Pinning will prevent them from being flushed out due to inactivity and aging and will therefore prevent them for needing to be reloaded in the future i.e. You can use the following artcile to advise on this:ĭocument 726780.1 How to Pin a Cursor in the Shared Pool using DBMS_SHARED_POOL.KEEP In some cases, it may be possible to avoid problems with Authentication SQL by pinning such statements in the Shared Pool soon after the instance is started and they are freshly loaded. _enable_shared_pool_durations=false see Note 7039896.8 Unpublished Bug 7039896 workaround parameter

Level 266 will show us in what code it is executing which may help in locating any existing bug as the root cause.Įxamples of issues which can result in Authentication hangs The systemstate dumps should help in identifying the blocker session.

If possible, Two consecutive queries on V$LATCHHOLDER view for the case where the shared resource being waited for is a latch.

10-15 minutes of a time period during which several timeout errors were seen. Hence, systemstate dumps can be useful even when the time needed to generate them exceeds the period of a single timeout e.g. It is likely that the blocking session will have caused timeouts to more than one connection attempt.

Three consecutive systemstate dumps at level 266 during the time that one or more authenticating sessions are blocked.

Typical diagnostics used in such cases are the following: In such situations, we need to find out the blocker process holding the shared resource needed by the authenticating session in order to see what is happening to it.

Troubleshooting of Authentication hangs.

This results in the timeout being eventually reported to the authenticating session. That blocker session is itself occupied in a long-running activity (or its own hang) which prevents it from releasing the shared resource needed by the authenticating session in a timely fashion. The issue here is that the authenticating session is blocked waiting to get a shared resource which is held by another session inside the database. Other types of wait events are possible this list may not be complete.

Symptoms of such hangs will be seen by the authenticating session as waits for: It follows that any problem encountered during these phases which appears as a hang or severe slow performance may result in a timeout. The above SQL statements need to be Parsed, Executed and Fetched as happens for all SQL inside an Oracle Database. Differences may also exist from release to release.

When a database session is in the authentication phase, it will issue a sequence of SQL statements. WARNING: inbound connection timed out (ORA-3136). On a timeout, the client program will receive the ORA-3135 (or possibly TNS-3135) error:Īnd the database will log the ORA-3136 error in its alert.log: Starting with Oracle 10.2, the default for these parameters is 60 seconds where in previous releases it was 0, meaning no timeout.
