17.7.5 Deadlocks in InnoDB A deadlock is a situation in which multiple transactions are unable to proceed because each transaction holds a lock that is needed by another one. Because all transactions involved are waiting for the same resource to become available, none of them ever releases the lock it holds. A deadlock can occur when transactions lock rows in multiple tables (through statements such as UPDATE or SELECT ... FOR UPDATE), but in the opposite order. A deadlock can also occur when such statements lock ranges of index records and gaps, with each transaction acquiring some locks but not others due to a timing issue. For a deadlock example, see Section 17.7.5.1, “An InnoDB Deadlock Example”. To reduce the possibility of deadlocks, use transactions rather than LOCK TABLES statements; keep transactions that insert or update data small enough that they do not stay open for long periods of time; when different transactions update multiple tables or large ranges of rows, use the same order of operations (such as SELECT ... FOR UPDATE) in each transaction; create indexes on the columns used in SELECT ... FOR UPDATE and UPDATE ... WHERE statements. The possibility of deadlocks is not affected by the isolation level, because the isolation level changes the behavior of read operations, while deadlocks occur because of write operations. For more information about avoiding and recovering from deadlock conditions, see Section 17.7.5.3, “How to Minimize and Handle Deadlocks”. When deadlock detection is enabled (the default) and a deadlock does occur, InnoDB detects the condition and rolls back one of the transactions (the victim). If deadlock detection is disabled using the innodb_deadlock_detect variable, InnoDB relies on the innodb_lock_wait_timeout setting to roll back transactions in case of a deadlock.

Thread.It requires fewer resources as compared to processes.It takes more time to create and terminate a process as compared to a thread.It takes less time to create and terminate a thread as compared to a process.It usually run-in separate memory space.It usually run-in shared memory space.It does not share data.It shares data with each other.It can be divided into multiple threads.It can’t be further subdivided. 10. What are various sections of the process? There are basically four sections in the process as given below:Stack: It is used for local variables and returns addresses. Heap: It is used for dynamic memory allocation.Data: It stores global and static variables.Code or text: It comprises compiled program code. 11. What is a deadlock in OS? What are the necessary conditions for a deadlock? Deadlock is generally a situation where a set of processes are blocked as each process is holding resources and waits to acquire resources held by another process. In this situation, two or more processes simply try to execute simultaneously and wait for each to finish their execution because they are dependent on each other. We can see a hand problem in our system whenever a deadlock occurs in a program. It is one of the common problems you can see in multiprocessing. Necessary Conditions for DeadlockThere are basically four necessary conditions for deadlock as given below:Mutual ExclusionHold and WaitNo Pre-emptionCircular Wait or Resource Wait 12. What do you mean by Belady’s Anomaly? In the Operating System, process data is loaded in fixed-sized chunks and each chunk is referred to as a page. The processor loads these pages in the fixed-sized chunks of memory called frames. Belady’s Anomaly is a phenomenon in which if we increase the number of frames in memory, then the number of page faults also increases.

