• Capacity of the crypto ipsec Cisco ASA 9.1 stats system failures

  Hello

  I'm trying to find some performance issues on one ASA centralized and some site VPN settings.  I already address bits of fragmentation and flow control which seeks to solve performance problems, but I came across something that I can't identify to understand what he said.

  I can't seem to find any documentation that explains what triggers the counter for "Capacity of the system failures" on the stats command see the crypto ipsec:

  Hello

  What is the model of the ASA you have and how many vpn sessions you get on average during peak hours?

  Lack of capacity occurs when it is short of ability of the material or the use...

• ASA Site to not tunnel no transmission of traffic for some subnets after awhile

  Hello

  We have a question really strange tunnel from site to site on several ASAs.

  We organize VPN tunnels between a small site and three largest.

  The den has an ASA 5505, the other three principles are ASA 5510.

  One of the tunnels working for months without problems.

  Each tunnel has several class C network.

  example Site:

  -192.168.50.0/24 (named A1)

  -192.168.51.0/24 (called A2)

  Site b:

  -192.168.60.0/24 (named B1)

  -192.168.61.0/24 (called B2)

  On two faulty tunnels, all is well at the beginning. After a few days (1-14) some networks to cease to work. So I can ping both A1 and A2 B1 network networks, but only from A2 B2 network. Pings from A1 to B2 doesn't expire. The ASA site showed tx = 0 traffic for <=>A1, B2, but progressive count rx traffic. ASA b it shows rx = 0 to B2<=>A1 and tx counties upward.

  This happens unexpected after different periods. Sometimes he hits ASA on site B, where tx = 0, it is sometimes ASA on A site.

  I tried to fix it as a result of orders:

  ISAKMP crypto claire his
  clear crypto ipsec his
  clear xlate

  but nothing has worked. The only solution for now is to restart the ASA where tx County indicates 0. After restarting, everything goes well for a while.

  On one of the affected sites, we have a failover configuration - ASA. A failover of the active device also solves the problem. But if you change your prior back restart the old principal question will return immediately.

  I think that there is no configuration because:

  -All tunnels are configured in the same way, and one of them is running for moths without any problem

  -Tunnels work for all combinations of subnet after a reboot

  -The problem occurs after different and long periods of time. So I think that the period between failures is long to be caused by tunnel a.s.o. timeouts.

  All ASA are running 9.1. (5) 21.

  I updated the firmware of several releases these past few months and had the same problem with any version I tested.

  So I hope that someone else has also had this problem and found a solution.

  Christian Hey!

  Hopefully, solve or find the root cause?

  Thank you

• Out of HS crypto ipsec his

  Hello world

  When we sh crypto ipsec his it shows lo tof info

  Need to know what means ident Eve and away?

  local ident (addr, mask, prot, port): (10.0.x.x/255.255.255.255/0/0)

  Hello Manu,

  Virtually every SA will show you the traffic that is sent over the VPN (which is innitiating the traffic) in this case, we can see that we send on the VPN tunnel traffic from 10.10.x.x subnet other 10.

• Need to understand the basics of Oracle RAC and grid technology, for training

  I need to understand the infrastructure Oracle RAC and grid, a manager / training perspective.

  I see links here and here , so a few questions:

  -What is the fundamental difference from the layman's point of view (for example, a Manager)?

  -What training options are available for a generic 11g DBA to learn this new technology? I've seen this course from a partner of Oracle ("" courses: Oracle 11 g: RAC and Grid Infrastructure Administration accelerated Release 2 ""), to a boat load of money, during 5 days I think. So we are looking for something a bit more reasonable (and accessible), for example, books, online, etc.

  For a very basic definition, ACR is technology that is used by the database and IM is the infrastructure that makes the CAR work. In a response to the forum, this is probably all that can be said about the two. For a very long answer, you should read the links you cited.

  # 2, the course you are looking at is called accelerated because it combines two courses in one week training-RAC (4) and GI (3). So it's a day 7 curriculum that we would do in a 5 day course and who must justify its cost. But let me say, it's a really very good. But on the other side, it can be pretty intimidating to someone who does not already know these technologies. So I suggest that you send your team to each course individually and no doubt after doing some research. They can start to read the following books

  Pro Oracle Database 11g RAC on Linux

  https://www.mheducation.co.in/HTML/9781259004063.html

• Flash newbie needs some advice on a project

  Hey guys,.

  Thought I'd ask you guys to a general approach on a project I'm starting.  I have a background in computer science, so I lose patience with some of the beginner step by step tutorials that are out there online / in books.  What I lack, it is for you guys to let me know what will be important for me to learn what I want to do and what are the aspects of the Flash I can go without.

