Lock Files in Weblogic

There are cases where we see

Lock is owned by Another Session

Or

weblogic.management.ManagementException: [Deployer:149164]The domain edit lock is owned by another session in exclusive mode - hence this deployment operation cannot proceed.

These issues say about the lock being owned by another process.During these cases we need to make sure that the process releases the lock.

There are 4 types of lock available in weblogic

config.lok : This is used for the getting the file lock on the config.xml file.This lock ensures that the config.xml file is being owned by only one process at a time.This also ensures that the updates to config.xml file are done in a sequential order.

Location : cfgdir/config/config.xml

edit.lok : This was the most important lock that we see.This lock ensures that only one user is editing the configurations at any point of time. No 2 operations are performed at a same time

Location : cfgdir/

embeddedLDAP.lok:This file locks access to the embedded ldap server to ensure that only one person has access to the directory server at any time.

Location  /cfgdir/servers/<Server Name>/data/ldap/ldapfiles/

XXXServer.lok:This lock indicates that a given server is running.This ensures that the server is not started or running multiple times.

Location : /cfgdir/servers/<Server Name>/servername.lok

When a webloigc server is stopped, the embeddedLDAP.lok and XXXservername.lok are deleted automatically.

Connection Filters In Weblogic

Connection filters are one of the additional security Feature provides by Weblogic. Weblogic provides

Security for an domain level, application level and application component level using security roles and users.

Connection Filter is another feature provided by weblogic, which is a network layer security. These connection filters allow unwanted access to resources. For example these can be used in blocking a IP address in accessing the admin console of a weblogic.

Weblogic has a default connection filter implementation weblogic.security.net.ConnectionFilterImpl which connection filter rules that we configured and based on them it allows/blocks access to resources.

For adding a Connection Filter to a weblogic domain, Domain Name ->Security -> Filter. 

Connection Filter: weblogic.security.net.ConnectionFilterImpl
Connection Filter Rules:

IP address * * allow# Apache 

IP address * * allow#

Some thing like

173.222.34.54 * * allow#Apache

0.0.0.0/0 * * deny#Deny all

0.0.0.0/0 * 7001 deny

When We check in the config.xml file we can see,

 <connection-filter-rule>173.222.34.54 * * allow# Apache</connection-filter-rule>

<connection-filter-rule>0.0.0.0/0 * * deny#Deny All</connection-filter-rule>

<connection-filter-rule>0.0.0.0/0 * 7001 deny</connection-filter-rule>

The First line says to allow access to every thing for the IP address 173.222.34.54.The last  line will deny all traphic (0.0.0.0/0) to all local addresses (*) on admin port (7001).The Rules in here are validated from top to bottom.

There are some syntax rules while configuring the filters

• Each rule must be written on a single line.
• Tokens in a rule are separated by white space.
• A pound sign (#) is the comment character. Everything after a pound sign on a line is ignored.
• Whitespace before or after a rule is ignored.
• Lines consisting only of whitespace or comments are skipped.
• Filters are activated to all servers in your domain, so remember you can lockout yourself (admin console) or even internal weblogic communication between managed servers and the admin server.
• Filters are stored in the config.xml file, so if you really locked yourself out -> Look there

The connection filter syntax is

targetAddress  localAddress  localPort   action        protocols

targetAddress specifies one or more systems to filter.

localAddress defines the host address of the WebLogic Server instance. (If you specify an asterisk (*), the match returns all local IP addresses.)

localPort defines the port on which the WebLogic Server instance is listening. (If you specify an asterisk (*), the match returns all available ports on the server).

action specifies the action to perform. This value must be allow or deny.

protocols is the list of protocol names to match. The following protocols may be specified: http, https, t3, t3s,ldap, ldaps, iiop, iiops, and com.

If no protocol is defined, all protocols will match a rule.

There are cases where you will see Notices like

####<Nov 27, 2012 4:31:22 AM CST> <Notice> <Socket> <omhq19ea> < admin> <ExecuteThread: '5' for queue: 'weblogic.socket.Muxer'> <<WLS Kernel>> <> <> <1354012282145> <BEA-000445> <Connection rejected, filter blocked Socket[addr=x.x.x.x.x,port=62719,localport=29902], weblogic.security.net.FilterException: [Security:090220]rule 81>

####<Nov 27, 2012 4:49:25 AM CST> <Notice> <Socket> <omhq19eb> < admin> <ExecuteThread: '4' for queue: 'weblogic.socket.Muxer'> <<WLS Kernel>> <> <> <1354013365338> <BEA-000445> <Connection rejected, filter blocked Socket[addr=x.x.x.x,port=62941,localport=29802], weblogic.security.net.FilterException: [Security:090220]rule 107>

Just check the connection filters are according to the syntax.

Random Number Generation in Weblogic

The Generation of Random Number are done by using Math.random() or SecureRandom. The Source for generating the random numbers can be configured in such a way that they can depend on the Operating System. Java uses its own source for generating the Random numbers but for better random numbers, the source for generating the random numbers can assigned to the underlying operating System hardware Signals which are generated from the interactions from the network ,keyboard and other devices.

In RHEL, there are 2 files available that help in generating the Random numbers

/dev/random

&

/dev/urandom

The Random number generator uses hardware noises for generating the random numbers. The noise generated by the hardware is thus stored inside the entropy pool. The generator also has the information on how much bits of information is available in the entropy pool.

From using this entropy pool, the random numbers are generated.

The /dev/random will only return random date within the estimated number of bits of noise in the

entropy pool but one issue with this is the /dev/random will be blocked until additional noise is generated or bits available in the entropy pool. If no bits are available in the entropy pool, the /dev/random will be blocked.

The /dev/urandom will return as much data requested.

If your system does not have /dev/random and  /dev/urandom created  already,  they  can be created with the following  commands:

               mknod -m 644 /dev/random c 1 8

               mknod -m 644 /dev/urandom c 1 9

               chown root:root /dev/random /dev/urandom

The library used for random number generation in Sun's JVM relies on /dev/random by default for Linux platforms. For configuring the random number generation with Weblogic,

Check if /dev/random works fine

head -n 1 /dev/random

If the command returns immediately, you can use /dev/random as the default generator for SUN's JVM. If the command does not return immediately, use these steps to configure the JVM to use/dev/urandom .This can be configured as

-Djava.security.egd=file:/dev/./urandom and added to the Weblogic startup script
