i got the error as:

But when i connect through Oracle 9i client(SQL*Plus) like peter/devworks@CCTD91, then i am able to connect successfully to Oracle 11g.
Could someone let me know why TNSPING is failing for this and then still why i am able to connect thru SQL*PLUS using the name defined in TNSNAMES.ORA. ?sqlnet.ora is having just one line:

I tried by adding another line: NAMES.DIRECTORY_PATH=(TNSNAMES) but did not make any difference so i removed.

ERROR:
ORA-12560: TNS:protocol adapter error
I do have the entry in TNSNAMES.ORA
XE =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = VANDERBI-M8R870)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = XE)
any ideas?The TNS-12154 (ORA-12154) error appears when SQL*Net cannot find the alias specified for a connection in the TNSNAMES.ORA file or other naming adapter.
Since we can clearly see the XE entry in your TNSNAMES.ORA file from your further post, the message implies that you are not using the TNSNAMES.ORA that contains the entry, or something is changing the lookup so the entry is not found.
Using a different TNSNAMES.ORA can occur under the following situations:
1) You have a TNS_ADMIN environment variable or registry entry that points somewhere other than this TNSNAMES.ORA
2) You are on Windows NT and are using a SQLPLus that is in a different ORACLE_HOME. The WIndows environment forces the use of the networking subsystem in the ORACLE_HOME as the client program (such as SQLPLUS), which defaults to the TNSNAMES.ORA in the home as the client.
Things I would check:
- is there another TNSNAMES.ORA anywhere on the system
- is there a system environment variable called TNS_ADMIN, or is that string found in the registry
- is there possibly a second SQLPlus.exe (even on a networked drive) that migt be called before the XE - supplied SQLPLUS
It is also possible to have a SQLNET.ORA impacting the way TNSNAMES.ORA is used. If all else checks out, we should look at the %ORACLE_HOME%\network\admin\sqlnet.ora in detail as well.
By the way, the Oracle Network Administration docco has two whole chapters devoted to troubleshooting networking issues, from initial config through data errors in the various config files.

XE: Cant connect to sql*plus, APEX seems to function
Hi! I am a beginner in oracle.
I installed oracle XE 10g, both the server and the client on mandriva linux, using the supplied RPM's. After that I ran /etc/init.d/xe/configure and accepted the default values. Then I performed the post-installation steps as mentioned in APEX insstallation guide (sourcing the shell scripts).
In the APEX interface I can see the database, its staistics and I created a user. But when I try to connect using sql*plus, the connection is refused:
SQL> conn sys as sysdba
Enter password:
ERROR:
ORA-12545: Connect failed because target host or object does not exist
Judging from the output of commands below, there is something missing. Any ideas?

Message 1052 not found; No message file for product=network, facility=TNSThe messages tell me that you do not have the ORACLE_HOME variable set correctly. This has been discussed umpteen times, but since search is beyond the call of duty, I'll copy/paste one of my recent responses
In Linux and Unix Oracle REQUIRES that variables ORACLE_HOME and ORACLE_SID be set properly. And *nix REQUIRES that an executable be in the PATH or explicitly referenced. The easiest way of setting those consistently and correctly is to source the oraenv routine which is placed in /usr/local/bin by the installer. To use that, and assuming you are using Linux,
1) Find out the ORACLE_SID for your reference
tail /etc/oratab
and note the last line. The first field will be the SID.
2) Source oraenv
. oraenv
[ oracle ]?: enter the SID here
and if you want to put this into a script, enter something like
ORAENV_ASK=NO
ORACLE_SID={enter your SID ehere}
. oraenv
ORAENV_ASK=
Many people will suggest you set these variables in your profile. In the long term that is a bad idea (and DBAs should always be thinking in the long term) since most DBAs end up with a second database, ORACLE_HOME, upgrade or product and oraenv ensures that there will be no conflicts. -
ORA-03106 Error when connecting to Oracle 10g from Forms 6i
I have migrated my database from Oracle 8.0.5 to Oracle 10g, version 10.0.1.0.3 through import-export utility. During migration, one difference I made was to change the NLS_LANG to UTF8 from ANSI.
The NLS_LANG for client is AMERICAN_AMERICA.WE81S08859P1.
I am using HP ML370 Proliant Server and running Red Hat Enterprise Linux AS version 3 with Oracle 10g
My client-server application is based on Oracle Developer version 2.1. I am using forms 5.0 and reports 3.0 only.
The problem with me is that the client-server application is working against the upgraded database, but with greatly downgraded speed. The .fmb files cannot be compiled, however some of the .rdf files are compiled successfully, but remaining not.
My question is that is Developer 2000 (Forms 5.0.6 and Reports 3.0.5) compatable with Oracle 10 database, as my application is running very slow ?
I tried Forms 6i to remove this problem. I used Forms Developer 6i Recut version and successfully installed on Windows XP, however, when try to create connection using Net 8 Easy Utility, the connection does not establish with following error:
ORA-03106 : fatal two-task communication protocol error
The entry has been checked in tnsnames.ora and is found correct. I also tried connecting through SQL, but the application closes.
The patch set 17 for installation on Windows XP has also been applied, but still the same error persits.
The same installation has also been checked on Windows 2000, but the same problem persists.
I would be thankful if any one provide me solution for the same. Where I am mistaken and what do I do to get out of this problem.
Regards
Naveen.Naveen,
Forms 5.0 is not certified and not tested with Oracle DB 10g because it was desupported before 10g got released.
The other problem is hard to give a generic answer for and I suggest to address this to metalink.oracle.com

