GoldenGate ACCESSRULE – OGG-01235 Command not allowed by receiving manager process.

GoldenGate Datapump or Extract Abend with OGG-01235?

ERROR OGG-01235 Command not allowed by receiving manager process.


Sounds remote GoldenGate client are denying Datapump / Extract remote connection.

Suggest check and edit GoldenGate manager parameter file.

--IPs addr from source GoldenGate Pump

 Oracle documentation is good here.
Valid for Manager

Use ACCESSRULE to control connection access to the Manager process and the processes under its control. You can establish multiple rules by specifying multiple ACCESSRULE statements in the parameter file and control their priority. There is no limit to the number of rules that you can specify. To establish priority, you can either list the rules in order from most important to least important, or you can explicitly set the priority of each rule with the PRI option.

ORA-00001: unique constraint (RMAN.CKP_U1) violated

Don’t create so much expectations on this post.

This is because I don’t exactly fixed the issue, but workarounded…
The thing is: This error is caused in catalog database, so the workaround is simple: do a RMAN-nocatalog, I mean, simply don’t connect in catalog to perform the backup.

After completing the backup, I’d suggest you to force a synchronization with command “RESYNC CATALOG“. In worst case, on next execution the implicit resync will fix everything. 🙂

There is no bigger explanations on this, but you can same workaround in MOS Bug 12588237 – RMAN-3002 ORA-1: unique constraint (ckp_u1) violated after dataguard switchover (Doc ID 12588237.8).

And this is it for today!
See you next week!

EMagent 12c with high number of threads causing “su: cannot set user id: Resource temporarily unavailable”

Hello all,
Yeah, these days I got some errors and when validating the server found the fllowing error:

su: cannot set user id: Resource temporarily unavailable

As you can imagine, in order to fix the issue, I adjusted the /etc/security/limits.conf increasing oracle nprocs to:

oracle           soft    nproc           4047
oracle           hard    nproc           20384

Ok, turns out that after a while I got the same errors again…
After some investigating I find that the EM Agent process was with 5020 threads!
Take a look:

Oracle Database 9i: Where is my SQL_ID? Which SQL is in lock?

Struggling with that, right?
As you know, in Oracle Database 9i the view V$SESSION doesn’t have SQL_ID column…
So how to map SQLs in my database? And, for example, how to get the SQLs causing a lock?

In the end of the day, the SQL_ID is only a representation of the hash_value of an SQL. You can even make the translation from SQL_ID to Hash Value as you can check on this post by Tanel Poder.

Ok, but I have to map which sql is causing the lock in my 9i database, how can I do that?

Here it goes:

If session status is ACTIVE:

SELECT s1.sql_text from v$sqlarea s1,v$session s2 where s2.SID=&sid and s2.SQL_ADDRESS = s1.ADDRESS

If session status is INACTIVE:

SELECT s1.sql_text from v$sqlarea s1,v$session s2 where s2.SID=&sid and s2.prev_sql_addr = s1.ADDRESS

You’re welcome! 😉

See you next week!

OGG-01411 – Cannot convert input file ./dirdat/xx with format RELEASE 9.0/9.5 to output file ./dirdat/zz


If you search solutions to this Error, you will perceived only one documented root cause:


OGG-01411  Cannot convert input file ./dirdat/xx000549 with format RELEASE 9.0/9.5 to output file ./dirdat/zz000034 with format RELEASE 12.1.


“The output trail of the data pump has a different format (version) than the input trail of the data pump”

If you are using GG 12.1 version, and all trails (rmttrail and exttrail) are correctly set with “format release”, you fell into a bug.

Oracle recommend to do upgrade to GG 12.2.

To work around this issue and start process, you need write a new trail, perform etrollover and reposition pump process.

On the Target System, process works fine, but not receive new trails, because pump process are abended.
