Hi All,<\/p>\n

Today I would like to cover firewall timings management in access environment.<\/p>\n

Here, we have OAM 10g , two SSO servers(OID\/OSSO 10g-10.1.4.3.0), oracle portal 11g, OBIZ, SOA, Seibel and etc.<\/p>\n

Integration details, Portal having own SSO server(OID\/OSSO 10g-10.1.4.3.0) and portal application registered as a partner application in portal OSSO. Portal OSSO server is integrated with OAM for centralized authentication because in our project more than 10 application integrated with OAM10g(10.1.4.3.0) for SSO.<\/p>\n

All applications are integrated with OAM 10g. We are accessing all applications through Oracle Portal(11g) application by clicking links under portal workspace.<\/p>\n

We were tested application performance by using load runner. During run our OAM server went down automatically and I have noticed some error in logs.<\/p>\n

ERROR —\/usr\/abuild\/Oblix\/coreid1014\/palantir\/webgate2\/src\/web_gate.cpp:143: Error: Exception re-thrown from ObWebGate::Init( <NULL> = <NULL>, <NULL> = <NULL> )%0a..\/obthread.cpp:748: Error: Exception re-thrown in ObThread::Start%0a..\/obthread.cpp:726: Error: Create thread failed, error message is Resource temporarily unavailable%0a<\/span><\/p>\n

\/\u2026\/oblix\/apps\/common\/bin\/start_access_server: fork: Resource temporarily unavailable<\/span><\/p>\n

Could not start the Access Server. The watchdog is stopping.<\/span><\/p>\n

This usually means you have hit the limit on the number of running processes, and cannot start any more.<\/p>\n

So I thought it was happened due to heavy load in OAM, then I tuned all OAM components as mentioned in this link<\/p>\n

http:\/\/docs.oracle.com\/cd\/B28196_01\/idmanage.1014\/b25344\/perform.htm#sthref24<\/a><\/p>\n

But no luck, again OAM server went down automatically but this time OAM handled more time compare to previous time failure. Again finger crossed :(.<\/p>\n

After long investigation, the real root cause has been find out. The real problem due to firewall timeout.<\/p>\n

Here, I have specified my workarounds.\u00a0<\/p>\n

    \n
  1. Validate any firewall exist between Access Server and LDAP ? (is it OID ? or active server ).<\/li>\n
  2. Validate any firewall exist between Access Server and webgate ?<\/li>\n
  3. ran immediately once OAM server went down
    \nnetstat -a > connections.txt<\/li>\n
  4. In connection.txt I have noticed 11k connections in TIME_WAIT state. It is clear that server restart due number of big connections , and most probable firewall is involved here.<\/li>\n
  5. Implemented doc id : 1253194.1<\/li>\n<\/ol>\n

    “Configuration Recommendations
    \nThe overall recommendation is simply to keep firewall connection timeout limits higher than the Access Clients’ maximum connection time….”<\/p>\n

    The problem is vanished and our performance test went smoothly without any issues. Hope, this post helped you. \ud83d\ude42<\/p>\n","protected":false},"excerpt":{"rendered":"
