After an AIX 7.1 server reboot, there was one agent which did not started. The command emctl start agent resulted in a java.lang.OutOfMemoryError: Java heap space message. In the agent subdirectory some dumpfiles were created: -rw-r—– 1 oracle dba 291373 Oct 19 11:00 javacore.20151019.110002.14876844.0002.txt -rw-r—– 1 oracle dba 22182281 Oct 19 11:00 heapdump.20151019.110002.14876844.0001.phd -rw-r–r– 1 oracle dba 167408 Oct 19 11:00 Snap.20151019.110002.14876844.0003.trc First I took a look in the agent logfiles to gather more information. /u00/app/oracle/product/agent12c/agent_inst/sysman/log/emdctlj.log 2015-10-19 10:59:11,711 [1:F7DA781F:main-16449708] INFO – EmdCtl Timezone = Europe/Zurich 2015-10-19 10:59:11,884 [1:F288756D:main-11600120] INFO – EmdCtl Timezone = Europe/Zurich 2015-10-19 10:59:13,584 [1:2CF29A0A] INFO – Disconnecting: client terminus 2015-10-19 10:59:13,585 [1:2CF29A0A] INFO – stdout: Status agent Failure:unable to connect to http server at https://srvaix111.mvn.ch:3874/emd/lifecycle/main/.

Read MoreLost Disk after DBaaS Restart via Cloud Service Console
I have created a DBaaS instance three weeks ago, and now it was time to attach new storage in the Oracle Compute Cloud Service to have additional disk space for some Trivadis tools. But after a reboot with a mouse-click in the DBaaS Cloud Service Console, the disk was lost and had to be re-attached. The procedure to add additional storage is documented in this Oracle tutorial: http://www.oracle.com/webfolder/technetwork/tutorials/obe/cloud/dbaas/OU/IntroDBaaS/AddStorageDBaaSInstance/AddStorageDBaaSInstance.html Creating additional Storage in the Oracle Compute Cloud Service In the Create Storage Volume menu, I have created a new storage volume of 10GB and attached it to my running DBaaS instance called TrivadisExPerf. OS Verfication After some minutes waiting, I logged in on the database server to verify the operation. The…

Read MoreOracle Enterprise Manager 12cR5 – Clone a PDB to the Oracle Cloud
Cloning an on-premise PDB to the Oracle Cloud is basically done in three steps. 1. Select your PDB – 2. Start Clone Menu – 3. Verify new PDB. In the basic clone menu, Oracle uses some default settings in the background, for example the source datafiles will be packed in a compressed file which is located in /tmp directory of the source server. When your /tmp directory is too small, the clone process fails. Why this directory is used? I don’t know. But it could be a problem when you clone bigger databases. Maybe we can edit the clone procedure, but this is a task for me for a day when it’s raining outside… All cloning steps are well monitored,…
