Precompilers, OCI & OCCI :: PRO*C Compiler Version Versus Database Version
Oct 15, 2010
We are planning to upgrade a database from 9.2.0.8.0 to 10.2.0.4.0.We have a lot a PRO*C programs pre compiled using 9.2.0.8.0 (and most likely even 9.2.0.7.0) compiler.
if we could upgrade the database without having to re-compile all the programs.We have tested this approach against some of our programs. Most of them executed fine - but in 2 cases we are getting "ORA-01001 invalid cursor". I suspect, that the case is that Pre compiler version 9 is not supported against 10g databases - but I am not sure.
Would it be a better option to upgrade Pre compiler/client as the first step and the db as the second step (and would that be supported) ? We definitely don't want to upgrade both Pre compiler/Client and the Database in one goal - that would be too risky.

I am trying to upgrade the database 32bit from 10.2.0.1 to 10.2.0.4 version in Linux 32 bit . I faced the version incompatibility error during patch set installation and hence ran the patchset installation with -ignoresysprereqs option.
Now during the patchset installation i encountered the below error in in the install logfile.

connecting to an oracle db with the instant client 11.01.06. I can connect to the db via other tools like sqldbx or SqlTools 1.5 which are also using oci. So now I tried it with c++ using Visual Studio 2005 SP1.
First I tried this
Environment* env=Environment::createEnvironment(Environment::DEFAULT);
Connection* con=NULL;
try{
con=env->createConnection("user","pwd","//servername:ip/mydb");
}
and got following error: "the attribute OCI_ATTR_USERNAME is greater than the maximum allowable length of 255".
So I tried:
Environment* env=Environment::createEnvironment(Environment::DEFAULT);
Connection* con=NULL;
try{
con=env->createConnection("user","pwd","tnsservice-name");
}
where tnsservice-name is the name I specified in the tnsnams.ora, and which I used with the other tools working fine -> same error.My username is only 4 long, so I thought it might have something to do with the string. So I tried:
Environment* env=Environment::createEnvironment(Environment::DEFAULT);
Connection* con=NULL;
string user="user";
string passwd="pwd";
string db="tnsservice-name";
try{
con=env->createConnection(user,passwd,db);
AfxMessageBox("sucess");
}
now it returned the error "TNS:connect descriptor too long". Can't have anything to do with the .ora file, since it worked fine for the other tools. Plus it didn't matter if I renamed the .ora file or removed it from the TNS_ADMIN directory..So I searched a little more for a solution and so an example, where the the last argument is missing. So I tried
string user="user";
string pwd="pwd";
Environment* env=Environment::createEnvironment(Environment::DEFAULT);
Connection* con=NULL;
try{
con=env->createConnection(user,pwd);
}
It returns: "TNS: protocol Adapter error" which I somehow can understand, since the adapter doesn't know to wich db to connect.I also tried to use some frameworks like soci or otl but was never able to compile them... (link errors, unknown data types etc...).

I have four Oracle 8i databases that can not be removed because of client requirements. These 8i databases have there own RMAN catalog which is 10G (Originally there were Oracle 8i, 9i and 10g databases using it but are now moved to 11g catalog). Databases are backing up fine. However, all the other databases are using the RMAN 11g Catalog. I want to point the Oracle 8i databases to point to the RMAN 11g recovery catalog. I created an 8i schema, however, i'm getting the following error message: RMAN-06429: RCVCAT database is not compatible with this version of RMAN. however, I wanted to put the question out there to see if there are any work arounds.

Previously we had 32 bit C++. Now, we have migrated it to 64 bit. And our C++ programs interact with Oracle 10g DB.Our C++ program was working fine with 32 bit. But once after we migrate to 64 bit we are facing problem with one program which does FETCH(EXEC SQL FETCH SUBP1 INTO :new TabRec;) from Oracle DB. ie, We exit from a for loop in the C++ program when we get NOT FOUND(sqlca.sqlcode=1403) on executing the FETCH statement.
The sqlcode generated for NOT FOUND scenario is 1403. But, once after moving to 64 bit C++, we do not see the sqlcode 1403 instead we are seeing a different code 7124089117159473.
As the sqlcode is not 1403, our program does not exit from the for loop and goes on an infinite loop.Am I missing anything that makes me to not get the exact sqlcode?

I am using Pro*C/C++ Release 10.2.0.2 in HP-UX. But Pro*C/C++ application was written long back during oracle release 8. Now we are facing a problem like EXEC SELECT query is not fetching the records even though record is present in DATABASE.
This is not happening every time. This problem starts happening only after heavy use of the unix process.
For every request, unix process will fetch the record and updates the same at the end and process goes to wait mode to get the request again. Let say after 50 request, process is returned with no rows found error.
It started working fine only after restarting the process and problem starts again after 50th or 60th request. This problem we are facing only after upgrade to 10g.

We are migrating a proc application as described below.
Old Env: UNIX
Old DB: Oracle 8i
New Env: Linux
New DB: Oracle 11g
New modules are successfully compiled in Linux environment. But we are facing issues in writing the output of VARCHAR datatype to a file.
find below the extract of code.
EXEC SQL BEGIN DECLARE SECTION;
varchar mcolmnvarchar[4];
EXEC SQL END DECLARE SECTION;
EXEC SQL DECLARE crs CURSOR FOR
SELECT NVL(colmn,' ') FROM table1
memset(mcolmnvarchar.arr,'�',4); //Was added for only Linux migration. Not present in unix env.
EXEC SQL FETCH c1 INTO :mcolmnvarchar;
cout << "Data at Stage one"<< mcolmnvarchar << endl;
mcolmnvarchar.arr[mcolmnvarchar.len]='�';
cout << "Data at Stage two"<< mcolmnvarchar << endl;
fprintf(fptr,"%-4s",mcolmnvarchar.arr);
Above code works absolutely fine in Unix env with Oracle 8i. But with Linux env & Oracle 11g it is not working. No compilation or run time errors. Data at Stage one prints the output of database properly. But after null terminator code, Data at Stage two statement prints without any value. Value is lost after null terminator code.