  I'm a grad student in Psych clinical and I want to build an interactive processing application.  Which basically translates to is that he will have a series of screens with text, sound, and video clickable icons that will show small films, I developed that my views on the principles of different treatment.  Anyway, I just wanted to know if you guys could give me advice on the best way to do it.  I can animate text and it's kind of basic, but I feel like I kind of sense in the dark right now and do not want to waste too much time on dead ends.  If you guys can give me an idea about the basic components of Flash, I'm going to need a solid understanding of creating a project like this, I would really appreciate it.  I'm sorry if it is vague, just trying to reduce the amount of time I spend of experimentation and if you guys could tell me precisely these modules/tools in the application that I have to use to do this I can take it from there.

  Thank you!

  -Ricky

  If you are looking for shortcuts, you're not likely to find.  The essential elements you need to know to start with the basics and expand from there.

  One essential thing you should learn is how to find and solve things by yourself using the Flash help documentation and a good search engine like Google.  Almost all the objects/classes have 3 basic elements (properties, methods, events) you need to understand how use/manipulate, and they are all identified in the help documentation.

  If you want to work with videos, start digging to learn the different ways that you can integrate... using a FLVPlayback component or the NetStream class.  If you want to learn how to work with audio, then dig learn how to use the Sound class.

• Need some tips to merge the two table-manipulation functions

  Hi guys!

  Thanks to Johnsold, Helmut O'Brian and Jcarmody, who helped me through a string function complicated (for me, the noob of LV), I got away with my project and I'm very close to its end.

  As I've described it here I wanted to explore an array of words combined with-, i.e. C1 - C10. Help, when I arrived, I was able to do. I also learned a few things and was able to do the following:

  Original array: new table:

  R1                                                       R1

  R2                                                       R2

  C1-C3                                                  C1

  K1                                                       C2

  C3

  K1

  I have this:

  Original array: new table:

  R1                                                       R1

  R2,R4,R7                                             R2

  C1                                                       R4

  K1                                                       R7

  C1

  K1

  I was also able to combine these two functions

  Now, back to my problem.

  Until now, it was just a 1 d array that I worked with. In fact, it's a 2D array, I read a. CSV file:

  

  As you can see there are a few places where things is combined with either - or by commas. I need to widen the first column as described above and as resolved in the thread I mentioned. Fact! No problem. I extracted the first column in table 1 d. Then expand it. Now, I need to replace in the original array and also expand all.

  It should then look like this:

  

  Then I only need to copy the position of the R6 line and paste it in the empty fields:

  

  I enclose below two screws. Start by opening the main.vi. Then copy.vi. I tried to describe the problem here too. You can see what I've accomplished and what is missing.

  Tasks:

  1. replace the column expanded in the original array and expand all.

  2 copy the needed lines.

  In the main.vi, I do the 1 d expansion, but I have the problem with the expansion of table 2D. In copy.vi, I managed to copy the lines. If this part is done.

  Basically, I need some advice on enlargement that I do and how do I get the 2D table also expanded. Because I have not much experience, I feel more comfortable working with 1 d arrays. But I can't seem to get any further with this 1 d-> expansion 2D.

  I also really can't seem to find a smart way to implement my function of copy-line-in the main.vi.

  P.S the joint screws are manufactured in LV2010.

  Fortunately, I can attend some courses of basic home OR here in Norway, but so far, I'm still learning and I think that sometimes, I try to do things that are way out of my League

  I don't know what I did but it works now

  Thanks for the help, same!

  You are even welcome!

  

  Have attached the file if anyone wants to see what I did.

• Need to understand what this command is

  I need to understand what this command does, it was on a router that I just picked up and I am familiar with this part of the order.

  IP nat inside source static tcp 192.168.5.201 mail_192.168.7 25 203.161.81.22 25-extensible route map

  I ask is because the customer has a scanner that sends scanned document via smtp to an off-site mail server which, in turn, sends mail to the user.  Before that, they used an internal e-mail server (. 201). What is mail users can go out and reach their destination.  However, any scanned mail does not work and I'm trying to understand why.  The scanner has an internal ip address, which is 192.168.5.25, the 192.168.5.201 is a mail server that was running and this command seems to be allow e-mail from the mail server (. 201) to send mail to another location through VPN tunnel to our other offices. What I'm trying to understand is the order indicating that the mail de.201 can go to the 192.168.7 network via the 203.161.81.22 port road 25.  If this is true who will stop mail from other devices out via 203.161.81.22 on port 25

  Hello jonl711

  As you know, do the NAT ports on a Cisco router, add a line for each of them, such as:

  IP nat inside source static tcp 192.168.5,201 25 X.X.X.X 25 - card expandable route

  Here we ¨nating¨ port 25 to the machine 192.168.5.201 in our network, where XXXX is the our public ip address.

