[former_member315418]

Hi ,

I have recently updated the stack of my Solution Manager 7.1 . But post-installation , i am facing an issue regarding J2ee Engine startup.

it displays the below message when i try http://<localhost>:<port>/ .

I have checked all the instances in SAP MMC . all are running perfectly.

when i call LMDB and SM_WORKCENTER, url runs perfecltty.. Its only when i try

http://<localhost>:<port>/ .

http://<localhost>:<port>/ sld.

http://<localhost>:<port>/ nwa., it shows below message....

I have searched all the blogs and followed the below notes, but could lead to solution.

Please help asap, as we have to upgrade our other server, for which we need stack file from SOLMAN.

Hello

Is the ABAP up and running ?

I can see that the Java stack has been started.

[Thr 9352] Thu Dec 19 02:25:20 2013
[Thr 9352] JLaunchISetState: change state from [Starting applications (10)] to [Running (3)]

Are you using the right port to access the URL ?

If yes then check whether the J2EE stack is in safe mode after the upgrade.

If yes then follow these.

1267123 - System remains in SAFE mode after update

Hi Reagan,

ABAP is running... even when i call LMDB and SM_WORKCENTER.. java url also work..

only when i go to homepage, sld or NWA - http://localhost:8000, it doesnt work .

it shows message (as screenshot attached in the first message).

Moreover-- system is already in SAFE mode in configtool.

Solution manager is 7.1

I had tried everything given at blogs and forums like increasing MaxPermSize, shrunk the database, etc... nothing worked.

Please help me.

System should not be in safe mode.

To Disable the safe mode follow and restart...

Safe Mode in the J2EE Engine (SAP Library - Administration Manual)

Hi Reagan,

It shows same message for http://FQDN:50000/nwa and http://FQDN:8000/nwa :

SAP NetWeaver AS Java is starting... If this state does not change within a few minutes, please contact your system administrator. Check the recommendations in SAP Notes: 943498, 764417 Message: Dispatcher running but no server connected!

Can you restart system and after that provide more recent log files?

[former_member193518 · Accepted solution]

I've just looked at nearly the first line in the defaulttrace you supplied.

Looks to me like you have a UME connection problem.

Can you check in ABAP stack that the user account you use for UME is not locked, password valid and has correct role assigned (and role profile is generated).

Thanks.

Hi Mohit,

At the trace you can find

Error getting the server-side naming service functionality during getInitialContext operation

and

[sld] Cannot get a naming context.

Use visual administrator and check if SLD hostname port and user is valid.

choose server_0 - service SLD data supplier and HTTP settings and infromation tab,

BR,

K.

Hello Kamil,

thanks for the relpy.. could you please tell where should i check sld hostname and user in visual administrator.. as in SOlution manager 7.1 , visual administrator is replcaed by Nwtvear Administrator..

which is again not working.. http:<localhost>:<port>/nwa

Please help us more.

Regards

[Former Member]

Hello Mohit,

AFAIK NWA replace visual administrator from NW 7.1 (not SolMan 7.1)

Replacement of Visual Administrator by SAP NetWeaver Administrat - SAP NetWeaver Operations - SAP Li...

So start visual administrator from \usr\sap\<SID>DV*\j2ee\admin\go.bat or go.sh and check connection from AS Java to SLD.

Hi,

Please paste the screenshot of JCMON as below:-

go to cmd and write jcmon pf=/usr/sap/<SID>/SYS/profile/<SID>_J00_<HostName>.

Also paste the below logs of:-

Bootstrap logs are located in \usr\sap\<SID>\<instance>\work

In these logs you find log-information on the beginning of the startup process of the J2EE engine.

Most important ones are:

dev_bootstrap

dev_dispatcher

dev_server

Dispatcher logs are located in \usr\sap\<SID>\<instance>\ j2ee\cluster\dispatcher\log

Specially check the latest defaulTrace.<x>.trc

Server logs are located in \usr\sap\<SID>\<instance>\ j2ee\cluster\server0\log

Specially check the latest defaulTrace.<x>.trc

Hi,

I just faced the same Problem, and it might that you are runnung out of memory.

Check ST22 for shortdumps like:

Category               Installation Errors
Runtime Errors         PXA_NO_SHARED_MEMORY
Date and Time          19.12.2013 08:33:47

Short text
     1000000 kilo bytes of shared memory for PXA not available.

I added an undocumented parameter to the Instance Profile which keeps this shortdumps somehow "under control"

abap/buffer_fragments = 1

It can happen, that when you have to apply Notes like

1922837 Corrections for unified rendering 702/15 VI (ABAP renderer)

1922838 Corrections for unified rendering 702/15 VI (UR-mimes)

that you have to increase some ABAP parameter dramatically

abap/heaplimit = 200000000

abap/heap_area_dia = 1000000000

Don't forget the Parameter abap/shared_objects_size_MB = 256

for your shared memory areas. YOu can check them with Transaction SHMM

I also have to restart my Solution Manager 7.1 based on SP10 several times in teh last weeks.

Good Luck

Best Regards Roland

Hello Roland,

I have checked the ST22 logs.. and found COMPUTE_INT_TIMES_OVERFLOW dump frequenlty occurring,

I am searching to for this dump... also will try to implement your suggestion of adding parametrs.

Will let you know  the result.
