Oracle 9i & 10g replicated to MSSQL 2005 Enterprise: Problem !

Question

Hi,
I have been doing some oracle 9i and 10g Replication to MSSQL 2005 Enterprise Database using the SQL 2005 Server Enterprise replication tool. This is working great, however, we recentrly had some problems on the Oracle side getting errors on new connection for both 9i and 10g servers. Only restarting the server has solved the problem so far....
The complete procedure to to this setup is available on Microsoft Technet:
http://www.microsoft.com/technet/prodtechnol/sql/2005/technologies/repl_quickstart_for_oracle.mspx
If anyone could help me regarding the problem on new connections problem I would appreciate
Here are the errors we are getting:
10g Agent connection Error on the Database 10g:
Timestamp=Jul 4, 2008 2:29:03 PM EDT
Severity=Critical
Message=Failed to connect to database instance: ORA-12518: TNS:listener could not hand off client connection (DBD ERROR: OCIServerAttach).
10g Agent connection Error on the Database 9i:
Timestamp=Jul 10, 2008 10:51:16 AM EDT
Severity=Critical
Message=Failed to connect to database instance: ORA-04031: unable to allocate %s bytes of shared memory ("%s","%s","%s","%s") (DBD ERROR: OCISessionBegin).
Notification Rule Name=Send Email For Database Event
Notification Rule Owner=SYSMAN
Notification Count=1
The clients applications are having similar errors when trying to connect. This seems to be happening after replication has been running for a while (1 -2 weeks) on the SQL server 2005 side...
We are using Snapshot Replication for the 10g database (every 20 minutes)
and transactional replication on the 9i database...
We are replicating 28 tables from the 10g database (500Mb Via Snapshot Replication)
And 171 Tables for the 9i databases (Near 3Gb Via Transactional Replication)
Thanks for the help !

Here is an error from the 9i database Client: (this seems to be correct %s values)
ORA-04031: Unable to allocate 20236 bytes of shared memory("shared pool", "unknown object", "sga heap(1,0)", "session param values");

On the 10g database we get the error: ORA-12518: TNS:listener could not hand off client connection (DBD ERROR: OCIServerAttach).
The application for the Database 10g Is web based and uses Tomcat, I seems to get similar errors in the tomcat log:
java.sql.SQLException: ORA-04030: out of process memory when trying to allocate 1046552 bytes