  That said, here I explain what each command

  access-list 112 refuse host ip 192.168.5.201 192.168.1.0 0.0.0.255

  access-list 112 refuse host ip 192.168.5.201 192.168.7.0 0.0.0.255

  access ip-list 112 allow a whole

  --> Here you can create an access list who deny ip 192.168.5.201 go to 192.168.1.0 and 192.168.7.0

  mail_192.168.7 allowed 10 route map

  corresponds to the IP 112

  --> Here you create a ¨rule¨ to match the access list you created.

  IP nat inside source static tcp 192.168.5.201 mail_192.168.7 25 203.161.81.22 25-extensible route map

  --> and here you are mapping the IP 192.168.5.201 with port 25 (SMTP) that go outside with the IP 203.161.81.22 with port 25 (SMTP) and get a match with the road map

• Output of "crypto ipsec to show her.

  Hello

  In a VPN l2l baseline using ezVPN, the server behind the NAT, client device using 3 G. What would be the reason to have the output of the show crypto ipsec sa, a current peer differs from crypto remote endpoint on the server?

  Thanks for your help.

  David

  Given that it is behind a NAT and NAT device is only the layer 3, and it changes the contents of the IPSec VPN when negotiating because it is encrypted, so you might see counterpart current differs from endpoint remote crypto on the server.

• Need some clarification on the operation of H323 with VCS-C/E

  We have our points of endpoints connected to the VCS - C with a VCS-E. When an end point called another unit through IP H323 the VCS - C does anything with the video/audio? He plays the intermediaries? Or is the VCS - C just let both units communicate DIRECTLY with each other (even when I see the appeal in calls in course VCS-C)?

  I try to debug problems with call and need some explanation on how it works.

  Thank you

  RB

  By default, call Routed mode should be on.  This means that the installation & signalling through the VCS, but all media streams are direct between endpoints.

  Thanks in advance.

  Hello

  > Is this really necessary until the upgrade process, which is the real benefit?

  SQL > exec DBMS_STATS. GATHER_DICTIONARY_STATS;

  1 prior to advantage, was causing problem - degrade the performance of your database? What its not beneficial?

  Logically, if you see the dictionary is on your information about your database - default provided with products and items of custom applications. Now during the upgrade - given that the term refers to a new addition of things monofores or gout or new table segmetns is getting added to your existing dictionary. Now, if I don't keep his stats up to date on my dictionary itself then update itself is the process of taking time. It will hit my sqls himself upgrade performance

  Thus, in order to reduce this impact - prior to your downtime in pre-upgrade task you can collect stats on your dictionary. While during upgrade if you run / run research in its stats its would take very little time to collect minor statistics and it will not affect the order of execution of ddl or dml SQL out that focus on changes in your dictionary.

  > To activate my database in NOARCHIVELOG MODE, it provides massive difference during the upgrade process?

  SQL > alter the noarchive base newspaper;

  2. I don't know who s/n, suggested the above step to achieve. Not a good, better I would have fired the DBA immediately. Despite that I have perform the update level or no, keep you the database in log mode archive.

  To upgrade, its gives no performance improvement for your upgrade process. What is your intention on the upgrade?

  You want to run through the upgrade in 15 minutes? Listen you dictionary database or application objects develop the direcrtly would increase the upgrade. Is not all synonyms - maybe a few times - up to what the table - dictionary of data updated in upgrade tis - for example bitand 12 c on synonyms function table is changed, so his punches performance - it is not a must and was cause depends on the base of the environment for the environment. Reason for this how you store your environment that will reduce the burden of upgrading

  > TRUNCATE table audit SYS. AUD$

  3. I hope I answered this question is another thread

  > Length upgrade depends on.

  Size of the database

  Number of synonyms

  Number of data files

  Size of the recovery logs

  Number of installed components

  For the types of data and not the XDB user objects.

  It is partially dependent on the data dictionary and how clean it is, whatever. Clean - number sense of invalids and statistics.

  Number of components installed in a concern - it might be a minimum until we reached and deliver the bad SQL with performance.

  Size of database and data file and restore logs is out of reach... If my database is to have 10 k datafles, my upgrade script will go and touch all the header files of data blocks, is indicated in MOS linsks or docs. No, he will not be at level of offers to work on something of dictionary and Oracle database metadata.

  > Deleting FILES of network completely from 10 g $ORACLE_HOME, creating newfiles in 11 g $ORACLE_HOME

  You have any load 2 mins to copy files during upgrade spending. Fact the DBA is so busy that he can afford 2 mins tasks.

  It is out of reach, you have to manage.