How to connect to SQL Server from Forms 10g?
Hello all,
How do we connect to SQL Server database from Forms 10g?
In Oracle Metalink site they have suggested using Transparent Gateway for SQL Server as a solution.
But is there a way we can connect directly to SQL Server from Forms using an ODBC connection
without installing anything on the database server?
Pls help!
Regards,
SamHello all,
I was able to connect to SQL Server from Oracle using Generic Connectivity (HSODBC).
Transparent gateway was not required.
Followed metalink note 109730.1
So, after I created a dblink to SQL Server, I created a synonym for the dblinked SQL Server table.
When I used the synonym as the table source in Oracle Forms, I got the following error while querying.
"ORA-02070 - ROWID is not supported in this context."
This is because Forms has an invisible ROWID field and when data is fetched from SQL Server table
no Rowid is fetched since SQL Server table doesn't have one.
Is there a way to overcome this issue or do we have populate the block manually using a SQL query ?
Pls suggest.
Regards,
Sam -
Segmentation fault when using snapshot isolation with Berkeley DB 6.1.19 and 5.1.29
Hello,
I have been experimenting with snapshot isolation with Berkeley DB, but I find that it frequently triggers a segmentation fault when write transactions are in progress. The following test program reliably demonstrates the problem in Linux using either 5.1.29 or 6.1.19.
https://anl.app.box.com/s/3qq2yiij2676cg3vkgik
Compilation instructions are at the top of the file. The test program creates a temporary directory in /tmp, opens a new environment with the DB_MULTIVERSION flag, and spawns 8 threads. Each thread performs 100 transactional put operations using DB_TXN_SNAPSHOT. The stack trace when the program crashes generally looks like this:
Program received signal SIGSEGV, Segmentation fault.

I understand that this test program, with 8 concurrent (and deliberately conflicting) writers, is not an ideal use case for snapshot isolation, but this can be triggered in other scenarios as well.
You can disable snapshot isolation by toggling the value of the USE_SNAP #define near the top of the source, and the test program then runs fine without it.
Can someone help me to identify the problem?
many thanks,
-PhilHi Phil,
We have taken a look at this in more detail and there was a bug in the code. We have fixed the bug. We will roll it into our next 6.1 release that we do. If you would like an early patch that will go on top of 6.1.19, please email me at [email protected], reference this forum post and I can get a patch sent out to you. It will be a .diff file that apply on the source code and then rebuild the library. Once again thanks for finding the issue, and providing a great test program which tremendously helped in getting this resolved.
thanks

Good afternoon. I have a strange issue when I try to connect to SQL*PLUS, Designer and Discoverer too, with an id other than SYSTEM or SYS. I have 10G database installed on my local PC, with the 10G client, Developer Suite with Discoverer and Designer. I connected in the command window with SYS to create the Designer repository and everything worked fine. I can CONNECT to SQL*PLUS to my local db with the SYSTEM id, but not with my own id. I can't connect to Designer repository with the REPOS_MANAGER id either. It looks as if it is trying to connect, but I get an hour glass and a NOT RESPONDING in the Windows task list. I have checked the id's by logging on to SQL*PLUS with SYSTEM id, and they are set up correctly. Any thoughts or suggestions? I can connect to my local database through GUI tools like TOAD or SQL*Tools using my own id. I would greatly appreciate any ideas you might have. Thanks. DLD
Hi D Moran,
You don't mention the platform and/or Oracle versions you work with, but generally speaking, did you check:
- the tns service (windows) is started?
- did you wait for a moment after the database service started, so that it had the time to "announce itself" to the tns service?
- do you have only one tnsnames.ora file? if more then one: did you select the corresponding oracle home?
etc...
Maybe some of these checks help!
Regards,
Sabine