Firmware-Updates von 60 MB sind nicht ungewöhnlich. 18.2.19. Frage 19: Wie viele AC-Stromsensoren kann ich in einem VE.Bus-System anschließen?Das aktuelle Maximum liegt bei 9 Sensoren (seit Color Control GX v1.31). Bitte beachten Sie, dass jeder davon separat mit einem Assistenten in dem Multi oder Quattro, mit dem sie verkabelt ist, konfiguriert werden muss. 18.2.20. Frage 20: Probleme damit, dass Multi nicht startet, wenn CCGX angeschlossen ist / Vorsicht bei der Versorgung des CCGX von der AC-Out-Klemme eines VE.Bus-Inverters, Multi oder QuattroStellen Sie sicher, dass das GX-Gerät und MultiPlus mit der neuesten Firmware-Version läuft.Wenn Sie das CCGX von einem an den AC-Out-Port eines beliebigen VE.Bus-Produktes (Inverter, Multi oder Quattro) angeschlossenen Netzteil mit Strom versorgen, kann nach dem Abschalten der VE.Bus-Produkte aus irgendeinem Grund (nach einem Betriebsfehler oder während eines Schwarzstarts) ein Deadlock auftreten. Die VE.Bus-Geräte werden nicht hochfahren, bis das CCGX Strom hat ... aber das CCGX wird nicht hochfahren, bis es Strom hat. Siehe FAQ für weitere Informationen dazu.Dieser Deadlock kann durch kurzes Herausziehen des CCGX VE.Bus-Kabels korrigiert werden, an dem Sie beobachten werden, dass die VE.Bus-Produkte sofort mit dem Hochfahren beginnen.Dieser Deadlock kann auf zwei Arten vermieden werden:Versorgen Sie das CCGX mit Strom aus der Batterie; oderSchneiden Sie Klemme 7 im VE.Bus-Kabel, die ans verbunden ist CCGXDas Durchtrennen/Entfernen von Klemme 7 des VE.Bus-Kabels zum CCGX (braun/weiß gemäß der Farbkodierung des Standard-RJ45-Ethernet-Kabels) ermöglicht das Hochfahren der VE.Bus-Produkte, ohne dass das CCGX zuerst hochgefahren werden muss.Beachten Sie, dass bei Verwendung einer Redflow ZBM2/ZCell-Batterie Klemme 7 auch dann unterbrochen werden sollte, wenn das CCGX mit Gleichstrom versorgt wird, um die gleiche Blockierung zu Zeiten zu vermeiden, in denen der Redflow-Batterie-Cluster auf 0 % SoC steht.Der Nachteil des Abschneidens von Klemme 7 ist, dass das Abschalten des VE.Bus-Geräts weniger effektiv ist: Obwohl es den Ladevorgang und die Invertierung beendet, befindet es sich immer noch im Standby-Modus und zieht daher mehr Strom aus der Batterie, als wenn Klemme 7 an ihrem Platz gelassen worden wäre. Typischerweise ist dies nur in Marine- oder Kfz-Systemen relevant, wo es normal ist, das VE.Bus-Gerät regelmäßig auszuschalten. Für diese Art von Systemen empfehlen wir, Klemme 7 nicht abzuschneiden, sondern einfach nur das CCGX aus der Batterie zu versorgen. 18.2.21. Frage 21: Ich liebe Linux, Programmierung, Victron und das CCGX. Kann ich mehr machen?Ja, das können Sie! Wir beabsichtigen, fast den gesamten Code als Open Source zu veröffentlichen, aber so weit sind wir noch nicht. Was wir heute anbieten können, ist, dass viele Teile der Software in Skript oder anderen nicht vorkompilierten Sprachen, wie Python und QML, vorliegen und daher auf Ihrem Color Control GX verfügbar und leicht zu ändern sind.

The IssueIgnition version 8.1.46 introduced a fix for the ScriptManager where script initializations would potentially overlap, causing inconsistent object IDs and other ill effects. This was an attempt to address a longstanding, but subtle, scripting issue that could only be caused by unique edge cases of user code. After release we found that the fix could cause a deadlock if project library scripts were manually imported using the import statement after updating to Ignition version 8.1.46. We will be rolling back this issue by deploying an emergency release for Ignition version 8.1.47. SolutionIf you have recently upgraded to Ignition version 8.1.46 and are experiencing a deadlock on your Gateway, Designer, or Vision Client, revert back to 8.1.45 as a temporary workaround. Version 8.1.47 is scheduled for release within the next few days and is recommended for upgrade in order to receive all other listed features and bug fixes originally targeting 8.1.46..

Expression (Peter Geoghegan, Thomas Munro) § The table would be rebuilt with the correct data, but in an order having little to do with the index order. Fix risk of deadlock failures while dropping a partitioned index (Jimmy Yih, Gaurab Dey, Tom Lane) § Ensure that the required table and index locks are taken in the standard order (parents before children, tables before indexes). The previous coding for DROP INDEX did it differently, and so could deadlock against concurrent queries taking these locks in the standard order. Fix race condition between DROP TABLESPACE and checkpointing (Nathan Bossart) § The checkpoint forced by DROP TABLESPACE could sometimes fail to remove all dead files from the tablespace's directory, leading to a bogus " tablespace is not empty " error. Fix possible trouble in crash recovery after a TRUNCATE command that overlaps a checkpoint (Kyotaro Horiguchi, Heikki Linnakangas, Robert Haas) § § TRUNCATE must ensure that the table's disk file is truncated before the checkpoint is allowed to complete. Otherwise, replay starting from that checkpoint might find unexpected data in the supposedly-removed pages, possibly causing replay failure. Fix unsafe toast-data accesses during temporary object cleanup (Andres Freund) § Temporary-object deletion during server process exit could fail with " FATAL: cannot fetch toast data without an active snapshot " . This was usually harmless since the next use of that temporary schema would clean up successfully. Improve wait logic in RegisterSyncRequest (Thomas Munro) § If we run out of space in the checkpointer sync request queue (which is hopefully rare on real systems, but is common when testing with a very small buffer pool), we wait for it to drain. While waiting, we should report that as a wait event so that users know what is going on, and also watch for postmaster death, since otherwise the loop might never terminate if the checkpointer has already exited. Fix " PANIC: xlog flush request is not satisfied " failure during standby promotion when there is a missing WAL continuation record (Sami Imseih) § Fix possibility of self-deadlock in hot standby conflict handling (Andres Freund) §Comments
