Hi,
I've written a simple PingDB program which gives the exception given below:
java.sql.SQLException: Io exception: SO Exception was generated
The code written is :
Class.forName("oracle.jdbc.driver.OracleDriver");
conn = DriverManager.getConnection("jdbc:oracle:thin:@(PMASTI.WORLD=(DESCRIPTION=(SDU=32768)(enable=broken)(LOAD_BALANCE=yes)(ADDRESS=(PROTOCOL = TCP)(HOST=<name_of_primary_host>)(PORT=1525))" +
"(ADDRESS=(PROTOCOL=TCP)(HOST=<name_of_sec_host>)(PORT=1525))(CONNECT_DATA=(SERVICE_NAME=PMASTI))))", uname, passwd);
Any solutions?
Thanks in advance...
regards...

Here is the complete stack trace I'm getting from the code...
java.sql.SQLException: Io exception: SO Exception was generated
at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:134)
at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:179)

at java.sql.DriverManager.getConnection(Unknown Source)
at java.sql.DriverManager.getConnection(Unknown Source)
at com.pkg.productfinder.core.PingDB.main(PingDB.java:14)
where Line 14 in PingDB is the code I've posted above...
I do not have any other logs from oracle side as it's the dedicated server...
Thanks for your reply...
Regards

Ok.... Here I go again...
Finally I solved the issue: Instead of using the connection URL given above I've used the Service Format. Like, ("jdbc:oracle:thin:@//" + pmHost + ":1525" + "/" + dbName, userName, password).
But, I've few query regarding this:
1> When should I go for SID format and when should I go for Service Format? Because, now I've two hosts out of which one works with SID format and other one works with Service format.
2> As you can see above, the URL uses load balancing, providing just one of the two servers in the URL(the Service Format URL) am I be benefited with load balancing? If no, how can I take the advantage of it using Service Format?
3> Sometimes, my host gives me this: ORA-00257: archiver error. Connect internal only, until freed. What does this mean? and how can I solve this?
Hope I'm clear this time.
Regards.

3/
ORA-00257: archiver error. Connect internal only, until freed.
*Cause: The archiver process received an error while trying to archive
a redo log. If the problem is not resolved soon, the database
will stop executing transactions. The most likely cause of this
message is the destination device is out of space to store the
redo log file.
*Action: Check archiver trace file for a detailed description
of the problem. Also verify that the
device specified in the initialization parameter
ARCHIVE_LOG_DEST is set up properly for archiving.
Regards
Michel
