ODP: JDBCRealm reconnect problems?
i had a similar problem and solved it by changing connectionURL to: connectionURL="jdbc:mysql://localhost/dbase?user=somebodyamp;password=secre t" and commenting connectionName and Password. vVolf -Oryginalna wiadomooe- Od: Vladimir Grishchenko [mailto:[EMAIL PROTECTED]] Wysano: 16 marca 2001 20:45 Do: [EMAIL PROTECTED] Temat: JDBCRealm reconnect problems?

Re: ODP: JDBCRealm reconnect problems?
Hi, I've had this as well. Solved it by customising JDBCRealm to use database connection pooling - perhaps a little heavy handed ;-). As far as I could make out the problem seemed to be related to the wait_timout variable set to 28800 by default. According to earlier posts 1) This bug is fixed in 3.2.2. , 3.3 and 4.0 2) Can also be solved by adding ;autoreconnect=true to the db connect string (haven't tried this myself) Andrew On Mon, 19 Mar 2001, you wrote: i had a similar problem and solved it by changing connectionURL to: connectionURL="jdbc:mysql://localhost/dbase?user=somebodyamp;password=secre t" and commenting connectionName and Password. vVolf -Oryginalna wiadomooeæ- Od: Vladimir Grishchenko [mailto:[EMAIL PROTECTED]] Wys³ano: 16 marca 2001 20:45 Do: [EMAIL PROTECTED] Temat: JDBCRealm reconnect problems?
